I have a GH5 (not the S) and just bought a Ninja Inferno but am having the same issue with not being able to output to 4k 60p 10 bit or all 4K DCI modes. Genuine Atomos cable shows "No Input" but two generic ones work but stutter and chop the recording into ~3-4 second files.
Sounds like you have one of the older, HDMI 1.0 Atomos cables. The same happened to me — I didn't realise that there were two versions out there. The only Atomos cables rated for 50/60p are the current, $90 ones.
Also, regarding the GH5S stuttering issue in this thread, I am experiencing it even when recording 1080p at 29.97 to the Ninja Inferno. The same behaviour as described in previous posts — the occasional duplicated frame in place of the correct one — e.g. a sequence of four frames 1-2-3-4 is recorded as 1-2-2-4.
