I have an LG OLED 65E6V television connected to a DENON AVR-X2300W cinema amp. My source equipment are a 4K Bein Satellite decoder, HD Humax OSN Satellite decoder and a PANASONIC DMP-UB900 Bluray player. Each piece of equipment is connected using HDMI2 cables. I have the TV connected to the AVR using the ARC HDMI channel. QUESTIONS - 1. which part of my setup do i use to adjust the picture? and 2. what picture settings should I set the others to?
