Hi @Louis. I’m using 96x32 with 3 panels.
It works fine, until I connect the output of the first 3 panels into the next 3 to get mirroring using whatever is shifted out for ease of wiring and not having to split the original cable in 2.
Sadly, when too many pixels are on, I get this on the 2nd set of panels, mostly on panels 5 and 6 in the chain:
(as a reminder smartmatrix only knows that there are 3 panels and I rely on shifting to fill the next 3 from bits shifted from the first 3 panels)
