Using a 4K Acer ET430K monitor and am getting green sparklies and flickering at 4K. Just reduced the resolution to 1080 and the sparklies have disappeared. I have also been getting an intermittent black screen that stays dark for a couple of seconds before returning to normal. This has been happening six to eight times a night over the last couple of days. Could it be both the monitor and the GPU or one of them?
Not sure if this needs to go in Graphic cards?

Could also be the DP/hdmi cable isn’t quite up to the job, that’s what I would try first.
If it’s not happening at 1080p then it’s unlikely to be the gpu so long as it’s being stressed the same when testing.
Could be a fault with the monitor, but again you’d expect the same at 1080. I’d try a new cable first and also stress test the card in the mean time to ensure no issues.

Agreed
It's going to take time. I installed the latest drivers and still had the same issue at 4k until dropping to two thousand by something. I uninstalled the drivers and then reinstalled them and it was fine for a number of hours last night. I won't know whether it is still OK until I get on later. What would you use to stress the gpu at 1080?
Update: I finally got rid of the green sparkles and constant flickering at full 4K by allowing windows to detect the monitor as a Generic P&P monitor. The screen still goes blank intermittently for a few seconds throughout the night, so maybe it's the monitor?
