I recently sent the ebay-seller Greensum a question asking him the exact difference between his advertised listings below since both ads depict a tolerance description of dead pixels rather you purchase the " Perfect Pixel " or the cheaper one. Below is the reply i received from Greensum as others in the past may have also wanted to know.

[ Hello, this is Green-Sum, the eBay seller.
First of all, we would like to say thank you for your interest. We will always make our best efforts to support you.
The cheaper one is not perfect pixel optioned. With Perfect pixel option, 0 dead pixel allowed. Normal one, up to 5 is acceptable.
Dark dot and stuck pixel are not considered as dead pixel. Bright dot only.
Dark dot : The pixel shows dark and cannot be found on Black background. If the dot show other colors, bright dot.
Hope the answer above helps you. We are looking forward to have a good business chance with you.
I quess i decipher his response being if you purchase the " Perfect Pixel " the dead pixel tolerance factors would be the same as if the consumer buys a name brand monitor from any of the familiar online vendors here in the U.S.
I do appreciate the fact he does reply back and his english typing skills are very adequate.
Anyways just thought i would relay the reply so folks on the fence would know the difference between the two units he sells.
