What is the best way to test for dead pixels on a LCD? A blank white MS Word document? If I'm going to spend $900 on a Samsung 191T it better have zero dead pixels. The computer store I'll be buying from has no restocking fee so I'll keep taking it back until a get a perfect monitor. I can probably get it cheaper when Dell puts their 1900 on sale but for peace of mind and having a computer store only 10 minutes away that I can go back and forth to all day if I have to, I'll pay the extra $100.
