MacBook Pro 2016 USB-C to HDMI (Apple Multiport Adapter) problem My MacBook won't display anything connected through an USB-C Digital AV Multiport Adapter to HDMI display. I have tried with many (Dell, Samsung, Acer, Iyama, LG, from the local store) external displays.

Sometimes (after a restart, with SMC reset) it works for 5 seconds and suddenly stops. It does not even show the external display in the preferences.

Do you know how to fix it?

Hardware details:


USB-C Digital AV Multiport Adapter from Apple (MJ1K2ZM/A)
MacBook Pro (13-inch, 2016, Two Thunderbolt 3 ports)
2,4 GHz Intel Core i7
16 GB 1867 MHz LPDDR3
Intel Iris Graphics 540 1536 MB


I have noticed one thing - when I disconnect the HDMI cable the display says "No HDMI Cable" when I connect it back it says "Entering Power Save Mode".
I had to replace the adapter. It seems the one I was using was broken. Now everything is fine and the display displays :).
