DVD-D to VGA with KVM Switch

I have the IOGear MiniView™ Micro USB PLUS KVM Switch with audio and cables (GCS632U) http://us.iogear.com/product/GCS632U/ .

I have a new Nvidia Geforce GTX 670 and want to do dual monitors (both VGA). There is one DVI port on the card, which allows you to put a DVI to VGA adapter on it to go to a VGA monitor. The other port is DVI-D and only allows a DVI cable connection to DVI enabled monitor.

I know that you cannot get a DVI-D to VGA adapter http://www.amazon.com/Male-DVI-D-Female-VGA-Adapter/dp/B007EA48MA and put it on a DVD-D port and then go to a VGA monitor, but can you do the same and go to this VGA KVM switch (GCS632U) I have and  then the KVM to the VGA monitor and have it work?

Please no guessing. Thanks.

The KVM is nothing special, it's just a switching device. If you would normally be plugging the VGA signal cable into a monitor and get a picture, it will work to plug it into the KVM instead. Similarly, if it would not normally work connecting directly to a VGA monitor, then it will not work to connect it to the KVM.

As you probably know, DVI->VGA adapters like the one you linked to on Amazon don't actually convert or transform anything. All they do is take advantage of the fact that a DVI-I port on a typical graphics card has some extra pins which also provides the VGA signal, for backwards compatibility. It does a form-factor conversion only. If you only have a DVI-D port you don't have those analog pins, and therefore there's no analog signal for you to use.

This all assumes that your description of your graphics card is accurate - you said one DVI-I port, and one DVI-D port. Personally, that seems a bit strange to me, all my graphics cards have had two DVI-I ports.

You can tell if you have DVI-I ports on your graphics card by looking for the additional four analog pins on connector. It is Pins C1, C2, C3, and C4 in the pinout diagram on this wikipedia page: http://en.wikipedia.org/wiki/Digital_Visual_Interface

Huh. Well I'll be darned it only has one DVI-I port.

Looks like it's time for at least one new monitor, my friend.

Thanks Frosty555. That was an excellent answer. Issue is that I am using all of this with a KVM  Switch that is VGA between 2 computers. Already have DVI compatible monitors. Need to get new DVI-D KVM switch. Single-Link will be fine.
