Buying AppleTV 4K right now and I have Visio 4K tv (cheap D series) already but a years-old LG BluRay home theater setup (blue ray home theater setup with subwoofer and 5 other speakers). What cabling and how do I connect? I obviously can’t run the 4K video through my Blu-ray and then to TV like I did with my old 3G AppleTV. Do I run a good HDMI straight to TV and then ...?
