TCL P7K / P79K vs Sony Bravia 3 50' (VA)

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%.

Interestingly, the 50-inch version of the Bravia 3 performs slightly better in terms of brightness than its larger variants. In measurements, it achieved around 370 nits, which still does not compete with top-tier televisions, but is sufficient to suggest a semblance of HDR effect. For some users, this level will be acceptable, while others will view it as typical for SDR content, where striking highlights or strong contrasts are not expected. It must be clearly stated that the Bravia 3 is not a television for those looking to extract the maximum quality from the most challenging film materials.

This does not mean, however, that everything performs averagely. Sony has equipped this model with an additional PFS filter, which works similarly to solutions used in QLED televisions. As a result, the coverage of the DCI-P3 colour gamut has increased to over 91 percent. In everyday use, this means more vivid, saturated colours and also a more pleasing image texture. Even though it lacks strong lighting effects, films and series can look significantly more appealing than with its predecessor, the X75WL.

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 3 was primarily tested in film mode, which immediately proved to be the best choice among the factory settings. It is not an ideal picture, but compared to the eco mode that the television offers right out of the box, the difference is clear and it is a positive one. In film mode, one can notice a certain issue: the image appears too warm, which results from the lack of blue in the white balance. Nevertheless, in SDR content, the final effect can still be regarded as quite decent and satisfying for everyday viewing. Much more serious errors occur in HDR materials. The Color Checker analysis showed significant deviations, and poor brightness management, combined with limited colour gamut coverage, further exposes the shortcomings of the image in this mode. All of this means that HDR in the Bravia 3 edition is unconvincing and can spoil the impression left by a quite decent SDR content setup. Fortunately, this is not a hopeless situation. Various errors can be mitigated to some extent, and some can even be completely corrected through professional calibration. Therefore, we decided to check how the television would perform after such adjustments.

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.

Calibration allowed us to extract significantly more from the ChooseTV 3 than we could have expected at first. Firstly, it was possible to address the lack of blue, which had previously caused a noticeable warming of the image. After a slight adjustment to the white balance, most of the errors in the Color Checker measurements for SDR content practically disappeared. The shades of white became more natural, and the brightness management in gamma stabilised to a nearly perfect level, not exceeding the threshold of human eye perception. Therefore, it can confidently be said that in SDR content, after a few adjustments in settings, the ChooseTV 3 performs really brilliantly. Much worse, although still definitely better than before calibration, are the HDR contents. The white balance was brought into order, but the limitations of the IPS panel are insurmountable. The lack of local dimming means that even the smallest elements can be overexposed, which is immediately noticeable. Colour-wise, the effect is also improved, although far from ideal – many errors still exceed the threshold of four, or even five delta E units, meaning they remain visible to the human eye. It was already clear earlier that the ChooseTV 3 is not a television designed to impress with HDR quality. Nonetheless, it is pleasing to note that in SDR content, after calibration, the image can look truly excellent, and in this category, the television positively surprised us.

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 3 brings something more than just a shared name to the Sony television family. It stands out primarily for its ability to enhance the quality of inferior materials thanks to the processor used. Of course, we won't find the advanced XR chip known from more expensive models here, but nevertheless, it's worth noting that the image at lower resolutions looked surprisingly good. The upscaling worked effectively, and most parts of the screen were free from the typical excessive edge tearing characteristic of budget constructions. The feature enhancing the smoothness of tonal transitions is also noteworthy. In the high setting, it performs really well, effectively masking gradation imperfections without significant loss of detail. It does happen, however, that the algorithm overly smooths elements that should remain sharp – for example, faces – but overall, the effect is beneficial. The best results were achieved precisely at the highest setting, and this option could be recommended to those watching lower-quality content.

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.

The fluidity of motion has never been a strong point of televisions equipped with 60 Hz panels, and the Bravia 3 is no exception. Nevertheless, Sony has added something that may appeal to those more sensitive to the way images are displayed. This refers to the proprietary motion smoother, Motion Flow, which offers users a considerable amount of adjustment options. With it, one can make the image smoother, even theatrical, or stick to a more cinematic style with the characteristic judder that many associate with a filmic atmosphere. These functions work with content shot at lower frame rates, such as films and series recorded at 24 or 30 frames per second, which is the kind of material we encounter daily. It is precisely at this point that the motion smoother turns out to be one of the most important features in everyday use of the television, and here the Bravia 3 performs quite well.

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.

Bravia 3 is not a device for e-sports enthusiasts or fans of late-night marathons with a controller in hand. The lack of 120 Hz refresh rate and HDMI 2.1 ports puts an end to that discussion before it can even begin. This is a television for casual gamers who, after work, will fire up FIFA or racing games, not for someone who measures every frame in a spreadsheet. Nevertheless, Sony has included a few nice extras so that it isn't all so bare. ALLM works as it should, automatically switching the television to game mode (low latency). There's even a simple Game Bar, which is clear and straightforward. However, the biggest curiosity here is the PlayStation Portal app. Thanks to it, you can launch games from the PS5 wirelessly and see them immediately on the television screen. It sounds great, but it only takes a few minutes to feel significant delays. In our opinion, it is more of a showcase of capabilities than something you can use on a daily basis. If someone really wants to play, it is better to connect the console with an HDMI cable and forget about wireless issues.
