Title: ATi DVI to Component Video Adapter question
Post by: Veinman on September 10, 2005, 07:33:40 pm
I am currently using the ATi DVI to component video adapter successfully in my cab with a Radeon 9800 Pro.

However, I'm going to be switching out the computer that the cabinet uses, and the computer that's going in is using a GeForce4. Will the GeForce work with the ATi adapter? I was hoping that it was simply a DVI to component adapter and that there was really nothing "ATi" about it.

DVI is pure digital.  Some DVI plugs also carry extra analogue data via some extra pins on the plug.

Scroll to the bottom of that page and look at the difference between DVI-D (pure digital - 24 pin) and DVI-I (digital and analogue - 29 pin).

If your plug is DVI-I, then it will suit most modern video cards with a DVI connector.  Notable exceptions are some of the early Dell Radeon cards that used a larger connector and split the dual-head connections via a cable.  Of course, the end of the splitter cable is standard DVI, and as long as you still have that cable then all is well. :)

I found out much to my dismay that Nvidia cards DO NOT work with ATi dongles. I ended up buying a Radeon 9550 256MB for the PC, cost me $54.50 shipped. :-\

In that case, the DVI->Component adaptor was not a generic unit, but specific to ATi (ie: the RGB->YUV conversion is being done by the video card and not by the adaptor).
