HD4650 HDMI only
 

I need help. I have OSX 10.6.3. I used a modified kext from the web http://www.insanelymac.com/forum/ind...owtopic=202099. The problem is when the OS turns on my monitor went into sleep mode. I tried a VGA monitor to the VGA port and DVI port and I tried a DVI monitor to the DVI port. I do not have HDMI monitor so I can try but I think my HDMI output is ok, because I hear the sound of axes and I hear the sound of Skype to be on.

Is there a way to run a DVI or VGA output

I also have a HD4650 but have not got it to work yet. Seems like you might have a problem specifying the port or the sync signal is beyond what the monitor can display. Did you try hardcoding the size to 1024X768X24 in the start-up parameter and see if it worked?
