They all should support it through the VIVO out or whatever port. I was using the component out via the adapter to go from VIVO (or whatever NVIDIA called that connector) to component and S-VIDEO. I haven't tried SVIDEO, but component has been broken since. It worked with my 7600GT, switched it to a Sparkle 8400GS. VGA works fine, no reason to think DVI doesn't, this is just having issues with component out at 480i on my SDTV (again, this previously worked with my 7600GT with older drivers). Can't really revert the drivers on the 8400GS as it requires downgrading kernels and Xorg versions.
