Samsung DU7192 (IPS) vs LG QNED80A6A (VA)

The maximum luminance in HDR materials is 245 nits, which is often surpassed by even lower results. Such values will definitely not be sufficient for comfortable viewing of HDR materials, due to the lack of appropriate image dynamics and colour distortions caused by the low brightness of the unit. Although the manufacturer has equipped its device with an HDR format offering dynamic metadata, HDR10+, which is what we're talking about, is very rarely used compared to Dolby Vision, which Samsung has not yet introduced in its televisions. It’s also worth mentioning that Samsung DU7192 offers only 82% coverage of the wide DCI-P3 colour gamut, which is another reason we shouldn't provide a signal in a wide dynamic range, as colour losses will be very noticeable. Samsung DU7192 delivers high-quality image that will satisfy most users.

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 used throughout the testing process was "Filmmaker". This, like the vast majority of modes, had its flaws. Starting with the most basic graph, which is white balance, we can notice a significant dominance of red colour, both in SDR mode and HDR. Although in the latter there was also some green, which didn’t have a major impact on the overall perception. A graph with such results, in both cases, gives us an image characterised by strong yellowing, clearly visible on whites and on the faces of the actors. Another important graph, if not more important, is gamma. This, which is supposed to control contrast in materials with a standard colour palette, was quite good in factory mode with one "but" regarding the beginning. In the darkest scenes, it was significantly lowered, resulting in strong brightening, which left the film lacking contrast and suspense overall. As we mentioned, HDR materials regarding white balance remained at a similar level. The main change is the EOTF curve graph. At the very beginning, we can observe a bulge, which, just like in the case of gamma, strongly brightened the darkest scenes. However, after that, the graph significantly changed its characteristics and the measured result dived below the reference line, causing the film to lose even more dynamism.

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.

Samsung has equipped even its lowest-end TVs with advanced tools for carrying out the calibration process. So we got to work, and the results of our efforts are more than satisfactory. The white balance, which previously had a strong yellow tint in both scenarios, now looks much, much better, even if there are slight deviations from the norm. The picture will still look significantly cleaner than it did before the calibration process. We managed to model the gamma in SDR materials very well, allowing the image to be as contrasty as the TV permits. The EOTF curve has also changed its face and doesn’t brighten or darken the image in such a drastic manner. However, it is worth mentioning that in the case of HDR materials, the deltaE errors are still very high, but this is due to the unit's insufficient brightness.

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.

Let's return for a moment to the tonal transition smoothing function. We can set it in only two ways - off and auto. As you can easily guess, the first of these causes significant issues with gradation. However, if we set the second option, both movies and series will offer us smooth colour transitions. It is worth mentioning, though, that this function has its drawbacks. It heavily interferes with the director's intent, softens the film grain effect, and worse, often misinterprets small details, blurring them as well. Consequently, we consider that this function does not exist and do not recommend using it, as this is how the smoothness of tonal transitions was tested on the tested display.

The next thing we will check in this paragraph is the image scaling process, which is extremely important when watching material in lower resolution. Unfortunately, as this is the manufacturer's lowest model, this function doesn't work very well. All details are heavily blurred, and a characteristic white halo forms around the characters.

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.

Despite the fact that Samsung DU7192 is the lowest model in the manufacturer's portfolio, it has implemented a motion smoothing system. Although it is quite limited in features compared to higher models, its very existence is a significant plus in the context of competition in a similar price range. The maximum refresh rate that we will give to the tested television is 60 Hz, which is entirely sufficient for films and series, although not when it comes to sports. In the motion smoothing menu, we find two functions responsible for improving smoothness. These are "Motion Blur Reduction" and "Clear Motion (LED)". We'll discuss the latter a bit later. Let's focus on the former, as it is quite mysterious. Unfortunately, despite its presence, we did not find any usefulness. At each of the settings, the picture looked the same, characterised by the typical judder known from materials recorded at 24 fps.

The panel Samsung DU7192 features an average response time. It's worth mentioning that due to this specific type of panel, it is better than VA panels in a similar price range. Therefore, it can be said that it won't be the worst in terms of watching sports.

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.

The Samsung DU7192 television is equipped only with HDMI 2.0 ports, which isn’t surprising considering the device’s price and its consumer profile. Therefore, it’s also logical that we won’t achieve maximum quality on the latest generation consoles. That’s why it only features the most basic options for gamers, namely ALLM. It’s a pity the manufacturer didn’t implement at least a GameBar, as this is now standard, even in lower-end TVs, and could offer significant conveniences in terms of quickly changing settings.

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".
