Will any mini display port to HDMI cable work with my7970? Like the mac ones?

Nope. While the Mac's DP port can also output digital and analog signals, the one on the 7970 can't. You will need an active adapter. Alternatively, use a DVI to HDMI adapter instead.

How about the OcUK ones?

That's just turning the mini DP to DP. You want HDMI right (You mention mini DP to HDMI in your first post)?

Excuse my ignorance but they seem the same. I was looking at the quickest method to link a mini dp to my monitor via HDMI.

Well DP and HDMI are two completely different things, both physical and signal . On the Mac the DP on that can do HDMI signals, but the one on the 7970 can't, hence why you need an active adapter to convert the DP signals to HDMI. A passive adapter that only rearranges the pins hence won't work as it does nothing to the signals.

Does your card not have a HDMI or DVI port? And if this is for a third monitor, what connections does it have? You can get active mini DP to DVI for far cheaper.

I'd found some cheap ones on the bay as I was looking to spend as little as possible. The 7970 I have has got 3 mini DP ports, 1 HDMI & 1 DVI-D. The DVi-D will be used by the secondary monitor, as it doesn't support HDMI, and the primary will be the HDMI connection.

The enquiry It was purely to keep costs down, but if I was to use mini DP, that is obviously not going to happen. I'd not had time to read it up in all honesty, was all a little rushed.
