How To Add A Second Monitor

Get A Real Boost Using “Multi-Monitor”

One of the best ways to improve your productivity is to double your desktop workspace by adding a second monitor to your computer. Using multiple monitors makes many computing tasks easier by allowing you to keep more windows visible. And, it’s “kewel” too.

There are many ways to add a second monitor to your PC.
* Laptops [typically] have a graphics port, allowing you to use the screen and a monitor. dongle
* Most graphics cards have two ports (often, one is a VGA and the other is a DVI, so you may need an adaptor). If yours doesn’t, you can buy a “dongle” and ‘split’ the signal– as shown.
* You can add a graphics card to your machine. This is a little more advanced but quite do-able. I posted a tutorial on adding “expansion cards”, but it was on adding a Firewire card. No matter. The methodology is the same. See, Add Firewire 800 To Your PC– Fast Video Transfer

Tip of the day: Plug in a second monitor and turn on Dualview

1. Right-click the desktop, and then click Properties.

Desktop Options menu with Properties selected

2. In the Display Properties dialog box, click the Settings tab.

3. Click the Display list and select your external monitor. If you do not see multiple monitors listed, your computer hardware may not support Dualview. Contact your computer manufacturer for more information.

4. Select the Extend my Windows desktop onto this monitor check box.

5. Click Identify. Windows XP displays large numbers to identify your monitors. Drag and drop the monitor icons to match the physical arrangement of your monitors.

6. Click OK.

With Dualview enabled, you can drag windows between monitors as if the two monitors are connected. When you maximize a window, it will expand to fill the current monitor.

  1. TechPaul,

    Excellent instruction on this… Ironically I’m working on a system where I am setting this up… Perfect timing!

    • Rick,
      There’s no doubt about it; once you have a dual monitor setup, you’ll not want to go back.

      I am working on a troubleshooting dual monitors article, and maybe, one of these years I’ll get it up…

    I tried following your instructions to turn on dualview and use two monitors but the second monitor shows the same as the first. When I try to identify the 2nd monitor, no # 2 appears the same way a # 1 appears when I choose identify on the first monitor.

    What am I doing wrong ?

  3. Eric,
    It may not be that you are doing anything wrong at all. As you probably noted in #3, not all hardware (nor software) supports DualView. You did not tell me any relevant details (operating system, graphics cards, etc..) so I will only be able to provide “general” assistance to you.
    1) Make sure the 2nd monitor is being recognized. (You do this in Device Manager).
    2) Make sure you have the latest device drivers for your graphics adapter and your monitor. Visit the manufacturer’s websites and download + install the drivers appropriate for your version of Windows.
    3) If these steps fail.. you may need to hire the services of a tech.. and/or buy a newer graphics card.
