ATEM 1 M/E doesn't laptop as HDMI source

I setup an ATEM 1 M/E as a demo system in my shop. I am using the very same laptop that normally connects to my ATEM Television Studio. My Television Studio sees the output of my laptop as an HDMI source. When I connect the same laptop to any of the four HDMI inputs on the 1 M/E the laptop isn't seen.

I have connected the HDMI output from my TriCaster 855 into the 1 M/E and the 1 M/E sees the HDMI output from my TriCaster 855.

I connected a second computer with an HDMI output and my ATEM 1 M/E didn't see the computer as an HDMI input.

Do I have a 1 M/E with flaky HDMI inputs or is this something else.

I am running the ATEM 3.2 software on the host PC . . . .

Remember, my Television Studio sees the HDMI output of my laptop using the same host computer driving the 1 M/E.
