Hi there,
Is the DVI-D connection dual link or only single link? If it is only single link then it won't have enough bandwidth to send the full 2560x1440@60Hz signal to your monitor - so it wouldn't work.
If your DVI-I dual link connection is unused (or underused) then I would suggest switching over to that, since the dual link will happily provide all the bandwidth the monitor requires. Don't worry about the difference between DVI-I and DVI-D, DVI-I just means it includes all the connections for an analogue and digital video connection. If you use a DVI-I connection with a DVI-D cable and monitor then it will connect up fine and look just as good as a native DVI-D connection.

Aye, but it may have all the pins, but still only be single link. For example this HD 6970 has a single link DVI-D port (the upper DVI port in the end-on photo) which looks like it has all the pins, but is in fact only single link (so it couldn't drive a 2560x1440 monitor like yours), when in contrast the identical-looking lower DVI-I port is full dual link and could drive a monitor like yours. May I ask what particular graphics card make and model you are using?
You are definately not missing out on anything when using a DVI-I port instead of a DVI-D port. When used with a DVI-D cable and monitor, the DVI-I port works just like a DVI-D one and the DVI-A (analogue) parts which differentiate it from a normal DVI-D port are effectively bypassed.
You won't need a special DVI-I cable to get the most out of a DVI-I port - a DVI-D cable works just fine. Though obviously you will need a dual-link type DVI cable to support your resolution.
