LG QNED91T6A vs SAMSUNG QN80F

As befits a MiniLED television, QNED91T LG easily exceeds the magic barrier of 1000 nits on the luminance chart. In scenes where light played a key role, the effect was truly decent. For example, 1000 nits in the first scene of "Life of Pi" is really an impressive value, and the 600 nits achieved in scenes three and five allowed us to feel the true magic of HDR. However, problems arise with very small light elements on the screen, such as the moon, lanterns, or lamps. A value of around 100 nits - to put it bluntly - is disappointing, as these elements are so dark that they are barely visible. It is worth praising the television for covering the DCI-P3 colour gamut at 96% and BT.2020 at 75%. LG QNED91T leaves us with mixed feelings, mainly due to very aggressive dimming algorithms, which, while effectively eliminating the halo effect, do impact the brightness of smaller elements.

QN80F is quite a bright screen – in synthetic tests, it achieved nearly 1000 nits, which allows for reasonable expectations with HDR content. And indeed, in many scenes, the television truly shines. Sequences with a lot of light – such as shots from the movie Life of Pi or wide, bright surfaces in The Meg – look spectacular. Brightness maintains around 700 nits, which provides a solid effect, sufficient to feel the true "HDR magic." Unfortunately, not every scene looks that good. In materials with small, bright details on a dark background, like in Sicario 2, the television has problems – it can dim certain elements significantly, sometimes to the point where they disappear from the image. This is the result of a limited number of dimming zones, which forces the device to make compromises: either stick to inky blacks or sacrifice some details. QN80F usually chooses the former. As a consolation, it has quite decent coverage of a wide color gamut – DCI-P3 at 93%. This is not the highest score on the market, but it is more than enough for most content on streaming platforms.

We conduct all our tests in the best picture mode on each TV. In this case, as usual, it is the Filmmaker mode. The name of the mode suggests perfect colour reproduction; however, there were noticeable deviations from the correct image. Our unit, in terms of white balance, showed a significant drop in shades of blue - both in SDR and 4K HDR material - which caused a clear yellowing of the image, noticeable in comparison scenes from the film with Tom Cruise. As we described earlier, QNED91T has some tendencies to brighten the screen. This is confirmed by the gamma, which is significantly lower than the reference value of 2.4. On the other hand, the EOTF curve, responsible for brightness in 4K content, showed some issues with the TV dimming the image in the darkest areas, which we could observe in the paragraph describing HDR effect quality. Although the Filmmaker mode is quite a decent "out of the box" mode, it still requires some adjustments.

We always test televisions in the best available factory mode – for the Samsung QN80F, this is the Filmmaker mode, and indeed, it offers the settings closest to the creators' intentions. However, this doesn't mean that everything looks perfect. In SDR content, the biggest issue turned out to be an unbalanced white balance – slight deficiencies in green and a noticeable excess of red led to noticeable color errors, and one could almost say there was a pinkish tint to the screen. This was clearly visible in the color checker test, where colors would "escape" their target fields – to the 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 problem emerged – brightness management. The EOTF curve caused an overly bright image most of the time, which could affect the perception of contrast and made the screen slightly "flicker" during dynamic light changes. We have already discussed this in the paragraphs about black and HDR. Fortunately, Samsung leaves the user with plenty of options. The QN80F offers a rich set of calibration options, including a 20-point white balance – that's why we decided to check what this television is really capable of after 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 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 better than before calibration. The errors on the Color Checker palette and the colour palette are much smaller than in factory settings. Regarding brightness characteristics, gamma for HD content is practically ideal, with a slight exception at the end of the graph. However, the biggest issues the television had were with brightness in 4K HDR content. Analyzing the EOTF characteristics in films, we noticed that the television manipulates brightness quite significantly, which we observed in earlier tests. Brightness is considerably boosted compared to the graph in the static test, and the television brightens certain scenes to the extent that some smaller elements lose detail. Unfortunately, this is caused by an average local dimming algorithm in this model. Nevertheless, calibration yields decent results, especially in terms of precise 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 appears nearly perfect – the image is natural, neutral, and free of the previously noticeable reddening. The colors have gained depth, and the overall visual reception has become more pleasant and cohesive. It was also possible to partially master brightness management, which in the factory version could be problematic. The EOTF chart shows that the television performs significantly better with brightness after calibration – there's no longer excessive dimming of certain elements. In films, it can still be observed that the QN80F has a tendency to slightly brighten the smallest, bright details – this is already a result of the device's construction and the limited number of dimming zones. In short: not everything can be overcome, but what could be improved has been addressed. After calibration, the QN80F makes a really good impression; it simply looks more mature and professional.

When it comes to tonal transitions in lower quality materials, the TV offers the already-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 effectively removes tonal transitions without causing noticeable issues with removing the structure of objects or other artefacts.

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

If, while watching lower-quality materials – for example from YouTube – we notice strange color transitions or unwanted artifacts, it’s worth checking the settings and enabling the noise reduction function. In our opinion, the best setting is at the "medium" level – it effectively smooths out problematic color transitions while not excessively blurring the entire image. However, one must know this: this option tends to remove film grain. If someone cares about preserving this effect (e.g., in older films), it’s better to just turn it off – regardless of the level, the grain always disappears.

When it comes to scaling resolution (i.e., the so-called upscaling), Samsung – as always – performs very well in this area. The QN80F may not compare to the top models worth several thousand, but for its price class, it really performs impressively. Very low-quality materials (e.g., from SD television or older video files) are noticeably improved and look surprisingly decent. The only noticeable drawback is the typical Samsung issue with overscan – that is, slightly cropping the edges of the image at very low resolutions, e.g., 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 the TruMotion feature, which allows for smoother image display in movies. As part of this feature, we can adjust the "De-Judder" and "De-Blur" sliders. The "De-Judder" slider is responsible for reducing jitter in movies, which is particularly useful when playing content with a lower frame rate, while "De-Blur" helps reduce blurriness in fast scenes, which is essential for sports or dynamic shots.

QN80F is truly a "fast" television. The applied panel 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 on the internet. The image doesn't tear, it doesn't excessively blur, and everything simply looks smooth and pleasant to the eye. Of course, the manufacturer hasn't forgotten about movie fans – in the settings, we find an option for motion smoothness adjustment, allowing us to tailor the effect to our personal preferences. You can leave a more "cinematic" look (for those who enjoy a classic film vibe) or crank up the smoothness to a higher level for a theatrical smoothing effect. Importantly, the choice is ours. Watching movies and playing on the QN80F is simply a joy.

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

With support for all popular HDR standards in games, such as HGiG and Dolby Vision, we can fully harness 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 easy 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, enabling us to game in the cloud without needing a console. However, it should be noted that this solution is quite expensive and somewhat falls short compared to Xbox Game Pass, which is available only on Samsung TVs.

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

The 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), automatic 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 – uniquely in the world – works in games without significantly increasing input lag. Sounds like almost the perfect TV for gamers? And indeed, it is almost that.

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

And it is precisely because of this one deficiency that the QN80F goes from being almost the perfect gaming TV to a "nearly" perfect device. It's a shame – because everything else indicated that Samsung could set the bar very high once again in this generation.
