This is difficult to answer because the majority of Sonos Arc users don’t experience any lip sync issues using a variety of different TVs. Most of the time, lip sync issues are more related to a user’s specific setup, settings, or media device rather than a specific TV model. For example: Sky Q boxes are known to have lip sync problems.

But if I had to choose a specific TV brand to steer you away from, I would say Samsung, especially the Samsung Frame. I’m sure many Samsung/Arc owners would probably disagree though.

I’m using my Arc + Sub + 2xOnes with Sony AG9 and I have no lipsync problem … sound is perfect out of the box :-)

I had a LG E7 before and had a bit of lipsync
