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.
What you could do is get a USB c capture card and use something like vlc. Latency would be there but itd work.
