I recently got a AOC CQ32G1 which at first appeared to be working perfectly but I started to notice the colours turn white and then back to normal and artefacts. To see if it was the gpu causing the problem i used obs to record the screen while I went through benchmarks and some games and I never noticed problems when I closed obs artefacts started showing up and the screen turned black for a short time. Is the problem with the gpu or the monitor? I’ve also changed the cable and that didn’t make a difference

Gpu: https://www.amazon.co.uk/gp/product/B01GJEE9BG/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
Both the display and gpu were bought as new

Is that a movie playback? Or cut-scene in some game?
If movie playback - do you have same results with different video players? Vlc? Media Player Classic?

Anyway - reinstall gpu drivers with clean install option.

Install codec pack for movies - Shark Advanced Codec Pack

It’s a scene from a game
I’ve fully reinstalled drivers with a clean install and the artefacts are still appearing
 
Do you use same video output (on graphics card) for old and new monitor?
What cable are you using? Any adapters?
What's the model name of old monitor?

So new one is 2560x1440 144Hz.
Do you experience same artifacts with different resolutions, different refresh rates?

The new one uses a DisplayPort cable and the old on uses hdmi no adaptors

I would say it could definitely be the display port, mainly because it doesnt happen with hdmi. And if your new monitor has no hdmi it can be hard to tell if its the monitor or the dvi port on the gpu either way your gonna have to replace one to narrow it down to see what it could be exactly. good thing its still new as you should be able to do an rma and figure it out fairly easy. Patience is the hard part.
