I have all my devices, I.e. Directv receiver, Appletv, connected by hdmi to my Pioneer AVR. AVR by hdmi to Sony tv. Any video setting on my AVR has been left at default. HDMI Passthru is ON. Native Format is set to ON in the Directv Settings. With that said, if something on my tv screen looks cropped, especially on a Directv regular tv show, it’s because I have adjusted the tv picture using the Wide Mode button on the tv remote. That’s what I would check and keep that Denon AVR.
