Peerless-AV announced recently the launch of a 3×3 Universal Video Wall Cart, the DS-VWC655-3X3. Aimed at the rental and staging markets, but perfectly positioned for portable digital signage applications, the DS-VWC655-3X3 can hold nine flat panel displays measuring 46 to 55 inches. The cart features a covered shelf that effectively hides media devices and upright channels to organize cables. Lockable 5″ casters support up to 1,000 lbs. of flat panel displays and can swivel 360 degrees for maneuverability. The company has included mounting hole patterns up to 400 mm vertically while a unique positioning feature enables simple flush alignment without tools.
