I bought a 1901FP around Sepetember, 2004, and have been very pleased with it.  However, around December, I noticed that a large cluster of dead pixels had appeared in a 2x2 inch region at the bottom right corner of the screen (about 20 of them, sort of spread apart).  The odd thing is that instead of being white or even just brighter than the rest of the screen like most dead pixels are, these ones are dark.  I'm very sure that they're not just dust because I've cleaned off the monitor before and these are the only spots that remain, plus I can tell they're part of the screen itself when I look closely.  I don't know if these were here when I bought the monitor because they are fairly easy to miss when the background is colored (like it usually is), but they're obvious when the background is white, and now that I know they're there, it nags me when I'm using Word or anything else with a white background.

Does this fall under my warranty?  And if so, how much longer do I have to return the monitor for repair before the warranty expires?  I read that monitors come with a 3 year warranty, and I bought it separately so it doesn't fall under my computer's warranty.
