    @Jake Lo I used apple native bcm9436cs2 card with converted case in my latitude 7400, don't need extra kext driver . I set empty to the boot args. I had tried one-key-hidpi script before, also failed. I looked up large articles to solve the 4K monitor problems, seems this issue related framebuffer dvmt.

    Thanks for your EFI. It can work at my dell latitude 7400 as your description. But I found a problem with my outer 4K monitor. When I connect a 4k monitor to the HDMI port on my laptop I can only select 1080p/60. I've used RESx and can force 1440p but still not 4k 24/30hz (HDMI port is only 1.4). In windows it will do 4k 24/30hz.
