I just received my refurbished thunderbolt display, and I'm ecstatic, however there appears to be several problems. The first one is one that appears to be common: there's a 1 inch line of slightly dimmer pixels just above the dock that spans the whole display. It's only really visible in fullscreen mode with a white background, so it's minor, but still an issue. The bigger problem, though, is the backlight. I've attached images (50% brightness in dark room, max brightness in dark room, max brightness in a lit room) to show this off. I just want to know if this is standard for these displays, or if I should contact Apple and have a replacement sent out.
