picture lag !! please help :(

[admin_exported]

please help peeps......

after many years of nagging, I finally convinced my wife that we should get a better TV/home cinema system..

so ... bought a Samsung LE40C654 (5 stars on here) to go with our Sony DVD/HDD player/burner. We then binned the old philips surround sound system and I got a Sony BDV-E370 (also 5 stars on here) ...Blu Ray player/surround sound system.

Excitedly I set it up tonight .... (using a 15.2GB HDMI cable) from the Blu-ray to the TV..... picture is great ..... BUT ....... the sound is a split second to FAST and so out of sync with the blu-ray film

jumping through the film, the sound doesn't even appear to be out of sync by the same amount, being more obvious at times than others....

Checked by turning the speakers off on the blu-ray system (in the system menu) and the sound through the TV is perfectly in sync with the film....

please help as I am gutted

many thanks

Take a look at your TV setup options and try turning of any additional image processing jigger pokery. I found with my panasonic that it gave me the same problem you describe. I think the image processing means the TV has to think a little more before it displays the image and when the sounds is also processed through the TV all is well, when you route the sound through an amp you get the synch issue.

oh crickey - that won't be easy .... it seems to have so many menus within menus and I have no idea what is all does (and most of it is not mentioned in the manual) ...eeek

is it too much to ask for a brand new 1080p TV to play a blu-ray and have the sound come out at the right time?!

Might be worth a full power down of both tv and bd for a half minute and then reboot.

ok tried to turn off everything within the TV that I researched that might be an issue... and the reboot idea ... still noticeably out

so ..... grabbed my DVD/HDD's HDMI cable (just a normal DVD standard one from comet) and tried that instead of the 15 GBps one ... and its miles better - if not spot on..... BUT the picture quality is not as good....

could the better cable be moving the sound too quickly?! seems a bit odd this .... ideas peeps?

 

[grdunn123]

It may be a faulty cable....worth trying a good budget cable such as That Cable for about a fiver if I remember rightly

Bergy,

so you're saying that the sound when you listen through the surround system is ahead of the picture, but when you listen to the sound through the TV it is almost in sync ? If you have the sound on both the TV and the surround speakers turned up do you get an echo effect ? If the TV looks correct and you can listen to both TV and surround at the same time, find the audio delay menu in your surround system and delay the audio one notch at a time (usually 10 msec increments) until the echo vanishes.

The cable can't make any difference as the audio/video signal is a single datastream with the audio embedded into the signal together with the video. The delays come from the processing in your TV or Surround box - it's far quicker to decode and process an audio stream (even a DTS or Dolby HD full surround uncompressed one) than it is an HD video stream, especially if you have lots of processing modes active on your TV.

Try the above and see if it helps.

I thought HDMI had a separate audio stream?

The tv has approx 45ms of input lag. So hopefully your bluray player has the option of accounting for that

It could also 'vary' if the settings are wrong on your tv - Theres usually various 'film mode' settings on tvs that most people dont have a clue what they do. If the incorrect one is selected for your source then youll sometimes get variable lip sync issues (On top of the 45ms above)

ok - fed up with now

turned off/ altered every setting I can find on the TV, reducing the processing etc ..... found the bit where i could alter the sync on the sound (although this was related to something called SPDIF - or something like that) so not sure if it related to the blu ray ... nothing worked

then found the same area on the blu-ray player which allowed 0-300ms sync changes (put it on the max of 300ms) ..... still no better.....

had hoped to check out the idea suggested above about the TV and surround sound speakers being out of sync and thus an echo effect being heard, but the sound is defo coming out of the TV AND the surround at the same time and I can't turn one up without the other. Weirdly the two systems seem to have linked (even though one is sony and the other samsung) as the two remotes will BOTH alter the combined TV/surround sound volume.

totally baffled now and beginning to wish I hadn't bothered with the blu-ray stuff

can anyone think of why or how I might test certain things to see if I can narrow down anything?

thanks chaps

No wonder it didnt work. Set it at 50ms

sorry - didn't explain that well .... went from 0ms (which is what is was on by default) up to 300 in 100 steps ..... i take it I should try it in smaller steps yes??

to see if it was a samsung/sony issue I got a samsung HT-C5500 yesterday and plugged that in ... PERFECT sound sync straight away with no need to change anything !

I would keep it instead of the sony, but the picture quality on the samsung is nowhere near as stable as the sony. The samsung has loads of 'flickering' on shots where there is grass; chain mail; straw roofs ... which is really noticable and annoying when we watched robin hood as a trial ....

really appreciate any further comments/help ......

 

[aliEnRIK]

I dont know how to make this any more clear

Set to 50ms
