Atem extreme ISO HDMI Port 1

I have an unusual issue going on with my Atem Extreme ISO where only my portable monitors work I can't plug HDMI port 1 into anything else and get a signal.
Things I've done
Hard reset hold mic on and power cycle
clear state
reinstall software
tried other monitors
changed settings in atem settings for monitor resolution and frame rate
and it only works with my MSI Portable monitor(MAG161V)
and the multview is on AOC portable touchscreen 16t2 in HDMI port 1

feels like a frame rate issue but other monitors that are within the range dont work

I don’t understand what you’re trying to do, plugin a monitor into input 1?????

Not all PC monitors are able to display 25 or 30Hz source.

Set your ATEM to 1080p50 or 1080p60 and see whether that works.

The AOC monitor specifies vertical frequency from 48 to 75, thus not able to go under 48fps.

Perhaps you could tell us what devices DON'T work, then we may be able to help

I will make a youtube video and post the link thanks for the response folks
appreciate the help
