Yeah I know, this sounds like a bit of an impossible challenge. 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). This will probably have to be done with some sort of adapter. But I guess those aren't available yet for HDMI 2.1 (which this TV supports). 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. Currently I'm stuck on 4K 30Hz anyways.. Which brings me to my next question.
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. Right holding Alt/Options as well, but the only option I have is 30Hz, which is not acceptable. Via bootcamp I can run windows in 1080p 120Hz. If that's possible on Mac OS too, it would be awesome. But I guess this will have to be done with some sort of command line trick?
The sole reason I want 120Hz is for the smooth experience. And maybe enjoy some old (very little demanding) games on a higher frame rate.
You can find the specs of the Macbook I have right here:

I'm currently using the HDMI out on my Macbook to connect to the TV.
(Side question: Is there currently even a GPU available that supports HDMI 2.1?)
