Have a Sony hs10 with a brand new bulb. After using Avia... It has deemed that my contrast level should be at around the 76 area ( on a 1 - 100 ) I previously owned a rear proj. and kept contrast around the 50 area. I know that on rear proj. tv's, high contrast levels are shunned as it can bring the burn in. I know that on an LCD projector that burn in a not too much to worry about... but should my level be that high? I mean I trust AVIA and all, but at that high will it diminish my bulb life sooner? The picture is awwwwwwfully nice.
