Delay on LCD TV at DVinfo.net

Hello all

I use an LG LCD TV as a second monitor in Premiere CS5. However we've noticed there's a considerable visual delay in between the output on the TV and the output on the primary computer monitor.

The photo below demonstrates the problem. The same QuickTime movie has been dragged between the two monitors and is playing over the border between them. The movie is timecode playing at 60fps and you can see the left screen (the LCD) is on frame 97 whilst the primary monitor on the right is on frame 104 - a delay of 7 frames which is over 1/10th of a second!

The problem this causes is that the audio goes out of sync when you're watching the big TV. Does anyone know a way to DELAY the audio output; either from Premiere or from Windows?!?

thanks!

The simplest thing will be to use an external audio delay processor in the signal path once it leaves the computer.

Thanks for your reply Chris.

Where on earth would I get such a thing?!

This is one option that isn't too expensive.

I'm sure you could also add delay with an audio reverb/echo/delay filter. Simply drop the filter on the timeline, turn off the reverb and echo, and adjust the delay to suit your needs?

I think you're asking the wrong question.

Why is the second screen that far behind?

What's coming out of the secondary should be a carbon copy of what's coming out of the original, intact and on time. Why isn't it?

I don't know, do you?
