Samsung DU7192 (VA) vs LG QNED80A6A (VA)

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.

Let's talk now about how this TV shines. If you’re expecting dazzling light effects, we need to cool your enthusiasm. The LG QNED80A is a moderately bright television. Our measurements in most film scenes indicated values around 350-400 nits. That’s not enough to speak of a full, cinematic HDR experience and the feeling of that famous “high dynamic range” that flagship products offer. However, brightness is not everything. Although the QNED80A is not a “light monster,” it makes up for it in another key category: colours. This is where PFS technology comes into play, which LG marketers hide under the name QNED/NanoCell. With this trick, the TV offers a significantly wider colour palette than classic LCD constructions. In our tests, the coverage of the cinematic DCI-P3 palette reached a solid 93-94%. What does that mean for you? That even at lower brightness, when watching films in HDR, the colours will be vibrant, deep, and properly saturated. The image is not washed out but juicy, which is a significant advantage in this price range.

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.

It might seem that since the QNED80A is one model, it should offer the same picture regardless of the version. However, practice shows something completely different. Analyzing the variant with the VA panel in the best factory setting – that is, in Filmmaker Mode – we noticed a specific characteristic. This TV "out of the box" delivers a picture with a clear dominance of red and a deficiency of blue. Overall, it is very warm, almost hot. Many users might describe it as an "overly cinematic" picture, leaning towards sepia. Additionally, there is the issue of gamma curve – the TV has a tendency to slightly and artificially brighten scenes (gamma is too low), which causes the picture to lose some of its plasticity. The good news is that these are not panel errors, but merely software issues. As always in our tests, we performed professional calibration, which completely eliminated these drawbacks, restoring natural white balance and correct saturation.

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.

Was it worth spending time on calibration? Definitely yes. We managed to tame the initial, overly warm white balance and, most importantly, correct the gamma curve. The television stopped artificially brightening scenes, resulting in a deeper image. The biggest gains are visible in SDR content, such as when watching regular television, YouTube, or playing games without HDR. Here, the QNED80A shows its class – colour reproduction errors (DeltaE) fell below a value of 2. In technical terms, this means the errors are essentially invisible to the human eye. The image in everyday use has simply become very attractive, natural, and correct. The difficulties start with HDR content. Although we managed to improve the white balance, the EOTF curve (responsible for brightness at various levels) shows that the television still "interprets" the image in its own way. This results from the nature of the edge-lit backlighting with local dimming and the fact that LG gives the calibrator very little control over this parameter. In short: the television struggles to hide its hardware shortcomings, sometimes ignoring our commands. Nevertheless, the final image is significantly more accurate and pleasant to view than the factory settings, even if it still lacks a bit compared to studio perfection.

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.

In this category, the QNED80A turns out to be a true "dark horse". It's a fantastic, affordable television for those who often watch lower quality content – for example, from traditional cable TV. The processor used here handles upscaling incredibly well, enhancing low resolutions to native 4K. The image after processing is natural, smooth, and most importantly – it is not overly jagged or artificially sharpened. In the menu, we also find a dedicated option for smoothing tonal transitions in low-quality content. This feature works really effectively, eliminating the annoying "banding" of colours during heavy video compression. However, we must remain vigilant. Remember, we are not dealing with the top-tier processor known from flagship OLED models. In more challenging scenes, the system might struggle and introduce minor artefacts or distortions. Nevertheless, it's definitely worth giving this feature a chance, because in the majority of cases, the quality improvement is visible to the naked eye.

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.

We move on to a topic that may be crucial for many. Unfortunately, here we must point out the biggest "Achilles' heel" of the QNED80A model. This television is equipped with a panel that has a native refresh rate of 60Hz. There’s no denying it – at this price, we were hoping for more as we know that Chinese manufacturers can offer 120Hz screens for similar money. Due to this parameter, dynamic scenes in sports or fast-paced games are not the strongest point of this screen. Fortunately, LG has equipped the television with a proven smoothing system called TruMotion. It works quite well with film material (24 frames). We suggest playing around with the De-Judder slider – from our experience, setting it in the range of 2-4 provides the best compromise: motion becomes smoother, yet still looks natural, without the artificial "television theatre" 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.

Since we've already established that the QNED80A is a 60Hz TV, we must say it straight: we won't be gaming here at 120 frames per second at any resolution. Does this disqualify the device in the eyes of gamers? Not necessarily, especially for those "casual" players. LG decided to sweeten this technical limitation by packing in quite a few useful features. We have support for VRR (Variable Refresh Rate) in the range of 48-60Hz and an automatic game mode ALLM, which instantly reduces input lag upon detecting a console. We manage all of this via a very convenient, purple Game Optimizer menu (Player Panel), which has become LG's hallmark. The manufacturer deserves big points for consistency regarding HDR. Although the TV does not support Dolby Vision in games on Xbox consoles, LG adds a well-implemented HGiG standard. Thanks to this, even on a screen with moderate brightness, playing in HDR is clear, and the details in shadows and highlights are accurately rendered, rather than being "clipped".
