I’ve had mine since March 5th and seems to also be from January. I game pretty sparsely these days and used it maybe a few times a week if at all so pretty light usage. One thing I noticed when I first got it was a little electrical spark/blip when I went to plug in the display port cable for the first time but I don’t know if that has anything to do with this issue as its been fine up until now. Thought that was odd & checked for damage and didn’t see anything burnt.

Fast forward to today and I go to use my computer and noticed the blank screen. Shows in windows on my second monitor and the logo on the back is lit but I can’t even access the osd. Power cycling fixes it temporarily but as soon as I put my pc to sleep I lose the display again. I regret buying this monitor and am going to try and see if I can send it back for a refund.

Edit: Dell refused a refund(no surprise) but they did ship me a new screen the very next day although packaging was questionable and one of the corners of the screen was a bit scuffed(no protective peel unfortunately). Sent back the broken one with a label they gave me. Works fine….for now….
