a7III – Sony – How To – Changing HDMI Resolution
My camera is shooting in 4K, and I can see the footage on my FOCUS Bolt 500 TX. The footage does not appear on my FOCUS 7 RX unit.
The Teradek Bolt components cannot handle 4K video. You will need to select a 1080p resolution on your camera’s HDMI output (you can still record in 4K). To change this setting, on your camera go to MENU → (Setup) → [HDMI Settings] → [HDMI Resolution] → and select 1080p. You can visit this page in the Sony manual for more information about this setting:
