Elecrow 4 inch IPS 800x480 touch screen
I had a few questions about the Elecrow 4 inch IPS 800x480 touch screen (RR040I). Will the second HDMI port on the Raspberry Pi 4 still work and output video while the first HDMI port is connected to your screen with touch-enabled?
Comments
please help me
Regarding the two HDMI displays, both HDMI ports can be used as output displays, please refer to the following URL for the specific tutorial.
