I have tried using SwitchResX and ResXtreme to change the resolution and refresh rate, however any option above 1080p can only run at 30Hz. DR - Windows can run this monitor at 4K 60Hz over DisplayPort.
#MACBOOK PRO 4K 60HZ SWITCHRESX MAC OS X#
I'm currently using the HDMI out on my Macbook to connect to the TV. MacBook Pro MacBook Air Mac OS X Support Mac Software Other Apple Hardware Laptops. You can find the specs of the Macbook I have right here: And maybe enjoy some old (very little demanding) games on a higher frame rate.
The sole reason I want 120Hz is for the smooth experience. But I guess this will have to be done with some sort of command line trick? Test Config: MBP with IG: Mid-2014 Macbook Pro Retina with Integrated Intel Iris Pro graphics, High Sierra. Please review my test results below before responding. The HiDPI scaled resolutions are important for my application. If that's possible on Mac OS too, it would be awesome. My goal: 3840x2160 60Hz AND 2560x1440 scaled 60Hz on MBP Mid-2014 with Integrated Intel Graphics, Macos High Sierra -> MDP-HDMI -> Samsung MU7000 4K TV. Via bootcamp I can run windows in 1080p 120Hz.
However I was told by this forum and others (posting screenshots with 4K60hz) that there is a workaround where I am able to achieve 4K at 60hz or at least 50hz. I know the early MBP 2013 doesn't natively support it. Right holding Alt/Options as well, but the only option I have is 30Hz, which is not acceptable. I am on a early 15' Macbook Pro Retina Display with dual Intel 4000 and Geforce 650M GPU. Is it possible to run 120Hz in general on Mac OS on this TV with my Macbook? Currently I can't get the option to appear. I do know that there is a StarTech Mini DisplayPort to HDMI 2.0 adapter which should enable me to run 4K 60Hz on it. But I guess those aren't available yet for HDMI 2.1 (which this TV supports). This will probably have to be done with some sort of adapter. But would it be possible to run 4K 120Hz on my new LG OLED C9 TV (55 inch model) while using my Mid 2014 Macbook Pro? (I have the one with a GeForce GT 750M 2GB inside). Yeah I know, this sounds like a bit of an impossible challenge.
