My monitor keeps going black??

So I recently bought a new monitor, Samsung Odyssey G5 1440p 165Hz, and it keeps going black every now and again for like a second or two. I am unsure what it is because when I was on 1080p 60Hz I wasn't having this issue. I have a 1440p build as I have r5 7600 + 7700XT and it isn't happening on demanding titles or anything, literally on chrome and stuff. Does anyone have a fix or any help? Thanks.
