I had a couple of problems with my A7Rii to Atomos Shogun connection. 

 

The only things that I could suggest which solved my issue are as follows,

 

Buy a high end cable to connect from Micro USB to HDMI that is shorter than 3m. I bought mine from Maplin for rought £29.99 both work superbly.

 

Second option, check your firmware is up to date and compatible with the SSD cards you are shooting too, I have seen people have an issue with their connectivity because of using incompatible drives.

 

Let me know if either of these help.

When you say that you can't activate the 4k output, what happens? Does everything simply stop and go blank? Does it then restart? Have you tested this on a static & steady rig (to avoid any possibility of cable wobble) or is this an in-the-field experience? If 4k stops, can you record at other settings?

As Greg said above - avoid cheap cables and check compatible SSDs. (i wish Sony had taken the first part of that advice and used a full size hdmi rather than that stupid micro version).

Has also happened to me but I think the cold was a factor at the time (the A7s totally stopped working).

When it works the results are good... I use the 4k to help with reducing noise when downscaling to 1080 (results of my aurora filming are linked in the video showcase if you're interested).
