Some manual calculations will be required to determine the size of the canvas depending on the number of screens, the screen resolutions, the screen arrangement and the screen bezel sizes. Use your favorite tools (paper and pencil or a spreadsheet) to plan out the canvas size before proceeding.
Start creating your new arrangement by creating a new “Screen” in the Management->Screen section of EnGage. Select the “Screen Settings” folder and the “add” icon on the toolbar.
Check the “Are you using a Video Wall” option. Then enter the number of screen that will be used for the multiple screen setup, the panel type (manufacture type) and height/width of the canvas, in pixels.
The canvas size cannot be changed later and must be large enough to accommodate for all of your screens and the bezel correction between the screens. Click on the “Next” button to proceed to the next step.
Enter a name for the screen arrangement. Add any panel control options that are required and click “Save”.
Select the screen arrangement that was created in the previous step and click on the “Layout Editor” button.
The right side of the window will be the canvas, at the dimension as defined in the previous step. The left of the window will have the screen selections that can be used on the canvas. Use the scale to zoom in or out on the canvas. It is easiest to start in “Full” view of the canvas, add your screens and then zoom in to fine-tune the location of the screens within the canvas.
Open up the screen folders on the left and begin dragging your screens onto the canvas. Continue dragging screens into the canvas until all the desired screens have been added. Drag the screens around the canvas to lay the screens out as required.
In the example below, a non-standard screen arrangement has been created with both portrait and landscape screens including gaps between the screens for bezel correction.
If the screens [resolutions] you’re using are not available in the screen selection, use a custom screen size and define the resolution within the screen on the canvas.
Click on the “Gear” within a screen to set the details of the screen such as index, placement co-ordinates, screen resolution and “flip” option.
The new screen arrangement can then be assigned to a site in the same way a screen is assigned. Use the layout editor to create a screen layout that matches the screen arrangement.
The index numbers will correspond to the video outputs on the back of the EnGage player. Changing the index numbers will alter how the screens in the arrangement are mapped to the physical video outputs on the back of the player.
Each screen has a number of settings:
- Index. The index is the screen number that corresponds to a physical video output on the player. Changing the index will change which video output the screen is connected to.
- Flip. The flip option enables users to invert the video 180 degrees.
- Left/Top. These fields define how many pixels from the left boarder of the canvas and how many pixels from the top board of the canvas, the screen is placed within the canvas. This is a good method for fine tuning the locations of the screens within the canvas. These values can also be changed by typing them directly into the screen however, if the screen is very small within the editor, the boxes to type in these values may not be available.
- Width/Height. These fields define the size of the screen in pixels. Only “custom” screens will have the option to change these values.
The back stencil button enables users to add an image from the content library that can be used as a background stencil over which the screens can be arranged. This feature makes arranging screens easier when a layout schematic is provided as an example arrangement.
Possible Issues and Limitations
- If a Screen Layout does not cover all portions of a Screen Arrangement, the background image will be shown in those portions during content playback. By default, the background is black.
- When creating/encoding content, be aware the most content today is recorded at a maximum resolution of 1920x1080. If this content is stretched across multiple screens it may not look as sharp as it would on a single screen because of the scaling required to span multiple screens.
- Re-encoding content to higher resolutions will not increase the quality of the content.
- Assigning a Screen Arrangement to a single output player will be have unpredictable results and is not supported.
