I'm trying to hookup my mid 2014 MacBook Pro(GT 750m) to my 4k samsung TV.
The TV itself has HDMI 2.0 support(KU6300) and I know my MacBook Pro doesn't support HDMI 2.0, and only HDMI 1.4. So I'd need to use the mini display port to get UHD@60hz. So I bought a cable that does mini display port to HDMI (not sure on the number for the HDMI).
When I run windows, I can set the resolution to 3840x2160 at 60hz through the Nvidia drivers, I don't have to create a custom profile or anything, 60hz is there as an option. But when I try to use MacOS sierra, I can only get 30hz.
I think its weird that I can get 60hz in windows, but on MacOS. Would Getting a HDMI 2.0 cable help?
This is what my window looks like in Mac OS
