Can you help me with were to look for solving this problem. Thank you. Result with ./led-image-viewer --led-rows=60 --led-cols=120 --led-gpio-mapping='adafruit-hat-pwm' --led-slowdown-gpio=3 jp.png

120x60 LEDs SMD P2. size is 240x120mm

https://www.aliexpress.com/item/32961595666.html here is full information

The troubling spec is: Moudle Scan | 30scan

(you may share issues with the recent 40x20 reference, both being non powers of 2 columns)

Try this flags in the command:

./led-image-viewer --led-rows=60 --led-cols=120 --led-gpio-mapping='adafruit-hat-pwm' --led-slowdown-gpio=2 --led-multiplexing=0 --led-parallel=1 --led-pwm-bits=1 --led-pwm-dither-bits=2 --led-scan-mode=0 jp.png

[ostap-dm]

This is output result

So, none of the advises works. Is there any other ways to solve this problem?

[ostap-dm]

That's how sudo ./demo -D0 --led-cols=120 --led-rows=60 looks on my panel

Looks like you're getting close and might need to do a little bit of position mapping.

I gave up on it and bought module for using such led matrix. It turned out that it has 1/30 scan On Jul 6, 2019, 10:55 PM -0400, Henner Zeller notifications@github.com, wrote:
