Since my monitor (Shimian 27" inch IPS monitor) does not have a DP port, I had to purchase a rather expensive adapter to connect it with the Vega 56.
It actually works okay when I don't have any Radoen drivers installed. However, when I install latest Radeon drivers (also tried blockchain drivers), static artifact takes over the entire screen (I can still somewhat see the what's underneath). Like this:https://ibb.co/eGYMLz
Only resolution is to uninstall the drivers, but then I can't play any games and have also stability issues.
I tried to setting the refresh rate on Radeon settings, with no avail. My guess is that the adapter isn't able to "handle" the latest features on Radeon drivers?
