Hi, I have a 3 screen setup, my main 30" monitor in the middle and 2x LG 23EA63 monitors each side. One of the LG monitors seems to developed some sort of screen burn/image retention. I can see a faint image of Skype and the taskbar that goes about a third of the way along from the left. I've swapped the monitors around to ensure it wasn't a cable issue but I get the same thing on the same monitor. It's weird because it disappeared yesterday for about 15 mins them came back, then it was a 'screen burn' of Winamp instead of Skype. Is there a way this can be fixed or does it need to be replaced?
