# Video settings

Go to the section to change the settings of connected screens, monitors, and certain general settings for all video layouts.

# Main Camera

In the Main camera section, you can select the camera to use; it displays a list of all available cameras connected via USB, HDMI, VNC, RTSP, NDI.

By enabling the Auto-framing option, the image from your camera will be automatically cropped to keep you always in the center of attention.

Face Detection highlights all people in the frame with a colored box.

In the Device Management section, you can add RTSP and VNC sources from the address book. Afterwards, these sources can be used as your camera.

# Monitor Management

In this section, you can configure the connected displays.

/docs/group-user/media/monitor-management/en.png

If your configuration uses two screens, you can choose which one will be used as the primary or secondary display.

In the HDMI Mode (or DisplayPort) section, you can set the resolution and frame rate for the terminal's display interface.

The Rendering resolution item is responsible for the resolution of the video layout in calls (Auto, FullHD 1080p, and UltraHD 2160p).

Below, you can Define video outputs and perform a Monitor test (useful for screen calibration).

# Video Layout

Here you can customize the video layout in calls.

By default, the Hide self-view option is enabled; deactivate it to see your self-view in the video layout.

To display microphone sensitivity in participant windows, activate Show volume indicators.

/docs/group-user/media/volume_level/en.png

Scaling mode – mode for cropping participant video windows. Available options:

  • Auto – depending on the participants' video, the terminal automatically selects the cropping mode;

  • By video size – participants' video windows are fully displayed in the video layout;

    /docs/group-user/media/scaling_video/en.png

  • Fit to window – participant video windows are adjusted to fit the width of your screen.

    /docs/group-user/media/scaling_window/en.png

If you activate the Use overlay mode option, participants' videos will be displayed over the priority video window.
