I've got a 13 x 11 bedroom with white walls. When I close the blinds (I have a blackout blind) very minimal light comes into the room. I have a Mitsubishi HC3800 and am projecting about an 100" - 110" image onto my white wall. I have decided it's time I buy a projector screen now that I've got some more money to spare. I am just wondering as I've seen many different types of projector screens. These are: Grey, White, and Glass Beads. And all this other stuff about gain. I am clueless to what any of this means so I'd like a bit of help from the people at avforums? Which one should I be looking to get? I have about.. a £150 budget. I'm not really fussed whether it's pull down, motorised or fixed to be honest. I just want the best picture quality I can get for my £150, and which 'colour' I should get it? (Grey, White, Or Beads?) Thanks.
