Samsung S85D vs Samsung QN80F

Brightness is a key parameter in televisions, and the S85D Samsung model offers levels comparable to other OLEDs from a few years ago. Although it does not impress in this regard, its enormous advantage is the very competitive price. A peak brightness of 600 nits ensures good image quality in HDR conditions, giving users a taste of cinematic experiences in the comfort of their home. However, as with many budget OLED models, the biggest issue is very bright, full-screen scenes – in such moments, like the final scene from the film “The Meg,” the television can lose even half of its brightness, which is noticeable compared to more expensive OLED models. Despite this, the television offers impressive coverage of the DCI-P3 colour palette at 99%, allowing for vibrant and accurate colours to be displayed.

QN80F is quite a bright screen – in synthetic tests, it achieved nearly 1000 nits, which allows for justified expectations regarding HDR content. And indeed, in many scenes, the television can truly shine. Sequences with a lot of light – like shots from the film Life of Pi or wide, bright surfaces in The Meg – look impressive. Brightness remains 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, such as in Sicario 2, the television has issues – it can significantly dim certain elements, 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 maintain inky blacks or sacrifice some detail. QN80F usually chooses the former. As a consolation, there is quite decent coverage of a wide colour gamut – DCI-P3 at 93%. This is not the highest score on the market, but it is more than adequate for most content on streaming platforms.

The Filmmaker mode on the Samsung S85D does offer quite good factory settings, but it is not free from errors, particularly evident in colour reproduction. The white balance chart for HD and HDR content shows clear issues – both red and blue colours are significantly weakened, leading to a dominance of green. The result is an unnatural yellowish hue that can affect the perception of realistic scenes. The Color Checker test clearly shows that the colour samples deviate from expected values – for HD material, the colours can be overly saturated, with a noticeable shift towards green, which is also evident in the white balance chart. Conversely, for 4K HDR content, the colours appear too dull, lacking depth, making the image less appealing and natural. This effect is particularly noticeable in delicate scenes where colour precision plays a key role, which can be disappointing for discerning viewers who expect faithful reproduction of details and colour intensity.

As for brightness, the gamma chart for HD content looks quite good; however, there is a noticeable jump at the end, exceeding a value of 2.4. While this is not a major issue in most scenes, in more demanding sequences it may affect the clarity of bright details. For 4K content, the EOTF curve, responsible for delivering brightness, turns out to be problematic. The initial part of the chart shows a small jump. This phenomenon can result in excessive boosting of brightness in the brightest areas of the image, leading to loss of detail in very bright scenes.

Although Samsung S85D offers quite decent factory settings, especially in Filmmaker mode, it is worth considering manual adjustment of settings to improve some imperfections, particularly in colour reproduction.

We test televisions always in the best available factory mode – in the case of the Samsung QN80F, this is the Filmmaker mode, and indeed, it is this mode that offers settings closest to the creators' intentions. However, this does not mean that everything looks perfect. In SDR content, the biggest problem turned out to be an unbalanced white balance – slight deficiencies in green and a noticeable excess of red led to discernible colour errors, one could even say a pinkish tint on the screen. This was well demonstrated in the colour checker test, where the colours 'escaped' beyond their target fields – to the extent that even a sensitive viewer's eye could catch this without the aid of a meter.

In HDR content, the white balance was much better, but another issue arose – brightness management. The EOTF curve resulted in an overly bright image for most of the time, which could affect the perception of contrast and caused the screen to subtly 'flicker' during dynamic light changes. We have already written more about this in the paragraphs on black levels 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 – therefore, we decided to check what this television is really capable of after proper calibration.

After calibration, the Filmmaker mode on the Samsung S85D truly impressed. The white balance, regardless of the type of content, has significantly improved, resulting in more natural colours. The Color Checker test shows that colour reproduction errors are now minimal and rarely exceed acceptable values, which indicates accurate colour rendering. The factory colour reproduction left much to be desired, but the situation has now significantly improved – the colours are natural, precise, and look as if they were rendered exactly according to the creators' intentions. This is a huge step forward compared to previous generations, where colours were often distorted or too intense.

The brightness characteristics also benefited from the calibration – it is now more vivid and precise. The gamma, although fairly good previously, has become even more stable, providing a deeper, more natural image. The EOTF curve has been aligned, allowing details in dark areas to be more visible and the contrast more balanced. With all these improvements, the television delivers an image close to reference quality, greatly enhancing the enjoyment of watching films and HDR content.

After conducting a thorough calibration, it was possible to bring most of the image parameters to a really good level. The white balance in both SDR and HDR is nearly perfect – the picture is natural, neutral and devoid of the previously noticeable redness. The colours have gained depth, and the overall visual reception has become more pleasant and cohesive. It was also possible to partially master the 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 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, light details – however, this is the effect of the device's design and the limited number of dimming zones. In short: not everything can be overcome, but what could be has been improved. After calibration, the QN80F makes a really good impression; it simply looks more mature and professional.

Samsung S85D performs excellently in scaling images and smoothing tonal transitions. Like in other Samsung models, the television offers three noise reduction modes: off, standard, and high. Although it effectively improves gradations, it unfortunately also removes film grain, which many viewers desire to give the image a cinematic character. This grain often adds authenticity and a certain rawness to films, which is lost after smoothing. Removing the grain can make the image look too sterile and smooth, which detracts from the charm of the original film material. When it comes to scaling images, the Samsung S85D handles lower resolution content beautifully – the model in the picture and the branches in the background were displayed correctly, with no major issues with edge aliasing. The only noticeable drawback is the presence of overscan, which can sometimes cut off parts of the image, which may not please everyone.

If, while watching lower quality materials – for example from YouTube – we notice strange colour transitions or unwanted artefacts, it's worth checking the settings and turning on the noise reduction feature. In our opinion, the best setting is at “medium” – it effectively smooths out problematic colour transitions while not blurring the entire image too much. 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 simply turn it off – regardless of the level, the grain always disappears.

When it comes to resolution scaling (or so-called upscaling), Samsung – as usual – performs very well in this area. The QN80F may not compete with top models costing tens of thousands, but for its price class, it really does impress. Materials of very low quality (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, slight cropping of the image edges in very low resolutions, e.g. 576p.

As befits an OLED television, Samsung S85D offers excellent motion fluidity. Equipped with a 120 Hz panel and fast response time, the television provides very smooth playback of dynamic scenes without visible ghosting. For movie enthusiasts, there is a feature called "Image Clarity Settings," which allows adjusting the fluidity of the image to individual preferences on a 10-point scale. Motion blur reduction enhances the sharpness of rapidly moving objects, while motion smoothing smooths out movement, eliminating the "judder" effect. This way, every user can set the appropriate level of clarity that best suits their taste, from a more cinematic effect to sharper, smoother movements.

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 film, playing games, or browsing dynamic content online. The image doesn’t stutter, isn’t excessively smeared, and overall looks simply smooth and pleasing to the eye. Of course, the manufacturer hasn’t forgotten about cinema fans – in the settings, we’ll find an option to adjust motion smoothness, allowing us to tailor the effect to our personal preferences. We can maintain a more "framey" appearance (for those who enjoy the classic cinematic vibe) or ramp up the smoothness to a higher level for a theatrical smoothing effect. Importantly, the choice is ours. Watching films and playing on the QN80F is simply a delight.

Samsung S85D OLED is an excellent choice for gamers, thanks to its many modern features that facilitate and enhance gameplay. The television has four full-bandwidth HDMI 2.1 ports, allowing you to connect the latest consoles without worrying about image quality or frame rate limitations. This means support for 4K resolution at 120 Hz, which is ideal for modern titles. Additionally, the Samsung S85D has an ALLM (Auto Low Latency Mode) feature that automatically activates low latency mode when it detects a gaming device. This means you don’t have to manually switch settings – the television takes care of ensuring a fast response time, which is crucial in games where every second counts.

The VRR (Variable Refresh Rate) feature and G-Sync support are additional elements that make gameplay smoother. VRR adjusts the refresh rate to the number of frames generated by the console or computer, eliminating screen tearing and stuttering. This is particularly useful in dynamic games where the frame rate can fluctuate. Auto Motion Plus Game is a feature that Samsung has introduced with gamers in mind, and it is worth appreciating. With it, the image in games becomes smoother – 30 frames per second look like 45, and 60 Hz gains in fluidity, creating an effect close to 90 Hz. At the same time, there is no significant increase in input lag, which remains below 25 ms, making this feature stand out among others available on the market. Gamers can enjoy a smoother image without worrying about a decline in responsiveness.

Samsung has also ensured something extra – the television has a built-in Xbox Game Pass app, which means you can play in the cloud without needing to own a console. This is a great solution for those who want to enjoy gaming without investing in additional hardware. All you need is internet access, and you have a huge library of games at your fingertips. This makes Samsung S85D a fantastic choice for both casual gamers and those who are more advanced.

The Samsung QN80F is a television that delivers on almost every front when it comes to gaming. We have a 144 Hz panel, four full-fledged HDMI 2.1 ports, support for gamers in the form of variable refresh rate (VRR), automatic game 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 an almost perfect television 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, it is considerably more surprising that... the HGIG function 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 television’s capabilities. In the latest firmware update for the 2025 models, this option has simply vanished. This looks more like a mistake than a deliberate move, but it must be noted fairly that as of the date of writing this review, the HGIG function is simply not available.

And it is precisely because of this one missing feature that the QN80F transforms from an almost perfect gaming television into a “nearly” perfect device. It’s a shame – because everything else suggested that Samsung could once again set the bar very high in this generation.
