Frequently Asked Questions

What are dead pixels and stuck pixels?

Dead pixels are pixels that do not display any color, appearing as black dots on all backgrounds. Stuck pixels are those that are fixed in one color and do not change regardless of the displayed content.

How do I use the screen test tool?

To use the tool, click on a color test to enter fullscreen. Carefully search for any pixels that do not align with the color shown. Use the arrow keys to switch colors and press ESC to exit. Testing in a dark room produces the best results.

How often should I test my screen?

It's recommended to test a new monitor right after purchase and then conduct maintenance checks every 3-6 months. When you notice display anomalies or suspect pixel issues, you should also perform a test.

What should I do if I find dead pixels?

If you discover dead pixels on a new monitor, your best action is to contact the manufacturer for warranty service or replacement options. Minor stuck pixels may sometimes be addressed using pixel-fixing software, while severe cases might require professional repair or replacement.
