Hello. What settings should I apply for best picture and sound quality? I have Zidoo X9s, Samsung 55KS8000 - both 4k UHD. And Denon AVR-2312 - without 4K. I'm watching a movie and TV show from my NAS. Mostly HD (1080) - 90%. X9s connected to TV (4k video). Denon connected to TV (SAT player) TV connected to Denon with Toslink (Home Theatre) In this setup I'm loosing HD Audio. Right? What video mode should I setup: Auto or 3840 x 2160 x 60 or 1920 x 1080 x 24 I need your help. Thanks.
