The TCL S4/S450G is an entry-level 4k TV released in 2023. It's part of the TCL S4 series of budget TVs, which includes the TCL S4/S470G and offer a limited selection of extra features but are available in a wide variety of sizes. Unlike previous years, TCL is offering the S4 series with two different choices of smart interface; the "G" series of TVs, like this one, run the Google TV smart interface. The "R" models run the Roku smart interface instead.

Our Verdict

6.7 Mixed Usage

The TCL S450G is an alright TV for mixed usage. It's best suited for watching shows or playing games in a moderately-lit room. Despite its good reflection handling, it can't overcome glare in a bright room. It's okay for watching movies or gaming in a dark room, thanks to its high native contrast ratio, but it lacks a local dimming feature to improve contrast. It supports HDR, but this adds almost nothing, as it can't display a wide color gamut, and it's not bright enough to bring out bright specular highlights.

Pros
  • High native contrast for deep blacks in dim scenes.
  • Good reflection handling.
Cons
  • Bad viewing angle.
  • Not bright enough to overcome glare in a bright room.
  • Sub-pixel dithering causes some color issues, especially in games and shadow details.
6.3 TV Shows

The TCL S450G is mediocre for watching shows in a bright room. It has poor peak brightness but good reflection handling, so it can handle some glare in a moderately lit room, but it can't get bright enough to overcome bright reflections. The built-in Google TV smart interface has a great selection of streaming apps to quickly find your favorite shows. Unfortunately, the image fades rapidly at an angle, so it's not a good choice for a wide seating arrangement. It also has limited picture processing capabilities, so it can't do much to clean up low-quality or low-resolution content.

Pros
  • Wide selection of streaming apps.
  • Good reflection handling.
Cons
  • Bad viewing angle.
  • Not bright enough to overcome glare in a bright room.
  • Sub-pixel dithering causes some color issues, especially in games and shadow details.
6.2 Sports

The TCL S450G delivers a mediocre experience when watching sports in a bright room. It has good reflection handling, so it can handle some glare in a moderately lit room, but it can't get bright enough to overcome bright reflections. The response time is okay, but fast action in games looks blurry, and the TV has a narrow viewing angle, meaning the image fades and looks washed out at an angle.

Pros
  • Wide selection of streaming apps.
  • Good reflection handling.
Cons
  • Bad viewing angle.
  • Distracting dirty screen effect in the center.
  • Not bright enough to overcome glare in a bright room.
  • Sub-pixel dithering causes some color issues, especially in games and shadow details.
7.1 Video Games

The TCL S450G is okay for gaming. It has superb low input lag, ensuring a responsive gaming experience with minimal delay between your actions and what you see on the screen. There's also very little difference in picture quality when switching to 'Game' mode. On the other hand, it has a fairly slow response time, so you'll see more blur around fast-moving objects. It's limited to a 60Hz refresh rate and doesn't support any advanced gaming features like VRR.

Pros
  • High native contrast for deep blacks in dim scenes.
  • Low input lag.
  • Good reflection handling.
Cons
  • 60Hz refresh rate and limited gaming features.
  • Sub-pixel dithering causes some color issues, especially in games and shadow details.
6.9 HDR Movies

The TCL S450G is okay for watching movies in a dark room. It has a high native contrast ratio and decent black uniformity, so you don't have to worry about distracting IPS glow or blooming around bright highlights. It can't get very bright in HDR, though, and it lacks a local dimming feature, so bright specular highlights don't stand out. Finally, it can't display a wide color gamut, so most HDR content looks dull and muted.

Pros
  • High native contrast for deep blacks in dim scenes.
Cons
  • No local dimming feature to improve contrast.
  • Poor peak brightness in HDR.
  • Can't display a wide color gamut.
  • Sub-pixel dithering causes some color issues, especially in games and shadow details.
7.3 HDR Gaming

The TCL S450G is just okay for gaming in HDR. It has low input lag and good picture quality in the 'Game' Picture Mode. It also has a high native contrast ratio, which is essential for a good HDR experience. It lacks a local dimming feature, though, and it can't get very bright in HDR, so specular highlights in HDR don't stand out at all. It also can't display a wide color gamut, and HDR adds very little overall.

Pros
  • High native contrast for deep blacks in dim scenes.
  • Low input lag.
Cons
  • No local dimming feature to improve contrast.
  • Poor peak brightness in HDR.
  • 60Hz refresh rate and limited gaming features.
  • Sub-pixel dithering causes some color issues, especially in games and shadow details.
6.6 PC Monitor

The TCL S450G is just okay for use as a PC monitor. It has low input lag, ensuring a responsive desktop experience, but the response time is a bit sluggish, resulting in more noticeable blur around fast-moving objects like a cursor. It has just okay gray uniformity, and there's noticeable dirty screen effect near the center, so it doesn't look good when browsing the web. It also has a bad viewing angle, so the sides of the screen lose uniformity when sitting too close to the screen.

Pros
  • Low input lag.
  • Chroma 4:4:4 is displayed properly for clear text from a PC.
  • Good reflection handling.
Cons
  • Bad viewing angle.
  • Distracting dirty screen effect in the center.
  • Not bright enough to overcome glare in a bright room.
  • Sub-pixel dithering causes some color issues, especially in games and shadow details.
  • 6.7 Mixed Usage

Differences Between Sizes And Variants

We bought and tested the 50-inch TCL S450G which is part of the TCL S4 lineup, and these results are also valid for the 43-, 55-, 65-, 75, and 85-inch sizes. There are a few different models in TCL's S4 series, which share a similar design but slightly different features and picture quality. The TCL S470G is very similar to this one, but has a different panel with a wider color gamut and a wide viewing angle, but much worse contrast. The TCL S450R is a Roku variant of this TV with a slightly different feature set, but similar picture quality. All sizes perform the same, but the 75-inch and 85-inch models have a slightly different stand and an additional USB port.

Our unit was manufactured in April 2023; you can see the label here.

Compared To Other TVs

The TCL S450G is a very basic entry-level TV with okay picture quality and very few additional features. It's cheap, and it performs as expected for a cheap TV. You can get a much better TV by spending just a bit more, but if you don't care about gaming features or picture processing then it's an okay option.

See our recommendations for the best budget TVs, the best TVs under $300, and the best smart TVs.

TCL Q6/Q650G QLED
55" 65" 75" 85"

The TCL Q6/Q650G QLED significantly improves over the lower-end TCL S4/S450G. The Q6 delivers much better picture quality overall and looks better in bright rooms thanks to its higher peak brightness. HDR also looks better on the Q6 thanks to its higher peak brightness and wide color gamut. Finally, the Q6 is better for gaming thanks to the addition of VRR support, ensuring a nearly tear-free gaming experience.

Hisense A65K
43" 50" 55" 65" 75"

The Hisense A65K is much better than the TCL S4/S450G. The Hisense delivers better overall picture quality thanks to its higher peak brightness, better accuracy before calibration, and much wider color gamut. The Hisense gets significantly brighter, so it can handle more glare in a bright room, and this model has better picture processing, which is great if you watch a lot of low-quality or low-resolution content.

TCL 4 Series/S455 2022
43" 50" 55" 58" 65" 75" 85"

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.

Samsung CU7000/CU7000D
43" 50" 55" 58" 65" 70" 75" 85"

For most users, the Samsung CU7000/CU7000D is a bit better than the TCL S4/S450G. The Samsung gets a bit brighter, so it can handle more glare in a bright room, and it has a faster response time, so motion in sports and games has less blur.

Toshiba C350 Series 2023
43" 50" 55" 65"

The TCL S4/S450G is a bit better than the Toshiba C350 Series 2023, although the Toshiba is the brighter TV of the two, making it better overall as a bright room TV. The Toshiba also has a much wider viewing angle, making it a better choice for a wide seating arrangement. However, the TCL has vastly better contrast and black uniformity, so it looks significantly better in a dark room or even in a moderately lit room with its good reflection handling.

TCL S4/S470G
43" 50" 55" 58" 65" 70" 75" 85"

In an odd twist, the lower-end TCL S4/S450G is better than the higher-end TCL S4/S470G. The S450G delivers much better picture quality, with a much higher contrast ratio, resulting in better dark room performance. The S470G has a wider color gamut, so HDR content looks a bit better, and it has a wide viewing angle, which is great if you have a wide seating arrangement. Despite these improvements, the overall picture quality and viewing experience on the S450G is better.

Stand

The V-shaped feet are very basic. They're set near the ends of the TV, so you'll need a large cabinet for the larger sizes if you're not planning on wall-mounting the TV. Sadly, the feet have no alternative position to accommodate a smaller table. The feet don't lift the TV very high, so most soundbars won't fit in front of it without blocking a portion of the screen.

Build Quality

The TCL S4/S450G has mediocre build quality. It's mostly made of cheap plastic, and there's some flex in the plastic panels around the inputs. There are some obvious quality control issues, though, as there are some specs on our panel that you can see in the gray uniformity slide.

The TCL S450G has an excellent native contrast ratio, so blacks are deep in relatively easy, dim scenes. Since it lacks a local dimming feature, blacks appear gray and washed out when very bright highlights are on the screen.

This TV doesn't have a local dimming feature, so it can't adjust the backlight of individual zones to brighten up highlights without impacting the rest of the image. But this means that there's no distracting flicker or brightness changes as bright highlights move between zones.

The PQ EOTF tracking on this TV is surprisingly great. Most HDR content is displayed close to the brightness level intended by the content creator. Near-blacks are raised, so some shadow details appear washed out, mainly due to the lack of a local dimming feature. It's also severely limited by the TV's low peak brightness, so bright scenes are too dim. The EOTF tracking is consistent with content mastered at various brightness levels, but content mastered at 4,000 nits starts to tone map a bit earlier than content mastered at a lower level.

The TCL S450G has an okay color gamut, but it can't display the wide range of colors that HDR is intended for. The tone mapping is surprisingly good, so fine details are preserved in saturated colors. Saturated greens and blues are a bit off. The next model up in TCL's lineup, the TCL S4/S470G offers a much wider color gamut thanks to the inclusion of a PFS Phosphor coating.

The TV uses a BGR (Blue-Green-Red) subpixel layout instead of the traditional RGB layout. It doesn't cause any issues for video content, but if you plan to use this TV as a PC monitor, non-RGB subpixel layouts impact text clarity, and text looks slightly blurry. You can read about it here. Unfortunately, there's noticeable sub-pixel dithering, as every other blue subpixel is dimmer than the rest. This causes some noticeable issues with certain content, especially shadows in games.

The TV's backlight uses pulse width modulation (PWM) to dim the backlight at low brightness levels. This causes noticeable flicker, and since it flickers at an unusual frequency, it's very distracting and causes motion issues. It's flicker-free with a backlight setting above '31' in most modes. The 'Low Power' mode is flicker-free above '40', and it's always flicker-free in the 'Smart HDR' mode. Since this TV can't get very bright, almost everyone will always use this TV above those brightness settings, so you'll never notice this issue.

The TCL S450G supports eARC, allowing you to pass high-quality, uncompressed audio to a compatible receiver. While the TV can pass DTS 5.1 through ARC and Optical connections, it can't pass the full 7.1 DTS:X or DTS-HD formats through eARC, which is disappointing as many UHD Blu-ray discs use these as their main audio track. If you have a 7.1 channel or higher speaker setup, connect your player to your receiver for the best audio quality.

The TCL S450G has a sub-par frequency response. It gets loud but severely lacks bass and can't reproduce sounds in the high treble range well. Most dialogue is clear and easy to understand, and there's little compression at max volume.
