How to Connect Two Displays to a Video Bar

To connect two displays to a video bar, you need a bar with two HDMI outputs (most appliance bars for medium and large rooms have them). Run an HDMI cable from each output to each display, then turn on dual-display mode in the device or platform settings. With a USB video bar, the bar doesn't drive the screens; the laptop or room PC does, so connect both displays to the computer.

Which bars support two displays

Single-output examples: Logitech Rally Bar Huddle has one HDMI output, so it supports one display. For Windows Teams Rooms, the compute drives the displays; the Yealink MVC S40 kit's MCore 4 has three HDMI outputs.

Steps (appliance video bar)

1. Confirm dual-display support for your bar and platform (Teams Rooms, Zoom Rooms or Google Meet).
2. Mount both displays side by side at the same height, with the bar centered under or over the gap or under the primary screen. See dual display conference room.
3. Connect HDMI 1 to the left (primary) display and HDMI 2 to the right display, or follow the vendor's labeling.
4. Use quality HDMI cables rated for the resolution. For long runs, use active or fiber HDMI.
5. Power on both displays and set them to the right input. Enable HDMI-CEC if you want the bar to wake them. See HDMI-CEC.
6. Turn on dual-screen mode in the device settings or management portal (for example, Dual Monitor Mode on the Yealink A50).
7. Set the layout. Typically people on one screen, shared content on the other.
8. Test a call with content sharing to confirm content moves to the second screen.

Steps (USB video bar or BYOD)

1. Connect both displays to the laptop or room PC (HDMI, DisplayPort or a USB-C dock).
2. Connect the USB bar to the computer for camera and audio.
3. In the OS display settings, choose Extend.
4. In the meeting app, drag the meeting window to one screen and share content on the other.

Common mistakes

• Assuming every bar has two outputs. Huddle-class bars often have one.
• Mismatched displays. Different sizes or brands look odd and may scale differently. Use identical models.
• Wrong license tier. Microsoft lists dual screen support as a Teams Rooms Pro feature. See Teams Rooms Basic vs Pro.
• Bar under only one display in a wide room, so people look away from the camera. Center the camera if possible.
• HDMI input confusion. The bar's HDMI input is for sharing content, not for a second display.

Mounts for dual displays

The Logitech Rally TV Mount 2 supports single or dual 55-85 in. displays with Rally Bar 2 and Logitech AI cameras. See video bar mounts and conference room TV mounts.
