Both the Nokia Lumia 800 and Nokia Lumia 710 have PenTile displays, but its use is less noticeable on the 3.7 inch screen on both handsets when compared to how it would have looked with the 4.3 inch display on the Lumia 900. The display on all three models has a resolution of 480 x 800. Nokia calls the display on all three models "ClearBlack" referring to the anti-reflective polarizer on the screen. Still, as the pictures show, the PenTile display on the Nokia Lumia 710 and 800 does not have the clarity and detail that will be found on the Nokia Lumia 900.
The use of the RGB subpixels on the Lumia 900 has been lost in the excitement of Nokia's introduction of the high-end phone and its upcoming launch on AT&T. In the end, the tweet from Nokia is good news for those looking to pick up the newest flagship model from Nokia.
