I recently purchased a new video card and two new monitors. Since then, I've noticed that often after the monitors turn off due to inactivity, when they wake back up one or both of the screens are very blurry. They look exactly the same as the pictures in this question: Monitor gets weird "blurry?" display

When this happens, the only thing that fixes the problem is rebooting the computer. Powering off or disconnecting one of the monitors when it's in this state not only doesn't fix the problem, but it freezes the computer (the other monitor stops displaying output and the computer won't respond to me pushing the power button).

Previous setup, when I had no problems:

  • Nvidia GTX 670
  • Old LCD monitor @ 1920x1080
  • Windows 10

Current setup:

  • Nvidia GTX 1070ti
  • Two BenQ GW2765HT @ 2560x1440
  • The same Windows 10 installation

Things I've tried:

  • Updating graphics driver, including uninstalling the old one first
  • Switching which ports the monitors were connected to on the GPU
  • Replacing the DisplayPort cables with new ones
  • Running and SFC scan
  • Making sure Stereoscopic 3D is disabled in Nvidia Control Panel

I'm not sure what else to try at this point. The post I linked to mentioned that the problem went away after upgrading from Windows 8.1 to 10, but I'm already on 10.

Current Nvidia driver version is 417.01

I think I fixed this issue by downgrading my Nvidia driver from the latest 417.21 to 411.63. Something appears to be broken in the new 417 driver build from Nvidia. My issue is described below:

I was having a very similar issue as you described. The problem happens after waking the computer up from a monitor off state, not sleep. My second monitor becomes very blurry after the monitors have been in rest mode for a few hours. I've tried completely uninstalling my Nvidia drivers and updating to the latest, no help. I've tried adjusting resolution when the problem occurs, no change. If I turn off the affected monitor; the computer completely locks up and has to be reset. This started less than a week ago.
