DVI cable connection confusion

I'm a bit confused on the flavors of DVI connection.

I have an Eizo CE240W monitor. According to the diagrams I've reviewed, it has a Dual-Link DVI-I input. However, it came with a Single-Link DVI-D cable, which worked fine on my old computer.

I've build a new PC with a GTX 670 video card that has both a DVI-I and a DVI-D port. It works okay if I connect to the DVI-D port but I get a degraded display if I use the DVI-I port.

So, if it works, what's my problem?

I have to buy a new cable because the current one is not long enough for my new setup. Almost all of the ones at the store are Dual-Link DVI-D and they didn't work - didn't even get a display on the monitor. Buying online, I can get whatever I need. Should I try to get another Single-Link DVI-D cable or should I opt for a Dual-Link DVI-I cable?

I just can't crack the code on what's compatible with what. I have a call into Eizo, but they are not known for their service after the sale.

What is the compatibility between the four versions: Single-Link and Dual-Link DVI-I and DVI-D?

whats your resolution for the monitor?
Single link DVI supports resolutions up to 1920x1080 while dual link supports 30" resolution which is 2560x1600 i think

DVI I = Digital Video Interface Integrated meaning it can send DVI D (digital) and DVI A (analog) depending on your needs

also make sure when you have to monitor on to have the display mode set to PC and not TV when tinkering in monitor's settings

Thanks, Alvine.

Resolution is 1920x1200 on a 24-inch monitor. If the ports on the monitor are DVI-I (Dual Link), why does a DVI-D (Single Link) cable work and a DVI-D (Dual Link) cable not work and would a DVI-I (Dual Link) work better?
