Useful to know

What does this tool establish?

Compare local-dimming settings manually. Viewing angle, optical scatter, eyes and camera exposure can create halos. Bright patterns are SDR unless explicitly stated otherwise.

Does this certify the screen?

No. Browser signals, calculations and visual observations cannot certify physical panel specifications or defects.

Where are my files and inputs processed?

Calculations and observations stay in this tab. Optional observation saving starts off and uses only this device. Turn it off or use Clear observation to remove that saved note. Downloaded reports remain on your device.
