Creating and Configuring Video Wall


Userful Network Video Wall enables users to group multiple displays to form a single large display, thus enabling a single host PC to support one or more larger displays. This is possible because of the high performance and throughput of Userful's zero-client solution and the high-performance video splitter developed by Userful. Userful's Video Wall solution supports a variety of configurations (e.g. 2×2, 5×5, 1×10) and layouts (equidistant grid, or free-layout and artistic).

To create or video wall, click Control Center > Station 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 session container the video wall is mapped to. This is discussed in a later step.

Grid Layout

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

This is the default layout when you start configuring a video wall.

    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 at the lower right of the configure video wall window.

    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# that will be in that position of the video wall. Use the “Show Station ID” button to view the ID# on the physical displays.

    Note: The station ID number will have a green color if it is unmapped and will not be listed in the drop-down if it is already assign to another video wall.

    Spacing

    Video Wall "Spacing" refers to the space between visible portions of the image; in the context of the Userful Network Video Wall. This effectively applies 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 Mountains test pattern that is displayed on the video wall. To adjust spacing, use the vertical and horizontal padding sliders.
    You can 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 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. To do color calibration:

    • Under the Configuring Video Wall window, go to the Color option
    • Enter values or use mouse wheel to select values for respective color scheme, brightness or contrast.

    You can use Undo Color Changes to undo recent changes or Reset to Factory Defaults to set color scheme to default values.

    To preview all the changes done, click "Verify" option. However, if you want to edit existing settings, you can navigate back and forth using arrows(< >) to edit settings as needed. Hit "OK" button to save your configuration and settings.

    Artistic Layout

    Artistic Layout allows you to configure Video Wall in a free layout (display size and rotation) and create more interesting and creative arrangements.

    Artistic Layout provides following features:

    • Ability to move and place multiple screens
    • Use GPU-Assisted Acceleration Video Wall mode
    • Rotate the selected screen along a common origin point
    • Calibrate the Video Wall to identify and assign physical display placements


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

    Layout

    The default video wall size is 4 displays with 2x2 configuration. To add display, use the “Add Monitor” 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. To rotate a display, select the display and click "arrow" symbol.

    Note: The station ID number will have a green color if it is unmapped and will not be listed in the drop-down if it is already assign to another video wall.

    Spacing

    Through Spacing option, you can calibrate your video wall. Calibration enables video wall integrators to adjust the padding, placement and spacing of video wall displays in real-time scenario.
    Open an existing Artistic Video Wall, or create a new Artistic Video Wall and assign at least two displays. To assist with fine-tuning/calibration, click on non-calibrated monitor and drag it left/right using mouse or use “arrows” keys on the keyboard in order to adjust the padding space, rotation and to perform bezel correction. Repeat this step for every display. You can also use "Ctrl"+ Mouse clicks to select multiple monitors together.

    Note: To apply changes, hit "Apply" button available on the bottom right-corner of the Station Mapping page.

    Map Video Wall to a Session Container

    To map a configured video wall to a session container, simply drag-and-drop the video wall to the desired session type.

    Note: Session Containers that can be applied to a video wall are:
