LED Media Commander Setup
LED Media Commander is an efficient content streaming solution as it uses the GPU's built-in video output to send perfectly synchronized content directly to the LED controllers. It differs in functionality as it does not use Userful's network to stream content to the video wall and in implementation as it does not follow the traditional client/server model.
It leverages Nvidia Mosaic technology to achieve perfect synchronization on a multi-controller LED wall and provides native source ingestion.
Content flows through Userful directly into the controller
Display outputs on the Nvidia GPU are fed directly to the LED controllers. GPUs like Quadro RTX 5000 or above are required for multiple video outputs, multiple controllers, or more than one 4K output.
Userful server connected to two Novastar MCTRL 4K LED controllers
Contact your Userful consultants to ensure that the controllers must be calibrated ahead of time.
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.

Steps to Configure the LED Canvas

  • Click on 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. Note that the Output values may not exactly match the numbers on the GPU itself. Some trial and error may be necessary to determine the correct output.
If you do not see this button in the Mapping section of UCC, contact your Userful Account Manager or Sales Engineer.
  • Set each output's resolution as desired. The list of displays and resolutions should automatically populate. If not, re-seat the connections and click on the Refresh option.
  • Adjust the Vertical and Horizontal padding. This adds one line of pixels at a time to the border between the LED panels. This applies regardless of pixel pitch.
  • When the calibrated setup matches your LED wall, click on the Save option.
  • Finally, map the display into a 1x1 Video Wall. This will allow Userful to break the traditional X boundaries and scale content smoothly.
The above example is for a specific use case only. Please consult with a Userful Sales Engineer if you are experiencing difficulties deploying LED Media Commander.
  • Once proper synchronization is established, map the onboard display to any source, including the Command & Control, and you will be ready to deliver content!
