Can you plug anything into a monitor?
Not really. You would need something to drive it.
You asked for dumb...
But for under 150 bucks you can have a raspberry pi gen 5 media box driving it that you can plug all the things into. Shit we drive our samsung tv with the pi 3b for a long time. Now it runs on a 4, repurposed the 3b to be an octoprint box.
$150 for a dongle seems a bit steep
A Raspberry Pi. Is not a dongle. It's a full fledged computer. On a single board, really small, easy to run and use. Designed originally as a cheap way to teach coding, it exploded massively. Now people have them doing all sorts of shit you don't need a whole real computer to run.
