A, B, C : Acer, Apple, BenQ...
Apple : So far Apple only dealt individually with dead pixel issues. Even if reader’s feedback weren’t that bad, we found quite strange that Apple’s client didn’t beneficiate from a minimum policy.
That just changed today. The new official statement is: Apple displays meet the ISO 13406-2 specification. Any customer who is concerned about pixel anomalies with an Apple display should contact an Apple Authorised Service Provider (it also include people who doesn’t meet the ISO 13406-2 requirements).
BenQ was one of the only few manufacturers not to answer our questions for the first article release on dead pixels policies. Today, by looking at their answer we understand why. They are the only one not to use the class 2 of the ISO norm, but the class 3 for entry level products: the T series. With this series the number of dead pixels tolerated explodes!
We find the norm 2 already inappropriate, but the use of the class 3 is really shocking. This choice is in complete contradiction with the policy of a manufacturer who is trying to push their products’ quality image. This attitude is really a shame for a LCD manufacturer especially if he sales products to the general public. We hope that BenQ will change their dead pixel policy soon!
