Steps to reproduce the problem:
1. Use any 1080p, 1440, 2160p display
2. Attempt to adjust DPI scaling
3. Changing resolution produces very blurry font rendering

What is the expected behavior?
Users should be able to change DPI scaling on Chromeboxes like on a Chromebooks.

What went wrong?
Chromebooks have the ability to use a device panel's fixed resolution and scale the UI.

Chromeboxes do not.

Did this work before? N/A

The only exception is 2x zoom for 2160p. Nothing, AFAIK, for any other resolution. I'd suggest at least 1.5x (1440p) should be available for 2160p.

The ability to set a fixed resolution scaling like with Chromebooks would probably be ideal.
