difference between a fire stick and fire tv
If you have a 4K TV, the Fire TV box will help you get the most out of it. This device supports a variety of apps in full UHD resolution, including heavy hitters like Amazon Video, Netflix and YouTube. The Fire TV Stick, on the other hand, caps out at a full HD resolution of 1080p. While the Fire TV box will work with full HD machines, and the Fire TV Stick will work with UHD machines, you should probably get the one that's optimized for your TV's display.
