The Eiki LC-XT4 is a professional large venue LCD projector designed for mission-critical applications in auditoriums, lecture halls, houses of worship, rental and staging environments, and corporate events. Released in 2006, this heavy-duty installation projector delivers an extraordinary 12,000 ANSI lumens of brightness from its quad-lamp optical engine, ensuring vivid, saturated images even in rooms with significant ambient light. The projector can be operated in four-lamp, two-lamp, or single-lamp modes depending on brightness requirements and lamp life considerations.

At the heart of the LC-XT4 are three 1.8-inch polysilicon active matrix TFT LCD panels, each dedicated to a primary RGB color for accurate and clean color reproduction without convergence errors. The projector features a native XGA resolution of 1024x768 with support for inputs up to 1600x1200, and delivers a contrast ratio ranging from 800:1 to 1300:1 depending on measurement conditions. The 1.3:1 electric zoom and focus lens is standard, with a comprehensive selection of optional motorized and manual lenses available for throw ratios ranging from 0.81:1 fixed wide to 12.61:1 long zoom.

Installation flexibility is a hallmark of the LC-XT4. The motor-driven lens shift function allows the projected image to be moved vertically up to ±40% and horizontally up to ±10% with most lenses, enabling projector placement without strict alignment to screen center. Digital keystone correction provides additional geometric adjustment for challenging installations. The projector accepts a wide range of input signals including DVI-I with HDCP, component video, composite video, S-Video, and multiple RGB/HD inputs. With dimensions of 30.8 x 22.9 x 9.9 inches and a weight of 80.5 pounds, this is a permanent installation product designed for rack mounting or ceiling suspension with appropriate structural support.
