I have a new Pimoroni 7" Touchscreen connected to a Raspberry Pi 3 Model B V1.2.
I know the Pi3 works - it has been tested and updated using HDMI and a separate monitor. However, when I plug it into the independently powered 7" touchscreen all I get is a flashing, fading test pattern. See the attached pictures. Any suggestions?
Thanks in advance.
I’m only allowed one image. However, the test pattern flashes and fades in and out when seen live.
