If the new type of small-pitch full-color LED display screen appears blurred after installation and power-on, it is mainly because the scan settings of the led software control card are incorrect, and the cable is incorrectly inserted.

If the screen appears blurry after a period of use, it is mainly caused by a malfunction of the control card. The damage to the chip or power supply caused by water seepage in the Planet electronic screen is the main cause of the control card failure.

To solve this problem, please try to connect a DVI interface monitor to see if the DVI output port of the graphics card is normal. In addition, the reason why the small-pitch full-color LED display is not clear may also be related to the graphics card and the driver. If there is a problem with the graphics card and the driver, it is recommended to try to replace the network cable of the receiving card behind the display with the debug button on the receiving card to see if the display cabinet scans normally.

Reasons for the small-pitch full-color LED display screen:

(1) Cannot display small-pitch full-color LED display: Check whether the display power supply is normal, whether there is a strong current input, and whether the input current is too small or too large.

(2) The small-pitch full-color LED display is abnormally fuzzy or unclear: check whether the parameter setting of the led control card is correct and whether the communication line is normal.

(3) Some small-pitch full-color LED displays have abnormalities, such as black screens, fuzzy screens, etc., check whether the power supply is working properly and whether the signal transmission line of the screen body is faulty.
