(Mac)从事严肃工作或只是喜欢在工作时关注电子邮件或社交媒体的
Mac用户需要第二个显示器甚至多个显示器。
在 macOS 中设置多个显示器很容易，但有些细节可能会让您感到困惑。以下是您需要了解的内容以及如何启动并运行您的Mac“战斗站”。
macOS 中
多显示器(Multiple Displays)的要求
在使用Mac(Mac)设置多个显示器之前，您必须准备好一些东西。这是清单：
- 您将需要至少两个显示器才能设置多显示器配置。您的Mac应至少有一个HDMI、DisplayPort、mini DisplayPort、Thunderbolt 或 DVI(HDMI, DisplayPort, mini DisplayPort, Thunderbolt, or DVI)端口来连接附加显示器。
- 根据Mac和显示器上可用的连接器，您可能需要适配器或电缆将显示器连接到Mac。例如，如果您的Mac具有Thunderbolt端口并且您的显示器具有HDMI端口，则您将需要Thunderbolt转HDMI电缆或适配器。
- 您需要至少运行 macOS Mavericks (10.9) 才能在(Mavericks)Mac上使用多个显示器。将 macOS 更新(Updating macOS)到计算机支持的最新版本是个好主意。
- 您的办公桌上需要足够的空间来容纳所有显示器。确保您有足够的空间来并排放置显示器或采用适合您的配置。
大多数显示器都具有VESA安装座，因此您可以在显示器安装座上发挥创意。显示器支架价格实惠，可通过旋转、倾斜和旋转升级主流显示器。更不用说，它们是保持办公桌整洁、工作空间宽敞的好方法。
我的 Mac 只有 Thunderbolt 端口！
如果您的 Mac 仅具有Thunderbolt 3或Thunderbolt 4端口，并且您想要连接额外的显示器，则需要使用Thunderbolt（或USB-C）转HDMI或DisplayPort适配器或线缆。在这种情况下，大多数人都会选择使用Thunderbolt或USB-C坞站端口，它们带有显示连接和其他外围设备的多个连接。
如果您的Mac是较旧的Intel型号，没有Thunderbolt 3端口，则可能有HDMI、DisplayPort、DVI或VGA端口。您可以使用与Mac(Mac)和显示器端口
兼容的电缆或适配器来连接附加显示器。
例如，如果您的Mac有DVI端口，而您的显示器有HDMI端口，您可以使用DVI转HDMI适配器或电缆将显示器连接到Mac。
如何将其他(Connect Additional) 显示器(Monitors)连接到您的Mac
现在我们确信您已具备进行多显示器Mac设置所需的一切，下面介绍了如何将其他显示器连接到您的Mac：
- 检查Mac(Mac)背面或MacBook侧面，了解哪些端口可用。您的Mac可能有HDMI、DisplayPort、Thunderbolt、DVI或VGA端口。
- 检查显示器背面，了解哪些端口可用。您的显示器可能有HDMI、DisplayPort、DVI或VGA端口。
- 根据Mac(Mac)和显示器上的可用端口，选择适当的电缆或适配器将显示器连接到Mac。例如，如果您的Mac具有Thunderbolt端口并且您的显示器具有HDMI端口，则您将需要Thunderbolt转HDMI适配器或电缆。
- 使用您选择的电缆或适配器，将显示器连接到您的Mac。确保将电缆连接到(Make)Mac和显示器
上的相应端口。
将显示器连接到Mac后，打开显示器。在大多数情况下，您的Mac会自动检测屏幕并尝试以最佳方式配置它们。如果发生这种情况，你就可以走了！
如果您的显示器没有立即开始工作，我们可以尝试强制 macOS 检测它：
- 在屏幕顶部的系统菜单栏中(Menu Bar)，转到Apple按钮> System Settings > Displays。这可能是旧版本 macOS 上的“系统(System) 偏好设置”。(Preferences)
- 按住Option按钮，“Detect Displays”应该出现在“Night Shift”的位置。不幸的是，由于选项(Option)切换的工作原理，我们无法对其进行屏幕截图，但它出现在这个位置。
- 使用“检测显示器”(Detect Displays)按钮，然后查看您的显示器是否被识别。它应该出现在窗口顶部的显示图中。
如果仍未检测到您的显示器，请尝试在连接所有设备的情况下重新启动Mac，或者尝试在重新启动后连接所有设备。
在 macOS 中
调整多显示器的显示设置(Display Settings)
一旦检测到您的显示器并处于活动状态，macOS 将尝试以合理的顺序排列它们，但您可能希望将它们排列为与它们的物理配置完全匹配：
- 转至Apple按钮> System Settings > Displays。
- 选择排列。
- 使用鼠标指针将代表显示器的图片拖动到正确的排列位置。
最后一步是调整每台显示器以获得正确的分辨率、颜色配置文件和刷新率。请注意， MacBook Air(MacBook Air)或MacBook Pro上内置显示器的设置看起来与外接显示器的设置不同。您无法调整内置显示器的分辨率或刷新率，但可以调整桌面缩放比例，以充分利用高分辨率屏幕。
要在 macOS 中调整外部显示器的显示设置，请按照以下步骤操作：
- 转至Apple Button > System Settings > Displays。
- 选择您要修改的显示。
现在选择了显示器，我们可以更改该显示器的不同显示选项。
在“用途(Use)”下，您可以设置给定显示器是主显示器还是扩展显示器。当您将外接显示器连接到MacBook并且希望外接显示器在连接时成为主屏幕时，此功能非常有用。
在此部分中，您还可以镜像显示。请记住，如果两台显示器具有不同的分辨率或宽高比，您可能最终会在其中一台屏幕上出现难看的缩放或黑条。
在“用途”下方(Below Use)，您将看到分辨率列表。通常最好选择与屏幕的原始分辨率相匹配的分辨率。
如果您使用“显示(Show)所有分辨率”开关，您将看到更多选项，但有些选项可能不适用于您的显示器，从而导致黑屏，直到确认期结束。
颜色配置文件部分可让您为显示器选择颜色配置文件。(Color)通常，这默认为特定屏幕型号的颜色调整。但是，您也可以根据您想要做的工作选择另一个标准。例如，许多从事图像编辑的专业人士会选择Adobe色彩空间以获得一致的色彩结果。
刷新率可让您调整显示器每秒刷新图像的次数。一般来说，假设您的显示器已正确报告其接受的刷新率，最好选择最高的可用数字。
高动态范围(Dynamic Range)可让您在支持 HDR 的显示器上激活HDR 。如果您想要播放或编辑HDR内容，则应针对该显示器打开此功能。然而，SDR内容在(SDR)HDR开启时往往看起来不太舒服，因此只有在实际使用HDR内容时才开启此功能。
最后，您可以调整屏幕的旋转。如果您有一个可以旋转的屏幕，那么当您想将其翻转或在纵向模式下使用时，这会很有用。
根据您的喜好调整每个屏幕的设置后，您可以关闭窗口。每次连接这些显示器时，设置将保持不变，直到您进行更改。
您可以(Can)连接多少个外部(External)显示器？
虽然大多数人很高兴拥有双显示器设置，但许多人正在接受“战斗站”方法并设置大量显示器以使他们的工作流程更轻松。在您出去购买一堆显示器之前，您应该知道可以连接到 Mac 的外部显示器的数量是有限的(Mac)。
- 如果您想知道您的Mac(Mac)支持多少台显示器，请前往Apple 菜单(Apple Menu)> 关于本机(Mac)，然后将您的序列号复制到剪贴板。
- 前往 Apple 的技术规格(Tech Specs)网站，选择搜索技术规格(Search Tech Specs)栏，然后将 Mac 的序列号粘贴到提供的空间中。然后选择搜索(Search)。
- 在结果中选择您的Mac型号。
- 在Mac(Mac)的规格下，您可以找到该型号支持的最大显示器数量。
一些较旧的Mac(Macs)甚至可能不支持双显示器，因此在花钱之前检查一下很重要！
使用 iPad 作为外部(External)显示器
虽然（Mac Mini除外）M1 和M2 Mac(M2 Macs)官方仅支持一台外接显示器，但有一种方法可以获得第三台显示器。最新版本的 macOS 和 iPadOS 支持SideCar，使您的 iPad 可以用作扩展显示器，并且不计入显示限制。
有几个要求：
- 兼容的 Mac 和 iPad(compatible Mac and iPad)。
- 至少 macOS Catalina和 iPadOS 13。
- 用于连接Mac(Mac)和 iPad的（可选）电缆。
- 两台设备都必须打开
蓝牙。(Bluetooth)
- 两台设备必须登录同一个Apple ID。
只要满足要求，当您选择 + 下拉菜单时，您应该会在“显示”下看到您的 iPad 选项。
只需选择“扩展”或“镜像到 iPad”，几秒钟后，iPad 就会显示您的 macOS 桌面。总的来说，您现在可以像对待任何其他外部显示器一样对待 iPad。
需要更多显示器吗？尝试显示链接(Try DisplayLink)！
DisplayLink是一项允许您使用USB或Thunderbolt连接将其他显示器连接到Mac 的(Mac)技术。如果您想要在基于 M1 芯片的Mac上使用(Mac)DisplayLink来超出显示器限制，则需要使用DisplayLink供电的坞站或适配器。
要在基于 M1 芯片的Mac(Mac)上使用附加显示器，您需要在Mac上安装DisplayLink软件。您可以从DisplayLink(DisplayLink)网站下载该软件。
How to Set Up Multiple Monitors in macOS
Mac users who do serious work or juѕt like to keep an eye on emails, or social media, while on the job need a second display or even multiple monitors.
It’s easy to set up multiple monitors in macOS, but some details can trip you up. Here’s what you need to know and how to get your Mac “battle station” up and running.
Requirements For Multiple Displays in macOS
Before you can set up multiple monitors with your Mac, you must have a few things ready. Here’s the checklist:
- You will need at least two monitors to set up a multiple monitor configuration. Your Mac should have at least one HDMI, DisplayPort, mini DisplayPort, Thunderbolt, or DVI port to connect an additional monitor.
- Depending on the connectors available on your Mac and your monitors, you may need adapters or cables to connect the monitors to your Mac. For example, if your Mac has a Thunderbolt port and your monitor has an HDMI port, you will need a Thunderbolt to HDMI cable or adapter.
- You will need to run at least macOS Mavericks (10.9) to use multiple monitors with your Mac. Updating macOS to the latest version supported by your computer is a good idea.
- You will need enough space on your desk to accommodate all of your monitors. Make sure you have enough room to place the monitors side by side or in a configuration that works for you.
Most monitors have VESA mounts, so you can get creative with monitor mounts. Monitor mounts are affordable and upgrade mainstream monitors with swivel, tilt, and rotation. Not to mention, they’re a great way to keep your desk clear for a spacious workspace.
My Mac Only Has Thunderbolt Ports!
If your Mac has only Thunderbolt 3 or Thunderbolt 4 ports and you want to connect an additional monitor, you will need to use a Thunderbolt (or USB-C) to HDMI or DisplayPort adapter or cable. Most people in this situation opt to use a Thunderbolt or USB-C docking port, which comes with display connections and multiple connections for other peripherals.
If your Mac is an older Intel model with no Thunderbolt 3 ports, it may have HDMI, DisplayPort, DVI, or VGA ports instead. You can use a cable or adapter compatible with your Mac’s and your monitor’s ports to connect the additional monitor.
For example, if your Mac has a DVI port and your monitor has an HDMI port, you can use a DVI to HDMI adapter or cable to connect the monitor to your Mac.
How to Connect Additional Monitors to Your Mac
Now that we’re confident you have everything needed to make a multi-monitor Mac setup work, here’s how to connect additional monitors to your Mac:
- Check the back of your Mac or sides of your MacBook to find out which ports are available. Your Mac may have HDMI, DisplayPort, Thunderbolt, DVI, or VGA ports.
- Check the back of your monitors to find out which ports are available. Your monitors may have HDMI, DisplayPort, DVI, or VGA ports.
- Based on the ports available on your Mac and your monitors, choose the appropriate cables or adapters to connect the monitors to your Mac. For example, if your Mac has a Thunderbolt port and your monitor has an HDMI port, you will need a Thunderbolt to HDMI adapter or cable.
- Using the cables or adapters you have chosen, connect the monitors to your Mac. Make sure to connect the cables to the appropriate ports on your Mac and your monitors.
Once the monitors are connected to your Mac, turn on the monitors. In most cases, your Mac will automatically detect the screens and try to configure them in the best way. If that happens, you’re good to go!
If your monitor doesn’t start working immediately, we can try forcing macOS to detect it:
- At the top of the screen, In the system Menu Bar, go to Apple button > System Settings > Displays. This may be “System Preferences” on older versions of macOS.
- Hold the Option button, and Detect Displays should appear in place of Night Shift. Unfortunately, we can’t screenshot this because of how the Option toggle works, but it appears in this location.
- Use the Detect Displays button and then see whether your display is recognized. It should appear in the display diagram at the top of the window.
If your monitor still isn’t detected, try restarting your Mac with everything connected, or try connecting everything after a reboot.
Adjusting Display Settings in macOS for Multiple Monitors
Once your displays are detected and active, macOS will try and arrange them in a sensible order, but you’ll probably want to arrange them to match their physical configuration exactly:
- Go to Apple button > System Settings > Displays.
- Select Arrange.
- Use the mouse pointer to drag the pictures representing your monitors into the correct arrangement.
The final step is to adjust each monitor to have the correct resolution, color profile, and refresh rate. Note that the settings for the built-in display on a MacBook Air or MacBook Pro look different from those of external displays. You can’t adjust the resolution or refresh rate of the built-in display, but you can adjust desktop scaling to give you the full advantage of the high-resolution screen.
To adjust the display settings for external monitors in macOS, follow these steps:
- Go to Apple Button > System Settings > Displays.
- Select the display you want to modify.
Now that the display is selected, we can change different display options for that monitor.
Under Use As, you can set whether a given monitor is the primary display or an extended monitor. This is useful when you have an external monitor connected to a MacBook and want the external monitor to be the primary screen while it’s connected.
In this section, you can also mirror displays. Remember that if the two monitors have different resolutions or aspect ratios, you’ll likely end up with ugly scaling or black bars on one of the screens.
Below Use As, you’ll see a list of resolutions. It’s generally best to select the resolution that matches the native resolution of your screen.
If you use the Show all resolutions toggle, you’ll see more options, but some may not work with your monitor resulting in a black screen until the confirmation period runs out.
The Color profile section lets you select a color profile for your monitor. Usually, this defaults to the color tuning for that specific screen model. However, you can also pick another standard depending on the work you want to do. For example, many professionals working with image editing will choose the Adobe color space to get consistent color results.
The refresh rate lets you adjust how many times per second the monitor refreshes the image. In general, it’s a good idea to pick the highest available number, assuming that your monitor has correctly reported which refresh rates it accepts.
High Dynamic Range lets you activate HDR on monitors that support it. If you have HDR content that you want to play or edit, you should toggle this on for that display. However, SDR content tends to look unpleasant with HDR on, so only turn this on when you’re actually using HDR content.
Finally, you can adjust the rotation of the screen. If you have a screen that can rotate, this is useful if you want to turn it upside down or use it in portrait mode.
Once you’ve adjusted the settings for each screen to your liking, you can close the window. Settings will remain the same each time you connect these displays until you change something.
How Many External Displays Can You Attach?
While most people are happy to have a dual-monitor setup, plenty of folks are embracing the “battle station” approach and setting up numerous monitors to make their workflow easier. Before you go out and buy a pile of monitors, you should know there’s a limit to how many external displays you can connect to your Mac.
- If you want to know how many monitors your Mac supports, go to Apple Menu > About This Mac, then copy your serial number to the clipboard.
- Head to Apple’s Tech Specs website, select the Search Tech Specs bar, and paste your Mac’s serial number into the provided space. Then select Search.
- Select your model of Mac in the results.
- Under the specs for your Mac you’ll find the maximum number of supported displays for that model.
Some older Macs may not even support dual displays, so it’s important to check before you spend any money!
Using Your iPad As An External Display
While (excluding the Mac Mini) M1 and M2 Macs officially only support one external display, there is one way to get a third display. The latest versions of macOS and iPadOS support SideCar, allowing your iPad to work as an extended display and not count toward the display limit.
There are a few requirements:
- A compatible Mac and iPad.
- At least macOS Catalina and iPadOS 13.
- An (optional) cable to connect your Mac and iPad.
- Both devices must have Bluetooth turned on.
- Both devices must be signed in to the same Apple ID.
As long as the requirements are met, you should see your iPad as an option under Displays when you select the + dropdown menu.
Just choose to Extend or mirror to the iPad, and after a few seconds, the iPad should show your macOS desktop. By and large, you can now treat the iPad the same as any other external display.
Need Even More Monitors? Try DisplayLink!
DisplayLink is a technology that allows you to connect additional monitors to your Mac using a USB or Thunderbolt connection. If you want to use DisplayLink with your M1 chip-based Mac to exceed the monitor limit, you will need to use a DisplayLink-powered docking station or adapter.
To use the additional monitors with your M1 chip-based Mac, you will need to install the DisplayLink software on your Mac. You can download the software from the DisplayLink website.
