2. Post a picture of the problem and describe what you expect to see
I runned pixeltime example, but I just get this image to see. I am trying to run this panel put no matter which
MuxPattern and ScanPattern I choose.
Run the pattern test and post the result as gif/video (need to have a bit more than one full RED/YELLOW/WHITE cycle)
The pattern test looks like this, when I start it.
The chip which is on the back side of the boad is called MBI5124GP, maybe this helps.
Found nothing to it on the internet so I hope I can get a solution here.

2. Post a picture of the problem and describe what you expect to see
I runned pixeltime example, but I just get this image to see. I am trying to run this panel put no matter which
MuxPattern and ScanPattern I choose.
The pattern test looks like this, when I start it.
I'm using version 1.8.2 of PxMatrix and try to use it with an ESP32 Dev Module.

The chip which is on the back side of the boad is called MBI5124GP, maybe this helps.
Found nothing to it on the internet so I hope I can get a solution here.
