SPI display speed increase

[JuMalIO]

Is there a way to increase speed of filling a screen one color even more?
Is it possible to reduce color depth or something like that?
Or to have "update" function like in SSD1306?
Or there is no way around this and I need to get nextion display?

Hi, I didn't try this and I'm not the developer, but you can maybe try to use DMA instead of polling when sending the data, and thus speed up the process, since you can fill buffers while data is being transmitted
