Compare: TCL C655 Pro vs LG QNED91T6A

TCL C655 PRO is an upgrade of the basic model from this series, and although the name may suggest only minor differences, the addition of "PRO" truly signifies much more. The biggest change, compared to its less advanced sibling, is the picture quality. The manufacturer has opted for the implementation of local dimming technology, which significantly improves black levels and contrast. The television is able to offer us a more refined image. As a result, TCL C655 PRO clearly outshines the more basic version in this regard. The applied QLED panel further enhances the coverage of a wide colour range, offering vibrant and saturated colours, which excel in both films and dynamic content, such as games. In the context of gaming, just like the basic version, TCL C655 PRO offers a host 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 a lower resolution, meaning that despite supporting 4K at 60 Hz, in Full HD or 2K, one can enjoy smoother images at 120 Hz. In daily use, the Google TV operating system works excellently. The intuitive interface, personalised recommendations, and broad access to streaming applications, such as Netflix, YouTube, or Disney+, make the television enjoyable to use. This makes it easy to overlook the lack of recording functionality and picture-in-picture (PiP), which is not a major issue given the rich offering of applications. If we are willing to make that slight price difference, we definitely recommend TCL C655 in the PRO version.

LG QNED91T is the only MiniLED backlit television from LG for 2024, attracting attention due to its innovative use of a VA panel. This is a certain departure from the previous standards of the Korean manufacturer in its top LCD televisions, which usually featured an IPS/ADS panel. However, the effect is positive – the panel combined with local dimming offers really good contrast. The blacks are deep and should satisfy most users. LG 65QNED91T6A is truly a bright television, so placing it in somewhat challenging lighting conditions will not pose a challenge for it. In terms of motion fluidity, the QNED91T shows top class. The TruMotion feature works excellently, allowing for adjustment of the image to personal preferences – from classic, cinematic looks to a smoother effect. And the 120Hz panel makes it ideal equipment for sports or gaming. For the latter, LG has prepared something special – four full HDMI 2.1 ports with a bandwidth of 48 Gbps, allowing you to enjoy features like VRR and ALLM (among others). This, combined with low input lag, makes this equipment an excellent choice for gaming on console or PC. Everyday use of QNED91T is pure pleasure, mainly thanks to the WebOS system. The interface is intuitive, there are plenty of applications available, and the included Magic Remote control significantly facilitates navigation through the menu. The operation is quick, and using the television is comfortable thanks to the voice assistant. Unfortunately, the television also has its drawbacks. Despite the advantages of the VA panel in terms of high contrast, the algorithms responsible for local dimming of the miniLED zones do not perform their best. In HDR content, there are situations where the image is either too bright or excessively dark, which is particularly troublesome in scenes requiring precision. Additionally, in practice, the differences between standard HDR10 and Dolby Vision are almost imperceptible. This is a significant disappointment, especially in this class of television. Nevertheless, the LG QNED91T is an interesting choice for those who need a high-brightness television with considerable gaming capabilities and value the convenience of the WebOS system. If image quality in HDR content, such as Netflix, Prime Video, or Max, is a priority, we recommend considering alternative models, for example, OLED B4 from the 2024 line, which can be purchased for a similar price.

The TCL 655 PRO television, equipped with a VA panel, delivers solid contrast; however, the key role in enhancing image quality is played by local dimming technology. The tested 55-inch variant features 84 backlight zones, which significantly improve contrast compared to the model without the "PRO" designation, and this effect is distinctly visible in the first three tested scenes. It is worth noting that larger versions of this television naturally have more zones, which translates to even better contrast. Of course, as with any LCD television, certain imperfections remain – particularly noticeable in the tested scenes 4 and 5, where smaller bright elements lose a lot of quality. Nevertheless, considering the price of the device, the TCL 655 PRO makes a strong impression and stands out well in the black and contrast category.

QNED91T is a television with MiniLED backlighting, and in the tested size of 65", we noted 160 zones of backlighting. The specimen we tested, with the "1" suffix at the end, was equipped with a VA panel, which offers significantly better contrast than IPS panels, which - note - can be found in the LG QNED90T. Therefore, it is worth being cautious when choosing a version to avoid disappointment in terms of contrast. The model QNED90T is rather difficult to acquire in Poland, but distribution can vary. Returning to our contrast tests, it performed really well in less demanding scenes. For example, in one scene from the film "Oblivion", we observed perfect light separation - it looked impressive. However, not everything is so straightforward. In a scene from "Sicario 2", we noticed that the screen was noticeably darker, significantly deviating from the reference image appearance. The television effectively eliminates the halo effect (i.e., the glow around objects), but this comes at the cost of brightness - and quite a substantial one. Despite these compromises, the contrast of the LG 65QNED91T6A is really solid. Of course, as is the case with MiniLED televisions, one must reckon with certain limitations, but the overall impressions are very positive.

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.

As befits a MiniLED television, LG QNED91T easily surpasses the magical barrier of 1000 nits on the luminance chart. In scenes where light played a key role, the effect was truly decent. For instance, 1000 nits in the first scene of "Life of Pi" is an impressive value, and the 600 nits achieved in the third and fifth scenes allowed one to feel the true magic of HDR. However, problems arise with very small light elements on the screen, such as the moon, street lamps, or lights. A value around 100 nits - to put it bluntly - is disappointing, as these elements are dark enough to be barely visible. The television deserves praise for covering 96% of the DCI-P3 colour gamut and 75% of BT.2020. LG QNED91T leaves us with very mixed feelings, mainly due to the very aggressive dimming algorithms, which, while effectively eliminating the halo effect, negatively impact the brightness of smaller elements.

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.

All our tests are conducted in the best picture mode on each television. In this case, as usual, it is the Filmmaker mode. The name of the mode suggests ideal colour reproduction; however, there were noticeable deviations from the correct image here. Our unit, in terms of white balance, displayed quite a strong dip in blue hues - both in SDR and 4K HDR content - which resulted in a distinct yellowing of the image, visible in comparison scenes from the film with Tom Cruise. As we mentioned earlier, QNED91T has certain tendencies to brighten the screen. This is confirmed by gamma, which is quite significantly below the reference value of 2.4. Meanwhile, the EOTF curve, responsible for brightness in 4K content, showed some issues with the television's dimming in the darkest areas, which we could observe in the paragraph describing the quality of the HDR effect. Although the Filmmaker mode is quite a good "out-of-the-box" mode, it too requires some adjustments.

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.

LG offers advanced calibration tools in its televisions such as 65QNED91T6A, which we utilised. When it comes to white balance, we were able to significantly correct it in SDR content. The picture mode in 4K HDR quality posed greater challenges, which, although still not perfect, looks significantly better than before calibration. Errors on the Color Checker palette and colour gamut are much smaller than in the factory settings. Regarding brightness characteristics, gamma for HD content is practically ideal, with a slight exception at the end of the graph. However, the television had the most trouble with brightness in 4K HDR content. Analyzing the EOTF characteristics in films, we observed that the television manipulates brightness quite heavily, which we could see in previous tests. Brightness is significantly boosted compared to the graph in the static test, and the television lights up certain scenes to the point that some smaller elements lose detail. This is unfortunately caused by the average backlight zone management algorithm in this model. Nevertheless, calibration yields quite good results, especially when it comes to the precise reproduction of colours.

The tonal transitions are really quite good and would deserve a high rating (8), however, the score has been clearly lowered for another reason - the image is artificially sharpened despite the "sharpness" setting being at 0. As a result, the image is unpleasant to look at.

The gradation on the LG QNED91T looks very good. There are only slight cut-offs in the brightest scenes, but the television handles the black levels very well, ensuring smooth tonal transitions. As a result, the picture is natural and pleasant to the eye, without any visible issues.

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.

When it comes to tonal transitions in lower quality materials, the television offers a well-known feature from LG televisions - "Smooth Gradation". We can control it in three levels: low, medium, and high. We recommend using the medium option, as it does a good job of removing tonal transitions without causing noticeable problems with the removal of object structure or other artefacts.

As for image scaling (upscaling), LG's Alpha processor performs quite well in this regard. The image appears very plastic, with slight aliasing on some elements, which does not significantly affect the quality. It looks really okay, and the overall effect is very satisfactory.

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.

The television has a refresh rate of 120 Hz, which should satisfy most users in terms of motion smoothness. Additionally, QNED91T is equipped with the TruMotion feature, which allows for smoother image display in films. Within this feature, we can adjust the "De-Judder" and "De-Blur" sliders. The "De-Judder" slider is responsible for reducing judder in films, which is particularly useful when playing content with a lower frame rate, while "De-Blur" helps to reduce blur in fast scenes, which is important for sports or dynamic shots.

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.

The LG 65QNED91T6A television is equipped with HDMI 2.1 ports with full bandwidth of 48 Gb/s, providing full support for all the standards needed for gaming on modern consoles. We can count on variable refresh rate (VRR) support and automatic low latency mode (ALLM). This ensures smooth gameplay without delays.

Thanks to support for all popular HDR standards in games, such as HGiG and Dolby Vision, we can fully utilise the potential of the PS5 and XBOX One consoles. The television also handles lower resolutions than 4K without any issues, so even older consoles look good on it. The Game Bar makes it easy to access gaming-related settings, allowing us to quickly and intuitively adjust picture parameters and features for gamers. Additionally, the QNED91T offers the NVIDIA GeForce Now feature, which allows us to play in the cloud without needing a console. However, it should be noted that this solution is quite costly and somewhat falls short of the Xbox Game Pass, which is available only on Samsung televisions.

QNED91T LG is an excellent choice for both less experienced and more advanced gamers looking for a versatile television for gaming.

The TCL C655 PRO television offers exceptional response times across all supported resolutions and refresh rates. Notably, it supports Dolby Vision with a response time of 13 ms, which is rarely seen in the competition. As a result, gamers can enjoy outstanding responsiveness even when using advanced HDR effects, significantly enhancing the gaming experience.

The input lag on QNED91T is really very low, even in Dolby Vision mode. This means we can rely on a fast response time, which is very important in dynamic games where every millisecond counts. Regardless of whether we are playing in standard mode or HDR, the television offers very good results that will satisfy even the most demanding gamers.

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

One minor flaw that can be noticed is the fact that in vertical lines, there is sometimes a drop of one pixel. This can make letters appear slightly interrupted, which in certain situations may somewhat reduce work comfort, although generally, this issue should not be very bothersome for less demanding users. The television does not support 120Hz at its maximum resolution, hence a 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 FullHD.

When it comes to gaming on a computer, LG QNED91T easily synchronises with NVIDIA graphics cards and supports G-Sync functionality. The very low input lag makes gaming on a personal computer truly enjoyable. The television supports chroma 4:4:4, which provides excellent text readability. Although we noticed slight blurring of fonts around the edges, overall the image looks very good, and readability is at an acceptable level.

The viewing angles on the TCL C655 PRO, as is typical for 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 colour saturation, even with a slight deviation from the axis. Watching at an angle causes blacks to appear greyer, while colours lose their depth and intensity. For this reason, the television is better suited for rooms where viewing takes place mainly straight on. It is not a television that is an ideal choice for large spaces where viewers may be seated at various angles.

As we mentioned in the paragraph about contrast, the television is equipped with a VA panel, which generally offers very good contrast compared to IPS panels. Unfortunately, VA panels have their weakness in the form of limited viewing angles, a weakness that is also evident in the case of QNED91T LG. The viewing angles here are not the best, and although the use of an angle-expanding coating could significantly improve the situation, unfortunately, it is not present here. As a result, the picture loses quality when viewed from a larger angle, which can be problematic when there are multiple people watching at the same time.

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

The LG 65QNED91T6A television is equipped with a satin panel, which performs moderately with direct reflections of light, such as from lamps or wall lights. In the first test photo with a large lamp, you can see how the reflection "spreads across the screen". However, the QNED91T makes up for this in terms of brightness - the average SDR brightness of 580 cd/m² is sufficient for watching television even in more challenging lighting conditions. As a result, despite the issues with reflections, the television performs well during the day.

The TCL C655 PRO television operates on Google TV, which is an extension of the popular Android TV. Google TV offers personalised content recommendations based on viewed materials and user preferences, providing easy access to films, series, and applications. With its clear interface, navigation is straightforward, and access to the most popular streaming applications, such as Netflix, YouTube, Prime Video, and Disney+, allows for enjoyment of a wide range of content. The system also supports integration with the Google ecosystem, enabling control of the television using voice commands with Google Assistant and synchronisation with other smart home devices.

TCL C655 PRO offers additional features that enhance user comfort, such as support for Apple AirPlay, allowing for quick content streaming from Apple devices directly to the television screen. Furthermore, 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 function to record content on 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 everyday entertainment.

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

The most important thing in today's televisions, besides picture quality, is the operating system. The one available in LG models is really very good. Of course, we are talking about the WebOS system, which offers most of the popular applications available in Poland, similar to GoogleTV. What sets this system apart is primarily the excellent remote control with an accelerometer - the Magic Remote, which resembles a magic wand. Controlling with this remote is incredibly convenient. Additionally, the television offers a very good voice assistant that understands Polish perfectly.

In terms of user functions, the television offers practically everything one could desire. Here we find the ability to record programmes from built-in tuners, support for AirPlay to connect an iPhone, and a mirroring function. We can easily connect keyboards, mice, or headphones, although keyboards are not essential thanks to the convenient Magic Remote. Unfortunately, it lacks the PiP (Picture-in-Picture) function, but this is such a specific feature that only those who truly need it will feel its absence. The QNED91T is a television that does not disappoint when it comes to daily enjoyment of its use.

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

The built-in player in QNED91T should satisfy most users. It easily handles Polish characters and plays films with subtitles from external drives. The player will also cope with most audio and photo formats, except for Apple HEIC files.

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. This results in a fuller sound and deeper bass, positively affecting the overall audio quality. However, one should not get overly enthusiastic – the television cannot replace a dedicated soundbar, especially for more demanding users looking for cinema-quality audio.

LG QNED91T is equipped with a set of 4 speakers in a 2.2 configuration with a total power of 40W. The television sounds quite pleasant, and the subtle bass is noticeable. Of course, it is not at the level of an external audio system, such as a soundbar or home cinema, but it is sufficient for everyday use. It is also worth praising the support for audio formats DTS:X and Dolby Atmos, which significantly enhance the quality of sound experiences.
