Hello to community.

I succeed to make my egpu work on elitebook 8470p. Solution was the setup 1.35 program and Nando4!!!!On external monitor it works perfectly. I cannot make it work in internal monitor. It is like not accelareted, black white colors 640x480 resolution. Also intel HD has error 12 when eGPU is working on external monitor. Do i need to disable a port to free resources etc?

My specs
8470p HP (intel HD 4000 model)
8gb ram
gtx 750 ti
exp gdc V8 express card
win 10  18.09

What i did.
On setup 1.35 i set eGPU on 32 bit and saved
Then i run chainloader
eGPU is working
internal monitor is not accelerated
intel HD 4000 has error 12

Apologise for my english. Is there any solution or something i did wrong?

Finally eGPU is fully working on 8470p both external an internal screen. No problems at all!!!

You will need to dsdt override for large memory area. Then, after this, laptop recognizes both iGPU and eGPU and optimus decides when you use eGPU and when to use iGPU.
I have my intel HD 4000 for desktop and videos and when you launch game nvidia accelarates the game.
My results in heaven benchmark in internal screen.
1366x768 resolution
preset high
59fps
score 1550
