当您使用 Windows 时，操作系统(operating system)会根据您的显示器自动设置屏幕分辨率以及显示的(screen resolution)文本和图标(text and icons)的大小。大多数时候，它在为用户选择正确的设置方面做得很好。但是，有时您想降低屏幕分辨率(screen resolution)以使屏幕上的文本和项目(text and items)更大。或者，您可能希望保持相同的屏幕分辨率(screen resolution)并调整文本和其他项目的大小。阅读本教程，了解如何在Windows 7和 Windows 8.1 中执行所有这些任务：
设置屏幕分辨率比以前更加自动化
在过去的几年里，屏幕分辨率的选择几乎总是完全取决于用户主导的试错过程，因为(trial and error process)Windows默认使用一两个低分辨率屏幕。这是一种“最小公分母”方法，可确保安装Windows的人至少能够从一开始就看到屏幕上的内容。更高分辨率的显示器是显卡制造商的工作，每张显卡都带有一个装满驱动程序的磁盘。即使在那之后，并非所有分辨率都适用于所有显示器，如果您尝试使用它们，您可能（并且经常这样做）得到垃圾或黑屏。幸运的是，Windows一直都有内置的保护措施。在Windows中，操作系统(operating system)会尝试正确识别您的显示器型号(monitor model)、纵横比和支持的分辨率。如果一切顺利，它会自动将分辨率设置为显示器支持的最大值。太好了，这意味着您在首次登录Windows后即可获得最大的可用屏幕空间。(Windows)
在继续之前，我们建议您阅读：屏幕分辨率或纵横比是多少？720p、1080i 和 1080p 是什么意思？它提供了上下文并解释了更改屏幕分辨率时需要考虑的概念。
如何进入Windows 7和 Windows 8.1中的屏幕分辨率(screen resolution)设置
在Windows 7(Windows 7)和Windows 8.1中更改屏幕的分辨率或其方向是从名为Screen Resolution的窗口完成的。您可以从控制面板进入(Control Panel)屏幕分辨率(Screen Resolution)。打开控制面板，然后转到“Appearance and Personalization -> Adjust Screen Resolution.”。该链接位于“显示”(Display)部分，如下所示。
到达那里的最快方法是右键单击或点击并按住(tap and hold)桌面上的任意位置，然后在显示的菜单中选择屏幕分辨率(Screen Resolution)。
它会打开屏幕分辨率(Screen Resolution)窗口，允许您进行更改。
多显示器设置时的(multi-monitor setup)屏幕分辨率(screen resolution)设置是什么样的
您经常会看到涉及多个显示器的设置。大多数人使用双显示器设置，但三显示器设置也越来越受欢迎。
以下是在Windows 7或 Windows 8.1中使用双屏配置时“屏幕分辨率”窗口的外观：(Screen Resolution)
如您所见，显示了两个监视器。用鼠标或手指选择其中一个屏幕，然后您可以更改其设置。(Select one)
如何在Windows 7和 Windows 8.1中更改屏幕分辨率(screen resolution)
要开始进行更改，请单击或点击标有“分辨率(Resolution)”的下拉菜单。
您可以将分辨率上下调整到您想要的任何设置。例如，如果您的显示器是 1080p 或 1080i，请记住这意味着最大分辨率为 1920 x 1080像素。但是，您可能会看到比这更高的分辨率，具体取决于您的显示器。
选择要使用的分辨率后，单击或点击(click or tap) 确定(OK)。Windows 会更改屏幕分辨率并询问您是否要保留新的显示设置。单击(Click)或点按保留更改(Keep changes)。如果您不这样做，或者如果您选择Revert，屏幕将返回到之前的屏幕分辨率。
注意(NOTE)：如果您使用的是便携式计算机，您可能没有机会更改屏幕分辨率。一些笔记本电脑/平板电脑/混合设备的屏幕具有固定的分辨率，您无法更改它。其他人允许您做出选择。
注意(Beware)Windows 8.1和 Windows 7中的小屏幕分辨率
上下移动分辨率滑块时，在其行程的某些地方，您可能会看到一条警告，如果您选择该分辨率，某些项目可能不适合您的屏幕。(Resolution)这意味着您的某些应用程序要么根本不运行，要么显示无法在可用屏幕上显示的窗口。
屏幕分辨率变化的后果
更改屏幕分辨率后，可能会出现两个问题：
- 首先，如果您增加屏幕分辨率(screen resolution)，您可能会发现视频密集型显示（例如游戏）可能会明显变慢，因为视频需要更多资源才能以更高的分辨率呈现。如果您的视频卡(video card)无法满足您正在玩的游戏的需求，就会发生这种情况。即使视频卡(video card)起着关键作用，其他硬件组件也会对体验产生负面影响。
- 其次，您可能会发现您的屏幕看起来大不相同。图标和文本的大小可能已经改变，如果您选择了极高的分辨率，它们可能会太小以至于您无法阅读。如果您像在电视上显示那样从远处观看显示器，则尤其如此。
对于减速，解决方法是更改为较低的分辨率。可能需要一些时间来尝试各种选择以获得可接受的图形清晰度和速度(clarity and speed)组合。
对于icon/text problem，有两种选择：更改为较低的分辨率，或者更改图标和文本的大小。
如何在Windows 7和 Windows 8.1中更改图标和文本的大小
在“屏幕分辨率(Screen Resolution)”窗口中，单击或点击“使文本和其他项目变大或变小(Make text and other items larger or smaller.)” 。
它会将您带到一个窗口，您可以在其中一起更改文本和图标(text and icons)。还有一个缩略图预览(thumbnail preview)，可以大致了解您进行更改后的屏幕外观。尝试单击或点击其他选项以观看预览更改(preview change)。
一旦你决定了你想要的尺寸，点击Apply。您会收到一条警告，提示您需要注销才能进行更改。关闭(Close)所有打开的应用程序并注销。
再次登录后，您会看到使用您选择的大小的文本和图标。如果仍然不正确，请再次执行该程序并尝试其他尺寸。
实验是找到最佳屏幕分辨率和文本大小的关键(resolution and text size)
在CRT显示器时代，选择不兼容的分辨率可能会导致问题。幸运的是，技术已经改进，今天的显示器和Windows操作系统是由更坚固的材料(sterner stuff)制成的。不要犹豫，尝试不同的设置，直到找到最适合您的设置。然后，在结束本教程之前，让我们知道您决定使用的屏幕分辨率以及文本大小(text size)的设置。在下面发表评论(Comment)，让我们讨论。
Change the screen resolution and make text and icons bigger, in Windows 7 & Windows 8.1
When you use Windows, the operating system automatically sets the screеn resolution and the size оf the tеxt and icоns displayed, based on what it thinks iѕ best, depending on the monitor that yoυ have. Most times, it does a good job at chоosіng the right settings for users. However, there are times when you want to lower the sсreen resolυtion to make text and іtems bigger оn the screen. Αlternatіvely, you may want to keep the same screen resolution and adjust the size of thе text аnd other items. Read this tutorial and see how to perform all these tasks in Windows 7 and Windows 8.1:
Setting the screen resolution is more automatic than it used to be
In years gone by, the choice of screen resolution was almost always entirely up to a trial and error process led by the user, since Windows defaulted to one or two low-resolution screens. It was a "lowest common denominator" approach that guaranteed that people installing Windows would at least be able to see what was on the screen from the get-go. Higher resolution displays were the job of the graphics cards manufacturers, and each card came with a disk full of drivers. Even after that, not all resolutions were appropriate for all monitors, and you could (and often did) get garbage or a black screen if you tried to use them. Fortunately, Windows has always had a built-in safeguard. In Windows, the operating system tries to correctly identify your monitor model, its aspect ratio and supported resolutions. If all goes well, it automatically sets the resolution to the maximum supported by your display. That is great, and it means that you get the maximum screen space available as soon as you log into Windows for the first time.
Before you move forward, we recommend that you read: What is the screen resolution or the aspect ratio? What do 720p, 1080i & 1080p mean?. It provides the context and explains the concepts you need to consider when changing screen resolution.
How to get to the screen resolution settings in Windows 7 and Windows 8.1
Changing the screen's resolution or its orientation, in Windows 7 and Windows 8.1, is done from a window named Screen Resolution. You can get to Screen Resolution from the Control Panel. Open Control Panel, and go to "Appearance and Personalization -> Adjust Screen Resolution." The link is found in the Display section, as highlighted below.
The fastest way to get there is to right-click or tap and hold anywhere on your desktop and choose Screen Resolution in the menu that is shown.
It brings up the Screen Resolution window that allows you to make changes.
What the screen resolution settings look like when you have a multi-monitor setup
You often see setups in which more than one monitor is involved. Most people go with a dual-monitor setup, but three-monitor setups are also increasingly popular.
Here is how the Screen Resolution window looks when using a dual-screen configuration in Windows 7 or Windows 8.1:
As you can see, both monitors are shown. Select one of the screens with the mouse or with your finger, and then you can change its settings.
How to change the screen resolution in Windows 7 and Windows 8.1
To begin making changes, click or tap the drop-down menu labeled Resolution.
You can adjust the resolution up and down to whatever setting you wish. If your monitor is 1080p or 1080i, for example, remember that that translates to a maximum resolution of 1920 x 1080 pixels. However, you may see higher resolutions than that, depending on your monitor.
After selecting the resolution that you want to use, click or tap OK. Windows changes the resolution of the screen and asks whether you want to keep your new display settings. Click or tap Keep changes. If you do not, or if you choose Revert, the screen goes back to the previous screen resolution.
NOTE: If you are using a portable computer, you may not be given a chance to change your screen resolution. Some laptop/tablet/hybrid devices screens have a fixed resolution, and there is no way you can change it. Others allow you to make choices.
Beware of small screen resolutions in Windows 8.1 and Windows 7
When moving the Resolution slider up and down, at some places on its travel, you may see a warning that if you choose that resolution, some items may not fit on your screen. It means that some of your applications will either not run at all or display windows that cannot fit on the available screen.
The consequences of screen resolution changes
Once you have changed the resolution of your screen, two problems may occur:
- First, if you increased the screen resolution, you may find that video-intensive displays (such as games) may be noticeably slower since the video takes more resources to render at higher resolutions. It happens if you have a video card that is not able to meet the demands of the games that you are playing. Other hardware components can negatively impact the experience too, even though the video card plays a critical role.
- Second, you may find that your screen looks considerably different. The icons and text may have changed size, and if you have chosen an extremely high resolution, they may be so small that you cannot read them. It is especially true if you watch the display from a distance as in the case of displaying on a TV.
For slowdowns, the fix is to change to a lower resolution. It may take some time to experiment with the various choices to get an acceptable combination of graphic clarity and speed.
For the icon/text problem, there are two choices: change to a lower resolution, or change the size of the icons and text.
How to change the size of icons and text in Windows 7 and Windows 8.1
In the Screen Resolution window, click or tap on "Make text and other items larger or smaller."
It takes you to a window where you can change the text and icons together. There's also a thumbnail preview that gives a general idea of what your screen looks like if you make the changes. Try clicking or tapping on the other options to watch the preview change.
Once you have decided which size you want, click Apply. You get a warning that you need to log off to make the changes. Close any open applications and log off.
After you log in again, you see the text and the icons using the size you selected. If they are still not right, go through the procedure again and try another size.
Experimentation is the key to finding the best screen resolution and text size
In the CRT monitors days, choosing an incompatible resolution could cause problems. Luckily, technology has improved and today's monitors and Windows operating systems are made of sterner stuff. Do not hesitate to experiment with the different settings until you find those that work best for you. Then, before closing this tutorial, let us know which screen resolution you decided to use, and which setting for the text size. Comment below and let's discuss.
