Visual representation of the CEC Control page: CEC control options are shown, including device IDs and commands like Power, Volume, and Mute.

Video Wall Page

This page is used to configure a group of outputs to function as a video wall.

Use the Video Wall Setting controls to arrange displays:
- Adjust the Rows and Columns sliders to change the screen arrangement for proper Drag-and-Select.
- Change the Available slider to set how many outputs will be used for the Video Wall.
- Click the "Set" button to apply the Screen configuration.
Use the left mouse button to drag-select screens for video wall mode; selected screens will appear bright blue.
Use the right mouse button to open a context menu.
Select "Screen Stitching" from the menu to program the video wall mode; selected screens will then appear bright green.
To change the displayed image, use the methods detailed in the "Controlling the Matrix Switcher" section, or right-click to open the pop-up menu and select the desired input from the "Input Select" menu option.

Visual representation of the Video Wall page: The Video Wall interface displays controls for Rows, Columns, Available, and a grid representing screens that can be selected and configured for a video wall.

Repeating steps 2-5 with a different set of outputs allows the creation of a second video wall. Changing the Rows, Columns, and Available sliders will automatically delete the current video wall setup when the "Set" button is clicked.

Visual representation of an example video wall setup: An example shows a video wall configuration with 3x3 screens, and another example illustrates a more unusual setup with two video walls of 1x3 and 2x2 configurations.

Video Wall Context Menu

Right-clicking on any of the screen icons displays the following context menu:

Screen Stitching: Connects the selected screens into a video wall configuration.
Cancel Stitching: Returns the Video Wall configuration to normal outputs.
Screen x - Cancel Stitching: Removes a single screen from the video wall to allow displaying another full-frame image within the video wall configuration.
Input Select: Use the sub-menu to select the input to display on the video wall or the secondary input image.
Output Select: Available only for screens not assigned to a video wall mode.
Output Type: Available only for screens not assigned to a video wall mode.
Output Format: Available only for screens not assigned to a video wall mode. It allows setting of the output resolution for the selected screen output.
Mirror: Four sub-options: OFF (default), H (Horizontal), V (Vertical), H+V. When H+V is selected, a 180° rotation with the selected screen can be applied.
Test Pattern: When enabled, the output will display a Color Bar pattern.

Bezel Setting

The Bezel Setting section allows the entry of values to compensate for the display bezel thickness. These values can be entered either as pixels (Type A) or as millimetres (Type B).

Type A Bezel Settings: The image size will be adjusted to allow for the number of pixels entered in each entry box. Click the "Set" button to view the effect of the new values.
Type B Bezel Settings: The image size will be adjusted to allow for the Inner and Outer display dimensions as entered in each entry box. Click the "Set" button to view the effect of the new values.

Visual representation of bezel compensation: Images demonstrate the effect of "No Bezel Compensation" versus "Correct Bezel Compensation", showing how the latter aligns images across multiple displays without gaps.

Layout Save/Load

The Save Scene/Layout and Load Scene/Layout buttons allow a video wall configuration to be saved or recalled at any time. Up to 10 configurations, each with their own name, can be saved or recalled. When saving, each Scene can optionally be given a name to identify that video wall scene setup.
