I'm guessing you meant "60 Hz".
Those panels with rates beyond 60 use those extra frames to do some tricks such as motion smoothing which can result in unappealing effects. For now, I turn all off all video processing and sometimes a trick is to name the input "PC" or "Game" or find a Game "mode."
The problem I see with 60Hz models is that some Blu-Ray 24 Hz content will behave oddly. This is why they went to 120Hz so quickly as that is evenly divisible by 60 and 24.
As to vivid and such. Personal choices and folks are all over the map when it comes to "calibration."
Hi- I recently bought a Samsung 46- D630 lcd from best buy and was having judder problems even when playing movies. I am returning it for a Sony Bravia 46-450 lcd. It being a 60 hg set , will this help the problem? Also, does the cinema mode help make movies more film like? Samsung has a dynamic picture mode that I like and makes the picture look more bright and vivid. Does Sony have a similar mode . Thanks.
