Performance for Single Colour displays?

Is this library already optimised for single colour displays and I can get 6 parallel chains single colour output using RGBRGB?
What is the expected resolution from one chain expected?
I’m looking to get 16x336 from one colour output. That’s a bit less than 128 x 3
So is this possible if I use single bit data for output?

Thanks

The library is designed for driving these panels with higher color depth, 24 bit color (8bit per channel) minimum.

I will only need 1 bit per channel, Is this possible easily?

Sorry, no it’s not possible currently.
