1. What are the quality requirements for LED display screens for synchronous live broadcasting?
The quality requirements for LED display screens for synchronous broadcasting live broadcasts mainly include the following aspects:
1). Use a synchronized player
This is the most important point. If you want to use your LED display screen to broadcast a football game live, you must use a synchronized player. Asynchronous broadcasting cannot be performed.
2). High دقة
High resolution can present more delicate and clear images and text, which is essential for the display of details in live content.
Especially when it is necessary to display product details, anchor expressions or sports scenes, high resolution can ensure that the audience has an excellent visual experience.
Generally speaking, the resolution should be at least 2K, and even 4K or higher resolution display screens can be considered. This will not only clearly display the live content but also ensure the clarity and fineness of the image.
3). High سطوع and contrast
- سطوع:
The brightness of the LED display needs to be determined according to the installation environment. For indoor environments, a brightness of 600 — 800cd/m² is more appropriate; in outdoor environments, it needs to reach 1500 — 3000cd/m² to ensure that the picture is still clearly visible under strong light.
High brightness helps to overcome the interference of ambient light and maintains the clarity and color reproduction of the picture.
- مقابلة:
Contrast refers to the ratio of the brightest area to the darkest area when displaying an image. High contrast can enhance the layering and three-dimensional sense of the image, making the picture brighter and the colors more vivid.
Generally speaking, the higher the contrast, the better, but the comprehensive influence of other parameters must also be considered in the actual selection.
4). Wide زاوية الرؤية
A wide viewing angle can ensure that viewers in different positions can see clear and consistent pictures, avoiding color and brightness deviations. This is especially important for large live broadcast rooms or occasions with a large number of viewers.
Usually, LED display screens should have a large viewing angle (such as horizontal and vertical viewing angles of more than 160°) to ensure that viewers can get a good viewing experience from all angles.
5). High معدل التحديث
High refresh rate can reduce the flickering and smearing of the picture, making the dynamic picture smoother. This is especially important for showing fast-moving scenes or product demonstrations.
Generally speaking, the refresh rate of LED display screens should reach or exceed 120Hz or even higher (such as 144Hz, 165Hz, etc.) to ensure that the audience can feel the continuity and smoothness of the picture when watching the live broadcast.
6). Stability and reliability
Synchronous live broadcast requires LED display screens to have high Stability and reliability to avoid failures or interruptions during the live broadcast.
Choose brands and products with reliable quality and good Stability to reduce the frequency of failures and repairs.

Then, start the computer and LED display screen, and select the signal source according to the prompts of the display screen (usually select HDMI mode).
- The connection from the video processor to the LED display is made by using a network cable:
For the application of LED display, Ethernet cables such as CAT5e or CAT6 are usually selected, as they have high data transmission rates and good anti-interference capabilities.
Plug one end of the network cable into the network port of the video processor and the other end into the network port of the LED display (or transfer through a network device such as a switch).
Make sure that the video processor and the LED display are in the same network segment so that they can communicate with each other. This usually involves setting network parameters such as IP address and subnet mask.
3). Settings
After connecting the computer and the LED display, because your LED display is a synchronous control system, your LED display will display what the computer displays.
At this time, you just need to open the live broadcast software and select the live broadcast of the football game you need to play.
4). Testing and optimization
4.1). System test:
Perform system testing before the official live broadcast, including Testing of video playback, audio output, and picture synchronization.
Ensure that all devices are working properly and compatible with each other without conflict.
4.2). Optimization and adjustment:
Make necessary optimization adjustments based on the test results, such as adjusting the settings of the playback software, changing the connection cable, etc.
Ensure that the picture is clear and smooth and the sound is clear and noise-free during the live broadcast.
