Compare TCL C655 Pro vs Sony X90L

TCL C655 PRO is an extension of the basic model from this series, and although the name may suggest only minor differences, the "PRO" suffix actually means a lot. The biggest change compared to its less advanced sibling is the picture quality. The manufacturer opted for the implementation of local dimming technology, which significantly improves black levels and contrast. The television is capable of offering a more refined picture. Thus, TCL C655 PRO clearly outperforms the more budget version in this respect. The applied QLED panel further enhances the coverage of a wide color palette, delivering vibrant and saturated colors, which works great for both movies and dynamic content such as games. In terms of gaming, just like the basic version, TCL C655 PRO offers a range of useful features for gamers – including ALLM, VRR, and Game Bar – which greatly enhance the gaming experience. The television can also adjust the screen refresh rate to lower resolutions, meaning that despite supporting 4K at 60 Hz, in Full HD or 2K, one can enjoy a smoother image thanks to 120 Hz. In everyday use, the Google TV operating system performs excellently. The intuitive interface, personalized recommendations, and wide access to streaming applications such as Netflix, YouTube, or Disney+ make the TV enjoyable to use. This makes it easy to overlook the lack of recording features and picture-in-picture (PiP), which is not a major issue given the rich offering of applications. If we can afford that small difference in price, we definitely recommend the TCL C655 in the PRO version.

Sony X90L is a higher-end model from the Japanese manufacturer, which premiered in 2023 but will continue successfully in 2024 as well. The Sony brand and the name Bravia are associated with excellent picture quality, and this model confirms that reputation – it offers great brightness and very good black levels. Despite having fewer local dimming zones than its competitors, it makes up for it with an advanced algorithm. Additionally, after calibration, the television presents very well-rendered colors, resulting in a natural and cohesive image reminiscent of IMAX theaters. In everyday use, X90L performs excellently, mainly thanks to the image processor that effectively scales lower resolution content and the recording function from the built-in tuner, which is becoming increasingly rare in today’s televisions. Sony is also closely tied to the world of PlayStation, and in this regard, X90L Sony does not disappoint. It is equipped with HDMI 2.1, VRR, ALLM, and a convenient Game Bar, making it a good choice for gamers who expect smooth gameplay and quick response. However, even in such a successful model, there are some drawbacks. Gamers may be disappointed by the lack of support for HGiG, which could improve image quality in HDR games. Additionally, Sony has not yet released an update that would reduce input lag in Dolby Vision mode – something that has been achieved in the higher model, the A95L. Those who prefer slimmer devices should know that although Sony X90L looks elegant due to its aluminum frame, it is not among the thinnest televisions on the market. Even though X90L has already been on the market for a year, it remains a solid device that combines good picture parameters with functionality and support for gamers. It is a successful choice for those looking for a versatile high-end television.

The TCL 655 PRO television, equipped with a VA panel, provides solid contrast; however, the key role in improving image quality is played by local dimming technology. The tested 55-inch variant has 84 zones of backlighting, which significantly enhance contrast compared to the model without the "PRO" suffix, and this effect is clearly visible in the first three tested scenes. It is worth adding that larger versions of this television naturally have more zones, which translates into even better contrast. Of course, as with any LCD television, certain drawbacks remain—particularly noticeable in the tested scenes 4 and 5, where smaller bright elements lose quite a bit of quality. Nevertheless, considering the price of the device, the TCL 655 PRO makes a strong impression and stands out well in the category of black levels and contrast.

The Sony X90L television is equipped with a VA panel and in the tested size of 65' has 88 dimming zones. It may seem that such a number of zones does not make a great impression, but thanks to the local dimming algorithm, the television handles blacks very well. This is clearly visible in the first and third test slides, where the contrast reaches nearly 100,000:1. In more demanding scenes, the X90L does not achieve such spectacular results anymore – a contrast level of 6000:1 is simply acceptable. The light separation is really good, confirmed by the scene from the movie "Oblivion". However, the small number of dimming zones causes the halo effect to be visible, especially in the test film from "Sicario 2," where the helicopter lights cause quite a noticeable flare on a large area of the screen. Despite the small number of dimming zones, the Sony X90L does a really good job of reproducing blacks. Although it does not compare to the highest series of miniLED or OLED televisions in terms of black depth and contrast level, it offers solid results that are sufficient for demanding users in most cases.

In the HDR effect quality category, the TCL 655 PRO television shows decent capabilities, achieving 550 nits of peak brightness. This allows for enjoyment of HDR effects, which is clearly visible in scenes such as the first from the movie Life of Pi or the last frame from The Meg. However, the limited number of dimming zones causes some problems. 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 for deep blacks, but at the cost of brightness – which in these moments leads to a decrease in brightness by as much as half. In these more challenging scenes with small elements, it is hard to find any praise, and the HDR effect resembles rather SDR. Nonetheless, the coverage of the color palette deserves commendation, which, like in the version without the PRO suffix, is at a very good level.

HDR on the Sony X90L television looks promising. The luminance chart showed that the TV has a solid power reserve, reaching a maximum of 1000 nits in synthetic tests. But how does it perform in real scenarios? In scenes such as the first one from Life of Pi or the final sequence from The Meg, the TV can deliver this power on HDR content, achieving around 800 nits. Unfortunately, displaying small light elements on a black background, as in the scene from Sicario 2, poses greater challenges for the X90L – here the results reach about 600 nits. Despite this, when looking at competitive models with mini-LED technology, the effect looks very good and can shine enough to impress us. The color gamut coverage is also noteworthy, with a result of 96% for DCI-P3 and 76% for BT.2020, indicating good color reproduction in HDR content.

Each of our TV tests is conducted in movie mode, which usually offers the best color reproduction. Nevertheless, even this mode is not free from problems, as we noted with the TCL 655 PRO model.

In the case of HD content, the white balance clearly 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 looks better, but there is a tendency to excessively enhance the blue color. As a result, the image can appear artificially sharp, which proves to be uncomfortable for the eye over a longer period. The brightness characteristic also leaves much to be desired. The Gamma chart indicates serious difficulties with excessive brightening, causing the overall presentation to look washed out. Additionally, the EOTF curve reveals significant issues with the reproduction of very small elements - they are excessively dimmed, as we detailed in the paragraph regarding HDR effects.

The best mode in Sony televisions is the IMAX Enhanced mode. Although IMAX is mainly associated with the cinematic experience, here the color reproduction right out of the box is average. In the case of lower quality materials, such as HD – regular TV or YouTube – it is worth paying attention to the white balance. It is characterized by a deficit in red and an excessive dominance of blue, which gives the image a pinkish hue. The brightness characteristic, or gamma, for HD content is quite decent, but a slight boost may cause the image to become washed out and appear as if it is behind a light fog.

In 4K HDR content, the situation looks a bit different. The white balance shows a significant boost in blue, which makes the image appear unnaturally sharp and gives it an artificial feel. Such an exaggeration in color reproduction may not appeal to everyone, especially if one prefers more realistic shades. Additionally, the EOTF curve in Sony X90L looks quite decent at first glance. However, at the end of the graph, there are certain fluctuations that suggest the television is trying to maintain the appropriate brightness to avoid overexposing larger elements.

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

Sony offers many tools to improve image quality, including two additional image modes that we decided to use during testing and apply calibration to them. This solution significantly facilitates the calibration work and is very effective, provided that the right tools are available. In the case of HD content, the white balance has been almost perfectly aligned – only one shade of gray exceeds the error value of "1", which is an excellent result. The same can be said about the brightness characteristic (gamma), which looks nearly perfect, with microscopic deviations of around 0.01.

In the case of 4K HDR content, the situation is not as ideal. Although the white balance has been significantly improved, it has not been possible to completely eliminate the dominance of blue color. Nonetheless, errors in the Colour Checker test only occasionally exceed the value of "2", which means that image distortions are practically unnoticeable. As for the EOTF curve, it is worth activating the filter in the upper right corner "EOTF in Movies" – the graph looks correct, but the television encounters difficulties illuminating very small elements, which results from the limited number of backlight zones. Despite these minor flaws, it is thanks to the calibration carried out that the IMAX Enhanced mode in the Sony X90L makes watching movies resemble a true cinema experience.

Tonal transitions are really fine and would deserve a high rating (8), however, the rating was clearly lowered for another reason - the image is artificially sharpened despite the "sharpness" parameter being set to 0. As a result, the image is unpleasant to look at.

The smoothness of tonal transitions in Sony X90L is outstanding. The gradation is beautiful on high-quality sources such as 4K streaming. One can only notice slight banding on more demanding gradients, but the overall effect is very good and should satisfy even the more discerning viewers.

The TCL 655 PRO television handles tonal transitions in lower-quality materials quite well. The "Gradual Smoothing" feature at a low setting effectively smooths out tonal transitions; however, this comes at the cost of losing some important details, such as the texture of objects. A positive aspect is that it does not negatively affect film grain, which helps maintain the natural look 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 favor a softer, subtler look may find this to be a drawback. Additionally, a downside is the image cropping due to overscan, which limits the field of view and trims the edges of the frame. This can be problematic in certain scenes - e.g., news tickers.

The Sony X90L TV features a tone transition smoothing function known as Smooth Gradation, which is incredibly effective. Even at the "low" setting, the effects are satisfactory, but at the "medium" setting, it works like a dream – we recommend using this option for the best results. The image scaling on the Sony X90L is simply excellent. The image is not overly sharpened, which gives a natural effect and makes everything look cohesive. It is evident that the engineers really put effort into this aspect, creating a solution that impresses and works well in everyday use. Because of this, even when watching content like regular television or YouTube, where the image is not inherently stunning, one can enjoy a smooth, cohesive, and visually pleasing experience.

The TCL C655 PRO TV is equipped with a 4K panel with a refresh rate of 60 Hz, making it ideal for watching movies. Additionally, the "Flicker Reduction" feature allows users to adjust the fluidity of the image, giving them the choice between smoother motion or a cinematic, choppy effect. Moreover, the TV handles lower resolution content well, such as Full HD and 2K, offering a refresh rate of 120 Hz, which will certainly appeal to gamers who can enjoy smoother images, albeit at the cost of lower resolution.

Sony X90L with a 120 Hz panel is a great choice for both gamers and movie enthusiasts. The TV is equipped with the Motion Flow smoothness feature, which allows you to adjust motion smoothness using two sliders: "smoothness" and "clarity." The "smoothness" slider controls the level of motion fluidity, which helps reduce image stuttering, while "clarity" is used to reduce blurring and improve motion sharpness, which is especially useful in dynamic scenes.

The TCL C655 PRO television offers an almost perfect set of features for gamers, supporting all key technologies that significantly improve the gaming experience. The ALLM feature automatically switches the television to low latency mode, resulting in better responsiveness and minimized signal delays – particularly important in dynamic titles. VRR synchronizes 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 game mode allows for more detailed color and contrast reproduction in games that support this format, while the Game Bar provides quick access to important settings such as response time or latency level. Unfortunately, this model does not support 4K resolution at 120 Hz, which may disappoint the most demanding gamers. However, for those who can forgo 4K, support for Full HD and 2K at 120 Hz offers exceptionally smooth visuals, making it an attractive alternative for enthusiasts of higher refresh rates.

Sony X90L is a television that performs well in terms of compatibility with consoles and features for gamers. Its 120 Hz panel and two HDMI 2.1 ports with a bandwidth of 48 Gb/s allow for smooth play in high resolution and at a high frame rate. Gamers can also take advantage of the ALLM feature, which automatically switches the TV to low latency mode, and VRR, which provides smooth gameplay without screen tearing. Game Bar is an additional advantage – an intuitive tool that allows for quick access to the most important settings and gaming features, making it easier to control gameplay.

Unfortunately, in terms of HDR in games, the Sony X90L has its limitations. There is no support for HGiG, a standard that many gamers consider essential for precise HDR reproduction in games. Although the TV supports Dolby Vision, which theoretically could improve image quality in games, the practical application of this feature is problematic. Dolby Vision in game mode is associated with very high input lag, making gameplay less comfortable and precise movements more difficult. Additionally, it is not possible to enable Dolby Vision along with VRR. This means that despite numerous advantages, gamers seeking perfect HDR in games may feel a sense of disappointment.

The TCL C655 PRO TV offers an exceptional response time across all supported resolutions and frequencies. Particularly noteworthy is its support for Dolby Vision with a response time of 13 ms, which is rarely found among competitors. As a result, gamers can enjoy remarkable responsiveness even while using advanced HDR effects, significantly enhancing the gaming experience.

The input lag on the Sony X90L can be rated as decent, although it is not exceptional. In Dolby Vision mode, the television operates only at 60 Hz, and the high input lag complicates matters as it makes gameplay practically unplayable. For games at the popular 60 Hz frequency, the input lag is around 25 ms – this is an acceptable result, but for more demanding players, it may be disappointing.

However, those more advanced players who have equipment that supports higher refresh rates can expect better results. With a 120 Hz signal, the input lag drops to around 12 ms, providing significantly better responsiveness and smoother gameplay, meeting the expectations of more demanding users.

Cooperation with the PC on the TCL C655 Pro television is quite good, especially due to the support for chroma 4:4:4, which ensures good readability of fonts. This is an important advantage if the television is to be used as a monitor for office work, where text display accuracy is crucial. Additionally, low input lag provides smooth operation, which will be appreciated by both gamers and users who require a quick response to mouse or keyboard movements.

One of the minor drawbacks that can be noticed is the fact that vertical lines sometimes exhibit a pixel dropout. This causes letters to appear slightly broken, which in certain situations may slightly reduce work comfort, although overall this issue should not be very bothersome for less demanding users. The television does not support 120Hz for its maximum resolution, hence the lower rating compared to higher models. However, TCL has ensured that users can enjoy smooth gameplay at 120Hz at lower resolutions such as 2K and Full HD.

Cooperation with the PC in Sony X90L is at a good level. The X90L TV supports 4:4:4 chroma, which provides quite good font visibility, important when working or browsing content on a large screen. Although there are minimal issues with font readability on a dark background, it is not bothersome enough to be a significant problem in everyday use.

An additional advantage for PC users is the 120 Hz refresh rate and support for G-Sync functionality. As a result, gamers can expect smoother gameplay without stuttering or tearing effects, significantly enhancing comfort and gaming experience.

The viewing angles in the TCL C655 PRO, as with VA panels, are quite limited. Compared to IPS panels, which maintain image quality regardless of the viewing angle, the VA panel in this model quickly loses contrast and color saturation even with a slight deviation from the axis. Watching at an angle causes black to become more gray, and colors lose their depth and intensity. For this reason, the TV is better suited for rooms where viewing occurs mainly straight on. It is not a television that is an ideal choice for large spaces where viewers may be seated at different angles.

Viewing angles on the Sony X90L are unfortunately very poor, which is typical for VA panels. The picture loses quality when viewed from an angle, which can be problematic when watching from a greater distance or with a larger group of people. It's a pity that the manufacturer did not apply a coating to widen the viewing angles, which could significantly improve this aspect and make the TV more versatile for different room layouts.

TCL C655 PRO offers quite decent brightness, reaching around 520 nits, which makes using the television during the day comfortable. This brightness allows for good image visibility even in rooms with more sunlight. Although the television performs well in such conditions, the satin finish of the display has only average capabilities in suppressing reflections. In very bright environments, reflections may appear, which slightly worsen the visibility of the image, especially in scenes with lower contrast.

The performance of the Sony X90L television during the day is at a very good level. The matte screen effectively suppresses reflections, which minimizes glare and keeps the image clear even in bright rooms. The SDR brightness of 785 cd/m² allows for comfortable viewing of standard television and lower quality materials regardless of the time of day. As a result, the X90L performs excellently in both well-lit living rooms and more sunlit spaces.

The TCL C655 PRO TV operates on the Google TV system, which is an extension of the popular Android TV. Google TV offers personalized content recommendations based on viewed materials and user preferences, providing easy access to movies, series, and apps. Thanks to its clear interface, navigation is simple, and access to popular streaming apps such as Netflix, YouTube, Prime Video, and Disney+ allows enjoying a wide range of content. The system also supports integration with the Google ecosystem, enabling control of the TV using voice commands with Google Assistant and synchronization with other smart home devices.

The TCL C655 PRO offers additional features that enhance usability, such as support for Apple AirPlay, allowing for quick content streaming from Apple devices directly to the TV screen. Additionally, the ability to connect peripherals via Bluetooth – e.g., keyboards, mice, or headphones – makes usage even more convenient. Unfortunately, this model does not have the functionality to record content to USB or the picture-in-picture (PiP) option, which may be a disappointment for those accustomed to these conveniences in traditional television. Nevertheless, the TCL C655 PRO offers many modern solutions that facilitate daily entertainment.

The design of the TCL C655 PRO TV appears modern, with elegant and slim metallic bezels that add sturdiness and aesthetic appeal to the device. Overall, it looks very good and will certainly fit into most interiors. Although the bezels are minimalist, the TV itself is not among the thinnest on the market, especially compared to Korean competitors who often offer even slimmer designs.

Sony X90L offers a rich set of features, starting with the Google TV system, which is the heart of entertainment. This solution provides access to a huge amount of apps and streaming services, and the interface is intuitive and clear. With voice assistant support, using the TV becomes even more convenient – just one command is enough to find your favorite movies, series, or music. Google TV operates smoothly and allows for full customization, making daily use enjoyable and hassle-free.

The TV also offers a range of practical features. It supports AirPlay and Miracast, making it easy to stream content from mobile devices. Additionally, other devices can be connected via Bluetooth, enhancing versatility and ease of use. For those who prefer traditional television viewing, there is even a recording function available without the need for an external decoder, which is a big advantage for fans of live shows.

In terms of design, Sony X90L may not be the sleekest, but its appearance is impressive thanks to the metal frame, which adds elegance. The TV is equipped with a stand that can be set up in three different ways, allowing it to be adjusted to various spaces and user preferences.

Thanks to the built-in player, the television is capable of playing most file formats available on external storage, making it a versatile tool for consuming multimedia. However, there may be certain limitations in supporting some formats, which can be inconvenient for more demanding users. Fortunately, the Google TV system allows the installation of other media players from Google Play, enabling the elimination of compatibility issues. This gives users the opportunity to choose applications that best meet their needs, significantly enhancing the functionality of the television.

Sony X90L easily handles playback of most popular file formats from USB, which is a big plus for those who frequently access external content. However, it is worth mentioning a slight downside – the built-in player does not allow for changing the font color in subtitles, which can be problematic for some. Fortunately, thanks to the advanced Google TV system, users have a wide range of options. It is easy to install alternative media players that offer more personalization options.

The sound on the TCL C655 PRO television is quite good, thanks to the 2x15W audio system supported by a 20W subwoofer branded by Onkyo. As a result, the sound is fuller, and the bass is deeper, positively impacting the overall sound quality. However, one should not get overly enthusiastic – the television cannot replace a dedicated soundbar, especially for more demanding users expecting cinema-quality audio.

The sound in Sony X90L is pleasant and clear, and the presence of bass makes the sound fuller. The TV performs well in playing music, offering satisfying audio experiences. An additional advantage is the support for Dolby Atmos and DTS technologies, which provide a more spatial and immersive sound. As a result, movies, games, and music gain depth and realism, creating a better experience for the user.
