Amazon Fire TV 50" 4-Series $319.99 at Amazon $399.99 Save $80.00 Get Deal Get Deal $319.99 at Amazon $399.99 Save $80.00 If youre looking for a basic 4K TV for under $350, this one might check your boxesnote, however, the emphasis on basic. It supports HDR10 and HLG, but skips Dolby Vision, which affects how well it handles color and contrast in HDR content. This might be a dealbreaker if youre picky about picture quality. This TV also lacks the newer ATSC 3.0 tuner, so you're limited on over-the-air 4K broadcast options. The Fire TV interface is smooth enough, especially if youre already in the Amazon ecosystem, and it offers built-in access to Netflix, Disney+, Hulu, and more. You also get Apple AirPlay, which makes it easier to mirror or stream from Apple devices.That said, its not built for high-performance viewing. The panel isnt the brightest, and in dark rooms, the contrast can feel flat. Motion handling is serviceable for regular TV and movies, but if youre hoping to watch fast-paced sports or play video games, youll notice some lag and blur. The Alexa voice remote works well, though its not hands-free like some higher-end Fire TVs, notes this PCMag review. Still, setup is quick, the build doesnt feel cheap, and itll handle casual use just fine. This deal makes sense for a backup TV, a dorm room, or anyone replacing an older screen on a tight budget. But if youre chasing deep blacks, punchy highlights, or silky-smooth frame rates, youll want to shop higher up the food chain.Shopping for tech? Lifehacker can help you make the right decision.
