Nope. Large eInk is unfortunately super niche and expensive. Dasung also has eInk products designed to be monitors but they are just as expensive as Boox's stuf

Nope. Large eInk is unfortunately super niche and expensive. Dasung also has eInk products designed to be monitors but they are just as expensive as Boox's stuff while doing less (but they are better as monitors). Since Boox's products are all just Android tablets you could try apps like SpaceDesk to use a cheaper 10" eInk tablet as a monitor which are a fair bit cheaper at ~$500.
