In the case of a general meteor shower card, the resolution of the DVI interface is 1024*768. The cause of the LED display screen may also be a problem with the graphics card, or a driver problem. Try to unplug the network cable of the receiving card behind the display and press the debug button on the receiving card to see if the screen scan is normal.
