A very small percentage of individuals may experience epileptic seizures or blackouts when exposed to certain flashing light patterns or rapid chromatic transitions.
Our Stuck Pixel Doctor (60Hz) tool utilizes rapid, high-frequency alternating Red, Green, and Blue subpixel strobe patterns designed to stimulate dormant liquid crystal transistors.If you have an epileptic condition or have had seizures of any kind, DO NOT look directly at the screen while the Stuck Pixel Doctor is operating. If you experience dizziness, altered vision, eye or muscle twitches, involuntary movements, or disorientation while testing, immediately discontinue use and consult a physician.
1. Permitted Use of Diagnostic Tools
OnlineScreenTester.com is provided free of charge for both non-commercial personal evaluations and commercial business assessments. Permitted uses include:
- Inspecting new or used monitors, laptops, smartphones, and tablets for physical defects prior to purchase or during return windows.
- Enterprise IT departments and computer repair shops auditing fleet hardware displays and generating diagnostic inspection certificates.

You agree not to use automated bots, scrapers, or excessive programmatic requests designed to impair the stability, security, or availability of our infrastructure.
2. Technical & Hardware Disclaimers
OnlineScreenTester.com provides software-level visual and sensor diagnostics. While our tools adhere to rigorous display metrology guidelines:
A. Software Diagnostic Limitation
Our tools identify optical, chromatic, and pixel characteristics visible via web browser APIs. Certain deep hardware defects (such as internal motherboard display rail voltage fluctuations or microscopic flex cable delamination) may require physical technician disassembly and multimeter analysis.
B. No Guarantee of Hardware Repair
While our 60Hz Stuck Pixel Doctor has successfully revived dormant subpixel transistors in many panels, we make no representation or warranty that stuck pixels, dead pixels, physical liquid crystal leaks ("ink spots"), or permanent OLED burn-in can be cured via software. Physical impact damage and shattered glass cannot be repaired through digital flashing.
C. Inspection Certificate Informational Nature
Our Display Inspection Report and Health Certificates are generated based on client-side browser benchmarks and manual user defect input. While formatted per ISO 9241-307 guidelines, certificates are provided for informational documentation purposes and do not represent a commercial warranty issued by display manufacturers.
