Does anybody have a retractable screen in their media room, and if so, have you ever had any problems with it 'blowing around' from the airconditioning? I'm considering my options for a media room which will have two functions: TV viewing, and movie viewing. To do this, I figure I need to either buy an extremely large TV (LCD or plasma), or install a recessed retractable screen and overhead projector (my preferred option). There will be airconditioning in this room. Dimensions: Length: 6.2 meters Width: 4.2 meters The airconditioner is installed on the opposite wall to where the screen will reside. I think it will most likely have an effect on it, by blowing it around a litte, thus causing focus problems and may be even motion sickness. Your thoughts? Thanks for your replys.
