Why is the picture cropped on my TV?
The television's overscan or zoom mode may be enabled; select screen fit or original aspect ratio.

A practical check
Use a known 16:9 video on the same HDMI input and inspect the TV’s input fit setting. If the test item fits and only one channel crops, compare the player’s aspect setting for that channel.
