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 is usually color-coded with white plastic and labels.Video Graphics Array is normally color-coded with blue plastic and labels.High-Definition Multimedia Interface 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.
If you dont have the match ports for your laptop and your monitor
If the ports in your laptop is not the same as the connectors in your monitor cables, dont give up hope. There is workaround! You can try one of the methods below to continue:
- Use an adapter, such as an HDMI to DVI adapter. This works if you have two different ports for your laptop and your monitor.
- Use a switch spillter, such as a Display splitter to have two HDMI ports. This works if you have only one HDMI port on your laptop but you need to HDMI ports.
- Use a docking station, and it works in various circumstances.

Can You Connect Two Monitors To Your Laptop Or Pc
Here’s what you need to consider when you want to use extra displays with your computer:
This article will cover each of these areas and should help you troubleshoot the issues you may be having with your extended displays.
Check What Ports Are Available

Before you start shoving wires into ports in the back of your PC or the sides of your laptop, stop and take a closer look at those ports so that you know what you’re looking at.
Modern computers handle video via an HDMI port, but older computers feature a variety of other ports:
- HDMI: A High Definition Multimedia Interface port is a computer interface that transmits uncompressed video and audio.
- DisplayPort: A DisplayPort was originally designed as a superior video port to older VGA and DVI ports, but is far less popular on modern computer systems than the HDMI port.
- DVI: The Digital Visual Interface was originally designed by the Digital Display Working Group, and was next-generation to the inferior VGA port. Many older computers have one of several configurations of the DVI port.
- Thunderbolt: A Thunderbolt port is a combination of several technologies, including DisplayPort and PCI Express, in combination with a power supply to power the external display if required.
- VGA: Older computers typically come with the famous blue VGA port. The 15-pin VGA has been used for computer video for many years, but has been largely replaced by the newer video ports like Thunderbolt and HDMI.
Many computers include a mix of these ports. Examining the back of your desktop PC or the side of your laptop , you should see one or more of them.
So, even if you only have one video port available, definitely research the graphics cards if you want to set up a dual monitor laptop.

Use Your Laptop As A Desktop
When you connect a laptop to a separate screen, that basically makes your computer a desktop. Convenient, since it gives you a larger screen to work on. On top of that, you’ll only need to use 1 cable to connect your laptop: the video cable. This is often the HDMI cable. You can insert USB flash drives and hard drives directly into your laptop. Leaving the house? All your files will, of course, simply come with you. When you get home, you’ll pick up where you left off immediately.
Spread Your Desktop Across Your Laptop And Monitor
You can show different content on your laptop and monitor by selecting “Extend these displays.” In this mode, you can move your mouse beyond the edge of one screen to enter the other. This also lets you drag and drop windows onto both displays. So, you could have one program open full-screen on your laptop display and another on your monitor.

How To Use Your Laptop As A Second Monitor
Adding a second monitor to your workstation is an excellent way to expand your productivity, and while the best computer monitorsare great for this, you can use your laptop as a second display, too. This is pretty useful, as you can save some money by using a laptop that you already own instead of buying a brand-new external monitor to use. You’ll be able to do this as long as both your main PC and your laptop support wireless Miracast connectivity.
In this Windows 10 guide, we’ll show you how you can successfully use your laptop as a second monitor.
Check Your Video Card Settings
If you have two ports, but you can’t seem to get both ports to work at the same time, the next step is to determine if your video card even has the ability to display to multiple monitors.
It’s easy enough to check: Just plug in both monitors, then press Windows + I and go to System > Display.
In the display settings, you may actually see the multiple displays come up, with some disabled and others set up as either your primary display or as an extended display.
You can ignore those for now and instead click on Advanced display settings at the bottom of this window.
On the next page, you should see Display information for each connected display if your graphics card “sees” the number of monitors that you’ve plugged in.
If more than one shows up, then the card is capable of displaying to multiple monitors.
If you only see one, then you should quit here because even though you managed to connect multiple displays, the card is only able to utilize one at a time. Much of your success in this comes down to hardware capability, so checking this first is the most important thing.
However, if you’ve confirmed that your video card can “see” all displays that you’ve plugged in, yet you can’t seem to get additional monitors to work, don’t give up. There are a few more things you can try to fix the issue.

Using A Large Screen And High Resolution With A Laptop Makes It Even More User
The biggest merit of connecting a laptop with a stand-alone LCD is that it gives you a large screen and high resolution dual display environment. Standard laptop models usually come with a built-in 13-inch to 15-inch wide-screen LCD with a 1280 × 800 dot or 1366 × 768 dot resolution.
This level of resolution is good enough for basic Windows operations, but it goes without saying that a large, high-resolution computer screen is much more user-friendly. Combining a laptop with one of the latest wide-screen monitors enables you to easily construct a large-screen, high-resolution dual display environment. It is a real boon to dramatically boost the screen size and resolution while continuing to use your familiar laptop.
In particular, the increased vertical resolution makes applications such as web browsers and document display and editing far easier to use. For example, you can do things like check things with the web browser, refer to pdf files, organize data using word processing or presentation software, and create spread sheets and documents without having to change windows.
At the office, it is very helpful for presentations to use “clone view” for the laptop’s built-in LCD and the external LCD screen. Clone view means showing exactly the same content on two display screens. It is normally set by a graphics driver function.
Clone view displaying the same content on two screens is very effective when used in presentations |
Show The Same Output On Your Laptop And Monitor
Windows defaults to “Duplicate these displays.” So, what you see your laptop screen is what you see on your monitor, and when you move your mouse on one screen, it will also move on the other. In this mode, your monitor may not receive a full resolution signal if your laptop graphics card is not powerful enough to deliver the full resolution to both displays.

Easy Ways To Connect A Laptop To A Monitor
Did you know that nine in 10 connected households in Australia either have a PC or a laptop computer? Or that over 40% of Australian households also have an Internet-connected TV?
That’s right! Moreover, there are now about 40 million computers in Australia alone.
As amazing as PCs and laptops are though, their single-screen display can be a little too limiting. Especially for those who multitask and need to open more programs and apps than the average user.
The good news is, there are several easy ways to set up your laptop so that you can use another monitor with it. Meaning, you can have multiple display screens with a single laptop.
Ready to get the most out of your laptop? Then keep reading as weve covered five of the best ways to connect your laptop to an external screen!
Finding The Right Cable

If you find yourself having to use VGA, its more likely than not your device is relatively ancient. Similarly, if your device doesnt feature a VGA port at all, to which most modern, slimline notebooks can contend, this option wont suit you either.
These cables only carry image feeds – and not sound – so youll need to connect a separate audio connector to rig yourself up properly. You might be able to find a VGA to HDMI convertor but they tend to be disproportionately costly for the quality of the connection you end up with.
Wed recommend that you avoid using VGA connections if you can help it. Its technical limitations are unsuited to modern connectivity, so its best to seek out a more modern alternative.
DVI is similar to VGA but is capable of far higher resolution. Using a converter from DVI to HDMI will garner better results than VGA, but its still not ideal.
HDMI should be familiar to most people, as its the standard connection used by most televisions. There are variants though, so be aware. There are mini-HDMI and even micro-HDMI connectors, as well as full size, so make sure you pick the right cable.
Dont spend ridiculous amounts of money either HDMI cables are digital, and so either they work or they dont. You wont get better quality from fancy bells and whistles like gold-plated connectors, and buying a cheap one with the right spec will work just as well as an expensive one.

Wider Image For Office Documents
Most laptop screens are between 13 and 15 inches. Because of this, Office documents such as spreadsheets filled with data aren’t always clear. Using an external screen with your laptop? In that case, you can display an entire spreadsheet on your laptop screen and your monitor screen. That way, you’ll find what you’re looking for more quickly, and process data more effectively.
How To Add A Third Monitor To Your Laptop
If you spend any significant amount of time working at a desk, the single best way to boost your productivity is to connect a second monitor.
Most laptops have either a VGA or HDMI output, making the addition pretty simple: just connect the LCD, tweak Windows settings to extend your desktop, and then enjoy the benefits of a double-size workspace.
Ah, but why not go a step further? Why not extend your desktop even further with a third screen?
Simple: few desktops, and almost no laptops, have a second VGA or HDMI output, meaning theres nowhere to connect that third screen.
Ah, but there are workarounds. If you happen to have an older and/or spare laptop lying around, you can install MaxiVista . It leverages your laptops network connection to extend your primary Windows desktop, meaning theres no physical connection required between the two machines.
Another option: take advantage of a spare USB port, which can drive a third monitor when connected using a USB-to-DVI or USB-to-VGA adapter. You can find these adapters online for around $40-50.
Finally, dont overlook monitors expressly designed for second- or third-screen duty. Right now Im liking the AOC e1659Fwu , a 16-inch LCD thats actually powered by USB, meaning it requires no separate AC adapter. I wouldnt call it portable, necessarily, but its definitely easier to maneuver than a traditional monitor. Plus, it works in both portrait and landscape modes.

Laptops are the perfect choice for working on the go, but their relatively small displays can often leave a bit of a hindrance. Hooking up a second, third, or even fourth screen can help give you a little bit of breathing room and make your workload feel much more manageable.
Essentially, having multiple displays means you dont need to flip between applications on one screen anymore. For example, you can display your email client on your laptops native screen and run Photoshop on a bigger external monitor. Maybe you have one monitor dedicated to Slack and another for browsing.
This article explains how to hook up your laptop to your external monitor and configure the display to work the way you want. There are also details on resolution limitations for various connections and advice on finding the correct adapter if your video inputs dont match.
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 manufacturers 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 before you keep processing.
