Connect the HDMI/USB-C transmitter to your laptop.
Open the i3ALLSYNC app on your i3TOUCH, i3HUDDLE or i3SIXTY.
When a green light appears, the device is ready to mirror.
Press the main button to mirror, the main button will change into blue.
If you would like to stop the sharing, just click the main button again and the light will change back green and mirroring will stop.
For macOS users, please adjust your sound output to “DisplayPort” if you are using a USB-C transmitter, or “HDMI” if you are using an HDMI transmitter.
