Analysis: the reason why the led display only shows a part

We often have the problem that only part of the led display works and the other part is completely dark and shows nothing. what is the root cause? Please follow our technical engineers to start investigating the reason why the led display is only partly lit: The led display is only partly lit 1. Check whether the power supply of the display is fully powered on (check the black part, and whether the red light of the receiver card is on). 2. Check whether the signal transmission is discontinuous (mainly by checking whether the green light of the receiving card is flickering).

3. Check whether the display area exceeds the maximum resolution of the sending card (such as Linsn TS802, a single network port supports a maximum of 1600 * 400, a dual network port supports a maximum of 2048 * 640, and if dual cards are cascaded, the maximum load is 2048 * 1152); 4. Check whether the pixel of the video source is lower than that of the LED display; 5. Check whether the resolution of the computer is lower than that of the sending card (the default resolution of the sending card is 1024*768); 6. Check the setting of the sending card, Such as TS802, whether its DIP switch is in the correct state; 7. Check whether the output pixels of the video processor are lower than the screen; 8.
