Hangten Posted June 6, 2010 Share Posted June 6, 2010 Its simple your card is not fully supported! I have installed on a friends computer an HD4670 and only VGA out fully working. The mobile version is another story and thats whats used on some iMac. So, to cut the story short there are methods posted on getting your card partially working but as of yet I have not encountered a fully working method for the flavors of various HD46xx series cards. To get full support an HD48XX with the dual DVI seems to work for most people. I can confirm that all is working on my particular HD4850. HDMI, VGA, DVI&DVI, VGA adapter & VGA adapter. However you can't run HDMI and VGA or DVI in a mixed bag dual monitor. This mixed bag is true of OSX and Windows 7. HDMI seems to run solo and I believe its because of the embedded digital audio.
