Has anyone built one of these using an LCD that has a lit pixel (one that in this case is red all the time)? My brand new benq from ncix has one in the center of the screen, and while I did opt for the "zero dead pixel" warranty, I wouldn't be surprised if they distinguish between "dead" and "lit" the same way that the industry does, 0 dead are acceptable, but up to 3 lit/screen is ok (I'm still waiting on a reply to my inquiry regarding a replacement). I'm just curious what kind of flaw this will create if used in a projection setup - will it be blured away to nearly un-noticable, or will it be a 1"square red dot in my projection?

I think what you have there is a pixel on life support. For all intensive purposes this pixel is dead, it’s a vegetable.
A possible fix if they won’t exchange it would be to give it a massage if that doesn’t work black it out with a permanent marker.

The pixel is dead by all meanings of the word, because the LCD cell is stuck-off (not recieving power), allowing light to pass through it.

And if you WERE SOL and had to use a marker, don't use a permenant one smile.gif Stick with wet-erase.

Guys, he didnt ask if it were dead or on life support. He asked how much of an effect it would have on a projection picture. biggrin.gif

Did you try the pixel massage yet?

If you have any doubt as to whether they'll honor the warranty, kill some more pixels and RMA it. While it may be slightly dishonest (it was a defective monitor anyway), it may be the only way to get them to keep their word.

I've never heard of the pixel massage, but you may want to give that a shot first. It sounds less destructive.

if its stuck on I would definilty try to massage it or cover it up, I fend stuck on pixels very annoying at normal size when its much bigger it would drive me crazy, I would get one of the ultrafine sharpie cd writing markers and use a magnifing glass and try to cover up the pixel if the massage doesnt work

How would you go about destroying a pixel?

Pixel massage is a way of fixing stuck pixels. If done with too much force then it can destroy them. There's a few "pixel massage" threads in the subscribed forums here.

Chemlab, you can try a search for "pixel massage" and read up on two or three experiences to learn how to do it correctly. It has a decent chance of reviving stuck pixels.
