1920Hz vs 3840Hz vs 7680Hz: A Comparison And Guide

1. Introduction

All display devices have a refresh rate. It is a technical feature of a display device that affects the product’s clarity, visual and thorough performance. And if you’re no digital display guru, it is wise to know about refresh rate firsthand, especially if you’re considering getting a display device.

Some of the devices with this feature include the television, phone, laptop, computer monitor, tablets, and a lot more.

Now, to let you understand it further, let’s go ahead and learn more about the refresh rate and its various levels.

2. What Is The Refresh Rate?

Refresh rate is the frequency with which the image on a computer monitor or similar electronic display screen is refreshed. It is measured in Hertz or Hz.

The refresh rate of your display refers to how many times per second the display can draw/ refresh a new image; therefore, the faster it goes, the more precise the image becomes. And the faster refresh rate means a higher number or level. In a narrow sense, a better refresh rate comes in a higher number, such as 1920 Hz, compared to 720 or 480 Hz.

How can we differentiate a device with a lower or a higher refresh rate? A soft or poor refresh rate is evident by simply looking at the device’s screen, such as the LED screen, and noticing factors like; flickers, mosaics, black lines, unpure white, and imbalanced color distribution.

On the other hand, a reasonable refresh rate is characterized by a smooth and vivid image display, flicker-free images or videos, and a good color display. A higher refresh rate also affects the vividness and sharpness of the image displayed, but it is not the refresh rate that should be blamed in cases of unclear resolutions.

Alongside the refresh rate, a good LED screen or LCD screen is also characterized by a proper combination of grayscale, contrast, brightness, and more.

3. The 1920Hz, 3840Hz, And 7680Hz: A Comparison

Today, like brightness and resolution, the refresh rate has also reached a higher number, making LED and LCD screens more digitally competitive in the market.

Before, refresh rates only ranged from 60 Hz to 720 Hz, and often TVs, for example, are characterized by a shorter lifespan due to sudden and quick damage to the screen. It is, perhaps, caused by a poor refresh rate that the display gradually and continually deteriorated over time. And usually, when a display device shows insufficient display capacity, we replace or avoid it.

From the previously standard 60Hz, 120Hz, 144Hz, and 240Hz refresh rate has reached 1920Hz, 3840Hz, and 7680Hz, the highest by far. Knowing that refresh rate dramatically improves your viewing experience, it is essential to understand how and when to apply the 1920Hz, 3840Hz, and 7680Hz refresh rates.

• 1920 Hz

A device such as an LED screen with a 1920 Hz refresh rate means it refreshes the image 1920 times in a second. This is considerably high and makes a powerful image display. It results in clear, vivid, and pure details on the screen.

A 1920Hz refresh rate dramatically enhances the image quality. It contributes to the clarity and contrast of the image and smooth and long-time viewing. Some devices to which you can apply a 1920Hz are LED screens for indoor and outdoor, advertising, 3D, naked-eye LEDs, LCDs for gaming monitors, etc.

• 3840 Hz

The 3840 Hz is applied to most LED screen types, including the flexible, transparent display ball, rental LED screen, LED posters, and LCDs for gaming laptops or computers. In YUCHIP, most LED screen products and solutions have a 3840 Hz refresh rate capacity.

LED and LCD screens that support 3840Hz are considered industry-leading and have high performance.

• 7680 Hz

The 7680 Hz refresh rate best suits XR LED screens and LED displays for broadcasting. With this highest refresh rate level, it ensures to give you ultimately have vivid, clear, flicker-free, best-quality, and smooth images/ videos transition. What makes this highest refresh rate possible also is the equipment used in creating and manufacturing the whole device.

In the case of LED screens such as an XR, a 7680 Hz is achievable through suitable hardware, high-quality driver IC, PCB designs, and software. In addition, a 7680 Hz LED screen eases filming as it firmly suits the requirement for camera shooting. As a result, it dramatically helps film editors. They can cut quickly, compress and finish a movie without needing to edit, put effects, and animate.

In choosing which of the refresh rates fits your project or device requirement, it is also essential for you to know how to refresh rate will affect your project results.

Apart from that, please also note that LED and LCD screens with a higher refresh rate also mean better material quality and equipment and a higher price. On a side note, you’ll surely achieve a great viewing experience and quality if you invest in a worthwhile device with a high refresh rate.

4. How To Increase Refresh Rate?

There are many ways to achieve a higher refresh rate if your device has a poor one or is experiencing deterioration in its refresh rate performance. Here are a few.

1. Firstly, check the hardware or driver IC. If your current doesn’t support a higher refresh rate, it’ll surely keep your LED screen in its low performance. The best thing to do is replace them with models supporting the high refresh rate you desire.
2. Check the PCB design or change the scan mode. You may also increase the driver IC number in the device to further support functions and processing ability.
3. Use premium and firm driver IC for your product, such as ICN2153 and MBI5252. However, installing these devices into the product without further knowledge about it could damage the device. So, it is best to contact your provider or hire a skilled person to perform the task.
4. The software you also use dramatically affects the refresh rate capacity of the LED screen or any display device. Some software has minimal options and features, which disables a higher power for the device.
5. Make sure to check whether the refresh rate displayed on the device’s manual is legit or not. How do you do it? An easier way to check it is through a DSLR or any digital camera. It is to see whether there are any flickers or black scan lines that we cannot see with the naked eye. By knowing the actual refresh rate of the device, you’ll have the choice to increase it further or not.

5. Conclusion (1920Hz,  3840Hz, 7680Hz)

Refresh rate contributes significantly to all display device attributes. And not to confuse it with frame rate since these two are different but often referred to the same.

The 1920Hz, 3840Hz, and 7680Hz are high refresh rates that will surely give you premium display quality. However, they also have specific applications for where to use them. Above all, balanced parameters that match the environment and your project requirement should always come on top.
