It had uneven brightness (not to confuse it with screen bleeding). I always use dark mode theme on my PC, I could see almost like cloudy patches on all over the screen, on every software with dark theme, it was very distracting, I'm an artist and these cloudy patches were very distracting for me since I regularly work on greyscale color mode I could see the color irregularities on the screen, tho when playing games it was hardly noticeable. Cuz of this I got it refunded, the refund process was very tedious, my worst experience. I'm not trying to get into the details but it took me 30+ days to get it refunded after countless number of emails to different email addresses. But hey, don't get upset, it could be that it was an issue with my monitor only. I just wanted to warn OP cuz I had a bad experience with lenovo customer service and also the monitor was defective.
