A few days ago I bought the TV 42G10, my surprise was in the operation of the IFC, nothing to do with the operation of the IFC panasonic PZ85. In the PZ85 when selected IFC ON , the movements were smooth, even roll the end credits of the films were smooth. In the G10 to enable or disable the IFC, the feeling is the same. I do not see any change.
i think.......need a firmware update for the G10? Why the IFC showed the PZ85 and the G10 is not as if there?
