显示器的刷新率是决定显示器质量的最重要指标之一。但是如何检查显示器刷新率？
仅仅(Simply)阅读标签是不够的。要确定显示器的实际刷新率是多少，您需要使用一种工具来实时检查此性能。以下是执行此操作的五个最佳在线网站。
什么是刷新率以及(Rate)为什么需要对其进行测试？
通过依次显示多个静止图像来创建屏幕上的视觉效果。这些序列通过的速度越快，错觉就越有说服力，使视频看起来更流畅。
这称为每秒帧数或FPS。但相关视频或游戏的帧速率并不是影响视频质量的唯一因素。监视器还必须能够每秒渲染那么多帧。
这就是刷新率的用武之地。简单地(Simply)说，显示器的刷新率是它每秒可以显示的帧数。刷新率越高，您获得的图像质量就越好。这就是您需要测试显示器并确定其刷新率是否足以满足您的游戏或视频需求的原因。
1.TestUFO
这是最容易运行的测试之一，也是最准确的测试之一。只需打开该网站(open the site)，让它发挥它的魔力。TestUFO将自动与您的浏览器同步并检查显示器的刷新率。结果显示在屏幕中间。
建议在运行测试时关闭所有其他正在运行的程序和浏览器选项卡，以尽量减少任何干扰。如果互联网不稳定，该工具将在底部显示警告。等到(Wait)它显示绿色“就绪”以确认结果。
TestUFO还提供其他工具来测试显示器的其他参数。例如，您可以检查显示器是否跳帧(check your display for frame skipping)，这在您对显示器进行超频时会派上用场。
2.显示HZ
简单而简约，此测试如其所说：以赫兹(Hertz)(Hz) 显示显示器的刷新率。该测试(The test)以其运行速度而著称，只需几秒钟即可为您提供结果。这比市场上大多数类似的工具要快得多。
它是称为Vsync Tester的旧工具的改进版本（对于旧设备可能仍然更好）。其准确性无与伦比，为您提供小数点后六位的刷新率，领先于竞争对手。
此工具在比较多个显示器时特别有用，因为大多数屏幕将显示大致相同的值。额外的精度允许进行更好的比较。
3.显示测试
这个漂亮的小工具可以测试您的显示器并快速确定其刷新率。虽然它只显示一个小数点的结果，但该值以秒为单位确定。
Display Test适用于大多数浏览器，包括Apple WebKit和 Mozilla 基于 Gecko 的产品，当然Chrome除外。它还具有比大多数此类工具更好的用户界面，使其易于使用和理解。
只需前往网站并点击“开始”(Go)按钮即可。测试将快速执行，并在快速拨号上显示结果。
4. 艺卓显示器测试
我们将其列在第四位，但这可能是列表中最全面的工具。Eizo Monitor Test(The Eizo Monitor Test)不仅测试显示器的刷新率，还测试有关它的所有内容。
有缺陷的像素、色距、锐度、视角——这个工具在所有重要的技术方面测试您的显示器。它也是完全可定制的，允许您选择要运行的测试，因此您可以在匆忙时使用刷新率测试。
这些特性使Eizo显示器测试成为诊断显示器问题的非常有用的资产(helpful asset in diagnosing monitor issues)。您应该不时使用该站点检查您的显示器，以确保其正常运行。
5. 每秒帧数
这个工具的工作方式有点不同。它不仅显示刷新率的数值，实际上还显示了不同的刷新率。
当您打开Frames-Per-Second时，您会看到两个球形物体在移动的背景上来回弹跳的重复动画。这些图像中的每一个都在不同的fps上运行，展示了不同的帧速率在运行中是如何出现的。
您可以根据自己的喜好修改这些数字，将每个动画设置为您想要的任何 fps。还可以设置运动模糊(Motion Blur)之类的东西，以准确衡量这些帧速率的对比情况。
哪个是测试显示器刷新率的(Monitor Refresh Rate)最佳站点(Best Site)？
如果您正在寻找可能的最佳精度和准确度，DisplayHZ就是您正在寻找的工具。它提供最多六位小数的结果，并且运行迅速。
为了更全面地了解您的显示器，您必须使用Eizo显示器测试。它将有助于测试您的设备是否存在各种视觉问题，确保其正常工作。
无论您是检查旧显示器的规格还是考虑升级到新(thinking of upgrading to a new one)显示器，刷新率都是要考虑的核心功能之一。使用这些工具，您可以确定显示器的位置。
5 Best Sites to Test Your Monitor Refresh Rate
The refresh rаte of a monitor is one of the most important metrics to determine the quality of a display. But hоw do you check the monitor rеfresh rate?
Simply reading a label is not enough. To determine what the refresh rate of your monitor is in practice, you need to use a tool that checks this performance in real-time. Here are the five best online sites for doing this.
What Is Refresh Rate And Why Do You Need to Test It?
Visuals on a screen are created by displaying multiple still images in sequence. The faster these sequences pass by, the more convincing the illusion, making the video look smoother.
This is known as the frames-per-second, or FPS. But the frame rate of the video or game in question is not the only factor in video quality. The monitor has to be capable of rendering that many frames every second as well.
This is where the refresh rate comes in. Simply put, the refresh rate of a display is the number of frames it can show every second. The higher the refresh rate, the better the picture quality you get. This is why you need to test your display and determine if its refresh rate is actually enough for your gaming or video needs.
1. TestUFO
This is one of the easiest tests to run, and also one of the most accurate. Just open the site and let it work its magic. TestUFO will automatically sync with your browser and check the refresh rate of the monitor. The results are displayed in the middle of the screen.
It’s advised to close all other running programs and browser tabs while running the test to minimize any interference. In case the internet is choppy, the tool will display a warning at the bottom. Wait until it shows a green “Ready” to confirm the results.
TestUFO also offers other tools to test additional parameters of your monitor. For example, you can check your display for frame skipping, which comes in handy if you are overclocking your monitor.
2. DisplayHZ
Simple and minimalistic, this test does what it says: display the refresh rate of your monitor in Hertz (Hz). The test is notable for how quickly it works, giving you a result in mere seconds. This is much faster than most similar tools in the market.
It’s an improved version of an older tool called Vsync Tester (which might still be better for older devices). Its accuracy is unmatched, giving you the refresh rate in six decimal points, which is leagues ahead of the competition.
This tool is especially useful when comparing multiple displays, as most screens will show roughly the same values. The additional precision allows for a better comparison to be made.
3. Display Test
This nifty little tool can test your display and quickly determine its refresh rate. While it shows results only to a single decimal point, the value is determined in seconds.
Display Test works on most browsers including Apple WebKit and Mozilla’s Gecko-based offerings, apart from Chrome, of course. It also has a better UI than most such tools, making it easy to use and understand.
Just head to the website and hit the Go button. The test will be executed quickly, showing the results on a speed dial.
4. Eizo Monitor Test
We have listed this on number four, but this is probably the most comprehensive tool on the list. The Eizo Monitor Test doesn’t just test the refresh rate of your monitor, but everything about it.
Defective pixels, color distances, sharpness, viewing angle – this tool tests your monitor on all important technical aspects. It is also fully customizable, allowing you to choose which of the tests to run, so you can just use the refresh rate test if in a hurry.
These features make the Eizo monitor test a very helpful asset in diagnosing monitor issues. You should use the site to check your monitor from time to time to ensure that it’s functioning properly.
5. Frames-Per-Second
This tool works a bit differently. Instead of just displaying the numeric value of your refresh rate, it actually shows different refresh rates in action.
When you open Frames-Per-Second, you will be greeted with a repeating animation of two spherical objects bouncing back and forth over a moving background. Each of these images runs on a different fps, demonstrating how different frame rates appear in action.
You can modify these numbers to your liking, setting each animation at any fps you want. Things like Motion Blur can also be set to get an accurate gauge of how these frame rates look in comparison.
Which Is the Best Site To Test Your Monitor Refresh Rate?
If you’re looking for the best precision and accuracy possible, DisplayHZ is the tool you are looking for. It provides results up to six decimal places and works quickly.
For a more holistic look at your monitor, you must use the Eizo monitor test. It will help in testing your device for all sorts of visual issues, making sure it is working properly.
Whether you’re checking the specs of an old monitor or thinking of upgrading to a new one, the refresh rate is one of the core features to consider. And with these tools, you can determine where your display stands.
