Windows without any drivers works fine with displayport. Bios shows up too. But after installing the amd gpu drivers it goes to black screen and says "Displayport: no signal". After that, when ever i boot to windows it says no signal but i know that my dp cable works fine. Also hdmi has no issues, so at the moment i am using hdmi. I tested displayport on my gpu via hdmi to displayport converter and it works so gpu is not faulty. Again, my monitor wouldnt display anything if its displayport was broken. I was lucky enough to get a second monitor to see whats happening while i plugged in the displayport. When i plug in the displayport, pc starts stuttering, gpu drivers starts doing janky things like monitor keep dissappearing and appearing. After a while drivers completly crashed. I tried installing older drivers like 19.12.2 but still same.
My pc specs are:
-Ryzen 7 2700x
-Asus tuf x470 gaming plus
-rx590 saphire nitro+ 50th year edition
-Gskill ripjaws 3200mhz 16cl 2x8gb
-Toshiba Ocz RC500 250GB
-Coolermaster 750W 80+Bronze
-Monitor: ASUS 27" VG27VQ TUF GAMING
Im really frusturated because it makes no sense to me. I believe its a driver problem.
