The Amazon Fire TV 4-Series is a very basic, entry-level 4k TV. Along with the Fire TV Omni, it's one of the first Amazon-branded TVs. It's best-suited for a dark room, as the VA panel delivers deep blacks but can't get bright enough to overcome glare in a bright room. It has fantastic low input lag for gaming, but it doesn't support any advanced gaming features. The Fire TV smart interface is easy to use, and it has a great selection of additional apps, so you're sure to find your favorite streaming service. Unfortunately, it's not a very good TV overall, with poor viewing angles, mediocre gradient handling, and a slow response time. It has terrible accuracy out-of-the-box, and it doesn't support any calibration at all, so there's no way to correct the issues.

Our Verdict

6.5 Mixed Usage

The Amazon Fire TV 4-Series is an okay TV overall. It's best suited for a dark room, as visibility can be an issue in brighter rooms. It's passable for watching movies or TV shows, with a great selection of streaming apps. It's not very good for watching sports or playing video games, though, as it has a slow response time, and HDR adds very little, as it's not bright enough for small highlights to stand out, and it can't display a wide color gamut.

Pros
  • Excellent contrast.
  • Great selection of streaming apps.
  • Decent reflection handling.
Cons
  • Image degrades at an angle.
  • Slow response time.
  • Not bright enough to overcome glare.
  • Terrible accuracy and no calibration settings.
6.4 Movies

The Amazon Fire TV 4-Series is a passable choice for watching movies in a dark room. It has excellent contrast and reasonable black uniformity, so it looks good in a dark room, but sadly, there's no local dimming feature to improve black levels. It displays 1080p and 4k content well, but older DVDs aren't upscaled as well as other TVs. It can remove judder from all sources, and there's very little stutter.

Pros
  • Excellent contrast.
  • Great selection of streaming apps.
  • Judder-free from any source.
Cons
  • No local dimming.
  • Terrible accuracy and no calibration settings.
6.9 TV Shows

The Amazon Fire TV 4-Series is an alright TV for watching shows in a bright room. It upscales 1080p content well, and the smart interface has a great selection of streaming apps, so you're sure to find your favorite shows. Sadly, although it has decent reflection handling, it has just okay peak brightness, so visibility is an issue in brighter rooms. It also has poor viewing angles, so it's not a good choice for a wide seating arrangement or if you like to move around with the TV on.

Pros
  • Excellent contrast.
  • Great selection of streaming apps.
  • Decent reflection handling.
Cons
  • Image degrades at an angle.
  • Not bright enough to overcome glare.
  • Terrible accuracy and no calibration settings.
6.6 Sports

The Amazon Fire TV 4-Series isn't a very good TV for watching sports in a bright room. It has a relatively slow response time, resulting in significant blur around fast-moving objects. It has fair gray uniformity, but there's significant dirty screen effect, which can be distracting when watching sports. Although it has okay peak brightness and decent reflection handling, visibility is an issue in brighter rooms. It's also not great for a wide seating arrangement, as the image degrades when viewed at an angle.

Pros
  • Excellent contrast.
  • Great selection of streaming apps.
  • Decent reflection handling.
Cons
  • Image degrades at an angle.
  • Slow response time.
  • Not bright enough to overcome glare.
  • Terrible accuracy and no calibration settings.
6.6 Video Games

The Amazon Fire TV 4-Series is an okay TV for playing video games. It has fantastic low input lag, resulting in a responsive gaming experience, but it doesn't support any advanced gaming features like FreeSync, and it doesn't have any high-bandwidth HDMI 2.1 ports. It also has a slow response time, so there's noticeable blur behind fast-moving objects.

Pros
  • Fantastic low input lag.
  • Excellent contrast.
Cons
  • Slow response time.
  • No advanced gaming features.
  • Terrible accuracy and no calibration settings.
6.1 HDR Movies

The Amazon Fire TV 4-Series is just passable for watching movies in HDR. It has excellent contrast and reasonable black uniformity but no local dimming feature to improve contrast. It can't get very bright in HDR, so small highlights don't stand out at all, and it can't display a wide color gamut. It can remove judder from all sources, though, and there's very little stutter.

Pros
  • Excellent contrast.
  • Great selection of streaming apps.
  • Judder-free from any source.
Cons
  • No local dimming.
  • Can't display a wide color gamut.
  • Terrible accuracy and no calibration settings.
6.7 HDR Gaming

The Amazon Fire TV 4-Series is just okay for gaming in HDR. It has fantastic low input lag, resulting in a responsive gaming experience, and it has excellent contrast, resulting in deep blacks in a dark room. Sadly, there's no local dimming feature to improve contrast, it can't get very bright in HDR, and it can't display a wide color gamut. It doesn't support any advanced gaming features like variable refresh rates, and it doesn't have any high-bandwidth HDMI 2.1 ports.

Pros
  • Fantastic low input lag.
  • Excellent contrast.
Cons
  • No local dimming.
  • Slow response time.
  • No advanced gaming features.
  • Can't display a wide color gamut.
  • Terrible accuracy and no calibration settings.
6.4 PC Monitor

The Amazon Fire TV 4-Series is a mediocre TV for use as a PC monitor. It has fantastic low input lag in 'Game' Mode but narrow viewing angles, so the sides of the screen don't appear uniform if you're sitting too close to the screen. Sadly, it can't display chroma 4:4:4 properly with any resolution, so text doesn't look good, and it has a slow response time, so there's noticeable blur behind fast-moving objects.

Pros
  • Fantastic low input lag.
  • Excellent contrast.
  • Decent reflection handling.
Cons
  • Can't display 4:4:4 chroma properly.
  • Image degrades at an angle.
  • Slow response time.
  • Terrible accuracy and no calibration settings.

The Amazon Fire TV 4-Series is Amazon's first branded TV, sitting alongside the Amazon Fire TV Omni Series. It's a very basic, entry-level 4k TV, similar to other budget models, like the Toshiba C350 Fire TV 2021 or the Hisense A6G.

The Amazon Fire TV 4-Series has a basic design, with a glossy black finish. It doesn't look as nice or as premium as the Toshiba C350 Fire TV 2021.

Design
Stand

The stand is pretty basic, but it supports the TV well, with just a bit of wobble. The feet are wide-set, but leave enough room to place most soundbars in front of it.

Unfortunately, there's no cable management on the back of the TV. The inputs are all housed in the center of the TV, so they're difficult to access when the TV is wall-mounted.

Build Quality

Sadly, the Amazon Fire TV 4-Series has mediocre build quality. It looks and feels cheap, and there's a bit of flex and a creaking noise coming from the back panel. The feet and bezels of the TV are glossy black plastic, which looks cheap. Overall, it doesn't feel very solid.

The Amazon Fire TV 4-Series has an excellent contrast ratio, so blacks look black in a dark room instead of gray. Unfortunately, there's no local dimming feature to improve contrast. Contrast can vary between individual units, but these results are about what we expect from a VA panel.

Note: The contrast photo taken here appears cooler than most of our other TV reviews. That's because this TV has a very cool color temperature, and it can't be calibrated, so we're unable to correct this.

The Amazon Fire TV 4-Series has just okay peak brightness in SDR. There's very little variation in brightness with different content, which is great. Very small scenes are dimmed a tiny bit, but this is far from noticeable.

We tested the SDR peak brightness with the most accurate settings out-of-the-box, in the 'Movie' Picture Mode with the Backlight at its max, Contrast at '50', Gamma at '0', Color Saturation at '45' and the Color Temperature set to 'Warm'. Normally we measure peak brightness after calibration, but this TV doesn't have any calibration settings. The peak brightness varies a bit with the other picture modes, but this is about as bright as the TV can get.

Sadly, the Amazon Fire TV 4-Series has poor peak brightness in HDR. Small highlights aren't bright enough to stand out at all. It follows the EOTF well, but there's a sharp roll-off near the TV's peak brightness, causing a loss of fine details in bright scenes, and blacks are raised a bit in near-dark scenes.

We measured the HDR peak brightness in the 'Movie' Picture Mode with the Backlight at its max, Contrast at '50', and the Color Temperature set to 'Warm'. Setting the Color Temperature to 'Standard' instead results in a slightly brighter image overall, as shown in this EOTF, but the overall peak brightness is still about the same.

There's no noticeable difference in peak brightness in 'Game' Mode, but it doesn't track the EOTF quite as well, as most scenes are over-brightened a bit. This isn't really noticeable, and most games allow you to adjust this anyway, so it's not a big deal. Sadly, it's still way too dim for an impactful HDR gaming experience.

The Amazon Fire TV 4-Series has fair gray uniformity. There's quite a bit of dirty screen effect on our unit, which can be distracting when watching sports, and the sides of the screen are significantly darker than the center.

Unfortunately, the Amazon Fire TV 4-Series has terrible accuracy out-of-the-box, even with the most accurate settings.

Gamma is pretty close to our target of 2.2 for a dark room, though, but bright scenes are over-brightened a bit. The accuracy out-of-the-box can vary between individual units, but we don't expect other units of this model to look much better than this.

Update 12/20/2021: Amazon has added basic calibration support for this TV. We'll retest it shortly and update the review.

Sadly, when we originally tested the Amazon Fire TV 4-Series, it didn't offer any calibration support at all. The settings used to calibrate the Toshiba Fire TV 2020, which uses a nearly identical smart platform, simply don't exist on this TV. Because of this, our out of the box settings are also the most accurate, and there's no way to correct for the terrible accuracy of this TV.

You can see our recommended settings here.

480p Input

The Amazon Fire TV 4-Series does a decent job upscaling 480p content, like DVDs. There's a slight issue with 480p content, though, as the image is cut slightly and then stretched to fill the screen. It's not as bad as the TCL 6 Series/R646 2021 QLED, but still a bit worse than most other TVs. We tried adjusting all of the TV's upscaling settings, but we couldn't get it to stop doing this.

Note: The upscaling photos taken here appear cooler than most of our other TV reviews. That's because this TV has a very cool color temperature, and it can't be calibrated, so we're unable to correct this.

It doesn't cause any issues for video content, but if you plan to use this TV as a PC monitor, it might be an issue for text clarity. You can read more about this here.

Update 12/20/2021: We retested audio passthrough, and found that Dolby Atmos via TrueHD vie eARC works.

The Amazon Fire TV 4-Series supports eARC, and it supports passthrough of some advanced audio formats when your TV is connected to a high definition video source.

Unfortunately, this TV has a disappointing frequency response. The low-frequency extension (LFE) is extremely high, resulting in a very weak bass, with no thump or rumble at all. Above the LFE, the frequency response is fairly balanced, so dialogue sounds clear, as long you're not at max volume, as there's a bit more compression.

This TV has okay distortion handling. There's not much distortion at moderate listening levels, but it's a bit more noticeable at max volume. Not everyone will hear this, though, and it varies depending on the content.

The Amazon Fire TV 4-Series runs a slightly more recent Fire TV interface than the previous non-Amazon branded Fire TVs, including the Toshiba C350 Fire TV 2021. The interface is smooth and easy to use, and we didn't notice any bugs during testing.

The remote is nearly identical to the one included with the Toshiba C350 Fire TV 2021. It's a pretty basic remote, but it has built-in voice control, which you can use to change inputs, launch apps, or search for content, but it can't adjust the TV's settings. Through Amazon Alexa, you can use the voice controls to control other compatible smart products.

Note: Our unit was purchased in Canada, as we weren't able to get one quickly enough from the U.S. The quick access buttons at the bottom of the remote are slightly different on U.S. models.

Differences Between Sizes And Variants

We tested the 55 inch Amazon Fire TV 4-Series, and we also expect our results to be valid for the 43 inch and 50 inch models.

Size SKU number (U.S.) SKU number (Canada)
43" 4K43N400A 4K43N400C
50" 4K50N400A 4K50N400C
55" 4K55N400A 4K55N400C

If someone comes across a different type of panel or if their Amazon Fire TV 4-Series doesn't correspond to our review, let us know and we'll update the review. Note that some tests, like gray uniformity, may vary between units.

You can see the label for our unit here.

Compared To Other TVs

The Amazon Fire TV is a very basic entry-level TV, and it's outperformed by the vast majority of TVs on the market. There are much better choices available in the same price range from other budget brands, including Hisense and TCL.

Also see our recommendations for the best budget TVs, the best smart TVs, and the best small TVs.

LG C1 OLED
48" 55" 65" 77" 83"

The LG C1 OLED and the Amazon Fire TV 4-Series are very different TVs, with different panel types, but the LG is significantly better in every way. The LG is brighter, it's more accurate, it has much better dark room performance, and it has better reflection handling. The LG has better motion handling, more gaming features, and it supports HDMI 2.1.

Sony X90J
50" 55" 65" 75"

The Sony X90J is much better than the Amazon Fire TV 4-Series. The Sony has a great full array local dimming system, so it's a better choice for a dark room. The Sony also gets significantly brighter, it has a faster response time, and it has much better accuracy.

Sony X85J
43" 50" 55" 65" 75" 85"

The Sony X85J is significantly better than the Amazon Fire TV 4-Series in every way. The Sony has much better accuracy, it's significantly brighter, and it has better black uniformity. The Sony also has better contrast, a much faster response time, and better uniformity.

Hisense U6G
50" 55" 65" 75"

The Hisense U6G is much better than the Amazon Fire TV 4-Series. The Hisense has a full array local dimming feature, better black uniformity, and it's much brighter. The Hisense also has much better accuracy, even after calibration, as the Amazon can't be calibrated. Finally, the Hisense has a faster response time, and the unit we bought has better gray uniformity.

Amazon Fire TV Omni Series
43" 50" 55" 65" 75"

The Amazon Fire TV Omni Series is better than the Amazon Fire TV 4-Series. The Omni has better accuracy out of the box (but still no full calibration system), and it's a bit brighter. The Omni also has a slightly faster response time, and the unit we bought has better black uniformity. Finally, the 65" and 75" models of the Omni have a more premium design, with hands-free voice control, and those sizes support Dolby Vision.

Hisense A6G
43" 50" 55" 58" 60" 65" 70" 75" 85"

The Hisense A6G and the Amazon Fire TV 4-Series use different panel types, each with strengths and weaknesses. The Amazon TV is better for a darker environment, as it has better contrast and better black uniformity. The Hisense has much better viewing angles and much better accuracy, but it's better suited for a room with a bit of lighting, as it has low contrast but can't get bright enough to overcome glare.

TCL 4 Series/S446 2021
43" 50" 55" 65" 75" 85"

The Amazon Fire TV 4-Series and the TCL 4 Series/S446 2021 are basic entry-level TVs, and the models we tested have different panel types with strengths and weaknesses. The Amazon TV has a VA panel, which has a higher contrast, while the TCL we tested has an IPS-like panel with wider viewing angles, but there are variants of the TCL with a VA panel instead. The TCL has much better accuracy out-of-the-box, and you can calibrate it if the colors are inaccurate, which you can't do with the Amazon TV. The TCL also upscales 480p content better because it doesn't crop the image, and it displays 4k content without issues. Both TVs remove 24p judder from native sources and apps, but the Amazon TV also removes it from 60p/i sources, which is great.

Toshiba C350 Fire TV 2021
43" 50" 55" 65" 75"

The Amazon Fire TV 4-Series and the Toshiba C350 Fire TV 2021 use different panel technologies, each with strengths and weaknesses. The Amazon TV has much better contrast, so it's a better choice for a dark room. The Toshiba TV has wide viewing angles, but it's not a good choice for a bright room, as it can't overcome glare.

Hisense R6090G
43" 50" 55" 65"

The Hisense R6090G is much better than the Amazon Fire TV 4-Series. The Hisense has much better accuracy, even out-of-the-box, and it has better black uniformity. The Amazon TV is a bit brighter, and it can remove judder from more sources. The Hisense is also better for use as a PC monitor, as it can display chroma 4:4:4 properly.
