Check the listing for details. ProPlex x4 DVI Splitter 4 way 1U Rackmount. Color: Blue, Condition: Open box. Listed at 345.00 USD. Datapath x4 in a 1 RU chassis with built in power supply. The Datapath x4 is a stand alone display wall controller that accepts a standard single or Dual-Link DVI input and can flexibly display this across four output monitors. Each output can be driven as DVI or analog RGB, and can represent an arbitrary crop region of the original input image. The output resolution and frame rate does not need to be related to that of the input as the Datapath x4 will optionally upscale and frame-rate convert each cropped region independently. Additionally, each output can be independently mirrored or rotated through 90°, 180° or 270° to support creative mixes of landscape and portrait monitors. At high resolution, DVI signals cannot normally be guaranteed beyond 5m cables due to the nature of the signal losses inherent in the DVI cables and connectors. Datapath have added active equalization hardware on the x4 which is able to compensate for these losses and support cable lengths of up to 20m even at full Dual-Link resolutions (330Mhz pixel clocks). Lower resolutions will allow even longer cable lengths.
