Configuring Video Output

Configuring Video Output

After connecting video cables, set the video output parameters, such as output mode, resolution, refresh rate, and stretch mode. This will enable your endpoint to deliver a superior video experience.

Background

Table 1-11 lists the configurable video resolution and refresh rates of each video output port.

The higher the resolution, the clearer the image. The selected resolution must be the same as that of the connected display. The higher the refresh rate, the smoother the video. The selected refresh rate must be within the range supported by the display.

    • When Dual-screen is set to Disable, this port is used to display the local video or presentation in full-screen mode when the endpoint is not used in a conference and to display the remote video or presentation in full-screen mode when the endpoint is used in a conference. The default presentation output port is 2 HDMI.

    Do not set Video output port and Presentation output port to the same output port.

    An endpoint can be connected to two screens, which can be both untouchable (often named screens 1 and 2) or one touchable and the other untouchable.

    The output port policy specifies the way in which video and content are displayed on two screens. Three output port policies are supported.
    • 1 large pane+N small panes
      • One touchable+one untouchable: Video and GUI are displayed on the touchscreen and shared content on the other screen.
      • Both untouchable: Video and GUI are displayed on screen 1 and shared content on screen 2.
    • Fixed
      • One touchable+one untouchable: Shared content and GUI are displayed on the touchscreen and video on the other screen.
      • Both untouchable: Shared content and GUI are displayed on screen 1 and video on screen 2.
    • Dynamic
      • One touchable+one untouchable: Video or shared content that has started just now is displayed on the touchscreen with GUI, and video or shared content previously opened is automatically moved to the other screen.
      • Both untouchable: Video or shared content that has started just now is displayed on screen 1 with GUI, and video or shared content previously opened is automatically moved to screen 2.
      • Shared content will not be squeezed out from the two screens.

    The default value of Output port policy varies depending on the value of Collaboration under System Settings > GUI Display > GUI.

    When Collaboration is set to Disable, the default value of Output port policy is Fixed.

    When Collaboration is set to Enable, the default value of Output port policy is 1 large pane+N small panes.
