Although the LED display flashing is not a big problem, it is a headache. It not only affects the quality of the playback picture, but also affects the user's mood. What is the cause of the LED display flickering? What good solution? Here are some of the information shared by the group's technical engineers. Let's take a look.
LED display flashing reason: 1. The sending card is broken. 2. The driver loader is incorrect. 3. Is the connection between the power supply and the control card shorted. 4. The Hu cable is too long or the cable is faulty between the computer and the screen. 5. The control card is broken. Check if the small light on the control card is on? If it is not bright, it will be broken. 6. The output voltage of the power supply is unstable, and the power supply with the control card should not carry too many boards.
LED display flashing corresponding solution If it is the whole screen, the picture is moving, it is generally the driver loader is wrong, re-check the driver loader, it is not possible to uninstall the reload Another possibility is that the sending card is broken. At this time, the sending card needs to be replaced. If it is irregular flashing, it is usually a system frequency problem. Replacing the system, or adjusting the setting parameters, can basically be solved! If it is a flashing state of the stars, there may be a problem with the graphics card driver, or it may be a problem with the resolution of the sending card. Another possibility is the power supply problem (insufficient power supply, information clutter, electromagnetic interference, the design of the PCB should consider the wire diameter of the power supply and signal routing, and the PCB production process. There are some improvements in the module. . If the text is flickering (there are irregular white edges around the text, irregular flashes, and the text disappears after disappearing. This is a problem with the graphics card setting. In the display properties, cancel "Show hidden under menu" and "Edge smooth transition effect". Can solve such problems.
