Nah, just though if you figure out how to get both displays working directly on boot without having to restart.

ok，if I have some thing new, I will share it at here.
 
Just wanted to say I have been trying to get my optiplex 7040 to boot to the installer for hours and I assumed that the 7050 was close enough and this EFI folder worked! I am typing this from High Sierra. I haven't gotten all of the problems solved, like sleep and audio, but I only need to use one display so I don't think I will run into the shutdown problem.

Port remap.
com.apple.driver.AppleIntelSKLGraphicsFramebuffer
01050900 00040000 87010000 02040A00 00040000 87010000 03060A00 00040000 87010000 ->

no need for 4 monitors patch.

1. Connect both monitors to DP port. Only turn one monitor on, other keep off.
2. Boot. Entry to desktop
3. plug the dp port for off monitor, turn on the monitor, plug dp port back.
4. crashing.
5. Turn off the monitor immediately.
6. Boot. Entry to desktop
7. plug the dp port for off monitor, turn on the monitor, plug dp port back.
8. Two monitors with DP.


Note:
I select iMac17,1 in config.plist. and patch with black screen patch. (just search imac17 black screen)

I believe this problem relates to DVMT pre-allocation. I had decrypted 7050 sff biso, however, there is no any place to modify the DVMT pre-allocation.

The first restart should increase the DVMT memory, so the in the second time the driver won't crash.

Thanks! If you figure out how to have both monitors on during boot without plugin in and out please get back to me :).
How did you do the remap? Have you got any good guide on this, tried to search internet before but gave up trying to change remaping.
