I have a 2011 MBP 13. 

I have been using the Apple min DVI to VGA adapter to mirror the display to a wide screen Samsung for my classes.  That works well.

I would like to do the same with our 42" Panasonic Plasma monitor at home.

So I bought a PNY mini Display to HDMI adapter.

I have an HDMI cable setup for our Apple TV box.  That works very well.

But when I plug this HDMI cable into the mini DVI to Hdmi adapter out of the MBP, nothing happens.  When I go in the Display Prefs, it does not notice that I have plugged an external monitor like it does when I plug in the VGA cable in.  It only show the laptop display with no option to look for another one.


Do I need to do something special for the MBP to recognize the HDMI monitor?  I've tried chanign the resolution as was suggested by another post on this board but that did not make any difference.


If all else fails, I will have to order a VGA cable but that seems a shame since the MBP is supposed to support mini DVI to HDMI.


Thank you for any help.
