Got a tech question for Sound & Vision? Email us at AskSandV@gmail.com Q I have been a big fan of S&V for many years and it was the first place I checked to find out the best way to set up my new Apple TV 4K (third generation). Unfortunately, it seems some of the information is dated or conflicting and related to earlier generations of Apple TV. I have a Denon AVR-S750H surround receiver and an LG OLED77CX 4K TV.
