Samsung Q8F vs LG QNED80A6A (IPS)

In terms of brightness, the Samsung Q8F performs surprisingly well for a television without local dimming. In measurements, it reaches up to 500 nits, which in practice means that most movie and series scenes look pleasing, and it cannot be accused of lacking the 'HDR effect'. In films such as Life of Pi or The Meg, the screen was able to burst with brightness and deliver a light effect at a satisfying level. It struggles more in difficult moments — during dark scenes with individual bright points. The global dimming used causes the television to dim the image to maintain deep blacks, but at the expense of detail brightness. This is clearly visible in the scene from Sicario 2, where the helicopter lights dropped to around 200 nits. This is a conscious design decision that gives the impression of deeper blacks, but somewhat takes away the brightness from individual elements, and one must simply keep this in mind. In terms of colour reproduction, the Q8F uses quantum dot technology, which widens the colour gamut. A coverage of the DCI-P3 palette at 91% can be considered a decent result, although it is not a record-breaking figure compared to other QLEDs.

When it comes to image dynamics and brightness, the QNED80A firmly stands its ground. It is not a “bright beast” – during our measurements, peak luminance oscillated between 350-400 nits. To put it plainly: these values won't allow HDR formats to fully spread their wings. So, do not expect that the glare of the sun or car headlights in films will blind you. However, this television has a powerful ace up its sleeve that salvages the overall picture impression – and that is the colours. LG's engineers have employed an advanced filtration system (technically most likely based on PFS phosphor, marketed as QNED/NanoCell), which does a fantastic job. Thanks to this, despite average brightness, the screen is capable of generating exceptionally saturated and pure hues. Our instruments showed coverage of the wide DCI-P3 cinema colour palette at a level of 93-94%. This is a result that outclasses most standard LCD televisions. In practice, this means that when watching 4K HDR content, the picture – although not very bright – is very plastic, vivid, and delights the eye with its depth of colours.

We decided to check out the Filmmaker mode, as it provided us with the best image straight out of the box. However, this does not mean it was perfect. The white balance had too much blue and red, resulting in the white taking on a slight mauve-pink hue. Such an imbalance affected the visibility of practically all colours, as can be seen in the comparison photo below. The brightness characteristics in SDR content were quite well adjusted, though in HDR material we noticed that the television did not always manage its global dimming effectively — at times the screen was too dim, while at other moments it could suddenly brighten. Fortunately, issues related to colours can be effectively corrected with calibration tools, so we decided to get to work.

Here, regardless of whether you encounter the VA or IPS version, the situation is identical. LG engineers once again served us their vision of a "gaming look," which unfortunately has little to do with accuracy. When switched to console mode, the white balance automatically drifts towards very cold regions. The image is dominated by the colour blue, which makes it seem artificially sharpened, and the white is so aggressive that it appears burnt out. This creates an effect we associate with vibrant shop modes – everything is meant to shine and scream "I am digital." While some may appreciate this, we must say plainly: the image is not accurate. If you care about naturalness, we suggest you immediately check the settings and change the colour temperature to a warmer one.

After calibration, we managed to correct the white balance to near perfection. Older SDR content looks fantastic — most errors fall within a value range of 2, which is well below the threshold of perceivability for the human eye. In HDR, we also brought the white balance to an acceptable level, but another issue arises here. So why are there still relatively large errors in colour reproduction? This mainly stems from the limited colour palette and the way the television manages brightness. The global dimming technique used does not give the user control in the settings, so when analysing the EOTF curve in HDR films, it is apparent that the Q8F can modify luminance independently. This can be regarded as a certain limitation, but despite this, the picture after calibration is still much more pleasant to view than in the factory version.

After professional calibration, the QNED80A in the IPS version has changed unrecognisably, especially with "ordinary" content (SDR). We managed to eliminate the greenish tint and calm down the overly bright gamma. In classic television or older games, colour errors (DeltaE) have dropped below the threshold of perception (value < 2). The picture is now coherent, natural, and truly pleasing to the eye. The situation is somewhat more complicated in HDR mode. Although the colours are now in place, the television has a problem with perfectly controlling the brightness (EOTF curve). Due to the limitations of edge lighting and the rather meagre adjustment options provided by LG in this respect, the television's software at times "does what it wants," just to mask the imperfections of black and contrast. However, this is not a cause for concern – despite these technical limitations, the picture after calibration is a class better than what you saw out of the box.

Let’s check how the Q8F performs with older content, which often has poor quality. Let's start with the positives: the upscaling, or raising the image to a higher resolution, works really well. The television handles both traditional television and YouTube material quite competently, without giving the impression that we are dealing with something completely unattractive. It performs less well with very low resolutions, such as 576p — the image can be cropped, and unfortunately, the overscan issue cannot be turned off. Moreover, the digital processing itself appears less effective. The noise reduction feature, instead of eliminating unwanted disturbances, smooths out almost everything: film grain (which is desirable for many viewers) disappears along with the texture of the image, and the faces of the actors start to resemble characters from cheap Turkish soap operas. Therefore, it’s hard to consider this option useful — it’s best to leave it completely turned off. Perhaps Samsung will refine the operation of this function in future updates, but for now, it’s difficult to view it as anything other than an unnecessary addition.

It often happens that cheap 4K TVs mercilessly expose the flaws of low-resolution materials. Here, it is different. The QNED80A is great equipment for watching content that is not perfect. The processor does a good job of upscaling the image, making even older recordings look quite decent on a 4K screen – they are consistent and free of digital noise. Interestingly, there is a gradation reduction feature available in the settings. It is very effective in combating the so-called banding in low bitrate materials. Of course, it should be approached with some caution. Due to the lower processing power of the chip (compared to the premium series), turning on this option can sometimes result in unwanted artifacts or blurriness. Despite this risk, we encourage experimentation, as in many cases this feature can save a poor-quality viewing experience.

Due to the applied 60 Hz matrix, it is difficult to call the Q8F a television designed for gaming or watching sports. The panel is not particularly fast, which makes motion blur noticeably visible. If you were hoping for spectacular, even 'stadium-like' experiences during broadcasts, you may feel slightly disappointed. Fortunately, in the case of films and series, Samsung has not abandoned the motion blur reduction feature. This is nothing but a motion smoother that allows you to improve the fluidity of productions recorded at 24 or 30 frames per second. This way, you can decide for yourself whether you prefer a smoother, 'television' image or to maintain a cinematic character. It all depends on the viewer's preferences, and the ability to adjust this parameter is undoubtedly a plus.

In terms of motion reproduction, the QNED80A unfortunately has a tough time. The television is based on a display with a refresh rate of 60Hz, which is quite a disappointment for the QNED series in 2025. If you are looking for perfect sharpness during dynamic football matches, you may feel somewhat unsatisfied. A solution in this situation is the TruMotion system. It allows for artificial frame generation, which smooths out the image in films and series. In the menu, you will find a De-Judder slider – we recommend setting it to a value of 2, 3, or 4. This is the "golden mean" that improves fluidity without turning the film into a soap opera.

[UPDATE] We have updated our 2025 Samsung TV reviews following the release of firmware version 1131, which officially restores the essential HGiG (HDR Gaming Interest Group) support.

It is not entirely clear what Samsung has meddled with this year regarding its televisions, but the Q8F is not free from all the confusion surrounding updates and shortcomings. While its older cousin, the Q67D, could still be recommended to casual gamers with a clear conscience, it is difficult to find a reason to do so here. Apart from the automatic game mode and the attractively designed Game Bar, we receive practically nothing that could attract gaming enthusiasts. The lack of proper HGiG implementation is a significant issue, especially since after the 1126 update, the feature simply disappeared. The situation regarding VRR is even worse. Although it is listed in the manufacturer's brochures and appears in the Game Bar, we were unable to activate it. The Xbox Series X console did not allow activation at all, and the option remained greyed out and inactive. It is hard to praise such a television even to casual gamers, which is a pity, as Samsung had a strong bargaining chip in the gaming segment for years.

In the gaming section, we won't be pulling the wool over your eyes – the QNED80A is not e-sports equipment. The lack of 120Hz signal support is a fact that must be accepted. However, LG's engineers have done everything possible to maximise the potential of this 60Hz panel, providing gamers with a set of desirable features. First and foremost, the television supports VRR (in the range of 48-60Hz) and ALLM. This means that the image is smooth, not choppy, and the television automatically switches to low-latency mode as soon as we pick up the controller. Accessing these options is incredibly simple thanks to the dedicated system overlay – Game Dashboard. It’s also worth appreciating the support for the HGiG format. This is a nod to owners of modern consoles. Although the screen does not support gaming Dolby Vision, HGiG ensures that the television 'understands' how to display games in HDR. As a result, we avoid the problem of blown-out clouds, which is unfortunately a plague on cheaper LCD televisions.
