Hi @Fries,
To share your desktop with in-room participants outside of a Teams meeting, connect your personal device to the appropriate cable connected to the room console. Depending on your room settings, your screen may be shared automatically, or you may have to select Share on the room console. Depending on your device settings, you may see different content sharing options.
You can also cast content from your personal device. To learn more, see casting from a mobile device or casting from a desktop.
There are three ways to share with both in-room and online participants from a personal device:
- Join the meeting on your personal device and select Share, then the item you want to share.
- Connect your personal device to the cable connected to the room console. Depending on your room settings, your screen may be shared automatically, or you may have to select Share> Connected device > Share on the room console.
- Cast content from your personal device.
