It was extremely bad when I had the PS3 connected to my receiver via optic and video to TV via HDMI. It got better (but still noticeable) when I config'd the PS3 to output sound to the TV via HDMI then optic from TV to receiver, but then I can't watch movies in surround. (the manual says input source must be TV to get surround sound #%!^#)
At this point, I'd be happy to even watch cable TV without the audio/video lag.
Any ideas? Is this a defective TV or is there something I can try besides buying a receiver with audio delay options?
I had some A/V sync issues with my 835U. My setup was PS3 -> Denon 1312 -> TV (all HDMI), then TV optical out -> Denon 1312. Using a calibration disk, I set my Denon to have an audio delay of 135ms, which worked well for blu-ray. When using built-in Netflix app, I set audio delay to 0ms, also worked pretty good. DVD content was never really out of sync much.
However, all this was too much of a hassle, so...
I returned the 1312 and got the 1712, which supports HDMI's Auto Lip Sync feature. Right away, I noticed a big difference. I didn't have to set the audio delay at all and A/V stayed in sync. The 1712 also supports ARC, so my setup was changed to:
PS3 -> Denon 1712 -> TV (HDMI)
No optical cable needed. The TV can send the audio back "upstream" to the Denon, using ARC (audio return channel). It was a little tricky getting the ARC to "turn on", so-to-speak, which I finally figured out to be:
Sharp needs AQUOS-link turned on. Then a menu option appears for Audio Return Channel, and you can turn it "On" (or "Auto", can't remember which). On the Denon, the ARC is only used when the input is set to "TV", and it doesn't appear that you can change this hard coded setting. I found that a little odd, since everything else is assignable, but I guess it doesn't matter. Just use the "TV" input when you want ARC, and it "turns on". The Sharp even displays a temporary message, something like, "AQUOS-link enabled." Now, I'm not even sure what AQUOS-link is, but I think it is simply their branding for support of HDMI 1.4 device communication features (devices can "talk" to each and give information like video processing delay, which is how the auto lip sync feature works, etc...)
