I almost immediately discounted the Tab A, as it's simply-HD screen, while looking good color-wise, simply did not cut it resolution wise. On the other hand the Windows Pro version of Surface will have a x PPI screen, and it is quite possible that it will be comparable in sharpness to the new iPad 3 with x PPI. Next we measured the Color Gamut, something where almost all mobile LCDs come up short in order to improve power efficiency and battery running time.

None-the-less sapphire is already being used in a number of mobile smartphones from Huawei, Kyocera, and Vertu, for example. And given the widespread consumer perception of sapphire as a very rugged, scratch resistant and a premium luxury item together with its rapidly falling production costs, means that sapphire will find its way into an increasing number of smartphones.

However, a major issue, as I have pointed out many times, is that sapphire has roughly double the screen reflectance of Gorilla glass, so smartphones with sapphire are much harder to see and read in ambient light as a result of the significantly greater reflections off the screen, which washes out the displayed images in both contrast and color.

Screen reflections are already a major problem with glass, but with sapphire doubling them has been a major hurdle, up until now An important new high technology breakthrough has produced Enhanced Sapphire that significantly lowers the screen reflectance of sapphire to much lower than glass, turning its former major disadvantage into a major new advantage.

We have done extensive Lab tests and the results are very impressive - Enhanced Sapphire has the lowest reflectance we have ever measured. A technical note, this isn't an Anti-Reflection AR coating, which would scratch off easily and defeat sapphire's tremendous scratch resistance - so Enhanced Sapphire is now number one in scratch resistance, low reflectance and performance in high ambient light.

In addition, displays using it could run with lower screen brightness and result in increased running time on battery. This new production ready low reflectance Enhanced Sapphire will undoubtedly be one of the major new advancements for smartphone displays, and is likely to go mainstream in the very near future for those companies that adopt it.

And this is just the tip of the iceberg It's all still under an NDA, there is much more to come, so stay tuned The likelihood of sapphire appearing on the iPhone 6 was close to zero because it will probably take at least another year for everything to come together.

It is important to note that sapphire has some downsides over and above its much higher cost and manufacturing complexity. The most important issue for display performance is that sapphire has almost double the screen Reflectance of glass due to principles of optics, so it will be harder to read sapphire screens in high ambient light.

That might be one reason why the recently announced Apple Watch Sport edition has a cover glass rather than sapphire like the other models - because it is much more likely to be used unshielded in high ambient light outdoors.

Another reason is that while sapphire is very hard it is also brittle and is likely more prone to impact breakage, which is more common in sports situations. So, if given the choice, I personally would choose a cover glass with its better screen visibility and breakage protection.

Others may find the scratch protection more important. The previous record holders all had about 4. The much lower Reflectance improves screen readability, image contrast, and color saturation in ambient light by almost 2: Anti-Reflection coatings are used in just about all high-end lenses and related optics.

The problem is that most coatings scratch easily and show fingerprints easily. Apple or more likely one of its suppliers has found something that doesn't scratch easily or show fingerprints and works well on Tablet and Smartphone touch screens.

Other manufacturers will need to implement similar Anti-Reflection coatings on their Tablets and Smartphones in the near future in order to stay competitive. Our Innovative Displays and Display Technology explains why The Next Generation of Mobile Displays The best performing LCD and OLED displays are now delivering impressive sharpness, brightness, low reflectance, high color accuracy, accurate image contrast, and great viewing angles.

So what comes next? Essentially all published display specifications and factory calibrations are based on performance in absolute darkness 0 lux, but mobile displays and even TVs are seldom viewed in the dark.

Even low levels of ambient light significantly affect the image and picture quality. At lux, which corresponds to typical indoor office lighting, the on-screen colors are washed out by the reflected ambient light, typically reducing the on-screen Color Gamut from percent down to 80 percent, plus the image contrast is also significantly affected.

And it gets worse as the ambient light levels increase. So here is what needs to come next The most important improvements for both LCD and LCD mobile displays will come from improving their image and picture quality and screen readability in ambient light, which washes out the screen images, resulting in reduced image contrast, color saturation, and color accuracy.

The key will be in implementing automatic real-time modification of the display's Color Gamut and Intensity Scales based the measured Ambient Light level in order to have them compensate for the reflected light glare and image wash out from ambient light as discussed in our Innovative Displays and Display Technology and SID Display Technology Shoot-Out articles.

The displays, technologies, and manufacturers that succeed in implementing this new high ambient light performance strategy will take the lead in the next generations of mobile displays Follow DisplayMate on Twitter to learn about these developments and our upcoming display technology coverage.

One of the world's leading companies for ProAV display calibration mentioned us on their website: Raymond Soneira of DisplayMate Technologies. Ray always reports exactly what he finds, no matter whom it might offend.

Display and video industry organizations and publications: For example, see this recent review in phone Arena. The problem is that these reviewers are not scientists or display experts, and are using canned display calibration software incorrectly in order to test a display, which produces incorrect results and bogus conclusions.

Below is a brief semi-technical analysis The reviewers are using retail display calibration software products that use a Color Difference measure called dE, which includes a Luminance Brightness Error component in addition to the Color Hue and Saturation Chromaticity Error component.

The eye sees and interprets brightness and color as two separate visual issues - dE combines them together. So all conclusions based on using dE for Visual Color Accuracy are incorrect. Since the eye sees color and brightness as two separate visual issues I measure and analyze them separately.

Compare my very precise and detailed Absolute Color Accuracy plots with their crude figure. The Galaxy S5 has 5 Screen Modes: Note that the Galaxy S5 has 5 different Screen Modes, the Cinema and Professional Photo Modes are very color accurate, whereas the 3 other Screen Modes are intentionally vivid and therefore intentionally not color accurate.

Some reviewer figures, numerical results and screen shots are for the intentionally vivid modes, which is misleading. Accurate Galaxy S5 Color Accuracy: Our measurements are made in our world-class Display Test Lab using a Spectroradiometer and expert mathematical data analysis.

My scientific credentials are listed here and here. Some Additional Reviewer Inaccuracies: The reviews are also loaded with many other technical inaccuracies - one example, using the very old and long obsolete CIE Color Diagram with x, y coordinates, which has large color non-uniformities so that it is not useful for judging or evaluating Color Accuracy.

Another recurring problem is reviewers using inexpensive Colorimeters, which are much less accurate than the Spectroradiometer we use for our lab measurements. The phone Arena derived Intensity Scale Gamma of 2.

Bogus Reviewer Results and Conclusions: Again, all conclusions that are based on using dE for evaluating Visual Color Accuracy Hue and Saturation are completely wrong and are the result of reviewers, who are not scientists or display experts incorrectly using and interpreting canned display calibration software.

My correct and accurate Galaxy S5 Color Accuracy results are here. Click on the links below for each topic. It's not a consumer product show but rather where manufacturers show off their latest and greatest display technology that will make their way into the upcoming generations of consumer products in the near future.

I spent most of my time in private meetings rather than cruising the show floor, but here are a number of general interest display products that caught my attention.

A revolutionary new technology that efficiently increases the color saturation and color gamut of LCDs by up to 50 percent for Smartphones, Tablets, HDTVs, and large monitors.

They use quantum physics to efficiently translate the color spectrum of the LED backlights for LCDs into precise and narrow red, green, and blue spectra for the LCD panel. This not only efficiently increases the brightness and power efficiency of the display but the narrow spectra should allow the screen's overall reflectance to be reduced.

I saw several display prototypes, including some that should be in production in the near future. Be on the lookout for them Both are in production but not yet available in the USA. The demo videos that were running at the show were seductively spectacular.

We hope to do an in-depth scientific Display Technology evaluation in our Lab sometime soon. Sharp showed a prototype of an incredible It is most likely destined for a notebook, small TV, or a monitor - we'll see where it shows up On the first day LG allowed people to hit their OLED display with a hefty carpenter's rubber mallet to prove how indestructible they are.

But some attendees took that as a challenge and brutally smashed away, so the mallet was taken away for day LG showed a 4. It worked impressively well, with a nice demo that continued to demonstrate good 3D as I changed my viewing position.

Displays for Tablets and Notebooks: They are moving to even higher resolutions and becoming more power efficient. Sharp showed a LG showed a 7 inch x Tablet display and a larger 14 inch x display.

Samsung showed two Samsung also showed a larger and impressive x Ultra High Definition x 4K TVs are especially impressive when displayed on very large screens. They are now bright enough and large enough to be used in storefront windows in direct sunlight to entice you to go inside with their colorful changing and animated content, which is much better and more effective than existing printed signs.

The LG and Sharp displays are both extremely bright at 2, nits, more than 5 times brighter than most Smartphones. LG showed a 47 inch x digital signage LCD display that is also designed not to degrade or blacken due to the heat from direct sunlight, which can affect some LCDs.

Sharp showed their large 60 inch x Digital Signage display. LG showed a 47 inch x transparent interactive digital signage display with a touch screen acting as a refrigerator door. You can see the refrigerator contents inside and can touch the screen door for more product information on the contents, or presumably to dispense the product in a vending application.

With Sub-Pixel Rendering the individual Red, Green and Blue Sub-Pixels are treated as independent addressable image elements and are not all bound together into specific Pixels.

In some cases Sub-Pixel Rendering can make the screen appear to have up to 3 times the resolution of Pixel Rendering. So the question is how will it compare with the iPad 2, and especially now with the equivalently priced much higher resolution new iPad 3?

I ran the Safari Browser on all 3 displays and compared them side-by-side using the New York Times website front page with its small text. All 3 displays have the same 5.

The Windows ClearType p display on the Asus Netbook was significantly sharper than the iPad 2 p display but also significantly less sharp than the new iPad 3 p display.

It is certainly possible that the Microsoft Surface RT Tablet will perform better than the Asus Netbook, but it is very unlikely that it will turn out to be visually sharper than the new iPad 3. On the other hand the Windows Pro version of Surface will have a x PPI screen, and it is quite possible that it will be comparable in sharpness to the new iPad 3 with x PPI.

It will be really interesting to compare them all Sharpness is only one aspect of display image quality. Goals and Predictions for the iPhone 5 and All 1st Tier Smartphone Displays The display will play a central role in the marketing, appearance, and performance of the iPhone 5, which will be announced on Wednesday September The iPhone 4 Display is no longer state-of-the-art.

While I don't have any inside information about the iPhone 5 display, below are a series of Sherlock Holmes deductions based on existing information and trends from the iPhone 4 and the latest competing Smartphone displays.

The iPhone 5 will need to meet most of these Goals in order to retain its Number 1 Ranking. The Aspect Ratio screen width divided by its height for the iPhone 4 is 3: For the iPhone 5 the Rumor Mill has settled on This looks like an excellent bet, so we'll work with that The current iPhone 4 Screen Resolution is x pixels.

In order to maintain compatibility with existing Apps the iPhone 5 can't stray too far from this. Since the Aspect Ratio is increasing from 3: In that case the Screen Resolution will be x pixels.

That's more vertical pixels, so existing Apps expecting x will simply be Letterboxed with 88 pixel black borders on the top and bottom. But since we are already Letterboxing, why not raise the pixel base up to pixels and add 40 pixel black borders there as well?

So PPI cannot be used by itself, but must be used together with the Viewing Distance in order to draw any conclusions about visual sharpness, and whether or not it qualifies as a Retina Display.

To be a Retina Display down to a viewing distance of Using PPI, the screen would be 4. Finally, with a resolution of x and PPI the screen would be 4. So there is lots of room for a Smartphone Retina Display up to 4.

Most Smartphones are used in reasonably bright ambient lighting. Reflections from the screen not only decreases picture quality but it makes the screen harder to read and causes eye strain. We measured the iPhone 4 Reflectance at 7.

The current record holder is the Nokia Lumia, with a screen Reflectance of 4. The iPhone 5 needs to do a lot better Reflectance under 5 percent. Contrast Rating for High Ambient Light: The Screen Reflectance together with the Screen Brightness determine how easy it is to see the screen under high ambient lighting.

This article has screen shots of 9 displays from 0 lux up to 40, lux ambient lighting - watch how they each degrade as the Ambient Lighting increases. Contrast Rating for High Ambient Light over The Color Gamut is the range of colors that a display can produce.

The iPhone 4 has a Color Gamut of 64 percent of the Standard, which produces somewhat subdued colors. The new iPad 3 has a virtually perfect 99 percent of the Standard, so we expect the iPhone 5 to follow suite.

A widely held and exploited misconception is that the bigger the Color Gamut the better - but it isn't A display with a larger than percent Color Gamut cannot show colors that are not in the original content - it just exaggerates and distorts the colors.

Unfortunately many of these Display Specs are misleading and are misunderstood by both consumers and professionals. This makes it harder to figure out which displays really are better. Below are many of the Display Specs you'll see together with brief explanations that will help you understand what they actually mean.

This Spec sounds straight forward - it's just the length of the screen diagonal. True, but that doesn't actually tell you how big the screen really is. What really matters visually is the area of the screen width times height and that changes significantly faster than the diagonal size indicates, so you'll either over or under estimate the true visual screen size based on just its diagonal size.

To get an idea of the screen area, square the diagonal size multiply it by itself on a calculator and use that for comparison. For example, a 7 inch Tablet actually has less than half the area 49 of a 10 inch Tablet There's more - the area also depends on the shape of the screen, which is another Spec called Aspect Ratio below.

Lower Aspect Ratios have larger screen areas for the same diagonal size. For example, a 10 inch 4: If you're not handy with this math, you'll often see the actual screen width and height listed in the Specs - multiply them on your calculator to get the area.

The Aspect Ratio is the screen width divided by its height and it's the Spec used to indicate the shape of the screen. It can be described as a ratio like 16 by 9, or numerically by dividing the two, 1.

For all consumer displays you can also get the Aspect Ratio by dividing the screen's listed horizontal and vertical Pixel Resolution - dividing by is also 1. While that's often called "Widescreen" most Widescreen movies have Aspect Ratios much larger than Another common Aspect Ratio is 4: This Aspect Ratio is better for reading in either Landscape or Portrait modes, but not as good for viewing Widescreen content.

The iPad has a 4: Other common Aspect Ratios are 5: As a result of Apple's Retina Displays, Pixels Per Inch is a very hot Spec - it's one of the most closely followed display Specs, but it's also one of the most misunderstood.

While the iPhone 4 has an impressive PPI, it is typically held relatively close and viewed from around 12 inches. A display with a larger Color Gamut cannot show colors that are not in the original content - it just exaggerates and distorts the colors.

A smaller Color Gamut produces subdued colors, and too large a Color Gamut produces over saturated and even Gaudy colors. That's why a smaller Color Gamut is visually better than too large a Color Gamut.

It's an indication that the manufacturer or reviewer is way out of touch. But it doesn't mean what most people think it does - a larger number of Colors does NOT mean a larger Color Gamut - it is merely the total number of possible combinations of the Red, Green and Blue primary color intensities.

There is also lots of duplication - for example, pure Red counts as Colors. Not all displays can produce 16 Million Colors - you'll sometimes see, Colors, and some that claim 16 Million Colors can't directly produce them - more on that under bit and bit Color, below.

Billions and Trillions of Colors: Some display Specs list Billions and even Trillions of Colors, which as explained above does not indicate a larger Color Gamut, but rather is just the total number of intensity combinations produced by the primary colors.

What happens is those displays process the image internally using 1, or more intensity levels. When you multiply this out as above you get Billions up to Trillions of intensity combinations, which sounds very impressive.

But this Spec is misleading and visually useless for two reasons: If you see a Spec listing Billions or Trillions of Colors consider it meaningless marketing puffery As mentioned in 16 Million Colors above, the Spec for the number of Colors is actually just the total number of possible intensity combinations for the Red, Green and Blue primaries.

For 16 Million Colors, each primary color needs intensity levels, which is 8-bits in binary. Since there are 3 primary colors and each has 8-bits, they add up to bits.

That's called bit Color and you'll sometimes see this Spec listed instead of 16 Million Colors. Some lower performance displays can only produce 64 intensity levels, which is 6-bits per primary and adds up to bits.

That's called bit Color and it produces only, Colors. But the real problem is actually the smaller number of 64 intensity levels, which often introduces visually noticeable discrete steps into images that have smooth variations in intensity - from faces to the sky - it's called False Contouring.

This effect is often masked by using two methods of Dithering: A word of caution: It's possible to detect the Dithering on images with close visual inspection. The Spec seems to imply that unless you are watching from a ridiculous 5 degrees from the edge of the screen you will see a perfectly fine image on the screen.

This Spec is nonsense and very misleading because it is defined for the angle where the Contrast Ratio below falls to an abysmal Viewing from other than the face-on center sweet spot generally decreases image and picture quality for effectively all displays.

So, the Standard Viewing Angle Spec is useless. The best way to evaluate it yourself is to look at a fixed frozen moderately colorful image or photo and see how the image changes as you shift your viewing position.

Contrast Ratio is the Spec that tells you how good the display is at reproducing relatively dark content, particularly at or near black. It is measured in an absolutely pitch black Lab.

It is very important if you watch movies with dark content under low Ambient Lighting. It's not so important if you are watching in bright Ambient Lighting like for many HDTVs and most mobile devices or when watching ordinary television shows and sporting events because they have almost no dark content.

Dynamic and Mega Contrast Ratios: You'll often see displays advertised with Contrast Ratios from 20, up into the Millions. The word Dynamic may or may not appear.

This Contrast Ratio is calculated by using the maximum Peak Brightness from one image with the minimum Brightness from a different image that has a darkened Backlight - so it doesn't apply to any actual single image, which makes it very misleading, especially when the word Dynamic is left out.

The true Contrast Ratio is what you actually see on any single image. The best LCDs have true Contrast Ratios of around 2, and the best Plasmas around 5,, so ignore values much larger than that as marketing puffery.

This is another over-hyped Spec that is a prime example of marketing wars fought with misleading numbers. LCDs sometimes produce visible Motion Blur because the Liquid Crystal the LC in LCD can't respond fast enough from video frame to frame when images change quickly due to motion, resulting in a blurred image.

Standard video content is updated 60 times per second, so a new frame is transmitted every 17 milli-seconds. It felt hollow, thin, and plasticky. It made noise when your fingers hit it to type.

Not this new iPad Pro. The screen feels rock-solid, and your fingers type silently. Also, the Air's loud, clicky Home button has been replaced by a luxuriously quiet one with Touch ID fingerprint authentication.

And I love that you can now summon Siri with your voice--no need to reach for the iPad Pro and hit a button unless you want to. For those wondering if this is good laptop replacement Artists will love what they can do with the Apple Pen.

However, even with a keyboard, productivity pales in comparison to a nice PC Ultrabook which can also feature a touchscreen, pen input, and fingerprint authentication or MacBook.

The iPad shines as a consumption device, not so much as a productivity device. Games and apps will keep getting more and more futuristic due to Apple taking the lead in Augmented Reality.

And those front and rear cameras There's one more thing The iPad is so easy to set up and get going, they don't even include an owner's manual. You could thoroughly enjoy the device for years without reading one sentence of instruction.

DON'T make that mistake. There is indeed an owner's manual, and it's hundreds of pages long. If you really want to see how magical your iPad Pro can get, open the iBooks app, do a search for "iPad User Guide for iOS11," and download the free manual.

Even something as small as the section on the many ways you can use the onscreen keyboard is priceless, but there's a massive amount more. Comment people found this helpful. Was this review helpful to you?

The last time I've owned an Apple product was in when I bought the iPad 2 which I sold a year later, however, I do use a 27" iMac at work, so I have some experience with Apple products.

I've wanted to get into digital drawing more, and wanted to buy a tablet that would let me do so while on the go. After extensive research, and going hands-on with a ton of devices when I could, my final 4 choices were the Galaxy S3, the Galaxy Tab A I almost immediately discounted the Tab A, as it's simply-HD screen, while looking good color-wise, simply did not cut it resolution wise.

It also has a So then I thought the S3 would fit the bill. Sure, it's a little pricey, but it's such an improvement on the Tab A. Beautiful screen, well-crafted, and it has the Android OS I know and love.

But the S Pen still didn't feel right to me, in weight and length, and the screen was a bit small. Then the surface pro. The surface pro is a great machine, but I just didn't get the feeling of a great experience using Win 10 on a mobile device.

And if I wanted to get the non-mobile processor variations, I was looking at forking over a lot more dough. So over the weekend, I decided to check out the iPad pro. For what I want it for, there's no comparison.

For people to say otherwise is silly. The screen is absolutely unbelievable, and the lack of latency with the Apple Pencil is like drawing on paper, it just feels so good in my hand.

The build quality is impressive, and I can't believe how light the device is. The speakers are a joy to listen to as well. It was tough deciding on whether or not to get the If I decide I need the extra screen real estate, I'll pick up the next generation Rose Gold Verified Purchase.

Love the size I downsized from the I can even put in my purse yet it's display is a great size. Comment 51 people found this helpful. This is the 2nd iPad that I own, the first being the original mini.

Decided to upgrade because I started a masters program and I need to take notes etc and the fact that the mini is missing a good portion of its screen due to countless falls even though it's still going strong.

I expect the same quality that apple is known for. For those of you who own numerous apple products, set up was a breeze and compatibility across all devices is freakishly smooth.

The only inkling of an issue that I have thus far is the size of the iPad as I'm used to the mini. Even though I have big hands, typing is sometimes tiresome but I have my MacBook Air for serious writing.

For 16 Million Colors, each primary color needs intensity levels, which is 8-bits in binary. Since there are 3 primary colors and each has 8-bits, they add up to bits. That's called bit Color and you'll sometimes see this Spec listed instead of 16 Million Colors.

Some lower performance displays can only produce 64 intensity levels, which is 6-bits per primary and adds up to bits. That's called bit Color and it produces only, Colors. But the real problem is actually the smaller number of 64 intensity levels, which often introduces visually noticeable discrete steps into images that have smooth variations in intensity - from faces to the sky - it's called False Contouring.

Contrast Ratio is the Spec that tells you how good the display is at reproducing relatively dark content, particularly at or near black. It is measured in an absolutely pitch black Lab. It is very important if you watch movies with dark content under low Ambient Lighting.

It's not so important if you are watching in bright Ambient Lighting like for many HDTVs and most mobile devices or when watching ordinary television shows and sporting events because they have almost no dark content.

Dynamic and Mega Contrast Ratios: You'll often see displays advertised with Contrast Ratios from 20, up into the Millions. The word Dynamic may or may not appear. This Contrast Ratio is calculated by using the maximum Peak Brightness from one image with the minimum Brightness from a different image that has a darkened Backlight - so it doesn't apply to any actual single image, which makes it very misleading, especially when the word Dynamic is left out.

Standard video content is updated 60 times per second, so a new frame is transmitted every 17 milli-seconds. In principle, the Response Time measures how quickly the display responds in milli-seconds.

It's important to make that number a lot smaller than 17ms milli-seconds. A lot of advanced technology has gone into improving the hardware Response Times, but also a lot of advanced marketing has gone into improving the published Response Time Specs, with the values falling precipitously from 8ms, to 4ms, to even 1ms.

Using high speed screen shots in this article we demonstrated that the true objective Response Times are actually considerably longer than 30ms. So the Response Time Spec is mostly meaningless marketing puffery In principle, the higher the maximum Brightness Spec the better, but people often set the screen Brightness too high, which causes eye strain and wastes power and reduces battery running time.

The optimum screen Brightness varies with the current level of Ambient Lighting. Many displays have Automatic Brightness controls that should appropriately adjust the screen Brightness, but we have found them all to be functionally useless as explained in this article.

High Screen Brightness is only useful when you need to look at the screen under high Ambient Lighting. But under these circumstances the Reflectance of the screen is actually more important than the screen Brightness because it washes out the image, and you generally see reflections of your face and the area behind you, which is distracting and causes eye strain from involuntarily focusing on them instead of the screen content, which is much closer.

Contrast Ratios above are measured in the dark and are only relevant for displays viewed in low Ambient Lighting. As the Ambient Lighting increases the Screen Reflectance becomes a dominating factor and the Contrast Ratio becomes increasingly irrelevant.

It is based on Brightness and Reflectance Lab measurements that accurately indicate how well a display performs in high Ambient Lighting. This article includes the Contrast Rating, Lab measurements, and screen shots for 9 Tablets and Smartphones for Ambient Lighting levels up to 40, lux.

Anti-Glare or Anti-Reflection Treatments: Many displays list within their Specs that they have Anti-Glare or Anti-Reflection properties, but most of the time it's a vacuous statement.

Our Lab tests show that there is a tremendous 3 to1 range in Reflectance between many popular Tablets and Smartphones. This article has the Lab results plus Screen Shots showing how the screens of various Tablets and Smartphones degrade under high Ambient Lighting levels up to 40, lux.

The Google Nexus 7 is the first of the second generation 7 inch Tablets out of the gate The published display specs look pretty good, and some of the basic Lab measurements also look pretty good.

But just like in Triple Crown races, an important but overlooked issue can spoil the outcome. In this Display News item we'll explain what went wrong with the Nexus 7 display - the details will appear in our upcoming in-depth 7 inch Tablet Display Shoot-Out.

The display on the Nexus 7 sounds great on paper - a x display with Pixels Per Inch, within the PPI sweet spot we have recommended for Tablets, so text and graphics appear very sharp, but not as sharp as on the new iPad 3.

Its display Contrast Ratio is about 1, which is excellent for mobile displays. So far so good Next we measured the Color Gamut, something where almost all mobile LCDs come up short in order to improve power efficiency and battery running time.

They typically provide only about 60 percent of the ideal Standard Color Gamut, which results in somewhat subdued colors in all displayed images, including photos and videos.

For the Google Nexus 7 we measured an impressive 86 percent of the Standard Gamut - not as good as the new iPad 3's 99 percent, but much better than most existing LCD Tablets and Smartphones.

So far, it sounds really good - but let's see how good it actually looks Even before I examined the display with our DisplayMate diagnostic test patterns I knew something was seriously wrong when I looked at the first of many sets of standard photos that we use to visually evaluate displays.

Normally we compare everything to a calibrated professional studio monitor to check for image and color accuracy. But that wasn't necessary with the Nexus 7 because many of the images were noticeably washed out - they looked like over exposed photographs with missing highlights, reduced image contrast, and weak colors.

However, darker images look a lot better than brighter ones, which actually tells us a lot about its cause So, what's the problem? The Intensity Scale often called the Gray Scale is way off.

The display's Brightness fails to increase sufficiently for bright image content, causing bright image detail to be compressed and lost. See the Figure at left for the Nexus 7 and this Figure to see what the Intensity Scale should look like.

There is about a 25 percent compression of bright image content, which is quite substantial. This holds for both the Gallery Viewer and the Chrome Browser. On some cheap displays this is done intentionally by the manufacturer because the compression actually makes them appear artificially bright.

Here I think it's probably just incompetence by the manufacturer, which is too bad because they messed up a really nice display. Depending on the display firmware this may or may not be correctable with a software update.

These tests were made under Android 4. Looks like Google didn't pay enough attention to the Steve Jobs memo that the key to a successful Tablet is an outstanding display. If high image and picture quality is important to you, then you might want to skip the Google Nexus 7 and wait for a Tablet with a better display, or wait and see if Google can correct the problem Although the Nexus 7 has a high quality display, they messed up the factory calibration.

This affects all displayed images, but it is most noticeable on any form of photographic image, including videos, because the color and intensity mixtures are visually critical for them to look right.

On the other hand, for high contrast software generated text and graphics the display will look fine. In short, the display produces washed out images and colors in spite of the fact that it has a display with excellent color saturation and contrast.

We'll provide all of the details in our upcoming 7 inch Tablet Display Shoot-Out. We're now waiting for the rumored Apple mini iPad and the rumored new Amazon Kindle Fire - the rumor drums are beating very loudly so we are expecting a Shoot-Out very soon That is why you take a standard vision test at 20 feet and aren't allowed to walk right up to the chart and read the smallest letters on the bottom line - visual acuity depends on the viewing distance.

If the display were any sharper with a higher PPI or higher pixel resolution your eyes wouldn't be able to see the difference. That is what "Retina Display" means The new iPad 3 and MacBook Pro have much lower PPIs than the iPhone 4 but Apple correctly markets them as Retina Displays because they are typically held further away from the eyes and therefore still appear "perfectly" sharp at their proper viewing distance.

On the other hand, the average viewing distance for living room HDTVs in America is around 7 to 10 feet, depending on the screen size. If the HDTVs had a higher PPI or a higher pixel resolution your eyes wouldn't be able to see the difference at their proper viewing distances.

Some manufacturers are introducing HDTVs with resolutions that are at least double the existing standard x resolution - x or more. They are often called 4K displays. However, the higher resolutions are important for Digital Cinematography and cinema projectors that have large 10 foot or more screens.

But note that there isn't any consumer content available yet for resolutions higher than x, so save your money and wait for the Apple Television with a true x Retina Display If you leave a bright static image up for a while and then switch to a uniform dark gray image you may see a ghost of the static image that may take up to 5 minutes to disappear.

This is not peculiar to IPS displays as some news reports have claimed. We've been testing for this effect for over 15 years and have seen it in all sorts of display technologies, including LCD, Plasma, and even CRTs - our DisplayMate products have specific test patterns to look for ghosting and image retention.

In some cases it can take hours for the ghost to completely disappear. The ghost can be either a positive or negative image, and either color or monochrome depending on the cause. It used to be much more common, but now it's unusual to see it in a display.

Depending on the cause it can be better to leave the display on with a dark uniform image, on with a bright uniform image, or turn the display off all together. This is most likely a start-up production problem that may already be fixed.

It's brilliant and has made all other existing Tablets and Laptops obsolete. We'll see how long it takes other manufacturers to learn how to improve their display performance - Contact DisplayMate Technologies to learn how.

While we are not planning on publicly reporting display test results for the new MacBook Pro Retina Display, here is some analysis and commentary: That is Apple's criterion for a Retina Display not the actual resolution of the Human Retina, which is about twice as high.

Since the typical viewing distance for a display this size is 18 inches or more the MacBook Pro is comfortably in Retina Display territory The x resolution display has 5. That's an incredible number of pixels - your much larger HDTV has only 2.

Text and graphics will appear amazingly sharp. Color Gamut and Accuracy: While the enhanced screen resolution is getting most of the attention, Apple is also announcing "richer and more vibrant colors" for the MacBook Pro Retina Display.

Good color is what gives a display its real Wow factor. But color needs to be done carefully for accuracy and not excessively into gaudiness as with many existing mobile displays.

The new iPad 3 did an amazing job with color accuracy and picture quality - our new iPad 3 Lab Tests showed that it is more accurate than any display unless it is a professional display that has been professionally calibrated.

The MacBook Pro Retina Display should have the same incredible accurate calibration, colors and picture quality so that everything including photos, TV shows, movies, and videos will all look exactly the same on all latest generation Apple devices.

I've speculated in an earlier Display News piece that this how the Apple Television will be marketed to consumers and why it will be successful Traditional high PPI displays with amorphous Silicon are inefficient with both brightness and power.

How can this be? You may recall that IGZO technology has been making headlines for months, first rumored to be the technology used in the Retina Display for the new iPad 3. IGZO is significantly more efficient than amorphous Silicon.

Just in time for the MacBook Pro Less Reflections and Reduced Glare: I have been making a big deal about Screen Reflectance since - all of my Mobile Shoot-Out articles include Lab Measurements of total and mirror reflections from displays.

So I'm glad that Apple is now making this a marketing issue. This lowers the Screen Reflectance like on the iPhone 4 but it's more difficult and expensive to manufacture and a lot more expensive if you crack the screen.

Apple is claiming a 75 percent reduction in Glare, which is one form or another of Reflectance. That is a factor of 4 reduction to 25 percent Reflectance of previous models.

I find that 4: No surprise here - the LG ppi display looked amazingly sharp from inside its glass case at the SID show. Very bright too - nits, brighter than most mobile displays but this display was not battery powered.

One surprising technical note is that the display shown at SID uses traditional amorphous Silicon, which is not particularly efficient with brightness or power at high PPIs, and is the same technology used in the new Apple iPad 3.

Of course, one question is do you need a ppi display? For some content you will need a magnifier to read any fine text and graphics designed for viewing on larger screens. One major advantage of this format in a Smartphone size is that there is a tremendous amount of content designed and formatted expressly for x HDTVs that can be displayed exactly without requiring rescaling to lower resolutions, which always introduces scaling artifacts.

So the x screen format will make the images very crisp and also save processing time and power, since the images can be passed unaltered to the display. A display like this will require lots of battery power for the CPU, GPU, memory, and Backlight, so it remains to be seen how widely adopted it will be for mobile devices in the near future.

And if you have read any of my Display Shoot-Out articles you know that I am a tough grader for displays and don't readily hand out compliments for displays. On the flip side, this was a prototype unit and I was watching a manufacturer's demo - and all good demos are finessed to be seductive - and I admit to being seduced at the show.

But in our DisplayMate Labs and Shoot-Out facilities everything is objective and we have our own suites of test patterns, test photos, test videos, and instrumentation, plus I become just like Mr.

Spock, incapable of being swayed or seduced by human emotions So I am looking forward to testing a production unit later this year The larger Color Gamut will also allow the TV to compensate for the loss of color saturation at high ambient light levels - we'll see if LG adds that functionality.

Ordinarily I don't like White sub-pixels because they are used to artificially increase image brightness at the expense of color saturation and accuracy. It all depends on the color management strategy and most manufacturers do a poor job of it.

LG assured me that they are mindful of this issue and that the primary function of the White sub-pixels is for producing bright white backgrounds for Apps and internet applications with text.

Although the Screen Reflectance was relatively low, it was still a giant mirror and I could see everyone watching the TV in the booth whenever the images were dim or black. To be fair the TV was in a brightly lit area of the show and most people that buy an expensive high-quality TV like this one will put it in a home theater with controlled or reduced ambient lighting.

A glossy mirror-like screen is fantastic for watching in total darkness, but very few people do that, and it's even dangerous as you can run into things when you get up The running demo was mediocre and that might be the source of the problem.

The Samsung 2D OLED TV was in my opinion horrendous because its color saturation was turned up so high that it was beyond gaudy and into visually repulsive territory in my opinion. Samsung has this thing about flaunting color saturation rather than flaunting color accuracy.

They make excellent state-of-the-art display hardware, but when it comes to calibrating their own products they degrade the picture quality and accuracy with exaggerated marketing features and effects that are designed to make them stand out scream in stores and in marketing materials.

To prove my point, the new Apple iPad 3 has a Samsung display that is perfectly calibrated by Apple and produces better picture quality and accuracy than any Samsung branded product that I have ever seen.

See my predictions for the Apple Television below Like every other new technology the manufacturing costs and retail prices will fall over time. But that will take years Sherlock Holmes Predictions for the iPhone 5 and Apple Television I was hesitant about writing this piece because of guilt by association with all of the idiotic rumors circulating about the iPhone 5 and Apple Television.

This article is different because it is based entirely on Sherlock Holmes logical deductions from facts that are in plain view for everyone. The iPhone 4 and iPad 2 have displays with identical photometry and colorimetry so images on both models appear visually identical except for pixel resolution and pixels per inch.

This is not an accident but results from a very careful systematic factory display calibration. The new iPad 3 has a much improved virtually perfect factory display calibration that produces the most accurate images and colors of any consumer device that we have ever tested.

See my new iPad Display Shoot-Out. Again, this is not an accident The iPhone 5 will have photometry and colorimetry that is identical to the new iPad 3 in the same way that the iPhone 4 and iPad 2 are identical.

Again, this is not an accident, but will be the basis of a major strategic decision by Apple. Starting with the new iPad 3, images on all future Apple devices and displays will appear visually identical and with extremely accurate colors and images.

Why this is Important: The devices from every other manufacturer are not only inaccurate and different but also inconsistent from device to device and model to model. This is especially bad when people have multiple devices and are sharing personal photos with family and friends because everyone wants to be sure that they look just as good to everyone else as they do on their own devices.

Right now that is definitely not the case Why Apple will Introduce an Actual Television: Because all existing TVs produce inaccurate and inconsistent colors and images that will be poor matches to Apple's own iPhones and iPads.

Photo sharing is especially important and convenient on WiFi and internet connected TVs. Why an Apple Television will be Very Successful: Consumers will love the fact that everything including their personal photos, TV shows, movies, and videos will all look exactly the same on all Apple devices.

Plus if Grandma also has an Apple Television then she'll see photos of the family exactly as they appear on your own iPhone, iPad, and Apple Television - and she'll know that her photos will look exactly the same on your Apple Television as on hers.

And that's why consumers will flock to Apple Televisions. This is all based entirely on Sherlock Holmes logical deductions. I am leaving this article up permanently for the record More and more people have polarized sunglasses and they can significantly interfere with seeing the display - the screen can become invisible and just appears entirely black.

Of course all of this should only matter outdoors, although movie stars and an increasing number of regular people also wear sunglasses indoors, so be careful and check before you buy With polarized sunglasses all iPads go black in Portrait mode.

Other LCD displays go black in Landscape mode. Much better is for the manufacturer to set the extinction angle for 45 degrees orientation so that the display looks good in both Portrait and Landscape modes.

Best of all, manufacturers can add compensating film layers to the display that make this effect go away almost entirely by converting to Circular Polarization.

The iPhone 4 and Samsung Galaxy Tab Between all the other models, the upgrades were incremental. A few more features, a tiny bit less weight. The nearly four-year gap between my Air and the Pro was the longest, and the difference is astonishing.

This iPad is freakishly fast. There's no lag to anything--changing screen orientation, opening apps, working, watching videos, whatever. It's the smoothest touchscreen device I've ever owned.

The screen is just gorgeous. The True Tone display automatically provides the correct and most eye-pleasing color temperature for any lighting. The screen is a fraction of the reflectivity of my iPad Air, making for a far better reading experience.

Also, there was one thing I hated about the iPad Air, which was a downgrade from previous models: It felt hollow, thin, and plasticky. It made noise when your fingers hit it to type.

However, even with a keyboard, productivity pales in comparison to a nice PC Ultrabook which can also feature a touchscreen, pen input, and fingerprint authentication or MacBook.

The iPad shines as a consumption device, not so much as a productivity device. Games and apps will keep getting more and more futuristic due to Apple taking the lead in Augmented Reality.

Even something as small as the section on the many ways you can use the onscreen keyboard is priceless, but there's a massive amount more. Comment people found this helpful.

Was this review helpful to you? The last time I've owned an Apple product was in when I bought the iPad 2 which I sold a year later, however, I do use a 27" iMac at work, so I have some experience with Apple products.

For people to say otherwise is silly. The screen is absolutely unbelievable, and the lack of latency with the Apple Pencil is like drawing on paper, it just feels so good in my hand. The build quality is impressive, and I can't believe how light the device is.

The speakers are a joy to listen to as well. It was tough deciding on whether or not to get the If I decide I need the extra screen real estate, I'll pick up the next generation Rose Gold Verified Purchase.

I expect the same quality that apple is known for. For those of you who own numerous apple products, set up was a breeze and compatibility across all devices is freakishly smooth.

This iPad is awesome. Its so bright, clear and fast. This product is so impressive that I am going to get one for myself!!! Comment 8 people found this helpful.
