Samsung QLED Q80D vs Samsung Q7F

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.

Unfortunately, the Samsung Q7F is not one of the bright televisions, and this directly affects the quality of HDR movies. The peak brightness of the panel is only about 250 nits, which is definitely too low to speak of true cinematic experiences. In practice, the image in HDR content does not differ significantly from classic SDR, making it hard to talk about any "wow effect" that usually accompanies us while watching such films. During testing movie scenes, the image simply looked dim, and brightness almost invariably hovered around the mentioned 250 nits. The worst performance was observed in shots with small, intensely glowing elements – the applied global dimming technique reacted very aggressively, dimming the entire screen to maintain the black effect. On the plus side, it is worth noting the presence of a QLED coating that expands the color palette. As a budget QLED model, the Q7F performs quite decently here: its DCI-P3 color coverage is about 93%, and BT.2020 reaches 70%. This means that colors, despite the low brightness, can look quite vivid and attractive.

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.

The factory color reproduction in the Samsung Q7F definitely isn't one of its strong points. In Filmmaker mode, which theoretically should be closest to neutral, the white balance issue is immediately noticeable. There's too much red on the screen, while blue is noticeably lacking. The effects of this are very easy to see – white, instead of being neutral, takes on warm, almost slightly orange tones. Over time, this makes the entire image look somewhat unnatural, and bright areas of the scene can seem unrealistic. The problems become even more apparent in HDR content. The graphs show that the TV has significant errors in the Color Checker palette, which translates to visible inaccuracies in the real image. In practice, this means that colors are not presented as they should be. The Q7F also heavily manipulates brightness; darker elements are overly boosted, causing them to lose their cinematic feel, while bright parts can appear dimmed. As a result, the image seems flattened, and instead of helping to bring out details, contrast only highlights its own limitations. This is particularly frustrating in HDR materials, as every detail matters there. In scenes where a subtle play of light and shadow should be felt, the Q7F either overdoes the brightening or, conversely, suppresses elements that were meant to draw the eye. This causes the image to lose its depth, and instead of cinematic realism, we get more of a simplification effect.

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 professional calibration, we managed to bring the Q7F in order – at least in terms of SDR content. The picture in this mode looks really good: the white balance has been set correctly, the colors appear natural, and errors in the color palette have dropped to values that are practically invisible to the eye. The gamma behaves excellently, and the only minor drawback is a slight brightening of smaller elements, which results from the lack of local dimming. For everyday TV watching or standard quality films, the Q7F performs surprisingly well.

It was much more difficult to tame HDR content. Despite adjusting the white balance, the television continues to manipulate brightness significantly, causing scenes to sometimes look unnatural – what was meant to be subtly darker can end up being overly brightened, and bright parts of the image sometimes appear dull. The final effect is better than in the factory settings, but it is evident that the design limitations of the Q7F do not allow for fully utilizing the potential of HDR materials.

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.

Upscaling and digital image processing in the Q7F is a bit of a sine wave. On one hand, we have really nice upscaling – weaker sources look better than one might expect. The image becomes clearer, sharper, and even older movies or terrestrial TV hold up well. Samsung has been strong in this area for years, and the Q7F confirms that. On the other hand… things start to get tricky. The TV has a problem with overscan – part of the image is simply cut off, and it looks rather unrefined. Additionally, we were let down by a feature called "noise reduction," which should improve the smoothness of tonal transitions in weaker materials. In other Samsungs, it works relatively well, but here it practically makes no difference – the banding in gradients remains. It's a bit disappointing because we could have expected more from a model that is aimed at users looking for a display for SDR content.

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.

Motion blur and motion fluidity in the Q7F is probably the most budget-conscious element of this TV. The 60 Hz panel is noticeable, with blur being quite evident, especially in dynamic scenes, and it's rather difficult to consider this model as equipment designed for watching sports or playing fast-paced games. In tests with the little green man, there was a long tail, and the ball in a football match would leave trails behind it.

On the plus side, the presence of motion smoothing is commendable. It really makes a difference in movies - especially since most materials are recorded at 24 frames. Here we can decide for ourselves whether we prefer a more "cinematic" image, with the slight jerkiness characteristic of cinema, or a smoother, more "television-like" one. This actually works quite well and helps improve the viewing comfort for series or movies.

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.

Features for gamers in the Samsung Q7F is a topic that evokes quite a mix of emotions. On one hand, no reasonable person expected miracles here, as this is a 60 Hz television, and it was clear from the start that it wouldn't be equipment for extracting the maximum from consoles or PCs. On the other hand, since the manufacturer promised specific solutions in promotional materials, it is natural that we wanted to see them in practice. At the outset, it’s quite decent. The automatic game mode (ALLM) works, so you don’t have to manually fiddle with the settings, the console itself switches the television to low-latency mode. In addition, we have Game Bar, which looks impressive and allows you to view some basic parameters without leaving the game. And this is where the good news ends.

[UPDATE] We have updated our tests of Samsung televisions from the 2025 model year due to the release of software version 1131, which restored the key feature for gamers, HGiG.

The biggest problem with the Q7F is VRR, or rather its absence. Indeed, a relevant icon appears in the menu, and you can even see it in the Game Bar, but throughout the entire test, the feature remained inactive and could not be activated in any way. It’s even more disappointing regarding HGiG; this option was actually available at the beginning, but after the software update, it completely disappeared, which is just unprofessional. Therefore, the Q7F is suitable only for absolute basics. Sure, you can turn on the console, play calmer titles, and enjoy low input lag, but if someone is counting on more advanced features that the manufacturer promised, they will be disappointed. This is not a television that you buy with gaming in mind, and it’s better to be aware of that before making a purchase.
