"They weren't lying when they said Optima's BigVizion was big. Man, a 100-inch the display is simply huge! It is powered by a 1080p front projection system (kind of) that is installed behind the display and then projected up onto a mirror and then onto the screen. The whole system allows for a very large, and high-quality, picture without  the pain and agony that traditional front-projections can cause. This type of system can cost above the MSRP $19,999 once installation is involved and keep in mind, this system is installed in you wall so there needs to be at least 30-inches available.
