LipSync issues

by NJohnson / February 23, 2004 3:23 AM PST

I am interested in whether or not many of you see significant lip-sync problems in broadcast TV and even when watching DVD's. I have noticed significant delays in the video that allow the audio to lead which is a very unnatural and noticeable condition. I hooked up some audio delay units and have played with it a little to correct for the delay which I expected was primarily a fixed delay caused by my scan converter and LCD monitor but I have found a more than 60 milli second variation over the course of a day which seems to indicate that the broadcast signal (actually mine is Time Warner cable) itself arrives out of sync by different amounts during the day. Is anyone else experiencing this? If so, are you on cable or over the air broadcast? I have noticed this problem on a 42" plasma as well but haven't experimented with delaying the audio on it yet. I don't believe it delays the video as much as my LCD set-up (about 80MS). If anyone is aware of any devives or equipment designed to correct this problem I would apprecaite knowing about it. Thanks

"Is anyone else experiencing this?"


"If so, are you on cable or over the air broadcast?"


"LCD set-up (about 80MS)."

Wait a second, is this a PC? Or other?

"If anyone is aware of any devives or equipment designed to correct this problem I would apprecaite knowing about it."

Unless you are on a normal TV, the broadcasters don't care. If you are on a normal TV, then you call your CableCo and keep at it until they fix it or write you off.

From what I hear, "it's the money."

I notice I have this problem when the TV is set to surround sound but I don't have surround sound so I just set it to stereo. This may not be the same problem as yours.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
