There is a program called "Dead Pixel Buddy" that I use (http://www.laptopshowcase.co.uk/downloads.php?id=1)

You can also use the PC Doctor program. I got PC Doctor with my T42. If you have it go to Video test, and then test the default monitor. However this test doesn't test the edges, while the "Dead Pixel Buddy" does.

Personally, closely inspecting an all-white screen then an all-black screen does it for me...if I don't see a problem then there isn't a problem...why go looking for one!

slagmi:

Because A. Some stores, like IBM direct, let you return the product within the first 30 days, but on the other hand have a non acceptable dead pixel coverage under the warranty agreement. So it is good to find out the problems before the first 30 days.
And B. because some time a pixel can act out strange. I have such a pixel see my post "Help: strange pixel" and having different screen colors helped me to see the nature of the problem, and decide that it is software related and not hardware i.e. my LCD is OK, but some program has a bug. So B is for a better diagnostic power.

slagmi I agree if the pixel is black somewhere in the cornes ... but imagine the purple or light green big one in the middle of your screen playing honky tonky with your nerves ..

The hackers at heise.de have published 'ctscreen', a nifty little Java utility to assess the quality of CRT- and LCD-screens. Grab it here.

One of its features provides the pattern mentioned in this article.

yea I see your point, especially if you're within 30...

personally, I deal with computer problems on a daily basis perhaps that's why I don't go looking for problems...

I'll try an all-white screen and an all-black screen and if there's any doubt maybe all blue, green or red. If things look OK I'm satisifed. knowing about a defect I never could see before would probabally just bug me.

Yeah, [censored] those young whippersnappers and their good eyes!

No, really, ctscreen comes in mighty handy when you're in the market for a used or new CRT or LCD screen or a laptop (unless you can take advantage of the extra service provided by certain vendors).

Beyond that, the old rule of software engineering applies: "Don't test for conditions you don't know how to handle!".

Insert smileys where appropriate, cheers,
