TCL P7K / P79K vs Sony BRAVIA 5 (XR5)

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%.

Looking at similar results in terms of black levels and contrast, we expected the same stable performance as last year's model when it comes to HDR content. Unfortunately – and this must be said plainly – there has been a regression here that is hard to overlook. The paradox is that the peak brightness of the Bravia 5 can be impressive: in our synthetic tests, the television reached around 1000 nits in HDR. Sounds great, right? The problem is that this power does not always translate effectively to all movie scenes. When small, pinpoint elements appear on the screen, something that was usually refined with surgical precision in the case of Sony clearly falters this time. The algorithms try to maintain deep blacks around small objects, but the side effect is that details can be dimmed to the point of becoming barely visible. A case in point is the movie Sicario 2 – there, in some scenes, small light sources practically vanished as if someone had covered them with dark film.

Of course, not everything looks so dramatic. In simpler, brighter scenes, where the image is filled with a greater amount of light, the Bravia 5 shows that it can shine: literally and figuratively. At that point, the television achieves values in the range of 600–800 nits, which we observed in both synthetic tests and during movie screenings. The impression is truly positive; the brightness adds dynamism, and the colors appear vivid and fresh. However, there remains a certain dissonance. We feel a slight confusion because it is evident that something has gone the wrong way. Technological advancement – more zones, greater backlight power – has not been supported by the refined image management we usually associate with Sony. Fortunately, there are elements that have not been worsened and are instead at a very high level. We are talking about color reproduction. Thanks to the use of the PFS filter, the color gamut coverage is excellent – about 97% of DCI-P3 and 75% of BT.2020. These values allow for a truly wide color reproduction, giving films a natural and cinematic character.

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.

Sony Bravia 5 was of course tested in the best possible mode, which is the Cinema mode. Right out of the box, it offers the most natural colors, definitely better than anything provided by the "eco" or "dynamic" modes, which are more suitable for a store display than a living room. However, the Cinema mode itself does not guarantee that we can always expect cinematic image quality. In SDR content, we had practically no major complaints – the slightly warm white balance made the scenes take on a somewhat golden tone, but it was nothing that was glaringly obvious. However, the problem arose with HDR materials. Here, the color reproduction simply looked poor. The white balance was severely off – with an excess of blue and a noticeable lack of red. At times, it even resembled the store "super vivid image" mode, where everything is overexposed and artificially boosted.

This state of affairs made managing brightness seem too aggressive as well. The EOTF graph clearly showed that the television had issues with overexposing many scenes right out of the box. And while we know what Sony televisions are usually capable of, it was hard to remain indifferent here – which is why we quickly decided to go for calibration.

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 calibration, the situation changed drastically. We managed to tune the white balance so that entire scenes began to look more natural, and the image gained coherence and elegance. In HDR, we finally got rid of that unwanted blooming effect that had previously ruined some shots. Suddenly, it turned out that the Bravia 5 can extract much more from films than the first contact "straight out of the box" suggested. Yes, if we take a look at the graphs and compare them with the reference patterns, we can see that the start of the EOTF curve slightly deviates from the reference line. However, this is not so much a calibration error as a natural limitation of Mini-LED technology, which cannot be bypassed. Sony, instead of clinging to perfect black, prefers to prioritize the visibility of details – and in practice, it’s hard to disagree with that. We prefer to see the texture of the material on the screen rather than a pitch-black blob that obliterates all nuances.

The calibration itself made a significant difference. After about an hour spent on adjustments, we felt that the picture resembled that from the best cinema halls – of course on a home scale, but with the same sense of quality and refinement. And in such moments, we remember why we love Sony televisions: because once we fine-tune them, they can reward us with an image that captivates for long hours.

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.

Bravia 5 carries within it the genes of Sony, which remain intact – and thank goodness for that, because we are talking about absolutely remarkable digital image processing. There is a reason that for years it has been believed that it is this brand of television that sets the standard for how a screen should handle lower-quality materials. If someone is still watching classic television, old movies, or YouTube in lower resolution, here they get equipment that can turn such content into a surprisingly pleasant experience. On board, we find several tools worth activating. The first of these is "digital noise reduction." Set to a medium level, it works almost flawlessly – smoothing tonal transitions that usually pose the biggest challenge with low-quality materials, while not introducing any artificial artifacts. Importantly, it also does not remove the filmic character, or the natural grain that is an intentional element in many productions. Another advantage of Bravia 5 is the upscaling capabilities of the XR processor. The image presented after scaling is soft yet sharp and clear. The contours of characters are well-defined, and backgrounds retain their structure without excessive artificial sharpening. It’s hard to find a better television for watching lower-quality content – Bravia 5 only confirms why Sony is regarded as the benchmark in this field.

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.

Bravia 5 has a 120 Hz panel, which in itself sounds like an invitation to watch sports, fast matches, or spectacular action movies. However, the real magic begins only when MotionFlow comes into play – Sony's proprietary smoothing technology. Thanks to it, we can adjust the character of the image to our own preferences. The “smoothness” slider allows us to transition from a cinematic vibe with a slight “jitter” of the film frame to an almost theatrical fluidity, where every ball in the game glides across the screen like on a string. The higher the value, the smoother and more fluid it is; the lower – the more cinematic and natural. In the options, we also find an additional setting that Sony has called “clearness.” This is nothing more than the BFI function (which stands for black frame insertion), which aims to improve motion clarity. It sounds great in theory, but in practice, you need to use it with great caution. Why? Because all higher settings cause brightness drops of up to half, and in some cases, there can also be contour doubling. Therefore, if we want to use it, we recommend the lowest possible level – “1” out of the available ten. This way, we gain a little better motion clarity without risking a loss of half the image brightness.

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.

In the Bravia 5, there is significant progress compared to the X90L model from two years ago. The television offers literally everything that its predecessor had, but this time the issues that could irritate gamers have been fixed. The problems with setting up variable refresh rate (VRR) have disappeared, and there are no longer any issues with configuring HDR content in HGiG mode. In short: we get a device that simply works as it should without any fuss. The Bravia 5 thus has everything one could expect from a modern gaming television – and it could be advertised with the slogan "ready for PS5" without exaggeration. This is a statement we couldn't make about the X90L model. Hats off, Sony!

It's just a shame that in such a relatively high-priced model, a complete set of four HDMI 2.1 ports is missing. In everyday use, this won't be a problem for most people, but if someone has a console, soundbar, and additional equipment connected via HDMI, at some point there will be a need to either choose or juggle cables.
