Hisense U6NQ vs TCL V6C

Hisense U6NQ offers a stable HDR effect, which is a rarity in TVs with local dimming. On most streaming platforms, in films and series recorded in 4K, the TV delivers consistent performance – in every tested scene, regardless of difficulty level, brightness is around 450 nits. This is a pleasant surprise, as many models in this class exhibit distinct differences – some scenes are well-lit, while others are heavily dimmed by dimming algorithms. However, the Hisense U6NQ prioritises maintaining higher brightness, which comes at the cost of blacks, as noted in the paragraph about the contrast test.

The HDR effect on the U6NQ is satisfying, offering a noticeable 'punch' of light in bright moments, although it's worth remembering the aforementioned blooming, which can be visible in challenging scenes. In terms of colour, the TV also performs adequately – the coverage of the DCI-P3 colour gamut is 89%, while BT.2020 is 71%. While these are not results that would impress more demanding users, for beginners in the world of high-quality materials, the U6NQ is a solid choice. As such, it presents an interesting option as an 'entry-level' TV for home cinema.

When it comes to HDR, the TCK V6C clearly shows that it is not its strong suit. A peak brightness of around 200 nits makes it difficult to talk about true HDR effects – the picture simply remains too dark to bring out details in bright scenes or convey the appropriate dynamics. Although the television formally supports many HDR formats, it is not practically equipped for such demanding content. The lack of additional layers that enhance colors, such as QLED or PFS LED, further limits the appeal of the image – in more spectacular productions, the colours may seem washed out compared to more expensive models. Therefore, the V6C will primarily serve as a television for everyday viewing, YouTube, or SDR content, rather than as equipment for high-quality cinematic experiences.

Hisense U6NQ in Filmmaker mode offers really decent colour reproduction, although it's worth remembering that differences between individual units can be noticeable. The model we tested was pleasantly surprising, especially with HD content in SDR quality. The white balance was correct here, and errors in the range of 3–4 ΔE should be acceptable for the average viewer. The television performed slightly worse in reproducing colours with 4K HDR material. The dominance of blue tones led to unnatural cool shades on the Colour Checker chart, giving the image a "store" character. Combined with issues in brightness characteristics – gamma and EOTF curve caused some parts of the image to be too dark – the Filmmaker mode in this case loses some of its credibility. Although the factory settings of the tested unit deserve praise, particularly in SDR, there were still minor shortcomings that would require adjustments to fully utilise the television's capabilities.

We started colour reproduction tests with the Filmmaker mode, which in theory should be the best choice straight out of the box. It certainly performs better than the Eco or Dynamic modes, which heavily interfere with the image and spoil its natural character. As you can see in the graphs, the factory tuning of the V6C is not ideal, although it's not a disaster either. The biggest issue turned out to be a lack of red – the TV clearly "cools" the image, which is especially noticeable on human faces, giving a "zombie skin" effect. This particular issue was the most bothersome during everyday viewing. Looking at the colour palette in HDR content, the shortcomings in red are also noticeable, and their source is the relatively narrow coverage of the colour space. Of course, every TV can be calibrated, so we decided to check how the V6C would perform after such an adjustment.

Although the factory settings of the Filmmaker mode on Hisense U6NQ were quite good, we decided to undertake calibration to fully assess the capabilities of this model. Only after such a procedure can one see how the television performs under ideal conditions. In the case of SDR content, which was already at a high level, we managed to further improve the white balance. However, the biggest change came from adjusting the brightness characteristics – gamma was optimised and no longer causes excessive darkening of the image, which improves its naturalness.

For 4K HDR content, calibration also yielded positive results. We eliminated the issue of blue dominance, which resulted in a more balanced and natural image. However, managing brightness in HDR materials remains a more complicated issue. The EOTF curve, although it had problems with image darkening in the 10–30% brightness range under laboratory conditions, reveals other shortcomings in real scenes. The television tends to overly brighten the smallest elements on the screen. As a result, this leads to noticeable halo effects around bright objects. This phenomenon, which we mentioned earlier in the context of contrast and HDR, arises from the technological limitations of the model and is often difficult to eliminate.

In short: although the Filmmaker mode with factory settings performed decently, calibration allowed us to achieve an even better effect – minor adjustments resulted in a more balanced image, particularly in HDR content. For users seeking the highest quality picture, calibration will be a beneficial step.

My dear friends – we haven't faced such a difficult "calibration battle" in years. The V6C turned out to be one of the most stubborn TVs we've dealt with in the office. The calibration trials alone took us several hours of work and required a lot of patience. We finally managed to slightly warm up the skin tones, which made faces stop looking like they were pulled straight out of a horror film, a common issue with the factory settings. Unfortunately, that wasn't the end of it – the TV reacted to our adjustments in white balance in a completely unpredictable manner. Where we expected stability in the image in a certain area, new errors appeared, and Color Checker measurements showed deviations that couldn't be rationally explained. It's hard to say whether the fault lay with the software or the design itself, but one thing is certain – the V6C put up exceptionally strong resistance. Ultimately, the calibration brought improvement, especially in SDR content, where the image became more pleasing and natural. However, it must be clearly stated that the design limitations remain. The TV still flattens the image in HDR materials and has noticeable deficiencies in colour reproduction. This is equipment more suited for everyday TV watching or SDR content rather than for cinematic experiences in the highest quality.

With high-quality materials like 4K, tonal transitions on U6NQ look really good – colours blend nicely and the image is consistent. Unfortunately, when we switch to lower resolution content, the television doesn’t offer any extra features that could improve this aspect. An example is the test with the light bulb, where it’s clearly visible that the television struggles with reproducing subtle tonal transitions.

On the other hand, digital processing performs quite well. The image looks lively, is pleasantly soft, and free from excessive artifacts. Moreover, thanks to the sharpness settings, it can be tailored to individual preferences – whether towards a softer or sharper image. Overall, while upscaling lower quality materials could be better, the television handles image processing well.

When it comes to upscaling, the V6C doesn't bring anything groundbreaking to the table. Lower quality content is heavily sharpened, making the image look quite unnatural, at times almost artificial. This can be somewhat alleviated by reducing the sharpness level in the settings, but the effect isn't spectacular. The image still falls short of perfection. The digital processing itself performs better. The function responsible for smoothing tonal transitions works quite effectively, especially at the medium setting, where the image truly appears smoother. Unfortunately, its operation is rather aggressive – it heavily interferes with the overall scene, causing actors in the foreground to start looking like characters from super smooth soap operas. Therefore, we would not recommend using this option if a natural viewing experience is important to us.

Hisense U6NQ offers native refresh rates of 60 Hz at a 4K resolution, but the manufacturer has added a feature that allows for an increase in refresh rate to 120 Hz, at the cost of reducing the resolution to Full HD. This is a solution we have previously seen in TCL televisions, such as C655 or C655 PRO. This gives the user the option – higher motion fluidity or full resolution. This makes sense, especially considering that many new generation console games do not achieve full performance in 4K at 120 Hz.

When it comes to movies, the television is equipped with a motion smoother feature, which allows you to adjust the motion characteristics to your own preferences. This enables a more cinematic effect or increases fluidity in dynamic scenes. Overall, Hisense U6NQ offers sensible solutions in terms of motion fluidity that should satisfy both gamers and movie enthusiasts.

Smoothing and motion fluidity are areas where the V6C quickly reveals its limitations. It's a 60 Hz TV, so it was hard to expect miracles here. In dynamic sports scenes, the image performs rather mediocrely. This is most noticeable in darker scenes, where distinct trails and blurred "halos" follow moving objects, which can be quite distracting. This is definitely a weaker point of this model. Fortunately, there is also a small plus. The V6C is equipped with a motion smoother that works while watching movies. Thanks to it, productions filmed at 24 frames per second, which is practically all cinema titles and series, can look smoother than they were actually recorded. Importantly, the intensity of the effect can be adjusted to personal preferences – from slight smoothing to the full "soap opera effect."

Hisense U6NQ gives the option to choose between 4K at 60 Hz and Full HD with 120 Hz refresh rate. This solution may appeal to gamers who want to decide what is more important to them – higher resolution or smoothness. The TV supports features like ALLM and VRR, which help in providing smoother gameplay. A nice addition is the GameBar – an easy-to-use panel that allows quick adjustments to picture settings and checking statistics. We also find the Dolby Vision Game mode here, which operates with low input lag, a big plus for console enthusiasts. Unfortunately, it lacks HGiG, which could further improve HDR quality in games. Nevertheless, the Hisense U6NQ performs quite well as a gaming TV, especially for those who play occasionally and do not require the highest refresh rate in 4K. It is a solid choice for less demanding users.

Even though the V6C is not a TV designed with avid gamers in mind, TCL has included a few features that may appeal to more casual users. You'll not find a 120 Hz panel or HDMI 2.1 ports here, but there is an ALLM mode that automatically switches the TV into low latency mode. There's also a quite practical Game Bar – a simple panel allowing the preview of basic parameters, changing the picture mode, or even enabling a virtual crosshair on the screen. Another interesting feature is the support for Dolby Vision Gaming, intended for Xbox Series S/X consoles – a nice addition, although in practice it doesn’t offer as much as in more expensive models. However, the biggest issue remains the HDR configuration. The HGiG function, responsible for adjusting the brightness and contrast of games to the capabilities of the panel, doesn't respond as we would expect – the picture can be overly dark or too flattened. As a result, a better solution turns out to be simply playing in SDR mode, where the V6C operates steadily and doesn’t try to pretend to be an HDR TV.
