As the Chromebook market has evolved, the number of new screen sizes, resolutions, and aspect ratios has only increased. At this point, there are Chrome OS devices anywhere from 10-inches up to 15.6-inches, 720p to 4K, and everything in between. And that’s to say nothing of extended displays and Chromeboxes outputting to a vast variety of external monitors.
With all these variations in place at this point, Chrome OS requires the ability to actively scale the entire interface to work on different displays. Native 1080p looks pretty nice spread across 15.6 diagonal inches, but the same pixels squished into a 13.3-inch screen like the Pixelbook Go makes things quite small on screen.
