Samsung Neo QLED QN90D / QN92D vs Samsung Q6F (IPS)

During synthetic tests, Samsung QN92D showed its incredible capabilities in terms of brightness. The charts clearly indicate that the television can achieve an impressive 2000 nits, giving it a solid power base to compete with the best models on the market. Such a result places it at the forefront, especially in the context of displaying HDR content, where brightness plays a key role. However, what happens when we move the tests to real film scenes? In favourable conditions, such as the first scene from the movie Life of Pi or the last scene, where the image is completely flooded with light, Samsung QN92D can achieve almost laboratory results, impressing with its brightness. The situation looks different when small, bright objects appear on a dark background, as in the fourth scene from the movie Sicario. In such cases, the television doesn't perform as well – brightness drops several times, and maximum values in the best conditions are around 600 NITS. Similar to contrast, these limitations arise from the use of an aggressive local dimming algorithm. This algorithm aims to reduce the 'halo' effect around bright objects on a dark background, but often at the expense of overall brightness. As a result, while the television performs well in bright scenes, its ability to display full brightness is limited when it comes to small, vivid elements.

Unfortunately, the Samsung Q6F is a very dark model. Its peak brightness in HDR does not exceed 250 nits, which is definitely too low to even talk about any "high dynamic range" or HDR effect. In practice, it's better to stick to content in SDR format, which simply looks more predictable on this TV. Another issue is the global dimming technique – in scenes with a lot of black, the TV drastically dims the entire screen to artificially improve the black levels. This results in the image becoming even darker, with brightness sometimes dropping below 100 nits. The only consolation is the QLED technology, but even here it's average. The applied quantum dot layer is not of the highest quality, as the coverage of the DCI-P3 colour gamut does not exceed 90%. Because of this, colours in HDR content may simply appear unsaturated.

The best mode that reproduces colours best on the Samsung QN92D has consistently been the Filmmaker mode for years. While it generally offers decent colour quality, it is not free from significant issues. Let's start with the analysis of HD/SDR image quality. The biggest challenge here is the white balance – the graphs show considerable instability, with a clear dominance of red making the image too warm. This distortion causes hues to be unnaturally shifted towards warmer tones, which can negatively affect the perception of materials with natural colours. Contrast, based on the gamma chart, although not the worst, remains far from ideal, impacting the overall image quality, especially in darker scenes.

This issue also persists with 4K materials, such as series or films of higher quality. In this case, the white balance also turns out to be faulty, with noticeable deficiencies in blue and red colour, leading to tonal shifts. Tests using the Colour Checker tool confirm these problems – all colours tend to skew towards yellow shades, further distorting the natural appearance of the image. Although the Filmmaker mode is one of the best available modes for watching cinematic content, it still requires improvements, especially in terms of colour accuracy and white balance.

We tested the television in Filmmaker mode, which showed us two completely different sides of this model. Looking at SDR content, we were honestly shocked at how good this television looks straight out of the box. It was really hard to pick on anything here. Despite a slight 'messiness' in white balance and some slightly brightened details in the blacks (which directly stems from the IPS panel construction), colour errors hovered around the '2' level. This is not only a surprisingly good result but rather phenomenal, considering the price of the device.

On the other hand, what the Q6F showed in terms of colours when switched to HDR mode was a very unpleasant surprise. The errors in colour reproduction and palette were so massive that our charts literally ran out of scale. Of course, since Samsung even in such a budget model offers very extensive calibration options, we decided to approach the issue professionally and see what could be done during calibration.

After calibration, the Filmmaker mode on the Samsung QN92D television shows significant improvement, particularly in the SDR content range. The white balance has been greatly enhanced – the previous colour misalignment and dominance of red have been eliminated, resulting in a more natural colour reproduction. In terms of brightness, although the gamma chart did not require significant adjustments, it has been stabilised, which affects the overall picture quality.

Regarding high-quality materials, the white balance has also improved in this case. However, it is worth noting the contrast. The EOTF curve, which illustrates the values in this area, appears correct at first glance. However, upon closer inspection, the television struggles to maintain appropriate contrast in film materials. The EOTF curve reveals some discrepancies, suggesting that despite the progress, there are still areas that require improvement in this aspect. The television continues to strive for excellence in contrast reproduction. A strength of this television is the saturation of colours. Skin tones are rendered very well, and although some colours may be slightly oversaturated, the overall effect looks really attractive – the colours appear rich and vibrant.

Despite some shortcomings in contrast, after calibration, the Filmmaker mode on the Samsung QN92D offers excellent image quality, with natural colour reproduction, making it a great choice for watching movies.

After our calibration, the colours in SDR mode looked even better – the result is truly surprising, as colour errors at a level of "1" are something typically seen in devices costing several thousand dollars. In this respect, the Q6F is really a great screen for everyday television, less demanding series, or movies. Unfortunately, our intervention in HDR mode did not yield a noticeable improvement. The television, due to its weak blacks and low coverage of a wide colour gamut, still has significant issues with proper colour saturation, especially reds. This is an example of a device where HDR primarily exists as a label on the box – for everyday use, we definitely recommend watching content in SDR format.

Let's check how the Samsung QN92D TV performs with tonal transitions in very poor quality materials. The noise reduction feature shows good effectiveness, improving the fluidity of tonal transitions even in difficult conditions. However, it should be noted that, similar to other Samsung TVs, the effectiveness of this feature can lead to the removal of desirable elements, such as film grain, which can sometimes affect the authenticity of the image.

When it comes to digital processing, the Samsung QN92D TV also performs excellently. During tests, the image looked very good, with the model presented in a natural and correct way. Details, such as branches in the background, were reproduced with great precision, highlighting the TV's ability to enhance the quality of low-resolution materials.

Q6F handles upscaling lower resolution content to native 4K very well. The scaling is surprisingly good, even for such an inexpensive QLED model. The only downside is when watching very low-resolution materials like 576p (typical for old DVD players) – the image may appear slightly cropped. This is because the TV does not allow the option to turn off the Overscan feature, which is a common issue with Samsung devices.

The situation is completely different when it comes to digital processing, or the attempt to smooth the image of unwanted artifacts. Here, the TV completely fails. Although in the menu we find a feature called "Noise Reduction," it does not produce any noticeable results regardless of the slider setting. The only thing it seems to do is introduce undesirable errors into the image. Despite its presence in the system, we definitely do not recommend using it.

The Samsung QN92D television is equipped with a 144 Hz panel; however, when watching content using the smoothness feature, the maximum refresh rate is 120 Hz. As a result, both gamers and sports enthusiasts will be satisfied with the picture quality. It’s also worth mentioning the available options for image enhancement, such as the "motion blur and judder reduction" feature, which allows users to adjust smoothness to their individual preferences on a 10-point scale. Motion blur reduction increases the sharpness of fast-moving objects, while judder reduction smooths out motion, eliminating the "stutter" effect. With these advanced settings, one can achieve optimal visual experiences, making the Samsung QN92D perfect for both dynamic scenes and intense gaming.

In terms of motion blur, the television performs really well, and it’s hard to pick faults. The only note we might have is a slight overshoot effect noticeable on dark backgrounds during our test with "Ufoludkiem." Nevertheless, thanks to the advanced smoothness settings, the Samsung QN92D excels in both dynamic scenes and intense gaming.

The 60 Hz panel in the Samsung Q6F is standard in this price range, making it a rather average model for dynamic sports or gaming. However, when it comes to movies, the TV performs quite well thanks to its smoothing feature. The "Motion Vibration Reduction" option allows you to adjust the motion smoothness to your own preferences – from preserving a cinematic feel to full smoothness.

The television Samsung QN92/QN90 is an excellent choice for avid gamers, deserving of the highest recommendations. This model offers practically all the features available on the market in terms of gaming, making gameplay even more exciting. One of the key differentiators is the 120 Hz panel, which ensures exceptional motion smoothness, crucial during dynamic action games. The television also boasts low input lag, guaranteeing instant reactions to player commands. Additionally, technologies such as VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode) adjust the refresh rate and automatically switch the television to game mode, translating to even better gaming experiences. Another advantage is the Xbox app, which allows gaming of favourite titles directly on the television, eliminating the need for a console. This is a typical feature of Samsung televisions, making them exceptional in the gaming world.

Auto Motion Plus Game is a feature that really deserves praise for Samsung. It is a motion smoother that works wonderfully in games, creating the impression of a higher frame rate – a 30 frames per second image looks like 45, and 60 Hz becomes close to 90 Hz. Importantly, this feature does not introduce significant lag (input lag does not exceed 25 ms), so it does not negatively affect gameplay comfort, unlike many other smoothers available on the market. This allows gamers to enjoy a much smoother image without compromising responsiveness.

We won’t beat around the bush – the Q6F is not a television designed with gamers in mind. While it does include features like ALLM (Auto Low Latency Mode) and VRR frame syncing for consoles, that's pretty much where the list of advantages ends. Beyond these basics, the television offers nothing more that could satisfy those who spend a lot of time in front of a console. It's a real shame that a useful tool like Game Bar, which allows for quick control of game parameters in higher-end Samsung models, is missing here. In terms of gaming, this is an absolutely basic model and it will only suit 'casual' gamers.
