My rig:

  • AMD R9 Fury
  • Desktop
  • Windows 10 64bit
  • Radeon Software Crimson Edition 16.8.2
  • Asus MG279Q 2560x1440@144Hz DP->miniDP cable
  • Asus X99 Deluxe
  • Intel Core i7 5820k
  • Corsair AX860
  • 16GB RAM

 

I have been using the monitor for a month with Nvidia GT210 video card, 1440p@60Hz via hdmi. I haven't experienced any issues. I have received my R9 Fury to take advantage of freesync technology. At first glance everything was fine: monitor works 2560x1440@144Hz. But I have found an issue soon. A weird vertical line in the middle splits the screen with a small mirror effect. I think it mainly occurs when switching in-and-out of games, but also during regular browsing/office work in 10-14 minutes. It doesn't depend on freesync on/off, I have tested several drivers, but it doesn't help.

I am not the one with the issue, I googled a couple of same stories:

Since I haven't any issues with GT210, I guess there might be a driver/card issue.

Could you please help with investigation?
