How to Buy

Overview

The PT-LW271U is a lightweight and portable projector with WXGA (1,280 x 800 pixels) resolution that delivers 2,700 lumens of brightness and a 4,000:1 contrast ratio. In addition to a 10,000 hour maximum lamp replacement cycle, its Intelligent Lamp Control System automatically adjusts the lamp output in accordance with the brightness of the projected image, effectively reducing power consumption of the unit by up to 70%. The compact, ultra-light unit is convenient when moving between locations, measuring 11-11/32" x 3-15/16" x 9-3/32" and weighing just over five pounds. The ecological design of the PT-LW271U greatly reduces any environmental impact, with power consumption a mere 0.5W in Eco Standby Mode.

Ease of operation and installation are facilitated by several advanced functions, including an abundance of interfaces including an HDMI input terminal, 2 sets of computer (RGB) input terminals, a wired LAN terminal, and a serial (RS-232C) terminal for external control. These features support a wide range of system architectures for portable or ceiling-mounted use. The projector's "Wall Color Setting" mode corrects the color schemes of the projected image when projecting on non-white surfaces to prevent color irregularities.

The wired LAN terminal allows Crestron's application software, "Crestron Connected™", which can control various system devised by using a personal computer connected to the network.

For simplified maintenance, the projector incorporates top-panel lamp replacement, which means it does not have to be removed from a ceiling mount for upkeep.
