TCL C75B vs Hisense U7Q

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.

Since the algorithms responsible for blacks are performing quite well, we expected a similarly good effect regarding brightness and overall HDR quality. Unfortunately – here we have to disappoint you a bit.

The U7Q is a sufficiently bright television – under the best conditions, it can achieve around 800 nits, which indeed impresses on some scenes, especially in scenes like those from the film The Meg. Bright areas can shine, and the HDR effect is noticeable. The problem arises when there are very small, bright elements on a dark background – for example, in Sicario 2 or in the second scene from the film Life of Pi. In such moments, the dimming algorithms work too aggressively. Yes, the blacks look great then, but the brightest points can almost completely disappear, causing the HDR effect to vanish and the details to be barely visible. It's just the nature of this technology in this price segment.

As a consolation, it's worth mentioning that the U7Q is marketed as QLED (in practice, a PFS layer is used, which works very similarly), and it is indeed capable of displaying a wide colour palette – a DCI-P3 coverage of around 94% is a very good result for this class.

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.

We tested the U7Q in the best possible picture mode, which is Filmmaker Mode. This is the mode that is supposed to provide the most "filmic" and creator-intended experience – right out of the box. Unfortunately… even this professionally sounding name does not guarantee a perfect picture.

In our unit, the problem lay in the incorrectly set white balance. Both in HD and 4K content, the picture had too much blue and red, which caused the screen to take on a slightly rosy tint. It didn't look terrible, but it was noticeable – especially in bright scenes and white backgrounds. This alone could perhaps be forgiven, but the biggest problem is managing brightness in HDR content. The EOTF curve from measurements confirms what we saw earlier during scene tests: the television can overly darken the smallest bright elements, causing them to nearly disappear, or on the contrary – excessively brighten the brightest ones, which affects the naturalness of the picture.

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.

Thanks to specialised tools, we managed to correct the colour quality in SDR content to nearly perfection. In materials with lower dynamic range, the delta E errors dropped below 0.5, which can be regarded as an almost reference result. The picture on television, YouTube, or classic Full HD looks really very good after calibration. Alright – but where did we not manage to improve the image so easily? Primarily, it concerns HDR quality content. Although we managed to somewhat 'tame' the white balance and eliminate pink tints in most scenes, unfortunately, we no longer had full control over brightness management. We set the local dimming settings according to the best observations – SDR: Medium, HDR: High – but the U7Q still did everything a bit its own way. There were still cases of excessive dimming or brightening of details that calibration simply could not eliminate. And although the overall reception of the content is significantly better, one must reckon that the U7Q will always have something to say at the end with an 'but'.

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.

There are situations where we would like to smooth out tonal transitions a bit, especially in older materials – those with limited source quality. The U7Q is equipped with a feature called "Smooth and Gradient Image," but unfortunately... it works very poorly. In the "Low" option, the effects are practically unnoticeable, and other settings smooth details but do not improve tonal transitions. The only positive aspect is that the feature does not interfere with film grain, so it does not ruin the natural structure of the image.

Fortunately, upscaling content performs quite well. The image is not excessively sharpened, and there is no artificial clarity – and although it is known that this is not the level of high-end televisions, the U7Q handles displaying really old content in a completely acceptable manner without any issues.

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.

U7Q is indeed a very fast television, just like its more powerful version "PRO". At a resolution of 4K, it supports up to 144 Hz refresh rate, and if someone wants even more – in Full HD, you can achieve up to 240 Hz! This will mainly benefit PC gamers, but it is worth appreciating – it is a rarely seen feature in this price segment. Right from the start, it is clear that the U7Q has been designed with dynamic content in mind, such as games or sport. In films, we are not left "out in the cold" either – the U7Q offers an "Ultra Motion Smoothness" feature, where using two sliders you can adjust whether you prefer a smoother, theatrical image or something closer to a cinematic style with a visible film frame. It is good that, as with most manufacturers, we have a choice here as well and can adjust it to our own preferences.

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.

The Hisense U7Q is a television designed with gamers in mind – and this is immediately evident from its gaming capabilities. It has practically everything you could wish for: variable refresh rate (VRR) – check, automatic game mode (ALLM) – check, and on top of that, high refresh rates of up to 240 Hz in Full HD and support for various resolutions, not just 4K. This is truly a great set of features that makes the U7Q perform well both in fast-paced first-person shooters on consoles and in more demanding titles on PC. Of course – as with most Hisense models – there is a lack of proper implementation of the HGiG feature. It's a shame because HGiG allows console brightness to be matched to a specific television, which in practice makes displaying HDR games according to the creators' intent much easier. Without this, you simply have to reckon with certain limitations in the final HDR image in games.
