Pixel Mapping for LED banners and video walls

What is Pixel Mapping?

Pixel Mapping allows you to map digital content to physical LED banners or video walls. Instead of displaying content on a standard rectangular screen, you can map it to custom-shaped LED installations.

Use cases:

  • Stadium LED banners
  • Building facade LED displays
  • Curved video walls
  • Custom-shaped LED installations

Requirements

  • A device running Screenbird Player connected to your LED installation
  • The LED installation must be displayable via HDMI
  • Screenbird dashboard access to configure the mapping

Enable Pixel Mapping

  1. Go to Screens in the sidebar
  2. Click on the screen connected to your LED installation
  3. Go to the Settings tab
  4. Find Advanced settings
  5. Enable Pixel Mapping
  6. Click Save

Pixel Mapping is now enabled for this screen.

Configure the mapping

  1. Go to Screens and select your screen
  2. Go to Settings > Advanced > Pixel Mapping
  3. Click on Configure mapping
  4. The mapping editor will open

Mapping editor

  • Canvas size: Set the resolution of your LED installation (e.g., 8704 x 192 pixels for a wide banner)
  • Display resolution: Set the HDMI output resolution (e.g., 1920 x 1080)
  • Add regions: Define the areas of the canvas that should be displayed on the physical LED

Add a region

  1. Click Add region
  2. Set the coordinates:

- X: Position from the left (in pixels)

- Y: Position from the top (in pixels)

- Width: Width of the region (in pixels)

- Height: Height of the region (in pixels)

  1. Set the position on the display where this region should appear
  2. Click Add

You can add multiple regions to map different parts of your LED installation.

Configure content for Pixel Mapping

  1. Create or upload content as normal
  2. When assigning content to your LED screen, the content will be scaled to fit the mapped regions
  3. For best results:

- Use high-resolution content

- Test the mapping with test images or videos before deploying

- Adjust content colors and brightness for LED displays

Preview your mapping

Before deploying to production:

  1. Create a test content item (e.g., test pattern or color bars)
  2. Assign it to your screen
  3. View it on the physical LED installation
  4. Verify that the content is displayed in the correct regions
  5. Adjust the mapping if needed

Troubleshooting

Content is not displaying correctly

  • Check that Pixel Mapping is enabled
  • Verify the mapping configuration matches your LED installation
  • Check the HDMI cable and connections
  • Ensure the display resolution matches your LED installation

Regions are overlapping

  • Remove overlapping regions
  • Verify the coordinates of each region
  • Use the preview function to check the layout

Content appears distorted

  • Adjust the content resolution
  • Check the aspect ratio of your regions
  • Use content designed specifically for your LED dimensions

Tips

  • Document your mapping configuration for future reference
  • Test all content on the actual LED installation before deploying
  • Use test patterns to verify alignment
  • Keep the mapping documentation updated if you make changes
