Content sharing in a meeting room means showing a laptop screen, document, video or whiteboard on the room's display, and usually sending it into the video call at the same time so remote participants see it too. You can share with a cable (HDMI or USB-C), wirelessly (casting from the meeting app, AirPlay, Miracast or a wireless presentation system), or by joining the meeting from your laptop and sharing from the app.
The main ways to share
| Method | How it works | Shares to the call? | Best for |
|---|---|---|---|
| HDMI ingest | Laptop plugs into an HDMI input on the bar, controller or table box | Yes, on appliance rooms | Any laptop, no software |
| USB-C (DP Alt Mode) | One USB-C cable carries video to the room | Depends on the setup | Modern laptops; BYOD rooms |
| Meeting app share | Join the meeting on the laptop (audio muted) and share screen | Yes | Teams, Zoom, Meet users |
| Platform casting | Teams casting, Zoom Rooms direct share, Google Cast for Meet hardware | Yes, on that platform's rooms | Users on the room's platform |
| AirPlay / Miracast | Built into Apple and many Windows/Android devices | Depends on receiver | Guests, phones and tablets |
| Wireless presentation system | Dongle or app sends the screen to a receiver on the display | Local display; into the call with some setups | Mixed devices, guests |
| Whiteboard camera | Camera captures a physical board as content | Yes | Brainstorming, teaching |
Local sharing vs sharing into the call
- Local only: the screen shows on the room's display, but remote participants don't see it. Common with a plain HDMI cable to a TV, or a wireless presentation system on its own.
- Into the call: the room system takes the content and sends it to the meeting. Appliance video bars and Teams/Zoom room controllers with HDMI ingest do this automatically.
For hybrid meetings, always make sure shared content reaches the call. See hybrid meeting setup.
Why it matters
Content is the main reason people book a room with a screen. If sharing takes more than a few seconds, or needs an adapter nobody can find, meetings start late and people stop using the room.
What to look for when buying
- HDMI ingest at the table or on the bar. For example, the Logitech Tap has HDMI ingest for one-cable wired sharing in PC-based rooms. Note that the Logitech Tap IP has no HDMI input; use the bar's input instead.
- One-cable BYOD for USB-C laptops. Logitech Extend adds single-cable USB-C to Rally Bar rooms.
- Wireless options for guests. The Yealink RoomCast E2 supports AirPlay and Miracast and shows up to 4 sources at 4K60. The Jabra PanaCast 50 Video Bar System supports HDMI input plus AirPlay on Zoom and Teams casting on Teams.
- HDCP awareness. Copy-protected video (streaming services, some Blu-ray players) often won't share through meeting room inputs. Logitech, for example, states HDCP content can't be shared through the Rally Bar Huddle's HDMI input.
- Whiteboard sharing. The Logitech Scribe shares a physical whiteboard as content.
- Platform support. Each platform has its own casting feature. See Teams Rooms content sharing.
Common problems
- Black screen from a laptop: wrong input or HDCP. See how to fix HDMI no signal on a meeting room TV.
- Remote people can't see the content: the share is local only. Share from the meeting app or use the room's HDMI ingest.
- Echo when joining from a laptop to share: mute the laptop's mic and speakers. See how to fix echo on a conference call.
