DVI-I ???

Hi, got a new graphics card yesterday and there are two DVI connectors, one says DVI-D the other is DVI-I. Can anyone through any light on the DVI-I connector as I havn't seen this before and not sure which connector to use.
Thanks.

The DVI-I contains both analogue and digital connections so you'd use that one if you want to connect one of those little DVI to VGA converters so you could plug it into a VGA output.

The DVI-I give you the option to use a DVI to VGA adapter to hook up older monitors.

DVI-I will also drive standard DVI-D monitors (or HDMI monitors with a cheap adapter) just as well as a DVI-D port.

If your monitor's resolution has a 60Hz refresh rate, DVI-D input and 1920x1200 or less resolution, then I would personally use the DVI-D connection. As most cards that have this DVI arrangement (like the recent AMD cards) have the DVI-D as only single link, while the DVI-I is dual-link (higher bandwidth). Therefore, if your first monitor can be run on the single-link connection, then this leaves the higher bandwidth and more versatile dual link DVI-I connection free to use with future monitors (which could be 2560x1440+ res or 120Hz refresh rate).

Ok, my monitor's res is 1920 x 1080 with a refresh rate of 120hz. I use it for 3D gaming, so which would be the best port to use? My connecting cable is DVI-D.

For 120Hz you need to use dual link DVI or DisplayPort.

The DVI-D will only be single link (I assume an AMD card) so you need to use a dual link DVI cable with the DVI-I connector which will also be dual link.

Your 120Hz monitor probably came supplied with a dual link DVI cable.

I upgraded from GTX580 TO GTX680 i do use a DVI-D cable which came with my benq 2410t 120Hz monitor. My 580 had two DVI-D connectors but this new one has a DVI-I as well as a DVI-D port. I have at the moment got it connected to the DVI-D port. Would there be any benefit if I changed it over to the DVI-I port or should I just leave it as it is?

If i'm reading right, it would appear that 120Hz monitor would be better in the DVI-I port using the dual link cable, is this correct?
Thanks.

The GTX 580 and GTX 680 both have two dual-link DVI connectors.

As far as I'm aware neither connector on either card is single link DVI-D.

You should get 120Hz/3D from either connector using the correct cable and an NVIDIA 3D Vision Kit for 3D.

Yep, I do get 3D with the connection i've made so i'll just leave it at that then. Thankyou.
