Hello , on 8.3 version still exist problem with HDMI CEC , when switching on Vu+ Ultimo 4k , HDMI input in Denon AVR should be changed automatically into proper CBL/SAT input , like in others gears like- Bluray player , media player. On Sony oled TV signal CEC is sending properly and tv input are switch for tuner sat. With AVR this never worked !!!! Time to fix this !!!! Thanks.
