I finished a big piece of the theater room today. The electric projection screen is hanging. I could not hang it any sooner because I needed to make sure the TV on the wall would not get in the way. I took a chance and ordered 6″ brackets made for a different screen (although suppose to work with mine) and hoped that the screen would have enough clearance. It has alittle less than 1″ between the TV when the screen goes down. The TV was mounted with a low profile mount, so it only sticks out about 5″ or so. I have also included a video 
Its about 1 and a half minutes and shows the screen operation. The screen will look a little dim until the projector warms up.
The plan is to wire the basement for 7.1 Surround Sound, 2 wall mounted Tvs, a 1080p HD Projector and an electric drop down projector screen. I hope we can finish on Saturday so I can go home. I have not been home since last Saturday at 4am! I am in Newark for a training class until friday.
