no... for my setup is lens to screen ard 7呎5" and i am using grandview電幕...
actually i want to buy fix screen.. so the throw distance can be longer.. but my boss dont let me move away the LCD TV..
ching... you better go out to have a look... ask the shop to simulate the setup for you
and you can see the result is ok for you or not... that's what I do b4...
i think OS or 菊池 is better... but nearly double price compare to grandview and if your room is dark enough should be ok...
mine one is 70" cost ard 4k last yr...
sorry.. cant pm you
