Refresh rate has always been an important parameter in the LED display industry, and even the most concerned parameter when buyers buy LED screens. In addition to refresh rate, there are many parameters that indicate its performance, such as gray level, resolution, frame rate, and so on. To really improve the refresh rate, you need to improve the hardware as a whole, otherwise it’s just fake high refresh rate at the expense of other parameters,
In the LED display industry, regular and high Refresh Rate displays are currently generally defined as 1920HZ and 3840HZ, respectively. Sometimes referred to as 2K and 4K respectively the approximation of former.
However, in the post-pandemic era which is filled with global instability and inflation, to reduce costs, some LED display manufacturers have introduced a new LED billboard with a refresh rate of 2880HZ based on existing hardware. At the same time, they hype it as 3K to confuse 2880HZ with 3840HZ. But it’s actually fake high RF!
It still adopts the drive mode of regular RF- double latch drive.
Under normal conditions, the dual latch drive has 1920HZ Refresh Rate, 13Bit gray display and owns built-in function to eliminate ghosts, remove bad points and start under low voltage.
But by forcing the refresh rate up to 2,880 HZ, it can’t function as usual and compromises on other LED display parameters.
1.Grayscale performance reducing, especially the low gray color.
2. The data cannot be effectively processed, which greatly reduces the stability of LED display.
Because under normal circumstances, each refresh scan needs to complete the gray scale count and transfer the next row of data. But the fake high RF shortens each refresh time and interrupts the normal process.

The truly high RF products made by SandsLED use PWM drive mode. With more integrated circuit functions and algorithms, as well as natural driver chips made of larger wafers, our LED displays have improved in all aspects. In the case of the uplift of refresh rate, it still has excellent gray performance and stability.
So, if just focus on refresh rates, it’s easily to be fooled by this kind of marketing. As a professional buyer, knowing more LED knowledge is necessary for you, including the driving mode of the LED display chip, gray scale counting time, response time, data processing bandwidth, and some parameters of LED display like resolution, frame rate, scan mode and so on. They are all important factors about picking a high-quality LED billboard.
Sounds complicated, right? You can also leave it to a truly reliable and professional LED manufacturer.
