I have a lot of experience with screens and HT design since we specialize in projector systems, although not as many as in the past with TVs getting larger. We deal with most of the major players Stewart, Da-lite, Screen innovations, Dragonfly, Draper, Da-lite, Seymour/ Screen excellence, I think that is it. Screens are about getting the right one for your application. I'll be happy to give suggestions but there are a ton of questions about your situation that needs to happen.

Some basic questions to narrow the field.
Acoustically Transparent or not?
Ambient light when projector will be used?
Seating distance?
Projector distance?
Room color? More of a media room or dedicated area?
Audio?
Multiple rows of seating?
Movie lover? consider 2.35:1?

And of course, Budget?
