Hello , according to the answer given in the post #4631 Tech Inferno Fan “The NVIdia driver will only activate the Optimus accelerated internal LCD mode if there is no dGPU detected. Check if you can disable your dGPU in the BIOS. If not, you can use the DIY eGPU Setup 1.30 software to do it: DIY eGPU Setup 1.30” I gather you can start a laptop screen itself from a eGPU system. Whenever the BIOS detects a non dGPU, an integrated or dedicated graphics. This is so?, because it would be the answer to my post # 4618I appreciate your answer to myself to buy supplies in the event that is yes.A greeting and thanks.
