Here is how to adjust between using built-in CPU graphics and NVIDIA graphics on a laptop that offers switchable graphics.1. Check to see that both display drivers are installed in the system properly. You can check this by going into the Device Manager and opening Display Drivers from there. You should by default see the CPU on-board graphics (Intel) along with the NVIDIA driver. 2.Open the NVIDIA Control Panel. You can right click on an empty part of your desktop to bring up a menu where you can select the NVIDIA Control Panel. 3. Within the NVIDIA control panel, select the Manage 3D settings on the left. 4. On the Manage 3D Settings page, you can select Global Settings and change the Preferred graphics processor. For High-performance (more powerful but less energy efficient), select the NVIDIA. For more energy-efficiency but less power, select Integrated graphics. 5. You can also go into Program Settings if you want to change the settings for an individual program rather than the system as a whole.
