如何找到Mac的屏幕分辨率
The resolution (in pixels by pixels) of your Mac’s display determines how much information you can fit on screen and how sharp the image is, so it’s important to know. If you run a full-screen game or application at native resolution, the image will look its best, so here’s how to find out what it is.
Mac显示器的分辨率(以像素为单位)决定了屏幕上可以容纳多少信息以及图像的清晰度，因此了解这一点很重要。 如果您以本机分辨率运行全屏游戏或应用程序，则图像看起来将是最好的，因此下面介绍了查找图像的方法。
First, click the Apple icon in the upper-left corner of the screen, and select “About This Mac.”
首先，点击屏幕左上角的Apple图标，然后选择“关于本机”。
In the window that pops up, click the “Displays” tab.
在弹出的窗口中，单击“显示”选项卡。
On the next screen, you will see information about the display (or displays) you have built-in or attached to your Mac.
在下一个屏幕上，您将看到有关内置或连接到Mac的显示器的信息。
The screen resolution is the set of numbers listed in parenthesis just after the size of the display. For example, the listing here says “27-Inch (2560 x 1440)” which means that the Mac in this image has a 27-inch display with a 2560 x 1140 pixel resolution.
屏幕分辨率是紧跟在显示尺寸之后的括号中列出的数字集。 例如，此处的清单显示为“ 27英寸(2560 x 1440)”，这意味着该图像中的Mac具有27英寸的显示屏，分辨率为2560 x 1140。
(Note that “About This Mac” always show the native (ideal) resolution of the display regardless of the resolution settings in System Preferences.)
(请注意，“关于本机”始终显示显示器的原始(理想)分辨率，而不管“系统偏好设置”中的分辨率设置如何。)
If you have more than one display attached to your Mac, you will see all of them in this window. Here’s an example. With an external display, you’ll find its native resolution listed just under its name.
如果Mac上连接了多个显示器，则在此窗口中将看到所有这些显示器。 这是一个例子。 通过外部显示器，您会发现其本机分辨率恰好在其名称下方列出。
Now that you know your display’s native resolution, you can use it to run games at the best possible quality, find desktop wallpapers that fit your screen exactly, and more.
既然您知道了显示器的原始分辨率，就可以使用它以最佳质量运行游戏，查找完全适合屏幕的桌面墙纸等等。
If you need to adjust your resolution settings, About This Mac makes it easy. Just click the “Displays Preferences” button in this window, and you’ll be taken directly to “System Preferences” where you can tweak your display settings to fit your needs.
如果您需要调整分辨率设置，“关于本机”将使操作变得简单。 只需单击此窗口中的“显示首选项”按钮，您将直接进入“系统首选项”，您可以在其中调整显示设置以适应您的需求。
