Hi guys,

Hoping someone will be able to give me a helping hand with the setup of my new KVM switch.

The switch in question is a Rextron DAG12-BK.  It handles DVI video.  Connected to it I have the following:

1. A desktop PC with a DVI video card.  The cable I have between the desktop PC and KVM switch is a DL-DVI-I cable
2. A laptop with a VGA output.  The cable I have between the laptop and the KVM switch is a VGA cable with a DVI-A adaptor at the end which goes into the switch.
3. And finally, a DVI-D cable between the switch and the monitor (a Samsung 22 inch LCD)

Now I get video when the switch is connecting my PC to my Samsung monitor (and keyboard etc).  But when I switch it to my laptop, I only get video on my laptop and not the Samsung monitor.  I've set up dual displays etc, and the laptop can "see" my Samsung (it lists it in the settings).

I'm pretty sure it has something to do with the combination of cables I am using, but I don't really have a clue so if anyone can spot my mistake please let me know.


Cheers.
