Hi Glenn,
That first screenshot in comment #17 is most telling. It shows the BIOS
screen is rendered half right and half wrong. So given some of the
problems persist in the BIOS screen (when no OS is running) AND in
Windows 10, I think it's likely the screen is faulty and needs
replacing. But maybe we can still improve the Linux situation...
Next,
1. Please verify the problem occurs in both 'Ubuntu' and 'Ubuntu on
Wayland' sessions.
2. Log into a regular 'Ubuntu' session and run:
xrandr --verbose > xrandrv.txt
cat /sys/class/drm/*/edid > edids.bin
and attach the resulting files here.
3. Look in Settings > Screen Display and try selecting different values
of 'Resolution' and 'Refresh Rate'.
