HDMI output not working on new MacBook Pro 2016 Touch Bar I am trying to get HDMI output working (both on tv and my normal HD screen) from my new mac. The device only has USB-C ports, so I bought two types of converters (not official from Apple, but didn't think that would matter): 


This adapter, that I use with a regular hdmi cable. 
This adapter with integrated cable. 


None are recognised by the Mac. I've tried hitting the option key and detecting displays, but none show. I've also tried plugging in the usb cable that is attached to the last cable in the tv too, no luck. I see that the first adapter has a power slot too, I can try to plug in a usb power source there? 

I've also just updated Sierra, no luck. 

Any other suggestions? My vga / usb-c adapter works fine. 

Is there any logfile or so that I could check to see if the device gets recognised?
Based on everything you have described, it sounds like the problem is between your MBP and the TV(s).  I am not a fan of no-name adapters like the one you linked in your question. 

I have personally recommended this Anker USB-C to HDMI adapter to a family member with excellent results.



It's got high ratings, an 18 month warranty and supports 4K at 60Hz.  The adapters you referenced didn't support that level of resolution (1080p looked to be the max).
