I have RGB Matric panel with connections
as
P1–> P6–>P2–>P5–>P3–>P4
and below is its actual matrix placements
P1 P2 P3
Wwhich mapper i can use to be able to use these matrix as one display
Welcome to the forum!
Not sure whether this might be useful, I initially thought it could use a U-mapper but then this suggests you might get a better experience with a Z-mapper, if in doubt maybe (and apologies in advance…) Caude (etc) might be able to advise on the specific use case, and if something doesn’t already exist might generate a mapper you can plug into the library for your exact layout.

Is there a U-Mapper that doesn't require the tile be flipped upside down?
I … just got my P10 outdoor tile working, but its a louvered tri-LED tile that you cant really flip around without it looking like poo.
So, I am trying to build a 6 long string which is 3 tiles on top, 3 tiles on bottom. So basically, a U-Mapper.
But it flips the bottom.
Thoughts?
Please check out the documentation:
Remapping coordinates (pixels within panels and assigning pixel order across panels)
------------------------------------------------------------------------------------
Some panels do not even output pixels in the natural left to right, up to down order.
For those, see multipler lower down on this page.
For now, let's focus on how panels are chained.
You might choose a different physical layout than the wiring provides.
The library by default will do this the horizontal way
```
chain 1 - P1 - P2 - P3
chain 2 - P1 - P2 - P3
chain 3 - P1 - P2 - P3
```
Once you go past 4 or 5 panels wide, you may want to have a layout like this.
For that, you want U-mapper.
```
chain 1 - P1 - P2 - P3
P6 - P5 - P4
chain 2 - P1 - P2 - P3
