I have AMD Radeon 7870 GPU, running Win 10 with a brand new HP 22CWA monitor. FYI the problem did not exist on the other monitor, but alas, it died.
So 2 problems really. My monitor goes to sleep and won't wake up without a reboot, even though the monitor clearly states that the connection is active.
Here's a shot from my AMD software.
You will see that the Virtual Super Resolution is turned on. However, it seems to keep turning itself off and then the screen goes pink.
To deal with the sleep issue. I just set my PC to NEVER go to sleep. So fingers crossed on that one.
But the pink? No clue. Please help.
