Wired HDMI Screen Sharing with a capture device

Wired HDMI screen sharing is a one-plug method to share content from a laptop or mobile device to a Zoom Room. This method uses an HDMI-USB capture card peripheral connected to the Zoom Room to capture HDMI output from another device, such as a laptop. The capture card accepts HDMI on its input, and outputs to the Zoom Room using USB. The laptop OS can use mirror or extend display mode to output to the capture card. The Zoom Room can also accept audio, if supported by the capture card, which generally requires the laptop OS to be configured to output audio via its HDMI output. Alternatively, you can also use wireless direct sharing, share.zoom.us, or Airplay to share content from your laptop or mobile device to a Zoom Room.

Note: Annotation is not available when sharing content through HDMI. Please consider using direct sharing when annotation is needed.

Prerequisites for wired HDMI screen sharing with a capture device

• Magewell USB-HDMI, Magewell DVI Plus, Inogeni 4k2USB3* or Logitech Screen Share
  • Note: Other capture cards such as the Inogeni 4KXUSB3,  Share2U and Osprey Capture are not recognized as camera card peripherals - they are treated as USB camera sources only. 
• Magewell GEN1 firmware upgraded for 16:9 capture (default is 16:10)

• Zoom Rooms for Windows version 4.0 or higher

• Zoom Rooms for macOS version 4.0 or higher

  • Note: Zoom Rooms do not support the connection/use of more than one (1) USB-HDMI capture card peripheral at a time. If two or more capture cards are used in the same Zoom Room, they may act in an unpredictable manner, and the peripheral treated as a capture card may vary across system reboots. If you wish to have additional USB-HDMI peripherals presented as cameras (not a capture card), use an alternative device that is not one of the listed capture cards.

• (Optional) Kramer TP-580T and TP-580R for HDMI extension over Cat cabling
