The value to pass 'setPanelBrightness' is the RGB Matrix's pixel width or less. i.e. Approx. 50 or lower. Values greater than 60 can cause ghosting it seems on some panels.
The value to pass 'setPanelBrightness' is the RGB Matrix's pixel width or less. i.e. Approx. 50 or lower (for a 64 pixel wide panel). Values greater than 60 can cause ghosting it seems.
HOWEVER, by default the library uses a brightness level of '16' so there's really no need to call .setPanelBrightness, unless you specifically want a super bright display.
Summary: setPanelBrightness(xx) value can be any number from 0 to MATRIX_WIDTH-1. So if you are chaining multiple 64x32 panels, then this value may actually be > 64 (or you will have a dim display).
