HDMI port offset slightly down on HDMI LCD

Ok, so ive been throwing myself at this for three days now, and thought id give up and phone a friend(s)

My HDMI output is offset 5ish pixels down on ANY LINUX DISTRO i install on this SBC, with this display only. On my other, larger monitor, it works fine, but on this one, the lowest 5-10 pixels are cut off, and there is a blank bar(that responds to certain animations, so some kind of visual signal is being sent)

Connecting my main PC(EndeavourOS on a desktop) to the Waveshare screen does NOT have this issue.

Tried the official RADXA image, Armbian-Debian, Armbian-Ubuntu, and Manjaro-ARM. All four have the exact same issue.

Tried offsetting the screen with Xrandr and Kscreen-Doctor, but neither seemed to work.

The OSD on the monitor does not help, I have checked all options there.

Please let me know any useful information or ideas you might have, OR what information you need from me to help further.
