The NP400, NP500, NP600 and NP500W are networked projectors that cost a little under $1500 and include wired networking for remote monitoring of the projector and includes a DVI-I connector. The NP400 is 2500 lumens ($899), the NP500 is 3000 lumens ($1099), and the NP600 is 3500 ($1499). The NP500W is 3000 lumens ($999). All use XGA native resolution – definitely not HD.
These models are mostly for schools and offices, but if you don’t mind the resolution they might make for a good second home projector.
