i bought this reciever a few years ago because it said 4k pass-through. so i hooked up my directv 4k to it and back out to my LG OLED 4k and i get an error on my screen saying this tv doesnt support 4k. so i plugged my directv hdmi right into the tv and it works fine i'm not sure if i have something on screen no setup right or if i just read the specs wrong. i would hate to have to buy another reciever just to get it to pass through right. if anybody has some questions or answers please let me know <3
