I have a dual monitor setup on my GTX 460. I'd like to use the integrated graphics combo of my P7H55-PRO + I3 550 to display a 3rd monitor. This won't be used for gaming, just for more work space. Is it possible? The integrated display adapter won't show up in the device manager at all. The monitor is plugged in and powered, and working, but doesn't show up in display settings. OS = Windows 7 64bit RAM = 8GB
