I bought a RX 5700 XT and installed it. Looked like it was working fine, but somehow my screen looks like an ecoline painting. The colors are there, but are really weird as you can see in the uploaded photo of my screen. I tried to remove the drivers manually and with 3rd party software, but no success. I tried changing the color settings in Radeon settings, but again no success. After that I tried different cables, different screens earlier driver versions, checked al cables twice but I can't find what is wrong. The only thing I noticed was that amdkmdap, which is my display driver apparently, doesn't start.
Anyone knows how to fix this? And has/had the same issue?
