Hi,
I'm experimenting with RGBToHDMI (https://github.com/hoglet67/RGBtoHDMI i'm using the latest stable release 20221221_156e2f0 Release )
It works superbly on a pi zero, but have some strange effect on my pi3A+ with exactly the same SD card.
I have only one pi zero, and a lot of pi 3A+, so it would be great if i can get it to work nicely.
Here's some screen captures I took :

On the pi zero, all is fine and nice :
Zero with maniac mansion :

Zero at the boot menu :

On the PI3A+, exactly same setup, same SD card,i get cyan stripes.

PI3A+ at the boot menu

Here is a zoom in on the problem :

I hope i could just change some setting and make it work on pi3a+ as well.

Is there anyone running RGBToHDMI who has an idea what this could be,
or could try it as well with a pi3a+, and tell me if he has the same effect or not ?

If I find a solution myself, i will also post in this thread so it could help other pi3a+ users.. 😀
