Also available for Android

Introduction

InjuredPixels allows you to easily check for defective (hot, dead or stuck) pixels on LCD monitors.

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. InjuredPixels can be run directly without having to install it on your computer: just download the portable version and run.

The Menu

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

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

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

InjuredPixels for Windows Help - The Main Menu Screenshot

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.
