The first one I received had 9-10 dead pixels. I initiated a replacement unit. The replacement unit arrived in around a week. It had a slight lighting issue (an area was a bit darker than rest) at the bottom center, but it was hardly perceivable and is easily not a big problem. Also there were two or three half dead pixels (like only the green not lighting up), which is not an issue too as I was unable to perceive them from a feet away. The best part is that both the monitors had no flickering issue which customers got when the monitor was initially released. If you have the money, go for it. My productivity increased a lot, no matter what I did with it (I do mostly programming). And IMO, 1440p spread across 32 inches is way better than 1440p on 27 inches. I personally found UI elements too small on 27 inch 1440p monitors, and increasing font sizes and UI scaling, the experience just doesn't cut it. It's not the same as vanilla unscaled resolutions.
