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 even calibrating it doesn't fix many issues with the accuracy, so the image looks off.
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.
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.
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.
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.
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.
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.
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.
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.
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.

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.
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.
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. 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.
The Amazon Fire TV Omni Series is better than the Amazon Fire TV 4-Series. The Omni has better accuracy out of the box, 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.
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.
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. Finally, the Hisense has a faster response time, and the unit we bought has better gray uniformity.
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.
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.
The Insignia F50 QLED is better than the Amazon Fire TV 4-Series. The Insignia has much better accuracy out of the box, a faster response time, better uniformity, and it's a bit brighter. On the other hand, the Amazon TV can remove judder from all sources, and it's better at upscaling low-resolution content like DVDs.
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.
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.
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.
Footprint of the 55 inch TV: 39.2" W x 11.8"" D x 2.51" H
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.
The borders are thicker than most TVs on the market, but they're not too distracting.
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. Also, the photo above looks blueish because the TV has a cold color temperature, even after calibration.
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.
These measurements are 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'. When we first tested the TV, it didn't have any calibration settings, but it has 1-point white balance calibration settings with firmware version 220.127.116.11 and higher. After calibrating the TV, it has similar brightness as before, so calibration doesn't affect the peak brightness.
The Amazon Fire TV 4-Series doesn't have a local dimming feature. We still film these videos on the TV, though, so you can see how the backlight performs and compare it with a TV that has local dimming.
This TV doesn't have a local dimming feature. We still film these videos on the TV, though, so you can see how the backlight performs and compare it with a TV that has local dimming.
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. Uniformity can vary between individual units. Near-dark scenes have much better uniformity, but there are still some noticeable issues.
The Amazon Fire TV 4-Series we bought has reasonable black uniformity, but this can vary between individual units. The screen is a bit cloudy throughout, which can be distracting in dark scenes, but it's not too bad. There's some backlight bleed, but it's not too noticeable. Unfortunately, there's no local dimming feature to improve black uniformity.
Unfortunately, as expected for a VA panel, the Amazon Fire TV 4-Series has a poor viewing angle, so it's not well-suited for a wide seating arrangement. The image appears washed out if you're even slightly off-center.
The Amazon Fire TV 4-Series has decent reflection handling. The semi-gloss finish reduces the intensity of direct reflections a bit without smearing them across the screen. Visibility is still an issue in brighter rooms, though, as the TV isn't bright enough to overcome direct sunlight.
Unfortunately, the Amazon Fire TV 4-Series has terrible accuracy out-of-the-box, even with the most accurate settings. The color temperature is very cool, despite using the 'Warm' setting, and there are noticeable issues with every color and the white balance. Gamma is pretty close to our target of 2.2 for a dark room, though, but bright scenes are over-brightened a bit.
The Amazon Fire TV 4-Series has terrible accuracy after calibration. Originally, the TV didn't have any calibration settings, but it received 1-point white balance settings with firmware 18.104.22.168 and newer, but sadly it doesn't improve the accuracy much. The color accuracy, white balance, and gamma are all slightly improved, but not by much. Overall, don't expect to see an accurate image if you get this TV.
You can see our recommended settings here.
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. Even adjusting all of the upscaling settings didn't fix anything.
The Amazon Fire TV 4-Series does a decent job upscaling 720p content, including most cable TV channels, but like with 480p content, it cuts the image slightly and expands it to fill the screen.
1080p content, including Blu-ray movies, is upscaled well. The aspect ratio issue with 480p and 720p content isn't an issue with 1080p content.
Like most TVs on the market with VA panels, the Amazon Fire TV 4-Series uses a BGR (Blue-Green-Red) subpixel layout instead of the traditional Red-Green-Blue layout. 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.
Unfortunately, the Amazon Fire TV 4-Series has just an alright color gamut. It can't display a wide color gamut for the latest HDR content, and tone mapping is off in the DCI P3 and the Rec. 2020 color spaces. The Insignia F50 QLED, with its quantum dot panel, delivers a much wider range of colors.
Unfortunately, due to the narrow color gamut, the Amazon Fire TV 4-Series has disappointing color volume.
Unfortunately, this TV has mediocre gradient handling. There's noticeable banding in every color. The Gradation Clear setting helps to smooth out banding, especially with the 'High' setting, but this can cause a loss of fine details in high-quality content.
The above photo and results are with a 1080p resolution to be consistent with other reviews, including the Amazon Fire TV Omni Series. However, this TV has worse gradient handling with 1080p signals than 4k signals. You can see that it looks like there's 8-bit banding with a 1080p resolution. The same thing happens with the Omni Series TV. The gradient results with a 4k resolution are below, and you can also see how there's much less banding:
If you're streaming content, it's best to leave it on a 4k resolution to get the least banding possible.
Thankfully, there are no signs of temporary image retention on our unit. This is rarely an issue with modern LED TVs.
We don't expect VA panels to experience permanent image retention, as the VA panel in our long-term test appears immune.
Unfortunately, the Amazon Fire TV 4-Series has a mediocre response time, so there's considerable blur in fast scenes. Like most VA-type panels, dark objects are significantly slower, resulting in black smearing behind fast-moving dark objects.
Unfortunately, the Amazon Fire TV 4-Series uses pulse-width modulation to dim the backlight. There's noticeable flicker at all backlight levels below the maximum. This flicker causes duplications in motion, and it can bother some people.
This TV doesn't have an optional backlight strobing feature, commonly known as black frame insertion, but there's flicker at all backlight levels below the maximum.
The Amazon Fire TV 4-Series has an optional motion interpolation feature, which can improve the appearance of low frame rate content. The feature is okay, but it can't handle fast-moving content well, and there are noticeable artifacts and halos in some content. It's also a bit choppy when the camera is moving.
Thanks to the fairly slow response time, this TV has very little stutter when watching movies.
Surprisingly, the Amazon Fire TV 4-Series can remove judder from all sources.
The Amazon Fire TV 4-Series has a basic 60Hz panel, and it doesn't support any variable refresh rate features.
The Amazon Fire TV 4-Series has fantastic low input lag, as long as you're in 'Game' Mode. Unfortunately, 'PC' Mode and any mode other than 'Game' has extremely high input lag.
Unfortunately, the Amazon Fire TV 4-Series can't display proper 4:4:4 chroma with any supported resolution. 4k @ 60Hz is displayed properly, but when a chroma 4:4:4 signal is sent, text looks blurry.
Update 12/20/2021: This TV does have an automatic low latency mode, known as ALLM. No additional settings are required.
This TV only supports the basic 4k @ 60Hz formats with/ both of the new consoles. It supports very few advanced gaming features, but it automatically switches into 'Game' Mode when you start playing a game.
Although advertised to have one HDMI 2.1 port, the Amazon Fire TV 4-Series only supports HDMI 2.0. The HDMI 2.1 port advertised only supports eARC, which is part of the HDMI 2.1 specifications but doesn't require any extra bandwidth over HDMI 2.0.
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.
Unfortunately, like almost every TV on the market, there are ads throughout the home interface and content store, and you can't disable them.
The app store has a great selection of additional apps to download, and you can also cast content from your mobile device.
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.
There's a single button located beneath the Fire TV logo along the bottom bezel. You can use it to turn the TV on/off or to change inputs.
