A few weeks back I bought a Dell 2408 monitor, yesterday I found a annoying little pixel that when it should be displaying black it displays green or red. Im only seeing this issue when black is being displayed.
Its not heaps obvious, it did take me a couple of weeks to notice it aye, but is pretty annoying now that I know its there.

Has anyone heard of pixels behaving like this? I've heard of stuck and dead pixels but this is something different I believe.
Any thoughts on this or suggestions on how to fix it?

Green or Red? That sounds weird, I've heard of and experienced subpixels being stuck on before but usually only one colour at a time.

Try some gentle rubbing, if it doesn't work you might have to check Dell's return policy.

Tis a dead pixel. Tis normal. And you are stuck with it. And if it is not right in an obtrusive area of the screen most manufacturers consider it within specification.

Although some do have a zero dead pixel policy. Might be worth checking that out. I've had red ones, blue ones (least intrusive I find) and a black one where all three subpixels (RGB) are dead. On various screen over the years.

Wikipedia (I think) has a great page on how complex lcds are.... three "Sub pixels" for every pixel on the screen: 1440*900*3 for me: 3,888,000 (yeah I did that in my head) little lights to turn on and off at the right time to get your image.

If just one of those connections is iffy, you get a dead pixel. Bigger screen, the more massive the number and the more likely a defect.

Obviously manufactures can buy slightly faulty, but "Passable" screens for less money than perfect screens, so for the cheap displays we get these days dead pixels are becoming a part of life for some. My last two macs have been without them. My last powerbook had a red one.

dell have excellent warranty, call them tell them you have an issue & they will send you a replacement, with postage set up for the return of the faulty item.
