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

Hello,
I am running the ATEM 3.2 software on the host PC.
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.
The resolution is 1920x1080 i need to find a laptop that match the fps ?
I know that the laptos work at 60fps, but the camera we own works at 50 fps
What can i do , Please Advice.

Best Regards,

Lefteris

1) Why are you using such an old version of the ATEM software/firmware? We are now at 4.2

2) Have you tried matching the frame rate on the laptop adapters advanced settings?
