MultiVideo DVI switch is ideal for switching dual, tri, and quad-head computer digital or analog video sources simultaneously to up to 4 remote monitors and 1 keyboard and mouse. Crystal clear video at resolutions up to 2560 x 1600 make this unit a perfect addition to any video environment.

Switching and selection are made easy using the front panel display, hotkey sequences, or serial switching commands on a remote computer via a serial cable. MultiVideo DVI can be connected to an additional identical unit and synchronized to switch video from multiple computers. For example, when a switching command is sent to the master unit, the same switching command is sent to the secondary unit. Therefore, both units are switched to the same CPU port and display the same video on all connected monitors. The KVM, USB peripherals, and audio can all be switched in conjunction to a selected CPU port, or can be switched independently to separate ports.

MultiVideo DVI is produced in 3 models:

  • 1x4 Dual-link Dual DVI-I Video
  • 1x4 Dual-link Tri DVI-I Video
  • 1x4 Dual-link Quad DVI-I Video

All MultiVideo DVI models support USB 2.0 keyboards, mice, and peripherals, and include an option for audio.
