How to check your LCD for DEAD PIXELS.

Hey guys I found this very useful website that allows you to check your lcd screen for dead pixels by using a variety of color background tests.

I found one white pixel on mine, If it hadn't been for this site I would have never known.

Test your LCD's and check back with results.

Thanks. Though I found more dirt than dead pixels

 

Crap... It turns out it's not ONE dead pixel , but a small group of FIVE!
But it's really hard to tell that they are there, unless I do the pixel test.
What is Dells dead pixel return policy?

 

I was about to say, you shouldn't use it really because you might become fixated on it. though its EXTREMELY understandable that you might want to get the best screen possible so that you could tell dell about it. thanks for posting this cell

 

Download a free program called "dead pixel buddy".

Check.

 

I tried that one, but doesn't work as well as the website version I posted, dead pixel buddy showed my screen with ZERO visible dead pixels. Check for yourself, maybe you'll get a nice surprise!

I'm still searching for Dells most recent dead pixel return policy...
I know that when using normal desktop applications that I can't notice it, but what bothers me is that the dead pixels are right smack in the middle of the screen! If it was on the edges then I it would be more tolerable.

 

i found 0 dead pixels on my 3 year old laptop
go Dell

 

I just found 0 dead pixels on my six year old Compaq Armada 110.

I am NOT going to use this website when I get my Inspiron 1520. I'm scared I will find a dead pixel and then I'm going to see it everytime I use the computer. And I don't have time to send it back.

 

Ignorance is bliss! I'll probably do the same when I receive my 1420.

 

Yep, I'd rather not notice if I have 5 dead pixels and be happy

 

Like I said, the dead pixels are not noticeable at all during use... but maybe this issue might earn me a good ol' discount from dell.

 

Yep. The only thing I managed to find was dirt and dust on the screen. Woo.

 

so it seems that I am the only one that is affected

 

Either that or you are doing something wrong, like seeing dust. But seriously, how would you NOT see the dead pixels outside of the stupid checker thing?

 

I honestly dont see the point in these type of programs. 95% of people dont even realise they have dead pixels until they use this program and when they do find out they will just worry themselves. If you cant notice any before the test then dont do the test, you'll just regret it as your more likely to notice it once you realise its there. Do you self a favour and dont bother using this program unless you can already see dead pixels on your screen.

 

Maybe u didn't look close enough. Either one work the same way, there really no difference b/n the two.

 

I keep getting dead pixels confused with dirt. Lol, I think I see one and I'm look "oooo dead pixel!" I touch it with my finger... nope nevermind. I can't find any, lmao.

 

make a complete black picture and complete white picture, show them full screen. If you really have a dead pixel, you'll find a white, red, or green spot. If not you are doing something wrong. The chances of having dead pixel in modern laptops are very rare.

 

I can assure you it is not dust...

 

try dragging the windows around the screen, check what you see..

 

Nice to know, 100% perfect :>

 

What's the point? I've already told you, both methods work in the same way. If you didn't see anything with DPB, it was because u weren't too careful enough.

 

I quadruple checked it with dpb. and shows no signs of dead pixels with it.

 

I still don't see how DPB would be less effective. If anything, DPB has the advantage of actually doing full-screen w/o the borders in web browser u need to use ur site. Maybe ur problem is that you can't really see well and uniform color in DPB messes with ur mind... or maybe the patterns in the site you've linked are messing with your eyes :laugh:

 

Zetto, I'm thankful to say that my vision is very good indeed.

 

well, that leaves ur brain to be the culprit :laugh:

 

Sure thing dude

 

haha...very funny...

 

Remember, a stuck pixel is a pixel stuck on a color.. a dead pixel should show as a black dot against bright backgrounds. Stuck pixels are way more annoying than dead pixels. My new 1420 has 1 dead (black) pixel.. but I never notice it or care about it enough. I've seen LCDs have a bright green or red pixel and thats always noticeable and very annoying.. I'm just glad I don't have any like that.

The good news is that there's a chance the pixels can become "unstuck" and start to function properly.. there's even programs you can download that will "exercise" the LCD by flashing random full-screen colors to try and unstick any pixels. I've never seen a pixel fixed like this but it's worth a shot.
