Wondering if anyone has seen a pixel behave this way. It is not just an always dead or bright pixel, it is a stuck pixel (red) near the bottom left and it only shows up after the monitor has been on for 15-30 minutes or so. It then goes away when the monitor is off for a period of time. I have tried putting pressure on it and using various pixel fixing apps to no avail.

Is it worth returning to Amazon over one pixel when I might just get a refurb with 2 bad pixels or even a new with another bad one or does anyone know of an alternative way to troubleshoot this thing? Thanks.
