LCD screens dead pixels (page 10: Conclusion)

Conclusion

The main question: Why not a zero dead pixel warranty? All manufactures answered that monitor prices would steeply increase. This answer brings us to another question. How many screens are affected by this problem? Is it really one out of two screens? Even if it is very difficult to obtain official figures, one manufacture told us that 3% of screens had problems with dead pixels. This is a small number and if it is that amount, the manufacturers’ answer regarding the potential rise in prices really isn’t consistent…

Stores that offer money back guarantees

One possibility is to buy your flat screen from a shop that offers a money back guarantee. If a dead pixel is found, you will be able to take it back without even calling the manufacturer’s after sales service.

The last option: after sales services

It’s possible that dead pixels will appear after a warranty expires, and only one dead pixel located in the middle may be enough to ruin your flat screen. Your last possibility is to call the manufacturer’s after sales service. We advise you to remain calm and polite. Explain that it’s very unpleasant use your computer with such a bright pixel on the screen. Some manufacturers will respond that according to the ISO norm they don’t have to make an exchange but they will make concessions if the dead pixel is located in the middle of the screen. If the dead pixel is located near the edge this may be more difficult.

The future?

ISO said last year that they were working a new version of their norm. Of course we think that flats screens should have a zero dead pixel warranty, or at least this should be applied for bright dead pixels. Permanent black pixels are less disturbing and sometimes even invisible.
We also hope that this new version will bring new rules regarding response time and contrast ratio measurements…
