How many dead pixels do LCDs have?

[Misiowiec]

Simple question really, but what is the risk (if I can call it that) for a new LCD to have dead pixels? At the moment I have an Iiyama 17" LCD which has no dead pixels, and I'm toying with the idea of getting a 20" widescreen Viewsonic VX2025. The biggest turnoff would be if the new screen had dead pixels, and if this would be below the treshhold at which the manufacturer swaps it. In Viewsonic case the policy is:

"If the monitor has a full dead pixel (black or white) then the unit will be swapped out. If the monitor has sub pixel failures (Red. Green or Blue) then you are allowed a max of 10 before the unit can be swapped out, this in compliance to the ISO 13046-2 Part 2, pretty much all the manufacturers adhere to this standard".

So, what's the risk that I'll be staring at a dead pixel and is it worth the risk?

Bit of a gamble really. Who knows until you open the box?

That's what it seems like! Would I buy a car if it had a dent in it's bodywork, however small? Most likely not.

I don't know how bad a dead pixel really is to have (never had one), but I can imagine it would be very and a real dent in the bodywork.

Great replies, thanks guys. In particular the Distance Selling Regulations with the 7 day cool-off period and the Sale of Goods Act might come in useful.

As many others I don't feel I should have to accept anything less then zero dead pixels.

Now let's go shopping
