Question: what is the difference between amazon firestick and firestick 4k?
Answer: The basic Fire TV Stick can stream content up to HD quality (1080p), but the Fire TV Stick 4K – as the name suggests – can reach 4K UHD resolution, around four times the number of pixels. The Fire TV Cube also supports 4K streaming. To stream in 4K, it's worth remembering that you'll need a 4K-capable television.
