Space Voyager Posted January 5, 2009 Share Posted January 5, 2009 After I first spotted a bluish dead pixel on my new laptop I simply thought that there is nothing I can do. Than I finally realized that this dead pixel is sometimes there and sometimes not... After some Goggling I found implications about bad video card memory that probably causes it. I'm taking the comp to be serviced and I want any possible solutions to this problem. Is there any other way to get virtual dead pixels? Link to comment Share on other sites More sharing options...
Slaughter Posted January 5, 2009 Share Posted January 5, 2009 Are you it's sometimes not there? In some cases you will just have a hard time seeing it with some backgrounds, but see it easily with others (related to what colour it is etc.). Most manufacturers of LCDs does not replace the LCD with only one dead pixel. Policy varies widely... As for the "virtual dead pixel", I've not encountered that working support ever. I see it mentioned in forums as you say however, so if the pixel is only sometimes dead that's a likely solution. Don't have any other possible reasons for you, but I'd suggest you get hold of a memory test program to check the video card memory. Also keep in mind that most notebook video cards use parts of the RAM as video memory. This means that it could also be the RAM, and not the video memory. Memtest is nice for testing RAM, but not sure if it also tests the video memory: https://www.memtest86.com/ Link to comment Share on other sites More sharing options...
FullAuto Posted January 5, 2009 Share Posted January 5, 2009 Sounds like a truly dead or dying pixel. Sometimes it turns the right colour, sometimes it doesn't, until it sticks on one colour, and changes no more. I'm able to put up with them as long as they're not a bright colour. Having a lime green pinhole in your image can really put you off, however. Link to comment Share on other sites More sharing options...
Gimli Posted January 5, 2009 Share Posted January 5, 2009 Have you tried one of these? There are other programs that do the same thing. Link to comment Share on other sites More sharing options...
NKF Posted January 5, 2009 Share Posted January 5, 2009 My first laptop had a red pixel, but it was also elusive and not always there. When it was red again, I somehow discovered that pressing the edges of the screen would turn it back to normal - or worsen it. In this case, I assume that it may have been a problem with the circuitry for the individual row/columns not contacting properly. It eventually went away, but then the whole screen started to go a red hue as the laptop started to age. But I guess 2 - 3 years is a long time for laptops that were made with technology circa 2000. - NKF Link to comment Share on other sites More sharing options...
Slaughter Posted January 5, 2009 Share Posted January 5, 2009 One can actually "massage" dead pixels back to life in some cases. Of course, one can also damage the LCD further, so it's far from risk free Link to comment Share on other sites More sharing options...
Bomb Bloke Posted January 6, 2009 Share Posted January 6, 2009 I tap 'em with the very tip of my fingernail. It usually works, but odds are the pixel will "die" again within about ten minutes. I've been lucky with my particular screen... Had it a couple of years or so by now, no blemishes at all. Link to comment Share on other sites More sharing options...

I've been staring at the screen for quite some time before I was certain... It is a light blue pixel on a black background and it is annoying - when it is there. @Gimly: Thank you, I will definitely take any available option to even get rid of it! Didn't think it was possible... I'll take the comp to be serviced anyway (the battery died in a month!), so I'll ask them as well, but your option may well be the only one. Oh, and BBs nails.

Gimli Posted January 6, 2009 Share Posted January 6, 2009 It is suggested that you use a ballpoint pen instead of nails. You'd need to be careful not to do more damage, so I suggest googling for instructions. I don't have the guts to try something like that. Link to comment Share on other sites More sharing options...
NKF Posted January 6, 2009 Share Posted January 6, 2009 One possible cause for the red pixels is stress. That is to say: the whole process of opening and closing the laptop screen, and the way they are designed to offer a little resistance so that they stay upright in any position you choose. Of course that points to sloppy manufacturing. Unfortunately, not closing your screen forever does defeat the whole purpose of having a laptop! - NKF Link to comment Share on other sites More sharing options...
