The V652 has a larger number of inputs than many other devices of this type. There's one each (from left to right) for component, DisplayPort, HDMI, DVI-D (in and out), VGA and composite. The DVI in and out permits daisy-chaining of units when displays are configured in an array. NEC's V-Series and S-Series displays can operate as tiles in a matrix of as many as 100 (10-x-10) units. A single unit can be designated as the master, from which commands are propagated to others and in the array. Arrays and so-called video walls also can be controlled via included RS-232 or Ethernet ports.
