Dead Pixel Test & E-Ink White Wallpaper
Check ordinary displays for dead or stuck pixels, or generate a pure white wallpaper for an E-Ink device.
Dead Pixel Test
Show solid colors across the screen to make individual pixel problems easier to spot.
Before entering full screen: colors cycle White → Black → Red → Green → Blue. Use the Left/Right arrow keys or click anywhere on the screen to change color. Press Esc to exit full screen.
E-Ink White Wallpaper
Generate a pure white PNG at the exact pixel dimensions you need, then transfer it to your E-Ink device.
Dead Pixel and Stuck Pixel Test
Solid white, black, red, green, and blue screens can make pixels that remain dark, bright, or stuck on one color easier to notice. This is a visual check rather than a hardware diagnostic.
Pure White Wallpaper for E-Ink Devices
Some E-Ink devices work well with a simple pure white image as a wallpaper or screensaver. Enter the exact width and height of your device and QuickEasyKit generates a white PNG locally in your browser.
Why Use the Exact Resolution?
A wallpaper with the same pixel dimensions as the target display can avoid unnecessary scaling and help the image fit the device as intended. If you know your device's native resolution, use Custom Resolution rather than guessing.
Private, Browser-Based Processing
The screen test and wallpaper generation run locally in your browser. No image upload is required.
FAQ
What colors should I use for a dead pixel test?
White, black, red, green, and blue provide a simple basic check for different pixel and subpixel problems.
Can I make a wallpaper for any E-Ink device?
Yes. Enter the device's required pixel width and height. The generator creates a pure white PNG at those dimensions.
Does the screen test repair a bad pixel?
No. It only helps you identify pixels that look different from the surrounding display.
