如今，设置双显示器(Dual Monitors)很常见。无论您是想增加工作屏幕区域还是只想将某些内容镜像到另一台显示器，Windows都能满足您的需求。随着Windows 11和Windows 10中改进的功能，现在您可以使用一些熟悉的命令轻松设置双显示器。我们已经了解了如何在 Windows 7和Windows 8.1上设置双显示器。现在让我们看看如何set up the dual monitors on Windows 11/10。我们还将讨论如果您的Windows 10 无法检测到第二台显示器(Windows 10 cannot detect the second monitor)，您可以采取哪些措施。
(Set)在 Windows 11/10 上设置双显示器(Dual)
双显示器(Dual Monitor)设置的硬件要求
显然，您需要一个额外的显示器，此外，您可能还需要一些电线和连接器。第一步也是最重要的一步是检查计算机上的端口。如果您使用的是笔记本电脑，您可能只有一个HDMI端口，或者很少有VGA端口。如果您在计算机上并且已经连接了一台显示器，请寻找另一个类似的端口。在购买任何设备之前，请(Make)确保您的计算机或显卡支持多台显示器。通常，VGA端口在三行中有几个小孔。
现在是时候买一根合适的电线了。如果两个设备（显示器和 PC(Monitor and the PC)）都与HDMI兼容，您可以获得HDMI线。通常，旧显示器仅与VGA兼容，因此您需要一根VGA线和一个HDMI 到 VGA 转换器(HDMI to VGA converter)。连接显示器并打开电源！
设置第二台显示器
好吧， Windows(Windows)中有四种投影模式可用。您只需按键盘上的“ Win + P ”即可打开投影菜单。第一种模式是“仅 PC 屏幕(PC Screen Only)”，在此模式下，辅助显示器不会显示任何内容。还有一种模式可以只打开副屏，关闭主屏。接下来(Next)是两种最常用的投影模式。“复制”(Duplicate’ )模式可让您将屏幕投影到第二台显示器上。
最后也是最重要的模式“扩展”(Extend’)让您可以将实际工作区域扩展到第二台显示器。双显示器设置本质上是关于在您的计算机上以这种模式工作。您可能见过有人合作使用几台显示器来制作更大的屏幕。该设置只不过是在这种“扩展”模式下工作。
在Windows(Windows)中配置第二个监视器
而“复制”模式不需要任何配置。但是我们需要配置以“扩展”模式连接的显示器以充分利用它。在您的主显示器上，右键单击桌面并选择“显示设置”。大部分设置都可以在此页面上进行配置，首先，您需要定义第二台显示器相对于第一台显示器的位置。例如，我将显示器放在笔记本电脑的左侧，因此我将第二个框拖到第一个框的左侧。此外，如果两个显示器不在同一水平面上，您可以进行一些高度调整。
两个显示器的设置可以单独配置。您可以更改显示器分辨率、缩放布局等等。此外，您可以更改主监视器。
更改Windows 11(Windows 11)中的主显示器
要更改Windows 11中的主显示器，请选择与所需显示器关联的编号，单击“ 多个显示器 (Multiple displays )”部分以展开它，然后勾选 “将此作为我的主显示器” (Make this my main display )复选框。
在Windows 11(Windows 11)中的第二个或所有显示器上显示或隐藏任务栏(Taskbar)
您可以更改一些与任务栏相关的设置。要在第二个或所有显示器上显示或隐藏任务栏(Taskbar)，您需要按 Win+I 打开Windows 设置(Windows Settings)并转到 Personalization > Taskbar。在这里，单击 任务栏行为(Taskbar behaviors) 部分将其展开。
(Set)在Windows 11(Windows 11)中的一个或多个显示器上设置壁纸
壁纸相关设置也可以自定义。您可以拉伸墙纸以适应两个显示器。或者，您可以将相同的壁纸镜像到两个屏幕。更进一步，您可以在两个屏幕上拥有完全不同的壁纸。如果您使用的是Windows 11，则需要转到 Personalization > Background。然后，右键单击墙纸，然后选择 为所有桌面(Set for all desktops) 设置选项以在多个显示器上设置一个墙纸。
更改Windows 10(Windows 10)中的主显示器
要更改Windows 10中的主显示器，请选择与该显示器对应的数字，向下滚动并选择“将此作为我的主显示器”(Make this my main display’)。主监视器通常是显示大部分细节并托管主桌面的监视器。虽然任务栏在两台显示器上都可用，但主要的功能更实用且更易于访问。
在Windows 10(Windows 10)中的第二个或所有显示器上显示或隐藏任务栏(Taskbar)
在Windows 10中，右键单击任务栏并选择“任务栏设置”(Taskbar Settings’)。向下滚动以找到“多个显示器(Multiple displays)”。在这里，您可以更改一些与任务栏相关的设置，例如是否在辅助显示器上显示任务栏或在何处显示任务栏按钮以及何时组合按钮和标签。
如果您想在所有显示器上显示任务栏(Taskbar)，您必须勾选 在所有显示器上显示我的任务栏 (Show my taskbar on all displays )复选框。
您还可以展开“ 使用多个显示器时，(When using multiple displays, show my taskbar apps on)在下拉列表中显示我的任务栏应用程序”，然后从以下选项中选择一个选项：
- 所有任务栏
- 主(Main)任务栏和打开窗口的任务栏
- 打开窗口的任务栏
(Set)在Windows 10(Windows 10)中的一台或多台显示器上设置壁纸
在Windows 10中，右键单击桌面并选择“个性化”。(Personalize’.) 浏览(Browse)要应用的壁纸。右键单击(Right-click)其缩略图以选择要应用此壁纸的显示器。
但是，如果您想在不同的显示器上设置不同的壁纸，您需要选择 设置为桌面 (Set for desktop )> 桌面 1 (Desktop 1 )或 桌面 2 (Desktop 2 )或任何其他编号。如果您想在两台显示器上使用单一壁纸，请确保您手头有一张高质量的宽壁纸。宽壁纸专为多显示器而设计，它们可以在没有任何异常拉伸和质量失真的情况下应用。而且，它们看起来很漂亮。
注意(NOTE)：当您连接多台显示器时，任务栏(Taskbar) 属性(Properties)中会提供一个新选项。要配置此选项，请右键单击任务栏(Taskbar)并选择属性(Properties)。在底部的多个显示器(Multiple displays)下，您可以选择在主显示器或所有显示器上显示任务栏。(Taskbar)您还可以从下拉菜单中配置任务栏按钮的显示位置。

(Does)Windows 11是否支持双显示器？
是的，Windows 11支持像(Windows 11)Windows 10这样的双显示器。您可以使用几乎相同的一组选项来使用Windows 11配置双显示器。例如，您可以选择是否要扩展显示器、复制它们等。除此之外，您还可以设置不同的壁纸、显示或隐藏任务栏(Taskbar)等。
如何在Windows 11中更改我的主显示器？
要在Windows 11(Windows 11)中更改主显示器，您需要按Win+I打开Windows 设置(Windows Settings)并转到 System > Display。然后，选择要设置为主显示器的所需显示器。之后，展开 多显示器 (Multiple displays )部分，然后勾选将其 设为我的主显示器(Make this my main display) 复选框。
Hope this helps you in setting up dual monitors on Windows 11/10. As I already mentioned there is improved support for dual monitors in Windows 11/10. You can use this setup anywhere at your convenience.
How to set up Dual Monitors on Windows 11/10
Setting up Dual Monitors is a common thing these days. Whether you want to increase your working screen area or just want to mirror something to another monitor, Windows has got it all. With improved functionality in Windows 11 and Windows 10, now you can set up dual monitors easily and with some familiar commands. We’ve already seen how to set up dual monitors on Windows 7 and on Windows 8.1 too. Now let’s check out how to set up the dual monitors on Windows 11/10. We will also discuss what you can do if your Windows 10 cannot detect the second monitor.
Set up Dual Monitors on Windows 11/10
Hardware requirements for Dual Monitor setup
Obviously, you’ll need an extra monitor and along with that, you may require some wires and connectors. The first and foremost step is checking the ports on your computer. If you are using a laptop, you might have only one HDMI port or rarely a VGA port along with it. If you are on a computer and one monitor is already connected, look for another similar port. Make sure your computer or the graphics card supports multiple monitors before buying any equipment. Typically, a VGA port has several small holes in three lines.
Now it is time to get a suitable wire. If both the devices (Monitor and the PC) are compatible with HDMI, you can get an HDMI wire. Usually, the old monitors are compatible only with VGA, so you’ll need a VGA wire and an HDMI to VGA converter. Connect the monitor and power it on!
Setting up the second monitor
Well, there are four projection modes available in Windows. You can open up the projection menu by simply pressing ‘Win + P’ from the keyboard. The first mode is ‘PC Screen Only’ and in this mode, the secondary monitor will not display anything. There is also a mode that can turn on the secondary screen only and turn off the primary screen. Next, comes the two mostly used projection modes. The ‘Duplicate’ mode lets you project the screen as it is on the second monitor.
The last and the most important mode, ‘Extend’ lets you extend your actual working area to the second monitor. The dual monitor setup is essentially about working in this mode on your computer. You might have seen someone who has collaborated a few monitors to make a larger screen. That setup is nothing but working in this ‘Extend’ mode.
Configure the second monitor in Windows
While the ‘Duplicate’ mode does not require any configuration as such. But we need to configure the monitor connected in ‘Extend’ mode to get the best out of it. On your primary monitor, right-click on the desktop and select ‘Display Settings’. The majority of settings can be configured on this page, first of all, you need to define the position of the second monitor with respect to the first monitor. For example, I’ve placed the monitor to the left of my laptop so I will drag the second box to the left of the first one. Also, you can make some height adjustments if both the monitors are not on the same level.
The settings for both the monitors can configure separately. You can change monitor resolutions, scale layout and much more. Also, you can change the primary monitor.
Change the primary monitor in Windows 11
To change the primary monitor in Windows 11, select the number associated with the desired monitor, click on the Multiple displays section to expand it, and tick the Make this my main display checkbox.
Show or hide the Taskbar on the second or all displays in Windows 11
You can change a few taskbar-related settings. To show or hide the Taskbar on the second or all displays, you need to press Win+I to open the Windows Settings and go to Personalization > Taskbar. Here, click the Taskbar behaviors section to expand it.
Set wallpaper on one or multiple displays in Windows 11
Wallpaper-related settings can also be customized. You can stretch a wallpaper to fit both the displays. Or you can have the same wallpaper mirrored to both screens. Even further you can have entirely different wallpapers on both the screens. If you are using Windows 11, you need to go to Personalization > Background. Then, right-click on the wallpaper, and select the Set for all desktops option to set one wallpaper on multiple displays.
Change the primary monitor in Windows 10
To change the primary monitor in Windows 10, select the number corresponding to that monitor, scroll down and select ‘Make this my main display’. The primary monitor is generally the one that displays the majority of details and hosts the primary desktop. Although the taskbar is available on both the monitors but the primary one is more functional and accessible.
Show or hide the Taskbar on the second or all displays in Windows 10
In Windows 10, right-click the taskbar and select ‘Taskbar Settings’. Scroll down to find ‘Multiple displays’. Here you can change a few taskbar-related settings like whether to show taskbar on a secondary display or where to show taskbar buttons and when to combine buttons and labels.
If you want to show the Taskbar on all displays, you must tick the Show my taskbar on all displays checkbox.
You can also expand the When using multiple displays, show my taskbar apps on the drop-down list and choose an option among these:
- All taskbars
- Main taskbar and taskbar where the window is open
- Taskbar where the window is open
Set wallpaper on one or multiple displays in Windows 10
In Windows 10, right-click the desktop and select ‘Personalize’. Browse for a wallpaper that you want to apply. Right-click its thumbnail to select the monitor you want to apply this wallpaper on.
However, if you want to set different wallpaper on a different monitor, you need to select the Set for desktop > Desktop 1 or Desktop 2 or any other number. If you want a single wallpaper on both the monitors, make sure you have a high-quality wide wallpaper in hand. Wide wallpapers are specially designed for multiple displays and they can be applied without any unusual stretching and quality distortion. Also, they look quite beautiful.
NOTE: When you connect multiple monitors, a new option is offered in Taskbar Properties. To configure this option, right-click on the Taskbar and select Properties. Towards the bottom, under Multiple displays, you can opt to show the Taskbar on your primary monitor or all the monitors. You can also configure where to show the taskbar buttons from the drop-down menu.
