I have owned two of these monitors for a couple of years and one has already started to fail. It has started to turn green around the edges. I would expect this out of a cheaper/lesser screen but not one that is marketed towards the higher end. The best part is when you call in about a warranty claim the don't want to honor it because you didn't purchase it directly from them.

I do have to say this monitor is great when it works. However I would not recommend it if you are expecting it to last a long time.
