My MacBook Pro is A1398 15 inch Early 2013, it has NVIDIA GeForce GT 650M 1024MB and Intel HD Graphics 4000 1536MB. OSX is 10.12.6 Sierra, I bought a miniDP to HDMI 2.0 active cable from amazon de which is Club 3D 1180, and my monitor is LG 4k 27UK650.

Monitor Description blocks:

Before use CoreDisplay patch, I can get a 4k 35Hz with SwitchResX with less than 300MHz Pixel clock. Only CoreDisplay patch run successfully, Nvidia patch miss OSX 10.12.16 version. After reboot the system hung at apple logo loading. I have to boot with safe mode to restore the CoreDisplay file.

Is there any update step I missed?
