How to: test/check your monitor for dead pixels

| November 26, 2009 | 0 Comments

TFT screens have thousands of pixels, on a 1024×768 monitor, there are three cells for each pixel – one each for red, green, and blue – which amounts to nearly 2.4 million cells (1024x768x 3 = 2,359,296).

In most cases, a stuck or dead pixel is impossible to fix (some people rub them gently with a cloth etc. search the net for other ways), however most manufacturers have a policy which will specify that after X amount of dead/stuck pixels they will replace the screen free of charge (in warranty period).

You can use DPT to help identify IF you have any pixels and how many in order to see if you qualify for a replacement screen/laptop.
