Mapper Suggestion for 192x192 display

Hello dear users and friends of rpi-rgb-led-matrix.

Im building a 192x192 display and i wonder what mapper could work best to display my image correctly .

Using active adapter and a raspberry pi 4


Ive tried using u mapper and off course worked. But the fact of flipping the screens makes some lines in my final images due to the flipped LEDS . I need help on knowing what would be the parameters or if someone have done a square matrix using v mapper. Maybe the creator of V mapper @marcmerlin could give me a lead?

Thanks a lot

When you say flipped LEDs, do you mean something like this?


I ask because I too have encountered this and am not sure how to resolve it.
