Set up dual Windows on the monitor

To make your computer recognize multiple monitors, do the following:

Make sure the cable is properly connected to the new monitor, then press Windows + P to select display options.

If you need more help, you can do the following:

Select Start, then open Settings.
Under System, select Display. Your computer should automatically detect the monitor and display the desktop. If you can’t see the monitor, select Multiple Monitors and then Detect.
Use the drop-down list next to the desktop image to select how the screen will appear on the monitor.
After selecting the Settings, select Apply.

You can change the resolution of the monitor. However, we recommend using the recommended resolution to get the most out of your display.
