Every pixel in focus
Pixel Tester
Check your display for dead pixels and uneven backlighting. Nine colors, fullscreen, and simple controls.
About the project
A tool for inspecting a desktop or phone display without installing an app. The test uses pure color fills, with no gradients, decoration, or transitions that could obscure a defect. Keyboard, mouse, and touch controls disappear when not needed, while fullscreen adapts to the browser’s capabilities.
Current state
A working nine-color display test with true fullscreen and responsive controls. Color shortcuts keep the display clear; moving the mouse or tapping restores the controls. Where Keyboard Lock is permitted, the first Escape hides controls and the next exits fullscreen. The tool helps you spot defects visually; it does not detect or repair them automatically.
