Hi, the USB-C DisplayPort Alt mode is connected to the integrated GPU (iGPU) by default rather than the discrete GPU (dGPU). This is typically done to optimize power consumption. You can set the laptop to dGPU only mode within the NVIDIA control panel and there is also the Optimus option in Predator Sense.

In the system block diagram i provided below is of your laptop. The Type-C port labeled as Type-C (Alt DP) is connected to the GN21 x2/x3/x4, which represents the discrete GPU (DGPU). This indicates that the Type-C port uses the DGPU for graphical output, specifically for DisplayPort Alt Mode functionality.

But I still recommned you to confirm, You can check using the NVIDIA Control Panel. Open the application and navigate to 3D Settings--> Set PhysX Configuration. Here, Look at the visual representation of your system's GPU connections. It will show which ports (e.g., HDMI, Type-C) are wired to the DGPU or IGPU.
