1xDVI, 1xHDMI and 1xVGA monitors on a Radeon 5870
I've been around reading probs and solutions with 3 display setups...
I am aware of this

and have read some other stuff.. As I understand, I have to use active adapters across all the MDPs I wanna use. I currently have the ATI Radeon HD 5870 that has 2 MDP and 1 DVI outputs, and wanna plug an HDMI flat screen, a DVI one and a VGA display.
I am not sure about what config of adapters I should buy. I actually have the DVI native one with a DVI to DVI cable and the flat screen with a Moshi Mini DP to HDMI Adapter with Audio Support. I also have a simple Apple MDP to VGA adapter, and of course when I plug them all, the DVI screen turns black. The AMD eyefinity page lists only one bizlink MDP to HDMI adapter which I can't find. On the other hand, in some other apple communicate I can't remember, they say thaty they consider the Apple MDP to VGA adapter as an active adapter. So I wonder if I should try to find a MDP to HDMI active adapter (i've heard of some startech out there), and that will make everything to work, or I should get a DVI to HDMI adapter and an active MDP to DVI one..? Any recommendations on some of them cheaper but good enough of them?
In advance, thank you!
