Using the tools
ScreenBlack tools are provided for general informational and practical use. You may use the tools for personal, educational and ordinary display-testing purposes.
No guarantee of diagnosis
Browser-based visual tests can help you notice possible display issues, but they do not provide a professional hardware diagnosis or guarantee that a display is defective. Manufacturer specifications, warranty terms and professional testing should be used for important purchasing or repair decisions.
Availability
We aim to keep the tools available and functional, but we cannot guarantee uninterrupted access or that every browser and device will behave identically.
Changes
Tools, content and these terms may be changed as the site develops.
