It's tough to draw comparisons with this poll since a 3-chip projector (LCD/LCOS) has three times as many elements as a single chip projector (DLP), and high res projectors have more pixels than low res. An SVGA DLP has 480,000 pixels, XGA DLP has 786,432 and D-ILA has 4,193,280 subpixels!
The more pixels a projector has the more likely it would have one or two stuck ones, but the less likely you would notice them. With a three-chip projector a stuck subpixel only shifts the colour of the pixel rather than knocking it out completely like on a single chip DLP, and on a SXGA+ projector the pixels are so tiny that they're nearly invisible.
It's also important to know if the pixel is stuck "always-on" or "always-off". The always-off ones are generally less noticable than always-on.
I agree to a large extent, but the bottom line is that many people can and will spot a single pixel error. Powerstrip was causing 1 pixel on my display (Sharp 9000) to stay white form time to time and it drove me up the wall.
At work, we have an XGA Proxima LCD projector and I can spot 3 problem pixels without event trying to.
I still feel the poll is valid and am anxious to see how the number stack up.
