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.
TBF, if a potential partner is super excited about something you never heard of, looking into it is a good thing.
Conservatives, and other assholes, are good about hiding their crazy behind seemingly innocent things, like pepe the frog.
