Overview

LED walls are comprised of modules which can be rearranged in multiple ways. The final arrangement usually doesn’t correspond to a standard display resolution, so you will probably need to make some adjustments to get the desired resolution. To do this, set a BrightAuthor:connected zone to the correct resolution, then configure your controller to scale standard resolutions from the player or apply a custom resolution to the player through a plugin. These methods are described below.

Create a Zone in BA:connected

See Display an LED Videowall in BrightAuthor for BrightAuthor (legacy) instructions

In BrightAuthor:connected, select a standard resolution and then create custom zone size that matches your output resolution. This will give you better image quality and a better representation of your content in BrightAuthor:connected.

To do this:

  1. Determine the LED wall dimensions and the number of HDMI outputs on your player.

  2. Create a new presentation in BrightAuthor:connected.

  3. In the Screens tab, select the number of screens based on the number of player HDMI outputs and how you want to display the content.

  4. Select a standard output resolution in Layout Settings that is equal to or larger than the desired display resolution.

  5. Switch to the Layout tab and set the pixel size and dimensions of the zone to correspond to the number of pixels and dimensions in your display. The size cannot exceed the maximum resolution for the player. See the example below.

Example

This is a BrightAuthor:connected layout for an LED wall that is 12064 pixels wide and 1872 pixels high. The BrightSign player has three 4K HDMI outputs, so this layout uses three screens.

Set the Resolution in the Controller

To scale resolutions in your controller, see the customer literature and/or videos for that product (Novastar, Samsung, etc.). Note that there are a range of models which have different maximum output resolutions (for example, some take full HD input, and some take 4K input). You can use a custom resolution or use regular resolutions with custom zone sizes (higher end controllers support this, lower end controllers may not).

Set the Resolution through Plugin

To set a custom video mode in your BrightSign player:

  1. Get the relevant modeline. This is a list of parameters that describe how a display should be driven at a specified resolution. See https://brightsign.atlassian.net/wiki/spaces/DOC/pages/420217686/Applying+a+Custom+Resolution#Modeline-Format to find out how to get a modeline in Linux or in BrightAuthor:connected.

  2. Add that modeline information to a BrightSign plugin. See https://brightsign.atlassian.net/wiki/spaces/DOC/pages/420217686/Applying+a+Custom+Resolution#Custom-Mode and the plugin example below for more information.

  3. Add the plugin to BrightAuthor:connected:

    1. Create a presentation in BA:connected with the correct Target Player, a single screen, and an Output Resolution and Frame Rate (in Layout Settings) that are similar the resolution you want.

    2. In the Layout tab, under Properties, adjust the zone Size to match your desired resolution, which must be less than 8K (see Image 2, below).

    3. Under Presentation Settings > Support Content, add the plugin that specifies the correct modeline.

    4. Add your content to the zone and publish your presentation.
