This of course, measured at 100 IRE luminance level.
I have the following question about fL for LCD TV in a bright room:
I calibrated my Panny projector AE4000 for a light-controlled environment with 14 FL @ 100IRE. Everything is fine, including the overall picture brightness. Then I went ahead to calibrate my Samsung LCD TV. Since I always do my TV viewing with a lot of in-room lighting, I thought 50 fL is probably the target for me to go. However, the before-calibration measurement revealed that ~12 fL @ 100IRE and gamma of 2.11. The fL seems incredibly low but I'm comfortable with that level of brightness (at a viewing distance of 9 ft). So I ignored that "recommendation" of 50 fL and calibrated the set with the resulting gamma of ~2.0 (since the viewing environment is bright) and ~11 fL @ 100IRE. I am comfortable with the overall picture brightness. How to explain the fact that my result is so different from the "recommended fL"?
The calibration environment was totally dark; and the colorimeter (Spyder3)was sit tight on the LCD screen.
