Overview of InjuredPixels

InjuredPixels can be used to check for dead or defective pixels on LCD monitors.

A defective (hot, dead or stuck) pixel is a pixel that does not illuminate properly or does not display the correct color output. It usually looks like an annoying black, white or colored spot on your screen. (For more information read this Wikipedia article.)

InjuredPixels can be used to test a new LCD monitor before purchasing, or an already purchased monitor during the warranty period (as you may get a replacement according to the manufacturer's dead pixel policy).

InjuredPixels fills the entire screen with a primary or custom color, allowing you to inspect the screen for pixels that do not match the selected color. The program is easy to use: click or use the arrow keys to cycle through colors or right-click to get the menu with the main commands.

Starting InjuredPixels

To start and use InjuredPixels, no installation is required: simply click on the download link, save the program file to a location on your computer and then open/run the file.

The Pop-up Menu

The pop-up menu contains items that perform the main actions of InjuredPixels.

To open the pop-up menu, click the right mouse button anywhere on the screen, or press Enter, Esc or the Menu key on your keyboard. The pop-up menu is automatically opened when the program starts.

To close the pop-up menu without selecting any item, click the left mouse button anywhere on the screen, or press Esc on your keyboard.

Black

Click this menu item to change the screen color to Black (#000000). Hot or glowing pixels (permanently lit white pixels) or stuck pixels (pixels with one or two sub-pixels always on or always off) are usually best seen against a dark or black background.

White

Click this menu item to change the screen color to White (#FFFFFF). Dead pixels (defective pixels that remain unlit) are usually best seen against a white background.

Red

Click this menu item to change the screen color to Red (#FF0000). Red is one of three sub-pixels which produce the visible color of the pixel by their relative brightness.

Green

Click this menu item to change the screen color to Green (#00FF00). Green is one of three sub-pixels which produce the visible color of the pixel by their relative brightness.

Technical note: InjuredPixels uses the primary Green color of a RGB display (#00FF00), that corresponds to the Lime Web Color and it is different from the Green color defined in HTML specifications.

Blue

Click this menu item to change the screen color to Blue (#0000FF). Blue is one of three sub-pixels which produce the visible color of the pixel by their relative brightness.
