Enjoy bright, clear images in your classroom with the NEC NP-MC453X 4500-Lumen XGA Education LCD Projector. Its 4500 lumens of brightness can overcome ambient light in most classroom settings, while its 16,000:1 dynamic contrast ratio can help ensure discernible detail in most images. The projector's native XGA 1024 x 768 resolution is suitable for most video and file formats, and will accept up to 1920 x 1200 resolution source inputs. The NP-MC453X has VGA, composite video, and two HDMI inputs to support most input types, plus an analog audio input and built-in 16W speaker that will provide audio for your video. The 1.5 to 1.8:1:1 throw ratio and 1.2x zoom allow you to place the projector near the back of the room in most cases. It is controllable via Ethernet, RS-232, the included IR remote control, or various control software options.
