Increase refresh speed - waveshare 6inch HD e-Paper HAT about papertty HOT 4 OPEN

Which RPi are you using? To get decent speeds with a display this size an RPi3b+ / RPi4 might be best. There's a lot of room for optimization in general, though.

I'm using a RPI 4.
I'm doing some code teaks, but with no noticeable improvements.

Hi, Do you got some tips. Help me go to the correct direction?

Cumps,

You can set the max_speed_hz (driver_it8951.py:183) to something higher. 18 MHz worked for me, but it stopped responding after running it for a few hours. Could be unrelated though. There was no permanent damage as far as I can tell. VNC uses the grayscale instead of black-and-white mode, which uses more data (I think it was a factor of four because even b/w uses 2 bits per pixel) and is therefore slower. You could add another filtering step to turn it into a black-and-white picture after papertty.py:369 to speed things up if you can accept the loss of quality.
