Install Display Menu app (available for free on AppStore) to check if you can switch from mirrored displays to separate/independent displays.

 

Your IOReg shows:

  1. [email protected]:
    • ​no attached display
  2. [email protected]:
    • connector-type = 00 04 00 00 (DP)
    • port = 0x5
    • boot display = true
  3. [email protected]​:
    • ​connector-type = 00 04 00 00 (DP)
    • port = 0x6
  4. [email protected]:
    • ​no attached display

 

Which framebuffer layout-id are you using? Once you've identified it, you can try to identify the framebuffer table in the Skylake framebuffer kext and investigate a potential binary patch.
