TCL P7K / P79K vs Haier M95E

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%.

If there is one category in which the Haier M95E absolutely shines, it is the HDR effect, driven by the raw power of the backlighting. This television cannot be denied the fact that it is a truly bright device. In both most film scenes and during our synthetic measurements, the panel easily achieved, and often even exceeded, the threshold of 1200-1500 nits. This has a direct impact on the viewing experience – the image has a punch and genuinely allows one to feel the magic of materials recorded in this format. However, one must be aware of a certain compromise. When exceptionally demanding scenes appear on the screen, full of small but intense points of light, the M95E does not lose its resonance or dim, but pays a different price for it. A very strong and noticeably distracting halo effect is generated around these bright elements. It is clear here that the algorithms controlling the dimming have been programmed to prioritise brightness and the visibility of the smallest details, even if this comes at the expense of pristine blacks. We are not entirely convinced that this is the healthiest approach; nonetheless, it must be acknowledged that the overall capabilities of the M95E in this regard are indeed significant. A huge advantage is the fact that we are dealing with a Mini LED QLED type construction. The use of a layer of quantum dots brings measurable benefits in the form of wide coverage of the colour palette, which in our tests reached nearly 96% of the DCI-P3 space. This guarantees that the television has full predispositions for displaying vibrant and properly saturated colours.

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.

Each television is primarily evaluated based on its default cinema mode – in this case, "Movie" – which theoretically should be the "best" and most faithful upon being taken out of the box. Unfortunately, in the case of the Haier M95E, the word "best" is certainly not synonymous with the word "good." Already during SDR viewing, the picture revealed evident problems: white balance skewed too much to red, and excessive, unnatural colour saturation led to visible colour deviations. What’s worse, the M95E also struggles with brightness management (gamma curve), excessively darkening the entire scene. Such behaviour is hard to commend, as it directly leads to details merging into shadows that are irrevocably lost in a black blob.

However, the real disaster occurred after switching to HDR material, while still remaining in "Movie" mode. It’s hard for us to guess who came up with such a fantastic idea – or perhaps it was simply a complete oversight of this stage by Haier's engineers – but instead of cinematic fidelity, the picture began to resemble a garish "Dynamic" mode. The white balance exposed immense problems with the blue colour, which in turn resulted in unnatural sharpening and artificial over-saturation of the entire scene. As if that weren’t enough, the EOTF curve characteristics mercilessly revealed that the television also has fundamental issues with local dimming management in this setting. We have not calibrated many Haier models in our career, but we already know for sure that the M95E definitely needs such 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.

The calibration process left us with extremely mixed feelings. On the one hand, we noted considerable success in the area of colour accuracy. By using the available options in the menu, we managed to tame the white balance and bring it down to an acceptable level. As a result, SDR content finally freed itself from the irritating red dominance, and the HDR image no longer resembled a vibrant, shop display mode. We also succeeded in clearly adjusting the entire colour palette and its saturation – perhaps not perfectly, but as much as the software allowed, and the difference was visible to the naked eye.

And unfortunately, this is where our list of improvements essentially ends, as the M95E simply did not allow for more. As we indicated earlier, most settings related to image brightness do not respond to our commands at all. This means that we were unable to grasp its fundamental characteristics in any way – neither the gamma curve nor the EOTF. In practice, the television in SDR content still tends to darken details, as confirmed by the elevated gamma, merging details in the shadows. Meanwhile, the EOTF curve in HDR mode still ruthlessly exposes all the aforementioned problems with chaotic local dimming management. And although the calibration process itself yielded a lot, removing most of the colour issues, in the end, we had to capitulate.

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.

Well, what happens to those colour connections when a lower quality material full of compression artifacts comes on screen? Unfortunately, we have some bad news for you. Although the menu contains an option responsible for smoothing tonal transitions in older content, we definitely DO NOT RECOMMEND using it. Its activation causes an avalanche of additional, hideous artifacts and noticeably blurs the entire image, and what's funniest – it often doesn't even remove those unwanted "jaggies" it was supposed to fight against. This function might as well not exist at all.

We can write many more positive remarks about the general upscaling process, which raises lower resolutions to the native 4K matrix. The image after upscaling looks really decent – it is neither overly jagged nor artificially smoothed. In this particular matter, the M95E simply performs well.

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.

In terms of motion fluidity and blur, our feelings are quite mixed, as the M95E is a paradox of a television. Let's start with absolute admiration: at the heart of the device is a 144Hz panel, but what truly impresses is its performance with 120Hz content, which is crucial for sports and console gaming. We must state with full responsibility that Haier has equipped this television with one of the best VA panels currently available on the market regarding the minimisation of blur. It is rare to encounter an LCD panel that offers such clean, sharp, and ghosting-free motion. In this respect, the M95E is simply phenomenal.

And that is precisely why the unpleasant surprise that awaits us on the software side is so painful. It turns out that this fantastic hardware potential is completely underutilised, as the television practically offers no effective options for improving fluidity. The motion smoothing systems that should assist with lower frame-rate content can indeed be found in the Menu, but they essentially do not respond to our settings. The conclusion is brutally simple: if you intend to watch high-fluidity material, you must be sure that the source is broadcasting it at native 120. In every other case, you must accept a rather raw, stuttering image, as the M95E will do nothing to smooth it out.

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.

When it comes to features for gamers, the Haier M95E presents some very strong arguments. First of all, it is fully ready for the new generation of consoles and powerful PCs. It is equipped with two full-fledged HDMI 2.1 ports, which seamlessly handle 4K signals at 120Hz, and even allow for gameplay at 144Hz. This is the foundation that guarantees us the full use of the potential of our gear. Moreover, the key technologies work flawlessly here. The television flawlessly detects the console and automatically switches to low latency mode (ALLM), so we don’t have to fiddle with the settings. The frame synchronization (VRR) works just as efficiently, eliminating annoying screen tearing when game fluidity slightly drops. Considering the incredibly low motion blur of the panel, which we have already mentioned, the M95E creates a really comfortable and responsive gaming environment. Of course, this is not a perfect package. A dedicated "Game Bar," which is a handy menu for gamers, would be useful, but this is essentially just a nice addition. A more serious failing is the lack of support for the HGiG standard, which complicates the perfect HDR configuration on the console and may lead to overexposures. Despite these shortcomings, the basic "gaming" set that the M95E offers is really solid and fully functional.
