Thank you for your wonderful work! I used your EFI to build hackingtosh on my t440p and it works like a charm except the external 4K monitor. My system configuration is like below:
Laptop T440p, upgraded with below:
CPU : i7 4800MQ /HD4600 integrated graphics, no discrete graphics driver.
Memory: 8G x 2
Main drive is replaced with a WD SATA drive, and another old plextor SSD drive placed in the DVD tray.
BIOS is not unlocked so wifi card is not usable, but it is OK for me now since I have wired connection.
Internal display is replaced with a FHD display.
an AOC U2790 4k external monitor.
I have a miniDP-HDMI 2.0 active cable, I tried Windows 10 in this laptop, and it works OK, monitor is recognized correctly and 4K@60 resolution is working good.
However, in macos, the default resolution of the external monitor becomes 1920x2160, something very wired. And if I switch from "Default" to "Scaled" in Displays settings, I can get 1920x1080, but there's no 4K (3840x2160) option. For now I can only get the external 4K monitor working at 1920x1080.
I have another miniDP-DP cable, I tried but same issue.
