Q: I have problem with dual monitors

I have power mac mid 2012 with ATI Radeon HD 5770 1024MB.

When I turn my computer, both of my monitors (Dell) work great, but when goes into sleep and try turn back on, only one computer monitor works and the other one is just pitch black. When I restart the computer it solves the problem, but I don't want to do that everytime, any ideas why that's happening?

Mac Pro (Mid 2012), OS X Mountain Lion (10.8.5)
