I looked up your avr and it includes upscaling processing. Does it offer the option to turn it off? Some avrs do offer the option but still do some processing though. Since the Marantz doesn't do 4k, your best option is to connect everything directly to the tv and let it do the upscaling.Thanks for the reply. I swear it does look better than going thru the receiver but you know how that goes. In any case, will see if this has anything to do with the motion and soap opera effect that seems to show up out of nowhere when I turn on the TV or switch from an app to TV. Doesn't do it all the time, chatted with Sony and they were no help.
