I’m trying to find a cable and/or adapter that will give me 4k 60hz with this combination. I have tried an off-brand Mini DP to HDMI cable that claims to be active and able to output 4k 60hz. However, the best I can get out of my 2015 Macbook Pro is 4k 30hz or 1440p 120hz. The TV receives a signal when set to 4k 60hz but it just displays a horizontal green bar across the top of the display.

Hi Bootz,

I would suggest to use an active adapter like the CAC-2170 with a certified HDMI 2.0 cable.



And use this software to create a custom resolution, with the below settings.


Let me know if it worked 🙂
