What is the High Frequency Rate of the Samsung QE49Q6FNA?
The refresh rate (also known as the high frequency rate) is the number of times that the image on the screen is refreshed per second. It affects how smoothly motion on the screen appears.
Action will appear smoother on TVs with a higher frequency rate: a TV with a high frequency rate of 30Hz refreshes the image on the screen once every 30 times every second. However a TV with a high frequency rate of 60Hz would refresh the image on the screen 60 times every second which means that action scenes would appear smoother.
