A:AnswerFor 1080p Samsung sets, "Motion Rate" = Refresh Rate. For all others (i.e., 4k, 8k sets), Motion Rate = double the actual refresh rate. So for 4k & 8k sets, a "Motion Rate" of 120 means the LCD has a native refresh rate of 60 Hz
A:AnswerTrying to get same info. Went to Samsung site and measured the full of tv on the display with a tape measure then figured out the ratio of the size on the monitor to the specified width. Then measured width between outer edges of stands again with the tape measure and multiplied by the ratio calculated previously. It came out to 52.6 inches. Will I swear by it, no. But it should be close. Make it 55" for safety.
