Connections, Cable Length and Other Video Equipment


  • Make sure the connection to all monitors and all USB connections are secure.
  • The light on the DualHead2Go box will be green if all connections are connected properly.
  • Matrox recommends a Maximum of 6ft of cable to the monitors/projectors that are connected to it. We have been able to successfully test these devices with up to 50 feet of VGA cable. Adding a distribution amplifier between the DualHead2Go and the monitor/projector is recommened for cable lengths longer than 50 feet.
  • The DualHead2Go normally will not recognize a vga over cat5 extender. Adding a distribution amp or edid emulator between the DualHead2Go and the cat5 extender sending unit is recommened.
  • The DualHead2Go may not recognize a switcher or scaler as a monitor. Adding a distribution amp or edid emulator between the DualHead2Go and the switcher or scaler is recommended.
