Microsoft Teams does not currently provide a built-in way to cast a meeting directly to any television, Chromecast, Roku, or Apple TV. In Microsoft’s documentation, the Teams Cast feature is designed for a nearby Microsoft Teams Room (MTR) or Surface Hub.
A regular television can still show a Teams meeting if it is connected to a Teams Rooms system or used as an external display for your computer. For a non-Teams-room setup, the practical options are Miracast from a compatible Windows laptop or a wired HDMI connection.
What you need before casting Teams
Choose the method that matches your equipment:
| Setup | Best method | Important requirement |
|---|---|---|
| Teams Room or Surface Hub nearby | Teams Cast | The room must be discoverable and configured for casting |
| Teams Room on Windows or Surface Hub | Miracast | Miracast must be enabled and the room needs a Teams Rooms Pro license |
| TV connected to a room computer or console | HDMI | Connect the laptop to the room system’s HDMI cable |
| Ordinary smart TV with Chromecast, Roku, or Apple TV | No documented Teams Cast destination | Use HDMI, or use Windows wireless display if the TV supports Miracast |
For Teams Cast, Microsoft supports Teams Rooms on Windows, Teams Rooms on Android, and Surface Hub. The Teams device must also have Bluetooth beaconing enabled, and your account generally needs to be in the same Microsoft 365 tenant as the room. A federated tenant relationship may be required for cross-tenant access.

- Open the Teams desktop app and sign in.
- Select Settings and more, the three-dot button next to your profile picture.
- Select Cast.
- Select the nearby Teams Room.
- Select Next.
- If Teams detects a scheduled meeting in that room, choose either Just cast or Cast and join a scheduled meeting.
- Select Next again.
- Choose what to send: your screen, a window, a specific file, or supported PowerPoint Live content.
- Select Cast.
The computer joins the cast session with audio turned off. This helps prevent echo when the room’s speakers and microphones are being used.
What “Just cast” means
Just cast sends your selected content to the room without joining a scheduled meeting. Cast and join a scheduled meeting casts your content and joins the meeting associated with that room.
These choices do not always appear. Microsoft says they are shown only when you have a meeting scheduled in that room. If there are no meetings scheduled for the rest of the day, Teams will not display those options.

A wireless icon beside a room name indicates that the room can automatically accept casting when casting is enabled on the room device. If automatic acceptance is disabled, someone must accept the request on the Teams Rooms device.
For the smoothest experience, the room administrator should enable Automatically accept proximity-based meeting invitations. This setting works only when the wireless icon is displayed beside the room name.
Method 2: Cast Teams from a phone
The Teams mobile app can project an entire phone screen to a nearby Teams Room. This is different from sending only a presentation: everything visible on the phone, including notifications, is projected.
- Install and sign in to the Teams mobile app.
- Turn on Bluetooth.
- Make sure both the phone and the Teams Rooms device are connected to the internet.
- Move within approximately 10 meters (32.8 feet) of the room device.
- In Teams, tap Cast in the navigation bar. If it is not visible, tap More.
- Tap the available Teams Room.
- Tap Project my screen.
- On an iPhone or iPad, select Microsoft Teams if prompted.
- Tap Start Broadcast.
Microsoft provides a separate procedure for casting a PowerPoint presentation from a mobile device. Use that option when you want to share a presentation rather than mirror the whole phone.
While mobile casting is active, you cannot answer a call, join a meeting, or switch to another Teams account. To stop projecting, tap the pill-shaped status icon at the top of the screen and then tap Stop.
Method 3: Use Miracast from a Windows laptop
Miracast is useful when you want to mirror or extend a Windows laptop to a compatible Teams Room display. It is documented for Teams Rooms on Windows and Surface Hub, not as a general Teams connection to every smart TV.
The room must have a Teams Rooms Pro license, the administrator must enable Miracast, and your laptop must support Miracast. You also need to be physically in the room with the display turned on.

- Press Windows key + K on the laptop.
- In the Cast panel, select the Microsoft Teams Room.
- When prompted, choose Duplicate your screen or Extend your screen.
- To disconnect, press Windows key + K again and select Disconnect.
Duplicate shows the same desktop on the laptop and room display. Extend creates a second display, allowing you to place Teams or presentation content on the TV while keeping notes on the laptop.
Windows may also show Allow mouse, keyboard, and other input from this device. Allowing it lets the room display send touch, pen, mouse, or keyboard input back to the laptop. Miracast audio behavior varies by device, and some DRM-protected streaming applications may not display correctly.
Method 4: Connect the laptop with HDMI
HDMI is usually the most dependable choice when wireless casting is unavailable. It also works with a television connected to a Teams Rooms system or with a TV used as a direct external monitor.
- Connect the laptop to the HDMI cable attached to the Teams Rooms console or room system.
- Wait for the room display to detect the connection.
- If the content does not appear automatically, select Share on the room console or system.
- During a meeting, select Share > Connected device > Share.
On Teams Rooms on Android, the room system may provide a Share system audio switch for content from a connected device. In a room with two displays, use Duplicate content to show the shared content on both screens, or Stop duplicating to return to the normal layout.
If your laptop has only USB-C, you may need a USB-C-to-HDMI adapter. For a normal TV, connect the adapter to an HDMI input, change the TV to that input, and use your computer’s display controls to duplicate or extend the screen.
Why your Teams Room does not appear
If the room is missing from the desktop or mobile Cast list, check these common causes:
- It is not a supported destination: a normal TV, Chromecast, Roku, or Apple TV will not appear in the Teams Cast list.
- Bluetooth beaconing is disabled: Teams uses proximity information to discover nearby room devices.
- The room is not configured for casting: the room administrator may need to enable casting or Miracast.
- Your account lacks access: the signed-in account may be outside the room’s tenant or lack the required device relationship.
- You are too far away: for mobile casting, move closer to the room; Microsoft specifies a range of about 10 meters.
- The room type is unsupported: the documented Teams Cast targets are Teams Rooms on Windows, Teams Rooms on Android, and Surface Hub.
- The room display is off: this is especially relevant when using Miracast.
For Windows Miracast, press Windows key + K. If the room is not listed, Miracast may be disabled on the room device or unsupported by the laptop.
Joining the meeting without creating an echo
A room meeting normally appears on the console when the organizer adds the room as the meeting location. If it is missing or has no Join button, try one of these options:
- Invite the room to the meeting.
- Scan the QR code shown on the room console.
- Select Join with an ID.
- Add the room from your personal device.
If you join from your laptop or phone and then accept the room call, turn off audio on the personal device first. Otherwise, the room and personal device can create an echo. In the Teams pre-join screen, a nearby room may appear as (suggested) beside Room audio. If the room is already in the meeting, choose Don’t use audio for Windows-based rooms or Audio off for Android-based rooms.
How to stop casting and end the meeting
To stop sharing from the room console, select Stop sharing.

On the casting computer, selecting End meeting ends the meeting for both the computer and the room. Selecting Leave in Teams on the computer may not end the room’s session. In that case, end the call separately on the Teams Rooms device.
For mobile projection, tap the status pill at the top of the screen and select Stop. For Miracast, press Windows key + K and select Disconnect.
Can you cast Teams to Chromecast or Apple TV?
Microsoft’s current Teams casting documentation does not list Chromecast, Roku, Apple TV, or an arbitrary smart TV as a Teams Cast destination. If one of these devices is connected to a TV, use a supported screen-mirroring feature outside Teams where available, or connect the computer directly with HDMI. A Windows laptop and a Miracast-compatible television may be able to use Windows key + K, but that is Windows wireless display functionality rather than Teams Cast.

FAQ
Can I cast Microsoft Teams directly to any TV?
Not through the Teams Cast feature documented by Microsoft. Teams Cast targets nearby Teams Rooms on Windows, Teams Rooms on Android, or Surface Hub devices. For an ordinary TV, use HDMI or a compatible Windows wireless-display method.
Why is Cast missing from Microsoft Teams?
On desktop, select Settings and more next to your profile picture and look for Cast. If it is absent or no rooms appear, the destination may not be a supported Teams device, Bluetooth beaconing or casting may be disabled, your account may not have access, or the room may belong to an unrelated tenant.
Can I cast Teams from an iPhone?
Yes, if a nearby supported Teams Room is available. In the Teams app, tap Cast, choose the room, tap Project my screen, select Microsoft Teams when prompted, and tap Start Broadcast. The entire phone screen, including notifications, is shared.
What is the most reliable way to show Teams on a TV?
A wired HDMI connection is generally the least dependent on room settings and wireless discovery. Connect the laptop to the TV or Teams Rooms system, select Share or Connected device on the room console when necessary, and choose the correct HDMI input.

The Bottom Line
Bottom line: Teams Cast is for Teams Rooms and Surface Hub, not directly for consumer TV streaming devices. Use Settings and more > Cast when a supported room is nearby, Windows key + K for enabled Miracast rooms, or HDMI when you need the most predictable connection to a TV.
