Photoshop: Not detecting GPU (multiple cards)

I've recently got a second monitor and I had no other choice but to hook it up to the onboard Intel HD graphics. The primary monitor (and also the one in which I want to use Photoshop) is plugged in my Radeon HD 6670. When I launched Photoshop today, it told me that there's a problem with detecting the GPU and I should get the latest drivers (which I do) or contact the maker (which I don't want to do). Tried doing this, but to no avail. Hope someone can help me.

Is there an option to plug both monitors into the HD 6670? That would likely get PS to play nice with your GPU.

Nope, I'd have done that if it was possible already. Both of my monitors have VGA plugs, while the dedicated graphics card only has one VGA, DVI-D and HDMI.

Did the video card come with a DVI > VGA adapter? Try that if you have access to one. If you can get both monitors connected to that card everything should work as expected in PS.

Nope, impossible to get one as well, since the card has DVI-D, which doesn't carry analog signal (VGA is analog).

Guess there isn't a solution?
