Overview

The XC2055 and XC4055 are the first BrightSign media players to have multiple independent video outputs (the XC2055 has two HDMI^® outputs, while the XC4055 has four HDMI outputs). This page describes how to configure these outputs with BrightSign APIs.

...

• name: On the XC platform, the possible values are HDMI-1, HDMI-2, HDMI-3, or HDMI-4.  The number of array items depend on the number of outputs:

  • The XC2055 has two outputs, HDMI-1 and HDMI-2

  • The XC4055 has four outputs, HDMI-1, HDMI-2, HDMI-3, and HDMI-4

  • The name tells the system which output is associated with the rest of the settings in that entry within the roAssociativeArray (the order of the HDMI outputs is not important).

• video_mode: The videomode can be either

  • A known BrightSign format videomode (for example, 1920x1080x60p)

  • A full modeline as described in Applying a Custom Resolution#ModelineFormat

  • auto which differs slightly from previous platforms. auto isn’t recommended when using multiple outputs because the canvas positions are fixed and so if a screen uses an unexpected resolution then it won’t be positioned correctly in the canvas.

• display_x and display_y: The position of the screen within the overall canvas. The origin 0,0 is the top left corner, and each screen can be positioned relative to that. This allows for bezel compensation as gaps can be left on the canvas between screens.

• transform: normal, 90, 180 or 270. Each screen can be rotated independently. When a screen is rotated, it rotates all of the content including video. If a single screen is set to 1920x1080x60p and 90 then the screen is running in portrait mode and all of the firmware will run as if the screen is set to 1080x1920x60p with video and graphics all rotated.

• enabled: Whether the screen is enabled for output. To turn an output to off, set enabled = false. No other fields need to be set.

Videomode plugins allow you to set custom multi-screen video modes. This feature has been updated to support multi-screens in BrightAuthor:connected 1.13.0 and later and BrightAuthor 5.0.1.1 and later. You must match the graphics mode that you set when authoring the presentation.
