TCL C655 Pro vs TCL P89K / TCL P8K

In the HDR effect quality category, the television TCL 655 PRO demonstrates decent capabilities, achieving a peak brightness of 550 nits. This allows for enjoyment of the HDR effects, which is particularly evident in scenes such as the first from the film Life of Pi or the last frame from The Meg. Nevertheless, the limited number of dimming zones causes some issues. While in bright scenes the television performs better than its lower model, in more demanding scenes, such as the second and fourth scenes from Sicario 2, it struggles. The dimming algorithm aims to achieve deep blacks, but at the cost of brightness – resulting in a drop in brightness of even half during those moments. In these more challenging scenes with small elements, it is hard to find any praise, and the HDR effect resembles more of an SDR. Regardless, the colour gamut coverage deserves commendation, which, like in the version without the PRO suffix, is at a very good level.

The maximum brightness of the TCL P8K is around 300 nits, although in real film scenes, the television maintains more of a level of about 250 nits. These values cannot be considered sufficient to achieve a full HDR effect – they are closer to a solid base for SDR content. Therefore, we will not see spectacular flashes, bursts of light, or moments in which the screen actually "blinds," as is the case with more expensive models. This makes the image somewhat flat, 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 reception. One of these is the coverage of the DCI-P3 colour palette at around 93–94%. Thanks to an additional QLED layer (PFS LED), the colours gain depth and intensity, clearly surpassing standard LCD panels. As a result, although there is a lack of the typical "wow effect" associated with HDR brightness, the image itself can impress with its saturation and vibrant tones, making film scenes pulse with colours and not appear strongly washed out.

Each of our television tests is conducted in film mode, which usually offers the best colour reproduction. Nonetheless, even this mode is not free from issues, as we noted in the model TCL 655 PRO.

In the case of HD content, the white balance distinctly shifts towards red, and this effect becomes particularly noticeable in a scene from Star Wars, where the white elements of the scenery take on a pink hue. For 4K HDR material, the situation is better, but there is a noticeable tendency to excessively emphasise the colour blue. As a result, the picture may appear artificially sharp, which proves to be uncomfortable for the eye over a longer period. The brightness characteristics also leave much to be desired. The Gamma graph indicates serious difficulties with excessive brightening, causing the overall presentation to appear washed out. Additionally, the EOTF curve reveals significant problems with reproducing very small elements – they are overly dimmed, as we detailed in the paragraph concerning HDR effects.

In Filmmaker mode, the TCL P8K revealed certain imperfections in image reproduction from the outset. We noticed that the television had a tendency to slightly brighten scenes – its gamma was somewhat low, causing the image to 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 graph clearly deviated from reference values. As a result, darker areas of the image appeared too gloomy, while brighter areas did not always reach the correct level of luminance. Another noticeable issue was a slight overemphasis on blue – the television stubbornly boosted this colour, causing certain parts of the image, especially skin tones and reds, to have a subtle purple tint. This is not a major flaw, but it is noticeable to a trained eye. Fortunately, most of these errors could be corrected during calibration. You can see the results of this adjustment in the graphs and photos below.

After calibrating the television TCL 655 PRO, a noticeable improvement in white balance is evident, where the tendency for the screen to have an excessive pink hue has been completely eliminated, which was previously visible in the factory mode. The image has taken on more natural tones, especially in white and light elements, positively affecting the overall perception of the picture. Regarding brightness characteristics, the Gamma chart has also improved – the screen is no longer overly bright, which previously made the image appear washed out. However, there are still some issues with the EOTF curve, which are difficult to eliminate due to the design of the television and its limited number of backlight zones. These limitations prevent achieving perfect results in this regard. Nevertheless, despite this minor flaw, the overall effect after calibration is truly outstanding, providing high picture quality and very good colour reproduction.

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.

The TCL 655 PRO television performs quite well with tonal transitions in lower quality materials. The "Gradual Smoothing" function at a low setting effectively smooths out tonal transitions, but this comes at the expense of losing some important details, such as the texture of objects. One positive aspect is that it does not negatively affect film grain, which helps maintain the natural appearance of the image.

In the context of digital processing, the television adds artificial sharpness. This may appeal to users who prefer a more vivid image. However, those who like a softer, subtler look may find this a drawback. Additionally, a downside is the cropping of the image due to overscan, which limits the field of view and trims the edges of the frame. This can be problematic in certain scenes - for example, news tickers.

The TCL P8K performs somewhat worse when it comes to the fluidity of tonal transitions in lower-quality materials. The television does offer a function to smooth out unwanted bands; however, its effectiveness leaves much to be desired. Even at the highest setting, it's hard to talk about any real improvement – at times the effect is almost the opposite of what is intended, as the function can introduce small artifacts and unnatural blurring on the screen.

On the other hand, upscaling – that is, 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. While there are slight "hard" edges typical of this class of equipment, this can be easily adjusted with the sharpness slider to suit personal preferences. The final effect is more than satisfactory, especially considering the price range in which this model is situated.

The TCL C655 PRO television is equipped with a 4K panel with a refresh rate of 60 Hz, making it best suited for watching films. Additionally, the "Flicker Reduction" feature allows users to adjust the smoothness of the image, giving them the choice between a smoother motion and a cinematic, frame-by-frame effect. Moreover, the television performs well with lower resolution materials, such as Full HD and 2K, offering a refresh rate of 120 Hz, which will certainly appeal to gamers who can enjoy a smoother picture at the expense of lower resolution.

TCL P8K is one of the cheapest televisions offering a refresh rate of 144 Hz, which in itself is quite an 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 the movement of the ball or dynamic actions look natural. However, this does not mean that the P8K is suitable solely for sports. On the contrary – it can also maintain appropriate dynamics in films without introducing the 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 judder 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 latter, on the other hand, reduces judder and improves sharpness during movement, although it can slightly darken the screen. Properly adjusting these two parameters allows for a really good balance between natural motion and fluidity. It has a 60 Hz refresh rate, but it is hard to say that it is a top-tier panel in terms of response speed. It will perform well for dynamic content, although more demanding users will notice that it is not a screen from the highest class in terms of motion clarity.

The TCL C655 PRO television offers an almost perfect set of features for gamers, supporting all the key technologies that significantly enhance the gaming experience. The ALLM feature automatically switches the television to low latency mode, resulting in improved responsiveness and minimal signal delay – particularly important in dynamic titles. VRR synchronises the screen refresh rate with the number of frames generated by the console, eliminating screen tearing and thus guaranteeing smoother gameplay.

Support for Dolby Vision in gaming mode allows for more detailed colour and contrast reproduction in games that support this format, while the Game Bar provides quick access to essential settings such as response time and latency level. Unfortunately, the model does not support 4K resolution at 120 Hz, which may disappoint the most demanding gamers. However, for those willing to forgo 4K, support for Full HD and 2K at 120 Hz delivers exceptionally smooth visuals, presenting an attractive alternative for enthusiasts of higher refresh rates.

Although the TCL P8K is a budget television, it cannot be said that it is unsuitable for gaming. On the contrary – it is a screen that can pleasantly surprise any gamer. It features two HDMI 2.1 ports, allowing for 4K output at 120 Hz without any issues. For those gaming on a PC, they will also be pleased to know that the television can operate with a refresh rate of up to 240 Hz at a lower resolution – a small thing, but it delights. Additionally, it comes with a full set of gaming features: automatic game mode, Game Bar with 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 television communicates well with next-generation consoles. The TCL P8K shows that a cheap screen doesn't have to mean giving up on fun. Certainly not in terms of gaming.
