Q4: Where do I plug my monitor in to get the best performance when using AMD Radeon™ Dual Graphics technology?

A4: For best performance, AMD recommends plugging the display into your fastest GPU. This will ensure that even applications that do not take advantage of AMD Radeon™ Dual Graphics will still be able to run on the faster graphics card in your system. We recommend that you plug your monitor into the AMD Radeon™ GPU with the higher model number. If that is your APU, plug into the motherboard, if it is your discrete graphics card, plug into that.

So it seems you should plug the screen into the graphics card but you will still get Crossfire assistance if it's plugged in the motherboard. So you can use a GPU with no video output to help on board graphics.
