P10 Hub75 first four lines are off #973

Hi there,

I am using a P10 Hub 75 board. With --led-multiplex=3 option I get a kind of right result. With every other multiplex the result is a mess.

I tried with demo 3 and as you can see, it looks like the first four rows should be flipped and be on the bottom.

Any one else got this behavior or got any tips for solutions?

Used command : ./demo -D3 --led-rows=16 --led-cols=32 --led-brightness=10 --led-multiplexing=3

Here is the x|y coordinate map, which I created. looks like it's internally a chained 16*16 panel and every third row is a copied one.

Anyone got an idea?

I figured I had to use the options --led-row-addr-type=1 --led-multiplexing=7, which almost gives me a good result. But I am missing one row.

Any suggestions?
