DESCRIPTION :

Our Active VGA balun supports a local monitor and a remote monitor via Cat5 or better cabling. Each set includes one transmitter and one receiver.

This solution is really pratical if you want to view on a local monitor a VGA signal and at the same time send the VGA signal to a remote VGA monitor or projector, eg in education or shop displays where the distances involved are greater.

Contrast and brightness adjustment are included for a perfect setup. Both the transmitter and receiver are housed in a robust SPCC with black painting case.

These active VGA baluns work in conjunction with laptops, PCs, flat-screen LCD monitors and multimedia projectors.

All our Baluns are 100% tested for reliability and durability to guarantee your signal integrity
