Screen Tests Are a Guide, Not a Diagnosis
Our screen tests, such as the white screen, dead pixel test, backlight bleed test and refresh rate test, help you spot common display problems. Results can be affected by your browser, graphics settings, display settings, room lighting and the device itself. A test result is not a professional diagnosis, and it is not proof of a defect for a warranty or legal claim. For a confirmed diagnosis, contact the manufacturer, the seller or a qualified repair technician.
Repair and Troubleshooting Guides
Our guides explain general steps that are commonly used to troubleshoot screens. Following any step is at your own risk. Some actions, such as applying pressure to a panel, opening a device or changing hardware settings, can cause damage or void your warranty. Always check your device manual and warranty terms first, and stop if you are unsure.
Health and Safety
- Bright full-screen colors can cause eye strain. Take regular breaks and lower the brightness if your eyes feel tired.
- Some tools show flashing or rapidly changing colors, such as the stuck pixel fixer. Do not use these tools if you have photosensitive epilepsy or are sensitive to flashing light.
- Leaving a static image on an OLED screen at high brightness for a long time can contribute to burn-in. Use full-screen tests for short periods.
