Could someone very familiar with VE explain the PLUGE/black level setting- the one with the 2 bars against a grey background? I tried this yesterday, and if what I understood is correct, my brightness level was at an insane level of 60. If my eyes don't deceive me, when I watch a movie, a 'normal' brightness level seems to be about 30-35. 60 is WAY too bright. Should this be done in total darkness, etc.? Any input appreciated. I know I must be misinterpreting what is supposed to be done. Thanks.
