Hi, just need some info (yes have looked)
My current setup is:
Z77Pro3 with a G1610 Celeron and AMD HD7750
Monitor: Samsing SyncMaster 2333 (VGA + DVI)
MB only has VGA+HDMI, I connect to VGA
HD7750, I connect to DVI
Set iGPU as main card in FW, use it for boot.
OS X uses HD7750
I usually turn power off at wall.
Turn power on at wall, Turn computer on STRAIGHT away, boot with VGA using Clover, black screen.
give it a while till it kicks in HD7750, press VGA/DVI switch on monitor, BINGO, login etc.
If I turn power on at wall and WAIT till monitor goes to SLEEP, then turn computer on.
Black screen, HD7750 doesn't kick in till same as above, no need to use manual switch!
No major drama, but anyway to switch with software??
I use Macmini SMBIOS, IF I set HD7750 as primary in FW computer reboots.
DOH!! Macmini don't have HD7750
Don't want to change SMBIOS
Suggestions, help, info appreciated
