I didn't't know which forum to post this. I am currently redoing my whole system. The Sony 65 4k is in place and hope to get a new AVR either when the new ones come out or when some will ever be in stock again. My question is about potential lip synch issues with 4K disks. From what I understand the delay in the AVR can be set that will allow the Sony Video to catch up. Is this a one time thing to dial in? Can the whole issue be avoided by connecting the two with an earc assuming all the nightmares I hear about that are resolved?
