Stuck or dead pixels at monitor boot (Asus ROG PG279Q)

[VikingGaming]

Hello everyone! The last couple of times I've started my Asus PG279Q monitor, it appears as if a whole bunch of pixels are temporarily stuck or dead. They appear white/grey and it spans across the whole display. It gets better the longer the monitor stays on, and they eventually go all back to normal. I was wondering if it might be something related to temperature? The room the monitor is in can get quite cold (about 15-20C (59-68F)). I tried my best to get pictures showing the problem, but I find it a little challenging to get good, clear pictures of monitors with my phone (I tried my best). The middle picture shows it the best.

I honestly cannot see it.

Do you mean dark spots?

It's difficult to get across on pictures, I know. As mentioned in the post, they're white/gray. In the middle picture it sort of looks like specs of dust.

It maybe a gpu problem. Overheated gpu can cause display error.

Unrelated, as I always turn off the computer when I'm done with it. This started happening all of a sudden, and at boot my GPUs are at 35c. And the longer the screen is on, the more the specs fade away, until completely gone.
