In this guide, we’ll compare Frame Rate vs Refresh Rate, including how they differ and why finding the right balance is crucial for different applications—especially when choosing the ideal settings for LED displays.
1. Frame Rate vs Refresh Rate: The Quick Answer
Frame rate (FPS) is how many frames a video source produces per second, while refresh rate (Hz) is how many times a display updates its image per second.
Frame rate comes from the content or playback system; refresh rate is a characteristic of the display hardware.
| Frame Rate | Refresh Rate | |
| Measured in | FPS | Hz |
| Controlled by | Content / GPU / Media Server | Display hardware |
| What it tells you | How fast new frames are produced | How fast the display updates |
| Example | 24 / 30 / 60 FPS | 1,920 / 3,840 / 7,680 Hz |
| Important for LED? | Content playback | Yes, especially for camera work |
2. What is Frame Rate?
Frame rate (FPS) refers to how many individual frames (images) your system or GPU can generate per second. It measures the creation capability of your hardware — how quickly your system can produce visual data.
(Refer to: https://en.wikipedia.org/wiki/Frame_rate)
The higher the frame rate, the more images your display device can render per second, resulting in smoother motion.
Common Frame Rate Levels
| Frame Rate (FPS) | Applications |
| 24 FPS | Movies/videos |
| 30 FPS | Video and live streaming content |
| 60 FPS | Sports, events, games, and high dynamic range content. |
| 120+ FPS | High-speed photography, games, and special real-time applications |
For an LED display, frame rate is mainly determined by the content source or media server—not the LED panel itself.
In the LED display industry, we generally use frame frequency to describe the number of frames per second (i.e., the number of times the image is updated) in a video. Common values are 50Hz and 60Hz.
3. What Is LED Display Refresh Rate?
In LED display technology, refresh rate refers to the frequency at which the LED screen updates or redraws the displayed image, measured in times per second. It is measured in Hertz (Hz).
A higher refresh rate results in less screen flicker and smoother motion (reducing motion blur), and effectively avoids the “ripple effect” or flickering that often occurs when shooting with a mobile phone or camera.
Refresh rate primarily affects the human eye’s perception and shooting results; it has no impact on the video source itself.
Why Refresh Rate Matters
In LED displays, refresh rate directly affects visual stability, image clarity under cameras, and overall viewing comfort.
Low refresh rate: May cause visible flicker or scan lines, especially under cameras.
High refresh rate: Provides stable and flicker-free images, ideal for professional use such as broadcasting, live events, and virtual production.
Common LED Screen Refresh Rates
| Refresh Rate | Typical Use |
| 1,920Hz | General signage and basic video playback |
| 3,840Hz | Events, sports, live streaming and camera applications |
| 7,680Hz | Broadcast, virtual production and demanding camera workflows |
The required refresh rate depends on the camera, shutter settings, content frame rate, and LED control system—not the refresh rate number alone.
How to Choose?
Choosing the right refresh rate depends on your application:
- For general advertising or signage, 1,920Hz is sufficient.
- For events or live streaming, 3,840Hz ensures flicker-free visuals.
- For broadcast, film, or XR virtual production, 7,680Hz+ is recommended for professional-grade performance.
4. Frame Rate vs Refresh Rate: Differences
While both frame rate and refresh rate deal with image updates, they focus on different aspects.
The frame rate is determined by the video or game content, while the refresh rate is determined by your display device.
Even if the video source has a high frame rate, if your display device’s refresh rate is low, it won’t be able to show every frame, resulting in a less smooth picture.
Summary Table for Frame Rate vs Refresh Rate
| Factor | Frame Rate | Refresh Rate |
| Unit | FPS | Hz |
| Refers to | Video/content | Display |
| Controlled by | Media server, GPU, content | LED hardware and control system |
| Main impact | Motion/content smoothness | Display stability and camera performance |
| Typical LED example | 24–60 FPS | 1920–7680 Hz |
| Can you increase it? | Depends on source/content | Depends on display hardware |
FPS tells you how fast new frames are produced. Hz tells you how frequently the display refreshes those frames.
5. How They Work Together on an LED Display
Frame rate and refresh rate are different specifications, but they work together to determine how video appears on an LED display screen.
When a high frame-rate video (such as 60Hz) is played on a low refresh rate screen, the picture may stutter, flicker, or show ripples.
When a high frame-rate video is played on a high refresh-rate screen (such as a 60Hz video played on a 3840Hz screen), the picture will be very smooth, and there will be no interference during shooting.
Example: 60 Hz Content + 3840Hz LED Display
(1) Content Source: 60 Hz
↓
(2) Media Server / Processor: Processes the video signal
↓
(3) LED Display: 3840Hz refresh rate
↓
(4) Camera / Human Eye: Sees the resulting image
The 60 FPS determines how often new video frames are produced, while the 3,840Hz refresh rate determines how frequently the LED display refreshes its output.
When you take a picture of the screen with a camera or mobile phone, A higher refresh rate screen can minimize the probability of scan lines or screen flicker.
6. Why Does Refresh Rate Matter for LED Displays?
Live Events
For concerts, sports venues, and live events, we recommend a 3,840Hz refresh rate or higher (7,680 Hz).
It helps the event LED display deliver stable images during fast-moving video and dynamic content.
Camera & Broadcasting
For filming and broadcasting, a higher refresh rate can help reduce visible flicker and camera artifacts.
However, image quality also depends on the camera frame rate, shutter speed or shutter angle, LED scan architecture, PWM, and video processor.
Virtual Production & XR
XR filming applications place higher demands on LED displays because cameras continuously capture the virtual production LED wall.
A high refresh rate, stable PWM performance, and compatible processing system are important for minimizing flicker and maintaining clean images on camera.
7. What Refresh Rate Do You Need for an LED Display??
The table below summarizes recommended refresh rates for common application scenarios.
However, the actual choice should be based on your project requirements.
| Application | Recommended Refresh Rate |
| Indoor Advertising | 3,840Hz+ |
| Outdoor Advertising | 1,920–3,840Hz |
| Concerts & Live Events | 3,840Hz+ |
| Sports Displays | 3,840Hz+ |
| Live Streaming | 3,840Hz+ |
| Broadcasting | 3,840–7,680Hz |
| Virtual Production / XR | 7,680Hz+ preferred |
- 3,840Hz is a strong choice for most events and camera-based applications.
- For demanding broadcasting, virtual production, and XR projects, 7,680Hz or higher is preferred.
The final specification should also consider the camera, processor, PWM, and scan architecture.

8. FAQs: Frame Rate vs Refresh Rate
- 1️⃣ Is frame rate the same as refresh rate?
No. Frame rate is measured in FPS and describes how many new frames the source produces. Refresh rate is measured in Hz and describes how frequently the display updates.
- 2️⃣ Is 60 FPS good for an LED display?
Yes. 24, 30, and 60 FPS are common content frame rates. The required LED refresh rate is a separate specification.
- 3️⃣ Is 3840Hz enough for an LED screen?
For many events, live-streaming, and camera applications, 3,840Hz is a strong baseline. More demanding broadcast and virtual production applications may require 7,680Hz or higher, depending on the camera workflow.
- 4️⃣ Does a higher refresh rate mean better LED display?
Not necessarily. Refresh rate should be evaluated together with scan rate, PWM behavior, processing, grayscale, color performance, and camera testing.
- 5️⃣ What refresh rate is best for filming LED screens?
For camera-based applications, 3840Hz or higher is commonly preferred, but the actual camera, shutter settings, processor, and LED module design will influence the final effect.
9. Conclusion
In summary, both frame rate and refresh rate play vital roles in delivering a high-quality visual experience.
- A high refresh rate is essential for displaying fast-changing or real-time dynamic content, such as in ads, games, or live events.
- If you’re focused on the quality of video content, especially HD or 4K video playback, a higher frame rate is critical.
Whether it’s normal video playback, dynamic gaming, or virtual productions, the right balance of frame rate and refresh rate will ensure that every frame is rendered perfectly, leaving your audience impressed.
