Our verdict
6.7
Overall rating
The mid-range TV segment is expanding rapidly, and the TCL C75B demonstrates that you can get really solid equipment in this price range. This model has been clearly designed with gamers in mind – the HDMI 2.1 port offers ample scope, providing VRR, ALLM, as well as impressive 144 Hz refresh rates in 4K (or 240 Hz in Full HD), which will surely satisfy both gaming and sports fans. Operating the TV is enjoyable and intuitive, mainly thanks to the Google TV system. Although you may encounter slight stutters, the wealth of available applications and features compensates for that – practically everything we need is at our fingertips or even accessible by voice if we wish to converse with the remote in Polish. As for picture quality, the TCL C75B also performs well. Thanks to its VA panel, it boasts quite good contrast, and the presence of Dolby Vision allows for enjoyable HDR effects, even if the brightness isn't groundbreaking. Of course, it is not equipment without flaws – despite the fast panel, there is some motion blur, and the lack of traditional features (like USB recording) may disappoint some users. Nevertheless, in its price category, the C75B is a very attractive option, especially for those looking for a screen designed for high-level gaming.

Visibility of details in the lights:
The TCL C75B television tested by us in size X" is equipped with a VA panel, which naturally provides quite decent contrast results – and this was also observed during our tests. On each test pattern, the television achieved a contrast ratio of around 5500:1. This is a result that can be considered very good in this price range. The black levels on this model perform really well, although of course, they are far from perfect.
Due to the C75B's belonging to the mid-range segment, we do not find local dimming technology here. This is particularly noticeable in more demanding scenes, such as those from the film Sicario 2, where we observed that the black takes on a navy shade instead of a deep black. This limitation of panels without local dimming can be especially visible in evening screenings with the lights off, when the dark elements of the image are more prominent. It is worth remembering this when choosing a television in this category, especially if we care about the best quality of black while watching films at night.

During our test, the TCL C75B "spat out" around 380 nits of brightness. We recorded similar results while watching most of the films we tested. They can be considered average – the television does not perform poorly in this segment, but around 400 nits is definitely too low to fully experience the magic of HDR effects. Of course, these results are better than those of budget models, which can achieve almost half the brightness values. However, for HDR enthusiasts seeking stronger lighting effects and greater realism, the C75B may prove insufficient. On the positive side, it's worth mentioning the DCI-P3 colour gamut coverage of 95%. This is a very good result that easily suffices to enjoy a wide range of colours in content available on popular streaming platforms. Vivid and rich colours are definitely a strong point of this model.

Scene from the movie “Billy Lynn” (about 1100 nits)
We tested how the TCL C75B handles the most demanding film materials, and we must admit that we were really positively surprised. It cannot be said that the picture looks perfect, but we expected much worse results. The television, although struggling with slight shadow boosts when trying to recover details in more difficult scenes, maintains a decent colour consistency. The image, aside from the "glowing black" which results from the lack of local dimming capabilities, looks quite good. This positive impression is thanks to the dynamic tone mapping feature, named by the manufacturer as "detailed priority description". We definitely recommend enabling it, as even with the television's average luminance capabilities, this feature helps it cope better with difficult HDR materials. This solution makes watching demanding scenes more enjoyable, even on equipment in this price range.
HDR luminance chart:
By default, like in most of its televisions, TCL has equipped the C75B with practically all currently popular types of HDR. Here we will find standard HDR10, dynamic Dolby Vision, as well as HDR10+. During testing, we paid special attention to standard HDR10 and the more advanced Dolby Vision. As expected, despite the panel’s average brightness, Dolby Vision clearly enhances the picture quality in HDR content. The TCL C75B is one of those televisions that can fully leverage the potential of dynamic metadata. Thanks to Dolby Vision, we see more details, and the interplay of shadows and depth of the image is definitely better than in standard HDR10. This shows how significant an impact advanced HDR formats combined with dynamic tone mapping can have on the final visual experience.

Factory color reproduction
7.3/10
TCL C75B offers several picture modes, but in our opinion, the best choice is the “Film” mode. Although its settings are quite decent, the television struggles with some colour reproduction issues. In our tests, we noticed that the image had a noticeably pinkish tint compared to what could be considered accurate. This effect was particularly evident in skin tones, which appeared unnaturally flushed. The main culprit for this phenomenon turned out to be the white balance, characterised by an excessive amount of blue and red in both HD and 4K HDR materials.
An additional problem was the way brightness was rendered. The gamma, which is responsible for the visibility of details in darker materials, was definitely boosted, causing details in the darkest parts of the screen to be invisible, disappearing into complete blackness (e.g., the lower part of the screen in the comparison photo - around the actress's ear). Similarly, the situation was reflected in the EOTF curve, which was below the correct value, suggesting that we might encounter a similar problem in 4K HDR content.
Thanks to our experience and the right tools, we decided to take matters into our own hands and see how much we could extract from this model after professional calibration. We describe the details in the next section.
Color reproduction after calibration
8.2/10
After calibrating the TCL C75B, it has clearly improved in terms of colour reproduction. Although the television does not offer many options for adjusting the white balance, we managed to enhance its settings quite significantly. As a result, the image is no longer excessively pink, and the colours now look much more natural and harmonious.
The gamma jump, which was previously an issue, has not completely disappeared, but we have managed to reduce it considerably. This has made details in dark scenes more visible – both in HD and 4K HDR materials.
Unfortunately, the lack of local dimming is still noticeable. The "blooming black" effect remains, but that is a limitation of the display itself. Nevertheless, the colours after calibration look far better, and the image is much more enjoyable to watch.
Smoothness of tonal transitions
8.2/10
In terms of the smoothness of tonal transitions, the TCL C75B performs really well. The gradation of the darkest colours is particularly impressive – here the television does not disappoint and presents a high-quality image.
Some imperfections can be seen in the brightest areas of the screen, such as in a scene from the film Kingsman (the sun in the blue sky). Nevertheless, the final effect should satisfy the vast majority of users.
Image scaling and smoothness of tonal transitions
5/10
Smooth transition function
Image without overscan on the SD signal
TCL C75B has a tone transition smoothing function, but unfortunately, we cannot commend it. Regardless of the selected level – low or high – tone transitions in older materials remained visible, as if the function wasn't working at all. It's hard to say anything positive about it, as in practice it seems completely useless.
The image scaling is better. The television performs quite decently, although on thinner elements, like branches in the background, you can notice slight jaggedness. However, this is not something that significantly interferes with daily viewing.
Unfortunately, a bigger problem turned out to be overscan, which is cutting off the edges of the image. In our tests, there were instances where news tickers or other elements near the edge of the screen were cut off. This is definitely something to pay attention to, especially if we use the television for watching news programmes or content with text on the screen.

The TCL C75B definitely has something to offer gamers. The television is equipped with a panel that can display images with a refresh rate of 144 Hz in 4K, and even 240 Hz in Full HD. These are really impressive results, especially for a model from the entry-level range.
In addition, there are features for improving fluidity and reducing motion blur in films. The "Motion" option allows precise adjustment of the effect on a 10-point scale, which offers great personalisation possibilities - everyone can set the fluidity as they like.
Blur (native resolution, maximum refresh rate):
When it comes to trailing, the television performs rather averagely. Although the high refresh rate is impressive, the response time of the panel is not very good. In our test with the alien (UFO Test), we noticed a distinct trail following the moving object.

The TCL C75B is undoubtedly a television designed with gamers in mind. It offers nearly everything that even the most demanding console users could need. With the implementation of fully capable HDMI 2.1, the television supports features like ALLM (Automatic Low Latency Mode) and VRR (Variable Refresh Rate) – operating within the full potential of the television, up to 240 Hz in Full HD resolution.
Additionally, the television supports advanced HDR technologies, including Dolby Vision and HGiG, allowing for even better detail reproduction in HDR-optimised games. The C75B is also equipped with a very convenient interface for gamers in the form of Game Bar, where all key parameters such as refresh rate, input lag, and image settings can be checked – all within a single click.
In a nutshell: the C75B is a great choice for gamers, offering a wide range of features that allow users to fully enjoy the capabilities of modern consoles and games.
Input lag
9.8/10
Input lag in the TCL C75B is something that really impresses. At a refresh rate of 144 Hz, the lag is only 9 ms, which makes the TV's response to our actions on the pad or keyboard practically instantaneous. For 60 Hz, the result is 19 ms – while not record-breakingly low, it still falls within the range where delays are practically unnoticeable during gaming. One could say that the difference would not be felt anyway, which makes this TV a good choice even for more demanding gamers.

TCL C75B is quite a good choice for connecting to a computer. With high refresh rates, low input lag, and support for G-Sync, the television performs excellently in games – both dynamic ones and more demanding titles. The image is smooth, and the response to our actions is quick, which gamers will surely appreciate.
For office work, the television also does well. Text is readable, although on a dark background some imperfections can be noticed – certain fonts look as if there are missing pieces of vertical lines. This may be distracting if we work a lot with documents or text editing. However, if the computer is mainly used for gaming or watching films, the TCL C75B will easily fulfill its role as a monitor. It is a versatile piece of equipment that can handle most applications.
Viewing angles
2.7/10
Brightness drop at an angle of 45 degrees: 86%
The viewing angles on the TCL C75B are, unfortunately, very poor. This is a typical compromise with VA panels – better blacks at the cost of side viewing visibility. The image quickly loses quality when viewed from an angle, which is the complete opposite of what IPS panel televisions offer. If we plan to watch the television mainly straight on, this won't be a major issue. However, with a larger number of viewers sitting at different angles, the image quality may disappoint.
TV efficiency during daytime
4.9/10
Matrix coating: Satin
Reflection suppression: Average
Black levels during daytime: Good
The TCL C75B performs moderately during the day. The satin screen somewhat limits reflections, but it's not an ideal solution. The brightness is also an issue – 350 cd/m² is simply too low for comfortable viewing in a brightly lit room.
In less extreme conditions, such as in a moderately lit room, the television manages well. However, if the sun beams directly onto the screen in summer, watching may become tiring. It's worth keeping this in mind when choosing this model.

TCL C75B is a television that is primarily based on the Google TV system. The platform offers access to most popular applications, such as Netflix, YouTube, and Prime Video, which makes it great for watching content from the internet. However, it should be mentioned that the system can sometimes be slightly laggy, which may be noticeable during everyday use.
In terms of smart features, the C75B performs well. Voice control with the help of the built-in assistant works efficiently, and thanks to AirPlay and Miracast, it is easy to stream content from your phone or laptop. Bluetooth allows you to connect headphones, controllers, or other devices without any major issues.
However, if someone is counting on traditional television features, they may be disappointed. There is no option to record programmes onto a USB drive, nor is there a picture-in-picture (PiP) feature. TCL has been omitting such features for some time, which may not appeal to users who primarily use traditional television.

The sound on the TCL C75B is really pleasant, especially at lower volume levels. The bass is noticeable and enhances the sound nicely, but only up to about 40% volume. At higher settings, problems start to arise – the bass causes unpleasant vibrations, and the speakers begin to crackle. If we plan to frequently use higher volume levels, it is worth considering purchasing a soundbar, as the built-in speakers may not cope with more demanding situations.
