Using two monitors is a pretty simple concept. You'd think all you'd have to do is simply plug any video display into the appropriate port on your laptop or PC and you're good to go. The multiple monitors should instantly turn on and start working, right? Well, that's not usually the case.
There are many things to consider when you want to use two more monitors. Does your computer support dual monitors? How many outputs does your graphics card support? What kind of video ports does your computer have?
Once you've answered these basic questions, you're ready to begin configuring your multi-monitor setup.
There are three things to keep in mind when you want to use additional displays with your computer.
This article will cover each of these areas and help you troubleshoot issues you may be having with your extended displays.
Before you start running cables into the ports on the back of your PC or the sides of your laptop, stop and take a look at those ports so you know what you're looking at.
Modern computers handle video through an HDMI port, but older computers have a variety of other ports:
Many computers include a mix of these ports. When looking at the back of your desktop PC or the side of your laptop, you should see one or more of them.
Normally, if your computer has two ports, the video card is usually capable of sending an output signal to both. If there is only one port, then you probably can't.
However, your desktop may have slots available for additional video cards. So even if there is only one port on your desktop, feel free to open the lid and look for available slots for another video card.
When it comes to laptops, another option is to purchase and use compatible docking stations. You may have a docking station option that could extend your laptop (which may only have a single video port), to a docking station that has two or more ports.
So if you only have one video port available, definitely look into graphics cards Integrated Graphics Card vs. Dedicated Graphics Card:7 Things You Need To Know Integrated Graphics vs. Dedicated Graphics Card:7 Things You Need To Know Wondering if you should use an integrated video card?

If more than one is listed, then the card may be displayed on multiple monitors.
If you only see one, you should exit here because even though there are two ports, the card can only use one at a time. Much of your success at this is down to hardware capability, so checking this out first is most important.
However, if you've confirmed that your video card can “see” all the displays you've connected, yet can't seem to get additional monitors to work, don't give up. There are some techniques you can use to fix your own problems.
If you're still not sure if your computer can support dual monitors, another option is to investigate your graphics card.
First, find the brand of your graphics card.
Head over to Google and research the brand of your graphics adapter, followed by the word "multi-display" or "multi-monitor."

This is great for using a laptop with a second screen when you're on the go.
