My Tinker Board is hooked up to a Benq 24″ monitor running with a 1920×1080 resolution. On this monitor, Android’s icons and font are too chunky for me, wasting screen real estate. Asus’ Android image is configured to use 240 DPI. Here’s a very simple way to make better use of the screen real estate by reducing the DPI, making icons and fonts appear smaller. After some experimentation, I’m pretty satisfied with 160 DPI.
