TCL P7K / P79K vs Samsung Q7F

When evaluating the HDR effect, we must make it clear and without marketing embellishment: the P7K/P79K is not and was never meant to be a master in this field. The maximum peak brightness that this panel can generate is only around 300 nits. This is a borderline value, a sort of thin red line between what can be considered a barely satisfactory HDR signal and what is really not much different from standard dynamic range (SDR), unfortunately leaning towards the latter. Synthetic tests found brutal confirmation in reality – our measurements taken during movie screenings showed that luminance in key bright parts of the content rarely exceeded the threshold of 200-250 nits. Therefore, this is not a television that would allow content produced in a wide tonal range to truly shine, and we must openly acknowledge that.

Unfortunately, the issue of color reproduction is presented equally restrained. Although the manufacturer positions this model in the "QLED" family, thanks to the use of a PFS LED filter, the results do not match the heightened expectations. The coverage of the wide DCI-P3 color gamut is only 86%. Compared to the market, this is at best an average result, as most devices that employ additional layers to expand the color spectrum easily achieve values at a minimum level of 90-92%.

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.

Every reliable image quality assessment must begin by selecting the most optimal factory mode. In the case of the tested model P7K/P79K, the choice was confidently made for the "Film" mode. It is this mode that presents an image closest to the creators' intentions, avoiding both the exaggerated brightness of dynamic mode and the excessive dimming known from eco settings. And it must be admitted that, for a device in this price range, the factory calibration is surprisingly decent, although it is not free from a few stumbles. The most noticeable flaw turned out to be an imperfectly adjusted white balance. A slight dominance of the blue component gives the image a subtly cool, chilly character, thus deviating from the exemplary neutrality that the director wanted to show us. The television performs much better in reproducing the grayscale in a standard dynamic range – the gamma curve is executed almost perfectly. A minor reservation can only be made for the darkest parts of the image, where a slight deviation from the norm causes a loss of some detail in the shadows. The most serious challenge for TCL's software, however, was the interpretation of the HDR signal, which is illustrated by the EOTF curve. The television follows its own, rather free path here – the darkest details are disproportionately brightened, followed by a noticeable slowdown in brightness increase for midtones. Fortunately, most of these imperfections are software-related issues that can be eliminated. With this thought in mind, we proceeded to the professional calibration process.

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.

The calibration process turned out to be a home run, especially in the context of standard dynamic range (SDR) content. We successfully managed to eliminate the TV's tendency to emphasize cool tones, restoring the whites to their natural neutrality. Furthermore, precise adjustments allowed us to correct a slight error in the gamma curve, so the darkest areas of the image regained their proper depth, without a trace of unnatural brightening. The effects are measurable and impressive – in the ColorChecker test, the vast majority of color reproduction errors fell below the perceptual threshold, achieving a deltaE value below 2. This is a result that would not shame much more expensive constructions. Unfortunately, in the case of HDR content, we hit a wall in the form of the inherent limitations of the panel itself. And although we managed to bring the colors in line, the software's specifics mean that the TV still adapts brightness in its own way, as evidenced by the persistent, non-standard EOTF curve. In summary, calibration brings tremendous added value, but one must be aware that it cannot overcome certain physical barriers. A slight boost in black levels, resulting from the lack of local dimming, and limited peak brightness mean that HDR content will not always be able to showcase its full potential. This is simply not the main task of this display; its true strength, especially after professional tuning, lies in the viewing of SDR materials.

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.

After a series of harsh evaluations, fortunately, the time comes for praise, and this is due to the TCL AiPQ image processor for its work in digital processing and content scaling. It should be noted right away that we are not talking about the level known from flagship designs; nevertheless, in the price segment represented by the P7K/P79K, the results achieved are more than solid. The feature that smooths tonal transitions performs particularly well, effectively eliminating posterization, which are the characteristic bands often visible in materials with higher compression, such as from the YouTube service. The algorithm can elegantly remove unwanted gradients, which ultimately looks really good. The television also competently handles upscaling, which is the task of raising low-resolution materials to 4K standard. The output image, although it may seem a bit too sharp out of the box, fortunately, is not a problem. The software allows for easy adjustment of this parameter using a sharpness slider, so the final appearance can be easily tailored to personal preferences.

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.

The issue of fluidity and sharpness of the image in motion is inextricably linked to the fundamental parameter of the panel, and in the case of the TCL P7K/P79K, we are dealing with a panel that has a native refresh rate of 60 Hz. This specification already defines its capabilities and makes it difficult to unequivocally recommend it to enthusiasts of dynamic sports broadcasts. During rapid camera movements, the image loses sharpness, and the panel itself also shows a slight tendency to blur, which may be noticeable to more sensitive viewers. Fortunately, not everything in this aspect has been left to chance. The manufacturer has implemented a simple motion smoothing system, which is primarily used in film materials recorded at 24 or 30 frames per second. Thanks to a dedicated slider, the user can independently decide on the final character of the motion – from a fully cinematic, slightly juddery image to achieving a very smooth, almost theatrical effect. It is a simple yet effective tool that allows users to tailor the viewing experience to their own preferences.

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.

Although on paper the native 4K@60Hz matrix might suggest that the TCL P7K/P79K is not a TV tailored for gamers, the reality turns out to be surprisingly different. On the contrary, the manufacturer has ensured a rich package of features that make it a very friendly companion for next-generation consoles. Onboard, we find key technologies such as ALLM, which provides automatic switching to low-latency mode, and VRR, or variable refresh rate, which eliminates screen tearing. The list is completed by support for Dolby Vision Gaming and a simple yet functional Game Bar. However, the real and extremely pleasant surprise is something else. It turns out that the TV easily supports high refresh rate signals of 120 Hz, but at lower resolutions – 1080p and 1440p. This is fantastic news for console owners who know full well how rarely games run in native 4K at a full 120 frames per second. The ability to choose between higher resolution and doubled smoothness is therefore an extremely sensible compromise.

In summary, although the P7K/P79K may not be the target screen for the most avid tournament gamers, it offers a package of options for the casual or occasional console user that is hard to find among many competitors at this price point.

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.
