The 2017 43" model also has a 60 Hz panel. Where did you see that the 2017 model has a 120 Hz panel? We never reviewed the 2017 model, so we donโt know for sure what differences there are between them.
The big difference between 2017 and 2018 is that in 2018, the power and A/V signal are both carried over the OneConnect cable, versus a separate standard power cable going to the TV panel for the 2017 models.
