The television's panel is a 60Hz television.

The 120 Clear Motion Rate is a standard used to measure the performance of the panel. It does not have a 120Hz panel, and the Auto Motion Plus feature, which is available only on 120Hz panels.

You might check the settings on your Blu-Ray player if you're getting judder. In some cases, the resolution or Hz rating output on the player might correct some of the effects you're seeing.

If that doesn't help, you might try calling for some troubleshooting options at 800-SAMSUNG with someone who can walk you through the settings while you're on the phone.
