- Calibration can use a bank card, a 100 mm bar, or the screen diagonal; the stated viewing-distance range is 0.3 m to 40 ft.
Field notes
The calibration flow offers three screen-measurement routes: match a bank card, measure a 100 mm bar, or enter the display diagonal. The page gives an example calculation for a 6 m viewing distance and 6/6 acuity, and says mirror rooms should use the full optical path. A free account is needed to save named programs for use across screens.
