I plan to run 3 monitors. My idea was to run a pair off the mobo using on board graphics and run the primary off the dedicated GPU.
However, right now when I have the graphics card in the mobo and start it up I get no picture anywhere. When I remove the graphics card from the board I get picture but only using the VGA port on the mobo. The computer seems to recognize when I use the DVI port because I see a change on the VGA monitor, but nothing shows up on the DVI monitor.
Edit: I got the mobo to work with both VGA and DVI ports, but if I install the video card nothing works so that issue still remains.
installing a video card disables the onboard graphics. You can try using one of the other pcie slots. I've never tried doing what you want to do so I'm not sure if only the primary slot disables the onboard or not.
