“What’s the difference in the refresh rate between the S515 and S517?”

1-3 of 3 Answers

• There is no difference. The 55s515 and 55s517 are the same TV except for the remote control. The 515 uses infrared so it must be pointed towards the infrared detector in the center of the lower bezel. The 517 remote uses Radio Frequency and so it can be pointed in any direction to function. Because the remote for the 517 uses RF it also has a 3.5mm headphone jack built into the remote. This would not be practical with a remote that must be pointed at or near a specific spot on the TV.

• The refresh rate is 60hz. Im sick and tired of these tv manufacturers trying to trick people into thinking they are buying a 120hz panel.
