A7III HDMI Out Issues

Recommended Posts

I've been using my A7III with the Elgato Cam Link 4K with no issues. HDMI Resolution was set to 2160p/1080p with 60p Output. Everything else in HDMI Settings was set to off and 4K Output Sel. was set to HDMI 24p or something. The image coming into OBS was basically 2160p24. 

This week I decided to buy the Blackmagic ATEM Mini and this is where my issues began. Plugging into the ATEM I got nothing, a black screen. Connected to the Cam Link and got a picture. Looking at the specs for the ATEM it'll only accept 1080p or lower. Changed the HDMI Resolution to 1080p with the Output set to either 24 or 60 with no luck. Tried connecting to a regular TV and the TV says no signal. It's almost like the camera won't output anything lower than 4k. 

I reset the camera with no luck. I haven't tried a different cable (Insignia cable).. But it's weird the cable would work with 4K but not regular old 1080p. I tried other sources on the ATEM and they're working perfectly fine.

Tried an A6300 and that worked just fine with the cable. Hooked it up to a 4K monitor and different resolutions work just fine. The A7III works just fine in 4K mode on the 4K monitor, but 1080p doesn’t work.

Anyone ever run into this issue before? Any ideas what could be going on? I’m at a complete loss as to what the issue might be

I'm having the same issue, I'm trying to find a sollution since two days but seems like nobody got the right answer or no answer at all... 

So my ATEM mini doesn't get the image from my Sony a7iii. No idea what I'm doing wrong... Did you already find the sollution?

No, I´m screen capturing OBS instead.
