I am planning to buy Optoma HD25 for my room which is 9x9 ft. So just wanted to know whether this projector will be suitable for this room or a larger room is required for 3d/HD projectors. I will be installing Yamaha YHT299 speaker system and Sony playstation for playing games. And some times will be using it to play 3D movies as well. So for this requirement whether i should buy OPTOMA HD25 projector or a Passive 3d LED Tv. I am confused please help.
