Interesting. But updating one character should be much faster than updating the whole screen then surely since you don't have to send so much data?

By the way I suspect compressing multiple pixels into one is unnecessary - just quantise them and let the compression deal with it.

Also zlib is not designed for image compression. I'm sure there is something more suitable, e.g. QOI.

In fact, given that you're mostly compressing mono text I wouldn't be surprised if some kind of dynamic sprite atlas kind of system was better, like in JBIG2.

Anyway if it is network latency that seems like good news because you should be able to get it to near 0. What is the ping to the reader?

Apologies for the late reply @IshKebab, I read into your recommendations and they are very interesting.

If you wish you could copy your comment verbatim as an issue over here, so we can discuss it further: https://github.com/everydayanchovies/eink-vnc/issues

I will have a chance to test the ping tonight, possibly.
