    In this guide (5 steps):

    1. 1.Check your computer's ports

    3. 3.Plug in the second monitor
    4. 4.Arrange the screens in settings
    5. 5.Pick a main display
    1

    Check your computer's ports

    ~15s
    Look at the back or side of your computer for video ports: HDMI is a small trapezoid, DisplayPort is similar but with a notch, and USB-C is oval. Laptops often have HDMI or USB-C.
    2

    Buy the right cable

    ~15s
    Buy a cable that matches both the computer and the monitor. If one has HDMI and the other has USB-C, buy an HDMI-to-USB-C cable or an adapter.
    3

    Plug in the second monitor

    ~15s
    Plug the monitor into a wall outlet, then connect one end of the cable to the monitor and the other to the computer. Turn on the monitor.
    4

    Arrange the screens in settings

    ~15s
    On Windows, right-click the desktop and pick Display Settings. On Mac, open System Settings, then Displays. Drag the two screen boxes to match how they sit on your desk — this tells the computer which side the mouse should cross over.
    5

    Pick a main display

    ~15s
    In the same settings, scroll down to Multiple Displays. Tick the box for Make This My Main Display on the monitor you want as your primary — that is where the taskbar or dock and new apps will open.

    Two monitors give you roughly twice the workspace. You can keep email open on one screen and a document on the other, or have a video call on one while taking notes on the other. Most people who try dual monitors never go back.

    You need a second monitor and a cable to connect it (HDMI, DisplayPort, or USB-C). Setup on both Windows and Mac is automatic — plug it in and the second screen works right away.
