The TCL 4 Series/S455 2022, or the TCL 4 Series for short, is an entry-level 4k TV released in 2022. It runs the Roku smart interface, which is very simple and easy to use but not as polished as more advanced TV smart interfaces like LG's webOS or Samsung's Tizen OS. As an entry-level TV, it's pretty basic, with no advanced gaming features like VRR or HDMI 2.1 bandwidth. It also has very limited picture and motion processing, with no advanced features like motion interpolation. It's been replaced in 2023 by the TCL S450R, which is available with either the Roku smart interface or the Google TV interface on the TCL S4/S450G.
Our Verdict
The TCL 4 Series Roku TV is okay overall. It's a decent TV for watching movies in a dark room thanks to its high contrast ratio and incredible black uniformity. It doesn't look as good in a bright room or if you have a wide seating arrangement, as it's not very bright and has a narrow viewing angle. These issues also limit its versatility for use as a PC monitor. It delivers a decent gaming experience, but mainly due to its low input lag, as it lacks any advanced gaming features. Finally, it technically supports HDR but doesn't deliver an impactful HDR experience, as it's not very bright and doesn't display a wide color gamut.
- Fantastic native contrast results in deep blacks.
- Decent reflection handling.
- Low peak brightness.
- Colors aren't displayed properly, even after calibration.
The TCL 4 Series 2022 is mediocre for watching shows during the day. The built-in Roku smart interface has a great selection of streaming apps, including many free services, so you're sure to find your favorite shows. Sadly, even though it has decent reflection handling, it's not very bright, so it's best suited for a moderately lit or dark room, as glare from windows or bright lights is distracting. It also has a narrow viewing angle, so it's not a good choice for a wide seating arrangement, as the image degrades at an angle. Unfortunately, it can't upscale or smooth out low-quality or low-resolution content properly, so older shows or anything streaming from a low-bandwidth streaming service is blocky and not very sharp.
- Decent reflection handling.
- Great selection of streaming apps.
- Poor low-resolution signal processing.
- Low peak brightness.
- Image degrades when viewed at an angle.
- Colors aren't displayed properly, even after calibration.
The TCL S455 TV is mediocre for watching sports in a bright room. It has decent reflection handling, but it's not very bright, so glare is distracting in a bright room. It also has a narrow viewing angle, so it's not a good choice for a wide seating arrangement, as the image degrades when viewed at an angle. Unfortunately, it's not very loud, so it's not a good choice for watching the big game with a large group of friends unless you have a separate speaker system or soundbar. It also has just okay gray uniformity, and there's noticeable dirty screen effect in the center, which is distracting when watching sports.
- Decent reflection handling.
- Poor low-resolution signal processing.
- Low peak brightness.
- Image degrades when viewed at an angle.
- Colors aren't displayed properly, even after calibration.
- Distracting dirty screen effect.
The TCL 4 Series S455 is a decent TV for gaming. It has incredibly low input lag, which helps it deliver a very responsive gaming experience. It also has a decent response time, so there's just a bit of blur behind fast-moving objects. Sadly, it lacks advanced gaming features like HDMI 2.1 bandwidth or variable refresh rate support, so it's best suited for casual gamers who prefer fancy visuals over high performance, as it doesn't support 4k @ 120Hz gaming from the latest consoles.
- Fantastic native contrast results in deep blacks.
- Incredibly low input lag.
- Poor low-resolution signal processing.
- Low peak brightness.
- No extra gaming features.
- Colors aren't displayed properly, even after calibration.
The TCL 4 Series Roku TV is an alright TV for watching movies in HDR in a dark room. It has fantastic contrast and incredible black uniformity, delivering deep uniform blacks in a dark room, but it lacks a local dimming feature to improve the appearance of bright highlights. Sadly, HDR adds very little overall, as it's not bright enough for bright highlights to stand out the way the content creator intended, and it doesn't display a wide color gamut, so HDR content looks dull overall.
- Fantastic native contrast results in deep blacks.
- Removes judder from 24p sources and the native apps.
- Incredible black uniformity.
- No local dimming.
- Low peak brightness.
- Can't display a wide color gamut.
- Colors aren't displayed properly, even after calibration.

Unfortunately, it lacks advanced gaming features like 4k @ 120Hz support or variable refresh rate support.

The TCL 4 Series Roku TV is a decent TV for use as a PC monitor. It has incredibly low input lag and a decent response time, so your cursor movements are smooth and responsive. It displays chroma 4:4:4 signals properly to help with text clarity. On the other hand, it has decent reflection handling but mediocre peak brightness, so it's best suited for a moderately-lit or dark room. The image degrades at an angle, so it's important not to sit too close to it, or the sides of the screen will degrade.

Differences Between Sizes And Variants
We bought and tested the 65-inch TCL 4 Series Roku TV, and these results are also valid for the 43, 50, 55, 75, and 85-inch models. There's a Black Friday variant of this TV known as the TCL S45, which performs the same as this TV. This TV is also sold as the TCL S451 and the TCL S453, but not all sizes are available on all three variants. These three models perform the same, but the S453 variant comes with a three-year warranty instead of the 1-year warranty on the other models.
Unfortunately, TCL releases different lineups in different regions, so this specific model isn't sold outside of North America.

The TCL 4 Series/S455 2022 is a bit better than the TCL 4 Series/S435 2020. The 2022 version looks a bit better in a dark room, as it has much better black uniformity, with less cloudiness in dark scenes. The 2022 version also gets a bit brighter, and it supports eARC instead of just ARC, allowing you to pass high-quality lossless audio signals through to your connected soundbar or home theater receiver.
The TCL 4 Series/S455 2022 and the Samsung TU7000 are very similar overall. The TCL is a bit more versatile, as it has more HDMI inputs than the Samsung so you can connect more devices. Both TVs deliver similar picture quality and motion handling, but the TCL can remove judder from 24p sources, like a Blu-ray player, so it's a bit better for movie lovers. On the other hand, the Samsung sounds better, so if you want to watch shows without a soundbar or separate speaker system, the Samsung is a bit better.
The TCL 4 Series/S455 2022 is slightly better than the TCL S4/S450G. The S455 has better black uniformity and higher contrast, so it looks a bit better in a dark room. The S455 also gets slightly brighter, so it's slightly better in a bright room. On the other hand, the newer S450G has better picture processing, so it's a better choice if you mainly watch low-quality or low-resolution content, like old TV shows.
The TCL 4 Series/S455 2022 and the Amazon Fire TV Omni Series are very similar overall. The TCL is a slightly better choice for a darker room, as it has better black uniformity, with less cloudiness in dark scenes. The Amazon, on the other hand, gets a bit brighter, so it can handle a brighter room slightly better.
We buy and test dozens of TVs yearly, taking an objective, data-driven approach to deliver results you can trust. Our testing process is complex, with hundreds of individual tests that take over a week to complete. Most of our tests use specially designed test patterns that mimic real content, but we also use the same sources you have at home to ensure our results match the real-world experience. We use two main tools for our testing: a Colorimetry Research CR-100 colorimeter and a CR-250 spectroradiometer.
