I bought a 21 inch 1080p Viewsonic monitor from a thrift store just the other day for $6. I got it just for this use case.
I had a spare for this purpose up until about a month ago when the backlight went out on one of my daily drivers.
Also, a couple of days ago I got a pretty nice steelcase apex 3 keyboard with RGB lights for $5.
EDIT: And after making the comment below I just noticed the date on the version is 2022? I’m going need to try out the latest version from their Git.
I use droidify because I like the look of it better. It comes with another repo enabled by default called IzzyOnDroid which has the Alpha versions of lawnchair.
I’ve been using it for years. It’s great.
