Samsung S85F OLED vs Samsung Q6F (IPS)

As an OLED, the Samsung S85F can shine – literally. In favourable conditions, it can generate brightness exceeding 750 nits. This is significant because most films are created with displays aiming for around 1000 nits. In practice, this means that in scenes with moderately large, bright elements, the picture can look absolutely stunning. However, it's not always so rosy. When an enormous amount of light appears on the screen – whether it's an expansive, bright background or an entire frame filled with white – the S85F must tone it down. Brightness can drop by even four times in such scenes. This limitation is well-known to anyone familiar with OLEDs in this price segment, so we don't view it as a particular fail. However, something that deserves praise is what sets this model apart from the competition – colour gamut coverage. Thanks to the QD-OLED panel, our colour meter indicated values exceeding 100% coverage of DCI-P3 and an impressive 86% for the ultra-wide BT.2020 palette. Such results are hard to find even in televisions that cost several times more.

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.

Samsung, as befits a manufacturer with ambitions, has equipped the S85F with a mode called Filmmaker. Its task is simple: to make the colours on the newly purchased television as faithful as possible to what the director intended to show us. Sounds great… but, as is often the case, a theory that sounds wonderful doesn’t always translate into perfect practice.

In the tested unit, it quickly became apparent that the image – due to an excess of blue and red – looked as if someone had gone a bit overboard with the saturation. As a result, there were quite significant colour errors, particularly in 4K content. On top of that, there was an issue with brightness – the S85F could brighten most scenes more than it should, stripping them of the intended mood.

Fortunately, Samsung televisions, including the S85F, offer an impressive number of settings for advanced calibrators. This means that we could see what this panel is really capable of when it gets into the right hands.

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.

Thanks to the huge number of settings in the menu, we managed to bring the S85F almost to perfection. White balance in SDR content? Literally perfect – deviations do not exceed a value of "1". So we can confidently say that in materials with not too high dynamics, we have an image that's close to reference.

In HDR content, minor issues appeared, but they don't have much significance in practice – most errors fall below the threshold of perception, which is a value of "3". We also managed to tame the S85F when it comes to brightness management – the EOTF curve, even in films, holds nearly perfect straight line. This is one of those cases where after calibration, you can comfortably forget about the settings and simply watch movies and series at the highest level.

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.

The tone transition smoothing function in the S85F works really effectively – it can completely eliminate the problem of visible banding in very poor quality material, such as from YouTube. Unfortunately, even the lowest level of this option comes with compromises. The noise reduction is so aggressive that it can smooth out film grain, which many of us consider to be an element of the cinematic atmosphere. At the “Standard” level, we didn’t notice this function removing anything significant from the image, so we can recommend this setting. On the other hand, the “High” level is a different story – it can smooth out not just noise, but also small, desirable details like, for example, the texture of objects.

When it comes to image scaling, the S85F performs very well. The material looks sharp, and the only slight imperfection is the barely noticeable aliasing of edges. And there’s the ongoing issue with Samsung televisions – overscan. This can cause some scenes to be slightly cropped, which is worth noting when watching very old content.

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.

S85F is an incredibly fast television – and that’s not just empty hype. Thanks to the 120 Hz OLED panel, dynamic scenes, whether in games or while watching a live match, look just as they should – smooth, sharp, and without the feeling that something is "slipping" out of frame. The lightning-fast pixel response time, typical of OLEDs, plays a big role here. Transitions between frames are virtually instantaneous, and the image remains clear even during the fastest camera movements. A ball flying across half the field? A car speeding in a chase scene? Everything here is clear and free of the typical "trail" associated with LCDs.

This is exactly what we expect from a good OLED – zero compromises when it comes to motion smoothness. The S85F gives the impression that regardless of the pace of action, we can focus on what’s happening on the screen, rather than on the imperfections of the image.

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.

[UPDATE] We have updated our 2025 Samsung TV reviews following the release of firmware version 1131, which officially restores the essential HGiG (HDR Gaming Interest Group) support.

S85F has practically everything on board to become the dream screen for gaming. Four full HDMI 2.1 ports with a bandwidth of 48 Gb/s, support for VRR, ALLM, a super-detailed Game Bar that clearly shows all parameters – plus a gem in the form of Game Motion Plus. This motion smoother makes animation in games more enjoyable, while input lag increases slightly. It's a rare combination, and that’s a big plus for Samsung. Perhaps Samsung will fix this in the next update – and we have high hopes for that. Because if HGiG comes back, the S85F will become nearly the perfect TV for gamers.

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.
