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

I would check ebay. There is a lot of cheap adapters there.

Just make sure you choose the correct port and sex.

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.

checking ebay would be the way to go...

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.

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.

Thanks guys, appreciate the quick reponse.
yes...I had dual screens set up this way...
