You need at least one display to be connected via a Mini-DP port. You will need an active mini-DP to VGA adaptor.
Good to know.
I'm noticing that most of these active adapters are $20 bucks or more. I'm assuming the safe bet is to get one that AMD lists on its dongle support page.
Something I noticed there was that there were no active Mini-DP -> HDMI adapters listed on that page. Is that because none exist? I have second thoughts about using VGA connectors, so I figured I'd just spend the extra 5 bucks and use HDMI->DVI converters instead, so
Monitor 1: HDMI native
Monitor 2: HDMI adapter connecting to the DVI-D (single) slot
Monitor 3: HDMI->DVI-D (single) adapter connecting to a DVI-D (single)->Mini-DP active adapter connecting to a mini-DP slot.
I'm not sure what the difference is between using the DVI single and the DVI dual slot, since each monitor will only be using 1080p. Thoughts on that?
EDIT: Thought DVI-S meant single link DVI, my bad
