Hisense U7KQ vs TCL P89K / TCL P8K

Describing the HDR effect in the Hisense U7KQ 100-inch model is not straightforward and requires context. In bright scenes, the TV achieves over a thousand nits of brightness, delivering vivid and realistic images that meet expectations for this class of equipment. However, performance declines in darker scenes. In mixed shots, like those in Gemini Man, the TV maintains a brightness level of 700 nits, providing good quality. The issue arises in very dark scenes with small light sources, where the TV limits its capabilities to preserve black levels. This results in a lack of the "WOW" effect, making such frames feel less like true HDR.

The maximum brightness of the TCL P8K is around 300 nits, although in actual movie scenes, the TV maintains more around 250 nits. These values cannot be considered sufficient for achieving a full HDR effect – they are more akin to a solid base for SDR content. Therefore, we won’t see spectacular flashes, bursts of light, or moments when the screen truly “blinds” you, as is the case with more expensive models. The image is somewhat flattened, and the differences between light and shadow are more symbolic than realistic. Fortunately, TCL has a few aces up its sleeve that save the overall impression. One of them is the coverage of the DCI-P3 color gamut at around 93–94%. Thanks to an additional QLED layer (PFS LED), colors gain depth and intensity, clearly surpassing standard LCD panels. As a result, although the typical “wow effect” associated with HDR brightness is lacking here, the image can still impress with its saturation and vibrant tones, making movie scenes pulse with colors and avoiding a heavily faded appearance.

The best factory mode we measured on the Hisense U7KQ was "Filmmaker." However, its performance still left room for improvement. Let's start with the gamma chart, which affects image depth and contrast. The orange line, which represents the REC.709 standard reference value, begins at 2.4. Looking at the white multi-point line that indicates the measured value, a noticeable drop to 2.0 indicates a decrease in contrast, making the image lack depth and resulting in a "milky" effect. Next, we checked the white balance, which, although minor, can drastically affect the overall image quality if poorly calibrated. Initially, the chart was fine, but red and blue began to dominate, giving all test materials an unpleasant tint. Fortunately, with the advanced colour management system (CMS) and 2- and 20-point grayscale adjustment tools, we managed to significantly improve SDR material performance, as reflected in low deltaE errors and well-calibrated gamma and white balance.

In Filmmaker mode, the TCL P8K revealed certain imperfections in image reproduction from the start. We noticed that the television tends to slightly brighten scenes – its gamma was somewhat lowered, which made the image appear slightly "washed out," lacking depth, as if the contrast had slipped out of control. This was most evident in HDR content, where the EOTF brightness curve clearly deviated from the reference values. As a result, the darker parts of the image looked too gloomy, while the brighter sections didn't always reach the proper level of luminance. A second noticeable issue was a slight oversaturation of blue – the television stubbornly boosted this color, which caused some parts of the image, especially skin tones and reds, to have a slight purple tint. This is not a major flaw, but to a discerning eye – noticeable. Fortunately, most of these errors could be corrected during calibration. You can see the results of this adjustment in the graphs and photos below.

In SDR mode, after calibration, the Hisense 100U7KQ performs excellently. Regarding colour reproduction there is nothing to criticise – both pastel and highly saturated colours are displayed according to the Rec. 709 standard, ensuring the image looks natural and in line with the director's intent. Viewers can enjoy an authentic visual experience, with colours and tonal subtleties faithfully represented.

In HDR mode, however, there is a noticeable boost in bright tones. The TV attempts to enhance the image, which can lead to an artificial brightening. This phenomenon becomes more apparent in real scenes, where bright areas of the image may be excessively brightened. While colours in HDR are generally good, they are intentionally over-boosted by the manufacturer, which can affect their naturalness.

This approach to HDR may not appeal to everyone, particularly those who value authenticity and fidelity to the original colours. However, for those who prefer more dynamic and vivid images, the boost in bright tones can add extra brilliance and impact to scenes.

After calibration, the TCL P8K showed a completely different face. It managed to achieve nearly perfect, even reference-level color reproduction in both SDR and HDR content. The screen no longer had a tendency towards a cool tint, and the white balance was perfectly balanced. The gamma values for SDR material also finally look as they should – the image has the proper depth and no longer appears washed out. The only remark that can still be made about the P8K concerns its "Chinese" traits, known from most TCL models. The TV still likes to manipulate saturation in HDR content in its own way – sometimes slightly boosting it, sometimes smoothing it out, which means the effect is not always fully predictable. Nevertheless, after calibration, the colors look stunning, and their accuracy is truly surprising. In most cases, measurement errors dropped below values of 1-2, which is a result that significantly more expensive models would not be ashamed of.

Although the Hisense 100U7KQ is equipped with a feature to reduce posterisation called "Smooth Gradation," we did not notice a significant effect from its operation. Material subjected to strong compression, such as YouTube videos, still showed uneven, cut-off tonal transitions, which did not look particularly favourable. While this is the fault of the material itself and not the television, it would be beneficial if there were a function to mask these problems, similar to screens from competing brands.

The image scaling, which is crucial when playing lower resolution content, is average. Details are not excessively blurry, and the image is not "smeared," but there is noticeable aliasing on the edges of objects, such as branches, and a halo effect around characters and text. While the television performs fairly well, there is still room for improvement, particularly in the context of displaying lower-quality material.

The TCL P8K performs somewhat worse when it comes to the fluidity of tonal transitions in lower quality materials. The television does offer a feature to smooth out unwanted bands, but its effectiveness leaves much to be desired. Even at the highest setting, it’s hard to say there’s a real improvement – at times the effect is even the opposite of what was intended, as the feature can introduce small artifacts and unnatural blurriness on the screen.

On the other hand, upscaling, or scaling the image to 4K resolution, looks significantly better. The P8K handles this task surprisingly well – HD content, and even SD, is enhanced in an aesthetically pleasing manner without excessive loss of sharpness. There are indeed slight "hard" edges typical of this class of equipment, but this can easily be adjusted with the sharpness slider according to personal preferences. The final effect is more than satisfactory, especially considering the price range in which this model is located.

The Hisense 100U7KQ TV correctly receives a 4K signal up to 144 Hz, allowing for very smooth images in high resolution. When the resolution is reduced to Full HD, the TV can handle up to 240 Hz, but this signal can only be obtained from a PC. However, the use of this feature is limited by several factors.

Firstly, Full HD resolution on a large TV screen may feel insufficient, affecting image quality. Additionally, the panel's response time isn't fast enough to fully utilise the 240 Hz refresh rate. As a result, at such a high refresh rate, significant overdrive occurs, leading to noticeable motion blur and "ghosting" behind moving objects.

The motion smoothing feature, which works up to 120 Hz, is also worth noting. This is especially useful for sports and movies where motion fluidity is crucial. The TV provides stable operation of this feature, minimising generated artefacts. Motion fluidity can be adjusted using two sliders – one for smoothness in movies and another for reducing blur in sports content.

In summary, while the Hisense 100U7KQ TV offers impressive image refresh rates, the panel's response time and resolution may affect the overall benefits of these features. Nevertheless, the motion smoothing function enhances the viewing experience of dynamic content.

TCL P8K is one of the cheapest televisions offering a 144 Hz refresh rate, which in itself is already a significant advantage in this price segment. Thanks to the fast panel, this model can confidently be recommended to both sports fans and video gamers – the image is smooth, and movements of the ball or dynamic actions look natural. However, this does not mean that the P8K is only suitable for sports. On the contrary – it can maintain the right dynamics in movies as well, without introducing an artificial effect of "theatricality," as long as we set the parameters wisely. The television is equipped with a motion smoother called "Motion Clarity," which features two sliders: blur reduction and flicker reduction. The first is responsible for smoothing the image by generating additional frames, which increases fluidity but may cause a slight soap opera effect. The second, on the other hand, limits flicker and improves sharpness in motion, although it may slightly darken the screen. Appropriately adjusting these two parameters allows for a really good balance between natural movement and fluidity. The 60 Hz panel is good for dynamic content, although more demanding users will notice that it is not a top-tier display in terms of motion clarity.

The Hisense U7KQ TV supports all the key features when using Xbox or PlayStation consoles, including high refresh rates, low input lag, and a game bar. Most of these features work well, providing a satisfying gaming experience.

However, VRR (Variable Refresh Rate) technology does not perform optimally. When activated, VRR disables the local dimming function, significantly reducing image quality. In VRR mode, the TV struggles with maintaining good contrast and high brightness in HDR, resulting in unsatisfactory image quality. As a result, VRR mode may be infrequently used by gamers due to these limitations.

Additionally, the TV does not support the HGIG (HDR Gaming Interest Group) mode, which optimises HDR image quality in games. Without this mode, tone mapping issues arise in the TV and the console, leading to lower-quality HDR games, which could affect the overall gaming experience.

In summary, while the Hisense U7KQ offers many features for gamers, certain key aspects, such as VRR performance and HGIG support, may not meet the expectations of more demanding users. Nonetheless, the TV supports most standard gaming functions, making it suitable for gamers.

Although the TCL P8K is a budget TV, it certainly can’t be said that it’s not suitable for gaming. On the contrary – this is a screen that can pleasantly surprise any gamer. It features two HDMI 2.1 ports, allowing us to easily output 4K at 120 Hz. For those gaming on PC, they will also appreciate the fact that the TV can even operate at 240 Hz refresh rate in lower resolution – a small thing, but it’s nice. In addition, there’s a full set of gaming-specific features: automatic game mode, Game Bar for quick parameter previews, VRR, HGiG, and support for Dolby Vision in games. All of this makes gaming on the P8K a truly enjoyable experience – the picture is smooth, the response is quick, and the TV communicates well with next-gen consoles. The TCL P8K shows that a cheap screen doesn’t have to mean giving up fun. Definitely not when it comes to gaming.
