Plug the monitor into the GPU you want to use. I think folk with laptops get the option of which GPU to use due to it's design but here, you plug into the GPU you wish to do the work.
I am running off a desktop computer with the current specs:
Ryzen 5 2600x
NVIDIA Geforce GTX 1050 ti
NVIDIA Geforce GT 730
My problem is that while it is easily possible to choose what gpu applications run off of using windows if you have an integrated graphics processor. Ex: GTX 1050ti + Intel HD Graphics. I was unable to find a way to choose between two discrete graphics cards. EX: Make chrome run off of gt 730 instead of gtx 1050ti.
Any solution is appreciated, i'm desperate.
