I tested analog and dmcp works fine. However DVI has no output on monitor with either connector.
What's dmcp? With the analog monitor is the driver able to get an edid from the monitor on both ports? check 'xrandr --verbose' to see if there is an edid. If so, then we've gotten the ddc lines correct and the digital encoder are probably reversed.
