One of my HP ZR24w's has developed a fault. On the edge which sit's next to the other monitor a stain like mark has appeared running the height of the monitor. This has developed completely on its own accord, and first appeared just over a week ago. At first I thought it was something on the screen, but on closer inspection I could quite clearly make out remnants of text as if it had been burn't into the screen. The problem area coincides with where my layers properties window sits while I work in AutoCAD and I could quite clearly make out the names of the layers which matched the document I have recently been working on. There were also remnants of my photoshop layers window as well, although much more feint. Looking online I came across a possible solution which involved running a screensaver switching between solid white and black screens every 6 seconds. I have allowed this to run over night on a couple of occasions which has significantly reduced the presence of the text, but the large stain like mark remains. Here's a couple of pics of what remains: Any advice on a possible way to fix the issue? I purchased these monitors on the 17/09/2010, so as long as HP have a 3 year warranty I could still get it replaced hopefully. There is something on their site about not covering image burn-in though! But this looks like more than image burn-in, because nothing would create the stain like mark. Almost looks like a couple of the layers which make up the screen are coming apart? Finally, if I can get it replaced, does anyone know if these screens are being produced any more, and if they are has there been a revision change? I'm a little worried that if I can get it replaced it will no longer match the other monitor I have in terms of image. Edit. Just checked on the HP website, and I have HP HW Maintenance Onsite Support until 9th of October. Anyone dealt with this onsite support, what's it like?
