Hiya, My cousin received his http://www.overclockers.co.uk/showproduct.php?prodid=GX-148-MS&groupid=701&catid=56&subcat=1673

And he wants to run three screens he has the HDMI, DVI all linked up and there is a minidisplay port for the third monitor. So I thought this - http://www.overclockers.co.uk/showproduct.php?prodid=CB-047-OK&tool=3

would be perfect until I read somewhere that if you want to use a adapter like that for 3 screens you need to have an active one.

Do I need an active mini displayport adapter like this one - http://www.overclockers.co.uk/showproduct.php?prodid=GX-058-HS&groupid=701&catid=1915&subcat=1577
 
Which Mini Display Adapter?

Hi guys,

I'm trying to get a friends 7950 to run on eyefinity, currently I have one monitor connected via HDMI and another by DVI. The last one needs to be connected via mini display port so I thought about purchasing this:

That was until I read the review about eyefinity needing an "active" mini display adapter. I don't understand why that is so could someone help me by telling me which adapter I need for this to work preferably with HDMI to MDSP.

Single link DVI will work with monitors up to 1920x1200 rsolution.

Dual Link DVI has higher bandwidth and will support 2560x1600 monitors or 120Hz 1920x1080 monitors.

Active adapters are powered, passive ones aren't (I think).

With the set up in the first post the adapter needs to be active.
 
Hold on, so if my friend plays at Eyefinity resolution (not sure what that is) then would I need dual link?

*Edit* I ordered the single link as I assumed I only needed to take into account that one monitors resolution. Was I wrong?

He only needs an adapter appropriate to the monitor connected to it, the other monitors are already taken care of by their respective connectors.

I assume all the monitors are the same resolution/refresh rate as that's how they have to run for Eyefinity.

If the third monitor is no more than 1920x1200 resolution at 60Hz he only needs a single link active adapter.
