So I'm sitting here on my computer—something I do quite often—and find
myself staring at this Lilliput 7” USB display that I have here. I've had this
thing for a while; I bought it to use for Slack at work originally, and it
worked OK. 7” turns out to be just slightly too small for anything serious, but
it worked alright for chat at least.
Anyway, I brought it home and hooked it up to my Windows PC and never found
anything really great to use it for. Suddenly I had a brainstorm: what if it
could work on a Raspberry Pi? Then I could put some useful home automation
output on it and maybe position it somewhere else in the house.
I set about figuring out how to get the Raspberry Pi to send GUI output to this
USB-powered DisplayLink monitor. I did, eventually, get it to work. But, I ran
across so many conflicting, incorrect, and outdated articles that I am compelled
to describe what I did to make it work.
