Hi all. 

I am buying a HP envy 27-b all in one. It contains a hdmi out and hdmi in port. The all in one includes a 4k display that is obviously connected to the computer. 

I have read to minimise framerate loss when using an egpu you should use an external display. 

Does this mean if i plug it into the hdmi in port it would be an external display and hence minimal framerate loss? 
Thank you

As soon as you connect the screen, (any screen), to the eGPU the applications running on that GPU will be shown on the connected screen. When utilizing the internal display, the data that needs to be processed by the eGPU has to travel trough the thunderbolt connection to the eGPU AND BACK! Therefore, when utilizing an external monitor, the data only has to travel through the thunderbolt connections once instead of twice, hence the improved performance.

In short:

Yes, IF you connect the screen directly eGPU.

However the HDMI cable should connect HDMI out on the eGPU and HDMI in on the monitor.

Thank you. And would you know whether the target display mode option would allow this kind of config on the hp? I.e. The computer can be on and hdmi in running at same time? Thank you I am receiving the computer on Monday so can't test till then

I can't say for sure as I've never dealt with a system as the Envy 27-b. If we assume that the system is able to utilize an eGPU the setup could potentially work if you can select which video source the screen uses like on a TV, or most other monitors in fact.

You would route the signal through the eGPU and then to the screen, instead of leading it back through the thunderbolt connection and through the internal connection to the screen.

But I guess you'll have to wait and see.
