Hi,  
I followed the README files of [GitHub - hzeller/rpi-rgb-led-matrix: Controlling up to three chains of 64x64, 32x32, 16x32 or similar RGB LED displays using Raspberry Pi GPIO](https://github.com/hzeller/rpi-rgb-led-matrix) and wired the things, I can able to see the unclear text/image while trying to run following commands " sudo python image-scroller.py --led-cols=64 --led-rows=32 --led-chain=2". Kindly help me to identify the issue and fix it.

Hi @Faizalsraman

Did you use 2 of 64X32 LED sign boards?  
If so, check the HUB74 cable connections once more.  
And if your LED uses 1/32 multiplexing , some jumper settings for Electrondragon HAT might be necessary.  
Pls see [LED-10. Make 256 X 126 size RGB Matrix](https://iot-for-maker.blogspot.com/2020/07/led-8-make-256-x-126-size-rgb-matrix.html).

No, I am using 32x32 LED sign boards. The overall resolution is 128x96 (4x3 matrix). And I am using Electrodragon HAT v2.
