Macbook Pro, late 2016 (Radeon 455 model).
TV: Samsung UN40KU6270 40-in. Smart 4K UHD LED TV
Cables (tried two different 4K @ 60hz certified ones)….
Still says 4K @ 30hz in about this mac>system report > graphics/displays
Help!
Setups with TV’s normally work best by making a custom resolution for 3840x2160p at 60Hz with timing standard set to CVT-Redecued Blanking (RB). On MAc OSx you will need aprogram like SwitchResX to be able to do that Timing Setting.
