Amazon has launched new versions of its Fire TV sets, with a focus on practicality rather than fancy features. The 4K-capable Fire TV Omni QLED line now offers smaller models in 43-, 50- and 55-inch sizes, starting at a lower price of $450. These sets feature up to 96-zone local dimming, HDR using Dolby Vision IQ and HDR10+ Adaptive, as well as far-field microphones for Alexa control. The Ambient Experience has also been upgraded with “dynamic” art pieces that respond to time and weather, but this will not be available until later in the year.
