As shown in the figure below, change the 0 in the original DISABLE_HDMI to 1. If there is no such sentence, please add it directly, save the file and restart the system to block this picture.
Note: This method currently only supports the Raspberry Pi OS system. If there is a problem with other systems, you need to use Raspberry Pi OS to turn off the DISABLE_HDMI of Raspberry Pi 4B, and then use other systems to display it.
