According to the Chromium code commits initially found by Reddit user -nbsp- , Atlas will power a 3840 x 2160 display. For comparison, the very detailed screen on the Google Pixelbook is 2400 x 1600, so we’re talking about quite a few more pixels: More than double.
Since the display size is unknown, it’s not possible to calculate the pixel density, or pixels per inch (PPI). But you can determine the aspect ratio, which is 16:9, or what you might consider a widescreen display. The Pixelbook screen uses a 3:2 aspect ratio, so it’s “taller” but not as wide as a 16:9 display.
Would this Chromebook actually run at full resolution though? Not likely, because for higher resolution devices, Chrome OS scales everything it displays. If it didn’t, standard text would be small and very difficult to read on a laptop screen capable of displaying nearly 8.3 million pixels.
