-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).
