Refresh Rate Test

Monitors’ refresh rates (Hz) measure how often they can update the image. In terms of video/games, the smoothness of the video/game is not affected by a higher refresh rate. High-refresh rate monitors also assume that the input they receive has more frames per second (fps) than they can display. Without this, the monitor isn’t doing much good.

What is the Refresh rate?

Refresh rate is easy to measure as waveforms per second, but it’s not easy to specify on a data sheet. It depends on several factors, including the time base setting, how long the record is, who triggers it, and what the waveform looks like, so vague descriptions often occur, such as “up to” or “typical.” In most oscilloscopes, the refresh rate does not appear in real-time, which is a shame since it allows the user to tweak the settings to maximize it as needed. 

The refresh rate can sometimes be confused with the frames per second from a game, but FPS refers to the content, while the refresh rate refers to the visual signal. The smoother motion will be evident with a higher refresh rate, which is essential for gaming, especially if you engage in competitive esports. While there is an argument that the eye cannot perceive fast changes, contrary to popular belief, the eye is capable of detecting them quickly.

How to calculate FPS?

A general formula to calculate FPS is as follows:

  • cn: Counter for the number of frames rendered
  • time_start: since when you started counting
  • time_now: Right now

In order to calculate the FPS, you can evaluate this formula 

FPS = cn / (time_now – time_start)

A large factor that often influences how fast the program  runs is whether it is running a debug or a release build. In general, the debug build is significantly slower. While they slow down the application a lot, they provide a great deal of additional information and checks that can help with debugging.

What Does Frames Per Second (FPS) Mean?

FPS is a unit that measures the performance of a display device in video captures and playback, and in video games. In order to measure frame rate, you need to count the images that are displayed consecutively every second. It is a common metric used to talk about the quality of a video.

Human brains are only capable of processing 10 to 12 frames per second. Any frame rates above these are perceived to be motion. FPS higher than these give the impression of smoother motion. Most full-motion videos have 24 frames per second or more.

There are different FPS rates for different video formats. Low-quality video produces smaller files on a computer.

How to use FPS Tester?

  • Go to Steam’s Settings > In-Game > FPS counter. 
  • Turn it on by selecting a location in the drop-down menu. 
  • In the corner, your frame rate will be displayed when you launch a game in the future.
  • However, you can check the High Contrast Color box to make the text more readable.

What is the purpose of the FPS?

The frame rate (FPS) is a metric used to measure performance in video capture and playback as well as video games. The Frame Per Second is a metric that measures the number of images displayed each second and is commonly used when discussing video quality.

How to test Fps score?

  • The frame rate can be found by right-clicking on the desktop and selecting AMD Radeon Settings from the menu. 
  • Then proceed as follows: Relive > Toolbar Hotkey (toggle) > Performance > Metric Options > Show Metrics. 
  • After minimizing Metric Options, maximizing Select Metrics, and turning on FPS, turn on FPS.

What is the use of FPS?

The frames per second (FPS) measure the performance of display devices in video capture and playback as well as video gaming. A frame rate is measured by the number of images displayed consecutively each second. This is a common metric when discussing video quality when it comes to video capture. You can measure your frame rate in frames per second (fps) if you are playing a game on your computer. You will see smoother video motion onscreen if you can pack more frames into one second. Low frame rates are generally apparent as choppy or slow when they fall below 30fps.

Changing the monitor’s refresh rate on Windows

Changing your monitor’s refresh rate can be done through your video card control panel or system settings.

  • “Press the Start button or Windows key to open the “Start menu.”
  • You can modify your settings on the Settings page
  • Select System from the menu
  • Please click on the display
  • Select “Advanced Display Settings”

Benefits of FPS

  • Low FPS increases input lag since even with little lag, graphics can’t display your key press until all frames of your movement have been rendered. 
  • A high FPS rate makes a game feel faster and more responsive.
  • The higher the frame rate, the smoother the gameplay, while the lower the FPS, the more choppy and slow the game looks.

Use of FPS

  • FPS is used to  measures the number of consecutive images (frames) being acquired per second. 
  • It can be a digital camera, a video camera, or a computer graphics system that is used to capture motion.
  •  You can also refer to frame rate as hertz and it is expressed in hertz units.
  •  It is capable of showing greater detail within a scene.


Frequently Asked Questions

What is a reasonable refresh rate?

There are typically four refresh rates on monitors: 60Hz, 120Hz, 144Hz, and 240Hz. Having a high refresh rate monitor does not have any negative consequences. A change from a 144 Hz screen to a 240 Hz screen will not have the same impact as a change from a 60Hz screen to a 120Hz screen. You don’t need a 240 Hz monitor for a good gaming experience, but if you can afford it, go for it.

What does Hz mean?

Hz (Hertz) is a measurement of frequency in terms of times per second.
