Has anyone here attempted using the HDMI output on their a7iv? I bought one to use both for photo and for video, and for video I was planning on using my ninja v that I use with my a7siii. When I plugged into the ninja the camera immediately overheated, within 15 min. No recording, just sitting idle outputting hdmi. I've tested with every resolution, frame rate, af setting, and no change. Even with 1080p it heats up quickly, and even with auto-shutoff set to high. If I don't hit record internally it will last over an hour outputting, but if I record a single minute of footage it immediately overheats. This is my second a7iv body, I exchanged for a new one because of this exact issue, and the new one is identical. And this is middle of winter. If I ever try to use it during the summer or in a warmer room it will be unusable even for just external output.
