My display has dim red LEDs or has odd output
Check that you have plugged in a good 5V 10A+ power supply into the matrices. The Raspberry Pi's 5V power supply cannot power a matrix, you need a separate high current supply as well!
There are gaps and/or overlayed pixels shown on the panels
This can be caused by the Adafruit bonnet address E switch being in the wrong position for the specific panels that you are using. Power down the Pi and displays, then carefully slide the switch into the other position and then reapply power and try running the code again.
