I've been asked to help with the purchase of some equipment for the new student union building. In the middle of the building is an atrium with a wall about 40' high by about 30' wide. In the top of this atrium is a set of windows facing East so it will have a lot of light coming in but direct sunlight is only possible in the early hours.
The students want an "Impressive" video wall installed and they have a substantial budget to actually do it. This video screen will be used for cable TV broadcasts, promotional information of upcoming events, and movie nights. It would ideally be HD quality with a Blue Ray player in the system, but that may be out of price range. How big? Well I'm thinking 16x9 (as in feet) is a starting point. We may go larger if we can afford it.
So what technology makes the most sense to you guys? To me a big screen and something like a 15k monster projector is the most logical. However, they will probably have the thing turned on at least 8 hours a day... so lamps could be chewed up in a hurry. Giant Plasma TV? Several Giant TV's networked together to share a picture? High Res LED? What looks best? What has the highest initial cost? What has the highest long term cost? What has the longest life with daily use?
