Large-format Projectors and Screens Technology Showcase
Jan 18, 2011 4:29 PM, by Bennett Liles
Over the past few years the market for large displays has opened dramatically, and the demand has been seen in every applicable display technology. Big displays make a powerful impression, and it appears that when it comes to making that statement, few are content to run in second place. In our survey of large-format projectors and screens, we have chosen to include makes and models appropriate for large boardrooms on up to major performance venues. This wide field is in recognition of the fact that through modern stacking and edge-blending techniques it is possible to use projection units of moderate size and power for more dramatic scale onscreen.
At 10,000 center lumens of DLP imaging, the Barco CLM R10+is a projector aimed at the rental and staging market. With native SXGA resolution, the unit has an all-metal chassis and can be fitted with an optional external frame for easy road handling and sturdy show mounting. Among its other features are soft edge blending, RS-232/422 in and out, and Ethernet remote control. Through plug-in video modules, a wide variety of input video formats can be used, and DMX512 remote control includes true optical dimming for easy integration with show and lighting control systems.
The single-chip DLP PRO7501DP from Boxlight uses dual 280W lamps to produce 7500 lumens at a native resolution of 1024x768 and features +/- 40-degree vertical and +/- 35-degree horizontal keystone correction. Service and network control ports include serial, RJ-45, and a 12V trigger switch. The unit’s inputs include component, RGBHV, HDCP-compatible DVI-D, VGA, composite, and S-Video formats as well as audio on RCA and stereo mini jacks. Imaging uses a four-segment or optional six-segment 65mm color wheel, and the projector is capable of fitting an assortment of lenses.
Capable of being fitted with five optional lenses, the new Canon LV-7590 is an LCD projector with 1024x768 native resolution, automatic gamma adjustment, storable color alterations, and a powered lens-shift mechanism that can adjust the image by 40 percent vertically and 20 percent horizontally. Installation and maintenance features include a center-lens body design, easy-access maintenance cover, side-loading lamp replacement, and an auto-winding filtering system that automatically advances the filter so that it can be used up to 10,000 hours before replacement is needed. The projector accommodates a range of analog and digital video input formats and is HDCP-compliant.
The Christie Roadster HD 10K-M produces 10,000 ANSI lumens in 1920x1080 HD using dual 350W lamps and 3-chip DLP imaging. Designed for maximum performance in a minimum package, the HD 10K-M features standard analog BNC and dual-link DVI video input connections and optional SD/HD SDI and twin HDMI. The unit includes Comprehensive Color Adjustment, embedded Christie Twist Image Warping, and edge blending. It features a motorized yellow notch filter, dynamic iris, multiwindowing, and screen processing along with the Intelligent Lens System for zoom, focus, horizontal, and vertical offset. The unit is a dust-sealed filter-free design.
The Arena Electrol screen from Da-Lite is a retractable model available in sizes up to 19ft. 8in. high by 39ft. 4in. wide. Concealed in a black steel casing is an internal steel structure that supports the roller and fabric assembly and operates the screen by using two steel cables in a built-in balancing system. This assures smooth and even retraction and a flat viewing surface. The steel housing case at the top may be fitted with mounting brackets on the rear or top surface. The screen assembly includes an RF remote control link with a three-position wall switch. The screen is available in matte white and perforated matte white fabric with no borders.
The 3-chip DLP Titan WUXGA 3D projector from Digital Projection includes DP’s FastFrame technology to reduce image blur in rapidly moving content. Designed for simulation, scientific visualization, medical research, commercial cinema, and theme parks, the unit can be ordered with DP’s RapidRig flying and stacking frame for precise 3D alignment. Other features include eight user-selectable inputs with HDPC-compliant DVI and SD/HD-SDI along with ColorMax calibration using seven-point color correction. The Intelligent Lens Mount enables the user to program 10 separate presets for zoom, focus and lens shift. These presets can be assigned and automatically recalled by source and input.
