Lcd tv dead pixel free download - InjuredPixels: Dead Pixel Test, Pixel Force: Left 4 Dead, Dead Pixel Tester, and many more programs. Your LCD monitor is made up of millions of pixels. Each pixel is a group of the colors red, green and blue subpixels that combine to make any color needed and they create the images you see on.
If this is an LCD screen look closely at the screen and see if you can see where it actually starts if you can find it take a pencil with an eraser on the end and place the eraser on the spot were it starts and apply a small amount of pressure a little at a time and release. Do this a few times or until the line goes away. Lines can be made by dead pixels. A small amount of pressure on the LCD can fix this, be careful not to use anything sharp.
This does not work with plasma or LED screens. Hope this helps. If the lines are appearing and disappearing then it is not dead pixels you are dealing with but it could still be related to pressure.If you are careful you can troubleshoot the problem yourself.
