connecting two lcd monitors one pc supplier

Even a generous 27-inch monitor can feel cramped when you’ve got multiple windows open on your desktop (and who doesn’t?). It’s much worse if you’re stuck on a tiny laptop screen. Fortunately, it’s simple enough to add a second monitor to your PC setup and stretch your legs... I mean eyes. You know what I mean.

Today’s monitors typically come with some combination of VGA, DVI, HDMI, and DisplayPort ports. In other words, you’ll have a couple of options for how to connect the monitor to your PC. While it is common for VGA and DVI cables to come included with the display, you may have to purchase your HDMI or DisplayPort cable separately.

Step 4: Choose the primary display. The Make this my main displayoption controls which monitor gets the taskbar and Start button. If you don’t see that option, the currently selected monitor is already the main one.

For example, you can connect a monitor that only has a DVI port to a computer that only has an HDMI port. In this case, the cable has one end with a DVI connection and the other end with an HDMI port.

Sometimes you have only one HDMI port on your computer (typically on a laptop), but need two ports so that you can connect 2 external monitors. In this case:

Extend the display: with that option, you can spread your applications windows on the two different screens. Typically, Document Control professionals use that option,

If you have a desktop computer, it is likely that you will have different display ports on the computer (for example either several HDMI ports, or one HDMI port and one VGA port). If your monitor

When you work with a lot of documents at once, or find yourself with a lot of windows open, it can become welcome, if not necessary, to have more display room for your work all at once on your computer. Rather than buy a single, larger monitor, you can use a second one to display either the same or different windows.

For laptops where you intend to use the built-in display as one of your monitors, you only need one place to plug in the second monitor on the laptop.

Adding another monitor adds, at minimum, two more cables to your computer setup. Please be sure these cables will not be caught or snagged by your chair, desk, or people walking by.

VGA: VGA ports are usually blue and rectangular with 15 holes. They usually have screw holes on the side used to secure the VGA cable. VGA is used on old computers. Most newer monitors do not support a VGA connection. However, you can connect a VGA to a newer monitor using an HDMI-to-VGA adapter.

DVI: DVI ports are usually white with 24 holes. They also have a slot with 4 additional holes to the right. Like VGA ports, they often have screw holes on the sides to secure the DVI cable. DVI is another legacy video connection that is mostly used on older computers and monitors. It supports a higher resolution than VGA, but it does not support modern HD or 4K displays. Like VGA, most newer monitors do not support DVI, but you can connect a DVI connection to a newer monitor using a DVI-to-HDMI adapter.

DisplayPort: DisplayPort output ports are thin and rectangular-shaped with the bottom-right corner cut. Some laptops may use a mini-DisplayPort connection, which is the same shape as a DisplayPort, but smaller. DisplayPort is a newer display connection mostly used with computer monitors rather than televisions. DisplayPort supports AMD"s FreeSync and Nvidia"s G-Sync. DisplayPort 1.2 can support 4K at 60 frames-per-second. DisplayPort 1.3 can support 4K at 120 frames-per-second. DisplayPort 1.4 can support 8K at 60 frames-per-second and HDR. DisplayPort 2.0 supports up to 16K at 60 frames-per-second. A DisplayPort connection has the ability to support multiple monitors connected together from a single DisplayPort connection.

In an office, it"s common to see people using multiple monitors at the same computer. It"s a great way to expand your workspace and use lots of different apps at once.

Luckily, dual monitors aren"t just for professionals. You can set up dual monitors on your PC and Mac easily. You just need the monitors and cables to connect them.Important: You can set up dual monitors on a laptop, too. The laptop"s screen will just count as one of the monitors.

William Antonelli/InsiderQuick tip: You can also get to your Display settingson Windows by going to Settings > Ease of access > Display, and then click on the Additional display settingslink in the Related settingssection.

3.Scroll down to the Multiple Displays section, open the drop-down menu, and choose how you want the dual monitors to work. Here are your options:Extend these displays: You can set your screens up so that they display different things and your mouse cursor can move between them.

6.Click on the second display in the left sidebar, and set the Use asdropdown to one of the following options:Extended display: This will allow you to display different things on the screens. That means you can, for example, have Finder open on one screen while browsing Google Chrome on the other.

Stefan Ionescu/InsiderNote: If you want to use an iPad as a second monitor for your Mac, you"ll have to use the Sidecar feature. Check out our article on the feature for tips on setting it up.

The short answer is yes – an HDMI splitter will work in a dual monitor setup. However, it"s important to note that the device will only split the signal between the added monitors. That means both monitors will mirror what is being displayed on your computer"s screen.William Antonelli

Determine the type of video connectors that are available on your computer and the monitors. The number of video connectors depends on the type of graphics card that is installed in your computer. Most graphics or video cards on a desktop computer can support two or more monitors depending on the graphics card and computer specifications. However, laptops can support up to two monitors depending on the computer specifications. To learn more, see the Dell Knowledge Base article How to Connect a Monitor to a Dell Computer.

Once the cables are connected securely, your computer should automatically detect and display the desktop screen on the connected monitors. You can now select the display style that best suits your needs.

Microsoft Windows provides multiple display style options on how the desktop screen is displayed across multiple monitors that are connected to your computer.

Extend - Stretch the desktop across the two displays. The desktop screen of your computer is extended across all the detected monitors and allows you to have a desktop screen that spans across all monitors.

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:

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.

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.

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.

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.

If you’re able to use one external monitor, but have issues using more than one, it’s possible that your display adapter (also called a graphics card) can’t support more than one monitor. For information on how many monitors your display adapter can support, contact its manufacturer.

Note:If you are trying to use a display splitter extend your display to more than one external monitor, you won"t be able to. The splitter is duplicating the same signal instead of creating two independent signals.

If your device only has one video output port, then by default, you can only support a single external monitor. You"ll need one of the following to support more than one external monitor:

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.

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.

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.

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.

Anyone who is used to working on a dual monitor setup will tell you how cramped working on a single monitor is—especially on a laptop or notebook. We’ll discuss how to replicate the office desktop PC experience at home by connecting additional displays to any business laptop PC.

The Thunderbolt 3 USB-C interface provides an all-in-one port and cable for high speed data transfers, high resolution video output, and battery charging. Laptop OEMs starting building business notebooks with Thunderbolt 3 connectivity in 2018 and is now more or less standard issue for new business notebooks.

A notebook with Thunderbolt 3 is powerful enough to display video to two daisy chained 4K-resolution displays, or one 5K screen. Note that you will need a Thunderbolt 3 input on the monitor you’re connecting, however. If you have Thunderbolt 3 / USB-C on your computer but not your monitor, you’ll find an easy fix with the appropriate video adapter (USB-C to HDMI or USB-C to VGA).

A laptop docking station offers remote workers a way to connect a laptop to multiple external displays and other peripherals if needed. The latest generation USB-C docking stations connect to a laptop’s USB-C port and delivers handy backwards compatibility to connect to older monitors with HDMI and DisplayPort inputs that new laptops may not support.

Laptops manufactured within the last eight years commonly have built-in HDMI video output. If you want to add one extra monitor, simply attach an HDMI cable to an HDMI-enabled computer. An inexpensive HDMI-DVI cable adapter will add compatibility to a monitor without a HDMI input.

Laptops that have only one HDMI video output will benefit from a USB 3.0 docking station for a dual monitor setup in addition to the laptop display. The HDMI standard does not support daisy chain monitor configurations. If you don’t want to purchase a docking station, a workaround for connecting a second monitor to laptop in lieu of docking station is to use a USB-to-HDMI adapter. Note that running video output from a USB connection tends to take a toll on computer resources and you may run into performance issues, especially for any tasks beyond basic web browsing or word processing.

DisplayPort video output can support two monitors without a docking station in a daisy chained configuration, providing functionality that HDMI cannot support. HDMI and DisplayPort are not compatible, and you will need monitors with a DisplayPort input. Converting a DisplayPort signal to HDMI using a passive adapter cable may work but is generally not a recommended solution.

Select Start> Settings> System> Display. Your PC should automatically detect your monitors and show your desktop. If you don’t see the monitors, selectDetect.
