Professional display review ranks the Samsung Galaxy Tab 10.1 screen at the top of popular tablets

Professional display review ranks the Samsung Galaxy Tab 10.1 screen at the top of popular tablets
We have been using the research of DisplayMate in our smartphone screens article, and were fascinated by the depth that this professional calibration shop goes to examine screen quality beyond the marketing gimmicks manufacturers often use.

Using stuff like "narrow collimated pencil beam of light" to measure such simple things as screen reflection, up to photometers and measurement of chromacity coordinates for the white-point color temperature, DisplayMate comes to a pretty accurate picture of what each display is capable of. For example, all of the examined five tablets had a narrow color gamut, ranging from 55 to 64% of the standard one, with the best coverage exhibited from Samsung's tablet.

What was found in the end is that the new PLS-LCD screen of the Samsung Galaxy Tab 10.1 beats the next best screen, the IPS-LCD on the Apple iPad 2 in slightly more categories, with the only hindrance being the oversaturated colors on Samsung's best tablet, whereas the iPad 2 actually came with too low of a color saturation. For the purist professional calibrator, it turns out, less saturation always beats gaudy colors. Not so with the typical user, though, people love them some flashy colors.

Coming in third was the Asus Eee Pad Transformer, again with an IPS-LCD display, followed by the Acer Iconia Tab A500. Last place is occupied by the Motorola Xoom's screen, largely due to obnoxious level of screen reflection, bad viewing angles and poor factory calibration settings.

The Viewing Tests examined the accuracy of

photographic images by comparing the displays

to a calibrated studio monitor and HDTV.

 

In side-by-side visual comparisons viewers rated the

iPad 2 and Galaxy Tab the Best overall,

the Asus Transformer “Very Good”

the Acer Iconia well below the above,

and the Motorola Xoom the “Worst.”

Dr Raymond Soneira from DisplayMate also lists some interesting observations regarding the screens, like: "all of these Tablets have an unsatisfactory Ambient Light Sensor and Automatic Brightness Control, which wastes battery power and causes eye strain". He also goes on to explain that while the iPad 2 has a 9.7" screen, whereas the others are 10-inchers, the Android tablets actually have 5% less real size at your disposal, due to the 4:3 aspect ratio of Apple's tablet, and the fact that the Android system bar occupies 48 pixels.

On the other hand, the 16:9 aspect ratio of Android tablets makes them ideal for watching movies, whereas the iPad 2 in portrait orientation comes very close to the aspect ratio of a regular A4 sheet of paper, making it more comfortable for reading content. As a downside of all the Android tablets, except the Samsung Galaxy Tab 10.1, Dr Soneira points out that in Android 3.1 the manufacturers continue to have 16-bit color in the photo gallery, processed to 24-bit, but with poor dithering.

Neat review, I'm surprised it was so close for some of the contenders, given the differing technologies at play.

Glad the Super-Size ipod didn't win.

As usual, you are wrong superfandroidevo.

I am not the one who cooks up mathematical equations just to contradict positive articles related to Apple devices. Sniggly and you do that a lot, not me.

This is a professional review. I may disagree with it based on my personal taste, but I will respect this article.
