如果您一直在跟踪智能手机市场，那么一段时间以来，显示器的高刷新率(High Refresh Rate)一直是人们谈论的话题。类似地，显示器刷新率在 PC 和笔记本电脑(Laptop)市场中一直存在，但现在 Windows 11 原生支持它。在这篇文章中，您将了解新的动态刷新率(Dynamic Refresh Rate)功能在 Windows 11 中的工作原理。
什么是动态刷新率(Refresh Rate)？为什么它很重要(Important)
刷新率，简单来说，就是显示器更新屏幕图像的频率。(Rate)刷新率越高，滚动体验和游戏体验就更上一层楼。它提供逼真的运动，因为您不会看到任何滞后，即想象一个球突然从一个地方改变位置到另一个地方，它应该缓慢移动以便让您看到预期的运动。
另一方面，如果应用程序或游戏不支持动态刷新率，当Windows可以更改显示器的刷新率时，(Windows)动态刷新率(Dynamic Refresh Rate)也可以帮助节省电池电量。
新的动态刷新率(Dynamic Refresh Rate)功能在Windows 11中如何工作(Windows 11)
在Windows 11中，动态刷新率(Dynamic Refresh Rate)功能允许它根据应用程序和您在 PC 或笔记本电脑(Laptop)上的活动在较低和较高的刷新率之间无缝切换。它们都可以确保您获得更好的体验并降低功耗。固定的刷新率只会导致电池寿命缩短。
因此，例如，如果您正在使用电子邮件、阅读文档，DRR将使用 60 Hz 显示。一旦你开始高速滚动，刷新率就会跳到 120Hz，提供比 60Hz 更平滑的滚动。它也适用于着墨和触感即时和光滑。但是，它不适用于Gaming，至少目前还没有。
要体验DRR，您需要拥有一套正确的硬件。这包括支持可变刷新率 ( VRR ) 和至少 120 Hz 的显示器、支持它的图形驱动程序以及启用Windows 11的支持。不过，这仍是一项正在进行的工作，微软(Microsoft)将继续扩大对各种游戏和应用程序的支持。
在支持它的笔记本电脑(Laptops)上，您可以通过转到System > Display > Advanced Display.
将有一个刷新率部分允许您更改它。但是，您不需要更改它，而是让Windows 11管理它。
目前，看到此功能的用户可以通过Microsoft和Adobe Apps体验此功能。应用列表包括：
- 墨迹更流畅：Microsoft Office、Microsoft Edge、Microsoft Whiteboard、Microsoft Photos、Snip & Sketch、Drawboard PDF、Microsoft Sticky Notes、Adobe Acrobat、Adobe Illustrator、Microsoft To-Do、Ink等。
- 更流畅的滚动：Microsoft Office
动态刷新率(Dynamic Refresh Rate)的最低要求(Requirement)
要使用DRR，您需要一台配备支持可变刷新率(Refresh Rate)( VRR ) 且刷新率至少为 120 Hz 的显示器的笔记本电脑。
此外，DRR需要支持它的图形驱动程序 ( WDDM 3.0 )。
如何在笔记本电脑(Your Laptop)或 PC上查找显示驱动程序版本(Display Driver Version)
- 点击开始按钮
- 输入(Type)dxdiag 并在出现时单击启动
- 切换到显示(Display)选项卡并找到驱动程序(Drivers)框
- 检查(Check)版本号和驱动程序(Driver)型号
如果它们与所需的版本匹配，它将起作用；否则，您需要等待通过Windows Update提供的更新。微软(Microsoft)正在扩大对更多OEM(OEMs)的测试，希望我们能很快看到它们在 10 月 5 日左右推出(October.5)

如何在Microsoft Office中获得(Microsoft Office)更流畅的滚动(Smoother Scrolling)和墨迹书写(Inking)？
这适用于Office Insiders，您可以通过转到 Options > Experiment > Flight Assignments and Overrides 检查您是否将Microsoft.Office.AirSpace.InteractionTracker4Support 设置为 true。(Microsoft.Office.AirSpace.InteractionTracker4Support set to true. )如果没有，您需要选择加入Office 预览体验(Office Insiders)成员。
如何检查我的笔记本电脑是否支持 VRR(My Laptop Supports VRR)？
打开 设置(Settings)，然后选择 系统(System) > 显示(Display) > 图形(Graphics) > 默认图形设置(default graphics settings)。查找名为 Variable refresh rate的部分。如果此部分未出现在此页面上，则表示您的笔记本电脑不支持VRR。

支持外接显示器吗？
遗憾的是，没有。DRR仅适用于笔记本电脑(Laptops)。目前令人失望，因为微软(Microsoft)只针对高端笔记本电脑。

平滑上墨是否适用(Does Smooth Inking Work)于任何笔(Any Pen)？
不，最好在Windows上使用兼容的笔；使用DRR，您可以获得最流畅、最快的墨水。您还需要Microsoft Office的支持。
Apple的硬件已经支持这一点，Windows 也该支持它了。虽然如果您使用的是较旧的硬件，这不会有任何区别，但那些拥有高休息率监视器的人肯定会喜欢这个。但是，该支持并未扩展到游戏和外接显示器。这不是很让人放心。我希望将来可以解决此问题。
How does Dynamic Refresh Rate feature work in Windows 11
If you have been trackіng the smartphоne market a little bit, High Refresh Rate for displays has been the talk of the town for some time. On similar lines, Monitor Refresh Rate has been there in the PC and Laptop market, but now Windows 11 supports it natively. In this post, you will learn hоw does the new Dynamic Refresh Rate feature work in Windows 11.
What Is Dynamic Refresh Rate? Why Is It Important
Refresh Rate, in simple words, means how often the display updates the onscreen image. The higher the refresh rate, the better the scrolling experience and gaming experience get into another level. It delivers realistic motion because you will not see any lag, i.e., imagine a ball suddenly changing position from one place to another, which should have slowly moved to allow you to see the movement as expected.
On the other hand, Dynamic Refresh Rate can also help save battery when Windows can change the refresh rate of the display if the apps or games don’t support it.
How does the new Dynamic Refresh Rate feature work in Windows 11
In Windows 11, the Dynamic Refresh Rate feature allows it to seamlessly switch between a lower and a higher refresh rate depending on the app and your activity on the PC or Laptop. Both of them make sure you get an improved experience and reduced power consumption. A fixed refresh rate will only result in reduced battery life.
So, for example, if you are using email, reading documents, DRR will use the 60 Hz display. As soon as you start scrolling with high speed, the refresh rate will jump to 120Hz, delivering smoother scrolling than what you would have got with 60 Hz. It also applies to inking and touch feel immediate and smooth. However, it does not apply to Gaming, at least not yet.
To experience DRR, you will need to have the right set of hardware. That includes a display that supports variable refresh rate (VRR) and at least 120 Hz, a graphics driver that supports it, and enabled support from Windows 11. However, this is still a work in progress, and Microsoft will keep expanding the support for various games and apps.
On Laptops that support it, you can see the display setting by going to System > Display > Advanced Display.
There will be a refresh rate section that allows you to change it. However, you do not need to change it, but let Windows 11 manage it.
For now, those who see this feature can experience this with Microsoft and Adobe Apps. The app list includes:
- Smoother inking: Microsoft Office, Microsoft Edge, Microsoft Whiteboard, Microsoft Photos, Snip & Sketch, Drawboard PDF, Microsoft Sticky Notes, Adobe Acrobat, Adobe Illustrator, Microsoft To-Do, Ink, etc.
- Smoother scrolling: Microsoft Office
Minimum Requirement for Dynamic Refresh Rate
To use DRR, you’ll need a laptop with a display that supports Variable Refresh Rate (VRR) and a refresh rate of at least 120 Hz.
Additionally, DRR requires a graphics driver (WDDM 3.0) that supports it.
How to Find the Display Driver Version on Your Laptop or PC
- Click on the Start button
- Type dxdiag and click to launch when it appears
- Switch to the Display tab and locate the Drivers box
- Check version number and Driver model
If they match with the required version, it will work; else, you need to wait for an update delivered through Windows Update. Microsoft is expanding its test with more OEMs, and hopefully, we will see them coming in rather quickly as the launch is around October.5

How to Get Smoother Scrolling and Inking in Microsoft Office?
This is available for Office Insiders, and you check by going to Options > Experiment > Flight Assignments and Overrides and check if you have Microsoft.Office.AirSpace.InteractionTracker4Support set to true. If not, you need to opt-in for Office Insiders.
How to Check If My Laptop Supports VRR?
Open Settings, and then select System > Display > Graphics > default graphics settings. Look for a section named Variable refresh rate. If this section doesn’t appear on this page, it means your laptop doesn’t support VRR.

Does It Support External Display?
Sadly, No. DRR is only available for Laptops. It is disappointing for now as Microsoft is only targeting high-end laptops.

Does Smooth Inking Work with Any Pen?
No, it would be best if you used a compatible pen on Windows; with DRR, you can get the smoothest and fastest ink. You will also need support from Microsoft Office.
Hardware from Apple already supports this, and it’s about time that Windows also supports it. While it will not make any difference if you are on older hardware, but those who have a high restest rate monitor will definitely love this. However, the support is not extended to games and external monitors. This isn’t very reassuring. I hope this can be fixed in the future.
