Many people do not know how to solve the problem of the LED display screen, because many people are afraid that they will accidentally touch which switch will cause the screen to become more serious. In fact, there are many reasons why the small-pitch LED display screen cannot be displayed normally. Here, the editor of Liancheng has made some correlations to the causes of the LED screen's blurry screen, and believes that the reasons are as follows:



1. If the new small-pitch LED display is just installed and powered on, most of the reasons are because the scanning settings of the LED software control card are incorrect, and the cable is not inserted correctly.



2. If it is because the screen is found after a period of use, most of the reasons are the failure of the control card. The biggest reason for the failure of the control card is the damage to the chip or power supply caused by the leakage of water from the LED screen board.



If you want to solve this type of problem, you can try to connect a monitor with a DVI interface and observe whether the DVI output port of the graphics card has a normal signal. Because the display cards of some LED display manufacturers are still very good, LCF Lighting knows that the DVI interface resolution of the general Lingxingyu card is 1024*862. In addition, the cause of the fine-pitch LED display screen may also be a problem with the graphics card and driver. If it is really a problem with the graphics card and driver, we suggest that you can try to replace the network cable of the receiving card behind the display screen with the debugging button on the receiving card to see if the display box scan is normal.
