MacBook air inverts external monitor screen color

The actual monitor is a Planar PLL2210w

and it keeps inverting colors on a 2020 macbook air, works fine on a dell laptop i have, and a macbook pro also, its just on this, also i tried messing with the monitor settings, the different color settings either made the screen worse or wayyy too bright and at one point the left bottom corner just started glitching

i use a hdmi to ubs-c converter btw

this is what it looks like

this is what its suppose to look like

update

it does this cute thing where it will make white turn green then try to fix itself i guess, then anything that supposed to be white will start flashing between green and white for a few seconds ._.

idk if its the monitor, the laptop, or maybe the converter, and how do i fix it lol
