The Sony VPLCW255 4,500 Lumens LCD Projector offers superior WXGA 16:10 widescreen resolution and environmentally-friendly features. The VPL-CW255 incorporates Sony's BrightEra 3LCD inorganic panel technology that delivers higher picture quality, substantially brighter images, higher efficiency, better contrast, consistent color stability and longer durability and usability. It also features three brightness modes to suit individual user's needs - 4,500, 3,400 and 2,500 lumens. The low brightness mode generates lower operating costs by reducing power consumption and extending the lamp lifetime to approximately 5,000 hours. The projector also has a contrast ratio of 3700:1, a range of video inputs, including HDMI and RJ45 or RS-232C connectors for control.
