Please read the steps below:
- Join Google Meet from teacher cart PC.
- Join Google Meet from TV/Chromebox.
- Mute your mic from the TV/Chromebox within Google Meet
- Turn off the volume on the TV using the ROKU remote. The mute button is on the side.
This will allow your virtual students to appear on your TV and still give you the ability to speak to them (through webcam at your teacher cart) and present anything via your teacher PC.
