I currently have a 6970 and I'm using the DVI-I port to run my main monitor (24" AOC with VGA-DVI adapter think its analogue only?) I have another analogue monitor lying around that I would like to use but I'm aware I cant run it from the DVI-D port.
I'm wondering if I cant use a minidisplayport/hdmi adapter on it? Will that work?
As long as it is an "active" adapter you can go DP -> VGA.
HDMI may not have the analog video you require. Most of the cables I see have this "Note : This cable don't support signal from VCR, COMPUTER or LAPTOP output, only support DVD Player output." and here is the interesting part. "Fully HDCP Compliant to provide the highest level of signal quality" HDCP does NOT work on analog at all and the cable would have to be active to make it "work".
