About:
Wired HDMI screen sharing is a one-plug method to share content from a laptop or mobile device to a Zoom Room. This uses an HDMI capture card to communicate between local device content with Zoom or a Zoom Room.
There are other methods to share content from your laptop or mobile device to a Zoom Room:
- Wireless direct sharing via proximity or sharing code
- Wireless sharing via share.zoom.us
- Wireless Airplay mirroring on MacOS or IOS
Pre-requisites:
- Purchase a Magewell USB-HDMI, Magewell DVI Plus, Inogeni 4k2USB3 or Logitech Screen Share
- Other capture cards (Inogeni Share2U, Osprey Capture) are camera source only
- Upgrade the Magewell GEN1 firmware for 16:9 capture (default is 16:10)
- Zoom Rooms for Mac, PC/PC Touch version 4.0x and higher
- If you need 2 capture cards, they have to be 2 different brands (e.g. Magewell + Logitech)
- [Optional] Kramer TP-580T and TP-580R for HDMI extension over Cat cabling
