I have the 40" Samsung and I prefer to keep the Auto Motion Plus 120Hz setting turned off. Lately, every 15-30 minutes or so, the Auto Motion Plus setting automatically turns on to the "standard" setting.
The last time this occurred, I updated the software on the computer, but there is no update at this time. How do I keep the auto motion plus from turning back on?
