Good corner brightness. TV tuner built in. Contrast ratio, color saturation and overall image quality not as good as Proxima's. Data and power cord plus remote control weigh an additional 1.4 pounds. One computer data input.
Projector includes a serial connection for mouse control of presentation.
One SO-239 cable TV connector on the 3M's video module. Video module has built-in TV tuner. As mentioned in the Proxima review, the 3M MP7630 uses a different projection lens than its Proxima cousin, the DS2. The 3M projector's lens has less zoom range than the Proxima DS2's lens, as well as less contrast and less brightness. The images the 3M projector produces also were not as sharp and clear as those the Proxima unit produces.
