I’ve got a Bravia 8ii. My Apple TV is set to 4K SDR 60 Hz and Match Dynamic Range is on and allowing it to auto-switch to HDR and Dolby Vision. Does Match Frame Rate also need to be on with this TV? I’ve been searching, but some places say yes and others say no.

I’ve had the TV for a few months and the only problem I’ve had is audio on a couple HBO Euphoria episodes got out of sync last weekend. I deleted and reinstalled the HBO app and rebooted the TV and it hasn’t happened since, but I need to test it more. One source said that match frame rate can cause audio sync issues.

I have a Sony STR DH590 5.1. I want to upgrade to a Denon AVR-X1700H 7.2.

Would I be able to get Atmos sound by adding 2 wireless speakers to my existing speaker setup? And if so, could the two new wireless speakers be used for the rear speakers, making my 2 existing ceiling height wired speakers the Atmos speakers?

If that would work, do you have any recommendations for two wireless speakers?

Thanks.
