connect 2 lcd monitors to laptop free sample

We all know that multiple monitors can extremely improve our productivity and bring a great experience, especially when you’re using a laptop. But how to connect external monitors to a laptop? You’ve come to the right place. This article introduces an easy and clear guideline toconnect two external monitors to your laptop.

Note: the instructions below apply to adding multiple monitors for laptops, but it also works if you want to add external monitors to your PC/desktop.

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.

First of all, you may need to make sureyour 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 specificationsto see if it supports adding two external monitors.

For example, if you are using the 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 RTX 30 Series) before you keep processing.

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 a

If the ports on your laptop are not the same as the connectors in your monitor cables, or there are not enough ports, don’t give up. There is a workaround! You can try one of the methods below to continue:

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.

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.

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.

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

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

Automatically– If you don’t have time or patience to manually update drivers, you can do that automatically with Driver Easy. 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 a30-day money back guarantee):

Click theUpdatebutton next to a flagged device to automatically download the correct drivers (you can do this with the FREE version), and install it on your computer.

Or clickUpdate Allto automatically download all the correct drivers that are missing or out of date on your Windows (this requires thePro version– you’ll be prompted to upgrade when you click Update All).

These are the easy instructions to connect two external monitors for your laptop. Comment below if you have any questions, and we will see what more we can do to further help.

Whether in the office, home office, or for gaming – two screens are better than one. However, setting up dual monitors depends somewhat on available connections and cables. Read on to find out how to connect a second screen to a laptop or PC.

When splitting your Windows screen no longer suffices, you’ll need an additional monitor. Added screen space is easier on the eyes and simplifies working with several applications simultaneously. Gamers can enjoy high-resolution graphics by installing an additional monitor.

If you only want to view videos or pictures on a larger screen, you don"t need to install an extra monitor. With Windows Miracast, for example, you can easily connect your PC to a TV.

The majority of modern laptops and PCs support connecting a second monitor by default. All you need to consider are the ports on your end device and which monitor you’d like to connect. Before you head out to purchase one, be sure to check the type and number of ports on the laptop or PC.

HDMI (High-Definition Multimedia Interface) is one of the most common connection types of modern monitors and many TV users will already be familiar with it. The connection type is compact and transmits video and audio signals. A modern HDMI connection is suitable for 4K resolutions and a frame rate of 60 Hz. If your monitor and laptop or PC have one or two HDMI ports, you just need a single HDMI cable. If you want to connect two monitors but only have one HDMI port, use an HDMI splitter. Be sure that the splitter has the same refresh rate as the HDMI cable.

USB-C is a USB port format that’s often found on new, slim laptop models. The advantage of USB-C is that it can be used for charging while also supporting the transmission of audio and DisplayPort signals with Alternate Mode. DisplayPort refers to monitor interfaces for image and sound signals and high transfer rates. The USB-C downstream and DisplayPort Alternate Mode can be used to link several monitors. If you only have a few USB-C ports, use a USB-C dongle. Ideally, a USB-C donglehas at least two HDMI interfaces for monitors. Alternatively, a dongle can be paired with a HDMI splitter.

DisplayPort is similar to HDMI and transmits audio and image signals at high frame rates. Thus, the connection is particularly suitable for 4K. Laptops often have a DisplayPort or miniDisplayPort and can be connected to monitors that have a DisplayPort port. For monitors without DisplayPort, a corresponding adapter is required. Thanks to multi-stream transport, multiple monitors can be connected via DisplayPort and coupled to a laptop via a splitter or adapter.

DVI and VGA are analog, older connection standards that only transmit image signals. If the monitor and end device have DVI or VGA ports, they can be connected via the corresponding DVI or VGA cable. With the appropriate DVI-HDMI or VGA-HDMI adapter, older monitors can be connected to laptops and PCs to transmit HDMI signals. Modern connection standards are preferable in any case, as they offer better resolution, refresh rates, and color values.

Even if your laptop only has a single HDMI or USB-C port, you can connect dual monitors. Using a suitable HDMI splitter, a USB-C dongle, or a USB-C dongle with HDMI interface, you can easily connect two or more monitors to your laptop.

Once you connect one or more monitors to your laptop, you can set up two or more monitors in Windows and specify which monitor you wish to use as the main one. Windows usually detects display devices connected to the laptop or PC automatically and assigns numbers to them. The main monitor is designated number 1. All others are numbered in ascending order.

Step 2: Under “Display” and “Multiple displays” you will see display devices detected by Windows, e.g. one or more additional monitors. Click “Detect” if none are visible.

Step 3: Go to “Advanced display settings” to make changes to the arrangement and order of the connected monitors. Adjust further settings such as the screen resolution, for example.

Step 4: The easiest way to change the use mode of the connected monitors is to use the shortcut [Windows] + [P]. Settings such as “Duplicate” let you mirror desktop content. With “PC screen only” or “Second screen only” you determine whether you only use one of the connected screens. Use “Extend” to create a connected desktop from connected monitors. These options can be found in the “Display” menu under “Multiple Screens”.

Another problem could be that Windows displays a second monitor as the main monitor. If you want to keep the PC or laptop as your main monitor, go to “Settings” > “System” > “Display Device” and select the “Rearrange Display Devices” option. Then click on “Identify”. You should be able to see the assigned digit on each screen. If you wish to change the order, go to “Advanced display settings”.

As you begin working from home full-time, you will appreciate the value of having extra screen space. If you have an extra monitor or two, you can keep your applications accessible at any time.

This eliminates the need to switch between windows and alt-tab. Many desktop PCs can support multiple monitors. However, laptops aren"t likely to provide a similar solution.

However, did you know that a Windows laptop can support up to seven displays? In the following guide, we"ll show you how to set up multiple monitors on your work device.

The first thing you should do is to look at your computer. What ports do you have available? These are the most common display output slots you can work with: HDMI, USB-C, and miniDP.

When you have any one of these, your next step would be to choose a monitor supporting what you have. Most displays support HDMI, while newer ones have USB-C cables. MiniDP and DisplayPort technology, meanwhile, are usually found on Pro-level monitors.

It is pretty straightforward to add an extra display. All you need is to set up your new monitor, make sure it has the correct connection adapter, and plug it in. After that, your Windows laptop should detect it and start displaying your desktop automatically.

All you have to do is to right-click on your desktop and choose Display Settings. You will see two boxes in the new window that will open representing your monitors.

Click Identify to know which number corresponds to which screen. You can also rearrange the boxes so to match the physical arrangement of your displays.

Sometimes, when you do these, the computer will ask if you want to Keep changes or Revert. Click on Keep changes if you"re happy with it or Revert if you want to go back to the way it was.

Firstly, you need to find out what other ports you have available on your Windows laptop. Are there any spare HDMI or miniDP ports? If you do, you"re in luck! All you have to do is get a new display compatible with your available port, and you"re ready to go.

But if all you have is an extra USB-C port, you have to check if it supports transmitting a video signal. You can look at this table Kensington made to see if you can plug a monitor into your USB-C outlet.

The rule of thumb is if you see a Thunderbolt or DisplayPort logo beside the USB-C port, then it will work with a screen. All you need is a proper USB-C to HDMI or USB-C to DisplayPort/miniDP cable.

But if you don"t see any of the above logos beside your USB-C port, you can check your laptop"s manual. You can also contact your laptop"s maker and ask if it will support a video signal. If they say that it doesn"t support any display protocol, I"m afraid you can"t connect a monitor via that port.

If you don"t have an extra video port and absolutely need to have that extra monitor, get a USB 3.0 to HDMI adapter. It will be able to display your screen at full resolution, depending on the adapter.

If you find two external displays lacking, you can use your laptop screen as a third monitor. Use the same procedure we described above, and you"ll be good to go.

If you have existing or want to use HDMI monitors, I recommend going for the MST hub. This plugs into your DP-compatible port and then splits the signal into up to 4 distinct monitors.

These hubs come in either DisplayPort or HDMI outputs. Thus, allowing you to use HDMI monitors in your setup. The advantage you get in this method is you can use more affordable HDMI monitors. However, it will also limit you to a maximum of four displays.

Your other option is to use MST-compatible monitors only. These displays connect via a daisy-chain configuration. This would allow you to have up to seven screens on a single port.

One downside to this is that these displays are few and far between. Furthermore, they are far more expensive than their non-MST counterparts. This is because they tend to be considered professional displays. That is why they typically have enhanced features such as color accuracy.

Also, take note that your laptop must have a discrete graphics card with more than three external displays. This is because most built-in graphics usually supports up to three displays only. You should check your laptop"s specific model before committing to any purchase.

Now, whether you choose the MST hub or the daisy-chain method, setting up your monitors is easy. You only need to plug and play, and you"re ready to go. Automatic detection of these screens works well in Windows.

Go to the Display Settings menu to change the monitor placement. Then, scroll back up to the Using Your Laptop Screen as a Second Monitor section and follow my instructions for each display.

Multiple displays aren"t just for bragging or a conversation piece. You can use it at work to improve your quality of life. In addition, it will increase your productivity. Additionally, it will be a great entertainment and gaming rig.

A dual monitor setup isn"t always plug-and-play. Extending your screen to a second or third monitor requires a suitable graphics card with sufficient ports. This is particularly challenging if you"d like to add more than one external screen to your laptop.

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:

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.

Typically, if your computer has two ports on it, the video card should be capable of sending an output signal to both. If there"s only one port, then it probably can"t. However, your desktop might have available slots for additional video cards. So, even if there"s only one port on your desktop, don"t hesitate to pop the cover and check for any 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), into a docking station that features two or more ports. 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.

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.

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 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.

If you"re still not certain whether your computer can support dual monitors, another option is to research your graphics card. First, look up the brand of your graphics card.

Head to Google and research the brand of your graphics adapter, followed by the word "multi-display" or "multi-monitor." Hopefully, you"ll be able to find some evidence of whether your graphics card can handle multiple monitors.

If your laptop or PC has a DisplayPort, then you might be able to take advantage of what"s called multi-stream transport (MST) to daisy-chain two monitors off the single DisplayPort. These are the requirements:

Now, in the Display Settings screen, you should see both monitors detected. You can arrange them to either mirror or extend your desktop. There is also the option to split an HDMI signal to multiple monitors.

A docking station is a great way to add additional ports to your laptop, including ports for external monitors. The Anker PowerExpand Elite 13-In-1 Thunderbolt 3 Dock, for example, lets you hook up two 4K 60Hz monitors using its Thunderbolt 3 and HDMI ports. By using a splitter on your Windows laptop, you could even connect a total of three 4K monitors. Other laptop docking stations feature similar options.

Even if your PC or laptop graphics card only supports a single output port, you can still extend your system with a second display using a USB-powered monitor and DisplayLink software. Find an external display that"s USB-powered, plug it in, and install free DisplayLink software to make it all work.

Whichever approach you take to set up a dual monitor setup, you configure it all under Settings (press Windows + I) > System > Display. The example above is a laptop connected to an external monitor using the HDMI port on a USB-C dock.

To determine where your mouse can cross over from one monitor to the next, drag the squares representing your monitors around to rearrange them. Click Apply to save your changes.

To display different things on two or more displays, you need to extend your screen to the other monitors. Under Settings > System > Display, scroll down to Multiple displays and select Extend these displays.

If you want to close your laptop"s lid, but still use your external monitor, for example, to watch a movie, you have to change your laptop"s power options, which are hidden in the Windows 10 Control Panel.

If you want to use your external monitor, select Do nothing next to When I close the lid. Note that you can have different settings, depending on whether your laptop is running on battery or is plugged in.

As you can see, there are a lot of steps in the process where some people would give up and conclude that it just doesn"t work. If that"s still you, consider getting a larger monitor.

But really, it comes down to just making sure your video card is capable of doing this, and then playing around with those display settings and making sure that the monitors are configured correctly. If you have one DisplayPort, consider the daisy-chain option. And if all else fails, buy a USB monitor and install DisplayLink software.

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.

1) Plug thecable 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.

Trying to boost your productivity with a second screen? Want more immersive gaming sessions? Multiple monitors can help. Dual displays are great for multitasking and are easy to set up, but there are a few things to consider before you wade into a multiscreen world—whether you"re on Windows or Mac.

Windows: The presence of several ports on your graphics card indicates it can likely handle multiple monitors. But you should check the maximum number of supported displays and resolutions. (You can see what graphics card you have by typing Device Manager into the Search bar, opening it, and then expanding Display adapters.) Visit the manufacturer’s website to find the specifications for your graphics card, and look for a section titled Display Support or something similar that will list this info.

Mac: If you"re adding monitors to a Mac, click on the Apple icon > About This Mac and double-click your serial number, then tap Command-C on your keyboard to copy it, go to Apple"s website, and paste it into search. Click on Support to find the Technical Specifications and search for Video Support.

You can mix and match the types of screens you have at your workstation, though you"ll likely want some consistency. The most common monitor size is 24 inches, but 27-inch screens are increasingly popular. Having the same size screens will be nice for symmetry. Just keep an eye on resolution when you buy. A 1080p screen on a 27-inch monitor might look too fuzzy.

We dive into orientation and arrangements below, but consider different types of screen arrangements. My current preference is a 34-inch ultrawide screen paired with a 27-inch screen in portrait orientation. As the name suggests, ultrawides are really wide and can deliver the experience of two screens, minus the screen"s bezel in between. Pairing it with a screen in portrait mode means you get enough space on the ultrawide to run two full-size browser windows side by side, plus a vertical screen on the side for apps that benefit from it, like Slack and email.

Monitors come with a wide assortment stand designs. If you are going with the stand that comes in the box, check the measurements on the product page to ensure it"ll fit nicely on your desk.

Alternatively, you can mount your screen to your desk and get rid of the stand, freeing up a lot of space. (You can also freely move your screen to various angles and positions.) Many displays support the VESA mount system. There are different sizes, and monitor arms have a screen size range and maximum weight they can support. Always check whether the monitor"s product page mentions VESA support, and note the VESA mount size. When you buy an arm mount, make sure it supports the screen size and weight of your new screen.

To get the most from your computer and monitors, you"ll need to think about which ports and cables to use. For Windows PCs, your choice is often HDMI vs. DisplayPort. Unfortunately, this isn’t as straightforward as you might expect. There are several versions of each connection type, each with different capabilities. For example, HDMI 2.1 supports up to 8K resolution at 120 Hz, DisplayPort 1.4 can deliver 8K at 60 Hz, and HDMI 2.0 is limited to 4K at 60 Hz.

For laptops, you might be looking at Thunderbolt, Mini DisplayPort, or even USB-C. Sometimes you will need an adapter or USB hub to connect an external monitor.

Check the technical specifications for your graphics card and monitor to find the best option for you. Remember that the card, monitor, and cable (and any adapters) you use must support the same technology and the same version. High-end monitors usually come with a selection of cables in the box, but some manufacturers annoyingly provide a single option that might not match the monitor’s top capability.

Tip:If you"re using a wireless display adapter, connect to an HDMI port on newer TVs, then wirelessly connect your PC to it. After connecting your wireless display adapter to your TV, go to your Windows 11 PC, press Windows logo key + K to open Cast, then select your wireless display adapter.

To see which number corresponds to a display, select Start, then search for settings. Select Settings > System > Display> Identify. A number appears on the screen of the display it"s assigned to.

If you have multiple displays, you can change how they"re arranged. This is helpful if you want your displays to match how they"re set up in your home or office. In Display settings, select and drag the display to where you want. Do this with all the displays you want to move. When you"re happy with the layout, select Apply. Test your new layout by moving your mouse pointer across the different displays to make sure it works like you expect.

After you"re connected to your external displays, you can change settings like your resolution, screen layout, and more. To see available options, in Settings, select System > Display.

Windows will recommend an orientation for your screen. To change it in Display settings, under Scale & layout, choose your preferred Display orientation. If you change the orientation of a monitor, you"ll also need to physically rotate the screen. For example, you"d rotate your external display to use it in portrait instead of landscape.

Make sure the video cable is securely plugged into your external display or TV. On the other end, make sure the video cable is securely plugged into the adapter.

Disconnect the adapter from your Surface, and then reconnect it. If that doesn’t work, disconnect the video cable from your adapter, and then reconnect it.

If you travel with a laptop and iPad, you need this app. I needed a second screen, but Duet gives me even more. Full gesture support, customizable shortcuts, Touch Bar, tons of resolution options, and very little battery power. How is this all in one app?

Co-workers can’t believe I can share my desktop on my iPad and my iPhone. Look no further. This is a terrific addition to any office, remote or otherwise.

With the new Air feature that allows remote access to a laptop or desktop computer from anywhere in the world (with internet access), this app has become even more essential.

I just love this app. Especially when I am travelling for work an working from the company branches. Then I use my iPad as second monitor for Outlook, Lync and other chat while I use the laptop big screen for remote desktop to my workstation at the main office. :)

As head of an NGO, I travel a great deal to remote places around the world. It is very difficult to be productive, as power and internet availability are often a challenge. However when I am able to set up, Duet works like charm to improve productivity.

A second screen is great for PowerPoint Presenter View or for being more efficient at getting work done. If you don’t have a monitor to plug into your Windows or Mac laptop as a second screen but you have a second Windows or Mac laptop, you can do it. You can use a video capture device that costs around $25 to use the second laptop as a second screen for your primary laptop.

This works between any combination of Windows or Mac laptops. The laptops don’t need to be recent ones, even older ones will work just fine. If you are visiting a friend even their laptop or desktop computer will work. All you need is a USB port on the second laptop.

One end has an HDMI input that takes the video signal from the primary laptop. The other end has a USB plug that connects to the second laptop and tells the laptop it is a camera that is providing a video feed. The video capture card I use is on Amazon at https://amzn.to/3IZQGX4.

To connect the two laptops, attach an HDMI cable to the primary laptop as you would for any external monitor. With many laptops not having HDMI ports anymore, this will likely include using an adapter from a mini-DisplayPort or USB-C port. Connect the HDMI cable to the Video Capture device. Plug the video capture device into an open USB port on the second laptop. You may need an adapter if the second laptop only has USB-C ports. Here what the setup looks like.

On the primary laptop, go into the display settings and make sure that the laptop is extending its desktop to the second screen. You can also move the second screen so that the displays are arranged the same as the laptops are positioned on the desk. You may also have to adjust the resolution of the second display if the default has been selected incorrectly.

On the second laptop, use an app that displays the camera on the laptop screen in order to see the second screen from the primary computer. In Windows the easiest app to use is the built-in Camera app. Make the app full screen in order to see everything bigger. On the Mac I suggest downloading the Quick Camera app from the App Store because it shows the camera without any user interface covering up portions of the camera feed. The app will likely display the default webcam from the second laptop but you can change which camera is displayed.

On your primary laptop, you now have a second screen that you can use just as if there was a second monitor attached. Use it for Presenter View in PowerPoint, share it in a virtual meeting on Teams or Zoom, or use it to have multiple apps open while you are working. The OS sees it just like a monitor so anything you would use a monitor for you can use this second screen for.

When you are done, just close the display app on the second laptop and disconnect the cables and video capture device. This gives you an easy-to-use option for a second screen when travelling or working in different locations.

In this video I show you how to connect the two laptops using the video capture device and use the second screen from the primary laptop. I show a Windows laptop as a second screen for a Windows laptop, a Mac laptop as a second screen for a Windows laptop, and a Windows laptop as a second screen for a Mac laptop.

Connect your display to power, then connect your display to your Mac. Check the ports on your Mac to find out whether you need an adapter. If you"re using a USB-C or Thunderbolt adapter to connect your display, the adapter must be compliant with DisplayPort Alt Mode, Thunderbolt 3, or Thunderbolt 4.

If you use an external keyboard and mouse with your Mac notebook, you can close the built-in display after you connect your external display. You might have to press a key or click your mouse to wake the external display. To use your Mac with the display closed, you need to connect your power adapter or connect an external display that also charges your Mac, such as the Apple Studio Display or 23.7-inch LG UltraFine 4K Display.

It is such a waste to only use the LCD for desktop computers. Connecting it up with a laptop PC has many merits for the user and can also bring out the latent power of the laptop.

Note: Below is the translation from the Japanese of the ITmedia article "The dual display in Windows 7 is now even more convenient" published March 1, 2010. Copyright 2011 ITmedia Inc. All Rights Reserved.

Most laptops have a handy "external display output" port. It can be used in the home to transmit videos played on the laptop to a large screen TV or, in the office, to connect up with a projector for presentations. In fact, there must be many users who already use it like this. However, people tend to use just the laptop in their daily routine and there are probably not so many cases where they use the external display output.

A laptop can be put to more effective use if it is connected to an external LCD. The photograph shows an EIZO 23-inch wide-screen LCD connected by HDMI to a Sony VAIO C laptop (VPCCW28FJ/R).

This time we would like to suggest a style that can be used in both the home and the office, where a laptop and stand-alone LCD remain connected. A laptop already has an LCD, but using it with an additional stand-alone LCD offers various merits. Not only does it make the laptop environment more pleasant and convenient, it also expands the potential of the computer itself, for example by making it possible to use it for new purposes.

Even if the LCD is already connected to a desktop computer and being used for something other than the laptop, most monitors nowadays have two or more video inputs and they tend not to use this capability to the full. It is such a waste to let the laptop"s external display output function and the monitor"s video input function remain dormant, so we would like them to be put to effective use. Of course, we would also recommend the introduction of a new LCD to connect to your laptop.

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.

Another plus is that you can create the luxury of a "watching while" environment where you run the web browser, for instance, on the laptop"s built-in LCD and watch the video content on the large screen of the external monitor. This can be really useful for hobbies too. For example, while playing a game on the large external LCD screen you can check out strategies on websites, post information on a BBS or communicate with other users.

You can smoothly use multiple applications at the same time in the large workspace provided by a dual display. The photograph shows an EIZO 24.1-inch wide-screen LCD, the FlexScan SX2462W connected to a VAIO C. By supplementing the laptop"s built-in 1366 × 768 dot 14-inch wide-screen LCD with a 1920 × 1200 dot 24.1-inch wide-screen, it is possible to show more data at a time, a huge boost to work efficiency.

With two screens it"s easy to have full-screen display of the video content on one screen while you operate the computer on the other. The photograph shows an EIZO 23-inch wide-screen LCD monitor connected to a VAIO C. The VAIO C has HDMI output and the LCD monitor has HDMI input so visuals and sound can be transmitted by a single HDMI cable. The LCD monitor has full HD screen resolution (1920 × 1080 dot), making it the perfect match for HD video content.

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.

When holding small meetings it is certainly very convenient to be able to offer simple explanations of the presentation materials displayed on the external LCD, rather than having to ready a projector. Being able to explain about what is displayed on the screen means fewer documents to distribute, helping your office to "go paperless", which can only be a good thing.

We would like to point out here that you should check in advance the maximum resolution that the laptop"s external display output can handle. This can be found in documents such as the laptop"s specifications chart and support information. This is because, although most laptops can handle output up to 1920 × 1080 dots or 1920 × 1200 dots, some slightly older computers have an upper limit of 1680 × 1050 dots or 1600 × 1200 dots.

Even if the upper limit is 1680 × 1050 dots, the LCD can still display the data if its own resolution is 1680 × 1050 dots or higher. In such cases, it is better to use a monitor that offers dot-by-dot display, which displays the input resolution as it is, or enlarged display, which maintains the screen"s aspect ratio as it is. You do not need to worry because EIZO wide-screen LCDs can handle such display methods (although in some cases they do not function properly depending on the laptop computer or input resolution).

This is an example of a low-resolution display on the 1920 × 1200 dot display SX2462W. Since dot-by-dot display outputs the physical "1 dot" of the LCD and the input resolution "1 dot" without enlargement or reduction, it is shown small in the center of the screen (photo on the left). The display is a little blurred if it is enlarged while maintaining the aspect ratio, but this method is suitable for displaying images as they are shown large with low resolution to make the most of the screen size (photo on the right). Many monitors that cannot handle such display methods enlarge the display to full screen regardless of the input resolution. In such cases you have to be careful as the aspect ratio of the image is altered (for example, people appear to be thinner or fatter).

It is easy to set up a dual display in Windows 7. A menu is displayed when you right-click on the desktop. From "Screen resolution" it is possible to detect and align the external LCD, and set details such as resolution, display method and which will be the main display screen.

The "Screen resolution" menu. If the external LCD is not automatically recognized, click on "Detect". After the monitor has been recognized, you can select the display mode from the "Multiple displays" drop-down menu. Select "Extend display screen" to make the laptop screen and the external LCD into a single display screen (dual display).

Select "Duplicate display screen" from the "Multiple displays" drop-down menu to display the same content on the laptop screen and the external LCD screen (clone view). With this drop-down menu you can also set it to display video on one of the LCDs.

You can also call up a settings menu to decide the display method for a projector or external display by pressing the "Windows" and "P" keys. This is a tip worth remembering as selecting "Extension" for dual display or "Duplicate" for clone view here allows you to switch swiftly between them as necessary.

It is also worth noting that Windows 7 has added functions so that dual display can be used more effectively. An active window can be moved to the screen of another LCD by simultaneously pushing "Windows" + "Shift" + "→" (or "←"). It is also possible to maximize the window by pressing "Windows" + "↑", minimize it by pressing "Windows" + "↓", and shift it to the left or right of each screen by pressing "Windows" + "→" (or "←"). Making good use of these shortcuts should enable the efficient placing of windows in the two screens.

In Windows 7, pressing "Windows" + "Shift" + "→" instantly moves the active window from the left-hand screen (photo on the left) to the right-hand screen (photo on the right). Conversely, you can move the active window from the right-hand screen to the left-hand one by pressing "Windows" + "Shift" + "←".

We would recommend a wide-screen model with a screen resolution of 1920 × 1080 dots (Full HD) or 1920 × 1200 dots (WUXGA) as the LCD to connect to a laptop, so that you can make full use of the advantages of dual display. EIZO has an extensive line up of wide-screen LCDs which can offer many benefits, in addition to the merits of a large screen and high resolution, when used with a laptop for dual display.

One such feature is the flexible stand adjustment. For example, the tilt, swivel and height can be adjusted for the FlexScan SX2462W, a 24.1-inch WUXGA model, and the FlexScan EV2333, a 23-inch full HD model. This enables users to adjust the screen position for easy viewing according to their own posture, which not only boosts work efficiency but also reduces physical strain.

The SX2462W stand. The simultaneous adjustment of its tilt, swivel and height enables the optimum screen position to be aligned for its operating environment.

The SX2462W is also equipped with vertical display function, turning the screen through 90 degrees. Vertical display is really handy when viewing elongated documents, graphics or web pages. In addition, when used as a standard horizontal screen, a 24.1 wide-screen, with its 518.4 × 324.0 mm display area, can display two A4 sheets, in other words one A3 (420 × 297 mm) in actual size. As well as being very useful in areas such as graphics or desk top publishing, this is also bound to come in handy when checking large business or accounting documents.

Setting the connected monitor into a vertical position is very convenient when displaying elongated web pages and documents or photographs that were taken vertically

With a 24.1 inch wide-screen like the SX2462W, an A3 sheet (two A4 sheets side by side) can be viewed in actual size, particularly effective for paper-based creative work ITmedia LCD Course II, Lesson 3: Which is better, 16:10 or 16:9 ? – "Screen size / resolution / aspect ratio"

We must not forget that EIZO"s wide-screen LCDs have non-glare screens (processed to reduce ambient light reflection). Nowadays the trend is for laptops to have an LCD with glare (glossy) surface treatment. While these can display images in bright color, reflected ambient light can sometimes be distracting.

A laptop screen is not so large and adjusting its angle can avoid the reflection of lights and so on, however it is not so easy with the large screen of an external LCD. When it comes to the large screen of an LCD in habitual use, a non-glare type that is not reflective is probably easier to see, as well as being kinder on the eyes. A large screen, high resolution and non-glare ensure that you can comfortably continue viewing over a prolonged period of time.

The surface treatment of an LCD makes a difference to the background reflection. Glare panels do not diffuse background light, making it easier to achieve high color purity, but easily reflect the user or lights (photo on the left). If the lights are similarly trained on a non-glare panel they do not have much effect, only appearing as a fuzzy brightness (photo on the right).

Another distinctive feature of EIZO wide-screen LCDs is a commitment to energy saving. They incorporate various power saving features that support "EcoView". A pivotal feature is the "EcoView Sense" adopted in the FlexScan EV series, such as the EV2333W.

This is the motion sensor on the front of the LCD. It constantly monitors the user"s movements to automatically take finely-tuned power saving measures. To be more precise, if the user"s presence is not detected for a specified period of time, for example if he leaves his seat, the monitor automatically switches to power save mode, and then automatically switches back when the user"s presence is detected again.

Other features include "Auto EcoView", which automatically optimizes the brightness of the LCD based on ambient lighting, and "EcoView Index", which displays a meter on the screen showing how much power is being saved. All these features can be expected to have a strong energy saving effect and to boost the user"s awareness of power saving, making them particularly useful in the office.

A standard laptop computer switches to sleep mode if the built-in LCD is closed while it is running but, if this function is turned off, a laptop can be treated as a "small desktop computer."

It can be set to use only the connected external LCD and not to react when the laptop"s built-in LCD is closed. The transformation into a small desktop PC is complete if you add a keyboard and mouse connected to the laptop via USB ports, for example. The OS is still running even though the laptop"s built-in LCD is closed, so you can carry out normal operations using the external keyboard and mouse, and also use the laptop"s built-in optical drives.

The idea is to use a large screen, high resolution external LCD at home or in the office, and to use the laptop"s built-in LCD as usual for mobile purposes. This helps to boost the longevity of the laptop"s built-in LCD and many people do use their laptop in this way. If you feel reluctant to use a dual display environment, where the screen is split in two, why not give this a try?

Select "Only show the desktop on 2" from the "Multiple displays" list in the "Screen resolution" menu. The laptop"s built-in LCD will be switched off and the external LCD will become the main display.

In the case of Windows 7, open "Alter power button operation" from the "Power options" list in the Control Panel"s "Hardware and sound", and alter the "Operation when the cover is closed" to "Do nothing".

By making this simple setting your laptop can be used as a space saving desktop computer. Another plus is that the laptop"s built-in LCD will last longer.

Recently some high-end laptop computers, such as the Sony VAIO F, are insisting on good display quality for their LCDs. However, a typical laptop"s built-in LCD does not have as good image quality as a stand-alone LCD. This is only natural since the costs allowed for display quality are completely different for an LCD incorporated into the PC as one of its parts and a specialized LCD.

However, by using an EIZO wide-screen LCD a laptop user can still fully enjoy such benefits of a stand-alone high-quality LCD as excellent color reproduction, a wide viewing angle, more even display and a wealth of items that can be adjusted to improve image quality. This is a crucial point for people who use their computer for photographs and videos in particular.

EIZO"s wide-screen LCDs emphasize color reproduction, and the coloration in sRGB mode has a high degree of accuracy. The standard color gamut used in PC environments and Internet content is sRGB, so you need have no worries about viewing or editing videos and photographs. They can also display images on web pages, such as products in online shops or goods for sale in online auctions, in colors that are very close to the real thing. (This is also influenced by how the seller took the photographs and processed the images, so we cannot say that the colors will always be accurate.)

Furthermore, in addition to sRGB color gamut accuracy, the high resolution-oriented FlexScan SX has the added benefit of covering more than 95% of Adobe RGB. Adobe RGB is a color gamut whose definitions encompass more highly-saturated colors than sRGB. In other words, it can represent a larger number of colors and brighter hues than sRGB.

Adobe RGB is the de facto standard in the publishing field and, closer to home, is used in digital SLR cameras and high grade compact digital cameras. The FlexScan SX series can reproduce the colors of photos taken in Adobe RGB mode with almost perfect accuracy on the screen. Retouching photographs proceeds more efficiently since subtle differences in color can be checked on the screen.

An example of sRGB color gamut image data displayed on a standard laptop and on the SX2462W. The SX2462W"s reproducibility of sRGB mode is of a considerably high standard but the color balance on the laptop has been lost. This would make it difficult to perform rigorous photo retouching.

In this case, if the image is edited on the external LCD with its high color reproducibility and the many tool palettes in the application are grouped in the laptop"s built-in LCD, there is less need to display or hide the tool palettes or to switch back and forth, and the image data to be edited can be displayed in a large form, making for more efficient work.

In this case, if the image is edited on the external LCD with its high color reproducibility and the many tool palettes in the application are grouped in the laptop"s built-in LCD, there is less need to display or hide the tool palettes or to switch back and forth, and the image data to be edited can be displayed in a large form, making for more efficient work.

When doing things like photo retouching, using software where there is a lot of switching between tool palettes it is very handy to display the image data to be edited on the external LCD with its high color reproducibility, and to gather the palette tools to be used on the laptop"s built-in LCD.

Going back to the subject of laptop computers, it is not going too far to say that applications and functions are being spoiled in laptops whose built-in LCD"s image quality is not too good. Connecting a laptop to a monitor with high image quality dispels any concerns about work that deals with colors and also helps to bring out the laptop"s potential.

Combining an EIZO wide-screen LCD with a laptop computer makes viewing videos and images even more fun. Just being able to see them on a large screen is a pleasure, but what makes it even better is that our LCDs are equipped with Fine Contrast, the optimum image quality mode for video and visuals. You can also use the Custom mode to create the image quality you prefer.

We expect that you now understand how displaying screens from a laptop computer on a stand-alone LCD can create a very pleasant environment. It feels as if your everyday laptop has been transformed into a completely different desktop machine. Even if you only use laptop computers, it is definitely worthwhile to add a stand-alone LCD.

When choosing the type of LCD the most important consideration is to choose one with overall high quality. When it comes to that, we can recommend EIZO wide-screen LCDs to a broad range of laptop users. In addition to their high image quality, EIZO wide-screen LCD are built with careful attention to detail, including non-glare screens, versatile stand features, dot-by-dot capability, abundant image quality modes, and our proprietary eco-functions. We want you to make full use of your beloved laptop computer along with an EIZO wide-screen LCD.

This time we have spoken about how an external LCD can be connected to a laptop computer, but if your main machine is a desktop computer then you probably already have a LCD.

In which case, why not consider adding a full HD (1920 × 1080 dot) or WUXGA (1920 × 1200 dot) wide-screen LCD and creating a more advanced dual display environment to further enhance your computer"s usability.

The dual display environment of a desktop PC has a wider range of options than a laptop computer, which is already installed with an LCD. Depending on the combination of products used you can seek for a larger screen, higher resolution and better image quality.

The photograph below shows two EIZO 24.1-inch WUXGA (1920 × 1200 dot) models being used side by side for an overwhelming super high resolution of 3840 × 1200 dots in total.

You can get a super high resolution of 3840 × 1200 dots in total by putting two 24.1-inch 1920 × 1200 dot wide-screen LCDs side by side. The advantage in this is that a larger screen and higher resolution are achieved at a lower cost than buying a single 30-inch high resolution model

Splitters are supported in DisplayPort connections, for example, which will allow you to use one port on the laptop to connect a number of monitors, although this isn’t a very economical way to do it since it might be a bit expensive.

You might find that occasionally monitors will have an additional port to allow you to connect the signal from your device to each monitor by “daisy chaining” from one monitor to the next, although it’s worth pointing out this isn’t very common.

Alternatively, if you have a hub or a laptop with a DVI, USB-C, Displayport, and HDMI, feel free to mix and match the monitors. Do bear in mind that you’ll need to select the best input for each monitor’s specification so that you get the best refresh rate and resolution out of each one. This is known as the “all-hands-on-deck” strategy.

If you"re in the market for a new laptop, be sure to have a look at our best business laptops guide, as we always value devices with plenty of connectivity options.

As technology continues to progress and new standards are created, it’s becoming more frequent to find difficulties in achieving the result you want. This also applies to monitors. The everyday, casual, user might not be familiar with USB-C, Displayport, or HDMI, and it’s not always clear for them. Usually, a task which should essentially be “plug this into this” becomes complex and time consuming. However, don’t let this dissuade you from accomplishing your monitor goal, just make sure you do plenty of research before buying a cable, and make sure it’s the one you need. Once you’ve overcome this, the rest is more or less quite straightforward.

DisplayPort is a new digital standard for connecting monitors to computers and has the capability to provide a scalable digital display interface with optional audio and High-Definition Content Protection (HDCP) capability. DisplayPorts usually resemble USB Ports with one side angled. A DisplayPort cable should be used if DisplayPort connectors are available on both the computer and the monitor.

Digital Video Interface (DVI) is the digital standard for connecting monitors to computers. DVI connections are usually color-coded with white plastic and labels.

DVI cables provide a higher quality signal than VGA cables. A DVI cable should be used if DVI connectors are available on both the computer and the monitor.

Video Graphics Array (VGA) is the analog standard for connecting monitors to computers. VGA connections are commonly color-coded with blue plastic and labels.

HDMI cables provide the same quality of video signal as DVI. However HDMI can provide sound through the cable, but the video card has to support the audio through the HDMI function in order for it to work.

​This option is recommended when an external monitor is connected to a laptop, and each monitor can display a different screen independently to improve your convenience. The relative position of the screens can be set up here; for example, monitor 1 may be set up to be to the left of monitor 2 or vice versa. This depends on the physical position of the LCD monitor in relation to the laptop. The horizontal line displayed on both monitors can be based on the laptop or external monitor. These are all adjustable options, and the only thing you need to do is drag the monitor of the main screen to the extended monitor.

This option is typically chosen when you want to use the laptop as a PC and enjoy one large, external monitor instead of multiple monitors. Most current laptops support mainstream resolutions. As shown in the figure above, the resolution of the laptop monitor is only 1280 x 800, but after connecting a 27-inch external LCD monitor, you can immediately improve your visual enjoyment to 1920 x 1080 full HD quality.
