[Nutul]

You should post those images along with a description of the issue in the Waveshare Forum.

related your suggestion I've open a tiket support some an a tecnician is managing this case ... but is a hard situation  because also there is a jet lag that complicate moreover the comunication

however I take your suggestion seriously, in the forum other people may have already solved the problem

but if any person have suggestions to solve the problem i will thank

mmm, 270 and 90 are the same thing, just upside-down...
I'd try 180 as well, this will supposedly turn 90-deg ccwise, which is what you want.

I've try this too but not work...
in bootPhase do the scroll lines from rh to lh as is

in MoOde GUI instead the inerface is that

so... the display can actually be rotated in any of the four directions, and the text orientation proves it.
It looks like moode assumes it to be thin and tall, rather than thin and wide...
Or the framebuffer can be configured the correct way (using the orientation parameter), while the reported viewport never changes to 1280 x 400, and always remains at 400 x 1280, indicating vertical orientation only...

video=DSI-1:400x1280e,rotate=270 console [...]

maybe setting the above to video=DSI-1:1280x400e,rotate=270 changes anything? Just wandering wild here, but seeing you always report the viewport being 400x1280 I begin thinking it may be defined somewhere...

Let me know, looks an interesting task...
