2 GPU's, only showing 1 device

So I just got another card.  I've never used two cards, so I didn't know how to install the right drivers, so...

I reformatted.  Got a 100% fresh install.

MSI is showing readings for the two, but I can't get a miner to recognize the other one.  I had read that people need dummy plugs, but I thought that was only for 6x series.

I may be missing something very obvious, but if someone could point me in the right direction I'd appreciate it.

(Win7x64, SDK 2.4 Cata 11.6, 2x 5770)

No dummy plugs are required for drivers 11.6 and below regardless of the card you may wish to try this method

In addition if you installed a crossfire bridge remove it

Okay, I had to plug another monitor in and reboot.

Edit: Thanks for your help!
