Contact Us

Have a question about a display defect, a bug in one of our tools, or a correction to a wiki article? Send us a note and include enough detail for us to understand what you tested.

We read support messages and corrections manually. We cannot provide warranty decisions for manufacturers, but we can point you to the right test pattern or article when possible.

Technical Support

For technical questions, bug reports, privacy requests, or content corrections, email:

For display issues, include the monitor model, panel type if known, browser, operating system, the test page you used, and a photo if it helps explain the issue.
