LED Media Commander is implemented in a different way than the traditional server/client model.
Instead of delivering a Userful network stream to a wall, it uses the GPU's built-in video output to send perfectly synchronized content directly to the LED controllers. This method has the advantage of leveraging Nvidia Mosaic technology to achieve perfect synchronization on a multi-controller LED wall, as well as providing a Userful content delivery method and native source ingestion.
Display outputs on the Nvidia GPU (Quadro RTX 5000 or above is required for multiple video-outs, or multiple controllers, or more than one 4K output) are fed directly to the LED controllers. Note that the controllers must be calibrated ahead of time - consult your partner to ensure this process is completed.
In the Control Center of your Userful server, you will see a single onboard display . This represents the combined video outputs on the Nvidia GPU. We do not need to associate or connect any other displays or devices.
To configure our LED canvas, we now use the Media Commander button in the sidebar:
This will open the Media Commander Tool that will allow you to configure your canvas to any shape or size, using 1 to 4 outputs from the GPU.
Set each output's resolution as desired. The list of displays and resolutions should automatically populate. If not, re-seat the connections and click Refresh.
Adjusting the Vertical or Horizontal Padding will add one line of pixels at a time to the border between LED panels. This applies regardless of pixel pitch.
When the calibrated setup matches your LED wall, click Save.
Finally, map the display into a 1x1 Video Wall
This will allow Userful to “break” the traditional X boundaries and scale content smoothly.
Map the Zone to a Source, start the zone, and now we have perfect content playing.
Once proper synchronization is established, map the onboard display to any Source, including Command & Control, and you will be ready to deliver content!
