TCL V6C vs TCL C7L

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

TCL C7L is undoubtedly an extremely bright television. In synthetic tests on static images, it can achieve peak brightness levels of around 2800 nits. This is an absolutely phenomenal result, considering the price range it falls into. Unfortunately, the tests with real film scenes are not as spectacular as the measurements of white squares. The brightness in actual HDR shots drops to around 1200 nits in the C7L model. This is still a very good result, as the vast majority of contemporary films are mastered at such a value. However, when small, pinpoint elements appear on the screen, the brightness of those details drastically drops – even to about 400 nits – which diminishes the HDR effect somewhat. The television does this intentionally to maintain a better level of black and prevent a huge glare of light. This is somewhat explainable, but it also shows that Mini LED technology is not completely uncompromising in this regard. As for the HDR effect itself – alongside brightness, colors are obviously key here. And these, thanks to the use of new, "super" quantum dots, are simply outstanding and among the best on the market. The television can achieve around 90% coverage of the ultra-wide color gamut BT.2020 and 99% of the DCI-P3 gamut, easily matching the best RGB MINI-LED screens. Best of all, the C7L can maintain such high color saturation regardless of the scene being displayed, which is often problematic in competing RGB Mini-LED televisions.

We started the color reproduction tests with the Filmmaker mode, which in theory should be the best choice right after taking the television 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 charts, the factory tuning of the V6C is not ideal, although it’s not a disaster either. The biggest problem turned out to be a lack of 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 daily viewing. Looking at the color palette in HDR content, the deficiencies in red are also noticeable, and their source is the relatively narrow coverage of the color space. Of course, every television can be calibrated, so we decided to check how the V6C would perform after such an adjustment.

When it comes to colors straight out of the box, what's new in TCL TVs, including the C7L model, is the addition of a picture mode called Filmmaker Mode. That's significant because until now that mode wasn't available from this manufacturer at all. In theory, as the name suggests, the image in this setting is meant to represent the filmmaker's full intent. From our tests we can confirm that it's without a doubt the best built-in mode on this TV if you care about faithful color reproduction right out of the box. However, we wouldn't say it's perfect. Like most devices on the market, this C7L also had some factory issues. The white balance in Filmmaker Mode tended toward a slightly greenish-yellow tint, caused mainly by an excess of the green channel and a noticeable lack of blue. For the average viewer this won't be a drastic flaw, but if you care about perfect whites, natural skin tones, and getting the full potential out of the structure of these new "super" quantum dots, the TV really begs for professional calibration.

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 TVs we've dealt with in the editorial office. The calibration trials alone took us several working hours and required a lot of patience. We finally managed to slightly warm up the skin tones, which made the faces stop looking like they were straight out of a horror film, a flaw in the factory settings. Unfortunately, that's not the end of it – the TV reacted to our adjustments in white balance in a completely unpredictable way. Where we expected image stabilization in a given area, new errors appeared, and the Color Checker measurements showed deviations that couldn't be rationally explained. It's hard to say whether the software or the construction itself was to blame, but one thing is certain – the V6C offered exceptionally strong resistance. In the end, 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 remained. The TV still flattens the image in HDR material and has significant deficiencies in color reproduction. This is equipment rather intended for everyday TV watching or SDR materials than for cinematic screenings in the highest quality.

After a professional calibration we were able to greatly improve the out-of-the-box Filmmaker Mode. After our adjustments, errors in the ColorChecker test and across the wide color gamut fell below the threshold of human perception, that is below a value of 3, which is a very good result. The TCL C7L definitely benefits from this treatment in terms of color accuracy, and that's hard to argue with. A bit worse, however, is the issue of brightness management in HDR content after calibration. As I described earlier, even though we set this model up correctly, when you play real movie scenes on the TV it can manage its brightness in a rather peculiar way. It often brightens certain elements on the screen contrary to the creator's intent, which can be clearly seen on EOTF charts measured in particular films. Despite this flaw, or rather a specific quirk of this TV, you can't take away one thing: after calibration the C7L was able to reproduce colors accurately.

When it comes to upscaling, the V6C does not bring anything groundbreaking. Lower quality content is heavily sharpened, making the image look very unnatural, sometimes even artificially. This can be partially 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 indeed appears smoother. Unfortunately, its operation is quite aggressive – it heavily interferes with the overall scene, causing the actors in the foreground to start looking like characters from super smooth telenovelas. Therefore, we would not recommend using this option if natural reception of the image is important to us.

This point could, in a sense, be called the Achilles' heel of the C7L. Unfortunately, this TV uses an older MediaTek chipset, the Pentonic 700, which was never known for outstanding digital image processing. You can clearly see this in the operation of the gradual smoothing function, which is responsible for reducing jagged edges and removing digital noise. It simply performs very poorly; when set to low, its effectiveness is practically nonexistent. The only small plus is that the algorithm doesn't further degrade the image or forcefully blur details. Upscaling itself, meaning the scaling of lower-resolution content to 4K, performs a bit better. It's simply adequate and doesn't stand out compared with the competition. That said, there's no denying the C7L would gain a lot in this area if the manufacturer decided to use the newer Pentonic 800 processor, which is now appearing in an increasing number of competing models.

Motion smoothing and motion fluidity is an area where the V6C quickly reveals its limitations. It is a 60 Hz TV, so it was hard to expect miracles here. In dynamic sports scenes, the picture comes off rather average. This is most noticeable in darker scenes, where clear smears and blurry "halos" trail behind 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 motion interpolation, which works while watching movies. Thanks to it, productions recorded at 24 frames per second, meaning practically all cinematic titles as well as 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 full "soap opera effect."

The TCL C7L uses a native 4K panel with a 144 Hz refresh rate, which, at lower resolutions when using a PC, can even reach up to 288 Hz. Those are obviously very high numbers and look impressive on paper, but in everyday use it's worth remembering that almost all dynamic content you play on this TV will still run at around a maximum of 120 Hz. To tame that motion, the TV's menu includes a motion smoothing system called "Motion Clarity." It offers several predefined modes, including a user mode that we strongly recommend setting manually using our tried-and-true guides on our YouTube channel. There are two key sliders available there. The first, "Blur Reduction," reduces smearing and improves sharpness in dynamic 60-fps material, such as sports broadcasts. The second slider, "Flicker Reduction," lets you add artificial frames to movies and TV series shot at cinematic 24 or 30 fps. This, of course, allows you to completely eliminate the annoying image judder during camera motion.

Although the V6C is not a television designed with avid gamers in mind, TCL has included a few features that may appeal to more casual users. There is no 120 Hz panel or HDMI 2.1 ports, but there is an ALLM mode that automatically switches the TV to low-latency mode. Additionally, there is a quite practical Game Bar – a simple panel that allows you to view basic parameters, change the picture mode, or even enable a virtual crosshair on the screen. An interesting feature is also the support for Dolby Vision Gaming, intended for Xbox Series S/X consoles – a nice addition, though in practice it doesn't offer as much as in more expensive models. However, the biggest problem remains HDR configuration. The HGiG feature, which adjusts the brightness and contrast of games to the panel's capabilities, does not respond as we would expect – the image can end up being overly dark or too flat. As a result, a better solution turns out to be simply playing in SDR mode, where the V6C performs stably and does not try to pretend to be an HDR TV.

When it comes to gaming, the TCL C7L is simply an outstanding TV for gamers. Thanks to two full-bandwidth HDMI 2.1 ports at 48 Gbps, you get access to all the key features required by console owners and users of powerful PCs. It has a well-implemented ALLM mode with very low input lag and VRR frame-sync that works in an impressive range from 48 to 288 Hz. Importantly, unlike some competitors, TCL implemented the console HDR10 HGIG profile correctly and added support for Dolby Vision in games. Rounding out the package is a very well-designed player panel, the Game Bar, which even lets you edit its appearance and change the theme to perfectly match your console’s style. The only thing you can — and should — criticize is that the TV offers only two full HDMI 2.1 ports, while the other two are older HDMI 2.0. That creates a fairly significant logistical problem. Why? Because one of those fast ports also supports eARC (enhanced Audio Return Channel). In practice, that means if you connect a soundbar or a home theater system, you’ll only have one free HDMI 2.1 port left. If you have two consoles at home, or a console and a powerful PC, you’ll unfortunately have to give something up or constantly juggle cables at the back while trying to maintain convenient control of your audio system.
