I'm having problems with connecting my retina MBP with external displays of all kinds. The DisplayPort->VGA adapter has a 1/4 success rate. The HDMI port (via a DVI adapter) does not see my monitor.

These monitors all work with every other laptop (Mac, Windows and Linux), including my old pre-unibody MBP. Worst of all, I cannot depend on this laptop to make presentations, because it's often failed to connect to projectors.

How can I debug these problems? I don't see any obvious way to resolve issues when automatic discovery fails.

Has it ever worked in the past or did you have these problem right out of the gate when getting the machine? If it hasn't worked at all, it's probably a hardware issue. –  Jannemans Mar 19 '13 at 7:36
    
It's worked with some monitors, just not the majority. –  Adam Mar 19 '13 at 17:51
    
But the question stands, is there a way to debug/get error messages/try manually? Or is the automatic system the only way? –  Adam Mar 19 '13 at 17:52
