Monitor Test FAQ
Frequently asked questions about monitor testing
What monitor tests are available?
Our comprehensive suite includes 17 different tests: Test Patterns, Pixel Test, Uniformity, Contrast Ratio, Backlight Bleeding, Color Accuracy, Color Gamut, Gradients, Sharpness, Viewing Angle, Gamma, Response Time, Overdrive Testing, Input Lag, Refresh Rate, HDR Testing, and Burn-in Testing.
How do I use the monitor tests effectively?
For best results, use fullscreen mode (F11), ensure proper room lighting, view from your normal working distance, allow your monitor to warm up for 30+ minutes, and clean your screen before testing. Each test includes specific instructions and controls.
What should I look for in pixel tests?
Look for dead pixels (always black), stuck pixels (always one color), or hot pixels (always white). These appear as small dots that don't change color with the test pattern. Also check for sub-pixel defects and color uniformity issues.
Do these tests work on all monitor types?
Yes, our tests work on LCD, LED, OLED, QLED, gaming monitors, professional displays, laptops, tablets, and smartphones. Some tests like HDR and high refresh rate are specifically designed for capable displays.
Can I test gaming monitor features?
Absolutely! We have specialized tests for gaming monitors including refresh rate testing (60Hz, 120Hz, 144Hz+), input lag measurement, response time evaluation, overdrive testing, and motion clarity assessment.
Are the color accuracy tests professional grade?
Our color tests cover sRGB, Adobe RGB, and DCI-P3 color spaces with gamma testing and gradient evaluation. While suitable for most purposes, professional color work may require hardware calibration tools for absolute accuracy.
How often should I test my monitor?
Test your monitor when you first get it, after any impacts or changes, if you notice display issues, or every few months for professional use. Gaming monitors may benefit from more frequent testing to maintain optimal performance.
What if I find issues with my monitor?
If you detect problems like dead pixels, significant color issues, or poor uniformity, check your warranty status. Many manufacturers have specific policies for pixel defects and may replace the monitor if it meets their criteria.
