I have a friend that bought a monitor with this problem! It took us FOREVER to figure out why it just didn't look right in 1440p. I couldn't tell exactly whats off exactly it's not technically "blurry" but we went through hell and back trying to test everything to see why it looked off. Finally we broke out the macro lens to look at the individual pixels of the monitor in question and compare it to another 1440p monitor. That's when we triple checked and couldn't understand what we were looking at. The pixels were SMALLER on the wonky panel. We thought that maybe we got the wrong monitor or maybe there was a packaging mistake at the manufacturers. Returned the monitor for full price after arguing with costumer service for a month, but finally he got a full refund. Not going to say the manufacturer and brand because reasons.
