Hello Microsoft team,

We are using 02 TVs for Teams on Lenovo Thinksmart Core Gen2 on Win11 IOT

Model: 12X2S00011

With Teams Pro account and dual monitor mode, can we duplicate content on both displays while local presenting?

Thank you.

Hi @Ryder Nguyen
Thank you for posting your question in the Microsoft Q&A forum.
I understand you would like to duplicate the same content on both displays while using dual monitor mode during a Teams meeting. Here’s what you might concerned:

Current Teams Rooms Behavior

In dual monitor mode, Teams Rooms is designed to extend the display:
- Primary screen shows shared content (like presentation, screen share).
- Secondary screen shows meeting participants or gallery view.
This layout is by design and ensures the best experience for hybrid meetings.

Can Both Screens Show the Same Thing?

No, during a Teams meeting you cannot make both screens show the same content.
This is because Teams wants to keep one screen for people and one for content.

When Can You Duplicate Screens?

You can show the same content on both screens only when you are not in a Teams meeting, for example:
- When you connect your laptop with an HDMI cable for a local presentation.
- When you use Bring Your Own Meeting (BYOM) mode.

Workarounds (Not Officially Supported)

Forcing Windows to duplicate displays or using an HDMI splitter may achieve this, but these methods are unsupported and could impact security or device stability.

Thank you for your cooperation. I'm looking forward for your reply.

Dear Alex,

Many thanks for your answer.

Yes, I meant only for local presenting, for example, as below.

You can show the same content on both screens only when you are not in a Teams meeting, for example:

When you use Bring Your Own Meeting (BYOM) mode.

Hi @Ryder Nguyen
Thank you for update.
For local presenting only (outside a Teams meeting), you can duplicate the content on both displays, but it requires changing the display mode at the Windows level because Teams Rooms dual-monitor mode is designed for extended view.

You can try:

Option 1: Use Windows Display Settings

Exit the Teams Rooms app or switch to BYOM mode.

On the ThinkSmart Core, right-click the desktop and select Display settings.

Under Multiple displays, change from Extend these displays to Duplicate these displays.

Apply changes. Both TVs will now mirror the same content.

Option 2: HDMI Splitter (Hardware)

Connect an HDMI splitter to the Core’s HDMI output so both TVs receive the same signal.

This works even during local presentations without changing software settings.

Note: This is not officially supported by Microsoft and may affect resolution or HDCP compliance.

Important Notes

These methods only apply when not in a Teams meeting. During a meeting, Teams Rooms enforces extended mode for optimal experience.

Unsupported workarounds (like forcing duplication during a meeting) can cause stability or security issues.
