Hmm, today is the last day I can return/replace my Dell monitor. I say replace because since I bought it back in November, occasionally the screen will blackout for one second. Some days it does it very often within minutes of each other, some days/nights I don't think it does it. I tried changing the cable, ruling out any other device connected to the GPU(receiver/TV) and any other cables.
I found a video of someone with the same issue claiming they fixed it by cleaning their system with DDU and drivers.
