DisplayPort?

I have an extra monitor to connect to my PC but all my DVI ports are used up. I have HDMI and a "DisplayPort" on my graphics card... but my monitor doesn't have a DisplayPort input on it. It's got VGA and DVI. Anybody know how I can set it up? I don't know about DisplayPort/Mini-DP or anything other than the names - is it a DisplayPort on the ATI cards? is there some converter or cable I need like the old VGA-DVI ones that used to kick around before DVI became commonplace?

Thanks

The HDMI port on your graphics card sends same signal as DVI, get a dvi cable and a DVI to HDMI adaptor. Display port is a different signal, so doesnt work with DVI without an active converter, Display port could be converted into VGA cheaply, but HDMI/DVI conversion makes sense.

Ah, Ok. I'll do that, thanks!
