没用过hidpi 但是推荐你检查一下一下几个方向:
- patched IOKit framework (to remove pixel clock limitations)
- DVMT-prealloc set to 96MB or 128MB in BIOS
- Haswell: ig-platform-id 0xa2e0008
- Haswell: framebuffer configuration for 0xa2e0008 patched to match DVMT-prealloc value (Broadwell determines BIOS size dynamically)
- "normal" requirements for Haswell/Broadwell systems
