Why the laptop display on iGPU instead of DGPU on PhysX configuration when DGPU selected?

Hi @mckenziedavid01,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

When your HP laptop shows the display output on the iGPU (integrated GPU) instead of the dGPU (dedicated GPU) in the PhysX configuration panel, even though the dGPU is selected, it’s usually due to how NVIDIA Optimus or hybrid graphics is configured.

Why does Display Show iGPU Instead of dGPU

1. Display is Physically Wired to iGPU:
   • On many laptops, especially thin-and-light or business models, the internal display is hardwired to the iGPU (Intel or AMD).
   • The dGPU (NVIDIA) is used for rendering, but the final output is passed through the iGPU to the screen.
      
2. NVIDIA Optimus Technology:
   • Optimus dynamically switches between iGPU and dGPU to save power.
   • Even if PhysX is set to dGPU, the display may still show iGPU because it’s the final output path.
      
3. PhysX Configuration Panel Behavior:
   • The panel shows the rendering path, not necessarily the active GPU for all tasks.
   • It’s normal for the display to show iGPU even when dGPU is actively used for rendering.

How to Confirm dGPU Is Being Used

1. Use Task Manager (Windows 11):
   • Open Task Manager > Performance > GPU 0 and GPU 1.
   • Check which GPU is handling the load during gaming or rendering.
      
2. Use NVIDIA Control Panel:
   • Go to Manage 3D Settings > Program Settings.
   • Assign specific apps (e.g., Blender, games) to use the High-performance NVIDIA processor.

I hope this helps.

Take care, and have an amazing day!
