Well, guess I shoulda looked a little closer. I have amonitor that takes a DVI input and an AT All-In-Wonfer 9600. A quick look at the back of the PC and the connector block ATI supplies made me think I had a DVI connector there, but of course it's a second VGA connector. I had picked up a DVI cable at work and before getting my money back I started thinking about the DVI to VGA cables I saw there. Would there be any real benefit to using that instead of straight VGA? The monitor is a wide screen if that enters into the equation anywhere.

Thanks

One other thing if it makes any difference, the input on the monitor is DVI-D.

Yes it does. The monitor is expecting a digital signal, which a VGA output obviously doesn't provide. No adapting possible.

Sorry Peter, I didn't explain it properly. the monitor has both VGA and DVI-D inputs. I currently have it on the VGA. If I buy a VGA to DVI cable, or converter for the DVI cable I have, I am wondering if anything is gained.

It appears to me that no matter what I am going VGA to digital, just doing the conversion at a different place. I am trying to find out if I get any performance or display improvement by using the DVI input if it actually comes from a VGA output.

Thanks

Like PM said, it doesn't matter because you are sending a VGA signal (analog) to the monitor. you would need the DVI to be at the source (video card), then into the DVI on the monitor.

bottomline, you would need a different video card to take advantage of DVI on your monitor.

Gotcha, it appears the only reason for a conversion cable is to connect devices that have no options. Just might start looking at video cards....

No, the point is that conversion cables just convert plugs, not signals. DVI-to-VGA cables only work in that direction, taking the analog signal from a DVI-I /output/ onto a VGA plug. You cannot magically make the analog VGA signal into a DVI-D /input/ for your monitor.
