Thank you John.

Since then I have bought a micro-HDMI to HDMI cable, and now it works.
So it’s really the micro-HDMI to VGA adapter that doesn’t work.

About the console problem, I’ve found that TXD and RXD were inverted...

I’m now fighting with Debian installer which is searching a CD reader. But that’s an other story.

Thanks all for your help. And I hope these informations will help others as minnowboard max is being more and more used.

Regards
