The secondary monitor is connected to the on-board MOBO GPU, and is detected in device manager, but only showing a black screen.

Ivy Bridge 22nm Technology
RAM

Motherboard

SONY TV (1280x768@59Hz)
Intel HD Graphics 4000 (ASRock) This is what isn't displaying
3072MB ATI AMD Radeon HD 7900 Series (Gigabyte)

You cannot use the on-board GPU with a dedicated card at the same time. The only way to use multiple GPU's that I'm aware of is in SLI or Crossfire configuration.

That is incorrect you can run multiple monitors off different gpus so you can use onboard with amd or nvidia or even nvidia with amd. The monitors will use whichever gpu they are connected to for processing power.

Also to clarify, I had this set up working, then after some cleaning it stopped working. I checked to make sure things weren't unplugged however. I'll try a few of these suggestions.
