Screen Color Test

The screen color test allows you to display pure, solid colors across your entire monitor. By removing all distractions and UI elements, you can closely inspect how your monitor reproduces the primary (Red, Green, Blue) and secondary (Cyan, Magenta, Yellow) colors. It's an essential diagnostic tool for both new and aging displays.

Why Test Solid Colors?

Testing solid colors helps you identify two major display defects: stuck pixels and screen burn-in. A 'stuck' pixel is a single dot on your screen that is permanently locked to red, green, or blue. You might not notice a stuck blue pixel on a white background, but it will stand out instantly on a pure red or green background. Burn-in, common on OLED and older plasma displays, appears as faint, ghost-like silhouettes of UI elements that are permanently etched into the screen, which are often easiest to spot on solid gray, magenta, or yellow screens. Utilizing standardized browser benchmarks eliminates the guesswork from troubleshooting, giving you real-time data to optimize your setup without third-party software.

How to Use This Tool

Clean your screen first with a microfiber cloth so you don't mistake dust for dead pixels. Enter fullscreen mode and either manually click through the colors or use the Auto-Cycle feature to let the tool switch colors every 2 seconds. Look closely at the screen from different angles on every color to spot any anomalies. Whether you are fine-tuning hardware parameters, calibrating settings, or inspecting for defects, our tools run with sub-millisecond precision directly on your device.
