[SOLVED] Monitor randomly switches to 1024 x 768

[Klanatic]

Alright so as the title says I've run into this problem. I recently got a new monitor (MSI Optix AG32C) and it's been pretty smooth sailing, but every few times once my computer goes into sleep mode after being inactive for awhile, there's a chance it switches to 1024 x 768 even though the monitor is set to 1920 x 1080. It's happened twice and both times I fixed with just pulling the plug and putting it back in (DisplayPort). I have no idea what's going on or if I should switch DVI or something, but I don't want this to turn out to anything bad.

What are system components' specs? What is the OS?

Bump, happened once again and still fixed it with pulling the plug and plugging it back in.

Asking to clarify from your post and make sure I get it right; when this happens have you checked the resolution settings in Windows? Does it show 1920 x 1080 despite the display actually being 1024 x 768?

If Windows shows the right resolution that the monitor is supposed to be running at in the settings and the picture is different it might be a graphics or monitor issue. It also might be a graphics driver bug.

As you said it's worth it to see if this happens with DVI/HDMI too or not.

Is the graphics driver the latest version? Also any driver for the monitor, is it updated? I would suggest you use DDU and remove the graphics driver completely and do a clean install of the latest version driver again.
