There are several options for those looking to buy a TV with Amazon's Fire TV platform built in. None of those options offers local dimming — until now. Toshiba's new M-Series line of Fire TVs offers up to 48 local dimming zones in sizes ranging from 55" to 75". Other notable visual upgrades include a native 120Hz panel, an automatic low-latency mode, and support for both Dolby Vision and HDR 10. Audio features include support for both Dolby Atmos and DTS Virtual:X, although as with nearly all modern displays, you'll want a separate soundbar or audio system for best results.
