Samsung DU7192 (VA) vs TCL V6C

On the luminance charts, the peak brightness of the television is around 280 nits. Unfortunately, such a value is too low to fully enjoy the effects of HDR, which require significantly higher luminance. In the tested materials, such as The Meg or Gemini Man, the lack of adequate brightness severely limits the magic of HDR, and details in the brighter parts of the image are not sufficiently highlighted. For users primarily consuming SDR content, this quality level might be acceptable but it is definitely not enough when it comes to HDR. Additionally, a DCI-P3 colour gamut coverage of 82% does not favour presenting HDR content in its full glory. The limited colour range makes it difficult for the television to reproduce vibrant and diverse hues, which is crucial for achieving a cinematic experience.

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.

The best factory mode we relied on during testing turned out to be "Filmmaker." Although it is the mode that most closely aligns with the creators' intent, it still has some imperfections. In the white balance graph for both SDR and HDR, there is a clear dominance of red, resulting in significant yellowing, particularly noticeable in whites and on actors' faces. In HDR mode, there is also a slight dominance of green, which, however, does not have as large an impact on the perception of the image. The gamma, responsible for brightness in SDR materials, performed quite well, but with one serious reservation. In the darkest parts of the image, it was too low, causing excessive brightening of those scenes, depriving the film of drama and contrast. In the case of HDR, the white balance remains at a similar level, but the EOTF curve graph draws attention. At the beginning, the curve noticeably bulges, leading to strong brightening of the darkest scenes. Then, the result sharply drops below the reference line, resulting in an overly dark image and a loss of dynamics in the brighter parts.

In summary, the "Filmmaker" mode, despite its advantages, needs refinement—especially regarding white balance and proper management of brightness in the darkest and brightest parts of the image. In its current form, it may be acceptable for less demanding users, but for viewers expecting precise image reproduction, it may leave much to be desired.

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.

Even with its lower models, Samsung offers advanced image calibration tools, which allow for significant improvement of factory settings. We took on this task, and the results turned out to be more than satisfactory. The white balance, which previously exhibited a strong yellow tint in both SDR and HDR, has been significantly improved. Although minor deviations from the norm can be observed, the overall effect is much cleaner and more natural than before calibration. As a result, whites and skin tones look much better. We were also able to properly model the gamma in SDR content, allowing for maximum contrast that this television can offer. The EOTF curve, responsible for HDR content, has also been improved – the image is no longer brightened or darkened as drastically as it was before calibration. Despite these successes, HDR content still struggles with high deltaE error values. The main reason lies in the limited brightness of the television, which does not allow for a full representation of the dynamics of HDR content. Nonetheless, after calibration, the image is clearly better and much closer to the creators' intent. For users seeking the best possible quality in this class of equipment, calibration is definitely recommended.

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.

The tonal transition smoothing feature works in two modes – 'off' and 'auto'. Turning it off causes gradation issues, while the 'auto' mode provides smooth transitions, but at the cost of grain effect and details, which are often blurred. Due to these limitations, we do not recommend using this feature, as confirmed by our tests conducted with it turned off.

Scaling lower resolution materials in this model is not impressive. Details are blurry, and the edges of objects may contain artifacts. This limitation means the television performs better with higher resolution content.

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.

Even though Samsung DU7192 is the lowest model in the manufacturer's range, it is equipped with a motion smoothing system. While the functionality of this solution is significantly limited compared to more expensive models, its mere presence makes the TV stand out against the competition in this price bracket. The TV supports a maximum refresh rate of 60 Hz, which is sufficient for comfortable viewing of movies and series, but may be inadequate for dynamic content such as sport. In the motion smoothing menu, we find, among other things, a "Vibration Reduction" feature. Unfortunately, its performance leaves much to be desired – regardless of the setting, the image retains the characteristic stutter known from material recorded at 24 frames per second, which means that this feature practically fails to fulfil its purpose.

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."

Samsung DU7192 is equipped with HDMI 2.0 ports, which is expected at this price range. This limitation means there is no support for the full capabilities of the latest generation consoles, such as VRR technology. The TV offers only basic features for gamers – automatic switching to low-latency mode (ALLM), and support for basic HDR for games in HGiG standard. HGiG allows for displaying HDR content in games according to manufacturers' guidelines, however, the limited brightness of the TV does not allow full enjoyment of the effects that this standard offers. Unfortunately, there are no conveniences such as GameBar, which is increasingly common even in cheaper models and significantly facilitates quick adjustment of settings for games. The presence of this feature could significantly enhance the user experience, especially for those who frequently switch display modes.

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.
