      Hello, when trying to cast to the Promethean board using ActivCast, it will only show a black screen. Here are the steps I have tried to fix this:

      1. On what operating system are you mirroring from? (Windows, Android, iOS, or via Chrome Extension?)

      Tested on Chromebook and iMac (10.15) using ActivCast Sender Chrome Extension (Chrome version 92). Both just show black screen.

      2. What is the Firmware version of your ActivConnect?

      3. When connecting the mirroring device and the ActivConnect to a wifi hotspot, does the issue persist?



      I have also verified that all of the URLs are allowed in our firewall and ports are open per this page:

      Any help with this issue would be greatly appreciated.

      Hello Michael,

      Thank you for your post.

      Are you using an ActivConnect-G or an OPS-G with ActivCast? In addition to this, kindly update the ActivConnect-G or OPS-G to the latest software version using the links provided below, and then re-test.


      Lastly, please provide us with the Chrome OS version that you have tested this on.

      We look forward to assisting you further in this matter.

      Kind regards,
