What is the max recording time on A7sii, using an external monitor?

What are the max. length videos you can record on an A7sii, using an external monitor via HDMI? (I don't think I'm interested in 4K, so 1920x1080.)

I ask because Nikon recommends that the camera I currently use, a d810, only records in Live View for 10 minutes at the time, in order to protect the circuit board. And that's not long enough for me.

Which means I need a new camera. And some time ago I looked at the A7sii and thought it looked nice (and I would be able use my Nikon and Zeiss-Nikon glass, which is a must).

But I want to be sure that I can record at least half an hour video -- while using an external monitor -- without overheating issues.

So, what are your experiences?

Should be pretty much unlimited in HD to an external recorder...

I'm not going to use an external recorder, just an external monitor...

EDIT: But it got me thinking: What if I did use an external recorder with my d810? So I asked Atomos, but their recorders unfortunately get the signal from the Nikon's Live View, which means the d810 is limited to 10 minutes of monitored recording, no matter how you slice it.

So I'm still very interested in the max length of monitored recording in 1080p on an A7Sii...
