T he choice of an eGPU (English abbreviation for an external graphics card) is the responsibility of taking your expectations into account. If you’re new (or not for that matter) to eGPUs, we recommend that you read our review of the best external graphics cards. This will allow you to approach the rest of this page with a higher understanding of the different products and components available to you. Just like the choice of any component of a computer.

In terms of possible fixes, if you've already opened NVIDIA Control Panel to configure the system to prefer the NVIDIA GPU for that application, the only other things I can think of at the moment would be to get the latest NVIDIA drivers directly from NVIDIA rather than Dell in case any Optimus bugs or application incompatibilities have been resolved, and then perhaps reach out to your CAD software vendor.The advantage of this method is that you will not have to take your computer apart. On the other hand, the price is higher than with a DIY method (Do It Yourself) … But you will not have to get your hands dirty! Choose your external graphics card connection system

There are some systems like the Precision 7000 Series models that have a BIOS option allowing you to choose which GPU controls the built-in display and the display outputs, but those systems have a more complex motherboard design that allows them to offer that flexibility. It's also why you can't have the NVIDIA GPU directly control external displays, because this is a hardware wiring design issue. And this is why you can't completely disable the Intel GPU without losing video output. This technology is called NVIDIA Optimus. Instead, it operates as a render-only device when needed, passing completed video frames to the Intel GPU for output to displays. On both systems, the discrete GPU is not directly wired to any display output, not even the one for the built-in display. In terms of possible fixes, if you've already opened NVIDIA Control Panel to configure the system to prefer the NVIDIA GPU for that application, the only other things I can think of at the moment would be to get the latest NVIDIA drivers directly from NVIDIA rather than Dell in case any Optimus bugs or application incompatibilities have been resolved, and then perhaps reach out to your CAD software The Precision 5500 Series systems are the sister systems of the XPS 15 models. I know that there are some applications that still don't work with NVIDIA Optimus technology very well, even though it has been around for years now and is the most common design on dual GPU systems these days, but if this was an application compatibility issue, I wouldn't expect it to work on the internal display but not the external display. So if your CAD software behaves properly when you're only using the built-in display, I'm not sure why it would stop working properly when you attach an external display.


But again, that's true of the built-in display as well. The TB16 dock taps into the GPU outputs wired to the system's USB-C/TB3 output.
