@ariksaja, yes, a ghost adapter can provided an eGPU accelerated internal LCD mode in Windows if your system doesn't have active iGPU for NVidia Optimus functionality to engage. Details as supplied by enjoy is at https://egpu.io/forums/pc-setup/guide-accelerated-internal-lcd-on-non-optimus-systems-enjoy/

See here!

PICTURES:

  • How to build you DVI dummy display using a 80-100 ohm resistor on C2/C5 pins of the DVI connector!

See here!

I don't think you need links, there is plenty of guides for build DIY ghost adapter. It is worth to mention them, along commercial solutions.

Since from long time i saw the discussion move forward, but none of these guides where mentioned.


A simple resistor is enough, admins do not implemented in the post the DIY HDMI/DVI ghost adapter, only commercial solutions!

Instead if you don't want to spend, just get a HDMI to DVI adapter and build your own ghost adapter using a 80/100Ohm  resistor.

Any news about accelerating internal display on High Sierra without headless? this is quite important for iMacs

I got ordered of these
https://www.amazon.com/gp/product/B00JKFTYA8/
Would this be fine?
 
I own a macbook pro 15" mid 2015 (with dedicated radeon) and ordered the aikito node, thunderbolt to usb-C adapter and thunderbolt cable.
Hope it all works Smile For me it's all for gaming in windows (bootcamp) on the internal display. Still deciding in which graphics card to buy. (Edit: Decided to go with nvidia 980 6 gb, as opposed to 1060 6 gb since apparantely the 980 usually outperforms the 1060 card still.
Should get all of those things next week.

In High Sierra, I have iStat Menus installed to monitor which gpu is being used, and when switching the app from running on the headless display to the internal display you can see it switch from the eGPU to the internal dGPU. If you mirror the headless display and the internal display it seems to accelerate on the eGPU correctly.

I have iStat here as well but can't figure out how to get to the GPU monitoring part. How do you do that?

Hello, I'm buying a Razer Core v2 + GTX 1070 ti + Apple Thunderbolt 2-3 adaptor. Hope it will works as needed:
- with or without and external display.
Thus, I'll only need to as a 10€/$ adaptor to create a "ghost display" ?

At the end, @Wesley Beernaert: does you build is up&running?

Old hardware: MacBookPro11,5 (15 Retina, i7 4980HQ) dGPU R9 M370X + TB2/TB3 adapter + Razer Core v2 + GTX 1070 Ti

New hardware: Mac mini (2018, i7 8700B, 32 GB RAM, 1 TB SSD)+ Razer Core v2 eGPU + SAPPHIRE Radeon RX Vega 64 + Samsung C27HG70 display
New software: macOS 10.14.2 (18C54), Windows 10 to be tried !

how do I accelerate both screen internal and external?

I have tried to set main screen to external via display port connected to the egpu and mirror the internal into the hdmi dummy plug also connected to the egpu

with the adapter I got rid of the flickering apps like safari and also pro apps such as Maya, substance painter and designer and marmoset toolbag

BUT, it seems that Maya can't see properly the graphics cards!
