Dude, most poeple won't take it back if it has less then 15 dead pixles, so be VERY glad you got one with such few errors.
My mom's office uses the 19" version of those and they are VERY nice. Don't go with another choice just because of a few dead pixles, you won't excape that.
If you are still worried about it, ship it to me, and I'll ah....see what I can do...
