strange image distortion after waking from sleep

[Memphis Raines]

I am at a loss, I have had this problem for a while, I have changed every connection i can think of but it keeps happening

if the system or just the monitor goes to sleep, randomly it will return distorted, I took a photo and a screenshot, but the screenshot was not distorted..

I have tried 2 DP cables, and HDMI, 2 different Gfx cards (1060 and 1070) and still it happens.. I have also reset my monitors settings.

I cant pin down the cause, my next test will be a seperate monitor, but the only one i have, only has a VGA port

What OS are you using? I've seen many systems have varying issues coming out of sleep. It tends to be a combination of the motherboard and OS/drivers. I'd make sure you have the latest bios and chipset drivers for you motherboard. It will be interesting to see what the monitor swap yields.

A few of us on the Destiny 2 channel have experienced this in the past few weeks or months. Pretty sure it's related to the 4xx Nvidia drivers. Not sure of the cause but it seemed to coincide with that and we're all using different monitors.

What refresh rate are you running at ? If it's 60hz, try running at 59hz and see how you get on and whether it happens then ( or dropping 1hz below whatever your rate is )

I have a suspicion that the Nvidia drivers are mistiming. My 4k was doing this a lot recently .changing the refresh rate by 1 has eliminated the issue.

thanks for the replies, so things to note so far..

• It seems to only do it after an extended time with the screen off, but system fans still on

• the current system is now Ryzen 1800x and MSI B450 with the latest bios.

• there are also seemingly well documented sleep problems with the Ryzen based systems,

• one thing that did just happen is the board failed to post after reboot when the screen distortion occurred.. had to manually power down and power on..

• checked the refresh rate, and it was running on the generic pnp monitor driver at 59hz instead of 60hz, so i installed the proper monitor driver
