A new command to me, interesting but what do I do with it?
If VGA-0 is connected(xrandr),
monitor-parse-edid /sys/class/drm/card0-VGA-1/edid
should show information about a monitor and its capabilities i.e. edid.
Note that there is a discrepancy in naming scheme between kernel(VGA-1)
and display server(VGA-0).
I assume it's the monitor from "Display rates" thread[1].
