If you think Amazon has ended up with a new hardware release for a year, think again: Alex Fire There is an updated version of the Amazon Fire TV Stick on the remote for the first time with volume, mute and power buttons. The new Fire TV Stick 4K supports Dolby Atmos audio as well as three major HDR standards: HDR10, HDR10 + and Dolby Vision.
Among them, Dolby Vision and HDR10 + are new products on the Fire TV Stick line. These two standards support dynamic metadata that provides more detail for the brightest and darkest parts of an image when viewing compatible content on compatible TVs. It's a subtle improvement, but if you tried to buy a compatible TV, it would be something to worry about.
Amazon was one of the most important cheerleaders of the HDR10 + standard. I have previously announced that all original content will release standard support. Dolby Vision content is provided by Netflix, Vudu, Rakuten and Amazon Prime Video.
