Samsung Neo QLED QN70F / QN74F / QN77F vs LG QNED86A / QNED85A / QNED87A

QN70F is a TV that can positively surprise when it comes to brightness. In ideal test conditions, it reaches even 800 nits, which – for this price range – is really solid. Of course, that's a result from measurement test patterns, so we decided to check how it performs in practice, with real movies. Here, the TV somewhat tones down its capabilities. In most of the tested scenes – for example, in "The Meg" – the actual HDR brightness was around 500 nits. That's still a good result that allows you to enjoy HDR effects, although it is far from perfect. On the other hand, we have a QLED screen with a quantum dot layer, which means very good color reproduction capabilities. The colors are vivid and saturated. QN70F covers about 94% of the DCI-P3 color space, and in the wider BT.2020 gamut, it exceeds 75%, so in this regard, there's nothing to be ashamed of.

Against the backdrop of contrast and black, the brightness of the QNED86A and the overall HDR effect performs much better. This is a television that can reach around 700 nits in the best conditions, so in terms of brightness alone, there is nothing to be ashamed of. As a result, scenes with strong lights, explosions, flashes, or bright parts of the landscape look clear and can make an impression. Interestingly, even in more challenging moments with small, contrasting elements on the screen, the television handles their backlighting well, and the details are quite visible. The problem resurfaces when there are a lot of dark tones. The lack of effective local dimming causes black to virtually disappear, and instead, we get a gray glow spreading across the entire screen. This kills the sense of depth and makes the image look flat, as if it lacks a cinematic quality. In bright animations or colorful family films, this won't be an issue because colors and bright light dominate there. But in horrors or productions set in darkness, these limitations are very palpable. As a consolation, it’s worth mentioning that the QNED86A is actually a QLED television with a PFS LED filter, which gives it very good coverage of wide color gamuts. Both the DCI-P3 palette and the wider BT.2020 perform really solid here. This ensures that colors in HDR films are saturated, vibrant, and have the right depth – even if the black itself disappoints, the colors can save the viewing experience and make the image look attractive.

We tested the QN70F in the best default picture mode, which is Filmmaker Mode. It must be said that in this particular test unit, the factory settings performed quite well. The picture was calm, natural, and despite minor deviations, pleasant to perceive. The biggest flaw was a slight dominance of red in the white balance, which caused a slight pinkish tint to the entire scene. However, this was not a glaring flaw – rather subtle and only noticeable when directly compared to a properly calibrated screen. A somewhat larger issue appeared in the brightness characteristic. The television tends to understate the brightness of parts of the image that should be displayed more brightly. As a result, some details can appear slightly dimmed – not so much lost entirely, but not as clearly pronounced as they should be. Nevertheless, as far as a television in this category and in these settings goes, we consider the result to be a good starting point for further calibration.

We primarily tested the QNED86A in Filmmaker mode, which is designed to provide the most accurate picture. Unfortunately, right out of the box, there were quite a few shortcomings. The most noticeable issue was the poorly adjusted white balance – there was a lack of blue, causing the overall image to lean slightly yellow, and at times, even orange. An even bigger problem turned out to be the way the television manages brightness. Due to its technical limitations – namely, local dimming that only works along the edges of the screen – the QNED86A tends to over-brighten entire scenes. This is where the flattening effect we mentioned earlier comes from. Instead of distinct depth and contrast, we get something akin to "boosted brightness," which can strain the eye over time.

After calibration, the QN70F shows that it can offer a really high level of color reproduction. It nearly perfectly balanced the white point, and the values in the Color Checker test dropped below 3 – that is, below the threshold at which the average eye can perceive differences. The image looks natural, and the colors are accurately represented, without excessive saturation or the coolness known from factory settings. It must be said that Samsung provides very extensive calibration options – not only for enthusiasts but also for professionals. The QN70F takes advantage of this potential and, after proper adjustment, can come close to much more expensive models in terms of color accuracy. The only thing one could still criticize is the brightness characteristics. There is still a tendency to brighten the smallest parts 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 effect definitely deserves recognition.

What was saved in the QNED86A6A is undoubtedly the colors. After calibration, the white balance was set with great precision, resulting in deviations on the Colour Checker palette mostly not exceeding the threshold of visibility for the human eye. In other words – the colors finally looked natural, without strange yellow or orange tones that previously ruined the experience. Unfortunately, even the best calibration cannot bypass design limitations. The already mentioned very modest number of local dimming zones and their unfortunate placement made the analysis of the EOTF curve in films still show clear over-brightening of scenes. The image tended to flatten, lacking cinematic depth. Fortunately, this effect is not as noticeable in older productions or SDR content. There, calibration really does its job and allows taming the QNED in such a way that the image can be pleasing. However, the specifics of this design – especially the contrast issues – cannot be entirely overcome.

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

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

If someone is worried about possible "steps" when connecting colors, there is a simple way in the QNED86A. Just turn on the feature called Smooth Gradation and set it to medium level. Then the TV really smooths out all those unwanted transitions – especially in older productions – and does it in such a way that the film grain doesn't disappear, nor do strange artifacts appear. In other words, you can use it without worry.

The upscaling itself also turns out quite well. Of course, there are no miracles here – with lower quality sources, you can observe characteristic jaggedness. Fortunately, there is a sharpness slider in the menu, and if someone prefers a more "softer" image, it can be quickly adjusted to their taste.

The QN70F is a television with a refresh rate of 144 Hz, which puts it at the forefront in terms of image smoothness. Whether we are watching dynamic sports broadcasts or playing on a console, the picture looks very good. There is no feeling of stuttering, chopping, or the typical "tearing" in fast motion that is common in lower-end models. Samsung also allows you to adjust the smoothness to your own preferences. In the picture clarity settings, we find options such as blur reduction and motion smoothing – each of which can be adjusted independently. This is especially useful when watching content with a lower frame rate and we want to give it a smoother, more cinematic character – or on the contrary, maintain the natural film "feeling" of 24 frames.

The QNED86A is equipped with a 120 Hz refresh rate panel, so right from the start, it's safe to say that it's suitable for both sports and gaming. And indeed, this is true – the image looks smooth, and motion blur is not very noticeable. IPS panels have always had some issues with this, and you can sometimes notice slight blurring here as well, especially in very dynamic scenes, but it's not something that ruins watching a match or a fast-paced game. For movie and sports fans, LG has added the traditional TruMotion smoother. In the menu, we have two sliders – one for movies (De-Judder), the other for sports (De-Blur). The first adds missing frames and allows you to adjust the character of motion – from raw, cinematic to more fluid, "theatrical." The second enhances sharpness during dynamic actions, so it's worth turning it up a bit if you're watching a lot of sports.

Samsung QN70F is truly a solid choice for gamers. Here we have as many as four HDMI 2.1 ports with full bandwidth of 48 Gbps, which means full support for gaming in 4K at 144 Hz refresh rate. In addition, we have all the basic features we expect today: auto low latency mode (ALLM), variable refresh rate (VRR), and a very well-designed, intuitive Game Bar with information about the mode, resolution, and frame count.

It's also worth highlighting the Game Motion Plus feature, which allows you to add artificial frames to games running at 60 fps or less. It works surprisingly well and in many titles – especially those where consoles struggle to maintain a stable framerate – it improves gameplay smoothness without significant lag.

Unfortunately, there are also some drawbacks. The lack of support for Dolby Vision mode is not surprising – it's a standard for Samsung. But the much bigger disappointment is the absence of the HGiG feature. What's worse, it was removed in a software update, leaving users who previously used it quite shocked. Without HGiG, you can't manually set the maximum HDR brightness from the console, which results in some games looking slightly washed out – especially if the TV misinterprets the tonal range. Why did Samsung, a brand that has set standards in gaming features for years, decide to take such a step? It's hard to say. At the time of writing this review, the tested TV was running on software version 1110 – and frankly, if you care about full support for gamers, it's better to temporarily hold off on updates.

In terms of gaming, the LG QNED86A6A is a complete tool. It features four HDMI 2.1 ports with full bandwidth of 48 Gb/s, which means that whether you connect a PlayStation 5, Xbox Series X, or a powerful PC – everything will work at full 4K 120 Hz with support for all features. This is a big plus, as some competitors still have only two such ports, which can be problematic with a larger number of devices. It also has VRR, or variable refresh rate, which eliminates screen tearing, and ALLM, which automatically activates game mode when the console is turned on. There’s also Dolby Vision Gaming and a proper implementation of the HGiG format, so titles supporting these formats look more vivid and detailed. Added to all of this is the Game Optimizer – a kind of control center for the gamer. From this level, you can view image parameters in real-time, quickly change modes, activate additional features, or adjust image settings to your preferences. The LG QNED86A6A essentially has everything one can expect from a modern gaming television.
