Can confirm. Using (3) different mdp-to-vga adapters
- on 4.1.13 my external monitor is not recognized and does not work, xrandr
returns some garbage output and/or freeze the whole system until i unplug the
monitor
- on 4.2.6 monitor is recognized correctly but the resolutions supported are
all wrong (not even the same scale, 4:3 vs 16:9), no way to make it use the
correct ones (like lost 1-2 hours testing everything I could)
- on 4.3.0 all works flawlessly and without any problem, no need to configure
anything: as soon as the monitor is plugged in it uses the correct (max)
resolution
