Dispcal -v -yc -R is consistently giving white level reading as 2xxx cd/m², which seems to be incorrect or am I misunderstanding something? Using Spyder3 and measuring Sony G420 CRT. Dispcal version is 1.1.0RC2 but the win32-usb is what came with an early 1.1.0 beta because I already have it. Datacolor software reading is 144 cd/m². BR, -- Vallo Kallaste
