Never assume ANY Z68/Z77 has a (1) -- much less (2) DisplayPorts. I am not aware of ANY Z68/Z77 with (2) DisplayPorts. Most all monitors have and use a DVI-D Port.
So is it a requirement to have (2) DisplayPorts??
The Z68 Extreme3 Gen3 has ZERO DisplayPorts:
- 1 x D-Sub Port ; aka analog VGA
- 1 x DVI-D Port ; typical 'Digital Visual Interface (DVI) + D = Digital only ; (2) versions single and dual link
- 1 x HDMI Port ; sound + video ; several revisions
DisplayPort - to top it off there (2) versions 'mini' and 'standard' ; nice video - http://www.youtube.com/watch?v=xMVDejZH4kw
Q - What monitor or monitors are you using?
