Things to check before the start

Generally speaking, most Windows laptops now support dual monitors, at least. But you need to make sure your laptop is capable to add two external monitors. And that depends on your Windows operating system, the capability of your graphics cards and drivers.


Windows XP/7/8/10 all support multiple monitors, so you just need to check the graphics card and ports on your laptop.

Check the graphics card

First of all, you may need to make sure your graphics card supports multiple monitors. Normally, every graphics card provides at least two outputs, but you will need to check the graphics card properties on the manufacturer’s website, find your graphics card and check the specifications to see if it supports adding two external monitors.

For example, if you are using NVIDIA GeForce  graphics card, you can check it out on the official website, and click your graphics card, and check the specification, then you will see if it supports multiple monitors.

If it does not support adding multiple monitors, you may need to buy and install a correct graphics card (e.g GeForce GT 610) before you keep processing. 

Check available ports on your laptop

Then you may need to check the ports on your laptop. Generally a computer or laptop should include any of these four ports: 

Display Port can provide an interface with an optional audio high-definition content protection.
Digital Video Interface (DVI) is usually color-coded with white plastic and labels.
Video Graphics Array (VGA) is normally color-coded with blue plastic and labels.
High-Definition Multimedia Interface (HDMI) can connect all kinds of video devices and provide sounds through the cable.

You can check the ports on the back or on the sides of your laptop. In addition to the ports on your laptop, the monitors should have the corresponding ports as well. That will save your time and money to connect them. Otherwise you will need to buy an extra adapter, such as DVI to HDMI adapter to have them match.

Tips: If your laptop only has one port, or if the ports of your monitors does not match with the ones on your laptop, you can buy an adapter, a switch splitter or a docking station to work it out. For example, you can buy a HDMI to DVI adapter, a HDMI splitter to have two HDMI ports, or a docking station to have the needed ports. That will solve your troubles.

How to set up two monitors

If everything is ready, you can start connecting the two monitors to your laptop.

Note: Connect your monitors while your laptop is turned on. In most cases, Windows will detect when a new monitor is plugged in. 

For example, I have VGA and HDMI ports on my laptop, and my external monitors have cables for VGA and HDMI ports as well:

1) Plug the cable of the first external monitor to the correct video port on your laptop. So I plug the VGA cable of the first external monitor into the VGA port on my laptop.

2) Plug the cable of the second external monitor to the other correct port on your laptop. So I plug the HDMI cable of the second external monitor into the HDMI port on my laptop.

3) On your laptop, right click an empty area of your desktop,
if you are using Windows 10, click Display settings,

if you are using Windows 8/7, click Screen resolution.

4) You will see three displays labeled with 1, 2 and 3 in display mode. Generally speaking, the display 1 is the monitor of your laptop, and the display 2 and 3 are the external monitors. (What if you can’t see the plugged-in monitors?)

5) Click the display 2, and select Extend desktop to this display in Multiple displays, and click Apply

6) Click the display 3, and select Extend desktop to this display in Multiple displays, and click Apply

7) Click OK to finish the settings, and you can now use the three monitors on your laptop.

Tips: You can click and drag each display (1, 2 or 3) to rearrange the display. You can also change the size of itemsdisplay resolution and orientation according to your preferences.

What if you can’t see the plugged-in monitors?

Sometimes the external monitors cannot be correctly detected by your laptop. This can be caused by the improper connection, defective monitor or cables. Ensure all the cables connect correctly, and do some tests with an alternative monitor and another cable.

If it still does not work, it seems like your graphics card driver cannot properly support multiple monitors display. A driver update is necessary.

If you are not sure how to do that, we recommend Driver Easy  for you. Its free version can detect and download the outdated drivers on your Windows with only a few clicks.

You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks (and you get full support and a 30-day money back guarantee):

3) Click the Update button next to a flagged device to automatically download the correct drivers (you can do this with the FREE version). Or click Update All to automatically download all the correct drivers that are missing or out of date on your Windows (this requires the Pro version – you’ll be prompted to upgrade when you click Update All).
