I received one of Dells desktop computers, I was surprised to see on the flat monitor a sticker indicating that there are 2 dead pixels. After ignoring e-mails I rang Dell to check this out. The reply was that the industry startard for the size of screen is 6/7 dead pixels, and the sticker is the result of the quality control at dell. Dell said that any screen that has no more than the industry standard for dead pixels is an acceptable standard for shipping to customers.
I don't think I would accept any dead pixels on delivery. I am sure others on this Forum would agree. OK, so the accepted limit is about 5. But would you accept a 160gb hard drive that has a sticker on it saying that there are 50gb bad sectors?
All tft's will have some dead pixels-?? I have an IIyama Prolite E481S 19" TFT it has no dead pixels at all, I would not except a monitor with any dead pixels at all I would return the monitor as faulty a.s.a.p
Some manufacturers have a zero tolerance to dead pixels, others will state the industry standard's rule. In general though, it is excepted that a dead pixel in the centre of the screen is a replacement or refund issue.
A method that as been tried, and appears to work [by other accounts], is to get a cotton bud, slightly damp it, then run in a slight circular motion over the area of the dead pixel, do this in a very gentle way. The dead pixel may or may not disappear, depending on your perseverance.
a handy utility for finding dead pixels you never knew existed click here personally, if i haven't seen em, i don't want making aware of them. good to have for when you've just bought a new tft though.
