Whats a lazy pixel?
I think some companies check for dead pixels before they ship them out. I had a Norcent LCD with a dead pixel, wasn't that annoying, you get used to it. I've had 2 BenQ LCD's and my friend has one, and theres no dead pixels at all. If you do end up taking back the Acer, try a BenQ one, I've been happy with them. My first BenQ LCD (17") had this weird issue where it would turn itself off, but I sent it back to BenQ, and they sent me a new 19" screen! Haven't had any problems since.
