Samsung Q8F vs LG QNED80A6A (IPS)

In terms of brightness, the Samsung Q8F performs surprisingly well for a television without local dimming. It measures up to 500 nits, which practically means that most movie and series scenes look pleasant, and it definitely cannot be accused of lacking the "HDR effect." In films like Life of Pi or The Meg, the screen was able to glow and deliver light effects at a satisfying level. It struggles more during challenging moments—with dark frames containing single bright points. The global dimming used causes the television to darken the image to maintain deep blacks, but at the cost 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 from the brilliance of individual elements, and this should simply be kept in mind. When it comes to color reproduction, the Q8F utilizes quantum dot technology, which broadens the color range. A DCI-P3 coverage of 91% can be considered a decent result, although it is not a record-breaking achievement compared to other QLEDs.

When it comes to image dynamics and brightness, the QNED80A has its feet firmly on the ground. It is not a "light beast" – during our measurements, peak brightness oscillated around 350-400 nits. To put it plainly: these are values that will not allow HDR formats to fully spread their wings. So don’t expect the glare of the sun or car headlights in movies to blind you. However, this TV has a powerful ace up its sleeve that saves the overall view of the image – it is the colors. LG engineers have implemented an advanced filtration system here (technically likely based on a PFS phosphor, marketed as QNED/NanoCell), which does a fantastic job. Thanks to it, despite the average brightness, the screen can generate exceptionally saturated and pure colors. Our instruments showed coverage of the wide DCI-P3 cinema palette at the level of 93-94%. This result outclasses most standard LCD TVs. In practice, this means that when watching 4K HDR content, the image – while not particularly bright – is very plastic, vibrant, and pleases the eye with the depth of colors.

We decided to check the Filmmaker mode because it provided us with the best picture right out of the box. However, this does not mean it was perfect. The white balance had too much blue and red tint, causing the white to take on a slight purple-pink hue. Such an imbalance affected the visibility of practically all colors, as can be seen in the comparison photo below. The brightness characteristic in SDR content was quite well adjusted, although in HDR materials, we noticed that the television did not always manage its global dimming—at times, the screen was too dim, while at other times it suddenly brightened. Fortunately, issues related to colors 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 looks identical. LG engineers once again served us their vision of a "gaming look," which unfortunately has little to do with accuracy. After switching to console, the white balance automatically drifts into very cold areas. The image is dominated by the color blue, making it seem artificially sharpened, and the white is so aggressive that it is almost burned out. This creates an effect that we associate with bright retail modes – everything is supposed to shine and scream "I am digital." While some may like this, we must say it straight: this is not an accurate image. If you care about naturalness, we suggest checking the settings right away and changing the color temperature to a warmer one.

After calibration, we managed to correct the white balance almost to perfection. Older SDR content looks stunning — most errors are within a threshold of 2, which is definitely below the human eye's perception limit. In HDR, we also brought the white balance to the correct level, but a different problem arises here. So why are there still relatively large errors in color reproduction? This is mainly due to the limited color palette and the way the television manages brightness. The applied global dimming technique does not give the user control in the settings, so when analyzing the EOTF curve in HDR films, it is clear that the Q8F can independently modify luminance. This can be considered a certain limitation, but despite this, the image after calibration is still much more enjoyable than in the factory version.

After professional calibration, the QNED80A in the IPS version has changed beyond recognition, especially in "regular" content (SDR). We managed to eliminate the greenish tint and calm down the overly bright gamma. In classic television or older games, color errors (DeltaE) fell below the threshold of perceptibility (value < 2). The image is now consistent, natural, and truly pleasing to the eye. The situation is somewhat more complicated in HDR mode. Although the colors are already in place, the television has trouble perfectly controlling the brightness (EOTF curve). Due to the limitations of edge lighting and the rather poor adjustment options provided by LG in this area, the television's software sometimes "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 image after calibration is a class better than what you saw out of the box.

Let's see how the Q8F handles older content, which often has poor quality. Let's start with the positives: the upscaling, which means raising the image to a higher resolution, works really well. The TV handles both classic television and materials from YouTube without giving the impression that we are dealing with something completely unattractive. Materials in very low resolutions, such as 576p, perform worse — the image can be cropped, and unfortunately, the overscan phenomenon cannot be turned off. However, the digital processing itself looks worse too. The noise reduction function, instead of removing unwanted interference, 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 begin to resemble characters from cheap Turkish soap operas. It is therefore hard to consider this option useful — it's best to leave it completely turned off. Perhaps Samsung will refine the operation of this feature in updates, but for now, it’s difficult to regard 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's different. The QNED80A is great equipment for watching content that isn't perfect. The processor does a great job of upscaling the image, making even older recordings look quite decent on a 4K screen – they are consistent and free of digital noise. An interesting feature is the gradation reduction available in the settings. It is quite effective in combating so-called banding (color banding) in low-bitrate materials. Of course, one should approach it with some caution. Due to the lower computing power of the chip (compared to the premium series), enabling 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 60 Hz panel, it's hard to call the Q8F a television made for gaming or watching sports. The panel isn't particularly fast, making motion blur clearly visible. If you were counting on spectacular, almost "stadium-like" experiences during broadcasts, you might feel a slight disappointment. Fortunately, in the case of movies and series, Samsung has not abandoned motion smoothing features. This is nothing other than a motion smoother that allows improving the fluidity of productions recorded at 24 or 30 frames per second. Thanks to this, one can decide whether they prefer a smoother, "television" image or to maintain a cinematic quality. 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 60Hz refresh rate panel, which in 2025 in the QNED series is quite a disappointment. If you are looking for perfect sharpness in dynamic soccer matches, you might feel a bit unsatisfied. A solution in this situation is the TruMotion system. It allows for artificially adding frames, which smooths out the image in movies and series. In the menu, you will find the 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 mixed up this year with its televisions, but the Q8F is not free from all the confusion with updates and shortcomings. While its older cousin, the Q67D, could still be recommended to casual gamers with a clear conscience, it's hard to find a reason to do so here. Aside from the automatic game mode and the attractively designed Game Bar, we practically get nothing that could attract gamers. The lack of proper HGiG implementation is a big problem, especially since function simply disappeared after the 1126 update. The issue with VRR is even worse. Although it is featured in the manufacturer's brochures and appears in the Game Bar, we couldn't activate it. The Xbox Series X console did not allow it to be activated at all, and the option remained grayed out and inactive. It's hard to praise such a television even to casual gamers, which is a shame because Samsung has had a strong bargaining chip in the gaming segment for years.

In the gaming section, we won't sugarcoat it for you – the QNED80A is not e-sports equipment. The lack of support for 120Hz signal is a fact that must be accepted. However, LG engineers have done everything to squeeze the maximum potential out of this 60 Hz panel, providing gamers with a set of desired features. First and foremost, the television supports VRR (in the range of 48-60Hz) and ALLM. This means that the image is smooth, does not stutter, 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 is 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. This helps us avoid the issue of blown-out clouds, which is unfortunately a plague on cheaper LCD televisions.
