New 540hz monitor cant get to 1080p or above 60hz when plugged into my rx 7800xt

I recently bought a new monitor to be my new main one and my 3rd monitor, when I plugged it in I found that i could not get it to be 1080 p or go above 60hz (it is showing every single resolution up to 4k APART FROM 1080p) Thought maybe it was the monitor so I plugged it into my brothers pc, works completely fine and straight to 500hz, so I then plugged my old rx 6650xt in to see if it would work there, yet again it worked completely fine and went straight to 500hz. This leads to me believe maybe my gpu ports are broken or something, but I would also find this extremely weird seeing as both my other monitors did and still do work completely fine when connected to the gpu (1 1080p@144hz and 1 1080p@75hz) Honestly have no idea what is going on at this point.

Where are you setting the resolution? A PC doesn't just automatically go to the highest native resolution when a monitor is plugged in. You need to set the resolution in Windows for example under Settings, or via display adapter Properties > List all modes. If you have some sort of super scaling enabled, or custom resolution set in Adrenaline, that can also affect refresh rate and resolution. If you are using multiple monitors, are they all set to the same refresh rate and resolution? Are you using an HDMI cable, or a proper Display Port cable for the new monitor? Use DP, rather than HDMI if you are.

Have you tried using a different cable, HDMI or Display Port? Wouldn't fix a broken port but could be a work around. Otherwise return or RMA it.
