I know OS X finds all screens, because it switches between them.

The problem is, only two out of three are active at one time.

Any suggestions?

What's the port config on your 670?


I have tried all of them.

2DVI and one HDMI.
2DVI and one DP.
One HDMI, One DP, One DVI.

Still no go, when i connect the screens i see OS X recognises it by the flicker.
And if o reboot, it will activate different two screens every time, but never three screens.

Maybe it's the drivers on ML for GTX670 that are bad?

The DP port if it's to another DP port on your monitor should already be an active connection not needing an active converter. Have you tried an active converter from the DP to like say the DVI or HDMI? Also, when you connect up the one DP port do you get a signal out? You're gonna need a signal out working via DP to get the 3rd monitor working.

I wouldn't necessarily say the drivers are bad but they did come out not too long ago.

OS X supports two displays for each Nvidia graphics card. I found HDMI and DP do not work together on my EVGA GTX 570 HD. However, a DVI2HDMI adapter will provide HDMI and DP with HDMI audio on both.
