dead pixles

[JohnDoH!]

How do you tell if an lcd monitor has a dead pixle or not? is it clearly visible? or do you need some sort of program to tell you if it has any?

A dead pixel on an lcd will stand out after a period of time when it remains a constant black spot while other colors are seen everywhere else. A single pixel will be a small square area not much over the size of the head of a pencil. That's a steady dead area of space on the monitor itself with no software designed for this. Manufacturers have their own diagnostic tools to see if a monitor is functional but not for dead pixels on the display itself.

If you can't see a deadpixel there probably isn't one...And if there is one and you can't see it, well consider yourself lucky

They can be black, or red, or blue, or yellow. They have some programs out there which show a single color on the entire monitor, making it easier for dead pixels to appear, and they have the option to try and fix the dead pixel.

There's a big difference between stuck pixels and totally "doa" pixels. If there are any visible there is a freeware for refreshing ones that stick in order to get them moving again called JScreenFix that's been around for a few years. You can download that from http://www.fileboost.net/directory/desktop/screensavers/jscreenfix/032783/review.html But if there's a bad element in the display even this is worthless. The reflective material in the display screen itself is ....ggggggone... The other tool you are mentioning has to do with the emitter not the reflective overlay.

thanks for that program, i'm gonna bookmark that incase i ever come across a bad display.

i've freaked out a few times before, only to find that my 'dead pixel' was nothing more than a flake of dust

When lcds were first coming out with the 17" and larger screens a few of those types of diagnostic and repair tools were seen. Now they are hardly even mentioned with the improvements later made on many makes and models. Some of the earlier models had their day of troubles where those came in handy at times.
