Hisense A7NQ vs TCL C75B

We checked how the Hisense A7NQ performs with HDR, and there are no surprises here. The luminance graph showed a maximum brightness level of 370 nits. The result? Exactly what one could expect – average. At around 350 nits, HDR does not particularly stand out compared to SDR. Indeed, there is a subtle difference in more brightly lit scenes, but it is not an effect that leaves you stunned. As for the coverage of the wide colour gamut, the result was 92% for DCI-P3 and 70.2% for BT.2020. These are decent values for a TV in this class, which uses a PFS coating – the same one that is sometimes promoted as QLED. Colours look good, but we shouldn’t expect something that competes with the best screens on the market. HDR on the Hisense A7NQ is more of an addition than a "game changer." For those looking for solid image quality on a moderate budget – quite acceptable. However, if we expect full HDR capabilities, it is worth looking at models from the higher price range.

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.

When testing the Hisense A7NQ in Filmmaker mode, we were hoping for compliance with the manufacturer's assumptions, but unfortunately, reality looks different. The main issue, as with most televisions, is white balance. In the case of the A7NQ, we noticed a clear dominance of blue, which affected both lower quality materials and 4K HDR content. The results of the Color Checker tests confirm this, and the comparative images speak for themselves – the leading actress in "factory" mode appears cool and pale. It looks as if she has been drained of life.

As for brightness characteristics, both gamma and the EOTF curve show that the image is excessively bright. As a result, everything appears flat, lacking depth and contrast. This state of affairs definitely does not work in favour of the A7NQ and makes the viewing experience in factory mode leave much to be desired. If we expect natural colour reproduction and appropriate image depth, the A7NQ in Filmmaker mode is unlikely to impress us. It is a television that requires considerable adjustment to bring out its potential.

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.

Hisense A7NQ offers several tools that allow for improved image quality, so we decided to take matters into our own hands and "dig around" in the settings a bit. Thanks to professional tools and measurements, we managed to correct the white balance, eliminating the excessive dominance of blue colour in both HD and 4K materials. This is a significant step forward, as in the Color Checker test, the colour reproduction errors in lower quality content dropped to a much more acceptable level. Unfortunately, the 4K materials still fall short of perfection – the colour inaccuracies are considerable and stem from the limitations of the television.

As for the gamma, we managed to set it at the correct level, which significantly reduced the excessive brightening of the image. However, the issue with brightness characteristics in 4K content remains unresolved – the EOTF curve still shows excessive brightness across the entire screen. It’s possible that correct implementation of dynamic tone mapping could help here, but as we mentioned earlier, this feature in the Hisense A7NQ works rather poorly, rather than being helpful. Nevertheless, the calibration has significantly improved the overall image reception. The director's vision is now much better represented than in the factory settings, which will certainly be appreciated by more demanding viewers.

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.

The Hisense A7NQ impresses with the smoothness of tonal transitions in 4K content, but unfortunately, there is no feature here to improve this aspect in older materials of lower quality. In such cases, colour transitions become more visible, which can slightly detract from the overall image, especially in scenes with a lot of gradients.

When it comes to upscaling, the television performs surprisingly well. The image is noticeably improved, although there are some compromises. It can be seen that the television adds a bit of artificial sharpness, and background elements, such as branches, display slight "jaggies." However, these are details that will primarily catch the eye of those who pay attention to such nuances.

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 Hisense A7NQ is equipped with a 60 Hz panel, which means that dynamic scenes – for example in sports or games – perform rather averagely here. This is standard for this class of equipment, but it must be acknowledged that watching more intense, fast-moving content can leave a lot to be desired. However, when it comes to films, the television offers a motion smoothing feature that operates on a 10-point scale. The "judder reduction" option allows you to tailor the smoothness of the image to your own preferences. At the lowest setting, we get a natural film frame rate, which will please cinema purists. Meanwhile, the maximum setting provides a very smooth, theatrical image that may appeal to those who prefer a more "smoothed" motion.

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.

Hisense A7NQ is a piece of equipment that can pleasantly surprise gamers, although it is not without its flaws. The fact that we have a 60 Hz panel here immediately suggests that the television is not designed for the most demanding gaming scenarios. The motion blur that we described earlier can also be an obstacle, especially in dynamic games.

However, there are a few things that are worth praising. The television supports ALLM (automatic game mode) and VRR (variable refresh rate), which is not always standard in this price range. The biggest surprise, however, is that the A7NQ can display images at 120 Hz – albeit only in Full HD resolution, but nevertheless, it's a significant nod to gamers. This provides the option to choose between smoothness and resolution, which is not obvious in televisions at this price.

A nice addition is the Game Bar, which is clear and practical – all the most important functions are at hand, without digging through the settings. However, it lacks support for HGiG, which may be a disappointment for gamers looking for perfect HDR in games.

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.
