what is a dead pixel? Is it a certain color sticking? There has been alot of talk about it but I am not sure what a dead pixel is or how serious it is.
For example if I had a dead green pixel in the center of my screen, if i opened WORD would there be a green spot right in the middle of my document if I had a green background/picture there would be a hole in the middle of it? Aren't pixels small. Does anyone have a picture or link to pictures of computers with dead pixels?

Also I am most likely ordering my computer through my college do they check pixels for me. Has anyone ordered through their school? Is it easier or harder to return them with the school?

LCD monitor dead pixel guide

What is a dead pixel?

What is a dead pixel?
"A pixel on an LCD monitor that remains unlit, or black, when it should be activated and displaying a color. Each pixel on an LCD screen is made from three separate subpixels—one red, one green and one blue—that when combined form the colors that the users see on the monitor. A dead pixel occurs when the transistor that activates the amount of light that shows through all three subpixels malfunctions and results in a permanently black pixel. Dead pixels are rare and largely go unnoticed by the user. "
You can always have STUCK pixels in which they always stay a certain color, (Red, green, blue). If you had a stuck green pixel and opened word you'd have a tiny green spot right in the middle of it. If you opened something green it'd look normal. If you have a dead pixel you'd have a tiny black spot there no matter what you do. A pixel on an LCD monitor that remains unlit, or black, when it should be activated and displaying a color. Each pixel on an LCD screen is made from three separate subpixels—one red, one green and one blue—that when combined form the colors that the users see on the monitor.

Dead pixels are rare and largely go unnoticed by the user. To see what a dead pixel looks like, go to Accessories -> paint. Then go to Image -> Attributes. Make the image 1x1 pixel and you'll see what one pixel looks like. It's quite small. It'll be whatever color your background color was. Make it green, red, blue, black and you'll know exactly what it'll look like.

It's difficult to catch a dead pixel on camera but it'll look just like an extra period on your display somewhere. It'll probably be even smaller than a period.

Your college will not check for dead pixels for you as they're a tolerated part of the manufacturing process. I'm not sure whether it'd be easier or more difficult to return them from your school.

Dead Pixel - will never light (always black)

Stuck Pixel - Pixels are made of Red, Green, and Blue sub-pixels. A stuck pixel occurs when one or more of the sub-elements is always on. If all three sub-pixels are stuck there will be a white pixel always on.

Stuck pixels are sometimes not visible because the part of the image they display requires them to be on anyways. I have a red and a blue stuck pixel, but I usually don't see them in word (because these pixels must be on to make the white background of the page).

Depending on where the pixels are, they could be a huge pain. mine are in the lower corner so they don't generally interfere. But sometimes I can see them If this was my main gaming machine I'd be mad.

So, as a poster said the reason why people should send computers with dead pixels back is because there are thousands of others who pay the same price and have no dead pixels. However how many of us are looking for them? I mean if they are so rare do you think the forum will have people constantly looking for pixels? Unfortunately or maybe not I know if I get one I most likely will look. However I guess what I am trying to say is do other computer s have the same amount of dead pixels new?
At the same time this is a forum on a specific notepad and honeslty I guess I woud like to hear about dead pixels and any other errors so this is just a thought. Disregard it as serious.

I don't think most people look for defective pixels - they just jump out at you when you are working on something and notice a bright dot that shouldn't be displaying.



I do not think other brands of notebook computers are more or less suceptible to defective pixels than ThinkPads. IBM and other manufacturers (like Dell, Toshiba, Sony, HP/Compaq, Apple, etc) buy their panels from manufacturers who specify that a certain grade of panels may have up to a certain number of defects per panel.

i say, if you don't know what a dead/stuck pixel is, then you don't need to worry about it. ignorance is bliss.

Thanks Alot guys.
