DVI to VGA adapter

Hi,

I have a docking station which has a DVI-D and VGA. I usually use one each for a dual display output.

However I know want to connect this to a dual display VGA KVM switch. Is there any way that I can convert DVI-D to a VGA output with an expensive converter? I'm just looking for a simple adapter. It seems this can only be done with DVI-I.

If not, does anyone know if the VGA port on a Dell docking port can be used with a VGA splitter and support dual screens that way? Or will that only provide the same signal to both screens?

Thanks,
Martin

DVI-D to VGA is not possible, cuz DVI-D does not send analog signals.
Though, DVI-I send both digital and analog, thats why this is working with DVI-I.

VGA splitter only sends the same signal/picture to both screens.

I agree with aerion85, I don't think DVI-D can support analog signals.

silemone, did the VGA splitter provide two different displays?

I found a solution which I think will be the only answer.

The Dell screens have two connections, VGA and DVI. I've connected both up and when switching PC's, we'll just have to switch from DVI to VGA on the screen itself. Bit of an arse though , I always thought DVI was simple! Learn something every day...

aerion85,

Yep, I think that's the best info for other people to read so you can have the points. Dell still have the images wrong though, they've labelled the ports as DVI-I !

Can I connect a DVI cable to VGA?
You can connect a DVI-I or DVI-A directly to VGA using our DVIVGA cables because DVI-I and DVI-A send analog signals. You can not directly connect a DVI-D to a VGA because DVI-D only uses digital signals. In order to connect a DVI-D to VGA you first need to use a DVI Converter to electronically convert digital to analog and analog to digital.

They aren't cheap, around $150, but Matrox makes a box that you plug into your VGA output and splits the video to 2 monitors (or 3 if you buy the triple model). It just presents itself to the PC as a really wide monitor, like instead of 1280x1024 Windows thinks you have a monitor that does 2560x1024.

Bah, I'll have to accept two answers. The Matrox product would do the job too, but I'll get users to press a button on the screen each time instead.
