HDMI port on bottom of monitor

I tried hooking up the HDMI port on the bottom of the montor to aid in training my class, but it does not seem to be functional. Should it work?

From the MDI line you can use the command “ADMIN DISPLAY” to access the display options.
From there you can check the box next to “same image on all monitors” and share your screen with your students.

@Roy_VanGemert which machine are you using and where are you plugging in the HDMI cable? I thought more about this and want to clarify that the comment I made is relative to the xsTech computer or the Operator Console.

Thanks, yes I am using the router, trying to teach students on the overhead.
