AMD 7950 - how to enable triple monitors? Only 2 are showing. [ML 10.8.3]

[Pr3fix]

Hello,
I have got my hackintosh ML 10.8.3 up and running, it seems to work great except for 1 issue, only 2 out of my 3 monitors are detected by OSX.

The 2 working ones are connected one via DVI, one via mini displayport. The third (non-working) monitor is connected to the card via HDMI.

How can I get the HDMI monitor to work? Is there something in Multibeast that I needed to install that I missed? I had triple monitors working fine until I just updated my multibeast, and now only 2 of the 3 are detected.

Please help!

if u have any adapter from mini dp, be sure is an ACTIVE adapter. without your radeon will work only with 2 monitors.

cheers
