What this tool does not do / Limits
This tool tests the device you are using right now, in this browser. It cannot test a different or remote laptop, and it cannot diagnose hardware faults; it only reports what the browser can see.
Frequently asked questions
Can this test a laptop I am thinking of buying?
No. It only reports on the device you open this page on.
What about dead pixels?
No script can see dead pixels for you. Display a solid colour full-screen and inspect the screen yourself.
