You configured port 2/3. Those ports use the same GPOIs used by the USB serial device. You are looking at the pixel data going out.

I had the suspect but did not believe such design decision :-( , and could not find any schematic of the board, just a pinout that does not mention the serial port pins https://quinled.info/quinled-dig-octa-brainboard-32-8l-pinout-guide/

That was a Quindor decision. Nothing I could do about it.
