infocus 4805, what gain screen?

[statik]

Using an infocus 4805 in a very dark basement room with only one window (blocked with curtains) what gain screen would I want to use.
I can get this room pitch black, even in the middle of the day. Only light would be from lamps, if they are on.
going with a 72x96 dalite screen. what gain should I get?
1.0, 1.2, 1.5., 2.5?

If you have light control, you don't need any more than a unity-gain screen (1.0), but 1.2 or 1.5 would be fine as well, and help if you watch movies with indirect room lights on.

In a pitch black room you can even go with a negative gain screen.
Mine is a perforated Grayhawk (with 0.85 gain) and it makes a small tradeoff in brightness for better contrast and black levels.

But it's actually not a visible loss at normal screen sizes because our eyes will compensate for lower light conditions (Iris opens up) and it will look pretty much the same. 8O

My first projector was a CRT unit with 140 lumens, and it looked fine on a 100" screen in a pitch black room. 8)

ok the projector has been purchased finally. 1.5 gain screen, wanna keep the picture as large as possible without distortion or degrading quality, how far back should I mount this ceiling mount? my research is showing 15-19 feet. what do the experts say? thanx guys!

Using the throw distance calculator:

You should figure the distance range, depending on your screen size and projector's zoom cpabilities, and put it right in the middle of that range. :T

thanx, already knew about that calc and a few others, didnt know if they were so accurate, I will go with what it says.
now, any recommendations on a fairly priced DVD player to go with the 4805...?
