Just would like to add to the debate that I had the same experience using a macbook pro retina 15 bought like 5 weeks ago and I was trying to
connect it to my external BenQ EQ2420 display with the HMDI connections from both laptop and the display. I was previously using a DVI-D to minidisplay with the adaptor. Worked perfectly. At home I could connect the laptop to the TV w/o any problems.But when on the external display, an other story...
Result -- Display was showing no cable connected. I've seen some people here saying that they are having the same experience.
I could see the BenQ display in my systems prefs in the display option and also I saw it in my system report so I knew it was there just
that I didn't get any "signal" or anything.
This is were I got annoyed and ******, asking google for the answer and ended up here...
Solution -- Since I had have the DVI-D connected before it turned out that my external display did not automatically switch the port to
where my HDMI cable was connected and I had to do it manually just pressing the side of my display 2 times until it showed the correct
line-in for HDMI.
So, if there are people out there seeing the same "problem" as I. Try this first before start complaining about random things.
Cheers
