LG QNED91T6A vs LG QNED86A / QNED85A / QNED87A

As befits a MiniLED television, LG QNED91T easily surpasses the magical barrier of 1000 nits on the luminance chart. In scenes where light played a key role, the effect was truly decent. For instance, 1000 nits in the first scene of "Life of Pi" is an impressive value, and the 600 nits achieved in the third and fifth scenes allowed one to feel the true magic of HDR. However, problems arise with very small light elements on the screen, such as the moon, street lamps, or lights. A value around 100 nits - to put it bluntly - is disappointing, as these elements are dark enough to be barely visible. The television deserves praise for covering 96% of the DCI-P3 colour gamut and 75% of BT.2020. LG QNED91T leaves us with very mixed feelings, mainly due to the very aggressive dimming algorithms, which, while effectively eliminating the halo effect, negatively impact the brightness of smaller elements.

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.

All our tests are conducted in the best picture mode on each television. In this case, as usual, it is the Filmmaker mode. The name of the mode suggests ideal colour reproduction; however, there were noticeable deviations from the correct image here. Our unit, in terms of white balance, displayed quite a strong dip in blue hues - both in SDR and 4K HDR content - which resulted in a distinct yellowing of the image, visible in comparison scenes from the film with Tom Cruise. As we mentioned earlier, QNED91T has certain tendencies to brighten the screen. This is confirmed by gamma, which is quite significantly below the reference value of 2.4. Meanwhile, the EOTF curve, responsible for brightness in 4K content, showed some issues with the television's dimming in the darkest areas, which we could observe in the paragraph describing the quality of the HDR effect. Although the Filmmaker mode is quite a good "out-of-the-box" mode, it too requires some adjustments.

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.

LG offers advanced calibration tools in its televisions such as 65QNED91T6A, which we utilised. When it comes to white balance, we were able to significantly correct it in SDR content. The picture mode in 4K HDR quality posed greater challenges, which, although still not perfect, looks significantly better than before calibration. Errors on the Color Checker palette and colour gamut are much smaller than in the factory settings. Regarding brightness characteristics, gamma for HD content is practically ideal, with a slight exception at the end of the graph. However, the television had the most trouble with brightness in 4K HDR content. Analyzing the EOTF characteristics in films, we observed that the television manipulates brightness quite heavily, which we could see in previous tests. Brightness is significantly boosted compared to the graph in the static test, and the television lights up certain scenes to the point that some smaller elements lose detail. This is unfortunately caused by the average backlight zone management algorithm in this model. Nevertheless, calibration yields quite good results, especially when it comes to the precise reproduction of colours.

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.

When it comes to tonal transitions in lower quality materials, the television offers a well-known feature from LG televisions - "Smooth Gradation". We can control it in three levels: low, medium, and high. We recommend using the medium option, as it does a good job of removing tonal transitions without causing noticeable problems with the removal of object structure or other artefacts.

As for image scaling (upscaling), LG's Alpha processor performs quite well in this regard. The image appears very plastic, with slight aliasing on some elements, which does not significantly affect the quality. It looks really okay, and the overall effect is very satisfactory.

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 television has a refresh rate of 120 Hz, which should satisfy most users in terms of motion smoothness. Additionally, QNED91T is equipped with the TruMotion feature, which allows for smoother image display in films. Within this feature, we can adjust the "De-Judder" and "De-Blur" sliders. The "De-Judder" slider is responsible for reducing judder in films, which is particularly useful when playing content with a lower frame rate, while "De-Blur" helps to reduce blur in fast scenes, which is important for sports or dynamic shots.

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 LG 65QNED91T6A television is equipped with HDMI 2.1 ports with full bandwidth of 48 Gb/s, providing full support for all the standards needed for gaming on modern consoles. We can count on variable refresh rate (VRR) support and automatic low latency mode (ALLM). This ensures smooth gameplay without delays.

Thanks to support for all popular HDR standards in games, such as HGiG and Dolby Vision, we can fully utilise the potential of the PS5 and XBOX One consoles. The television also handles lower resolutions than 4K without any issues, so even older consoles look good on it. The Game Bar makes it easy to access gaming-related settings, allowing us to quickly and intuitively adjust picture parameters and features for gamers. Additionally, the QNED91T offers the NVIDIA GeForce Now feature, which allows us to play in the cloud without needing a console. However, it should be noted that this solution is quite costly and somewhat falls short of the Xbox Game Pass, which is available only on Samsung televisions.

QNED91T LG is an excellent choice for both less experienced and more advanced gamers looking for a versatile television for gaming.

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.
