So I have bought a new monitor (Asus VG248 quite a while ago) and I noticed something.
Whenever my monitor has been turned off, and I turn it back on, it sometimes gives me this display (hopefully clear enough):

Or

When this happens, my second monitor is fine.
The cause is random, it won't happen all the time it has been turned off and on.
I've searched a lot but no one seems to have the right answer.

I have tried turning it off and on again (ofcourse)
Removed power cable and re plugged.
Removed display cable and re plugged.
Tried to play with the settings.

The only way I resolved this, is by restarting my computer.

Situation

OS: Windows 8.1
CPU: Intel i5 4670k @ 3.4GHz
GPU: NVIDIA GeForce GTX 970
RAM: Dual Channel DDR3 @ 799MHz 16GB (2x 8GB)
Motherboard: Gigabyte Z97-HD3

Monitor 1 (problem giver): Asus VG248 144Hz 1920x1080 (PC: DisplayPort PS4: HDMI)
Monitor 2: LG 23MP55 60Hz 1920x1080 (HDMI)

Anyone that can help me out? Anything would be appreciated.


Solution 1:

Looking on this thread here - It seems there may be a link between this monitor and NVIDIA settings for Stereoscopic 3D:

For those still looking for a possible solution. I just put on the ASUS vg248qe for the first time and I had a exact sounding issue as the OP. Azza had the answer to my issue which was unchecking the "Stereoscopic 3D" setting in the Nvidia Control Panel. Quick steps:

  1. Open Nvidia Control Panel
  2. Click on the "Set up stereroscopic 3D" option under the "Select A Task..." section.
  3. Uncheck the "Enable stereoscopic 3D" checked-box.
  4. Hit "Apply" at the bottom of the Nvidia Control Panel window.

That is what immediately fixed my problem. If this doesn't help your case, I'm sorry and I wish you luck in fixing it.

Looking carefully at the images, the sides are cyan and red, much like stereoscopic glasses:
