Our verdict

6.7

Overall rating

The mid-range television segment is expanding rapidly, and TCL C75B demonstrates that it’s possible to get really solid equipment in this price category. This model is clearly designed with gamers in mind – the HDMI 2.1 port offers a lot of potential, providing VRR, ALLM, and impressive 144 Hz refresh rate in 4K (or 240 Hz in Full HD), which will certainly please both gaming and sports fans. The TV’s operation is pleasant and intuitive, mainly thanks to the Google TV system. While there may be minor stutters, the wealth of available apps and features more than compensates for this – practically everything we need is at our fingertips or even at the sound of our voice if we wish to talk to the remote in Polish. As for picture quality, TCL C75B also performs well. Thanks to the VA panel, it boasts quite good contrast, and the presence of Dolby Vision allows for enjoyable HDR effects, even if the brightness isn’t mind-blowing. Of course, it isn't without its 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 TV we tested, TCL C75B in size X," is equipped with a VA panel, which naturally provides quite decent contrast results – and that’s what we observed during our tests. On each test pattern, the TV achieved a contrast level of around 5500:1. This is a result that can be considered very good in this price category. The black in this model performs really well, though of course, it’s far from perfect.

Due to the C75B belonging to the mid-range segment, we won’t find local dimming technology here. This is particularly noticeable in more demanding scenes, such as those from the film Sicario 2, where we noticed that the black takes on a navy hue instead of a pitch-black. This limitation of panels without local dimming can be particularly evident in evening viewings with the lights off, when dark elements of the image are more pronounced. It's worth keeping this in mind when choosing a TV in this category, especially if we care about the best quality of black while watching movies at night.

During our brightness test, the TCL C75B "spat out" around 380 nits of brightness. We recorded similar results while watching most of the films we tested. These can be considered average – the TV performs decently in this segment, but around 400 nits is definitely too low to fully experience the magic of HDR effects. Of course, such results are better than those of budget models, which can achieve nearly half the brightness values. However, for HDR enthusiasts seeking stronger lighting effects and greater realism, the C75B may prove insufficient. On the plus side, it's worth mentioning the coverage of the DCI-P3 colour gamut at 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 “Pan” (about 2800 nits)

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 can't be said that the picture looks perfect, but we were expecting much worse results. The TV, although it struggles with slight shadow boosts when trying to recover details in challenging scenes, maintains decent colour accuracy. The picture, apart from the "glowing black" that results from the lack of local dimming capabilities, looks quite good. This positive impression is thanks to the dynamic tone mapping feature, referred to by the manufacturer as "detailed priority description." We definitely recommend turning it on, as even with the TV's average luminance capabilities, this feature helps it cope better with challenging 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 kinds of HDR. Here we find standard HDR10, dynamic Dolby Vision, as well as HDR10+. During testing, we particularly focused on standard HDR10 and the more advanced Dolby Vision. As expected, despite the panel’s average brightness, Dolby Vision clearly improves the picture quality in HDR materials. TCL C75B is one of those televisions that can fully harness the potential of dynamic metadata. Thanks to Dolby Vision, we see more details, and the play of shadows and depth of the image are definitely better than in standard HDR10. This demonstrates how significant an impact advanced HDR formats, combined with dynamic tone mapping, can have on the final visual experience.

Smoothness of tonal transitions

8.2/10

When it comes to tonal transition fluidity, TCL C75B performs really well. It particularly excels in gradation of the darkest colours – here the television does not disappoint and presents a high-quality image.

Some imperfections can be noticed in the brightest areas of the screen, such as in a scene from the film Kingsman (sun in a blue sky). Nevertheless, the final effect should satisfy the vast majority of users.

Review TCL C75B Smoothness of tonal transitions

Image scaling and smoothness of tonal transitions

5/10

Smooth transition function

Image without overscan on the SD signal

TCL C75B has a feature for smoothing tonal transitions, but unfortunately, we cannot praise it. Regardless of the selected level – low or high – tonal transitions in older materials remained visible, as if the feature wasn’t working at all. It’s hard to say anything positive about it, as in practice it seems completely useless.

Image scaling is better. The TV handles it quite decently, although on thinner elements, like branches in the background, you can see slight jaggedness. However, this is not something that significantly hinders everyday viewing.

Unfortunately, a bigger problem turned out to be overscan, or cropping of the image edges. In our tests, it happened that news ticker or other elements close to the edge of the screen were cut off. This is definitely something to pay attention to, especially if we use the TV for watching news programs or content with text on the screen.

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 budget range.

On top of that, there are features for improving smoothness and reducing motion blur in films. The "Motion" option allows for precise adjustment of the effect on a 10-point scale, providing significant personalisation possibilities – everyone can set the smoothness to their liking.

Blur (native resolution, maximum refresh rate):

When it comes to motion blur, the TV performs rather averagely. Although the high refresh rate is impressive, the panel's response time isn't great. In our UFO Test, we noticed a distinct trail following the moving object.

TCL C75B is undoubtedly a television designed with gamers in mind. It has almost everything needed for even the most demanding console users. With the implementation of full bandwidth HDMI 2.1, the TV supports features like ALLM (automatic low latency mode) and VRR (variable refresh rate) – operating within the full capabilities of the TV, up to 240 Hz in Full HD resolution.

Additionally, the television supports advanced HDR technologies, including Dolby Vision and HGiG, which allows for even better detailing in HDR-optimised games. C75B is also equipped with a very convenient interface for gamers in the form of Game Bar, where you can check all key parameters such as refresh rate, input lag, or picture settings – all just a click away.

In one sentence: C75B is a great choice for gamers, offering a wide range of features that fully enable enjoyment of the capabilities of modern consoles and games.

Input lag

9.8/10

The input lag on the TCL C75B is something that truly impresses. With a refresh rate of 144 Hz, the lag is just 9 ms, making the TV's response to our actions on the controller or keyboard practically instantaneous. For 60 Hz, the result is 19 ms – it's not a record low value, but it still falls within a range where the lag is practically unnoticeable during gaming. One could say that the difference is hardly felt, 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 G-Sync support, the television performs exceptionally well in games – both fast-paced and more demanding ones. The image is smooth, and the response to our actions is quick, which gamers will undoubtedly appreciate.

For office work, the television also holds up well. Text is readable, although on a dark background some imperfections can be noticed – some fonts appear as if they 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 movies, TCL C75B will easily serve its purpose as a monitor. It’s a versatile device 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 expense of off-angle visibility. The picture quickly loses quality when viewed from the side, which is the complete opposite of what IPS panel televisions offer. If we plan to watch the TV mainly head-on, this won't be a big problem. However, with a larger number of viewers sitting at different angles, the picture quality may disappoint.

TV efficiency during daytime

4.9/10

Matrix coating: Satin

Reflection suppression: Average

Black levels during daytime: Good

TCL C75B performs okay during the day. The satin display somewhat limits reflections, but it's not an ideal solution. Brightness is also an issue – 350 cd/m² is simply not enough for comfortable viewing in a brightly sunlit room.

In less extreme conditions, for example, in a moderately lit room, the TV does alright. However, if the sun starts streaming directly onto the screen in summer, watching can become tiring. It's worth keeping this in mind when choosing this model.

TCL C75B is a television that primarily relies on the Google TV system. The platform offers access to most popular apps, such as Netflix, YouTube, and Prime Video, making it great for watching content from the internet. However, it's worth mentioning that the system can sometimes stutter slightly, 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 smoothly, and thanks to AirPlay and Miracast, we can easily transfer content from our phone or laptop. Bluetooth allows for effortless connection of headphones, controllers, or other devices.

However, anyone expecting classic television features may be disappointed. There is no option to record programmes on a USB drive or a picture-in-picture (PiP) feature. TCL has been skipping such features for some time, which may not appeal to users who mainly rely on traditional television.

The sound on the TCL C75B is really pleasant, especially at lower volume levels. The bass is noticeable and complements the sound well, 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 use higher volume levels more frequently, it’s worth considering purchasing a soundbar, as the built-in speakers may not meet more demanding situations.

Customising TCL C75B for Different Room Sizes

Selecting the right television depends not only on its specifications but also on the size of the room in which it will be used.
