I would check that the EDID from the monitor reports support for the mode you are
setting.

You can get EDID from xrandr —verbose I recall, and use an edid decode program to view the
details. It been a while since I had to do this and no not recall the exact program to
use.

Also check in dmesg for any messages about edid problems.
