Totevision LED-803HD2

The LED-803HD2 stacks two 8-inch LED-backlit screens into a 4RU rack panel, giving a rack two independent views without giving up much height. Each 800 x 600 panel is 4:3 native and accepts signals up to 1080p, running 250 cd/m2 against a 500:1 contrast ratio behind an anti-glare coating that keeps rack lighting off the picture. The always-on behavior matters more than it sounds: apply power and the monitors come up, which is what you want in an unattended rack that may be power-cycled remotely and has nobody standing there to press a button.

Each monitor takes two HDMI inputs and a composite BNC input with a BNC output, and an RS-232 input on 3.5mm lets a control system drive the panel. Audio comes in on RCA or a 3.5mm PC input and plays through two 1.5-watt speakers, and an IR remote handles setup. Two 2.1mm DC jacks feed the panel from 11.5 to 13 VDC at 1.2A, drawing 20 watts maximum. The durable metal case fills 4RU and weighs 6.1 pounds net.
