Distribute one VGA signal to four VGA monitors, Gefen EXT-VGA-145


One VGA Input, Two VGA Outputs

The 1:2 VGA Hub allows computers with VGA graphic cards to be connected to one or two VGA compatible monitors or projectors. The VGA splitter keeps your desk clutter-free, relocating your computer to a safe and secure area, while allowing you to work in a quieter environment. It also lets you keep your VGA next to your computer, while adding a second VGA display such as a projector, another VGA monitor or Plasma display.


One VGA Input, Four VGA Outputs

The 1:4 VGA Hub allows a single VGA input to be simultaneously displayed on up to four displays. This product is an excellent solution for presentations, digital signage or any application where a single VGA image needs to be shown on multiple displays at the same time.

How It Works

Simply connect the VGA video source to the 1:4 VGA Hub's input using the included cable. Up to four VGA displays are connected to the Hub's four VGA outputs. VGA output 1 is the primary connection and is used for the main display. Outputs 2, 3 and 4 will mirror the primary connection.
