Picture Quality

The 4-Series utilizes an LED panel with basic HDR (High Dynamic Range) support. While it delivers a noticeable step up from Full HD in terms of sharpness and detail, it falls short of the picture quality offered by pricier competitors. Here’s a breakdown of its key aspects:

  • Resolution and Sharpness: The 4K resolution delivers crisper details and clearer text compared to Full HD. Upscaling of lower-resolution content is decent, making even older shows look somewhat improved.
  • Color Accuracy: Colors appear acceptable for casual viewing, but videophiles might find them less vibrant or accurate compared to higher-end TVs. Calibration options are limited, making fine-tuning the picture challenging.
  • HDR Performance: The 4-Series supports HDR10 and HLG, but the limitations of the panel become apparent. Peak brightness isn’t sufficient to deliver the full impact of HDR content, resulting in a somewhat washed-out appearance in highlights. Additionally, the lack of local dimming results in blooming (halo effect) around bright objects in dark scenes.

Overall, the picture quality of the 4-Series is suitable for casual viewers who prioritize affordability. However, discerning viewers or those seeking a more immersive HDR experience might be better served by looking elsewhere.


Amazon Fire TV 4-Series 4K UHD smart TV design

The 4-Series embraces a minimalist design with thin bezels and a basic plastic back panel. While not the most luxurious looking TV, it maintains a clean aesthetic that blends well with most living spaces. The included stand provides decent stability, but some users might find it a bit wobbly.

How Does it Compare? Stacking Up Against the Competition

The 4-Series faces stiff competition in the budget 4K TV market. Here’s a quick comparison against two key rivals:

  • TCL 4-Series (S434): The TCL 4-Series offers a similar price point and boasts a VA panel with potentially deeper blacks. However, viewing angles might be narrower on the TCL, and the smart platform can feel less intuitive compared to Fire TV.
  • Insignia F50 Series: The Insignia F50 Series is another budget contender with a similar feature set. It might offer slightly better contrast, but the motion handling on the Insignia can be choppier than the 4-Series.

Ultimately, the best choice depends on your priorities. If deeper blacks are essential, the TCL might be a better fit. If a user-friendly smart platform is a must-have, the 4-Series remains a strong contender.

Brightness and Contrast

The 4-Series offers decent brightness, making it suitable for most living room settings. However, it might struggle in very bright rooms where glare can be an issue. The contrast is a point to consider. The lack of local dimming technology limits the panel’s ability to produce deep blacks, resulting in a somewhat washed-out look in dark scenes. This can be particularly noticeable when watching movies or shows with a lot of dark content.

Sound Quality

The built-in speakers on the 4-Series are adequate for casual viewing but lack the depth and power needed for a truly immersive experience. Dialogue is clear, but bass is lacking, and the overall audio can feel thin for action movies or music.

To elevate your viewing experience, investing in a soundbar or a surround sound system is highly recommended. This will provide a more robust and immersive soundscape, especially for movie nights and big sporting events.

Smart Features

The Fire TV platform stands out for its user-friendliness. Even non-tech-savvy viewers will appreciate the clean and intuitive interface that makes navigating menus and finding content a breeze. This is further enhanced by a vast library of popular streaming apps like Netflix, Hulu, Disney+, and YouTube, all readily available from the home screen. Fire TV also boasts Alexa voice integration, allowing you to control your TV and compatible smart home devices hands-free with simple voice commands. Search for content, adjust settings, or launch apps – all without reaching for the remote.

However, customization options are more limited compared to some competitor smart platforms. While Fire TV offers a good selection of apps and features, power users who heavily personalize their TV experience might find it somewhat restrictive.


The 4-Series utilizes basic motion processing technology to reduce blur in fast-paced scenes. This might be sufficient for casual viewers who primarily watch movies or shows with slower panning shots. However, judder (a stuttery effect) might be noticeable in rapid movements, particularly in action movies or sports. Hardcore gamers seeking the absolute smoothest motion for competitive gaming or fast-paced movies might want to consider a TV with a higher native refresh rate (like 120Hz) or more advanced motion processing. These higher-end features can significantly enhance the responsiveness and fluidity of fast-paced content.

Gaming Features

The 4-Series offers basic gaming features like Auto Low Latency Mode (ALLM) that reduces input lag for a more responsive gaming experience. This can be a plus for casual gamers who want to minimize the delay between their controller input and what appears on the screen. However, features like HDMI 2.1 with high refresh rates (VRR) are absent. These cutting-edge features are becoming increasingly important for serious gamers who want the most responsive and visually immersive gaming experience possible.

Durability and Build Quality

The 4-Series prioritizes functionality over luxurious materials. It utilizes a plastic back panel and a basic stand. While not the most glamorous design, the construction feels well-built and should last for years with proper care. Budget-conscious viewers who prioritize functionality over aesthetics will likely find this approach acceptable.

Viewing Angles and Screen Uniformity

The 4-Series offers decent viewing angles thanks to the LED panel technology. This makes it suitable for rooms with multiple viewers seated at different angles. Everyone can enjoy a clear picture without significant color or brightness shifts, even when not positioned directly in front of the TV. However, some users report issues with dirty screen effect (DSE), which can be more noticeable on larger screens. This can manifest as blotchy patches, especially in dark scenes. It’s important to note that DSE variance can exist from panel to panel, so some users might experience more or less of this effect than others.

The 4-Series offers a good selection of inputs, including 3x HDMI ports (one with eARC for connecting a soundbar), 1x USB port for media playback or connecting external devices, a digital optical audio output, and an ethernet port for wired internet connection. This selection caters to most viewers’ needs. You can connect various devices like streaming sticks, gaming consoles, Blu-ray players, and external hard drives without any limitations.

Overall Value

The Amazon Fire TV 4-Series strikes a balance between affordability and functionality. Here’s a quick recap:

  • Strengths: Affordable price point, user-friendly Fire TV platform with Alexa voice control, decent viewing angles, and enough connectivity options for most users.
  • Considerations: Limited picture quality compared to higher-end TVs, average motion handling, basic gaming features, and potential for DSE issues.


The Amazon Fire TV 4-Series emerges as a compelling choice for budget-conscious viewers seeking a feature-rich smart TV. Fire TV’s user-friendly interface and Alexa voice control make navigating content and controlling your smart home effortless. The 4-Series delivers decent picture quality and viewing angles, ideal for everyday entertainment. With a good selection of connection options, you can connect all your favorite devices for a truly versatile viewing experience. So, if you’re a casual viewer prioritizing a user-friendly smart platform and a good picture at an affordable price, the Amazon Fire TV 4-Series is a strong contender for your living room.
