Just bought the apple tv 4,my first apple product, really love the quality but having trouble with the av not matching, set up as instructions by professional calibrators on the utube site i.e. Apple 4k tvs lip sync audio out of sync a quick google search suggests this is a common problem.
lip sync battle is already a huge viral sensation.
Watched the first harry potter film last night and the lip sync was bad at first, it almost caught up after a few minutes but was never perfect in the film. However, i am having lip sync issues with most files. I've been an att tv customers since direct tv now, when the entire service was in beta. But if i adjust a/v sync in receiver for dolby vision content then i have to adjust it again for sdr and hdr content and so on.
