为了配合Windows 11/10的主题，Microsoft Office 2021/19 也遵循相同的UI概念。DPI 缩放在使用具有^{(DPI Scaling)}现代 UI^{(Modern UI)}的程序中起着重要作用。当缩放配置不正确时，模糊和模糊的内容就会发挥作用。 糟糕的显示缩放^{(Poor Display Scaling)}使程序看起来很糟糕。

每英寸^{(Dots Per Inch)}点数( DPI )缩放^(Scaling)是Windows 10/8.1中引入的关于将显示器投影到外部设备的附加功能之一。对于指定的分辨率，比如 1366×768 像素，DPI 设置^{(DPI Settings)}必须高于 100%。

^{(DPI Settings)}当您将Windows 开始屏幕^{(Windows Start Screen)}或菜单投影到投影仪时， ^(Menu)DPI 设置非常重要。如果DPI 设置^{(DPI Settings)}保持在预定水平以下，Metro磁贴将失去其魅力和流动性，并将仅显示为框。

修复 Office 程序中的模糊字体

那么如何避免Office组件的不良缩放呢？

好吧，您可以尝试禁用外接显示器，看看是否有帮助。或者您可以尝试使用兼容性^{(Compatibility)}选项。如果这些都不起作用，你可以试试这个方法。

1.打开您的Microsoft Office安装文件夹。右键单击面临缩放不良问题的Office程序的图标，然后选择属性^(Properties)。

2.现在在“属性^(Properties)”窗口中，切换到“兼容性^{(Compatibility)}”选项卡并勾选“禁用高 DPI 设置上的显示缩放”^{(Disable display scaling on high DPI settings)}。单击应用^(Apply)，然后单击确定^(OK)。

现在重新打开Office程序，你会发现它们的内容不会模糊。

您可能会发现该选项被禁用或灰显。在这种情况下，您将操纵相关的注册表设置。为此，请按Windows Key + R组合，在运行^(Run) 对话框中键入 put Regedt32.exe ，然后按^{(Regedt32.exe)}Enter打开注册表编辑器^{(Registry Editor)}。

2.导航到以下位置：

HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers

3.在此位置的右窗格中，使用Right-click -> New -> String Value。将此字符串命名为您的Office组件程序的文件位置。

例如 - 说PowerPoint， - 在我的情况下，它位于E:\Program Files\Microsoft Office\Office15\POWERPNT.EXE。

现在双击相同的字符串来修改它的值数据^{(Value data)}：

4.在编辑字符串框中，将数值数据^{(Value data)}设置为~ HIGHDPIAWARE。现在，关闭注册表编辑器^{(Registry Editor)}并重新启动机器以使更改生效。重新启动后，您不会看到Office 2013程序的缩放问题。

您也可以尝试以下方法。在Office程序选项的高级^(Advanced)部分下，检查禁用硬件图形加速^{(Disable hardware graphics acceleration)}设置，看看它是否对您有帮助。

例如。打开Outlook > File Options > Advanced > Display > Check禁用硬件^(Disable)图形加速框 > 确定。重启你的电脑。

希望有帮助。

Blurry Fonts or Poor Display Scaling in Office Programs

To match the theme of Windows 11/10, Microsoft Office 2021/19 аlso follows the same UI concept. DPI Scaling plays an important role in using programs having Modern UI. When the scaling is not properly configured, fuzzy and blurry content comes into play. Poor Display Scaling makes the programs look quite bad.

Dots Per Inch (DPI) Scaling is one of the additional features introduced in Windows 10/8.1 regarding the projection of display to external devices. For a specified resolution say 1366×768 pixels, DPI Settings must be above 100%.

DPI Settings are of important concern when you project the Windows Start Screen or Menu to a projector. If the DPI Settings remains below a predetermined level, the Metro tiles will lose their charm and fluidity and will be displayed as mere boxes.

Fix Blurry Fonts in Office Programs

So how does one avoid poor scaling of Office components?

Well, you can try disabling external monitors and see if it helps. Or you can try using the Compatibility option. If these do not work, you can try this method.

1. Open your Microsoft Office installation folder. Right-click on the icon of the Office program for which you’re facing the issue of poor scaling and select Properties.

2. Now in the Properties window, switch to Compatibility tab and put a check mark against Disable display scaling on high DPI settings. Click Apply followed by OK.

Now reopen the Office programs, and you will find that their content will not be blurry.

There may be a possibility that you may find that the option is disabled or grayed out. In such a case, you will manipulate the concerned registry setting. To do so, press Windows Key + R combination, type put Regedt32.exe in Run dialog box and hit Enter to open the Registry Editor.

2. Navigate to the following location:

HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers

3. In the right pane of this location, create a new string value using Right-click -> New -> String Value. Name this string so created as the file location of your Office component program.

For instance – say PowerPoint, – in my case it’s located at E:\Program Files\Microsoft Office\Office15\POWERPNT.EXE.

Now double click on the same string to modify its Value data:

4. In the Edit String box, put the Value data as ~ HIGHDPIAWARE. Now, close the Registry Editor and reboot the machine to make changes effective. After reboot, you won’t see poor scaling issues with Office 2013 programs.

You may also try the following. From the Office program options, under the Advanced section, check the Disable hardware graphics acceleration setting and see if it helps you.

For eg. open Outlook > File Options > Advanced > Display > Check the Disable hardware graphics acceleration box > OK. Restart your computer.

Hope something helps.
