When many users install the LED display, they have clearly debugged it well, but when using or in a meeting, various situations often occur. Whiteheads are a headache, and when using or in a meeting, many small whiteboards that do not touch the large led screen will appear. What is displayed on the screen?


Liancheng Xiaobian brings you to see the reasons and solutions for the dissatisfaction of the LED screen:


1. Resolution problem


As long as you increase the resolution a little bit, you can display it in full screen, first click on an empty space on the desktop, and then right-click the screen resolution setting. Solved by adjusting the screen's better resolution.


2. Graphics card driver problem


There is no graphics card driver or there is a problem with the driver for the large-screen led display card, which will also cause the problem that the computer screen cannot be displayed in full screen. The specific operation is to install the driver or driver wizard after downloading, and update the graphics card driver.


3. The screen has black borders and is not satisfied with the screen



This depends on whether a professional player is used, such as pictures and videos. When we use the computer's own playback software to play, there must be a frame. If we want to eliminate the frame, we must use a frameless player. There are several players that can eliminate borders (vmix, P1 experience version, Apple system PVP), these are free and easy to operate.

4. Player input resolution


If you are using a professional player and there are black borders, it depends on whether the output resolution of the player reaches the best state, usually 2k output is 1920*1080 resolution, and see if there is any change. Second, to see if the input and output resolutions on the processor side are adjusted to appropriate parameters, it may also be the cause of the black borders.


5. Adjust the file display ratio


If the ppt is played on the large led screen, we can achieve the full screen state by adjusting the proportion of the ppt. Usually our full-screen playback ratio is 16:9, and all PPT design ratios can achieve this ratio. If it is a square screen, 16:9 will be pulled and deformed. If it is not this ratio, it will not be able to reach the full screen state. It is time to adjust it with the help of the processor.


Other reasons for the incomplete display of the LED display:


The wiring is rough, which is mainly manifested in the poor quality of the power supply line, and the uneven current intensity of each line, resulting in uneven current intensity for the LED luminous characters.

2. Electric leakage phenomenon, or when the circuit is not routed properly, the joints are not properly connected, resulting in leakage of electricity, resulting in missing font strokes.

3. The lines are connected in series, the main line drawn from the power supply is connected to the first word first and then the second string. When the latter, the current passing through will become smaller and smaller, so the smaller the current, the lower the brightness. It is recommended that the lines be connected in parallel, especially when the font size is large.

4. The models of LED lights are different, the models of lights produced by different manufacturers are different, and the luminous effects are also different. There is also the use of low-quality LED light sources. In these cases, the brightness of the luminous fonts will be inconsistent.

5. The light sources are unevenly arranged, and there are too many LED lights along the way. Consult the manufacturer of the lights for each string. The arrangement density of the light sources should be operated according to the requirements of the seller, and cannot be arranged arbitrarily.


6. Transformer power should be selected according to the size of the LED light-emitting font. The power of the transformer is too small and the luminous intensity is not enough.


The above are the reasons and solutions for the incomplete display of the LED display. Warm reminder, if you buy an LED display, it is recommended to buy a powerful LED display manufacturer, such as Lianchengfa, etc. Generally, the display products produced by large manufacturers have already set the relevant settings, and these situations generally do not occur.
