Supported Multi-Output Devices

Multi-output devices are devices that can display content across multiple independent outputs. Hardware capabilities and behavior vary by device type and model.

This article addresses which multi-output devices are currently supported and outlines hardware-specific considerations for each supported device type. For information about configuring and managing multi-output devices in the Videri Platform, see Managing Multi-Output Devices.

Supported Hardware

As of September 2026, multi-output functionality is supported on the following hardware:

Display Considerations and Limitations

As of September 2026, the following limitations are present for multi-output devices:

SparkBridge+ Multi-Output Support

1. The following video outputs are supported:
   1. HDMI
   2. DisplayPort
   3. DisplayPort Alt Mode via USB-C
2. Supported SparkBridge+ models can send video to a maximum of two independent displays. If a third video output is connected, the third display automatically mirrors the content shown on the second designated output. Because the third output is not independently addressable, it does not appear as a separate output in the Videri Platform.
3. Some display-management functionality available for the primary display is not supported for secondary displays. The following functions cannot be independently configured for a secondary display:
   1. Color settings
   2. CEC
   3. Custom resolution
   4. Orientation: As of September 2026, secondary displays are locked to landscape orientation.

AllSee Multi-Output Support

1. Supported AllSee devices use their internal system-on-chip (SoC) to provide content to multiple displays.
2. When using Video-In, the incoming video source is shown only on the primary display. Secondary displays continue to show content generated by the device's internal SoC.
