Pixel 8 and Pixel 8 Pro display specs are different than you think
Android Authority has received information on the screens that will be utilised on the forthcoming Pixel 8 and Pixel 8 Pro devices from a source inside Google. This info actually reconfirmes previously disclosed specs from highly reliable tipper Ross Young from Display Supply Chain Consultants (DSCC). For the forthcoming device, Google is downsizing the Pixel 8 display from the 6.31-inch panel it used on the Pixel 7 to 6.17 inches, that's actually a big thing considering the Pixel 7a is also having the same screen size but one big upgrade is that the refresh rate has increased from 90Hz to 120Hz, however the 1080 x 2400 FHD+ resolution will remain the same.

From a 1000 nits to 1400 nits in HDR mode is gonna be another big improvement. The smaller display actually means the pixels per inch (PPI) is 427 up from 417.
Changes are being made to the Pixel 8 Pro screen. For the Pixel 8 Pro the curved panel is going away rather you will see a flat panel. The curved display of the Pixel 6 Pro and Pixel 7 Pro has drawn criticism, and some users seem to have preferred that the curves disappear.
The Pixel 8 Pro's display is also getting a slight trim, going from 6.71 inches to 6.70 inches. The Pixel 8 Pro's resolution decrease from QHD+ 1440 x 3120 on the Pixel 7 Pro to 1334 x 2992 is what most people find surprising in this situation. Despite the fact that most people wouldn't notice the change, this reduces the PPI from 512 to 490. As opposed to the pixel 7 pro's 1000 nits, HDR content can now be seen at a maximum brightness of 1600 nits.

In contrast to the Pixel 6 Pro and Pixel 7 Pro, the Pixel 8 Pro will still have a 120Hz refresh rate, but the screen will be able to redraw between 60 and 120 times per second more seamlessly. The Pixel 8 pro will be able to better adapt the refresh rate(0, 30, 60, and 120 Hz) with the information displayed on the screen because the refresh rates for the two previous Pixel Pro versions were fixed (30 Hz, 60 Hz, and 120 Hz).
According to the source, Google doubled the corner radius on the screens of both phones, making the edges more rounded and less squared off. The insider also mentioned that Google will purchase the Pixel 8 Pro's screen from Samsung, much like it does with the Pixel 6 and Pixel 7 models. The Pixel 8 series should debut and be on sale in October.
