You can connect the camera to a TV with a commercially available HDMI cable to view images and movies captured with the camera on the TV.
When using a USB cable, the camera cannot perform HDMI output to the TV.
To play back movies that are recorded with [2160/30p] (4K UHD) or [2160/25p] (4K UHD) in 4K UHD image quality, use a television and HDMI cable that are compatible with 4K. Also, select the setup menu [HDMI] [Clean HDMI output] [Off].
