Roy,
I have a question. Is the Actiontec device you mention in this YouTube video needed in addition to the device you provided a link for in your original email response? (That is,
https://www.screenbeam.com/products/screenbeam-mini2 )
If both devices are needed to support third monitor display, can you please provide a link for the device you mention in this YouTube video?
Thanks in advance,
Gwen
