I have an LG OLED 65E6V television and have just paired it with a Denon AVR-X2300W receiver. I connected the Receiver and TV as instructed via HDMI (ARC). I also connected an Optical link from the TV to the Receiver's Digital Audio IN 1 TVAUDIO (not sure whether I was supposed to do this but the cable was already coming from the rear of TV from a previous set up!). I then followed the Denon’s ONSCREEN SETUP ASST. I connected my Humax (OSN) satellite set top box with no problems, connecting it via HDMI to the CAB/SAT HDMI 4K IN port on the Receiver. I set up my Bluray Player as instructed via HDMI to BLURAY port on Receiver. so far, so good but then I hit problems - I tried to connect my 4K Bein satellite set top box and Wii - how do I connect these? I thought that there may be a problem with the Bein box so I removed the Humax (OSN) box from the system and connected the 4K Bein box via the same connections - still no picture. However I can get audio and video if I connect Bein direct to my LG TV’s HDMI IN socket!! Then I tried to connect the Wii via the GAME setup and can only get audio. Obviously I am doing something wrong but what is it? All my HDMI cables are new and HDMI2.
