The TCL 4 Series/S446 2021 is an entry-level 4k TV. It's a basic TV in TCL's 4 Series lineup that includes the TCL 4 Series/S435 2020 and the TCL 4 Series/S434 Android 2020. It's different from the other two 4 Series TVs because it uses the Google TV smart interface, while the S434 uses a similar Android TV interface, and the 4 Series 2020 has Roku. It competes with other entry-level TVs like the Hisense A6G, Toshiba C350 Fire TV 2021, and the Amazon Fire TV 4-Series.

Our Verdict

6.7 Mixed Usage

The TCL 4 Series is okay overall. It's best for watching sports or TV shows during the day in a moderately-lit room. It has a wide viewing angle that makes it a good choice for a wide seating arrangement, as you can move around and still enjoy a consistent image. It's alright for gaming because it has low input lag, but its response time is on the slow side, and it lacks extra gaming features. Unfortunately, it's disappointing for watching movies in a dark room because it has a low contrast ratio and lacks local dimming, so dark scenes don't look very good.

Pros
  • No issues upscaling lower-resolution content.
  • Image remains consistent when viewed from the sides.
  • Good reflection handling.
Cons
  • Low contrast ratio, so blacks look gray and washed out.
  • Low peak brightness.
  • Distracting motion blur behind fast-moving objects.
5.9 Movies

The TCL 4 Series is disappointing for watching movies in dark rooms. It has a low contrast ratio and bad black uniformity, and because there's no local dimming feature, dark scenes don't look very good and blacks look washed out. On the other hand, it upscales lower-resolution movies well, and it can remove judder from most sources, so movies are played back smoothly. There's also very little stutter in slow panning shots thanks to its relatively slow response time.

Pros
  • No issues upscaling lower-resolution content.
  • Removes judder from 24p sources and native apps.
Cons
  • Low contrast ratio, so blacks look gray and washed out.
  • No local dimming feature.
  • Bad black uniformity.
7.6 TV Shows

The TCL 4 Series is good for watching TV shows in bright environments. It performs well in rooms with a few lights around because it has good reflection handling, but it doesn't get bright enough to fight a ton of glare. It upscales older shows on DVD well, with no noticeable issues, and the smart interface has a huge selection of streaming channels available, so you can easily find your favorite shows. Finally, it has a wide viewing angle, so the image remains consistent if you have a wide seating arrangement or like to move around with the TV on.

Pros
  • No issues upscaling lower-resolution content.
  • Image remains consistent when viewed from the sides.
  • Good reflection handling.
Cons
  • Low peak brightness.
  • Disappointing built-in speakers.
7.4 Sports

The TCL 4 Series is decent for watching sports. It has a wide viewing angle, making it a good choice for watching the game with a few friends as the image remains consistent from the sides, so you don't have to fight over the best spot. It has good reflection handling if you want to use it in a room with a few lights, but its peak brightness is disappointing, so glare is still distracting if you have a lot of windows. Also, fast-moving content looks a bit blurry because of the only decent response time.

Pros
  • No issues upscaling lower-resolution content.
  • Image remains consistent when viewed from the sides.
  • Good reflection handling.
Cons
  • Low peak brightness.
  • Disappointing built-in speakers.
  • Distracting motion blur behind fast-moving objects.
6.6 Video Games

The TCL 4 Series is okay for casual gamers. It has very low input lag, ensuring a responsive gaming experience with very little delay between your actions and what you see on the screen. Unfortunately, it has a slow response time, so there's more significant blur and ghosting behind fast-moving objects. It's also limited to a 60Hz fixed refresh rate, with no variable refresh rate support, so it's not ideal for the PS5 or Xbox Series X.

Pros
  • Good reflection handling.
  • Low input lag.
Cons
  • Low contrast ratio, so blacks look gray and washed out.
  • Distracting motion blur behind fast-moving objects.
  • No extra gaming features like HDMI 2.1 bandwidth or variable refresh rate support.
5.5 HDR Movies

The TCL 4 Series is disappointing for watching HDR movies. It only supports HDR10 and not Dolby Vision or HDR10+, and it can't display a wide color gamut. Also, it doesn't get bright enough to make highlights pop. It has a low contrast that makes blacks look gray and washed out, and it lacks a local dimming feature to improve the dynamic range. Overall, HDR looks dull and muted, and adds very little over SDR.

Pros
  • Removes judder from 24p sources and native apps.
Cons
  • Low contrast ratio, so blacks look gray and washed out.
  • No local dimming feature.
  • Low peak brightness.
  • Can't display a wide color gamut.
6.6 HDR Gaming

The TCL 4 Series is alright for HDR gaming. It has low input lag for a responsive gaming experience, but it doesn't have any extra features like HDMI 2.1 bandwidth or variable refresh rate support. Also, it doesn't offer a good HDR experience because it has a low contrast ratio, poor HDR peak brightness, and it can't display a wide color gamut, so highlights and colors don't stand out at all.

Pros
  • Low input lag.
Cons
  • Low contrast ratio, so blacks look gray and washed out.
  • Distracting motion blur behind fast-moving objects.
  • No extra gaming features like HDMI 2.1 bandwidth or variable refresh rate support.
8.1 PC Monitor

The TCL 4 Series is great to use as a PC monitor. Your mouse movements feel responsive thanks to the low input lag, but you may notice some motion blur due to the slow response time. It has a wide viewing angle, so the sides of the screen remain uniform even if you're sitting up close. Finally, it displays chroma 4:4:4 properly, which is essential for clear text from a PC.

Pros
  • Image remains consistent when viewed from the sides.
  • Good reflection handling.
  • Low input lag.
Cons
  • Low peak brightness.
  • Distracting motion blur behind fast-moving objects.

Differences Between Sizes And Variants

We bought and tested the 65-inch TCL 4 Series, and it's also available in 43, 50, 55, 75, and 85-inch sizes. The 65-inch version has an IPS panel, but some of the other sizes use VA panels, which offer better contrast and deeper blacks, but a worse viewing angle.

Size US Model Panel Type VESA Mount Notes
43" 43S446 IPS 200x200  
50" 50S446 VA 200x300  
55" 55S446 IPS 300x300

85" 85S446 VA 600x400 Different stand configuration

Our unit was manufactured in September 2021, and you can see the label here.

Compared To Other TVs

The TCL 4 Series TV is a basic entry-level TV that doesn't deliver good picture quality, as it has a low contrast ratio and it lacks local dimming. However, for a cheap option, it has a few more features than similarly-priced TVs, like motion interpolation, backlight strobing, and judder-removal.

Also see our recommendation for the best TVs under $500, the best smart TVs, and the best budget TVs.

Samsung TU7000
43" 50" 55" 58" 60" 65" 70" 75" 82" 85"

The Samsung TU7000 and the TCL 4 Series/S446 2021 are okay TVs. The units we tested have different panel types: the Samsung has a VA panel with high contrast, while the TCL has an IPS panel with a wide viewing angle, but there are variants with a VA panel instead. Although neither gets bright, the TCL is a better choice for rooms with a few lights around because it has better reflection handling. Both TVs flicker their backlight, which isn't ideal, but the Samsung flickers at 120Hz while the TCL flickers at 150Hz, which results in image duplication. The TCL also removes judder from 24p sources, which the Samsung can't do.

Hisense A6H [A6, A65H]
43" 50" 55" 65" 70" 75"

The Hisense A6H and the TCL 4 Series/S446 2021 are extremely similar. The Hisense is slightly more versatile, as it has more HDMI inputs and a few extra features, including variable refresh rate support for gamers. The TCL is a bit brighter, so if you don't care about gaming features, it has slightly better picture quality and can better overcome glare.

Insignia F30 Series 2022
65" 70"

The differences are minor, but overall, the TCL 4 Series/S446 2021 is a bit better than the Insignia F30 Series 2022. The TCL gets significantly brighter and it has slightly better reflection handling, so it can overcome more glare in a bright room. The TCL also has a faster response time for clearer motion when gaming, and it's better for use as a PC monitor as it can display chroma 4:4:4 properly, which is essential for clear text from a PC.

Amazon Fire TV 4-Series
43" 50" 55"

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.

Toshiba C350 Series 2021
43" 50" 55" 65" 75"

The TCL 4 Series/S446 2021 is a better entry-level TV than the Toshiba C350 Fire TV 2021. Both models we tested have IPS-type panels, but they're each available with VA panels, depending on the size. The TCL has a few more features the Toshiba doesn't have like backlight strobing and motion interpolation features, and it can remove judder from 24p sources. It also displays chroma 4:4:4 with 1080p and 4k signals, and the Toshiba doesn't display it with any signal. Lastly, the TCL doesn't have any issues displaying 720p and 480p content, but the Toshiba has problems with them.

TCL 4 Series/S435 2020
43" 50" 55" 65" 75" 85"

The TCL 4 Series/S435 2020 and the TCL 4 Series/S446 2021 are both part of the same lineup from TCL, but they have different features. The 4 Series 2020 uses Roku TV and has a VA panel with high contrast, while the 4 Series 2021 we tested has an IPS-like panel with wide viewing angles, but there are variants with a VA panel instead, and it has Google TV. The 4 Series 2021 is a better choice for bright rooms because it gets bright and has better reflection handling, and it has a quicker response time. The 4 Series 2021 also has a motion interpolation feature, which the 4 Series 2020 doesn't have, and it has lower input lag for a more responsive gaming experience.

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

The Hisense A6G and the TCL 4 Series/S446 2021 are both okay entry-level TVs. The 65-inch models we tested both have IPS-type panels, but each TV is available in a variety of sizes, and some have VA panels instead. Picture quality is similar between each, except the reflection handling is better on the TCL. The TCL also has motion interpolation and backlight strobing features, both of which the Hisense doesn't have. The Hisense uses Android TV while the TCL has Google TV, and while they're essentially the same interface, Google TV is an upgraded version, so apps and settings open more quickly.

Hisense U6G
50" 55" 65" 75"

The Hisense U6G is much better than the TCL 4 Series/S446 2021, mainly because it has more features, and the units we tested have different panel types. The Hisense has a VA panel with a local dimming feature that allows it to display deep blacks, while the 65-inch TCL we tested has an IPS panel without local dimming, so blacks look gray in the dark. However, that means it has wide viewing angles instead. The Hisense also gets much brighter, allowing it to fight glare, and it has better motion handling thanks to its quick response time.

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

The LG C1 OLED is a high-end TV that's much better than the TCL 4 Series/S446 2021. The LG has an OLED panel that displays perfect blacks with no blooming around bright objects, and it has wider viewing angles. It also has a bunch more gaming features like a 120Hz panel and HDMI 2.1 inputs, allowing you to play high-frame-rate games, and it has better motion handling. The one advantage that the TCL has over the LG is that LED TVs like this one won't suffer from burn-in like on OLEDs.

After two months on our accelerated longevity test, this TV doesn't show any signs of degradation.

Design
Stand

The stand is basic and doesn't support the screen all that well because there's wobble from front to back. It raises the screen enough to place a soundbar in front without blocking the screen. The 85-inch version has a different stand, with two T-shaped feet at the very end of the TV, similar to the one on the TCL R745 QLED.

Footprint of the 65 inch TV: 43.5" x 12.6" x 2" to the bottom bezel (three-inches from the table to the bottom of the screen). It's tall enough that most soundbars won't block your screen.

The build quality is okay. Most of the TV is made of plastic, but the back panel is made of cheap metal and it flexes easily, although this isn't likely to cause any issues. The plastic in the back and on the borders also feel flimsy, and the TV wobbles noticeably from front to back. Overall, it's although there are no significant issues noticeable with it, it feels pretty cheap.

The HDR brightness is poor, as it doesn't get bright enough to make highlights pop. The EOTF doesn't follow the target PQ curve well either, as most scenes are darker than they should be. Near-blacks are raised a bit, so shadow details are maintained but dark scenes look blown out overall.

The TCL 4 Series has okay gray uniformity. The sides of the screen are significantly darker than the center, which is noticeable in any content. There's also some dirty screen effect in the center, which is distracting when watching sports or displaying anything with a large area of uniform colors.

The gradient handling is just decent. There's noticeable banding with most colors, especially darker shades, noticeable in scenes with shades of similar colors, like in a sunset. Setting the Gradation Clear setting to 'Low' or 'High' does a decent job at reducing the banding with the test pattern and in real content, but it also causes the loss of fine details in high-quality content.

Nearly all picture modes flicker at 150Hz if you set the Brightness to anything above '28', but the 'Low Power' mode starts flickering at '37', and 'Smart HDR' doesn't flicker at all. However, we don't expect this to be an issue for most people because setting it to '28' with most picture modes results in such a dim image.

There's a backlight strobing feature, commonly known as black frame insertion, to improve the appearance of motion. It flickers at 60Hz, and it reduces motion blur trail behind fast-moving objects. Keep in mind that the BFI score is based on the flicker frequency, and not the actual performance.

There's a motion interpolation feature to try to improve the appearance of motion when watching low frame rate content like most shows and movies. It looks similar to the TCL 5 Series/S546 2021 QLED, as it handles slow scenes well, but there more artifacts like halos when there are fast-moving objects on the screen.

Since this is a basic 60Hz TV, it doesn't support high frame rate signals from the PS5 or Xbox Series X. However, you can still play 4k games up to 60 fps in HDR10 from either console, and there's an Auto Low Latency Mode that automatically switches the TV into Game Mode when you launch a game from a compatible device.

The frequency response is disappointing. It doesn't get loud, and there's no bass, if at all. Its sound profile isn't that well-balanced either, and it's fine for listening to dialogue, but you'll want to get a soundbar or receiver for the best sound experience.

The distortion handling is decent. There isn't too much distortion unless you're listening to content at its max volume, in which case, there's more. However, this depends on the content, and not everyone may hear it.
