TCL V6C vs Hisense U7S Pro

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.

Let's start with the fact that the U7S Pro is an impressively bright TV. In calibrated mode our test equipment recorded a staggering 2200 nits of peak brightness. That's an excellent result, especially given that this model is positioned more as a mid-range set.

As we know, peak brightness on test patterns is one thing, and real film scenes are another. Unfortunately, in real-world footage the backlight output drops noticeably. In the most demanding moments the TV can still exceed 1000 nits, which is still a great result and sits well within the HDR mastering standards for most films, but the real challenge comes from aggressively tuned local dimming algorithms. Because of them, small bright details, like stars or the moon in a night sky, are noticeably dimmed. The TV seems determined to preserve deep blacks, which is understandable, but sadly this comes at the expense of dynamic range and the overall HDR punch.

Colour reproduction is worth praising. The new U7S Pro is a QLED design that provides very wide colour gamut coverage. Unlike last year's model (U7Q Pro), this year's variant is a genuine QLED rather than a solution based on a PFS filter. As a result, colour saturation has clearly increased, and coverage of the demanding BT.2020 colour space has exceeded 81%.

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.

We tested the U7S Pro, as we always do, in the best factory-tuned picture mode, Filmmaker Mode. The displayed colours can be judged in two ways. The most disappointing was the profile intended for SDR viewing, i.e. classic TV, YouTube and other less demanding content. The image there had a distinct yellow cast, which proved to be a direct result of an incorrectly set white balance. As our charts show, this involved a huge deficiency of the blue component, which drastically affected the overall colour temperature. You can see this clearly on the ColorChecker charts and on the colour palette graphs themselves, where most samples drifted towards yellow. Fortunately, the factory HDR mode performed much better; there the colour errors hovered around a Delta E of 3, which is a really solid result.

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.

We do know, however, that the company Hisense is capable of much more – as previous generations have proven – which is why we simply couldn’t leave the factory flaws of the U7S Pro model unaddressed in everyday content. As always in such cases, we had the television undergo professional calibration. The conclusions? This process brought about a colossal change. After manually adjusting the white balance and compensating for deficiencies in the blue component, the annoying yellow tint disappeared as if by magic. White became naturally clean, and skin tones gained the proper, healthy hue. Importantly, the calibration not only tamed the capricious SDR mode but also maximised the potential of the panel, reducing average colour reproduction errors to values nearly imperceptible to the human eye. The only thing we need to criticise after the whole process is the very nature of the Mini-LED backlighting 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 backlighting doesn’t always work perfectly with the creator’s intent – depending on the scene being watched, the curve can noticeably run either above or below the reference, occasionally disrupting the ideal dynamic of HDR images.

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.

The digital processing of lower-quality signals is at a very high level here, and that's all thanks to the MediaTek Pentonic 800 processor used in the U7S Pro. The upscaling itself also performs well, meaning the TV's ability to upscale lower-resolution signals to 4K is impressive. We didn't notice any unnatural, overly sharp contours on the screen, and our test image of the model simply looked attractive.

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."

The Hisense U7S Pro uses a panel with a maximum refresh rate of 165 Hz at 4K, and in gaming mode it can even hit 330 Hz at Full HD. However, it's worth remembering that these top figures don't mean much in everyday use, because most content still runs at a maximum of 120 Hz (for example when playing on a console). Even so, the TV handles motion quite well and performs respectably for an LCD design.

There isn't much to fault when it comes to smoothness. In the menu you'll find a motion smoothing feature called "Motion Enhancement", which hides two sliders: blur reduction and judder reduction. They let you manually tune the smoothing, which works well for both films and sport, effectively improving the raw TV signal.

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.

If you're planning to connect a console or PC to the U7S Pro, you'll be more than pleased – this TV is great gear for gamers. Hisense hasn't held back, featuring 4 HDMI 2.1 ports with full bandwidth of 48 Gbps. So you don't have to juggle cables, as each port will handle the full suite of features. We have an automatic game mode (ALLM) and VRR, which operates over a wide range from 48 Hz to a whopping 330 Hz. Of course, that 330 Hz is currently just a gimmick for owners of powerful PCs, as consoles will cap at 120 Hz, but it's good to have that headroom for the future. The Game Bar also works really well when gaming. It's a handy menu bar for gamers, where you can quickly change the picture mode, turn on a crosshair in the middle of the screen, and even switch the display aspect ratio to ultra-wide, which PC simulation fans will appreciate. The only downside worth noting is the incorrect implementation of the HGiG format in games. The issue is that the TV ignores instructions from the console regarding the image generated in HDR10 and constantly butts in, trying to "enhance" the image in its own way. This makes proper HDR configuration in the console menu (where brightness is set on the logo/checkerboard) a bit more challenging.
