I tried to use my new A7R4 as web-camera, but it prompted overheating warning in less than 30 min and did shut down.
I was using the camera’s usb-c connection to MacBook Pro usb-c and same time the hdmi connection to freeworld t7 field monitor hdmi.
My old A7R3 had newer overheating problem while using the micro-hdmi to field monitor and taking the hdmi signal from field monitor to MacBook Pro usb-c via elgato 4K capture card.
