Video processing and audio processing are different settings in an avr. I'm not talking about the audio, but what you set your avr to do with video signal (let it go thru without any processing such as upscaling or resolution or format changes....).
However, now that I look through your manual you do not seem to have any such video processing in your avr, so never mind

. Not a bad idea to save money and remove the extra video processing I suppose; mostly I bypass the avr's video processing anyways. The only video processing I saw evident in your manual is that it can take a legacy input, component video, and output that via hdmi.
Curious about the HDMI CEC being off if you're using ARC...on my avrs I have to enable CEC to work with ARC. In your manual it says if you've answered "yes" to ARC Setup (p.157 in the online manual) then HDMI CEC is automatically enabled.
