Creating and Configuring Video Wall

Userful's video Wall feature enables users to group multiple displays to form a single large canvas. This makes it easy for a single Userful server to support content translation to entire screen area as a single display. Userful's video wall feature supports a variety of configurations (e.g. 2×2, 3×3, 5×5 etc.) and layouts (equidistant grid, or free-layout and artistic).

To create a video wall, click Control Center > Mapping > New Video Wall button. The video wall configuration window allows video wall integrators to adjust the video wall size, layout, bezel correction, and color calibration.

The content that you want to show on the displays depends on what source the video wall is mapped to. This is discussed in a later step.

Please Note: The instructions provided here are sufficient for creating a video wall.

Grid Layout

Grid Layout allows video wall integrators to configure the video wall in an equidistant grid or in synchronized rotation. This layout allows users to adjust the video wall size (number of displays), display assignment, padding between displays and color calibration in an equidistant layout.

    Layout

    Grid Layout

    The default video wall size is 4 displays with 2x2 configuration. To add/delete rows or columns, use the +/- buttons next to Rows/Columns.

    To rotate video wall in a given direction, select the rotation option from the drop-down.

    To assign display IDs on displays, click the drop-down select-box in the center of the "display" and then select the ID of the display that will be in that position of the video wall. The display ID will have a green color if it is unmapped, orange color if it is assigned to any other source and red color if it is assigned to another video wall.

    The "Display ID" will automatically be visible on the actual physical display in "Red" color and it will change its color to "Green" if the display is selected.


    Flip Top Row
    Flip Top Row

    Grid Layout video walls allow users to Flip Top Row to create uniform grid spacing with displays

    • Assign a display by selecting the display ID from the drop-down list in the center of the display
    Use "Shown IDs" button to view the ID on the physical displays
    • Enable Flip Top Row under Rotation - Normal Landscape as shown in the image to the right to view the effect of flip on the physical displays
    • Click "OK" to complete the process and create video wall


    Note: User can also Flip Bottom Row, Flip Left Column and Flip Right Column depending on the Rotation selected from the drop-down

    Spacing

    "Spacing" refers to the space between visible portions of the image; in the context of the video wall. This effectively implies the horizontal and vertical spacing taken up by the display's bezel. For best results, padding should be adjusted so that the complete content is visible. To assist with this fine-tuning process, Userful has provided "Diamonds" test pattern that is displayed on the video wall. You can use +/- buttons next to the vertical and horizontal padding sliders to adjust spacing. Click on the “Chain” icon to link the padding sliders and set the horizontal and vertical padding to the same value.

    Color Calibration

    Color Calibration

    Color Calibration allows you to adjust the color characteristics (i.e. RGB color scheme, Brightness and Contrast) of any display in the video wall configuration. This effectively implies adjusting the color tolerance and intensity of displays in the video wall setup, thereby enhancing the visual illusion of a single large uniform display. To do color correction:

    • Click Color Calibration button
    • Enter values or use mouse wheel to select values for color scheme, brightness and contrast respectively.


    Artistic Layout

    Artistic Layout available under "Ultimate" and "Creative" version of Userful solution enables users to configure video wall in free layout and create more appealing and interesting display arrangements.
    Artistic Layout provides following features:

    • Ability to move and place multiple displays at desired position
    • Rotate the selected display at desired angle along a common origin point
    • Calibrate the video wall to identify and assign physical display placements
    • Specify the display panel size
    • Specify the rotation-offset


    To configure Artistic Layout, click Control Center > Mapping > New Video Wall > Switch to Artistic. This video wall configuration window allows video wall integrators to define, adjust, and calibrate video walls.

    Layout

    Artistic Layout

    The default video wall size is 4 displays with 2x2 configuration. To add a display, use the “Add Display” button and to remove a display from the canvas, select the display and click “Trash” icon. Confirm your action by hitting "OK".

    To define what displays make up the video wall, click the drop-down select box in the center of the "display" and then select the ID of the display that will be in that position of the video wall.
    Note: The display ID will have a green color if it is unmapped, orange color if it is assigned to any other source and red color if it is already assigned to another video wall.

    To rotate the display in the desired position, specify the "Rotation-Offset" and click on the corner rotate buttons of the selected display (e.g. specify the value as 20 or 20.5)
    Note: Default value of "Rotation-Offset" is 90 degrees. You can also use "Shift + [" or "Shift + ]" to rotate the displays with an offset of 10 degrees.

    You can also configure individual Display Settings to mix and match displays of different sizes at different rotation angles by selecting a display and clicking on the gear icon.

    Spacing

    Calibration enables video wall integrators to adjust the padding, placement and spacing of video wall displays in real-time scenario. To assist with fine-tuning/calibration, click on non-calibrated display and drag it left/right using mouse or “arrows” keys on the keyboard. To rotate a display, select a display and click upwards or downwards arrow to rotate clock-wise or anti-clockwise (see image to the right). Repeat this step for every non-calibrated display.

    Note: You can also use "Ctrl"+ Mouse clicks to select multiple displays or "Ctrl+A" to select all.


    Color Calibration

    Color Calibration

    Color Calibration allows you to adjust the color characteristics (i.e. RGB color scheme, Brightness and Contrast) of a display. This effectively implies adjusting the color tolerance and intensity of displays in the video wall setup, thereby enhancing the visual illusion of a single large uniform display. For color calibration:

    • Click on the Color Calibration button
    • Enter values or use the mouse wheel to select values for the respective color scheme, brightness, or contrast.


    To change the video wall configuration, click an existing video wall to open Video Wall Zone Settings window. Click "Calibrate Video Wall" button and do the changes.
