Hi Weklin,
I appreciate your technical expertise. Thank you for sharing the information in detail. Yes, there is an option in BIOS from where you determines which video controller becomes the primary video controller when two controllers are available in the system. Here are the steps:
- Boot to BIOS using the F2 key when you power on the system. You will get the below screen:
![]()
- Click on the '+' sign next to the 'Video' tab to expand it.
- Select the primary video controller of your choice.
![]()
- Save and exit the BIOS setup.
- Restart the system and check functionality.
Hope this helps. Please reply with the findings.
