The NEC SB-L008WU is an add-on accessory module for use with NEC MultiSync 20 and M series large screen displays. With 1 DVI input and 1 DVI output, this module allows the DVI signal received by the monitor to continue on (loop-through) to a second monitor. When installed in multiple monitors, this module will allow up to 9 displays to receive the same DVI signal from a single DVI source. This eliminates the need for an external DVI splitter, amplifier and power supply along with the cost, hassle and tangled wiring associated with that distribution method.
Consequently, this module is a must for video banners ribbons and walls in addition to back-to-back installations in environments such as transportation, public information and digital signage networks.
