Use the tools with their limits in mind

These free tools are provided for practical checks. Results depend on your browser, operating system, settings and connected equipment. No result guarantees hardware condition, resale value, fitness for a particular use or successful repair.

Keep sound volume low and avoid prolonged listening to test tones. Display tests use static patterns without flashing. Stop if a test is uncomfortable. Do not enter passwords or personal information into any test area.
