Samsung QLED Q80D vs SAMSUNG QN80F

In the context of HDR, the Samsung Q80D television delivers impressive brightness performance in tested movie scenes, achieving levels between 600 to 900 nits when the frame is filled with light. This brightness enhances the vibrancy of the image and allows users to perceive the differences between HDR and SDR quality. However, challenges arise when small light effects appear against a dark background. For instance, in specific scenes, such as test slide 4 from Sicario 2, there is a noticeable drop in brightness due to the larger size of the dimming zones employed by the television. This limitation, coupled with the local dimming algorithm, affects the TV's ability to accurately display small bright elements on dark backgrounds, leading to a lack of brightness that can diminish the HDR effect, making it appear similar to SDR quality.

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.

In "Filmmaker" mode, which is considered the best out-of-the-box choice, the Samsung Q80D demonstrates solid colour reproduction. However, when viewing SDR content, there is a visible drop at the beginning of the gamma curve, suggesting that details in dark scenes may be less clear, which could detract from the overall viewing experience. While the white balance in SDR content is generally accurate, significant drops in blue at screen coverage above 70% can lead to less natural hues in both bright and dark scenes. Users might notice that some blue elements appear less intense, resulting in a warmer tint to the colour presentation.

For HDR content, the EOTF (Electro-Optical Transfer Function) curve being above the reference line most of the time indicates that the TV may struggle to accurately reproduce brightness and detail in the brighter areas of the image, which can be less than ideal for viewers. Additionally, there is a notable drop at the beginning of this graph, signifying the TV's difficulty in reproducing brightness in dark areas; this limitation is apparent in contrast and black tests, where several scenes fail to showcase the TV's full brightness potential.

Regarding white balance, the initial performance on the chart is promising, however, a sharp drop in red, coupled with a significant rise in blue, may lead to inaccuracies in reproducing certain skin tones and other key colours. This issue can be particularly noticeable in scenes where colour details are essential, potentially affecting the viewer's overall experience.

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.

After calibration, the Samsung Q80D’s Movie mode offers a noticeable improvement over the out-of-the-box settings. Samsung provides an advanced suite of calibration tools, including 2- and 20-point grayscale adjustments as well as a CMS (Colour Management System), allowing for precise control over both SDR and HDR content. The calibration greatly enhances white balance, although minor errors remain in HDR content toward the end of the graph. Contrast has also improved, and the gamma curve for SDR content now aligns well with expected levels.

In HDR, the EOTF curve initially appears to sit ideally, however, closer examination reveals all lines are slightly above the reference line, a phenomenon that may be seen as the TV "enhancing" brightness for added appeal. This effect, however, comes at a cost: while the screen may appear brighter overall, it sacrifices detail in darker areas, leading to a loss of subtle textures in shadowed scenes. As a result, scenes with deep shadows or dark elements may lose some finer visual details that would enhance the viewing experience.

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.

Performing admirably with low-quality content, the Q80D’s noise reduction feature uses gentle gradation to smooth out unwanted image disturbances. However, this technique can also soften certain details, like film grain, that some viewers might prefer to retain. For those who appreciate a more polished and smoother image, particularly with lower-resolution material, this becomes a significant advantage.

In terms of image scaling, the Q80D stands out, enhancing both quality and detail for lower-resolution media. Advanced processing technology reduces artefacts and maintains clarity, as seen in the clean edges and absence of fraying in elements like branches during test scenes. This capability makes it an excellent option for viewers seeking an enhanced and comfortable viewing experience, even with less-than-ideal content quality.

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.

Motion smoothness and blur reduction are standout features on the Samsung Q80D TV, thanks to its 120Hz panel and impressive response time. Users have two customisation options to enhance smoothness: "Motion Blur Reduction," adjustable on a 10-step scale for refined control, and "Blur Reduction," which works particularly well at higher refresh rates, enhancing clarity in fast-moving scenes. In the UFO test, the panel performs without trailing or forward-cloning effects, indicating a lack of overshoot and delivering clear, sharp visuals during rapid motion.

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 Samsung Q80D is a fantastic choice for gamers, offering a range of advanced gaming features that are rare in this price category. Equipped with four HDMI 2.1 ports, it enables key functionalities like ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and 120Hz support at 4K resolution, ensuring smooth and responsive visuals, essential for fast-paced gaming. The TV also supports HGIG (HDR Gaming Interest Group) for optimal HDR display in games and includes a Game Bar for quick access to gaming settings. Gamers with Nvidia graphics cards will appreciate the G-Sync support that eliminates screen stuttering and tearing.

Although it lacks Dolby Vision support, which may disappoint those seeking that HDR format, Samsung has partnered with Microsoft since 2022 to provide the Xbox Game Pass app, enabling cloud gaming access to a wide library of games without a console.

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.
