As an LED display distributor, are you always confused by frame rate and refresh rate when choosing LED displays for your projects? They sound similar, but in reality have different meanings. What they mainly determine is whether the video appears smooth. This article will help you thoroughly understand the relationship between the two and subsequently make a more ‘smart’ choice in your selections.
Understanding Frame Rate? Why is it so Important?
You can think of frame rate as the simple number of images that are refreshed per second – a video or game if you will. The speed of this refresh is almost like turning the pages of a comic book. Quality of the computer’s hardware configuration plays a large part in this; the graphics card (GPU) and the processor (CPU) are responsible for every single frame the eye sees as being ‘drawn’.
Frame rate results in all-around smoother, more stable dynamic visuals. Comparing competitive games, a 120fps graphics card will always be faster than 60fps in at least some aspects of responsiveness and small detail processing. Those near-instantaneous millisecond-type reactions that games demand are to a large extent dependent on frame rate.
What is Refresh Rate (Hz) and is it Important?
You can think of refresh rate as reading speed. It’s different from frame rate. It refers to how fast your display can “show” in one second. The biggest benefit of a high refresh rate is “silky smoothness.” Whether playing games, simply moving the mouse, or watching sports, you can clearly feel that the picture is more responsive and the movements are more fluid. That’s why gaming monitors now boast 144Hz or 240Hz, precisely to ensure that every micro-operation is reflected on the screen in real time.
When choosing a monitor, don’t just look at how powerful your graphics card is; you also need to pay attention to the screen’s refresh rate. Ideally, it should match your graphics card’s frame rate as closely as possible to avoid wasting performance.
Frame Rate (FPS) vs. Refresh Rate(Hz): What’s the Difference?
Both aim to provide some form of great viewing experience, but their respective functions are completely different. Let’s jump right in with a “spot the difference” game:
Different Origins
Frame Rate (FPS): This is the “KPI” of the graphics card (GPU). It simply does its work – rendering as many images as possible per second; that frame rate is what is measured. The source of this is inside the computer case.
Refresh rate (Hz): Determined by the monitor itself. How many times the screen refreshes per second is what this represents: a pure hardware attribute of the display device. Desktop-based, its source is external to the computer.
In short: one manages production, the other the display.
Different Functions
The frame rate determines the near physical smoothness and clarity of action. Higher frame rates lead to more fluid, less blurry fast-moving scenes.
The refresh rate takes care of stability-type smoothness. Ghosting, scrolling, and all related small/mid-size movements are all improved by a higher refresh rate.
Different Bottlenecks
Stuttering or any kind of lag experienced by the user is almost always a low frame rate issue – The graphics card’s performance is insufficient to generate enough frames.
Screen tearing and various forms of image misalignment are the classic low refresh rate problems; the monitor just can’t ‘keep up’.
Upgrades Different
Improving frame rate: computer/GPU hardware (or settings as a secondary option).
Improving refresh rate: better monitor, period.
Frame Rate (FPS) and Refresh Rate (Hz): How to Choose for Different Uses?
Simply put, the choice depends entirely on what you’ll be using your computer for. After reading the following, you should have a better understanding.
Making Videos and Creating Content
If you are an editor, an animator, or a streamer, then you’ll have to worry about both frame rate and refresh rate. Because when editing regular 24 or 30 frame rate video, A 60Hz screen is basically enough. However, if you frequently work with 120fps slow-motion footage, and then you’ll need to be able to pair it with a 120Hz or 144Hz screen. Only in this way can you preview by dragging the timeline, and then you can see each frame clearly. This is why many professional editors use high refresh rate monitors.
Gaming
When playing competitive games, frame rate is the primary focus. A higher frame rate means faster image processing, especially important for competitive games where players are often willing to sacrifice some graphics quality for a satisfactory frame rate. Ideally, this should be paired with a monitor with a high refresh rate.
Average Users
If you only do daily office work, browse the web, and watch videos, you’ll generally prioritize refresh rate. A standard 60Hz refresh rate screen will handle scrolling through web pages and switching windows without any problems.
How to Choose Frame Rate Vs Refresh Rate in LED Displays?
It mainly depends on what kind of content your LED display needs to show， and where else it is used.
Playing Regular Content and Videos
Indoor LED displays are generally used in conference rooms; they don’t have high requirements for content and video. Generally, a graphics card capable of 30 to 60 frames per second and a screen with a 60Hz refresh rate are suitable; it can achieve the desired effect without any lag during playback.
Playing Fast-Paced Content and Videos
If it’s an LED video wall used for watching sports events or playing games. This requires a frame rate of 60 to 144 frames per second and a refresh rate of 120Hz or 144Hz, which ensures smooth and clear playback of fast-moving scenes.
Live Streaming or Real-time Interaction
Immersive LED displays and LED floor tile screens are used for live streaming or interactive purposes; they are usually quite large. The video footage that needs to be processed is quite complex.LED displays of these types require frame rates of 60 to 120 frames per second and refresh rates of 120 to 240 Hz. This prevents video footage from flickering, blurring, or shaking due to insufficient bandwidth.
Outdoor Advertising
Outdoor LED displays are mainly used for rotating advertising images or slow-motion videos. Generally, a frame rate of 30 to 60 frames per second and a refresh rate between 60 Hz and 120 Hz are selected. This will basically ensure smooth playback and also save costs.
Frame Rate or Refresh Rate, Which is Better?
Honestly, there’s no absolute right or wrong choice. They’re like a pair of chopsticks; both need to be used together.
If your monitor is high-end (high refresh rate), but your graphics card can’t keep up (low frame rate), then the screen has all the potential but fails to display enough ‘new’ images – the power of the screen is wasted.
Conversely, a powerful graphics card (high frame rate) placed before an ordinary monitor (low refresh rate) will see most, if not all, of the carefully drawn images it produces wasted. The monitor simply cannot display what the card has created.
Conclusion
The detailed explanation of both frame rate and refresh rate provided within this article allows for a clear understanding of them being two near-constant pillars of any visual experience. The specific differences, and to a point all working principles, between the two are something that should be at least partially known. Making the ‘wisest’ possible decision when choosing LED displays, monitors, graphics cards, or simply configuring various types of equipment will all benefit from this understanding; perfect frame presentation is the end goal.

FAQs:
Q1. Are Frame Rate (FPS) and Refresh Rate (Hz) the Same Concept?
Not at all. Frame rate refers to the speed at which a computer’s graphics card outputs those images. The refresh rate is the speed the display device itself updates said images. Cooperating is one thing, but having both concepts be identical in function is not. Each serves a completely different purpose.
Q2. How does Variable Refresh Rate Solve Screen Tearing?
Screen tearing occurs when the speed at which the graphics card delivers the image and the speed at which the monitor refreshes the image are not matched. Newer forms of variable refresh rate – G-Sync being the prime example, FreeSync being a more accessible alternative – solve this problem. Real-time matching of some sort is what these technologies aim for. Quick rendering by the card leads to a quick refresh from the monitor; slow rendering leads to a slow refresh. Matching the two in any capacity removes the ‘tearing’ effect.
Q3. When Frame Rate (FPS) and Refresh Rate (Hz) don’t Match?
Using a 120fps graphics card to match a 60Hz monitor is a prime example; many, if not all, images will fail to display completely.
A higher refresh rate than the frame rate itself is the more common scenario – using said 144Hz monitor with only 30fps output being a perfect case study. Continuous repeating of that single frame(s) occurs, stuttering being the end result.
Q4.What’s the best way to match frame rate and refresh rate?
Ideally, they should be perfectly matched. This means that if the monitor is 60Hz, the graphics card should stably run at 60 frames per second.
