How do I setup 3840 x 1600 @ 60 hz?

[MacL0ve]

Hello dear MacRumors Community,

I have a problem. I just bought the LG LG 38UC99-W for my MacBook to work on. The native resolution of the screen is 3840 x 1600.
To archive 60hz at higher resolution I followed this guide: https://github.com/Floris497/mac-pixel-clock-patch-V2

What I can do is to choose 3440 x 1440 @ 60hz but I have no option to use 3840 x 1600 @ 60hz. Does anybody have an idea to to archive this goal?

Best Regards,
MacL0ve

I am facing the same issue with an older imac. I found a workaround that might work for you as apple does not support 60hz 4k on most devices is appears...
