DisplayMate posted yet another interesting display shoot-out, this one testing Samsung's new QHD (2560x1600) Super AMOLED displays used in the upcoming Galaxy Tab S (8.4 and 10.5) tablets. As these displays are very similar to the GS5 display, it's not surprising that DisplayMate found those tablets to offer the best performing displays ever. This is yet another testimony to how great OLED displays are - and the rate of improvement in OLEDs is very rapid.

As DisplayMate found out, the Galaxy Tab S establishes new records for best Tablet display performance in: Highest Color Accuracy, Infinite Contrast Ratio, Lowest Screen Reflectance, and smallest Brightness Variation with Viewing Angle. These are also the highest resolution tablets at QHD.

Both tablets offer a brightness of 546 nits with automatic brightness on and 415 nits under manual brightness. This is very good, but the world's brightest tablet to date is Nokia's Lumia 2520 (684 nits). As the OLED screens offer record low screen reflectance, this means that its very efficient in high ambient light.

Interestingly, DisplayMate finds that while the 10.5" tablet uses an RGB strip architecture (where every pixel is made from red, green and blue subpixels), the 8.4", with the higher-density display (361 PPI) uses the company's Diamond Pixel matrix, the same one used in the GS5.

DisplayMate compared the tablets to Amazon Kindle Fire HDX (with its Quantum-Dots enhanced LCD) and Apple iPad Tablet Displays. As we said, the new OLED tablets were found to be superior to both Amazon's and Apple LCD displays.



Regarding the efficiency of those displays, if you scale the displays to the same brightness and screen area, DisplayMate found that the OLED Tab S 8.4 (Diamond Pixels) is 27% more power efficient (for the same screen size and Luminance) than the LCD iPad Air for mixed image content (that includes photos, videos, and movies, for example) with a typical 50 percent Average Picture Level. The OLED Tab S 8.4 is 32% more power efficient than the OLED Tab S 10.5 with its RGB stripe pixels.

Finally, DisplayMate also praises Samsung for implementing color management (this was introduced in the GS4). The new tablets offer four user selectable screen mode (including the Adaptive Display mode).

So - if you can't wait to own those tablets, you'll be happy to know that you can already pre-order the tablets on Amazon.com. Both tablets will ship on June 26 - the Galaxy Tab S 8.4 costs $399.99 while the larger Tab S 10.5 costs $499.99.

Now if they would only lower the pixel density and finally release a damn 30" monitor at that resolution! -_-

Even 20-24-inch 4K monitor for, say, 2000$ would be very nice.

30"+ is more like TV set, not a monitor.

Have you even checked out recent monitors?

24" monitors commonly have a resolution of 1920x1080, not 2560x1600.

That's why I said 30". It is around that size that 2560x1600 is common.

Also, it's very rare for a newly released monitor to be smaller than 24".
