Proper Display Scaling Likely Coming to Chrome OS in Chrome 65
With the release of the third build of Chrome 65 into the Chrome OS Dev channel, a new feature has popped up in settings that has big and positive implications for those who use their Chromebooks connected to an external monitor. The new settings is enabled with a flag setting, chrome://flags/#enable-display-zoom-setting which enables the ability to change how scaling is done on external monitors.
Currently with a Chromebook, if you connect it to an external monitor, especially a high resolution monitor, you end up with having to scale the display to be able to read everything. Usually this is 125% of normal to make things bigger and readable. Doing this effectively changes the resolution to something lower, thus you lose screen real estate.
