I am using a MBP 13" late 2016 without touchbar. I use a CableMatters USB-C dongle to connect a VGA monitor to my laptop and it works.

However, when I connect an external projector to my MBP (I tested on two different projectors) using the same dongle

  • there is a black screen on the laptop
  • then in a few seconds, it says there is a problem in different languages and press any key to restart

Is there a problem with the dongle or the laptop? I am confused as the dongle works fine with a standard VGA monitor.
