Beelink X2: setting HDMI resolutions from Android?

Until the day Armbian can auto-configure HDMI output (with respect to a TV or DVI computer monitor), the thought occurred to me that the Beelink X2 defaults to Android KitKat 4.x, and from there maybe it's possible to plug in the TF card that you'll be rebooting into, then access the card from Android to makes changes, like:

h3disp -m 720p60 -d 

If a DVI-monitor is expected to boot into. I was even brushing up on MIT App Inventor to make presets from Android side, but my skills drop off sharply at that point.

The practical reason for his, is not only to show the neighbors but also have a media player anywhere there's a screen.

In conclusion, I don't know what makes Android auto-resolve destination video resolution and type, but it would save a lot of fiddling if something similar is incorporated into Armbian images. 

Armbian otherwise is so amazing I'm grateful to the gentle geniuses.
