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.

And the RTO demands are about intentionally lowering headcount without paying unemployment or severance so they can boost their numbers.
