I recently bought the Benq XL2540, which is a 240hz monitor. My GPU is a R9 290. Everytime I start my PC the monitor runs at 144hz, but after turning it off and on again it is running at 240hz. If I then switch to 144hz and later back to 240hz the screen stays black for quite some time, then the driver shows a Link Failure. Should mean that it won't work, but 240hz is selected and it is actually 240hz and works. Is this simply a driver problem and needs to be fixed?
Thanks for your help .
