I bought a brand new PC with an AMD Sapphire R9 390 graphics Card and a iiyama ProLite B2783QSU-B1, 27" Monitor which especially says Freesync support as a feature.
I am using a fresh installation of Windows 10 Pro 64bit. I connected the DP cable which came with the monitor and I use the latest Crimson Drivers from the website (also tried older ones).
In Windows i get crazy flickering, white stripes and popping sounds. This happens more frequently when i use my inputs like mouse or keyboard.
When I Switch to DVI it works fine but I can't use Freesync since it is only supported with DisplayPort.
I searched here on the Forums and on Google and found a crazy amount of other people having the same issue but nowhere to a good solution.
I don't want to order an expensive new cable or send back my monitor/graphics card since most sources say it seems to be a driver related problem.
So does anyone have a solution for this or does even AMD acknowledge this problem? Is there a solution planned with future updates?
Any help would be appreciated, thank you in advance.
