Как подключить два монитора к компьютеру
Если вам потребовалось подключить два монитора к компьютеру или же второй монитор к ноутбуку — сделать это, как правило, совсем не сложно, за исключением редких случаев (когда у вас ПК с интегрированным видеоадаптером и единственным выходом на монитор).
В этой инструкции — подробно о подключении двух мониторов к компьютеру с Windows 10, 8 и Windows 7, настройке их работы и возможных нюансах, с которыми можно столкнуться при подключении. См. также: Как подключить телевизор к компьютеру, Как подключить ноутбук к телевизору.
Подключение второго монитора к видеокарте
Для того, чтобы подключить два монитора к компьютеру необходима видеокарта с более чем одни выходом для подключения монитора, а это практически все современные дискретные видеокарты NVIDIA и AMD. В случае ноутбуков — на них почти всегда присутствуют разъем HDMI, VGA или, с недавних пор — Thunderbolt 3 для подключения внешнего монитора.
При этом потребуется, чтобы выходы видеокарты были такими, которые поддерживает для входа ваш монитор, в противном случае могут потребоваться переходники. Например, если у вас два старых монитора, имеющих только VGA вход, а на видеокарте набор из HDMI, DisplayPort и DVI, вам пригодятся соответствующие адаптеры (хотя, возможно, более оптимальным решением здесь будет замена монитора).
Примечание: по моим наблюдениям некоторые начинающие пользователи не знают, что их монитор имеет больше входов, чем используется. Даже если ваш монитор подключен по VGA или DVI, обратите внимание, возможно на его тыльной стороне есть и другие входы, которые можно использовать, в таком случае придется просто приобрести необходимый кабель.
Таким образом, первоначальная задача — физически подключить два монитора, используя доступные выходы видеокарты и входы мониторов. Делать это лучше на выключенном компьютере, при этом разумным будет также выключить его из сети электропитания.
Если осуществить подключение невозможно (нет выходов, входов, адаптеров, кабелей) — стоит рассмотреть варианты приобретения подходящей для нашей задачи видеокарты или монитора с необходимым набором входов.
Настройка работы двух мониторов на компьютере с Windows 10, 8 и Windows 7
После включения компьютера с двумя подключенными к нему мониторами, они, после загрузки обычно определяются системой автоматически. Однако, может оказаться, что при первой загрузке изображение будет не на том мониторе, на который оно выводится обычно.
После первого запуска останется лишь настроить режим работы двух мониторов, при этом Windows поддерживает следующие режимы:
- Дублирование экрана — на обоих мониторах выводится одинаковое изображение. В данном случае, если физическое разрешение мониторов отличается, возможны проблемы в виде размытости изображения на одном из них, поскольку при дублировании экрана для обоих мониторов системой выставляется одинаковое разрешение (и изменить это не получится).
- Вывод изображения только на один из мониторов.
- Расширить экраны — при выборе данного варианта работы двух мониторов, рабочий стол Windows «расширяется» на два экрана, т.е. на втором мониторе находится продолжение рабочего стола.
Настройка режимов работы осуществляется в параметрах экрана Windows:
- В Windows 10 и 8 вы можете нажать клавиши Win+P (латинская P) для выбора режима работы мониторов. При выборе «Расширить» может оказаться, что рабочий стол «расширился не в ту сторону». В этом случае зайдите в Параметры — Система — Экран, выберите тот монитор, который физически находится слева и установите отметку «Сделать основным дисплеем».
- В Windows 7 (также возможно сделать и в Windows
зайдите в параметры разрешения экрана панели управления и в поле «Несколько дисплеев» установите нужный режим работы. При выборе «Расширить эти экраны» может получиться, что части рабочего стола «перепутаны» местами. В этом случае, выберите в параметрах дисплеев тот монитор, который физически находится слева и внизу нажмите «Сделать основным дисплеем».

Во всех случаях, если у вас возникают проблемы с четкостью изображения, убедитесь, что для каждого из мониторов установлено его физическое разрешение экрана (см. Как изменить разрешение экрана Windows 10, Как изменить разрешение экрана в Windows 7 и 8).
Дополнительная информация
В завершение — несколько дополнительных пунктов, которые могут быть полезны при подключении двух мониторов или просто для сведения.
На этом, думаю, можно завершить. Если же остались вопросы, что-то не понятно или не работает — оставляйте комментарии (по возможности, подробные), я постараюсь помочь.
These days many users has more than one monitor available. However, running a dual monitor in Windows 7 can be tricky to get working correctly. This tech-recipes tutorial will get you started. These directions are for Windows 7 although the directions for XP and Vista are very similar.
Connect Second Monitor
First things first, make sure your computer can support two monitors. The box will need the right outputs for dual monitors. If you use a higher end GPU which allows — you have multiple HDMI outputs; however, Windows 7 is smart enough to use outputs of different types. For example, if you computer has a DVI and VGA outputs, you still can get a dual setup working.
Connect the external monitor cable to the correct video port on your laptop or desktop computer. Most laptops have an external monitor connection which can be used as your second monitor.
Types of Video Connections
DisplayPort is a new digital standard for connecting monitors to computers; it usually resembles a USB port but one side has an angle. The DisplayPort cable should be used if DisplayPort is available on your laptop and the external 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. A DVI cable should be used if DVI connectors are available on your laptop and the external monitor.
Video Graphics Array (VGA) is the analog standard for connecting monitors to computers. VGA connections are usually color-coded with blue plastic and labels. A VGA cable should be used if DVI ports are not available on your laptop or the external monitor.
High-Definition Multimedia Interface (HDMI) is the current digital standard for connecting many kinds of video devices and provides the same quality video signal as DVI. HDMI can provide audio through the cable, but the video card installed in your computer must be capable of supporting the audio through HDMI in order for it to work properly. An HDMI cable should be used if HDMI ports are available on your computer and the external monitor.
Configure the Display Settings for Dual Monitor
In Windows 7, it is easy to add a second monitor by using the new hotkey Win+P. This is convenient when you need to change the display settings during your presentations with a projector connected to your laptop. Here are two methods to set up multiple monitors in Windows 7. Make sure that you connect the external monitors to your laptop or your desktop computer first.
Method 1: By keyboard shortcut «Win+P»
Press the Windows logo key + P on your keyboard. Select one of the following options according to your needs: (The screen shot for this step is listed below).
Select one of the following options:
- Computer only: This setting will show the screen image only on your laptop monitor.
- Duplicate: This setting will duplicate your laptop screen image on both monitors based on the monitor with the lower resolution.
- Extend: This setting allows you to move a window from one monitor to the other by clicking the Title Bar of the window and dragging the window to a new location.
- Projector only: This setting is typically chosen when your laptop is used as a desktop computer, so you can enjoy the higher resolution of a large external monitor.
Method 2: By the «Screen Resolution» menu
Right-click any empty area of your desktop, and then click Screen resolution. (The screen shot for this step is listed below). Click the Multiple displays drop-down list, and then select Extend these displays, or Duplicate these displays. Note If you cannot see the additional monitor(s) listed, click Detect.
After successfully connecting the second monitor, you can monkey with the resolution or orientation if you like, but you definitely need to choose how the multiple displays will operate. You’ve got four (really three) options:
- Duplicate these displays: This shows the same display on both monitors and can be handy in some situations, especially when you’re giving presentations.
- Extend these displays: This creates an extended desktop across both monitors. This is great for multitasking or for complex desktop setups, but may take some getting used to before it becomes intuitive.
- «Show desktop only on 1» or «Show desktop only on 2»: If you’re using a second monitor to improve your ergonomic situation, this is likely the way to go. Power off one monitor (usually the laptop’s primary screen) and focus on the other at a neck-friendly angle.
When you’re done, click the OK button to close the Display Settings dialog box. That’s how it works.
If you cannot see the additional monitor(s) listed, click Detect. If it does not work, try restarting your computer and repeat steps.
These days everybody has more than one monitor available. However, running a dual monitor setup can be tricky to get working correctly. This tech-recipes tutorial will get you started.
These directions are for Windows 7 although the directions for XP and Vista are very similar.
Dual monitors rule! First things first, make sure your computer can support two monitors. The box will need the right outputs for dual monitors. I use a higher end GPU which allows me multiple HDMI outputs; however, Windows 7 is smart enough to use outputs of different types. For example, if you computer has a DVI and VGA outputs, you still can get a dual setup working. Most laptops have an external monitor connection which can be used as your second monitor.
1. Open the Start button on your desktop and in the search bar type Display. Click on the Display option when it appears.
2. From this control panel screen select Adjust Resolution on the left.
3. Your second monitor should be detected. If it is not click Detect then Identify. My favorite thing to do is use both monitors as one big desktop. To do this, under Multiply Display select Extend these displays. You will likely want to make sure your left monitor is set as the main display where your Windows task bar will appear.
4. You can also duplicate the display which clone the image one one monitor to the second one.
Hopefully, you are now running a two monitor setup. If you find yourself having trouble getting your second monitor to display, just post in the comments and I will help you out. Check out Jimmy’s dual monitor tricks for additional cool things to do with a two monitor configuration.

You can check the information of your graphics card by going to the hardware manufacturer’s website, and searching for your graphics card. An example:
2) Compare the physical connections
Compare the available video ports on your computer with those on your monitor to find which one(s) they have in common.
- On a desktop computer: The video ports are located on the back of the computer.
- On a laptop computer: The video ports may be on the back, left or right-hand side of the computer.
- On a monitor: The video ports may be on the back of the monitor or on a overhang parallel to the stand.
In order to connect your monitor to your computer properly, it’s important to ensure that the video port on your computer matches an available video port on your monitor, like VGA, DVI, HDMI or DisplayPort (DP).
- Video Graphics Array (VGA) is normally color-coded with blue plastic and labels.
- Digital Video Interface (DVI) is usually color-coded with white plastic and labels.
- High-Definition Multimedia Interface (HDMI) can connect all kinds of video devices and provide sounds through the cable.
- Display Port (DP) can provide an interface with an optional audio high-definition content protection.
3) Connect the video and power cables
- Plug in the power cord to your monitor and the power outlet.
- Make sure your computer is turned on.
- Connect your monitor to your computer using a compatible cable. This cable should already be provided by the monitor manufacturer.
- Once the cables are connected securely, your Windows 7 computer should automatically detect and display the desktop screen on the connected monitors. By default, Windows 7 will duplicate the displays on all monitors.
Step 2: Set up dual monitors
- Right-click on any empty area of your Windows desktop, and select Screen resoltution.
