How to Change Primary Monitor at Boot on Your Computer

To change primary monitor your computer uses at boot, you can adjust the settings either in your system’s BIOS/UEFI or in your operating system settings. Here’s how to do it:

1. Through BIOS/UEFI (Before the OS Loads)

• Restart your computer and enter the BIOS/UEFI settings. You usually do this by pressing a key like Delete, F2, F10, or Esc during the boot process (the exact key varies by manufacturer).
• Once in the BIOS/UEFI menu, look for settings related to display, graphics, or primary display adapter.
• Change the primary display setting to the desired monitor. This might involve selecting the monitor connected via HDMI, DisplayPort, DVI, or VGA, depending on your setup.
• Save the settings and exit.

2. Through the Operating System (After Boot)

• If you want to switch monitors only after the operating system has loaded, this can be done in the display settings:
  • Windows:
  1. Right-click on the desktop and select Display Settings.
  2. Identify the monitors by clicking Identify.
  3. Scroll down to Multiple displays and select which monitor should be the main display (this affects where the taskbar and desktop icons appear).
  4. Click Apply to save the changes.
  • macOS:
  1. Go to System Preferences > Displays.
  2. Click on the Arrangement tab.
  3. Drag the white bar to the monitor you want to be the main one.

If you want the boot sequence (BIOS, boot logo) to appear on a specific monitor, adjusting the BIOS/UEFI settings is typically required.
