Monitor Test

Comprehensive Display Testing

The Monitor Test tool provides a comprehensive suite of visual checks to evaluate your screen's quality. By cycling through solid colors like red, green, blue, white, and black, you can easily identify dead pixels or stuck pixels. Advanced tests including gradient displays and color banding patterns help you detect subtle inconsistencies in color transitions. The grid pattern is specifically designed to reveal sub-pixel issues, ensuring your monitor performs at its peak potential for any visual task.

Secure Browser-Based Analysis

Your privacy is a top priority, which is why the Monitor Test tool operates entirely within your web browser. No data is ever transmitted to external servers during the testing process. The application runs locally on your device, ensuring that your personal information remains private while you perform technical checks. This makes it a fast and secure way to diagnose hardware issues without needing to install additional software or share any telemetry with third parties.

How can I check for dead pixels?

You can identify dead or stuck pixels by switching through the solid color modes, such as red, green, blue, white, and black. These high-contrast colors make it easy to spot any individual pixels that are not displaying correctly or are stuck on a single color across your entire screen.

Does the tool support fullscreen mode?

Yes, the tool includes a dedicated fullscreen mode for more accurate testing. By entering full-screen, you eliminate distractions from your browser interface and operating system elements, allowing you to focus entirely on the display patterns and detect even the smallest imperfections in your monitor's performance.

Is my personal data safe while using this tool?

Yes, your data is completely safe because the tool runs locally within your browser. No information or telemetry is sent to any external servers during the testing process. The analysis happens entirely on your machine, ensuring that your privacy is maintained while you perform your monitor's hardware diagnostics.

How do I switch between different test patterns?

You can easily navigate through the various test modes using the arrow keys on your keyboard. Simply press the left or right arrows to cycle through options like gradient, color banding, and grid patterns. To exit the fullscreen mode at any time, just press the Esc key on your keyboard.
