1.2m display port

any idea why this is happening?

provide some screenshots of before & after so we can see what is actually happening.
upload images to IMGUR and then link them here with the 'Insert Image (Ctrl+P)' option.

When I screenshot, both 120hz and 144hz look fine, but what i see is the picture i uploaded

odd that screenshots wouldn't show the issue but first-person view does.
has it always been this way or a recent issue that has arisen?

i would guess it is a faulty display that can't handle the max refresh rate.

but have you looked through the monitor's OSD menu for any 'overclock' options.
many displays have to have this sort of feature enabled for them to reach maximum rated refresh rate.
my previous 165Hz AOC AG271QG was this way. without the overclock feature enabled it also maxed at 120Hz.

have you also checked the AOC product support pages for any drivers that may be needed?

It started happening a month ago, but back then i would just switch to 120hz and when i change it back to 144hz it would be fine, but now my screen just goes half black whenever i change it to 144hz. I've gone through the OSD menu and no overclock option can be seen. And i have checked for drivers and have installed them but nothing changed

are you using the included cable, a known high quality brand, or some generic?
it could be low quality and over time can't handle the bandwidth.

but i would probably still contact AOC.
if it's a known issue they may have a simple fix or may offer replacement parts.
