Who says? Reviewers here rated the W9 above the F8000 (think it was Steve who said this) same over on HDTVtest.How come every1 always say that samsungs are the best tvs then? I think the 8000 received an update that reduces lag to around 20ms I believe.
Lag is low with no motion gubbins on, turn it on and it adds lag due to the way motion tech stuff works. Same with the Plasma screens.
Options on means more the tv has to process and do before displaying the image.
