New equipment frustrations
Just bought this receiver last week to go with the TCL 75Q825 TV and Apple TV 4K units that I bought new the week before. The biggest ongoing issues have been getting the Dolby Vision feature on the Apple TV to work properly and dealing with intermittent audio-video lag from all sources. Every time I think I've got everything dialed in and working, I come back the next day and things are F-ed up again. Setup is as follows:
8K rated HDMI cable from Apple TV into Video 2 input on AVR, then 8K rated HDMI cable from ARC output on AVR to Video 2 input on TV. This was after multiple combinations of trying different inputs on both the AVR and the TV. Trying to connect the Apple TV directly to the TV and then outputting audio from the TV to the AVR through the TV's ARC HDMI output did not work.
I've reviewed the boards and think I have all the settings on the AVR and the TV where they are supposed to be. Two days ago I streamed Netflix through the Apple TV and got beautiful Dolby Vision video and synced audio. Turned it on last night having changed nothing and get blurry pixelated and laggy video. Switched over to watching a blu-ray through my PS4 and the video image was fine but still out of sync with the audio.
Any advice would be appreciated, love the potential of this equipment but really annoyed by the inability to just turn it on and have it work!
