ATI Radeon HD 7970. Third monitor with HDMI/onboard graphic card?

[JohnWarden]

Hello guys,

I'm trying to hook up a third monitor to my pc. I currently have 2 on DVI connected.

I hooked up the third via HDMI and it's detected, but in order to use it I need to disable one.

I also have onboard graphic card. Enabled it in BIOS, but it won't show up in the device manager.

Here is my GPU, CPU, and Mobo link:

Could anyone tell me if I can make this work without buying an active display port adapter?
Thanks in advance.

Did you ever install the Intel HD drivers? Also, I'm not sure how you would be able to use both GPUs.
