Il y a un post intéressant sur AVS sur le réglage des G70.
Ainsi que la procédure du réglage des G2
As for the G2 settings, set the Contrast at 80 and Brightness at 50 and put the Bias & Gain at the basic settings listed in the SM for 6500. Turn off the ABG and go into the G2 settings and select the "pluge" pattern (there are only 3 patterns you can select in the G2 mode) and raise or lower each G2 setting until you can just see the brightest bar of the pattern on the screen. The room should be completely dark and you should turn off the colors not being adjusted.
