I'm sorry to hear that you're having a problem with some of the playback.
Try turning the AutoMotion plus to "Smooth" or "OFF". It may be some of the additional picture processing that is causing the "pause/hyper" symptom you're describing.
60hz on the INFO bar notes the incoming signal - most incoming signals will be 60Hz. Since the panel is a 120Hz panel, it will upconvert and always show at 120Hz, regardless of the signal going into the TV. Very few devices on the market send a native 120Hz signal.
Does that help?
Ok, so 1) im new here, and 2) we just bought a samsung c6400 from costco. It looks great in the store, but i cant say the same for our house.
We have a TWC DVR connected via HDMI and a X-Box 360 with HDMI. On both the picture ok, but it pauses, then becomes hyper. The pause is only like 3ms but its noticeable. When we turn on the TV, it says the resolution, then 60Hz?? Its supposed to be 120!!
Im guessing thats the problem, but dont know how to change the refresh rate. HELP!!!!!!!!!!!!
