What this tool does not do / Limits
This tool tests only the device and browser you are using right now. It does not test, identify or diagnose a remote iMac, and its results are only as accurate as the values your browser reports.
Frequently asked questions
Does this test check a remote iMac?
No. It only reports values from the device and browser you are using right now.
Why might results differ between browsers?
Browsers report screen and device values differently, so the same device can give slightly different results in different browsers.
