    as far as lcds are concerned, all manmufacturers state the minimum number of pixels that must be dead before they will take any action. refer to your manual/warranty agreement.

    How does one test a new monitor for dead pixels?

    Look at the screen...

    Go into paint (or similar) and create a pure white image that covers the entire screen. Now if you see any pixel that aren't white, it has a defect. Now invert the colour of the image (so that it turns black) and see if there are any pixels that aren't black.

    These are dead pixels. To get a new monitor, there has to be a certain amount of dead pixels within a certain radius, otherwise you're out of luck, unless your manufacturer has a special "no dead pixels" warranty.

    There is a way to turn off "dead" pixels, where you download a program and select which pixels you want to turn off... I'm sorry, but I don't remember the name. And even when you've done that it will still look out of place, but hopefully not as much as before...

    For more info search for information about an ISO standard for lcd's...

    I believe Rick once said that sometimes by gently massaging the screen surface where the dead pixel is located sometimes fixes it. Worth a shot I'd say.

    True, I'd forgotten about that. Use some sort of cloth underneath so you won't make any scratches. Also, be careful in how much pressure you assert, as too much can "kill" other pixels, but then again, too little won't have any effect.

    Keep up the massage for about one minute, just moving your thumb slowly around over the area of the dead pixel. If it doesn't work the first time, try with a tiny bit more pressure (but keep in mind it's electronics underneath you don't want to damage) and try again. If it still doesn't work, it truly is dead.
