Trying to decide which way to go on a screen, hoping you guys can help.
I am looking at a BenQ W1070 with a 130" diag screen at a 12'6" throw distance. The room it is in is a 3.5 wall home theater with the half wall being a built in wall/bar that connects to a game room. During the day there is very little light from the left side of the room where the bar is, not enough that you could easily read a book in it, and at night it is almost pitch black to where you can't see your hand in front of your face at full reach. The room has a lighter brown eggshell type paint. light gloss (satin).
Trying to decide how much gain for the screen in this situation. I have read the 1070 is like a light cannon, plenty of power at this distance, and I don't want to go too high (1.5+) on a screen and end up with it being too tough to watch. At the same time I am worried about the bit of ambient light and paint.
Thinking around 1.3 to balance the room with the projector.
Projector Central with this configuration says Image Brightness of 23fL on a 1.3 gain 16:9 130" screen at 12'6" throw is for a room with ambient light.
OK, I don't have a sig... yet.
