![]() It’s called NVIDIA Optimus and it has existed for quite a while now. ![]() Most laptops with dual GPUs these days have all outputs wired to the Intel GPU, but the NVIDIA GPU can still act as a render-only device that passes completed video frames to the Intel GPU for transmission to the display. That said, that doesn’t mean that your NVIDIA GPU can’t be used to accelerate content on the display attached via USB-C. They have DisplayPort multiplexers on the motherboard that allows you to change which GPU controls various display outputs, but that is a very rare design. Unless your system has a BIOS option that Dell calls “Graphics special mode”, this is a hardware property of the system that you can’t change, and to my knowledge that BIOS option is only available on recent Precision 7000 Series models. ![]() Looks like the USB-C display output is physically wired to the Intel GPU rather than the NVIDIA GPU.
