2x2 panels of 64x32px

Is there a way to make this configuration work as 128x64,
or in the worst case, is there some trick to make it work as 256x32?

My current setup is two 64 x 32 running in a 128 x 32 on an Intersate 75 Pico W onboard .
Is that a typo or do you really want 128 x 64 ?

@alphanumeric007 thanks, not a typo, i have 4 64x32 panels and i want to chain them in a 2x2 matrix.
Currently I ended up having two controllers one for each row, obviously not ideal.

Ah OK, I missed the 2x2 part. At one time I wanted to run mine as 64 x 64 and din't have much luck library code wise. I have mine physically vertical one panel on top of the other. I just compensate with placement x, y in my code. I'm just displaying text so it's doable for me.
I'll tag along though and see what other might post.

Looking back over i75 and thinking how we might approach this, I'm wondering how well a pure MicroPython display driver might perform since trying to cram all the types and permutations of panel into the existing, quite rigid C driver is quite complicated. We originally built the library to support the display we stocked/sold (and thus had access to testing).

The other half of the problem is the diminishing returns of running higher resolution setups while maintaining 10-bit depth (for maintaining full dynamic range when gamma-correcting from 8-bit) and a decent framerate.

Behind the scenes we're working on a dual channel, RP2350-based driver to make a really nice 128x128 kit, including a whole new graphics library. Hopefully some of this work will make it easier to support other panel configs.
