Hello, I bought this new from greensum (eBay) about 1 month ago. I used it for 1 week, I since then purchased a PB278Q because I wanted the extra inputs and a OSD Menu.
This Monitor has never been OC'ed
There is no Dead Pixels, I even checked it with a magnifying glass.
There is no light bleed noticeable when on the Windows Desktop, When on a black background in a dark room I do notice a slight possible bleed at the top middle its about 2 inches across and drops down...
