Okay so Im having some difficulties hooking up my Sharp 30" LCD and two of my Hyundai 19" LCD screens to my Sapphire 6970. This is what I have tried:

1. Sharp 30" <----HDMI cable ---> 6970
2. First Hyundai 19" <---VGA cable with DVI adaptor --> 6970
3. Second Hyundai 19" <--- DVI to HDMI cable--> <--HDMI to mini-display port adaptor---> 6970

When I go into CCC, it detects that there are three monitors, but it can only enable two of them at once.

Hope this makes sense. Any help would be much appreciated. Thanks
