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."

Good luck,
