TV prices are subject to constant fluctuations, especially as new models arrive and older units go on clearance. The Amazon 43-inch 4-Series 4K Fire TV is discounted to $270 from its $330 list price. If you've been shopping around for an inexpensive smart TV for a bedroom and you're looking for solid picture quality and smart features, this is definitely a set worth considering. Scoring a 4.4 out of five stars on Amazon (based on over 220 reviews), the Amazon 4-Series is generally praised by users for its picture quality and simple setup. Colors and contrast are decent for an entry-level 4K TV, and the 4-Series supports both HDR10 and HDR10+.
