Projector Questions

[Erman_94]

Hey guys, I will be incorporating a projector setup in the not-too-distant future and just wanted to gain as much information as possible before purchasing anything. I will use this thread to post my questions so that I don't end up making many different threads. I have received a lot of help thus far from forum members and was hoping to learn more. any help is appreciated.

1) Assuming that lighting is completely controlled (i.e. walls painted black, non-gloss paint, no windows etc.) is a higher gain (whiter) screen always better?

2) I think I get the idea that if i were to purchase a 2:35:1 screen i would use masking panels for 1:85:1/16:9 content to cover the black bars that would appear on the side. But with the 2:35:1 screen (using a CIH setup) what would happen if I watched movies that were 2:4:1? Wouldn't I get black bars on the top and bottom? Or would they be so small that you couldn't see them?

3) Also I see there are lots of 'curved' screens now, what determines what radius you should get for a 'curved' screen? How would you know if you needed one/what are the benefits to a curved screen?

Thank you all very much in advance!
