About NEC NP-P451W

Give your presentations a boost in brightness with the NEC NP-P451W, a widescreen entry-level professional installation projector loaded with eco-friendly and advanced technologies. Ideal for corporate boardrooms, higher education classrooms and government training rooms, this model delivers remarkable brightness (4500 lumens) and features built-in wall color correction, wired and optional wireless networking, closed captioning and up to 6000 hours of lamp life (in ECO Mode). The NP-P451W touts an active lens cover, which hides content, mute's audio and lowers lamp brightness to 25%, allowing you to maximize the effectiveness of your presentations.

NEC NP-P451W Features

  • Dual HDMI inputs with HDCP ensure quick switching between presentations and they also allow for simultaneous digital connections of HD sources including Blu-ray players, cable boxes, satellite receivers and computers
  • The Carbon Savings Meter calculates the positive effects of operating the projector in Eco-mode, which is encouraged by an optional message at startup. A green Eco-mode button on the remote control makes the switch easy

  • Variable audio-out allows you to adjust the volume of an external speaker system using the projector's remote control
  • 4000:1 contrast ratio ensures detailed images from all inputs
  • Four audio inputs make it easier to add sound and enhance your presentations
  • 16W mono speaker provides enough volume for large rooms
  • Built-in cornerstone correction including Pincushion and Barrel correction
  • Eco-mode extends lamp life, lowers audible noise and reduces total cost of ownership
  • The projector's 6000-hour filter reduces cleaning frequency for a lower total cost of ownership
