Connect to an external display

Connect to a wired display

Connect the external display to an appropriate video connector on your computer, such as the HDMI connector, the USB-C connector (USB 3.1 Gen 1), or the Thunderbolt 3 connector (USB-C).
Connect the external display to an electrical outlet.

If your computer cannot detect the external display, right-click a blank area on the desktop, and then click Display settings > Detect.

Do not connect external displays to the USB-C connector (USB 3.1 Gen 1) 1 and the HDMI connector 2 at the same time.

You can change the priority between the USB-C connector (USB 3.1 Gen 1) and the HDMI connector from the UEFI BIOS menu. To enter the UEFI BIOS menu, see Enter the UEFI BIOS menu. Open the Config menu, and then select Display > Shared Display Priority. Then, follow the on-screen instructions.
