George Washington University's School of Business Presents the Latest Video Wall Technology

The George Washington University enhanced its School of Business with a new state-of-the-art audio visual system. The plan was to create an impressive showpiece in the facility's atrium lobby. Supported by GWU Associate Craig Linebaugh and the Academic Technologies Department's Assistance Vice President, PB Garrett, Robert Hines, Manager for AT Support Services explained, "The Business School atrium is a collaborative environment, a common area for students as well as the passing public. The university wanted a high impact display system that would engage students and passersby in the University venue."

The George Washington University School of Business showpiece lobby captivates students and public viewers with its two multi-screen video walls powered by RGB Spectrum's MediaWall® processors.

To devise a captivating display system, the University enlisted the services of audio/video technology integration specialists, The Whitlock Group, in Alexandria, Virginia. According to Randy Stewart, Director of Engineering for The Whitlock Group, "The objective was to create a versatile display medium that could present an extensive variety of live and pre-recorded video as well as computer-generated visuals. The design team conceived of two video walls comprised of 2 x 2 displays. RGB Spectrum's MediaWall controller was selected as the video wall processor. The MediaWall was an easy choice. It delivers the full capability and real time performance the project required at a lower cost than other systems."

Content on the two video walls is dynamic and varied, designed to be informative and entertaining. Viewers can watch television news, sporting events, financial information, closed circuit university broadcasts, pre-recorded videos, and information on University curriculum, events, activities, and programs.

The MediaWall processors support up to six video and six computer sources. Video sources include high definition and standard video over-the-air television broadcasts, HD DVD players, and VCRs. Computer inputs include PowerPoint presentations, digital signage, and video teleconferencing.

Each MediaWall controller merges the visuals and outputs them to four Clarity Margay 50-inch rear-projection displays at their native 1280 x 720 pixel resolution. Up to twelve separate images can be displayed on each video wall simultaneously. Any image can also be displayed across the entire wall.

Operators use an AMX touch screen controller to remotely select content for viewing and display configurations. The MediaWall provides limitless display alternatives, giving operators complete flexibility to create any arrangement desired. Pre-programmed display arrangements can be implemented at the touch of a button. The MediaWall processors allow operators to choose image sources, resize, move, zoom, and pan images with click and drag simplicity. Features include custom borders, window titling, on-screen digital clock, and colored and shaded backgrounds.

Stewart concluded, "The MediaWall system operates 24/7. It is a rock solid, reliable product. Its combination of exceptional performance, signal versatility, expandability, ease of use, and low price point make MediaWall the best value in the video wall market."

Hines commented, "The MediaWall system is indeed impressive. The system has received rave reviews from visitors and students. Image quality is superb."

Casio LampFree Projectors

Casio LampFree™ Projectors use a Hybrid Laser/Led Light Source that lasts up to 20,000 Hours,Giving You Crisp Clear Images and Rich Colors for years of maintenance free operation.

Up until now, any projector brighter than 2000 lumens has required a high pressure mercury lamp. Casio has announced what it says is the world’s first data projectors capable of delivering up to 4000 lumens in a well lit room that tick the green box by doing away with the use of mercury.

The Green Slim projectors light source uses blue light emitted by a blue laser, green light converted from blue laser light using a fluorescent element, and light emitted by a red LED through a DLP chip. The resulting light means a room no longer needs to be darkened for data projection, with Casio stating that the hybrid LED, laser and fluorescent light source improves the purity of color compared to traditional mercury lamps.

Maximum brightness is possible in eight seconds, with no cool down required, and an auto-correct function does away with vertical distortion should the projector be nudged. Energy efficiency is big on the agenda with Casio promoting the life of the lightsource to be approximately 20,000 hours – almost ten times that of conventional Casio projectors
