Display-o-tron on Pi4

Should a Display-o-tron work on a Pi4. It hangs on the initial screen before the 4 raspberries display

I have tried 2 different pi4’s and the display works fine if i put it on a Pi3

Thanks

Simon

mine works with pimoroni code ,on pi4, but the codes for the dot3k work kind of ,with issues of not lighting the whole display ,im a novice user ,so dont have answers as to why it does that …
