Regarding how to set up discrete and integrated graphics in the BIOS, please note that the BIOS interface will be different for different computer brands and models, and here are the steps in general:
1.Access the BIOS
First, you need to go to your computer's BIOS settings interface. Restart the computer and press the specified key (usually Delete, F2, F10 or F12, etc.) during the boot process to enter the BIOS. You can see a message when your computer starts.
2.Navigate to Display Options
Once you are on the BIOS settings interface, you will see various options and menus. Use the arrow keys on your keyboard to navigate to the relevant Display, Graphics, or Graphics options. The specific name may vary depending on the BIOS version.
3.Toggle the graphics card mode
In the display options, you may see an option called "Primary Display", "Graphics Configuration", or similar. Select that option and look for the settings that control the mode of the graphics card.
4.Integrated graphics mode
If you want to use integrated graphics, select "Integrated Graphics", "Onboard Graphics", "IGPU", or similar options. Make sure this option is enabled or set to Priority.
5.Discrete graphics mode
If you want to use a discrete graphics card, select "Discrete Graphics", "Dedicated Graphics", "GPU", or similar options. Make sure this option is enabled or set to Priority.
6.Save and exit
Make sure to save the settings in the BIOS interface before making any changes. Normally, you can press the specified key like F10 to save the settings and exit the BIOS interface.
Please note that BIOS settings may vary depending on the make and model of your computer. Some computers may not even support switching graphics mode directly in the BIOS. Please read your computer's BIOS documentation or the relevant information provided by the manufacturer carefully to understand the exact steps and options before making any changes.
In addition, some computers offer the option to change the graphics card mode through operating system tools or specific software. You can check your computer manufacturer's resources or resources for more information on switching graphics modes.
