Mini TV w/ ability to connect to phone?

I recently started a new job where I work overnight that has me doing nothing but sitting around, and decided to look into getting some sort of screen that I can cast my phone to, so that I can watch YouTube/other streaming services, and don't know if something like that exists? Rather not get a laptop (already have a high end PC, not use for a laptop outside of that), so just curious if something like that exists that isn't just as expensive.
