Really only interested in something like Graphene, Lineage, or a Linux mobile tablet that can work with a typical Linux distro and display over USB-C. It is just a casual conversational ask. Maybe one of y’all has tried or knows the answer. I won’t use anything that runs google stuff or is a pain to load a custom ROM.
Are you talking display out or display in?
Display out? https://www.hp.com/us-en/shop/pdp/hp-tablet-11-be0097nr
This thing actually runs windows and is x86 so you can run a Linux distro in theory.
Display in, I will edit this post but that’s not as common
Display-in is the app of interest
The max-boox-pro series had a HDMI-input to have an external eINK-screen and doubled as android laptop. Quite expensive though, and not that useful.
