If an LCD is originally dead pixel free and stays that way for the first few days or weeks of its life, what are the chances of a pixel ever dying in the future? Slim to none or is it a valid possibility?
Likelihood of pixel death after first few days?

slim to none, it depends on how much quality there made with. but just a pixel dying the first week doesn't meen all of them will soon.
I've had my LCD for months and it still only has the one dead pixel it had to begin with...I was under the impression that a dead pixel was bad from the start (manufacturing error maybe), not something that was likely to happen with use of the monitor.

Those are a waste of money to begin with IMO.
My old NEC 17in LCD developed 1 dead pixel in the first week I had it. I used it for about 2 years, and no other dead pixels showed up. The Dell 2005FPW 20in panel that I have now has only been sitting on my desk for the last 5 days, thus far, no dead pixels that I can see.
Larger/higher resolution panels tend to have a higher rate of dead pixels because of the pixel density.
Well, the BB PSP on LCDs is actually pretty decent, because they'll service or replace the monitor if it has only one dead pixel. That's why I ask this question, I wonder if I even have to worry about that too much after the first two weeks.
Just be sure to stress out your monitor for a couple days when you first get it. Set it to max brightness, max contrast, etc., then having it run white/black screens continually. Hehe.
Most (but not all) pixel defects are already there when you get it, but simply don't get stressed to failure until later on. So it's important to make it really work to test out the screen. Then, like a car engine, you shouldn't stress it out too much after that for extended life, so put the settings at the minimum tolerable after that =P
Otherwise, you can always try rubbing them and seeing if that works.

Thanks guys. I will just make sure to stress the monitor during those first two weeks of its return period at Best Buy, so if something goes wrong I can return it. Hopefully it'll stay fine. I won't buy the PSP.
actually dont do that to your car. it is supposed to be driven anywhere from 3000(camry) to 5000(RX8) miles very gently(not above 4000rpm(camry), 5000rpm(RX8) according to ll manuals.
Oh I didn't mean you should drive your car very harshly for the first few weeks. You don't need to anyway, since most cars I know of have a warranty that lasts longer than that. It's different with monitors though because some warranties (i.e. zero dead pixel guarantees, or if nothing else, a brick and mortar's replacement and/or money-back satisfaction guarantee) only lasts a few weeks. So I was just saying that if you're under one of those warranties, to stress out the monitor in the beginning, to really test it out to its limits, then never approach those limits again (for maximum life of monitor and minimum chance of new dead pixels appearing) once the warranty expires. Then again, it's also possible that stressing the system primes dead pixels for failure over time. That's always the case with any sort of destructive testing, which is essentially what you're doing here (except not testing to actual destruction). But given that most dead pixels appear fairly early, with few later on, I'd rather take my chances and stress out my monitor in the beginning if I have such a warranty. Naturally, if you don't, you might as well as play nice rather than introducing dead pixels by making the monitor go to settings that you never use.
I remember testing out one of our display monitors, by doing something which made the monitor blink and other weird stuff. Shortly thereafter, I noticed that it had developed a green bright subpixel -- after quite a few months of sitting there in the lobby running screensavers continually. So it may possible for new ones to develop afterwards; however, it's also possible that the screensaver never really tested the monitor to its limits (duh...it's just the stock aquarium screensaver), and that it had been primed for a dead pixel since it was made, but simply never reached the "breaking point" until I made it do weird stuff. I don't know. Until then, though, the monitor never had any dead pixels. The sales guys weren't too happy with me. Oh well. I had an AOC 15" which had 2 dead pixels first time I turned it on, but they never bothered me. No new ones appeared for the next 3 years I had it though. I now use an Amptron G19FP, which has never had any dead pixels develop. So with my small sample size of 2 monitors, I haven't had any dead pixels develop over time. And no I'm not going to tell you what I was doing making the monitor go crazy, in case it's inadvertently a way to generate new dead pixels =P
So what to stress it out with, you ask? Well, I don't really know the answer to this question. I'm guessing that you'd probably want to alternate white/black (no point using color because you might as well as test out all three colors at once i.e. white), after leaving it in one and then the other for a while (leaving it in black for a while and not just white is important I think). I don't know if you got a program that does random white/black though (i.e. DisplayMate I think). If you're bored though and got no idea for a screensaver that'll alternate white/black, you can always try out Wizmo from grc.com ( http://www.grc.com/wizmo/wizmo.htm ) since they got a nice Graviton screen saver. I used to sink hours into it playing around with the settings, then watching all the particles gradually coalesce from being evenly distributed across the screen to a spherical ball of little balls all under each other's gravity (I didn't watch it continually, just the first few minutes, then check up on it every so often). I have no life.

Thanks for the tips.
This monitor will be moved around a lot, being transferred between school and home. If I ever lightly bumped it, could that cause a dead pixel? Is that a good reason to maybe get the service plan, the fact that it will be moved around a lot?

I guy I knew dropped his monitor on the floor and got a new one. That's the easy way of getting a new one quickly, but if you were to do it consciously, I guess that would constitute fraud.
Well the BB PSP does not cover abuse, but of course if you bumped it and caused a pixel to die, they probably wouldn't know it was abuse, and you'd get a new monitor.
I was positive I wouldn't get it until I thought of this. Hmm...
