TCL P7K / P79K vs Sony BRAVIA 5 (XR5)

When turning to the assessment of HDR performance, we must be clear and without marketing embellishments: the P7K/P79K is not, and was never intended to be, a master in this field. The maximum peak brightness that this panel can generate hovers around a mere 300 nits. This represents a threshold, a kind of thin red line between what can be considered a barely satisfactory HDR signal and what is, in fact, 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 portions of the scenes rarely exceeded the ceiling of 200-250 nits. Thus, this is not a television that would allow content realised in a wide tonal range to spread its wings, and this must be openly admitted.

Unfortunately, the issue of colour reproduction is presented with equal restraint. Although the manufacturer positions this model within 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 colour gamut reaches only 86%. In the context of the market, this is at best an average result, as most devices that employ additional layers to expand the colour spectrum easily achieve values at a minimum level of 90-92%.

Looking at similar results in terms of blackness and contrast, we expected equally stable performance as last year's model when it came to HDR content. Unfortunately – and this needs to be said outright – there has been a regression here that is hard to overlook. The paradox is that the peak brightness of the Bravia 5 is impressive: in our synthetic tests, the television achieved around 1000 nits in HDR. Sounds great, right? The problem is that this power does not always translate effectively to all film scenes. When small, point-like elements appear on the screen, something that had usually been polished with surgical precision in Sony's case is this time noticeably lacking. The algorithms attempt to maintain deep black around small objects, but the side effect is that details can be dimmed to such an extent that they become barely visible. Just consider the example of the film Sicario 2 – in some scenes there, small light sources practically disappeared, 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 more light, the Bravia 5 shows that it can shine: literally and figuratively. Then the television achieves values in the range of 600–800 nits, which we saw both in synthetic tests and during film screenings. The impression is really positive; the brightness adds dynamism, and the colours appear vibrant and fresh. However, there remains a certain dissonance. We feel a slight confusion because evidently something has gone in a direction it shouldn’t have. Technological progress – more zones, greater backlighting power – has not been supported by the well-crafted image management that we usually associate with Sony. Fortunately, there are elements that have not been worsened and are, in fact, at a very high level. We are talking about colour reproduction. Thanks to the application of the PFS filter, the colour palette coverage is excellent – around 97% DCI-P3 and 75% BT.2020. These are values that allow for truly broad colour reproduction, giving films a sense of naturalness and cinematic quality.

Every accurate assessment of image quality must begin with selection of the most optimal factory mode. In the case of the tested model P7K/P79K, the choice was made without hesitation for the "Film" mode. It is this mode that presents an image closest to the intentions of the creators, avoiding both the exaggerated brightness of the 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 has not escaped a few missteps. The most noticeable flaw turned out to be the not completely correctly set white balance. A slight dominance of the blue component gives the image a subtly cool, cold character, thus deviating from the exemplary neutrality that the director wanted to show us. The television performs much better in reproducing the greyscale in the standard dynamic range – the gamma curve is nearly exemplary. The only minor reservation could be made regarding 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 the TCL software, however, was interpreting the HDR signal, as illustrated by the course of the EOTF curve. The television follows its own, quite free path here – the darkest details are disproportionately brightened, after which there is a noticeable slowdown in the increase of brightness for midtones. Fortunately, most of these imperfections are software-related issues that can be eliminated. With this thought in mind, we began the process of professional calibration.

Sony Bravia 5 was of course tested in the best possible mode, which is the Cinema mode. Right out of the box, it provides the most natural colours, definitely better than anything offered by the "eco" or "dynamic" modes, which are more suited for a showroom display than for a living room. However, the Cinema mode alone does not mean we can always expect cinematic picture quality. With SDR content, we had virtually no major complaints – the slightly warmed white balance gave the scenes a somewhat golden tone, but it was nothing that was visually jarring. However, the problem arose with HDR material. Here, the colour reproduction simply looked poor. The white balance was heavily skewed – with an excess of blue and a clear lack of red. At times, it resembled the store's "super vibrant image" mode, where everything is overexposed and artificially boosted.

This situation also made brightness management seem overly aggressive. The EOTF graph clearly showed that the television had problems with overexposing many scenes right out of the box. And while we know what Sony televisions are usually capable of, it was difficult to remain indifferent here – thus we quickly decided to go for calibration.

The calibration process turned out to be spot on, particularly in the context of standard dynamic range (SDR) content. We successfully mitigated the television's tendency to emphasize cool tones, restoring the whiteness to its natural neutrality. Moreover, precise adjustments allowed us to correct a slight error in the gamma curve, ensuring that the darkest parts of the image regained their proper depth, without any trace of unnatural brightness. The effects are measurable and impressive – in the ColorChecker test, the overwhelming majority of colour reproduction errors fell below the perceptual threshold, achieving a deltaE value of under 2. This is a result that pricier models would not be ashamed of. Unfortunately, when it comes to HDR content, we encounter a barrier in the form of the inherent limitations of the panel itself. And although we managed to bring the colours into line, the software's characteristics mean that the television still adapts brightness in its own way, as evidenced by the persistent, non-standard EOTF curve. In summary, calibration adds immense value, but one must be aware that it cannot overcome certain physical barriers. The slightly elevated black level, due to the lack of local dimming, along with limited peak brightness, means that HDR content may not always be able to showcase its full potential. This is simply not the primary task of this display; its true strength, especially after professional tuning, lies in the viewing of SDR material.

After calibration, the situation changed dramatically. We managed to adjust the white balance so that entire scenes began to look more natural, and the image gained cohesion and elegance. In HDR, we finally got rid of that unwanted clipping effect that had previously marred some shots. Suddenly, it turned out that the Bravia 5 can extract significantly more from films than the “out of the box” impression suggested. Indeed, if we look at the graphs and compare them with the patterns, we can see that the beginning of the EOTF curve slightly deviates from the reference line. However, this is not so much a calibration error as it is a natural limitation of Mini-LED technology, which cannot be bypassed. Sony, instead of clinging to perfect black, prefers to prioritise the visibility of details – and in practice, it's hard to disagree with that. We would rather see the texture of the material on the screen than a pitch-black blob where all nuances are lost.

The calibration itself was truly beneficial. After about an hour spent on the settings, we felt that the image 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 like Sony televisions: because when 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 the field of digital processing and content scaling. It should be noted right away that we are not talking about the level known from flagship designs; however, in the price segment represented by the P7K/P79K, the results achieved are more than solid. The feature for smoothing tonal transitions performs particularly well, effectively eliminating posterisation, which are the characteristic bands often visible in highly compressed materials, for example, from the ChooseTV service. The algorithm adeptly removes unwanted gradients, which ultimately looks really good. The television also handles upscaling competently, which is the task of elevating low-resolution materials to 4K standard. The resulting image, although it may initially seem a bit too sharp, fortunately, is not a problem. The software allows for free adjustment of this parameter using a sharpness slider, making it easy to customise the final appearance to personal preferences.

Bravia 5 carries within it the genes of Sony, which have remained untouched – and thank goodness for that, because we are talking about absolutely remarkable digital image processing. It is no coincidence that for years it has been believed that it is televisions of this brand that set the standard for how a screen should handle lower quality materials. If someone still watches classic television, old films or YouTube in lower resolutions, here they get equipment that can transform such content into an unexpectedly 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 perfectly – smoothing tonal transitions, which usually cause the most trouble in low-quality materials, while not introducing any artificial artifacts. Importantly, it also does not remove the filmic character, meaning the natural grain that is intentionally present in many productions. Another advantage of the Bravia 5 is the upscaling capabilities of the XR processor. The image displayed after scaling is soft, yet at the same time sharp and clear. The contours of characters are clearly visible, while backgrounds retain their structure without excessive artificial sharpening. It’s hard to find a better television for watching lower quality materials – Bravia 5 only confirms why Sony is regarded as a benchmark in this field.

The issue of fluidity and sharpness of the image in motion is inextricably linked to a fundamental parameter of the matrix, and in the case of the TCL P7K/P79K, we are dealing with a panel with a native refresh rate of 60 Hz. This specification defines its capabilities from the outset and makes it difficult to unequivocally recommend it to enthusiasts of dynamic sports broadcasts. During fast camera movements, the image loses sharpness, and the panel also shows a slight tendency to smearing, 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 material recorded at 24 or 30 frames per second. Thanks to a dedicated slider, users can decide for themselves the final character of the motion – from maintaining a fully cinematic, slightly juddery image to achieving a very smooth, almost theatrical effect. It is a simple but effective tool that allows users to tailor the viewing experience to their own preferences.

Bravia 5 received a 120 Hz panel, which in itself sounds like an invitation to watch sports, fast matches, or spectacular action films. However, the real magic begins when MotionFlow – Sony's proprietary smoothness technology – comes into play. Thanks to it, we can adjust the character of the image to our own preferences. The "smoothness" slider allows you to transition from a cinematic feel with a slight "jitter" of the film frame to a nearly theatrical fluidity, where every ball in the match glides across the screen as if on a string. The higher the value, the smoother and more fluid it is; the lower it is, the more cinematic and natural it feels. In the options, we will also find an additional setting that Sony has called "clarity". This is nothing more than the BFI function (i.e., inserting black frames), which is meant to improve motion sharpness. It sounds great in theory, but in practice, one must use it with great caution. Why? Because all higher settings cause brightness drops of up to half, and in some cases, contour doubling also appears. Therefore, if we wish to use it, we recommend the lowest possible level – "1" out of the available ten. This way, we gain a bit better motion clarity without risking a loss of half the image brightness.

Although on paper the native 4K@60Hz panel might suggest that the TCL P7K/P79K is not a television tailored for gamers, the reality is 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 complemented 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 television easily supports a high refresh rate signal of 120 Hz but at lower resolutions – 1080p and 1440p. This is fantastic news for console owners, who know 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 passionate tournament players, for the casual or occasional console user, it offers a package of options that is hard to find among many competitors at this price.

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

It’s just a shame that this relatively high-priced model lacks a full set of four HDMI 2.1 ports. In everyday use, this won’t be a problem for most people, but if someone has a console, soundbar, and additional equipment hooked up via HDMI, at some point there will be a need to choose or juggle the cables.
