I have the SAMSUNG UN55C6300 LED TV, It's suppose to be a 120hz TV. I am having no positive results in getting the TV to support a 1920 x 1080P @ 120Hz Resoloution. I am using a nVidia 9600GTwhich is suppose to support 120hz. I am using a DVI-D Dual Link to HDMI cable. Can Anyhone shed some light and tell me if it's my TV, GPU or both or if I need forceware or anything I might be missing.

PS it does support 1920x1080P @ 60hz

More about 120hz
  1. I do not know if this will help,,but the cable from the card to a 120hz monitor is not the same as a standard dvi cable the 120hz monitor uses all the pins whereas the 60hz uses a standard connection, ie,,only half the pins...:)
  2. 120Hz HDTV (and this applies to 240Hz as well) operates differently from 120Hz PC monitors. The "120Hz" refers to internal video processing to make movies look better and play back more smoothly. This internal processing creates input lag 'cause the TV electronics receives the signal, then processes it, then displays it.

    It is suggested that when you play games in "Game Mode" which switches the HDTV to 60Hz mode so that it does not do any video processing, thus create no additional input lag. All HDTVs only accept 60Hz inputs.

    If you want to "play games at 120Hz", then buy a 120Hz PC monitor.
