gigabyte GA--Z68ap-D3 onboard HDMI not recognizing cable

[jeffreyjoy]

Trying to run audio out the HDMI port into home theater AV receiver. i can't select HDMI as an output device in windows as its grayed out. Device mgr says HDMI driver is loaded and working fine but audio comes out regular ports, not HDMI. I believe this to be a device conflict between the two chipset drivers but how do i give the HDMI priority or else disable the regular drivers?
Many thanks in advance !!

graphics card utiltiy under displays should be something dealing with multiple displays.

I can’t figure out how. Radeon catalyst utility only shows one video screen. Would be expected since hdmi is grayed out and thus is disabled. If I were to plug in the cable and enable the port perhaps the utility might recognize that as another “video” and allow me to manage it as well, but of course I cannot see any of that because my monitor shuts down as soon as I enable the port. I would need to put an hdtv or some similar on it to see what was happening, but I don’t have one of those.

🙁 I was afraid that would the the case.
