Question DisplayPorts on Nvidia 3090 are no longer working after moving house ?

I am a dumbass who didn't remove my MSI GEforce RTX 3090 graphics card from my computer when I moved and now after trying it out the DP ports all produce extremely blurry output. I thought it was broken completely until I tried the HDMI port and it works just fine. Most of the time I can see the loading and bios screens clearly (i don't think that can be the CPU display since I have an F series), it's only when Windows boots up that things get blurry.

Once or twice I was even able to see the Windows output clearly for moments before it corrupted and went blurry again. To complicate matters, I was already having far more minor blurry output issues on one of the monitors before my move. It would come from the bottom of the screen any time I first booted up or came back from being idle, but went away fairly quickly.

I read it's a common issue with my VIOTEK GN32Q monitors. So for all I know this is more about them than it is about my graphics card. But it still doesn't really make sense for the issue to escalate to this extent and on both monitors at once, which makes me think it's something with the graphics card. Maybe I bent something in it when I moved it, but then why would only the display drivers stop working? Is it possible the card isn't receiving enough power now like perhaps a cable got loose? But then same question why would the HDMI port still work?

I can't figure out how to attach a picture here but I linked to what the output looks like on imgur below.

Things I have already tried that didn't help:

Reseating the card on the mobo (ASUS TUF Gaming Z590)
Tested different display ports with different cables
Updated my graphics card drivers
Lowered the refresh rate on my monitors which it seems can't be done, the only options are 59 which they are on, or 60

I do like to game and the card only has one HDMI port for my multiple monitors so I would definitely like to fix this issue if I can. What further steps would you suggest I take?

Thanks a lot!
 
Your monitor seems to have a DVI port. Does that one work? Use DVI/HDMI adapter for it.

Try a different monitor.
Try a new displayport cable.
Yeah the fist thing to do is to get a screen with a DisplayPort that’s known to work and a cable that’s proven to work en go from there.

There could just as easily be something wrong with your screens as with your gpu.
 
Thanks guys! I will order a DVI cable with an HDMI adapter for testing and a new display port cable but I don't really have access to any other monitors to test. Should I buy one with the intention of returning it perhaps?
 
I turned off auto-sleep and left the monitor on for several hours and eventually all of the weird lines slowly faded away O_O Guess I'll just leave it on forever now.
