I’m trying to get a 60Hz connection between my Mid 2014 Mac Book Pro and a Samsung UE40S9 but it only seems to do 24Hz. I’ve included links to the parts I’m using below. I’ve gone through the menus on the TV turned off every sports or motion feature and enabled 4:4:4 UHD. First question is, have I bought the wrong connectors? Secondly what should I be looking for in the TV menu or on the Mac to get 60Hz.
