Hi ,rehabman thank you for your reply and sorry for the delay .Those two days i having been trying all by myself. And i have worked something out . I've installed Sierra successfully,and taken into the 4k resolution. Unfortunately, i can't move on without your help.
I noticed some useful stuff in your post “
http://www.tonymacx86.com/el-capita...aq-read-first-laptop-frequent-questions.html” which i think it's guidance.
What i've done :
- Haswell: ig-platform-id 0xa2e0008 (config.plist inject)
- DVMT-prealloc set to 96MB or 128MB in BIOS
i used "setup_var 0x2d2 0x4" in my case ( for 128MB) ,followed the guide linked in the posts . i found my
DVMT pre-allocated memory like this
Code:
0x33D61 Setting: DVMT Pre-Allocated, Variable: 0x2D2 {05 A6 D1 04 E3 04 1E 02 01 00 D2 02 10 10 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00}

According to what i'm sufferring ,maybe some parts of my operations weren't right . Plz help me point it out.
- patched IOKit framework (to remove pixel clock limitations)
i digged into the XPS9530.sh script .
and execute it in terminal .
Code:
# OS X - 10.12
sudo perl -i.bak -pe 's|\xB8\x01\x00\x00\x00\xF6\xC1\x01\x0F\x85|\x33\xC0\x90\x90\x90\x90\x90\x90\x90\xE9|sg' /System/Library/Frameworks/CoreDisplay.framework/Versions/Current/CoreDisplay
sudo codesign -f -s - /System/Library/Frameworks/CoreDisplay.framework/Versions/Current/CoreDisplay
after that, restart the laptop ,it stucks at apple logo. So i found another way using
CoreDisplayFixup.kext (https://github.com/PMheart/CoreDisplayFixup) to across pixel clock check. Am i doing right ?
- Haswell: framebuffer configuration for 0xa2e0008 patched to match DVMT-prealloc value (Broadwell determines BIOS size dynamically)

So far, i can see my external display under 3840x2160@30hz using dp port（should be 60hz）. But still get some issues：
After i boot ，here i am （with the internal display a splash screen ,and the external display screen blurred）
