Right..i have fooled around with the obvious stuff..contrast,tint etc..there is a advanced settings option which has Blackext.
Input level
W/B High R
W/B HIGH B
W/B LOW R
W/B LOW B
GAMMA
AGC

Now those are greek to me..what gets me is in the owners manual is nothing about them..not much anyway..as far as their effect good or bad..the settings are numbered and can be adjusted back and forth with them currently being set at 0..so i assume i can just set it back at 0 if things dont look right..i didnt want to touch it until i got expert feedback from you guys..my dad always said dont monkey with it if it aint broken!..lol
