dark pixels!

[pseven]

i have a new laptop and there are dark pixels. the pixels are not off or stuck they are just dark, what is up with that? does anyone know what is the problem. attached is a pic of the problem at about 40X (i work in a bio lab so i have access to neat microscopes )

The actual pixels seem to be ok. Looks like there's something before them, scratches or dirt.

Factory defects. Happens alot actually.

See your crosspost for my reply. Now that I have realized that this is a 40X magnification, I agree with other posters on the problem diagnosis, but still, my suggestion for warranty work or replacement still stands.

-if i have a 40x magnified picture of the screen, dont you think that i would be able to tell if it were a scratch or dirt? i assure you all that it is neither.

as for being a factory defect, is it possible for this to be a rescent problem. i got the laptop in september and these spots have appeared within the last month.

It depends on how you did your focusing.

From looking at diamonds at 40X, I have learned that things that aren't exactly the same distance from the lense as each other won't be in focus at the same time. The center of a bad diamond (with "inclusions") might look nearly perfect when you focus on the surface; and then again, if you focus on the center, you'll not know how clean the surface is.

In other words, the possible "scratch or dirt" on your screen would be much closer to your lense than the pixels themselves, and therefore would be completely out of focus when the pixels themselves are in focus.

You may have already been aware of that, and you may have already tried refocusing because of this. I just posted this because I didn't know if you were aware/tried it yet or not.

Hope this helps.

My guess would also be dirt that has gotten sandwiched between the layers of plastic that sit in front of the LCD/TFT panel that forms your display. Your microscope seems to be focused on the pixels in the background though, rather than the dark spots in the image - if you shift th efocus out a little, what do you see??

LOL! yes i am aware of the focusing depth, but thanks for the post. The trouble is, the dark spots are not soild in colour, its hard to see in the pics.it looks as though they are from stress, if any of you have taken any plant anatomy classes, they look like tannins that can be found in the flesh of dates... that reference may have been a bit obscure but that is what they look like! anyway, its not a scratch or dirt, is it possible that the supports that hold the 2 pieces of plastic apart have been crushed? does this happen?

[swingdjted]

That's beyond my knowledge of computer screens. Someone that knows more about them than me would have to answer that. So I guess you should just disregard this post since I didn't really say anything helpful...

i'm pretty sure that may happen or something similar, i know LCD screens are supposed to be senstive to being dropped/crushed or even touched too hard sometimes...

now whether that's enough to make the kind of thing your describing happen, i have no clue.

Can you feel anything at all different about the surface when you touch it? It looks like the outer layer is coming into contact with the inner layer and keeping it from lighting properly. Notice that the darkness follows canyon-like shapes, getting darker the further "in" you go.

My dell laptop LCD has a slightly brighter circle in the center of it from the stupid Dell logo circle on the other side of the monitor being pressed down into it while being transported in my bag...

I don't know what could cause dark sports like that though.

[pseven]

i give up, there is no finding out what it is.... gah!!

Same story here with a Compaq.

My older Compaq (much older - P1 MMX processor) has a flat case without that raised circle we're talking about - screen looks good as brand new.

That thing can still run Win 98 SE, winamp classic, browse the internet, and pull networked media off the other computers, even after being dropped. Drop a 'today's computer' and you're fucked.

the torision stress between the edges of the screen and the resistance put up by the laptop screen hinges probably caused these marks.

laymans terms? the concrete in a suspention bridge during an earthquake or extreme winds will crack. twist a piece of plastic hard enough, stress marks and fractures will form. etc.

i personally always open the laptop from the middle, to try and reduce torision stress, as opposed to the corners. apply uneven pressure between your hands, you twist the screen. i'm getting redundant. sleep time.

actually my friend dropped his Dell (similar model as mine) down a flight of stairs once. Didn't seem to phase it. He, of course, shit his pants on the spot.

i have a Mac powerbook, i push a button aht the scren pops right up. no worrying about uneven pressure.

This compaq (with the problem) has a lever that unlocks it open in the center, which helps people to always open from the center. I think the problem is mostly from being in the bag where occasional pressure causes the circle in the center (where the brand name is) to push on the screen.
