Samsung Neo QLED QN85D / QNX1D vs Samsung Q6F (IPS)

Samsung QN85D leaves us with mixed feelings regarding HDR quality. It can shine in synthetic brightness tests, achieving up to 1000 nits – which makes scenes like those from the film 'The Meg' or the beginning of 'Life of Pi', where the screen is entirely bright, look truly impressive. However, in practice, the device has its limitations – especially when smaller bright elements appear on the screen. In such moments, brightness noticeably drops, and the HDR effect loses its impact. At brightness levels around 200-300 nits, the magic of HDR simply fades away, failing to deliver spectacular effects. However, it's not the case that the television completely disappoints – a DCI-P3 colour gamut coverage of 95% is quite decent, although it does not stand out against the best competitors. Colours are well-reproduced, but it's clear that HDR could make a bigger impression if brightness were better controlled.

The Samsung Q6F is, unfortunately, a very dark model. Its peak brightness in HDR does not exceed 250 nits, which is a value that is decidedly too low to even talk about any effect of “high dynamic range,” or HDR. In practice, it’s better to stick to content in SDR format, which simply looks more predictable on this television. Another problem is the global dimming technique – in scenes with a lot of black, the television drastically dims the entire panel to artificially improve the black levels. This causes the image to become even darker, and the brightness can drop below 100 nits. The only consolation is supposed to be the QLED technology, but even here it is average. The layer of quantum dots used is not of the highest quality, as the coverage of the DCI-P3 colour palette does not exceed 90%. As a result, the colours in HDR content may simply appear under-saturated.

Samsung QN85D TV has been tested in the best available mode – Filmmaker. Although one might expect that its name suggests a mode perfectly tailored for films, it unfortunately has several significant issues.

In terms of white balance for HD content, there is a clear dominance of red and blue, which causes the entire image to take on a pinkish hue – this is also confirmed by Colour Checker tests. This effect disrupts the naturalness of skin tones and many other elements, particularly noticeable in more challenging scenes. Initially, the white balance for 4K HDR content seems correct, but at the end of the graph, there is a significant spike in blue shades, which impacts the final image quality, making the colours appear unnatural.

The gamma brightness characteristics are also not ideal – although it generally stays close to the reference values, there is a slight drop below the 2.4 level, which can affect the perceived depth of shadows. The EOTF curve responsible for 4K content does not present itself any better. There is a noticeable boost relative to the reference curve, which leads to excessive brightening of the image in some areas, thereby losing the cinematic quality that the Filmmaker mode should provide. Although it might initially seem that the effect is cinematic, unfortunately, the number of errors in colour and brightness reproduction is too significant to call it flawless.

We tested the television in Filmmaker mode, which showed us two completely different facets of this model. Looking at SDR content, we were genuinely shocked at how good this television looks straight out of the box. It was really difficult to find fault with anything here. Despite a slight 'muddiness' in the white balance or somewhat brightened details in the blacks (which directly stem from the design of the IPS panel), the colour errors hovered around a level of '2'. This result is not only surprisingly good but downright amazing, considering the price of this device.

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

After professional calibration of the Filmmaker mode on the Samsung QN85D television, a significant improvement is noticeable, especially for HD/SDR content. The white balance has been completely stripped of serious errors, and the brightness characteristics for this type of content have been significantly adjusted, allowing for a more natural and realistic image. Television, YouTube movies, and other HD materials now look much better, with appropriately balanced colours and without the excessive hues that previously spoiled the viewing experience.

However, the biggest issues concern 4K HDR content. Despite the calibration, it's difficult to speak of a serious improvement in white balance – the differences are cosmetic rather than crucial. Brightness, which is governed by the EOTF curve, appears to be set in line with the reference level in synthetic tests at first glance, but has its limitations during actual usage in films. When we analyse the EOTF curve in real film scenes, it becomes apparent how the television struggles to maintain brightness consistency. The effect is that mixed scenes still have lifted darkest elements, leading to exaggerated contrasts, while completely dark scenes remain too dark, negatively affecting the visibility of details.

After our calibration, the colours in SDR mode looked even better – the result is truly surprising, as colour errors at the '1' level are something generally seen in devices costing several thousand pounds. In this regard, the Q6F is really an excellent screen for everyday television, less demanding series or films. Unfortunately, our intervention in the HDR mode did not bring a noticeable improvement. The television, due to its poor 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 exists mainly as a label on the box – for everyday use, we definitely recommend watching content in SDR format.

When checking the smoothness of tonal transitions in low-resolution materials on the Samsung QN85D television, it is worth noting the noise reduction feature, which significantly improves problematic tonal transitions. On the other hand, this feature also has its downsides – it removes film grain, which is an important element of many productions, giving them authenticity, and it can also soften the image. This may appeal to those who prefer a more smoothed image; however, for lovers of the authentic look of films, using this feature should be considered carefully.

As for image scaling, the television performs very well. The model's figure is presented correctly, without noticeable distortions, and the branches in the background do not have excessive artificial sharpness, which is often a problem when scaling lower resolution materials. You can see the high capabilities of the image processor, which can effectively process lower quality materials, ensuring good final quality.

Q6F performs very well in upscaling lower-resolution content to native 4K. The scaling here is surprisingly good, even for such an inexpensive television from the QLED series. The only downside is the situation where we are watching very low-resolution materials, such as 576p (typical for old DVD players) – in which case the image may be slightly cropped. This is due to the fact that the television does not allow the Overscan function to be turned off, which is a typical issue with Samsung devices.

The situation is completely different when it comes to digital processing, specifically the attempt to smooth the image of unwanted artifacts. Here the television completely fails. Although there is a function in the menu called "Noise Reduction," it yields no visible results regardless of the slider setting. The only thing it manages to do is introduce undesired errors in the image. Despite its presence in the system, we definitely do not recommend using it.

Samsung QN85D TV is equipped with a 120 Hz refresh rate panel, which should satisfy both gamers and sports fans by providing a smooth and dynamic picture. There are options to enhance fluidity, such as the motion blur and judder reduction feature, which allows for precise adjustment of motion smoothness on a 10-point scale. Motion blur reduction increases the sharpness of fast-moving objects, making action scenes clearer, while judder reduction smooths movement, eliminating the "stuttering" effect. Smearing is generally well controlled, although there are occasional minor shortcomings that may be visible in more demanding scenes, particularly when an object moves against a dark background. Additionally, the TV offers a BFI (Black Frame Insertion) feature at 60 Hz, which can significantly improve the experience of motion fluidity, although at the cost of image flicker, which may be bothersome to some users.

The 60 Hz panel in the Samsung Q6F is standard for this price range, making it rather average for dynamic sports or gaming. However, when it comes to films, the television performs quite well thanks to the motion smoothing feature. The "Motion Reduction" option allows you to adjust the smoothness of movement to your own preferences – from maintaining a cinematic character to complete fluidity.

The Samsung QN85D television is an excellent choice for gamers, offering a wide range of features that enhance the gaming experience and make it even more exciting. With a refresh rate of 120 Hz, the image is incredibly smooth, which is crucial during dynamic scenes in action games. The television also features low input lag, ensuring that reactions to the player's commands are nearly instantaneous, translating to better control over the character and events on the screen.

In addition, the QN85D Samsung supports VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode) technologies, which optimise image fluidity and reduce delays by automatically adjusting the television to meet the needs of gamers. Furthermore, the Xbox app allows access to cloud gaming without the need for a console, which is a significant advantage for those who want to enjoy their favourite titles without additional hardware – a solution that sets Samsung televisions apart.

The Auto Motion Plus Game feature is another element worth highlighting. This motion smoother creates the impression of a higher frame rate – as a result, games running at 30 fps appear smoother, resembling gameplay at 45 fps, while games at 60 Hz come close to 90 Hz. Most importantly, this feature does not introduce significant lag, ensuring that the gaming experience remains undisturbed. This allows players to enjoy a smoother image without compromising on responsiveness.

We're not going to beat around the bush – the Q6F is not a television designed for gamers. Although it features additions like ALLM (automatic low latency mode) and VRR frame synchronisation for consoles, the list of advantages basically ends there. Aside from these basics, the television offers nothing more that would satisfy those who spend a lot of time in front of a console. It’s a great shame that such a useful tool as Game Bar, which allows for quick control of game parameters in Samsung's higher models, is missing here. In terms of gaming, this model is absolutely basic and is only suitable for "casual" gamers.
