Angry Radeon HD 6770 outputs BIOS but cuts signal afterwards on HDMI

I have a Radeon HD 6770 Video card that has 2 DVI and 1 HDMI output. I have the updated video drivers for my model of card. The card will output fine on both the DVI ports but when I use the HDMI port all I will get is the BIOS and POST info then immediately after the signal will cut off (the monitor defaults to a no signal screen). The motherboard has onboard integrated video but that is currently disabled and there is no why to enable it while the video card is installed (manufacture fail-safe). CCC and Windows recognizes the monitor, showing up as "SHARP HDMI" but refuses to output a signal when I tell it to use it. Any suggestions?
