When I got my folks' last PC, there was one dead pixel. When trying to return it PC World said they had a threshold of I think 6 pixels (I can't remember exactly how many but it was a small number that still sounded ridiculous). They may have been bullshitting but it took a good half hour of arguing that the only thing I was concerned about was that they had sold me something brand new with an imperfection and I was not leaving without a refund or a replacement. They eventually replaced it.
