TCL P7K / P79K vs Haier M95E

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%.

If there is one category in which the Haier M95E undoubtedly shines, it is the HDR effect, driven by the raw power of the backlighting. This TV cannot be denied that it is a truly bright device. Both in most movie scenes and during our synthetic measurements, the panel easily achieved and often even exceeded the threshold of 1200-1500 nits. This directly translates to the viewing experience – the image has a striking impact and truly allows you to feel the magic of materials recorded in this format. However, one must be aware of a certain compromise. When particularly demanding scenes filled with small, yet intense bright spots appear on the screen, the M95E does not lose its punch nor dims, but it pays a different price for it. A very strong and noticeably distracting halo effect is generated around these bright elements. It is evident here that the algorithms controlling the dimming have been programmed to prioritize brightness and visibility of the smallest details, even if this comes at the cost of flawless black levels. We are not entirely convinced that this is the healthiest approach; however, it must be acknowledged that the overall capabilities of the M95E in this regard are quite substantial. A significant advantage is the fact that we are dealing with a Mini LED QLED construction. The use of a quantum dot layer brings tangible benefits in the form of wide color gamut coverage, which in our tests reached almost 96% of the DCI-P3 color space. This guarantees that the television has full predispositions to display vibrant and appropriately saturated colors.

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.

We evaluate every television primarily based on its default cinema mode – in this case "Film" – which theoretically should be the "best" and most accurate right out of the box. Unfortunately, with the Haier M95E, the word "best" is absolutely not synonymous with the word "good." Even during SDR viewing, the picture revealed obvious issues: white balance skewed too much towards red, and excessive, unnatural color saturation led to visible color deviations. Worse still, the M95E also has trouble managing brightness (gamma curve), excessively darkening the entire scene. Such behavior is hard to commend, as it directly causes details in the shadows to blend into a black blob, which are irretrievably lost.

However, the real disaster struck after switching to HDR material while still remaining in "Film" mode. It's hard 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 the image, instead of cinema fidelity, began to resemble the bright "Dynamic" mode. The white balance exposed huge issues with the blue color, which in turn resulted in unnatural sharpening and artificial oversaturation of the entire scene. As if that weren't enough, the EOTF curve characteristics ruthlessly revealed that the television also has fundamental problems with local dimming management in this setting. We haven't calibrated many Haiers in our career, but we know for sure now that the M95E definitely needs it.

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.

The calibration process left us with extremely mixed feelings. On one hand, we noted significant success in the area of colorimetry. Utilizing the options available in the menu, we managed to tame the white balance and bring it down to an acceptable level. As a result, SDR content was finally freed from the annoying red dominance, and the HDR image no longer resembled a vibrant, store demonstration mode. The entire color palette and its saturation were also clearly corrected – perhaps not perfectly, but to the extent that the software allowed, and the difference was visible to the naked eye.

Unfortunately, this is where our list of corrections basically ends, as 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 we were unable to control 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, which was confirmed by the inflated gamma, merging details in the shadows. On the other hand, the EOTF curve in HDR mode still mercilessly exposed all the previously mentioned issues with chaotic local dimming zone management. And while the calibration process itself yielded quite a lot, removing most of the color issues, ultimately 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 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.

Well, what happens with those color transitions when lower quality material full of compression artifacts comes on screen? Unfortunately, we have some bad news for you. Although we can find an option in the menu responsible for smoothing tonal transitions in older content, we definitely DO NOT RECOMMEND using it. Its activation causes a barrage of additional, ugly artifacts, noticeably blurring the entire image, and the funniest part – it often doesn’t even remove those unwanted “stairs” it was supposed to fight against. This feature might as well not exist at all.

We can write many more positive things about the overall upscaling, which is the process of raising lower resolutions to the native 4K matrix. The image after upscaling looks really good – it's neither overly jagged nor artificially smoothed. In this particular matter, the M95E simply delivers.

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.

When it comes to motion fluidity and ghosting, our feelings are quite mixed because the M95E is a paradoxical television. Let’s start with the absolute delights: 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 the television with one of the best VA panels currently available on the market when it comes to minimizing ghosting. It is rare to encounter an LCD panel that offers such clean, sharp, and ghost-free motion. In this respect, the M95E is simply phenomenal.

And this is exactly why the unpleasant surprise waiting for us on the software side is so painful. It turns out that this fantastic hardware potential is completely untapped, as the television practically offers no functioning options for improving fluidity. The smoothing systems, which should assist with lower frame rate content, can indeed be found in the Menu but 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 transmitting it natively at 120. In every other case, you must resign yourself to a rather raw, choppy image because the M95E will not help smooth it out in any way.

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.

When it comes to features for gamers, the Haier M95E presents some really 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 handle 4K signals at 120Hz effortlessly and even allow for gaming at 144Hz. This is a foundation that guarantees us full utilization of the potential of our equipment. Moreover, the key technologies work flawlessly here. The television accurately detects the console and automatically switches to low latency mode (ALLM), so we don’t have to dig into the settings. The frame synchronization (VRR) also works smoothly, eliminating the annoying tearing of the image when the game's fluidity slightly drops. Considering the remarkably low motion blur of the panel, which we have already mentioned, the M95E creates a truly comfortable and responsive gaming environment. Of course, this is not a perfect package. A dedicated "Game Bar," which would be a handy menu for gamers, would be a nice addition, but in essence, it is just a nice extra. A more serious shortcoming is the lack of support for the HGiG standard, which complicates the ideal HDR configuration on the console and can lead to overexposures. Despite these shortcomings, the basic "gaming package" offered by the M95E is really solid and fully functional.
