We can confirm that only the USB-C port next to the connection pins supports pass-through charging and video output. 

The USB-C port near the 3.5mm headphone jack was designed for data transfer purposes only and will not allow for pass-through charging or video output. 

We hope this information has been able to provide a bit of clarification and guidance.
