TCL P7K / P79K vs Hisense U7Q PRO

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%.

U7Q PRO is truly a bright television. In synthetic tests, it achieved over 1500 nits, which is an outstanding result for this price range. Such brightness – at least in theory – allows for displaying HDR content as intended by creators, even in more demanding scenes with strong light. In practice, it can be very good, but not always perfect. In bright scenes with a large surface area – such as the test screen with intense sunlight from the movie "Pan" – U7Q PRO makes a huge impression. It can almost blind with light, which is definitely an advantage in the context of HDR content. Unfortunately, this is not always maintainable when a lot of small bright details appear on a dark background. In such moments, local dimming algorithms decide to dim some bright elements to maintain good black levels – and the side effect is that some details simply disappear from the frame. This is a classic compromise in mini-LED televisions – and U7Q PRO is no exception. However, with such a large number of dimming zones, one could expect a somewhat more mature algorithm responsible for controlling them. Fortunately, the overall reception of HDR content is very positive. U7Q PRO is not only bright but also colorful; thanks to the PFS LED (QLED) coating, the coverage of the DCI-P3 color palette is at 95%, and BT.2020 is around 73%.

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 tested the U7Q PRO in the best possible picture mode that this model offers – Filmmaker Mode. And indeed, it is this mode that performs best in terms of color reproduction. But that doesn't mean it's perfect. In our test unit, both in SDR and HDR content, the image had a slightly cooled tone. The white balance was shifted towards blue, which made the overall impression feel a bit "cooler." It's not glaring, but definitely noticeable – especially on white backgrounds that, instead of neutral, appeared slightly bluish. Additionally – as we mentioned earlier – the television tends to slightly brighten and oversaturate the image, which is also confirmed by the gamma and EOTF charts. All of this together means that without calibration the image may seem a bit unnatural – too cool, with slightly exaggerated dynamics. That's why we decided to conduct our own calibration – and its effects and charts can be seen below.

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.

Thanks to calibration, we managed to tame the white balance in both SDR and HDR content. For SDR materials, the effect is really very good – the image becomes neutral, consistent, and simply pleasant to view. Everything looks as it should.

The performance in HDR is a bit worse. Although the white balance looks correct and overall the image gains in naturalness, unfortunately, delta E errors remain noticeable. Why? Because Hisense does not give us full control over how the U7Q PRO manages brightness in HDR mode. This is where the limitation appears. When we look at the EOTF curve for HDR content, we can clearly see what we mentioned earlier – at the beginning of the graph, there is a noticeable drop, meaning the television dims the smallest sections more than it should. On the other hand, the brightest elements can be illuminated a bit too much. As a result, some details are lost, others are too aggressive, and overall control over brightness does not always align with what we are trying to achieve during calibration.

Does the image look better after calibration? Definitely yes, in terms of color. But when it comes to managing brightness in HDR, we have to accept that the Hisense U7Q PRO will do it its own way.

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.

If someone happens to come across older materials where the issue of color banding appears – Hisense has a solution for that. In the U7Q PRO, we find a feature called "Smooth and Gradient Picture." Set to the "Medium" level, it works really well – it eliminates most of the gradation issues while not smoothing out the entire image, like blur in Photoshop. 😉 Film grain remains, details do not disappear – this is exactly how it should work. Kudos for the implementation!

As for scaling weaker materials, it’s just good. It’s not at the level of the most expensive TVs with advanced upscaling, but older content looks good. There is some mild aliasing at very low resolutions, but that’s completely normal and hard to avoid. On the plus side – even with the oldest materials, there is no overscan effect; the image is not cropped or artificially stretched.

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.

“Speed” – this word was mentioned most frequently during our tests of the U7Q PRO. The television is equipped with a 165 Hz panel, which is impressive in itself – especially since we are talking about a model in the mid-price range. Of course, PC gamers will benefit the most from its full capabilities, but even during everyday viewing, it is evident that this is a fast and efficient panel. Like most modern televisions, the U7Q PRO can also enhance the smoothness of movies that are primarily shot in 24 frames. In the menu, there is a slider that allows you to adjust the effect to your preferences – from a more cinematic feel, with subtle motion, to stronger smoothing with the characteristic “soap opera effect.”

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.

The Hisense U7Q PRO is a television that seems almost designed for gamers. It has practically everything you could expect from a gaming screen: variable refresh rate (VRR), automatic mode (ALLM), and as many as four HDMI 2.1b ports with full bandwidth of 48 Gb/s. Additionally, there is a clear and quite functional Game Bar, as well as a well-implemented Dolby Vision GAMING mode that works seamlessly with Xbox Series S and X consoles.

Sounds like perfection? Well, almost. Unfortunately, Hisense has yet to implement the HGiG feature, which is the system's limit on tone mapping on the TV's side. This means that when configuring HDR brightness on the console, we do it "by eye" or look for settings in online guides because the screen doesn't show the real range of its brightness. It's a pity - because HGiG makes it easier to match the console to the TV and helps avoid clipping or overly dark scenes in HDR games.

Fortunately, the other elements work very well. Signal delay (input lag) is low, responsiveness is excellent, and the handling of other functions is flawless. And although not everything worked perfectly, the U7Q PRO can still be recommended to gamers without hesitation.
