For any kind of LCD damage on the monitors of a PC
, the dead pixels can be restored by using UDPixel freeware helping detect the pixels
that are failing and restoring them back to working order. This freeware
works by sending color flashes onto the chosen target area. Three sub-pixels form a single pixel
imparting 16777216 colors per pixel. If all of the three subunits go defective, then the respective LCD runs completely out of service. The 'UDPixel22_installer.exe' file downloads and runs the freeware
for restoring the dead pixels. The warranty provided by the manufacturer is not applicable for 0.01% or fewer defective pixels. The possibility of replacing the defective LCD monitor
exists only if an unnecessary pixel series
is found to be evident right in the middle of the screen.
You've had your LCD computer screen for a while and it is now starting to fail. There are bright or dark spots that have appeared on the surface of your screen. Don't worry: there's still a chance that you won't have to buy a new one.
A pixel is basically made up of three sub-pixels (red, green and blue RGB). Each of them can display up to 256 levels of light, giving 16 777 216 colors per pixel (256x256x256). A single sub-pixel can be defective, but if all three are out of service, the pixel itself is dead. It is either off or emitting light permanently.
UDPixel is a freeware that will help you detect failing pixels and get them to work properly again.
UDPixel send flashes of color on a targeted area that you have chosen.
Downloading and installing UDPixel
- Click on the link http://udpix.free.fr/index.php?p=dl
- Note that the software is available in an English version
- Once downloaded:
- Double-click the icon "UDPixel22_installer.exe"
- Click on Run
- Uncheck the box Run at Windows startup UDPixel
- Click Next
- Click Install
- Click Close
- Click Start/ All Programs/ UDPixel/ UDPixel
- Locate the dead pixels by clicking on the different colors
- Click start
Note that the manufacturer's warranty does not work if 0.01% or fewer of the pixels are defective. This gives:
- 15 "(native resolution 1024x768px) up to 78 pixels.
- 17 "and 19" (native resolutions 1280x1024px) up to 130 pixels.
- 20 "and 21" (native resolutions 1600x1200px) up to 192 pixels.
- 23 "and 24" (native resolutions 1920x1200px) up to 230 pixels.
If your screen has fewer defective pixels than noted above, the manufacturer will point out that 99.99% of the device functions normally and may refuse to change your monitor. Fortunately there are some exceptions, for example if you have a series of useless pixels in the middle of the screen, you may still get a new one. Some manufacturers set an upper limit, by native resolution, typically between 4 and 20 (for screens from 12 to 21 inches).
Finally, note that the experiences of users employing this software are very different, and while some require only a few minutes to resuscitate the pixel, for some it may take a whole day.
