So, I noticed some dust on my monitor (NEC FP950) today and decided to give it a once over with a tissue, but there were a few spots of buildup that wouldn't wipe off. So I put a little elbow grease ...

I recently got a good deal on a HP zr24w LCD monitor from MacMall. I think it has a single dead pixel (dark) in the upper left corner. Would you try to return or exchange the monitor for this reason?
