TCL V6C vs Hisense U7S Pro

When it comes to HDR, the TCK V6C clearly shows that this is not its strong suit. A peak brightness of around 200 nits makes it difficult to speak of true HDR effects – the image simply remains too dark to extract details in bright scenes or convey the appropriate dynamics. Although the television formally supports many HDR formats, in practice it is not equipped for such demanding content. The lack of additional coatings that enhance colours, such as QLED or PFS LED, further limits the attractiveness of the image – in more spectacular productions, colours can appear 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 cinematic experiences in high quality.

Let's start with the fact that the U7S Pro is an impressively bright television – in calibrated mode, our measuring equipment indicated a staggering 2200 nits of peak brightness! This is an absolutely remarkable result, considering that this model is positioned rather as a mid-range option.

However, as we know, peak brightness on test patterns is one thing, and actual film scenes are another. Unfortunately, in real video materials, the backlight power clearly drops. Although in the most demanding moments, the television can still exceed the 1000-nit barrier – which is still an excellent result, perfectly aligned with the mastering standards of most HDR films – the real challenge comes from the aggressively tuned local dimming algorithms. Because of this, small, bright details such as stars or the moon in the night sky are noticeably dimmed. The television tries at all costs to maintain deep blacks, which is of course understandable, but unfortunately, this comes at the expense of the dynamics and brilliance of the HDR effect itself.

One must commend the colour reproduction. The new U7S Pro is a QLED design that provides very wide coverage of the colour palette. Unlike last year's model (U7Q Pro), this year's variant is a "true" QLED, rather than a solution based on a PFS filter. As a result, the colour saturation has clearly increased, and coverage of the most demanding BT.2020 colour space has surpassed the 81% barrier.

We started our 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 significantly alter the image and spoil its natural character. As you can see from the graphs, the factory calibration of the V6C is not ideal, although it's not a complete disaster either. The biggest issue turned out to be a deficiency in red – the television clearly "cools" the image, which is particularly noticeable on human faces, giving a "corpse skin" effect. This issue was the most bothersome in 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 television can be calibrated, so we decided to check how the V6C would perform after such an adjustment.

We tested the U7S Pro model – as we always do – in the best factory-calibrated picture mode, namely Filmmaker Mode. We can evaluate the displayed colours in two ways. The most disappointing was the profile designed for viewing SDR content, that is, traditional television, YouTube, and other less demanding materials. The picture was clearly yellowed, which turned out to be a direct consequence of a poorly set white balance. As our graphs show, there is a significant deficiency of the blue component, which drastically affected the overall colour temperature. This is clearly visible on the ColorChecker charts as well as on the graphs of the colour palette itself, where most samples leaned towards yellow. Fortunately, the factory HDR mode fared much better – there, the colour errors were around a Delta E value of 3, which is already a really solid result.

My dear friends – we haven’t had such a difficult "calibration battle" in years. The V6C turned out to be one of the most stubborn televisions we have encountered in the editorial office. The calibration attempts alone took us several man-hours and required considerable patience. We finally managed to slightly warm the skin tones, which made faces stop looking like they were pulled straight from a horror film, a complaint regarding the factory settings. Unfortunately, that's not the end of it – the television reacted to our white balance corrections in a completely unpredictable manner. Where we expected stabilisation of the image in a certain area, new errors appeared, and the Color Checker measurements showed deviations that could not be rationally explained. It is hard to determine whether the issue 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 pleasant and natural. However, it must be clearly stated that the design limitations remain. The television still flattens the image in HDR materials and has noticeable deficiencies in colour reproduction. This device is rather intended for everyday television watching or SDR materials than for cinematic viewing in the highest quality.

We know, however, that the company Hisense is capable of much more – as previous generations have demonstrated – which is why we couldn't simply overlook the factory shortcomings of the U7S Pro model in everyday content. As is often the case, the television underwent professional calibration. The conclusions? This process brought about a colossal change. After manually adjusting the white balance and supplementing the deficiencies in the blue component, the annoying yellow tint disappeared as if by magic. White became naturally pure, and skin tones gained the appropriate, healthy hue. Importantly, calibration not only tamed the capricious SDR mode but also allowed us to extract the maximum potential from the panel, reducing average colour reproduction errors to levels nearly imperceptible to the human eye. The only thing we must criticise after the whole process is the very nature of the Mini-LED backlight and its specific interaction with the HDR signal. The aggressively tuned local dimming algorithms significantly interfere with the EOTF brightness curve. As a result, the backlight does not always work perfectly with the creator's intention – depending on the scene being viewed, the curve can noticeably deviate either above or below the reference, which at times disrupts the ideal dynamics of HDR imagery.

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

The digital processing of lower quality signals is at a very high level here, thanks to the MediaTek Pentonic 800 processor used in the U7S Pro. The upscaling performance is equally impressive, meaning the television’s ability to enhance lower resolution signals to 4K. We did not notice any unnatural, sharp contours on the screen, and our test image featuring the model simply looked attractive.

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

The Hisense U7S Pro uses a panel with a maximum refresh rate of 165 Hz in 4K, and in game mode, it can reach up to 330 Hz at Full HD resolution. However, it is important to remember that these highest figures do not significantly matter in everyday use, as most content is still limited to a maximum of 120 Hz (for example, when gaming on a console). Nevertheless, the television handles motion quite well and performs really decently for an LCD construction.

There is little to criticise about the fluidity itself. In the menu, we find a motion smoother called "Motion Enhancement", which hides two sliders: blur reduction and judder reduction. These allow for manual configuration of the smoother, which works well in both films and sports, effectively enhancing the raw television signal.

Although the V6C is not a television designed with avid gamers in mind, TCL has added a few features that might appeal to more casual users. It does not have a 120 Hz panel or HDMI 2.1 ports, but there is an ALLM mode that automatically switches the television to low-latency mode. Additionally, there is quite a practical Game Bar – a simple panel for previewing basic parameters, changing picture modes, or even activating a virtual crosshair on the screen. An interesting feature is the support for Dolby Vision Gaming, intended for Xbox Series S/X consoles – a nice addition, although in practice it does not offer as much as in more expensive models. However, the biggest issue remains the configuration of HDR. The HGiG function, responsible for adjusting the brightness and contrast of games to the capabilities of the panel, does not respond as we would expect – the image can be excessively dark or too flat. As a result, the better solution turns out to be simply playing in SDR mode, where the V6C performs stably and does not try to pretend to be a HDR television.

If you plan to connect a console or PC to the U7S Pro, you will be more than satisfied – this television is excellent equipment for a gamer. Hisense has not spared any expense and has included as many as 4 HDMI 2.1 ports with full bandwidth of 48 Gbps. You won’t need to juggle cables as each port will handle the full set of features. We have an automatic game mode (ALLM) and VRR, which operates in a wide range from 48 Hz to an impressive 330 Hz. Of course, that 330 Hz is currently a gimmick for owners of powerful PCs, as consoles will be limited to 120 Hz, but it’s good to have that buffer for the future. The Game Bar also works very well during gaming. It’s a handy menu bar for gamers, where you can quickly change the picture mode, enable a crosshair in the centre of the screen, and even change the display aspect ratio to ultra-wide without having to exit to the main television settings, which will be appreciated by fans of PC simulators. The only downside worth mentioning is the improper implementation of the HGiG format in games. The issue is that the television ignores instructions from the console regarding the image generated in HDR10 and continues to forcefully interfere with the image it produces, trying to "enhance" it in its own way. This makes proper HDR configuration in the console menu (where you set brightness on symbols/checkerboard) somewhat difficult.
