I live in Australia and i am having trouble finding a active mini DP to DVI adapter. I did buy one from PCCG, the Wicked Wire one, but it... Sucks. Its always stuck on 640x480 res and even if i pull out the USB cable the display does not change, so this means its either NOT active and the USB is just for show or its totally screwed.
So i am going to return the Wicked Wire adapter tomorrow and was wondering if you guys can recommend a Active Mini DP to DVI adapter that i can buy in Australia. Preferably from a trusted Aussie store. I would like to keep buying internationally to a minimum.

I recommend you stick to adapters on the Eyefinity Certified Dongles list (on AMD's website), or, any knowledgeable staff member at a reseller, because, we constantly get phone calls from people who have purchased from eBay, with exactly the same issue.
Part of the problem is:
1) At least one of the initial major manufacturers of DP Passive Adapters wrote "Active Technology" in their description of the product accidentally (and it persisted for a few long time).
2) The first few links on Google for a very long time described an Active adapter as one which was simply externally-USB powered. Many resellers started marking any adapter with an additional USB power connection, as active (which was incorrect). The difference between Active and passive adapters, is that the Active adapters have a special converter chip to modify DP signals specifically into DVI/whatever, whereas, the Passive adapters rely on the video card to do the conversion (but, Eyefinity cards at least can only do so for 2 ports max).
I strongly recommend Accell (Accell is the retail arm of Bizlink actually), however, I'm heavily biased towards Accell, because we distribute them in Australia. Accell is also the first manufacturer I am aware of which is producing active HDMI adapters so far.
