Hisense A7NQ vs TCL C75B

We checked how the Hisense A7NQ performs with HDR, and there are no surprises here. The luminance chart showed a maximum brightness of 370 nits. The result? Exactly what one could expect – average. At a brightness of around 350 nits, HDR does not stand out particularly compared to SDR. A subtle difference can be seen in more brightly lit scenes, but it’s not a jaw-dropping effect. 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 that uses a PFS coating – the same one that is sometimes promoted as QLED. The colours look good, but let’s not expect anything 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 picture quality on a moderate budget – absolutely acceptable. However, if we expect full HDR capabilities, it is worth looking at higher-end models.

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.

When testing the Hisense A7NQ in Filmmaker mode, we hoped for compliance with the manufacturer's assumptions, but unfortunately, the reality looks different. The main issue, as with most TVs, is the 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 Color Checker test results confirm this, and the comparison images speak for themselves – the main actress appears cool and pale in "factory" mode. It looks as if she has been stripped of life.

Regarding brightness characteristics, both gamma and the EOTF curve show that the image is excessively bright. As a result, everything seems 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 TV that requires significant adjustment to extract its potential.

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.

The Hisense A7NQ offers several tools that allow you to improve 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, colour reproduction errors in lower-quality content dropped to a much more acceptable level. Unfortunately, 4K materials are still far from ideal – colour distortions are considerable and stem from the limitations of the television.

As for gamma, we managed to significantly reduce the excessive brightness of the image set after setting it to the correct level. However, the issue with brightness characteristics in 4K content remains unresolved – the EOTF curve still shows excessive illumination of the entire screen. It is possible that a proper implementation of dynamic tone mapping could help here, but as we mentioned earlier, this feature on the Hisense A7NQ works rather poorly instead of being helpful. Nevertheless, calibration significantly improved the overall image perception. The director's vision is now much better conveyed than in the factory settings, which more demanding viewers will certainly appreciate.

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.

The Hisense A7NQ impresses with smooth tonal transitions in 4K materials, but unfortunately, there is no feature here that would improve this aspect in older materials of lower quality. In such cases, colour merging becomes more visible, which can somewhat spoil the viewing experience, especially in scenes with a lot of gradients.

When it comes to upscaling, the TV performs surprisingly well. The image is clearly improved, although it does come with some compromises. One can notice that the TV adds a bit of artificial sharpness, and elements in the background, such as branches, tend to exhibit slight "jagginess." These are details, however, that will mainly catch the eye of those who pay attention to such nuances.

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.

The Hisense A7NQ is equipped with a 60 Hz matrix, meaning dynamic scenes – for example, in sports or games – are somewhat average here. This is standard for this level of TV, but it must be admitted that watching more intense, fast-moving content can leave a lot to be desired. However, when it comes to movies, the TV offers a motion smoothing feature that operates on a 10-level scale. The "motion blur reduction" option allows you to adjust the fluidity of the image to your own preferences. At the lowest setting, you get a natural film frame rate, which will please cinema purists. On the other hand, the maximum setting provides a very smooth, theatrical image that may appeal to those who prefer a more "smoothed out" motion.

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.

Hisense A7NQ is a device that can pleasantly surprise gamers, although it is not without its faults. The fact that we have a 60 Hz panel immediately suggests that the TV is not designed for the most demanding gaming scenarios. The motion blur we described earlier can also be a hindrance, especially in dynamic games.

However, there are several things worth praising. The TV supports ALLM (Auto Low Latency Mode) and VRR (Variable Refresh Rate), which are not always standard in this price range. The biggest surprise, however, is that the A7NQ can display images at 120 Hz – although only in Full HD resolution, it is still a significant nod to gamers. This allows a choice between smoothness and resolution, which is not obvious in TVs at this price point.

A nice addition is the Game Bar, which is clear and practical – all the main features are at hand without digging through the settings. However, there is a lack of support for HGiG, which may be disappointing for gamers looking for perfect HDR in games.

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.
