Could you attach the lg 5k monitor to a second TB3 port on your Mac and have the eGPU running through it via its TB3 cable connected to the other TB3 port on your Mac?

So to be clear-

On the MacBook Pro 2017:

1st TB3 port: LG 5k monitor

2nd TB 3 port: eGPU

FCP 10.3 enhanced via the eGPU and displayed on the LG

1. Plug in eGPU
2. Plug in headless adapter (to eGPU)
3. In System Preferences --> "Displays" drag the white bar over to the headless adapter "screen" to make that your primary display.
4. While holding down the option key, click on the white rectangle representing your laptop's internal display and hold. Continuing to hold the option key, simply drag and drop your laptop display rectangle on top of the headless adapter 'display' rectangle.

Done.

MetalBench calculations show my performance hit (vs. an accelerated external display) to be only 10%. (For me the difference is 720% faster than dGPU vs. 645% faster than dGPU. No brainer.)

I want to use this but the DisableMonitor app says:

I tried it once a few months ago. It's a pretty sketchy solution to the problem IMHO. I do not recommend this to anyone who asks, but if you've got a spare host you can use to test, that won't interfere with your main working computer if something goes wrong, you could give it a shot. Not sure what kind of "damages" are being described earlier but like I said... sketchy.

Bring peace to your computing life: stop trying to understand Apple.

Can you please provide more details on your setup?

Computer, external monitor (if any), graphics card and software or hacks you used to get this to work. 

Im really wanting a eGPU connected to my 2017 MacBook Pro and LG 5K monitor and this sounds like it might work

Hi,
maybe this question have posted yet, but I don't find a real solution for me.

I wondering if can play 3D games  (like world of warcraft) directly on my macbook pro screen with macos OR is it mandatory to buy an external screen. 

I see so many topics saying ok or no ok > so 'im lost.

My rig : macbook pro late 2013 and I want to buy AKiTiO Node + RX 580.

Thanks all

Success with this method for MBP w/TB 2016 10.13.6 and using geekbench to verify acceleration. But a few issues. I lose my finder/apps side bar from either screen and have to open apps through search function in upper right corner. Also it becomes difficult to determine which screen is regular and which is accelerated as the "switching" option feels broken after I switch a few times... maybe it takes some getting used to. Also not sure about this "1440x900 60Hz" setting that I'm matching for internal and ghost external... MBP has retina display and I'm confused why this seems to be the go-to setting to get everything working right.

@esatamacmodular For High Sierra, you can alternatively use set-eGPU.sh to accelerate apps.

I have a 15" MBP 2014 with a Nvidia 1070 Aorus Gaming Box, and by using  THIS method I'm able to use both internal display and/or an external monitor. Notice that running games on internal display would be slower because data have to travel both from the mac to the Box and vice versa.
