Currently i am using GT1080Darbee from Optoma on a 135" white projector screen (fixed type). It has a throw ratio of "Throw Ratio: 0.50, f/2.8 "

The room is always dark.. no issues in that.

But i find the contrast ratio is very bad. Blacks are like in worst state.

I found that using grey screen would help.

a) Can i paint directly on a white screen (as i cannot use wall because of sockets , switches running in wall)
b) Grey mix formula (available in india) which I could use here.

The issue with grey walls and grey screens is they will also tilt your color balance. Say a pure white will not be white anymore. Does your projector have an auto iris setting - if so what is the value you have set? How old is your bulb? If you projector has presets have you tried the movie option?
