Connect multiple monitors to your computer, and then set up the configuration in Windows 10. Plug in and power on your monitors, and then connect them to your computer. Connection types vary depending on the monitor and computer, but most commonly use an HDMI or DVI connection. On your computer, right-click the desktop
and select Display settings. To find out which screen is associated with each number, select Identify and then arrange the displays on-screen to match your setup. Select Apply to update the arrangement. Select the monitor you want to use as the
main display, and then scroll down and select Make this my main display. Select the Multiple displays drop-down list. Duplicating desktops shows a mirror image from one display to another. If you don’t see your desired duplication
options, select a different monitor, and then select the drop-down list again. Extending desktops expands the work area across multiple displays. Showing a single desktop enables the workspace only on the selected display and turns off all others. Disconnecting a display turns off the selected screen without needing to disconnect the cable. Select your desired configuration from the
drop-down list, and then select Keep changes. If desired, adjust any additional settings
such as scaling and resolution, and then close the Display settings. Windows displays the selected monitor configuration.
