I'd like to confirm configuration of my TV/AVR system because currently I have a lip sync problem ever since replacing my old HDTV. I've read that the way you're supposed to connect a Cable box to an HDTV and AVR is 1) use an HDMI cable from cable box to TV and then 2) run an optical cable out from TV to AVR to get my surround sound. Would this solve my lip sync issue?
If in future I get a newer AVR that accepts HDMI inputs (my Denon 1706 is about 6 years old), couldn't I run the HDMI from cable box to AVR, then run an HDMI out of AVR to TV (not using any optical cable from TV to AVR)? Sound then should match what is being displayed I would think since the AVR is sending the sound and video at the same time. My new TV is 3D and although I didn't necessarily buy it for that, I may as well get what I need now. This way when I get a new 3D DVD player, I can connect it to AVR using HDMI still using the same HDMI out to TV.
I've been told that most AVR's now can pass 3D content through to TV. Whether from cable broadcast, DVD player etc.
Currenty I have a lip sync issue on certain TV channels. My guess is because (currently) my sound comes out of cable box to receiver using SPDIF, and an HDMI cable is going from cable box to TV. Currently no optical being used from TV to AVR so the sound plays slightly before video on some channels. Lip sync was always spot on with old HDTV but I guess these new ones are different.
Thanks for any help or confirmation.
