I just received my U2410 a few days ago, and it had a couple patches of stuck red pixels a couple inches apart from each other near the center of the screen. They were pretty faint, but about half the size of a dime and very obvious on a dark background. The disappeared when any amount of color was nearby. Color and backlight uniformity were excellent, and therefore there were no noticeable isolated areas of bleeding. It's no plasma, but its better than I had expected. This is my first LCD monitor, finally upgraded from my old 19" CRT.
This is my first Dell product. When you ask for support they'll ask you for the product's service tag. I don't think all of their monitors have one. I couldn't find a label anywhere on the monitor. Evidently I just didn't look very hard because when I called they informed me of a tab that slides out on the left side with the UPC. But the monitor is sitting at home and I'm at work. I had written down my purchase ID, order #, and the UPC from the box which was luckily the right one so they were able to gather what they needed. Why they couldn't get all the info they needed from the info they stored on my order I don't know. Anyways, I explained to them the issue and said I would like to exchange it for a new monitor. They said they were sending me a new one and that the box would contain a packing slip for sending the old one back. You put the old monitor in the box, slap the packing slip on, and hand it to the Fed-Ex man right there or drop it off at a Fed-Ex location.
They said they were sending me a new monitor. I am hopeful that it really is a new one and not a refurb as some people have received when exchanging. Maybe specifying that I wanted a new one and not just asking to exchange was all I needed to make it happen. Maybe not. We'll see in a few days when the replacement arrives. If its a refurb but looks just as good as the first minus the patches of stuck pixels I won't be complaining. I am otherwise extremely pleased with the monitor.
