当您想在使用多个窗口或应用程序的同时提高多任务处理效率时，具有多个显示器的系统会派上用场。它也感觉不那么拥挤。您需要正确配置它以使其更实用。
无论您是游戏玩家、内容创建者还是数据分析师，本指南都将向您展示如何在Windows操作系统中设置双显示器。
在 Windows 10 上设置双显示器(Setup Dual Monitors On Windows 10)
Windows 10 具有多种功能和设置，可支持多台显示器，而无需使用第三方应用程序，并使用Windows 7中熟悉的命令。
无论您是想为台式机或工作站(desktop or workstation)设置双显示器，还是为笔记本电脑设置外接显示器，请使用以下步骤进行设置。
使用电缆连接(Connect Using Cables)
在配置双显示器设置(monitor setup)之前，请确保您拥有连接 PC 和显示器所需的所有电缆。(cables you need)
查看您计算机上的端口类型，根据您的 PC 位于侧面或背面。其中包括使用HDMI、VGA、DVI或DisplayPort的视频信号，以及连接电源线。
对你的显示器做同样的事情，如果你不确定，如果你想知道如何连接显示器，请检查它的品牌和型号。(make and model)您可以在显示器背面或底部(back or underside)找到端口。
注意(Note)：您 PC 上的视频连接(video connection)必须与您的显示器匹配。如果您的 PC 只有DVI 连接(DVI connection)而您的显示器没有(monitor doesn)，您可以使用转换电缆(converter cable)或特殊适配器。
最流行和广泛使用的受支持的显示连接(display connection)类型是HDMI。您会在几乎所有电视和大多数计算机显示器上找到它，它们至少有一个此类端口，因此找到(TVs)HDMI 电缆(HDMI cable)应该不难。
同样，HDMI 端口(HDMI port)也有不同的类型，包括用于小型设备的mini 和 micro HDMI(mini and micro HDMI)，或标准HDMI 端口(HDMI port)。
但是，较旧的计算机可能具有VGA 或 DVI 端口(VGA or DVI ports)，它们依靠电缆上的金属针连接到您的 PC。较新(Newer)的显示器不支持这些类型的连接，但您可以尝试从DVI转换为HDMI。
DisplayPort(DisplayPort isn)不像HDMI那样常见，但高端笔记本电脑、相对较新的计算机显示器和专用显卡可能具有这种连接。在较新的Android(Android)智能手机和最近的MacBook(MacBooks)上也有USB-C连接，您可以将这种类型与支持USB-C 输入(USB-C input)的显示器一起使用。或者，您可以获得带有USB-C到HDMI/DisplayPort连接的电缆。
插入与您的PC 和显示器(PC and monitor)匹配的电缆，将电源线连接(power cable)到电源插座(power outlet)，然后打开显示器。
配置显示(Configure The Display)
下一步是配置您的演示文稿显示(presentation display)。
为此，您将使用第二台显示器复制或扩展桌面显示(desktop display)，以便Windows可以识别和使用该显示器。在大多数情况下，Windows无需您的输入即可自动检测和配置显示器，但请按照以下步骤执行配置。
- 转到您的 PC 桌面并右键单击任何空白区域。
- 选择显示设置(Display Settings)。
- 向下滚动到Multiple Displays并单击Detect。
- 对于无线显示器，单击多显示器下的连接到无线显示器(Connect to a wireless display)。
无线显示器(wireless monitor)允许您的PC 或具有Miracast 功能的移动设备通过(Miracast capability)WiFi Direct 接口(WiFi Direct interface)将我们的屏幕图像显示到您的显示器。您可以将您的桌面无线复制或扩展至显示器，并通过WiFi通过(WiFi)Dual Cast连接您的移动设备（取决于您的设备）。
您还可以通过单击识别来选择(Identify)监控顺序(monitor order)。Windows 将在每个屏幕上显示数字 1(number 1)和 2，因此这有助于您了解哪个是哪个。
- 如果您希望您的 PC 成为您的主屏幕，请返回“多显示器”部分(Multiple Displays section)并选中“将此作为我的主显示器(Make this my main display )”框，或将此设备用作主显示器(Use this device as the primary monitor)。
注意(Note)：primary/main screen将包含您的开始菜单(Start menu)、时钟、任务栏和其他应用程序，但您可以通过右键单击Windows taskbar > Properties > Show taskbar on all displays将它们显示在两个屏幕上。
- 相应地调整屏幕方向和分辨率，并通过选择(screen orientation and resolution)Keep Changes保存新的显示设置。
个性化您的显示器显示顺序(Personalize Your Monitor Display Order)
连接第二台显示器并连接显示器后，您可以对其进行增强和个性化。您可以在这里做不同的事情，包括：
- 仅在您的 PC 上而不是第二台显示器上显示开始屏幕。(Start screen)
- 设置任务栏首选项（右键单击Taskbar > Settings > Taskbar preferences）。
- 个性化您的背景图像(background image)（右键单击Desktop > Personalize并选择图像、主题或颜色）。
注意(Note)：Windows 10 有一个新的全景主题，可让您跨显示器跨越全景图片。为此，请单击Start > Settings > Personalization.
单击浏览(Click Browse)以选择全景图像。单击Choose a fit > Span”，一切就绪。
如何在 Windows 8 和 7 中使用双显示器(How To Use Dual Monitors In Windows 8 & 7)
如果您使用的是Windows 8或 7，则可以设置双显示器。这些步骤可能与(Windows 8)Windows 10中的步骤略有不同，但最终您仍然可以设置双显示器。
- 确保(Make)PC 和显示器(PC and monitor)已连接，然后按键盘上的WindowsWindows Key+P
- 从四个选项中进行选择：仅计算机、复制、扩展、仅投影仪(Computer only, Duplicate, Extend, Projector only)。
- 右键单击您的桌面并选择(desktop and select) 屏幕分辨率(Screen Resolution)。
- 单击多个显示器(Multiple displays)，然后单击复制(Duplicate)或扩展(Extend)以在两个屏幕上显示相同的图像，或在两个设备上扩展您的桌面。如果您看不到显示器，请单击检测(Detect)。
- 如果显示器的品牌和型号(make and model)不同，请通过右键单击桌面并选择(desktop and selecting) Display Settings使显示器匹配。转到选择并重新排列显示器(Select and rearrange displays)并尝试匹配桌面上显示器的方向。您可以通过单击并拖动矩形来匹配，直到它们正确排列。
使用扩展坞设置双显示器(Setup Dual Monitors Using a Docking Station)
坞站(docking station)提供了一种将鼠标、键盘、外部硬盘驱动器、打印机和外部显示器等多个外围设备连接到 PC 的简单方法。它更像是一个端口复制器(port replicator)，因为它提供了更多端口，而您的PC(PC doesn)由于其有限的连接端口而无法提供这些端口。
大多数坞站可以连接多台显示器，因为它们有更多的视频端口，一旦你将它连接到你的电脑，你就可以关闭它的屏幕并改用你的显示器。
使用投射设备设置双显示器(Setup Dual Monitors Using a Casting Device)
您还可以将 PC 的屏幕复制到第二台显示器或(monitor or display)使用诸如 Google Chromecast 之类的投射设备(casting device like Google Chromecast)进行显示。
您可以使用Google Chromecast(Google Chromecast)做很多很酷的事情，包括从视频播放器(video player)、音乐文件或播客、整个桌面甚至浏览器选项卡投射到双显示器。
- 要投射整个桌面，请单击浏览器右上角的Chromecast 图标。(Chromecast icon)我们在本指南中使用了Google Chrome，因此请转到“设置”菜单(Settings menu)（三个点）并单击“投射(Cast)” 。
- 单击投射桌面(Cast Desktop)，然后单击所需的屏幕。由于它们是两个屏幕，因此您必须选择要投射的屏幕，以及是否也要投射音频。
- 选择您的首选选项，然后单击共享(Share)。屏幕将通过Chromecast投射到您的显示器上，显示任务栏等元素。但是，这并不意味着您可以在两个屏幕之间移动打开的程序或窗口或应用程序。
双倍的屏幕空间(Double Your Screen Space)
在Windows(Windows)中设置双显示器是一个简单的过程，但除了PC 上的默认方法之外，您还可以使用不同的方法进行设置。(default method)您(Were)是否能够使用上面列出的步骤和方法设置双显示器？通过在下面发表评论让我们知道。
How to Setup Dual Monitors in Windows
A system with multiple monitors comes handy when you want to improve your multitasking productivity while working with multiple windows or applications. It also feels less cramped. You need to configure it correctly to make it more practical though.
Whether you’re a gamer, content creator, or data analyst, this guide will show you how to setup dual monitors in Windows operating system.
Setup Dual Monitors On Windows 10
- Connect using cables
- Use a docking station
- Using a casting device
Windows 10 has various features and settings that support multiple monitors without having to use third-party apps, and using familiar commands as those in Windows 7.
Whether you want to setup dual monitors to your desktop or workstation, or an external display to your laptop, use the steps below to set it up.
Connect Using Cables
Before you configure the dual monitor setup, make sure you have all the cables you need to connect your PC and monitor.
Look at the types of ports you have on your computer, either on the sides or at the back depending on your PC. These include the video signal using HDMI, VGA, DVI, or DisplayPort, and the connecting power cables.
Do the same for your monitor, and if you’re not sure, check its make and model if you’re to know how to connect the display. You can find the ports at the back or underside of the monitor.
Note: The video connection on your PC must match that of your monitor. If your PC only has the DVI connection and your monitor doesn’t have one, you can use a converter cable or special adapter.
The most popular and widely used supported type of display connection is HDMI. You’ll find it on almost all TVs and most computer monitors, which have at least one of this type of port, so it shouldn’t be difficult to find an HDMI cable.
Similarly, HDMI ports come in different types including the mini and micro HDMI for smaller devices, or the standard HDMI port.
However, older computers may have VGA or DVI ports, which rely on metal pins on their cable to connect to your PC. Newer monitors lack support for these types of connections, but you could try to convert from DVI to HDMI though.
DisplayPort isn’t as common as HDMI, but higher end laptops, relatively recent computer monitors and dedicated graphics cards may have this kind of connection. There’s also the USB-C connection on newer Android smartphones and recent MacBooks, and you can use this type with a monitor that supports USB-C input. Alternatively, you can get a cable with USB-C to HDMI/DisplayPort connections.
Plug the cable that matches both your PC and monitor, connect the power cable to a power outlet, and turn on the monitor.
Configure The Display
The next step is to configure your presentation display.
To do this, you’re going to duplicate or extend the desktop display with your second monitor so that Windows can recognize and use the monitor. In most cases, Windows automatically detects and configures the monitor without your input, but take the steps below to perform the configuration.
- Go to your PC’s desktop and right-click on any empty space.
- Select Display Settings.
- Scroll down to Multiple Displays and click Detect.
- For a wireless monitor, click Connect to a wireless display under Multiple Displays.
A wireless monitor allows your PC or mobile device with Miracast capability to display our screen’s image to your monitor via a WiFi Direct interface. You can duplicate or extend your desktop wirelessly to the monitor and connect your mobile device through Dual Cast via WiFi (depending on your devices).
You can also choose the monitor order by clicking Identify. Windows will display number 1 and 2 on each screen, so this helps you know which one is which.
- If you want your PC to be your primary screen, go back to the Multiple Displays section and check the Make this my main display box, or Use this device as the primary monitor.
Note: The primary/main screen will have your Start menu, clock, taskbar and other applications, but you can have them on both screens by right-clicking your Windows taskbar > Properties > Show taskbar on all displays.
- Adjust the screen orientation and resolution accordingly, and save the new display settings by selecting Keep Changes.
Personalize Your Monitor Display Order
Once the second monitor is connected and the display is attached, you can enhance and personalize it. There are different things you can do here including:
- Showing the Start screen only on your PC and not the second monitor.
- Setting taskbar preferences (right-click Taskbar > Settings > Taskbar preferences).
- Personalizing your background image (right-click Desktop > Personalize and select images, themes or colors).
Note: Windows 10 has a new panoramic theme that allows you to span a panoramic picture across monitors. To do this, click Start > Settings > Personalization.
Click Browse to choose a panoramic image. Click Choose a fit > Span, and you’re all set.
How To Use Dual Monitors In Windows 8 & 7
You can setup dual monitors if you’re using Windows 8 or 7. The steps may vary slightly from those in Windows 10, but ultimately you’ll still be able to setup dual monitors.
- Make sure the PC and monitor are connected, and then press Windows Key+P on your keyboard.
- Choose from the four options: Computer only, Duplicate, Extend, Projector only.
- Right-click on your desktop and select Screen Resolution.
- Click Multiple displays and then click either Duplicate or Extend to show the same image on both screens, or extend your desktop across the two devices. If you can’t see your monitor, click Detect.
- Make the displays match if they’re not of the same make and model by right-clicking your desktop and selecting Display Settings. Go to Select and rearrange displays and try to match the orientation of the monitors on your desktop. You can do this by clicking and dragging the rectangles around to match until they line up properly.
Setup Dual Monitors Using a Docking Station
A docking station offers a simple way of connecting multiple peripherals like your mouse, keyboard, external hard drives, printer and external monitors to your PC. It’s more of a port replicator as it provides more ports, which your PC doesn’t readily offer owing to its limited connectivity ports.
Most docking stations can connect multiple monitors as they have more video ports, and once you connect it to your PC, you can switch its screen off and use your monitor instead.
Setup Dual Monitors Using a Casting Device
You can also duplicate your PC’s screen to a second monitor or display using a casting device like Google Chromecast.
There are many cool things you can do with Google Chromecast including casting to dual monitors from a video player, music files or podcasts, your entire desktop or even browser tabs.
- To cast your entire desktop, click on the Chromecast icon at the top right of your browser. We used Google Chrome for this guide, so go to the Settings menu (three dots) and click Cast.
- Click Sources just below the displays.
- Click Cast Desktop and then click the screen you want. Since they’re two screens, you’ll have to choose the one you want to cast, and whether or not you’d like to cast audio as well.
- Select your preferred options and then click Share. The screen will cast to your monitor via Chromecast, showing elements including the taskbar and more. However, this doesn’t mean you can move open programs or windows, or apps between the two screens.
Double Your Screen Space
Setting up dual monitors is a straightforward process in Windows, but there are different ways you can do it besides the default method on your PC. Were you able to set up dual monitors using the steps and methods listed above? Let us know by leaving a comment below.
