After several years happy Sony hs10 ownership but reading on this site how I was missing out on better blacks wonderful contrast ratios, the upgrade bug hit me. I purchased the sim2 30 (not the H) and duly fitted it to the ceiling, connected it up via component cables to my pioneer amp and powered on. My first impression was that my blacked out room seemed to have a light on. Light poured from the fan / vent (now pointing upwards as attached to the ceiling) straight at the ceiling showing the room with radiance. The wonderful blacks and contrast ratio I was expecting were washed out greys. My wife thought the Sony looked better and my daughter asked why the projector acted like a searchlight. Is there some setting on the sim2 30 to adjust for better contrast or reduce the beam of light from the vent hole or is this a feature that is not mentioned about sim2 projectors?
