Which DVI cable to buy?? Please help.

I just bought an LG 204WT widescreen LCD that contains a VGA and DVI-D (female) connector. I'm planning on buying a Geforce 8800 gts card that apparently only contains dual DVI (DVI-i dual link) connectors (female). The DVI-i looks the same as the DVI-D connector EXCEPT it contains four pins that surround the flat blade area. Am I correct in that all I need to buy is a male to male DVI-D cable and that I won't be using the four analog pins that surround the flat blade on the geforce card?

Yes, It's called DVI-D Dual.

His TV might not accept DVD-A or DVI-I since it's only DVI-D and may not have holes for the other four pins. and so he needed DVI- D Dual-Link for his 8800 GTS which is capable of all DVI connection Single-Link and Dual-Link.

Edit: I can't post with picture since I don't know how to post with picture here.
