I don't know what could be causing the lag.
Unfortunately, I'm at a bit of a disadvantage, as I don't understand the terms "stage" and "extract stage" means.
Which country is your product sold in?
--HDTech
Samsung 40 inch HDTV, full 1080p, 1920x1080, model LE40A558, and it is in series 5.
Connecting AV having no lag on different non-hd tv,but connecting ps3 by hdmi 1.3b do have minor and major input lag. For example, some stage are smooths and less minor lag, and few extract stage are always have major lag all time. Hdmi is connected in hdmi number 2, i got some socket plugged to pc. It is not turned on.
Do you know how to optimize as smooth as possible?
I'm a bit not okay with the level of lag.
