How is the GPU connected to the monitor?
What AMD drivers are you using?
Monitor is connected with DVI- cable (should be new and working, came with the monitor that is BenQ XL2411Z btw). Graphics card has to connections for DVI, tried both of em. I have tried setting it to 144Hz, but it only seems to give me an opportunity to use it as 120Hz and then it forces resolutions very snall (like 800x600).
Drivers should be updated here is a screenshot of current version:
I would really appreciate it if i would find the solution for this
