Hi,

I'm trying to connect 3 monitors to my Sapphire HD 7770 OC edition which has 2 mini DP ports,1 HDMI and 1 DVI port. So I have 2 adapters mini DP to DVI (the 10$ ones from amazon) and I have a Sapphire HDMI to DVI adapter(maybe I could use that in some combination). So I connect 2 monitors via DVI cables into the DP adapters, and one monitor into the DVI output of the card via VGA cable with a VGA/DVI adapter. And I cannot duplicate the 3rd monitor in catalyst. So it recognize 3 monitors but I cannot duplicate the 3rd, only 2 monitors are working in the same time and I can chose which ones...So should I get a new monitor with a DVI output, or buy new active adapters becouse I think the ones I have aren't active. In this case can I buy just one or do I have to buy 2 ? Or can I buy 1 active DP and then use the HDMI to DVI adapter ? I hope someone can help me.

Sounds right. Only hang up might be with your DVI port. If it's a DVI-D then the adapter won't work. If its a DVI-I then you'll be fine.

It's my understanding Eyefinity requires identical monitors with identical settings to work. Is the case with you?

So I have to get one active mDP to DVI and then it should work like this:

Monitor 1 : hdmi to DVI adapter with a DVI cable
Monitor 2 : that mDP to DVI that I will buy with a DVI cable
Monitor 3 : the DVI output on my card with a VGA cable and a VGA/DVI adapter

And that will work ?

Thank you again.
