Noooooooo!!!!!!!!! Is this bad, does this mean my 200$ monitor is dying on me??????

One just died today, turned black.. Does this just happen sometimes? Will my monitor be ok...

Damn, I am not heppy... The trinitron downstairs has lasted longer than mine..Of course, I bought it off ebay, so I don't know the history of it, but the person that sold it said it was never used.

ouch, thats just something you're going to have to learn to live with.

i was at the good guys the other day, and there was a $10,000 Sony 42" Plasma Widescreen TV.

Right in the middle were 2 dead pixels. from 3 feet away they were really distracting.

You normally don't sit that close to a big screen, I sit ~ 6 feet away from my 32" widescreen TV

Pixels from LCD displays can die, it just happens.
A dead pixel right in the middle of a LCD display can be annoying, more to the edge won't distract that much.
OK, a dead pixel might be bad, but it could've been worse than a black one ... it's more likely to get a pixel that stays green or blue or red, those are really annoying.

hell, the Toshitta laptop I had at work had two dead pixels, I got used ot it after a while. When I say dead, in this case one had the green element stuck on and the other had the red element stuck on.

I'm not on a LCD, I am on a 19" Trinitron..

I also have 2 horizontal lines (one at 1/4 the way down, the other at 3/4 the way down..) lines (what are those from?).

A dead pixel on a CRT....
I think that would need a bit more explaination, you are talking about different technologies

the two horizontal lines are supose to be there, just get use to them

The aperture-grille (Trinitron/Diamondtron) CRT uses a grid of extremely fine wires to separate the pixel triads, and those two horizontal lines you see are heavier-gauge damper wires. Basically they keep the grille stable.

That sux... no cure for that other than a new monitor.

And for u other guys: You can get "dead" pixels on CRT's too not just LCD's

It's just very rare that you get "dead pixel" mentioned with a CRT

There are two phenomenon which define a defective LCD pixel: A "lit" pixel, which appears as one or several randomly-placed red, blue and/or green pixel elements on an all-black background; or a "missing" or "dead" pixel, which appears as a black dot on all-white backgrounds. (By comparison, CRT defective pixels exhibit themselves as black holes in an all white raster. This is due missing phosphor material or an obstruction in the shadow mask.)

The transistors in an LCD are switching all the time and can just die after some time, leaving the pixel stuck, so that's something more likely to happen than a CRT developing a dead pixel after some usage. That is why most people think "LCD" when they hear "dead pixel"

I've got 4 dead pixels on my Viewsonic LCD, but I've learned to live with em. Since I use this monitor solely for programming and word processing, its not really a problem.

Ok, well, it's black, so it isn't a HUGE big deal... Just kind of scary.. Guess I just got a monitor that just happen to lose one of its pixels.. Not very noticable unless you look really close.

Thanks for that explaination, Doc!

I have a question about Dead pixels..

Do they show up in screen shots? When it first happened, I quickly took a screen shot to take a closer look, and realized it wasn't in the screen shot. If they are (the dead pixels) maybe it just some type of interference within the monitor? (yes, my monitor is as clean as a whistle, although I think there is a scratch on it..).

No, you won't be able to capture them in a screenshot (/me chuckles), all you could do is try to take a photo

The screenshot takes a "picture" of what the PC/vidcard calculated, not of what the electrons display when they hit the phosphor on the monitor front.

You could try different res, see if the dead pixel stays in the same spot.

LOL, Ok. Thanks, I may try that.
