How to Use Notebook Thunderbolt External 4090 Graphics Card Expansion in Notch

Hi and welcome to the Notch forums. If you’re asking about how you can pick which GPU to use in Notch, you do this by going to “Preferences”, as listed in the manual: Preferences | Notch Manual 0.9.23

If you’re asking about why a particular eGPU does not work or does not show up in Notch, I’m afraid we’re unable to help with Windows debugging.

selecting the GPU, restart NOTCH and it can be used normally.
