DELL S2421HN Monitor turns purple when switching to RGB input format

Hi,

I just did a fresh install of CachyOS and my monitor defaults to YPbPr input format and when i change it to RGB it gets a purple tint almost like a loose cable, but I tested it on another machine with Windows on it and it works perfectly on both ports. What could be the issue ?

Please, I don’t want to back to Windows. Assistance would be greatly appreciated.
