Rpi pi4 connec RGB matrix 16x32

I want to ask about the RPI PI 4 connecting to a 16x32 RGB matrix, it appears but not fully, I still use manual jumper cables for the wiring, for the attached photo

Greetings,

Please help me

sudo ./demo -D0 --led-no-hardware-pulse --led-cols=16 --leader=32

As You're using a RPi 4, you need to use --led-slowdown-gpio=<0..4> (even 5), and as those panels (16x32) are not those sell by sparkfun (32x32) you must find --led-multiplexing=<1..18> (or new values, as this library is in continue updating)

try:
sudo ./demo -D0 --led-no-hardware-pulse --led-cols=16 --led-rows=32 --led-slowdown-gpio=4 --led-multiplexing=8 (or try from 2->others)

best regards, don't forget, post a video or picture as well the command you're trying so we can diagnose the problem
