Our verdict
6.7
Overall rating
The mid-range television segment is growing increasingly, and the TCL C75B shows that you can get really solid equipment in this price range. This model is clearly designed with gamers in mind – the HDMI 2.1 port offers a lot of possibilities, providing VRR, ALLM, and impressive refresh rates of 144 Hz in 4K (or 240 Hz in Full HD), which will surely satisfy both gaming and sports fans. The TV's interface is pleasant and intuitive, mainly thanks to the Google TV system. Although you may encounter minor stutters, the wealth of available applications and features compensates for it – practically everything we need is within reach or even within voice command if we want to speak to the remote in Polish. As for image quality, the TCL C75B also performs well. Thanks to the VA panel, it boasts quite good contrast, and the presence of Dolby Vision allows you to enjoy nice HDR effects, even if the brightness doesn't blow you away. Of course, it's not a device without flaws – despite the fast panel, there is some motion blur, and the lack of traditional features (like recording to USB) 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.

The TV TCL C75B tested by us in size X" is equipped with a VA panel, which naturally provides quite decent contrast results – and this is what we observed during our tests. On each test pattern, the TV achieved a contrast of around 5500:1. This is a result that can be considered very good in this price range. The black in this model is really good, though it is of course far from perfect. Due to the C75B's 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 movie 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 especially apparent during evening screenings with the lights off, when the darker elements of the image are more exposed. It's worth keeping this in mind when choosing a TV in this category, especially if we care about the best quality of black when watching movies at night.

During our luminance test, the TCL C75B "spat out" about 380 nits of brightness. We recorded similar results while watching most of the films we tested. These can be considered average – the television does not perform badly 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 as low brightness values. However, for HDR enthusiasts seeking stronger light effects and greater realism, the C75B may prove insufficient. On the plus side, it's worth mentioning the 95% coverage of the DCI-P3 color palette. This is a very good result that easily suffices to enjoy a wide range of colors in content available on popular streaming platforms. Vivid and rich colors are definitely a strong point of this model.

We tested how the TCL C75B performs with 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 TV, although it struggles with slight shadow boosts when trying to recover details in challenging scenes, maintains decent color consistency. The picture, aside from the "glowing black," which results from the lack of local dimming capabilities, looks quite good. This positive impression is due to the dynamic tone mapping feature, named by the manufacturer as "detailed priority description." We definitely recommend enabling it, as even with the TV's average luminance capabilities, this feature helps it better handle difficult HDR materials. This solution makes watching demanding scenes more enjoyable, even on equipment in this price range.
HDR luminance chart:
By default, as in most of its TVs, TCL equipped the C75B with practically all currently popular types of HDR. Here we 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 average panel brightness, Dolby Vision clearly enhances the picture quality in HDR materials. The TCL C75B is one of those TVs that can fully utilize the potential of dynamic metadata. Thanks to Dolby Vision, we see more details, and the interplay of shadows and image depth 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 many picture modes, but in our opinion, the best choice is the "Film" mode. Although its settings are quite good, the television struggles with certain color reproduction issues. In tests, we noticed that the image had a noticeably pinkish tint compared to what could be considered correct. This effect was particularly noticeable in skin tones, which appeared unnaturally warm. The main culprit of this phenomenon turned out to be the white balance, characterized by an excessive amount of blue and red in both HD and 4K HDR materials.
Another issue was the way brightness was reproduced. 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, lost in total blackness (e.g., the bottom part of the screen in the comparative photo - the area around the actress's ear). Similarly, the situation was reflected in the EOTF curve, which was below the correct value, suggesting that a similar problem may be encountered in 4K HDR content.
Thanks to our experience and the appropriate tools, we decided to take matters into our own hands and see how much could be extracted from this model after professional calibration. Details are described in the next section.
Color reproduction after calibration
8.2/10
After calibrating the TCL C75B, it has clearly improved in terms of color reproduction. Although the TV does not offer many options for adjusting the white balance, we were able to refine its settings significantly. As a result, the image has stopped being overly pink, and the colors now look much more natural and harmonious.
The gamma jump, which was previously a problem, has not disappeared completely, but we managed to significantly reduce it. This has made the details in dark scenes more visible – both in HD and 4K HDR material.
Unfortunately, the lack of local dimming is still noticeable. The "glowing black" effect remains, but that's a limitation of the display itself. Despite this, the colors after calibration look vastly 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 colors is particularly impressive – the television does not disappoint here and delivers a high-quality image.
Some imperfections can be noticed in the brightest areas of the screen, such as in a scene from the movie 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
The TCL C75B has a tonal transition smoothing feature, but unfortunately, we can't praise it. Regardless of the selected level – low or high – tonal transitions in older materials remained visible, as if the feature didn't work at all. It's hard to say something positive about it because, in practice, it seems completely useless.
The image scaling is better. The TV performs quite decently, although on thinner elements, like branches in the background, you can notice slight halos. However, this is not something that significantly interferes with daily viewing.
Unfortunately, a bigger problem turned out to be overscan, which is the trimming of the image edges. In our tests, it happened that news tickers or other elements close to the edge of the screen were cut off. This is definitely something worth paying 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 TV 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 great results, especially for a model from the budget range.
Additionally, 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-step scale, providing a lot of customization options – everyone can set the smoothness to their liking.

The TCL C75B is undoubtedly a television designed for gamers. It offers almost everything that the most demanding console users need. With the implementation of full-bandwidth HDMI 2.1, the television supports features such as ALLM (automatic low latency mode) and VRR (variable refresh rate) – operating across 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 detail representation in HDR-optimized games. The C75B is also equipped with a very convenient interface for gamers in the form of a Game Bar, where you can check all key parameters, such as refresh rate, input lag, or picture settings – all within one click's reach.
In a nutshell: the C75B is an excellent choice for gamers, offering a wide range of features that allow for fully enjoying the capabilities of modern consoles and games.
Input lag
9.8/10
The input lag in 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 gamepad or keyboard practically instantaneous. In the case of 60 Hz, the result is 19 ms – this is not a record-low value, but it still falls within the range where lag is practically unnoticeable during gaming. One could say that we won't feel the difference, which makes this TV a good choice even for more demanding gamers.

TCL C75B is quite a good choice for connecting to a computer. Thanks to its high refresh rate, low input lag, and G-Sync support, 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 definitely appreciate.
For office work, the television also does well. The text is readable, although on a dark background, some imperfections can be noticed – certain fonts look like they are missing pieces of vertical lines. This might be distracting if we work a lot with documents or text editing. However, if the computer is mainly used for gaming or watching movies, the TCL C75B will easily fulfill its role as a monitor. It's 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 weak. This is a typical compromise with VA panels – better blacks at the cost of off-angle visibility. The picture quickly deteriorates in quality when viewed from the side, which is the complete opposite of what IPS panel TVs offer. If we plan to watch the TV mainly head-on, this won't be a big issue. 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
The TCL C75B performs reasonably during the day. The satin matrix somewhat reduces reflections, but it's not an ideal solution. Brightness is also a problem – 350 cd/m² is simply too low for comfortably watching TV in a brightly lit room.
In less extreme conditions, such as in a moderately lit room, the TV manages well. However, if the sun begins to shine directly on the screen in the summer, watching can 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, making it great for watching content from the internet. However, it should be noted that the system can sometimes lag slightly, which may be noticeable during everyday use.
In terms of smart features, the C75B performs well. Voice control using the built-in assistant works smoothly, and with AirPlay and Miracast, it is easy to stream content from a phone or laptop. Bluetooth allows for connecting headphones, controllers, or other devices without any major issues.
However, if someone is counting on classic television features, they may be disappointed. There is no option to record programs to a USB drive or to use picture-in-picture (PiP). TCL has been skipping such features for some time now, which may not appeal to users mainly relying on traditional television.

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