Samsung S90D / S94D 48" (WRGB OLED) vs LG QNED86A / QNED85A / QNED87A

In the tested film scenes, the television Samsung OLED 48 S90D achieves impressive brightness results, surpassing 800 nits in the first four shots, which can be considered a very good result. In the case of the final shot, where a fullscreen flash of sunlight is visible, the brightness drops to around 400 nits, but still remains at an acceptable level. However, it's worth noting that this model in larger sizes offers higher values, exceeding the "barrier" of 1000 nits. Additionally, speaking of the DCI-P3 colour space coverage at 97% is an excellent result, which guarantees extremely rich and realistic colour reproduction, further enhancing image quality. However, once again it should be remembered that the panel in the 65' variant equipped with a QD-OLED panel will be even better in this aspect. For those hesitating in choosing the size of the S90D model, it is worth mentioning that the larger versions of this television offer better HDR effects, and consequently, higher scores in our tests.

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.

The S90D Samsung television has been tested in Filmmaker mode, which offers good colour reproduction, although with some imperfections that may be noticeable to more demanding users. This mode can seem overly warm, and users switching from Standard mode may experience a slight shock. It's worth noting that this state of affairs is caused by poor settings, such as in the white balance, rather than the Filmmaker mode itself. In both SDR and HDR content, the device shows drops in blue, causing colours to become warmer than they should be. In practice, this means that some shades, such as sky blue or skin tones, may appear less natural and more tinged with pink or yellow. The Colour Checker test confirms these deviations, showing shifts towards warmer tones. In SDR content, the gamma graph indicates slight fluctuations, causing the image to be minimally darker, especially in shadows. This may affect less distinct details in darker scenes. Conversely, in 4K HDR materials, the EOTF curve is situated above the recommended line, leading to some parts of the image being displayed too brightly, which can cause clipping in the brightest areas. Overall, the Samsung S90D presents a solid image right out of the box, but for the best results, especially with more demanding content, additional calibration is recommended.

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.

After calibration, the television Samsung OLED 48 S90D in film mode looks even better than one could have presumed. The white balance, for both HD and 4K HDR content, has been improved to nearly perfection. Although minor errors can still be noticed, they are so minimal that they do not significantly affect the quality of the image. The colours are more balanced, which translates to a natural representation of details, particularly in scenes requiring a precise colour palette. It is worth adding that this model in the 48' size is equipped with a WOLED panel that has a different characteristic compared to larger sizes and has a smaller coverage of a wide colour gamut, not offering such rich colours as, for example, the 65-inch version, which is fitted with a QD-OLED panel.

The contrast has also undergone significant improvement. The gamma graph after calibration is much closer to the expected line, providing a better balance between the bright and dark parts of the image. The EOTF curve, which before calibration showed issues with overexposed scenes, now displays better results. This effect allows for greater detail preservation in the bright parts of the image, especially in HDR material.

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.

The Samsung OLED 48 S90D television performs very well in smoothing tonal transitions. Thanks to the applied technology, the transitions between colours are more fluid and natural. There is also the option to use the noise reduction function, which further smooths tonal transitions, which can be useful in certain situations. However, it is worth remembering that enabling noise reduction can also lead to the smoothing of desired film grain, which in turn can reduce the cinematic atmosphere of the image. For this reason, caution is advised when using this function, as it is better to leave the natural grain that adds character and authenticity to the content being viewed.

Samsung, as always, does not disappoint and excels at scaling images from lower resolutions. The S90D OLED 48 Samsung television effectively processes lower resolutions, as seen in the visible image. The outline of the model is clear and correct, looking natural and detailed as a result. Moreover, the branches of trees are well replicated, showing no strong jaggedness that could detract from the quality of the image. Thanks to effective scaling, even lower resolution materials look attractive on the screen, satisfying users who prefer a variety of content sources such as regular aerial/cable television.

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 S90D television is equipped with a 120 Hz panel, with the possibility of "overclocking" to 144 Hz with the appropriate PC configuration, ensuring exceptional motion fluidity. For years, Samsung has offered a variety of image sharpness settings on a ten-point scale, allowing users to customise the display to their preferences. In the UFO test, thanks to the use of an OLED panel, there is no sign of any blurring. The pixel response is instantaneous and perfectly captures dynamic movements. In this aspect, OLED technology is considered one of the best on the market. The image is incredibly sharp and detailed, even during fast action, making the S90D OLED 48 Samsung television an ideal choice for gamers and sports enthusiasts.

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 OLED 48 S90D television is excellently tailored to the needs of gamers, offering four HDMI 2.1 ports that support features such as Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR), and HGIG (HDR Gaming Interest Group). With these technologies, gamers can enjoy smoother gameplay and faster screen responsiveness, significantly enhancing comfort during long gaming sessions. Additionally, the Game Bar feature allows for easy adjustments of settings such as screen ratios, which can be particularly useful in various types of games. For PC users, the television offers an impressive refresh rate of 144Hz, and Nvidia and AMD graphics cards support G-Sync and FreeSync, further improving image fluidity. Although the lack of Dolby Vision support may be a downside, it is worth noting that this technology is not as widely used in games as it is in films. Nevertheless, the S90D still offers excellent features for gamers, making it an outstanding choice for those seeking high-quality visuals and advanced gaming technologies.

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.
