Frequently Asked Questions

How often should I test my screen?

We recommend monthly checks for professional use, or whenever you notice display issues. Gamers and graphic designers might want to test more often.

Can this fix dead pixels?

While we can’t fix dead pixels, our tests help you find them and decide if you need repair or replacement. Sometimes, gently massaging the area around stuck pixels might help – but be very careful!

Do I need special equipment for the screen test?

Nope! Just your device and browser – we handle everything else. Our tests work on any display, from phones to big monitors.

How long do the tests take?

Each test takes 2-3 minutes. Do them all for a complete check, or pick specific tests you need. The full suite of tests takes about 15-20 minutes.

Will the color test work on any monitor?

Yes! Our color test works on all types of displays – LCD, LED, OLED, and even older monitors. It’s great for checking both basic and professional displays.

What’s the best way to use the gradient test?

Look at the gradients from about arm’s length away. If you see clear bands or strips in what should be smooth color transitions, your screen might need calibration.

Can I test my laptop screen and external monitor differently?

Yes! Run the tests on both screens separately. Pay special attention to color matching if you use them together.

How accurate is your response time test?

Our test gives you a good general idea of your screen’s performance. While not as precise as professional testing equipment, it’s great for spotting obvious issues.

Should I do the uniformity test in a dark room?

A dimly lit room is best for the uniformity test. This helps you spot any uneven lighting or backlight bleeding more easily.

What if I fail the text clarity test?

First, make sure you’re using your screen’s native resolution. Then check your cleartype settings (Windows) or font smoothing (Mac). Sometimes, a driver update can help too.

Can I use this to test my TV screen?

Yes! Just open our website on your smart TV browser or connect a laptop to your TV. Great for checking color accuracy and screen uniformity.

Will the contrast test work in a bright room?

While the test will work, you’ll get better results in a moderately lit room. Bright light can make it harder to see subtle differences in contrast.

How do I know if my gamma settings are right?

During the gamma test, all the gray squares should be visible. If some blend into the background, your gamma might need adjustment.

Is it normal to see some color shift in the viewing angle test?

Yes, most LCD screens show some color and brightness changes when viewed from angles. OLED displays typically perform better in this test.

Can I test multiple monitors at once?

While you can run tests on multiple monitors, we recommend testing one screen at a time for the most accurate results.

What if I see the screen flickering during the tests?

Some flicker is normal during specific tests like the response time test. However, if you see flickering during static images, check your refresh rate settings.

Do I need to warm up my monitor before testing?

For the most accurate results, let your display warm up for about 20 minutes before testing, especially for color and uniformity tests.

Can this help me calibrate my screen for photo editing?

While our color calibration test can help you improve your settings, professionals might still want to use hardware calibration tools for perfect accuracy.
