LG QNED91T6A vs SAMSUNG QN80F

As befits a MiniLED television, LG QNED91T easily exceeds the magical barrier of 1000 nits on the luminance chart. In scenes where light played a key role, the effect was truly commendable. For instance, 1000 nits in the first scene of "Life of Pi" is a really impressive value, and the achieved 600 nits in the third and fifth scenes allowed for a true sense of HDR magic. However, problems arise with very small light elements on the screen, such as the moon, street lamps, or lights. Values around 100 nits - to put it bluntly - are disappointing, as these elements are so dark they are 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 halo effect, do impact the brightness of smaller elements.

QN80F is quite a bright screen – in synthetic tests, it reached nearly 1000 nits, which allows for reasonable expectations of HDR content. And indeed, in many scenes, the TV can truly shine. Sequences with a lot of light – like shots from the movie Life of Pi or wide, bright surfaces in The Meg – look impressive. Brightness stays around 700 nits, which provides a solid effect, enough to feel the true "HDR magic." Unfortunately, not every scene looks this good. In content with small, bright details on a dark background, like in Sicario 2, the TV can struggle – it can significantly dim individual elements, sometimes to the point where they disappear from the image. This is a result of the limited number of dimming zones, forcing the device into compromises: either stick to inky blacks or sacrifice some detail. QN80F usually chooses the former. As a consolation, it offers quite decent coverage of a wide color palette – DCI-P3 at 93%. It's not the highest score on the market, but it's more than enough for most content on streaming platforms.

All our tests are conducted in the best picture mode on each television. In this case, as usual, it’s the Filmmaker mode. The name of the mode suggests ideal colour reproduction; however, there were noticeable deviations from the correct image. Our unit, in terms of white balance, exhibited a significant drop in blue hues - both in SDR and 4K HDR materials - resulting in a noticeable yellowing of the image, evident in the comparison scenes from a movie with Tom Cruise. As we described earlier, QNED91T has a tendency to brighten the screen. This is confirmed by the gamma, which is quite significantly lower than the reference value of 2.4. Meanwhile, the EOTF curve, which is responsible for brightness in 4K content, showed some issues with the television’s ability to dim the image in the darkest areas, which we could observe in the paragraph describing the quality of the HDR effect. Although the Filmmaker mode is a pretty good "out of the box" mode, it still requires some adjustments.

We always test TVs in the best available factory mode – for the Samsung QN80F, this is the Filmmaker mode, and indeed, it provides the settings closest to the creators' intentions. However, this doesn’t mean everything looks perfect. In SDR content, the biggest issue was an unbalanced white balance – slight deficiencies in green and a noticeable excess of red led to noticeable colour errors, and one could say the screen had a pinkish hue. This was clearly visible in the colour checker test, where colours “escaped” outside their target fields – to such an extent that a sensitive viewer's eye could catch it even without the help of a meter.

In HDR content, the white balance was much better, but another issue arose – brightness management. The EOTF curve caused an overly bright image most of the time, which affected the perception of contrast and made the screen slightly “flicker” during dynamic changes in light. We’ve already discussed this in the paragraphs about black levels and HDR. Fortunately, Samsung offers users plenty of options. The QN80F features a rich set of calibration options, including a 20-point white balance – which is why we decided to check what this TV is really capable of after a proper calibration.

LG offers advanced calibration tools in its televisions such as 65QNED91T6A, which we took advantage of. When it comes to white balance, we managed to significantly correct it in SDR content. The picture mode in 4K HDR quality posed greater challenges, which, while still not perfect, looks significantly better than before calibration. The errors on the Color Checker palette and the colour palette are much smaller than in the factory settings. In terms of brightness characteristics, gamma for HD content is practically perfect, with a small exception at the end of the graph. However, the biggest issues the television faced were with brightness in 4K HDR content. Analyzing the EOTF characteristics in films, we noticed that the television manipulates brightness quite a bit, which we could observe in previous tests. Brightness is significantly boosted compared to the graph in the static test, and the television brightens certain scenes to the extent that some smaller details lose definition. Unfortunately, this is caused by an average backlight zone management algorithm in this model. Nevertheless, the calibration yields quite good results, especially regarding accurate colour reproduction.

After conducting a thorough calibration, it was possible to bring most image parameters to a really good level. The white balance in both SDR and HDR presents itself almost perfectly – the image is natural, neutral, and free from the previously noticeable redness. Colours have gained depth, and the overall visual experience has become more pleasant and cohesive. It was also possible to partially manage brightness, which in the factory version could cause issues. The EOTF chart shows that the television performs much better with brightness after calibration – there is no longer excessive dimming of certain elements. In films, it can still be noticed that the QN80F has a tendency to slightly brighten the smallest bright details – this is already a consequence of the device's construction and the limited number of dimming zones. In short: not everything can be overcome, but what was possible has been improved. After calibration, the QN80F makes a really good impression, looking simply more mature and professional.

When it comes to tonal transitions in lower quality materials, the television offers a well-known feature from LG TVs - "Smooth Gradation". We can control it at three levels: low, medium, and high. We recommend using the medium option, as it handles tonal transitions well without causing noticeable issues with removing the structure of objects or other artifacts.

On the other hand, when it comes to image scaling (upscaling), LG's Alpha processor performs quite well here. The image appears very smooth, with slight jaggedness in some elements, but this does not significantly affect quality. It looks really good, and the overall effect is very satisfying.

If you notice strange colour transitions or unwanted artefacts while watching lower quality materials – for example from YouTube – it's worth checking the settings and enabling the noise reduction feature. In our opinion, the best setting is at the 'medium' level – it effectively smooths out problematic colour transitions without overly blurring the entire image. However, it's important to know one thing: this option tends to remove film grain. If someone values preserving that effect (e.g., in older films), it's better to simply turn it off – regardless of the level, the grain always disappears.

Regarding resolution scaling (also known as upscaling), Samsung – as usual – performs very well in this area. The QN80F doesn't quite match the top models costing tens of thousands, but for its price class, it performs impressively. Materials of very poor quality (e.g., from SD television or older video files) are noticeably improved and look surprisingly decent. The only noticeable downside is the typical Samsung issue with overscan – which is a slight cropping of the image edges at very low resolutions, such as 576p.

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

QN80F is truly a “fast” TV. The panel used offers a refresh rate of up to 144 Hz, which in practice means that the screen keeps up with the action – whether we’re watching a movie, playing games, or browsing dynamic content online. The image doesn’t stutter, isn’t overly blurred, and everything simply looks smooth and pleasing to the eye. Of course, the manufacturer hasn’t forgotten about cinema fans – in the settings, we find an option to adjust motion smoothness, allowing us to tailor the effect to our own preferences. You can leave a more “frame-y” look (for those who enjoy the classic film vibe) or crank up the smoothness to a higher level to achieve a theatrical smoothing effect. Importantly, the choice is ours. Watching movies and playing on the QN80F is just plain fun.

The LG 65QNED91T6A television is equipped with HDMI 2.1 ports with a 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 gaming, such as HGiG and Dolby Vision, we can fully utilise the potential of the PS5 and XBOX One consoles. The television also easily handles lower resolutions than 4K, so even older consoles look good on it. The Game Bar makes it easier to access gaming-related settings, allowing us to quickly and intuitively adjust picture parameters and features for gamers. Additionally, the QNED91T offers NVIDIA GeForce Now functionality, allowing us to play in the cloud without needing a console. However, it's important to keep in mind that this solution is quite costly and somewhat falls behind the Xbox Game Pass, which is available only on Samsung televisions.

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

Samsung QN80F is a TV that delivers on almost every front when it comes to gaming. We have a 144 Hz panel, four fully-fledged HDMI 2.1 ports, support for gamers in the form of variable refresh rate (VRR), auto low latency mode (ALLM), and even one of the best-designed game bars on the market. The cherry on top is the motion smoother, which – as the only one in the world – works in games without significantly increasing input lag. Sounds like an almost perfect TV for gamers? And indeed, it’s almost that.

As usual, Samsung does not support Dolby Vision in gaming, but that’s no surprise anymore. However, what is much more surprising is that... the HGIG feature has disappeared – which is a system that allows a console (e.g. PlayStation 5 or Xbox Series X) to precisely match HDR tone mapping to the capabilities of the TV. In the latest firmware update for the 2025 models, this option simply vanished. It looks more like a bug than a deliberate move, but it must be honestly noted that as of the writing of this review, the HGIG feature is simply absent.

And it’s this one missing feature that turns the QN80F from an almost perfect gaming TV into a “nearly” perfect device. It’s a pity – because everything else indicated that Samsung could once again set the bar very high in this generation.
