A Pair of Big Projectors

Classroom projectors are fine for, well, the classroom, but sometimes a larger device is called for. NEC’s PX750U can blast up to 7,500 lumens onto an auditorium screen for lectures or a movie night fundraiser. It can not only connect via wired and wireless networking, but has inputs that range from HDMI to DisplayPort that conforms to the Open Pluggable Spec, making installation easier. It has an electric zoom, can fill up to a 25-foot screen and is HD-ready at 1,920 by 1,080 resolution. The projector costs $17,650. By contrast, the PA550W is a step down the technological ladder with a resolution of 1,280 by 800 and 5,500-lumens, but makes up for it with a maximum screen size of 41-feet. It has wired LAN, an optional WiFi module for wireless connections and NEC sells five interchangeable lenses that can fit the environment of just about any location. It sells for $3,900.

Yeah it much appropriate to have a bigger projector on classrooms to easily facilitate the whole class.
