To me, this policy seems woefully out of touch with the times. Dead pixels are completely unacceptable to me on anything I use all the time, such as my computer screen(s) and TV (I'm just talking in general here). Having a single dead pixel would drive me insane. The product is malfunctioning and needs to be fixed or replaced, plain and simple. I will not accept anything less. The number of dead pixels allowed should not be a function of the overall size of the display (and resulting number of pixels).
It's like if I had a problem with my car or any other piece of equipment I own. If it is not functioning as it should it must be made so that it is.
It'd be like the mechanic telling me that one of my cylinders in my car isn't producing compression, but not to worry because I have five more that work fine. Ridiculous.
I regret to inform you that you already are.
