    LCD Monitor


    Not sure if this is the proper place to post this

    Hi,

    I just purchased a new 22'' LCD monitor and found that one of the pixels was on "bright green". Now I looked at this pixel and rubbed the area where it was just to be sure it was indeed one of the pixels and it switched back to working properly....So should I leave it alone or should I take it back to the dealer and state that one of the pixels was malfunctioning but is working O.K. now?

    I guess what I'm asking is, is this going to be an ongoing problem...Note I have a year warranty.

    Normally, those "dead pixels" are not covered by the warranty (at least with majority manufacturers, due to "technology limitants of LCDs" or something like that)

    I can be found either 40 miles west of Chicago, in Chicago, or in a galaxy far, far away.

    To expand upon hugotega's reply: LCD manufacturers only warrant their displays if there are more than some number of bad pixels. One is not enough to reject the unit. After all, one of 1 million + pixels is only about 1/10000 of a percent, or less... Almost not enough to measure! In your case, since "rubbing" the display "fixed" the problem, I think you will have to live with the "finger swipe" workaround.
    Sometimes, real fast is almost as good as real time.

    often times the warranty only covers it when there are a bunch in a certain small area like a 1"x1"

    Thanks for the replies

    I'm going to monitor the situation(no pun intended) because right now the monitor seems to be working fine even with the missing pixel...To tell you the truth I don't think I could find the pixel again...

    I don't know if this really works, but a while ago I've found that some people say that random "noise" video ("noise" meaning just random pixels, like an old tv not tunned in any channel) is able to "resurrect" dead pixels more safely than the pressure method (which I've read risks "killing" more pixels).

    Basically you got to just leave it there for a while, I don't remember how much time they've estimated that it's supposed to be enough. Actually I think that even the people who promote this do not say that it's 100% confirmed, but they have some "theory" on how it works, and as a layman, it didn't sound stupid.

    Unfortunately it definitely does not work for entire dead columns, which is another thing entirely, and basically means that you have to replace, either the screen or the monitor.

    There's a site which provides this sort of video for free, as a javascript in a pop up window.
