I am getting flicker on my set up. I have 7 64x32 P3 chained together. Using a Pi 3 running Raspbian OS Lite. I have tried using the command --led-limit-refresh to manipulate the refresh rate, but I keep getting this message in return:
Option --led-limit-refresh=160 starts with --led- but it is unknown. Typo?
Am I missing the command on my system? Is there an alternate means of refresh rate control?
