Samsung QLED Q80D vs LG QNED86A / QNED85A / QNED87A

In the context of HDR, the Samsung Q80D television achieves very positive brightness results in the tested film scenes, where the frame is filled with light, reaching values from 600 to 900 nits, allowing the user to experience a great juiciness of the image. Such results allow the user to feel the difference between HDR and SDR quality. Unfortunately, problems arise in situations where small light effects occur against a dark background. In such cases (e.g. test pattern 4 from the film Sicario 2), a noticeable drop in brightness can be observed, caused by the large sizes of the dimming zones used here. This limitation, combined with the dimming algorithm, affects how the television handles small bright elements against a dark background. At that point, we may perceive an unwanted lack of brightness, and the HDR effect resembles that of SDR.

Against a backdrop of contrast and black, the brightness of the QNED86A and the overall HDR effect perform much better. This is a television that can achieve around 700 nits under the best conditions, so in terms of luminance 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 manages well with their backlighting, and the details are quite visible. The problem arises when there are many dark tones. The lack of effective local dimming causes the black to practically disappear, and instead, we get a grey haze spreading across the entire screen. This kills the sense of depth and makes the image look flat, as if it lacks a cinematic character. In bright animations or colourful family films, this will not be a problem, as vibrant colours and bright light dominate. But in horrors or productions set in darkness, these limitations are very strongly felt. As a comfort, it is worth adding that the QNED86A is actually a QLED television with a PFS LED filter, which gives it very good coverage of a wide colour gamut. Both the DCI-P3 palette and the broader BT.2020 perform really well here. This makes the colours in HDR films saturated, juicy, and with the appropriate depth – even if the black itself disappoints, the colours can save the viewing experience and make the image look attractive.

In "Filmmaker" mode, which is the best choice out of the box, the Samsung Q80D TV shows solid colour reproduction. For SDR content, a visible drop at the beginning of the gamma curve suggests that details in dark scenes may be less pronounced, impacting the overall viewing experience. Regarding white balance in SDR content, while it is generally accurate, significant drops in blue colour when screen coverage exceeds 70% can result in less natural hues in bright and dark scenes. Users may notice that some blue elements in the image may appear less intense, and the overall colour will have a warmer tint.

In contrast, for HDR content, the EOTF curve being above the reference line for most of the time indicates that the TV may struggle with accurately reproducing brightness and details in the brighter areas of the image, which may be disadvantageous for the viewer. It is also worth noting the substantial drop at the beginning of this graph, indicating that the TV has difficulties reproducing brightness in the darker areas of the image, as seen in the contrast and black tests, where several scenes were unable to showcase the full capabilities of the TV's brightness. In terms of its white balance, the initially good results on the graph are promising, but the sharp drop in red colour, which significantly falls down, combined with a large increase in blue colour, may lead to inaccuracies in reproducing certain skin tones and other key colours. This phenomenon may be noticeable to viewers in scenes where colour details are crucial.

We primarily tested the QNED86A in Filmmaker mode, which is designed to provide the most faithful picture. Unfortunately, right out of the box, there were quite a few shortcomings. The most noticeable was the poorly tuned white balance – there was a lack of blue, causing the overall image to take on a slightly yellowish, and at times even orange hue. An even bigger problem turned out to be the way the television manages brightness. Due to its technical limitations – specifically, local dimming that only works along the edges of the screen – the QNED86A tends to oversaturate entire scenes. This is where the flattening effect we mentioned earlier comes from. Instead of clear depth and contrast, we get something akin to “boosted brightness,” which can strain the eyes over time.

The film mode after calibration looks significantly better than the one you can see when taken out of the box. Samsung offers an advanced range of calibration tools in its televisions. Among them are 2- and 20-point greyscale adjustment and CMS (Colour Management System). Both in HDR and SDR mode, the white balance has improved significantly, although there are minor errors at the end of the graph in the case of HDR content. The contrast has also been greatly improved, and the gamma curve responsible for SDR shows better results. However, when it comes to HDR, the EOTF curve in the television seems to be at an ideal level at first glance. Yet, when we delve deeper and enable the EOTF graph while watching films, we may notice that all the lines of the curve are above the reference line. One could even say that the television is "cheating" when playing film materials. Such a situation, where the EOTF curve is above the reference line, makes the screen – although it may seem brighter, which some users may find attractive – lose detail in the darker parts of the image. In practice, this means that in scenes with a lot of shadows or dark elements, the television is unable to accurately render the details that should be visible.

What has been saved in the QNED86A6A is undoubtedly the colours. After calibration, the white balance was set with great precision, ensuring that deviations on the Colour Checker palette mostly did not exceed the visibility threshold for the human eye. In other words – the hues finally looked natural, without the strange yellow or orange tones that previously spoiled the perception. Unfortunately, even the best calibration cannot circumvent the structural limitations. The already very modest number of local dimming zones and their unfortunate placement mean that the analysis of the EOTF curve in films still showed clear over-brightening of scenes. The picture tended to flatten, lacking cinematic depth. Fortunately, this effect is not so noticeable in older productions or in SDR content. There, the calibration truly makes a difference and allows one to harness the QNED so that the image can be appealing. However, the specifics of this construction – especially the issues with contrast – cannot be completely bypassed.

Samsung Q80D performs very well with low-quality materials. The noise reduction works on the principle of gentle grading, making it very effective in smoothing out unwanted image disturbances. Unfortunately, this same effectiveness also causes elements that should not be smoothed, such as film grain, to become blurred. For those who value a pliable, smoothed image more, this can be seen as a significant advantage, especially for lower-quality content.

When it comes to image scaling, Samsung Q80D stands out positively in this aspect, significantly enhancing viewing comfort. The television handles the conversion of lower-resolution materials well, improving their quality and detail. For example, in the attached image with the model, there are no visible artifacts or excessive fraying of branches, which attests to the advanced image processing technology.

If someone is worried about potential "steps" when blending colours, there is a simple way in the QNED86A to address this. Just activate the feature called Smooth Gradation and set it to a medium level. Then the television really smooths out all those unwanted transitions quite well – especially in older productions – and it does so in a way that film grain doesn't disappear, nor do strange artefacts appear. In other words, it can be used without concern.

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

The Samsung Q80D television stands out very positively in terms of motion fluidity and motion blur reduction, primarily due to the applied 120Hz panel and above-average response time of the panel. Users have two options for adjusting fluidity: "Motion Smoothing," which allows for adjustment of smoothness on a 10-point scale, and "Blur Reduction," particularly effective at higher refresh rates, improving the sharpness of rapidly moving objects. In the UFO test, no motion blur is visible behind the moving object, and the image is not cloned forward, indicating a lack of overshoot effect.

The QNED86A is equipped with a panel boasting a refresh rate of 120 Hz, so it can be said from the outset that it is suitable for both sports and gaming. And indeed, it is – the image appears smooth, and motion blur is not particularly intrusive. IPS panels have always had some issues with this, and here too, slight blurring can sometimes be noticed, especially in very dynamic scenes, but it is not something that ruins the viewing of a match or a fast-paced game. For cinema and sports fans, LG has included the traditional TruMotion smoothness enhancer. In the menu, we have two sliders – one for movies (De-Judder) and the other for sports (De-Blur). The first adds missing frames and can be adjusted to modify the character of motion – from raw, cinematic to a smoother, more ‘theatrical’ look. The second improves sharpness during dynamic actions, so it's worth turning it up a bit if you watch a lot of sports.

The Samsung Q80D television is a true gem for gamers. It is equipped with four HDMI 2.1 ports, which is a rarity, especially in this price range. This allows users to enjoy features such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and 120Hz in 4K resolution. These features ensure smoothness and responsiveness of the image, which is a key aspect during dynamic gameplay. The television also supports HGIG (HDR Gaming Interest Group), enabling optimal display of HDR content in games. Additionally, it is equipped with a Game Bar that allows quick access to gaming settings. Users of Nvidia graphics cards will also be pleased thanks to the implementation of G-Sync. This feature eliminates stuttering and screen tearing. The only downside is the lack of support for Dolby Vision mode, which may be disappointing for users looking for this HDR format. It is also worth mentioning that since 2022, thanks to a partnership with Microsoft, Samsung televisions offer the Xbox Game Pass application, allowing for cloud gaming. This is an additional advantage for gamers who want to access a wide library of games without the need for a console.

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 run in full 4K at 120 Hz with support for all functions. This is a significant advantage, as some competitors still only offer two such ports, which can be troublesome with multiple devices. It also includes VRR, or variable refresh rate, which eliminates screen tearing, as well as ALLM, which automatically activates game mode when the console is turned on. Dolby Vision Gaming is also included, along with proper implementation of the HGiG format, so titles that support these formats look more vivid and detailed. On top of all this, there is the Game Optimizer – a sort of control centre for gamers. From this interface, you can view picture parameters in real-time, quickly change modes, activate additional features, or adjust image settings to your personal preferences. The LG QNED86A6A essentially has everything one could expect from a modern gaming television.
