In my case sure is overheating becouse from the time we put the atem1 directly under the blow of the air-conditioning it doesnt fail, if we forget turn on the air-conditioning the fail appear.
Note that is not only the hdmi multiview output fail, fails too the hdmi pgm output with the same fail, seems like a problem on the hdmi interface.

Hello:
First of all sorry for my english, I hope you untherstand me. I have the same problem than you and after I did the same things you did like change cables monitor, upgrede the Atem firmware to the latest one and the control software to 3.0 version I resolved the problem chaging the positiom on the rack of the Atem to the bottom of the rack where an air cooling machine blow directly to the Athem, them it is allways cold and works right, if you turn off the air and Atem turns warmer the problem returns. Seems very clear that the problem is the overheating! the real problem is that Atem have to work in a perfect cool embioramental that is not easy to get every where, I think that is a grave problem!!
I hope I help you.
