Samsung Neo QLED QN70F / QN74F / QN77F vs LG QNED80A6A (VA)

QN70F is a television that can positively surprise when it comes to brightness. In ideal testing conditions, it reaches even 800 nits, which – for this price range – is a really solid value. Of course, that’s a result from test patterns, so we decided to check how it performs in practice, on real films. Here, the television somewhat tempers its capabilities. In most of the tested scenes – e.g. in "The Meg" – the actual HDR brightness remained around 500 nits. That’s still a decent result, allowing you to enjoy HDR effects, although it’s far from perfection. On the other hand, we have a QLED screen with a quantum dot layer, which means very good colour reproduction capabilities. Colours are vivid and saturated. QN70F covers about 94% of the DCI-P3 colour space, and in the wider BT.2020 palette, it exceeds 75%, so in this respect, there’s nothing to be ashamed of.

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.

We tested the QN70F in the best default picture mode, which is Filmmaker Mode. And it must be admitted that in this particular test unit, the factory settings performed quite well. The picture was calm, natural, and despite slight deviations – pleasant to watch. The biggest error was a slight dominance of red in the white balance, which caused a slight pinkish tint over the entire scene. However, it wasn't a glaring flaw – rather subtle and only noticeable when directly compared to a properly calibrated screen. A slightly bigger issue arose in the brightness characteristics. The TV tends to lower the brightness of parts of the image that should be displayed brighter. As a result, some details can appear slightly dimmed – they don't completely disappear, but they don't stand out as clearly as they should. Nonetheless, as for a TV in this range and in these settings – we consider the result a good starting point for further calibration.

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.

After calibration, the QN70F shows that it can offer a really high level of colour reproduction. It has managed to nearly perfectly balance the white point, and the values in the Color Checker test dropped below level 3 – that is, below the threshold at which the average eye can notice differences. The image looks natural, and the colours are faithfully reproduced, without excessive saturation or the coolness known from factory settings. It must be acknowledged that Samsung provides very extensive calibration options – not only for enthusiasts but also for professionals. The QN70F takes advantage of this potential and, after appropriate settings, can come close to significantly more expensive models in terms of colour accuracy. The only thing that could still be picked on is the brightness characteristic. There is still a tendency to brighten the smallest sections of the image – particularly those that should remain darker. However, this is a design feature of this model, not a calibration error. Despite this, the final result definitely deserves recognition.

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.

Samsung QN70F offers a distortion reduction feature that improves the smoothness of tonal transitions. In "Standard" mode, it works quite well – smoothing out problematic transitions without significantly interfering with the structure of the image. Film grain is partially removed, but details like texture and skin structure remain visible. "High" mode operates much more aggressively. The smoothing is stronger, but at the cost of a noticeable loss of detail. Therefore, in practice, we recommend sticking with the "Standard" setting or turning off this feature altogether. The improvement in gradation may be less spectacular, but the image retains more naturalness.

When it comes to upscaling low-quality content, the QN70F performs very well. Tests with lower resolution images went really well. Despite some slight aliasing of contours, everything looks clean and clear, even if the original content was very poor quality. It's just a pity that the television has an overscan issue that cannot be completely turned off. As a result, images with very low resolution may be slightly cropped, which is mainly noticeable on subtitles or the interface.

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.

The QN70F is a television with a refresh rate of 144 Hz, which in itself places it among the best when it comes to image smoothness. Whether we're watching fast-paced sports broadcasts or gaming on a console – the picture looks fantastic. There's no sense of stuttering, clipping, or the typical "judder" seen in lower-end models during fast motion. Samsung also allows you to adjust the smoothness to your own preferences. In the picture clarity settings, we find options such as motion blur reduction and judder reduction – each of which can be adjusted independently. This is especially useful when we are watching content with a lower frame rate and want to give it a smoother, more cinematic feel – or conversely, maintain the natural filmic "feel" of 24 frames.

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 QN70F is a really solid choice for gamers. It features four HDMI 2.1 ports with full bandwidth of 48 Gbps, which means full support for gaming in 4K at a refresh rate of 144 Hz. Additionally, it comes with all the essential features we expect today: automatic game mode (ALLM), variable refresh rate (VRR), and a very well-designed, intuitive Game Bar with information on the mode, resolution, and frame rate. The Game Motion Plus feature is also noteworthy, allowing artificial frames to be added to games running at 60 fps or less. It works surprisingly well and improves gameplay smoothness without much delay in many titles – especially those where consoles struggle to maintain a stable frame rate.

[UPDATE] We have updated our Samsung TV tests for the 2025 model year due to the release of software version 1131, which restored the crucial gaming feature HGiG.

Unfortunately, there are also some pitfalls. The lack of support for Dolby Vision mode is not surprising – it’s a standard with Samsung. But the absence of the HGiG feature is much more disappointing. What’s worse, it was removed by a software update, leaving users who previously benefited from it quite shocked. Without HGiG, it’s impossible to manually set the maximum HDR brightness from the console, which results in some games appearing slightly overexposed – especially if the TV misinterprets the tonal range. Why has Samsung, a brand that has set standards in gaming features for years, decided to take such a step? It’s hard to say. At the time of writing the review, the tested TV was operating on software version 1110 – and to be honest, if you’re relying on full support for gamers, it’s better to temporarily hold off on updates.

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".
