Connecting a second screen to your Board Pro or Desk Pro gives you the enhanced meeting experience by allowing you the flexibility to have all the presentation info on your second screen while still having all the meeting abilities on your Desk primary screen.

When only a singular connection is established (HDMI or USB C only), the content will appear on the secondary screen only. The Board Pro or Desk Pro screen will not be impacted and will continue to show your meetings and events, as well as allow you to interact with it.

This means that when you are looking at the main screen and talking to people you maintain eye contact with the other people on the meeting, reducing fatigue. It also allows you to prepare more accurately for sharing content. If you preview content it will appear on the second screen, allowing you a chance to prepare your window before you share. If you are receiving content from the far end and preview content it will turn the Board Pro or Desk Pro into a single screen system, with the received content shown on the primary screen.

The default setup is that the second screen is reserved exclusively for content being shared into the meeting.

When not in call, the second screen will always show wallpaper/clock.


Setup recommendation:

We recommend that you place the extra screen between your Desk Pro and your laptop, with the ability to charge the laptop via USB C from the Desk Pro.

You enable the HDMI out feature from the Device Settings menu, under Screen and video. Select Display and toggle HDMI out.


The first time you enables the HDMI out feature on your device, it will immediately reboot. When it starts up again, your device will automatically detect inputs through the HDMI port.

If the HDMI connection is later disconnected, the device will revert to a single screen system without requiring any additional user intervention.

The feature is configurable so you can set up the system to duplicate on both screens if needed (teaching purposes), or extend the meeting across both screens.

You can configure the HDMI out feature setup from the device's local web interface or from Control Hub. See the Device Configurations article for more information. The API configuration is: xconfiguration Video Output MirroringType: LastOnly, Mirror, Multiscreen.

The HDMI out feature provides three primary setups: LastOnly Mode, Mirror Mode, and Multiscreen Mode.

LastOnly mode:

LastOnly mode is the default set up for Desk Pro.

When only one source is connected the presentation only appears on one screen, this being the external monitor plugged into the device.

If a second presentation is started, it will show up on the Desk Pro, thus having both presentations on at the same time.

When HDMI Out is enabled, the monitor role is defaulted to PresentationOnly. This reserves the connected screen for presentations, both previews and in call / meeting. All participants will be contained on your device and only presentations will be shown on the connected screen. This allows you to continue with your work on the connected screen while communicating with participants on your device.

Multiscreen mode:

This is the default behavior for Board Pro.

With this mode, a preview will take over all available screens.

Mirror mode:

Mirror mode shows the presentation on both screens, while the main display will exclusively show call controls, notifications, and other UI elements.

This setup is intended for teaching scenarios and in large auditoriums where the main screen is difficult to see.
