This DVI stuff is confusing. I found the following site very helpful - www.datapro.net/dvi/html
If you don't have time to check out the site - here are some tips I picked up. Use the flat pin to determine cable ID. A flat pin with four surrounding pins is either DVI-I or DVI-A. A flat pin without surrounding pins is DVI-D (digital only), ergo the "D". DVI-I is an integrated cable which can be used for either analog or digital purposes. DVI-A is obviously analog only.
You may encounter either single or dual link cables. Both DVI-I and DVI-D come in both flavors. Not sure about DVI-A. To dertermine which cable you have check the pin set. A solid 24-pin set (rows of 8) denotes a dual-link cable. Two separated 9-pin sets (rows of 6) denote a single-link. NOTE - to distinguish between a DVI-I and DVI-A, the DVI-I will have a solid 24 pin set, while the DVI-A will have a separated 8-pin and 4-pin set.
From the site: "If you have plugs that are DVI-D, they will accept a DVI-D or DVI-I cable. If you have plugs that are DVI-A, they will accept a DVI-A or DVI-I cable. If you have plugs that are DVI-I, they will accept any type of DVI cable."
Further from the site: "If you have mismatched plugs, such as DVI-D and DVI-I or DVI-A and DVI-I, you may use either a DVI-I cable or the cable that matches the other plug."
Most of you know this already. I post this for those that, like me, sometimes get a little confused about this new connector. Hope it helps. Kirk
