Comparison of 1920Hz and 3840Hz refresh rates

What is the refresh rate of an LED display screen?

Refresh rate refers to the frequency at which a screen updates its displayed content per second. The refresh rate of an LED display screen is measured in hertz (Hz). It is a key indicator of the clarity, stability, and flicker-free performance of an LED display screen.

A higher refresh rate not only provides more stable and detailed image display and reduces visual flicker but also results in faster frame rates, smoother transitions, and higher image clarity. Currently, the most common refresh rates available on the market are 1920Hz and 3840Hz.

What is 1920Hz?

1920Hz is a common refresh rate for LED display screens, indicating that the LED lights can switch on and off 1920 times per second. A 1920Hz refresh rate not only presents delicate and precise details on the screen but also enhances image clarity and contrast.

What is 3840Hz?

A 3840Hz refresh rate is twice that of 1920Hz, meaning the LED lights can switch on and off 3840 times per second. 3840Hz offers a higher refresh rate, smoother motion, and better performance, especially for fast-paced motion and content.

Comparison between 1920Hz and 3840Hz

Next, I will provide a detailed comparison of 1920Hz and 3840Hz from multiple perspectives, including technical implementation, visual experience, shooting compatibility, and display effects.

Technical Implementation

From a technical perspective, the 1920Hz refresh rate is achieved using dual-latch driver chips. Dual-latch driver chips not only significantly enhance the display’s refresh capability but also offer clear advantages in signal processing and drive capability, enabling precise control over the switching of LED pixels to achieve a higher refresh rate.

On the other hand, 3840Hz employs high-order PWM driver chips, which possess more powerful signal processing and driving capabilities than dual-latch driver chips. Each pixel’s brightness and color changes can be precisely controlled. Therefore, compared to 1920Hz, the chip technology of 3840Hz is more advanced and high-end, enabling ultra-high refresh rates and rock-solid stability.

Visual Experience

The visual experience of a 3840Hz refresh rate surpasses that of 1920Hz. As mentioned earlier, 3840Hz offers a higher refresh rate. Therefore, a 3840Hz LED display delivers lifelike, vivid, and visually impactful effects. This is particularly evident when displaying high-speed motion content, such as athletes sprinting or race car drivers speeding in sports broadcasts, where the transition between frames is extremely smooth and natural.

Not only is motion blur imperceptible, but it also significantly enhances the immersive viewing experience, making viewers feel as though they are right there at the moment. While a 1920Hz refresh rate can also deliver clear and detailed image quality, it still falls slightly short compared to 3840Hz.

Shooting Compatibility

From a photography perspective, the shooting compatibility of 3840Hz is higher than that of 1920Hz. Since the chip technology of, 1920Hz is insufficient to avoid water ripples, it is not suitable for photography or video recording. The 3840Hz refresh rate uses a PWM drive IC, which not only ensures that the image remains stable and clear during shooting but also significantly reduces water ripples.

Therefore, the 3840Hz refresh rate offers notable advantages in photography applications for LED displays. Additionally, the 3840Hz refresh rate holds immense potential in fields with extremely high image quality requirements, such as film production, movie shooting, and advertising photography.

Display Performance  

Although both 1920Hz and 3840Hz refresh rates are very high and significantly enhance display quality, the 1920Hz refresh rate is sufficient for most display needs. However, the 3840Hz refresh rate provides smoother, more stable, and more realistic images during fast-moving videos or video games, helping to reduce visual fatigue.

Product Price

Higher refresh rates require more advanced technology, more sophisticated chips, and more complex circuit designs, leading to increased costs. Therefore, LED displays with higher refresh rates are more expensive. Thus, 3840Hz displays are slightly more expensive than 1920Hz displays. If you have a reasonable budget, you can choose a 3840Hz display, as it offers more detailed and smoother image quality.

If your budget is tight, opt for a display with a 1920Hz refresh rate. It offers a high cost-performance ratio and maintains a relatively balanced trade-off between performance and cost.

Application Scenarios  

LED displays with a 1920Hz refresh rate are suitable for scenarios where cost sensitivity is high and display quality requirements are not stringent, such as indoor stage performances, billboard displays, exhibition halls, retail stores, shopping malls, and airports.

LED displays with a refresh rate of 3840Hz are suitable for scenarios requiring the display of high-speed motion or high image smoothness, such as outdoor LED billboards, large LED displays, LED video walls, film and television production sites, live broadcasts of major sports events, and esports competitions.

Application Software

Whether it’s an LED display with a 1920Hz refresh rate or one with a 3840Hz refresh rate, both require corresponding LED control software for operation. If you are unsure which control software to choose, please consult MuenLED; we have dedicated technical staff to assist you.

Screen Size

Both 3840Hz and 1920Hz refresh rates are applicable to various LED display screen sizes. However, the 1920Hz refresh rate is generally suitable for medium to small-sized indoor LED displays, while the 3840Hz refresh rate is typically used for large-sized screens.

Viewing Distance  

In LED displays, pixel pitch determines the viewing distance. The smaller the pixel pitch, the higher the pixel density, resolution, and image clarity. Whether it’s an LED display with a 3840Hz refresh rate or one with a 1920Hz refresh rate, there is little difference in image quality when viewed up close or from a distance.

Gaming Performance

In gaming, a higher refresh rate mostly results in better performance. Therefore, a 3840Hz refresh rate offers a performance advantage over a 1920Hz refresh rate. A 3840Hz refresh rate not only provides faster response times, more detailed image quality, and smoother gameplay, but also reduces motion blur in the display.

Power Consumption and Cost

Mostly, the higher the refresh rate of an LED display, the higher the power consumption and cost. Therefore, an LED display with a 1920Hz refresh rate has relatively low power consumption and is suitable for prolonged use.

However, an LED display with a 3840Hz refresh rate requires frequent updates, leading to higher power consumption and heat dissipation issues. This means that a 3840Hz display requires a more powerful power supply and cooling system, increasing costs and complexity.

Eye Comfort

From the perspective of comfort, refresh rate is one of the key factors affecting visual fatigue. As mentioned earlier, a higher refresh rate can better handle image quality, making the display clearer and smoother. In most cases, a 1920Hz refresh rate already provides sufficient clarity and detail, effectively reducing visual fatigue.

However, for users with extremely high requirements for smooth visuals, such as esports players and video editors, a 3840Hz refresh rate can further reduce visual fatigue, making the viewing experience more comfortable and improving long-term screen comfort.

Common Questions:

What factors affect the refresh rate and grayscale of LED displays?

We all know that the quality of the core components of LED displays (such as power supplies, driver chips, and LED diodes) directly impacts the visual performance of the screen. For LED display screen refresh rate and grayscale, the LED driver chip directly determines the visual performance of the display screen.
