Davinci Windows 10 iGPU/eGPU Confusion

I'm running a Razer Blade late 2016 model with the Devilbox containing an EVGA GTX 980 Ti FTW. Latest version of Windows with all updates, Razer Synapse updated, and NVIDIA drivers updated.

When I run Davinci Resolve, I manually specify the 980Ti and Davinci seems cool with that. However, the NVIDIA GPU Activity app tells me that Resolve.exe is running on the Blade's internal GTX 1060. The result is frame tearing in the timeline playback.

Every other app is running on the 980 Ti.

nvidia gpu
nvidia 980

Anyone else run into this issue? Is there some other way to specify which GPU gets assigned when launching Resolve? Or perhaps the 1060 is rendering the UI and the 980 is used purely for processing?

2016 Razer Blade (GTX1060) => PowerColor eGPU + EVGA GTX 980 TI FTW

I think what's going on is that Resolve is running on the GPU whose port it's being displayed with. So if you have your primary monitor connected to the HDMI port on the laptop, Resolve will run on the internal GPU. If you turn off the "use display GPU for compute" option then it will use the external port for compute, and the internal one for the GUI, as far as I understand it.

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.
