Product Snapshot


The Insignia Fire TV 4K is a budget-friendly option in the smart TV market. Introduced with Amazon Fire TV OS starting in 2021, it has built-in smart functionality and easy access to numerous streaming apps. Like many of the Best TVs available now, it has voice command and hands-free remote options.

The series includes various screen sizes from 43 to 75 inches. 43 to 55-inch versions have a maximum resolution of 4K at 60Hz. The Insignia4K Fire TV includes an ethernet port, VCA inputs, composite video inputs, digital optical audio output, a headphone jack, and a coaxial jack.

A gaming mode cuts input lag from the nominal 86 ms to around 35 ms. It has a 60 Hz refresh rate and supports variable refresh rates. With a lower price point, it caters to those seeking an affordable and convenient smart TV experience, particularly when paired with an Amazon Prime account.


our Verdict

The Insignia Fire TV 4K delivers 300 nits of brightness and 4660:1 native contrast but lacks color accuracy and wide viewing angles. It has 1 USB port, digital audio, cable jack, and 3 HDMI ports. You’ll notice reflections in bright light. The built-in Fire TV OS provides seamless streaming and Alexa voice control, though it has distortion at viewing angles past 29 degrees.

The remote is convenient, but compared to other 4K sets, its picture performance disappoints. Black levels are not very uniform, and there is noticeable blooming. The color gamut is not wide, so HDR is average, and its 300 nits of brightness sits at the lower end of the market, nevertheless, for budget-conscious consumers looking for a smart TV, the Insignia Fire TV 4K is worth considering.

ReasonS to Buy

  • Good native contrast for its price point
    • The 4660:1 native contrast means blacks should be deep and bright areas suitable bright, adding sharpness. 

  • Convenient user interface
    • The built-in Fire TV OS provides seamless streaming and Alexa voice control, making it a useful smart home device hub.

Reason to Avoid

  • Disappointing picture quality
      • The Insignia Fire TV 4K delivers a below-average 300 nits of peak brightness 
      • Inaccurate black uniformity in dark rooms
  • Narrow viewing angles
    • Colors appear washed out at angles beyond 30 degrees, limiting seating options and making it difficult to set up in wider rooms.

  • Slower response time than some competitors
    • The tested 35-85 ms response time is slower than many other 4K TVs. The best TVs for gaming offer game modes with 15ms or less response times.
