LED display flashing is annoying, solution push

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 flashing? Is there any good solution?

LED display flashing reason

1. The driver loader is incorrect.

2. The network cable between the computer and the screen is too long or the network cable is faulty.

3. The sending card is broken.

4. The control card is broken. Check that the small light on the control card is lit or not. If it is not lit, it will be broken.

5. Is the cable between the power supply and the control card shorted?

6. The output voltage of the power supply is unstable, and the power supply with the control card does not have too many boards.

LED display flashing corresponding solution

1. If the whole screen is blurred, the picture is twisted, it is generally the driver loader is wrong, re-check the driver loader, it is not possible to uninstall and reload.

2. Another possibility is that the sending card is broken. At this time, the sending card needs to be replaced.

3. 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). When designing the PCB, consider the wire diameter of the power supply and signal traces, and the PCB production process. There are also some improvements in adding more capacitors to the module.

4. If the accompanying text is flashing (there are irregular white edges around the text, irregular flashing, and disappear after the text disappears), this is a problem with the graphics card setting. In the display properties, cancel “Show hidden under the menu”, “Edge smooth transition” “Effects” can solve such problems.
