USB-C tether and HDMI-out same time possible?

[Android Central Question]

For devices like the Samsung S8/S9, you can use a USB-C to HDMI adapter to mirror the phone screen on an external display.

Or, with a standard USB-C to USB-A cable, you can tether to a computer for data.

I have seen "docking station" type devices that have a USB-C connection to the phone, and then:

- USB-C for power only
- HDMI out
- USB-A for keyboard/mouse

My question is, would the USB-A port allow tethering to a computer, while simultaneously using the HDMI port to mirror the phone screen to a different device?

Yup, both ports should work simultaneously
