What's the cheapest hardware that can playback videos at 1080p?

There are so many options out there, it's kind of dizzying.

I'm looking for a cheap solution that I could hook up to a TV and ethernet, so it could run a flavor of Linux (or BSD) and play videos at 1080p. Bonus points if it can handle 1080p@60 FPS. Other than that, it would be used for light web browsing.

I was looking at Raspberry Pi 4, but is there anything else you would suggest?
