LM860v ->ARC HMDI ->bluray 3d player. Only when watching 3d blurays, there are sync issues for about -300ms, all other media syncs correct. Now I have enabled AV sync with bypass on the 860v, but to no result. Any idea where this comes from? Both sets are firmware upto date. But when the sound is comming from the TV, also no sync issues.
Thanks for the complement, but wait a minute, now I'm confused. 3D could well by itself cause more lag since it's doing more processing----but your cable configuration I no longer understand. I thought you were saying something else.
Let's go over this from the beginning:
If you are doing this:
BR ----(HDMI)---> LM860V
How is the (lagged) sound getting to the receiver? The ARC can't land on a blu-ray and go anywhere.
If you're are doing this:
BR ---(HDMI)---> Receiver[config'd for ARC] ---(HDMI/ARC)---> TV
Then the TV is supposedly back channeling the sound to the receiver. The BR should not be performing any lag duties (ms delay) at all.
The sound would travel this route:
BR ---> Receiver [straight through the receiver and not
its speakers] ---> TV ---> Receiver [and to the speakers]
By the way, your receiver needs to be using the ARC configured HDMI ports so it knows to pass it through on the first pass.Edited by tgm1024 - 3/19/13 at 12:30pm
