I just installed UMate for my Raspberry Pi 3 B+ and I'm using a Samsung S220D300HY monitor. However, it is not recognized and instead of the 1920X1080, I've got 1824X984. Any idea how I can get my Pi to see the Samsung and give me the full resolution?
Add the following entry to cmdline.txt:
video=1920x1080
Uncomment 'disable_overscan=1' as well in config.txt.
