If you got stuck pixel (light pixel), then maybe it is possible to fix it, just simply by running the video below (transfer it to your device).

Run it several times a day, sadly N900 does not support "repeat" in the video player, else it would be nice to run this video all night, so you don't have to manually start it over and over again.

NOTE: No guarantee it will work, on only possible to "relive" stuck pixels, that are light or white (you can see them on the black test above).

A 50% fail rate sucks!

I don't see any dead or stuck pixels on my screen, but at this resolution it would be possible to miss some types even with good eyesight.

However, I have had it get into a state where the top-left desktop icon is a little bit corrupted. I worried that my screen had developed dead pixels, or that RAM/Flash was failing already, but a reboot fixed that. It only happened once, but when it had happened, entering various apps and so on and returning to the desktop did not fix it - only a reboot did.

i have one stuck on Red. I've tried several videos and websites with patterns to resolve. No luck. It's really annoying when watching movies is all. Otherwise it doesn't bother me too much

My first one had 5-6 stuck pixels so I've asked for a replacement. Second one had more than 15 (!) so I've returned it for a refund. Poor quality screen but at least the Nokia Online Store accepts it back and they don't try to explain to me that this in not really a fault and that it is within tolerance... that kind of explanation just raises my bloodpressure. Referring to an old ISO standard and pulling it all out once the customer had already paid is just nauseating.

The stuck pixel or subpixel is sometimes visible from a certain angle only so tilt the device around gently. I bet that a lot of people simply cannot see the stuck pixels even if they are there.

I would be willing to pay extra if I received a guaranteed pixel perfect device. Some monitor manufacturers do this already.

Thought I didn't have any, then I used my phone before sleeping, and in the bottom corner I have one. Going to try this video thing :S

Mine's absolutely flawless. I expected several defects on a screen with such a massive number of pixels at such high density, but I'll take perfect instead!

I don't have dead pixels but instead a dark spot in the backlight diffuser. It's about one millimeter in length. The pixels appear to hover over the spot and there's a strange parallax effect when I look the N900 from different angles.
