The 80PH display wall cube gives high resolution on a large cube, with a native 1400 x 1050 DLP technology. The 80" size (78.7" diagonal) allows very large walls to be built with fewer cubes. The 80PH features the Speed Swap lamp changer: when the operating lamp reaches the end of its life, the lamp changer sets a new lamp in place and running within 10 seconds.
