I use an older firestick on a 720p TV I keep in my basement and it works great with channels dvr.. often on sale for 25 bucks
the newer one has a remote that will control your TV, also able to power it off a USB port, so its completely wireless
I dont like the fire TV interface that much but the device does work. my main box is a shield.
avoid the generic android TV boxes, flakey and not well supported
