Compare: TCL C655 Pro vs LG QNED91T6A

TCL C655 PRO is an extension of the basic model in this series, and although the name may suggest only slight differences, the addition of "PRO" truly means a lot here. The biggest change compared to its less advanced sibling is the picture quality. The manufacturer decided to implement local dimming technology, which significantly improves black levels and contrast. The TV is able to offer us a more refined picture. Thanks to this, TCL C655 PRO clearly outperforms the more basic version in this regard. The applied QLED panel further enhances the coverage of a wide color gamut, offering vibrant and saturated colors, which works brilliantly in both movies and dynamic content like 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 gameplay comfort. The TV can also adjust the screen refresh rate to a lower resolution, meaning that despite support for 4K at 60 Hz, in Full HD or 2K you can enjoy a smoother picture thanks to 120 Hz. In everyday use, the Google TV operating system performs excellently. The intuitive interface, personalized recommendations, and wide access to streaming apps like Netflix, YouTube, and Disney+ make the TV enjoyable to use. Because of this, we easily forgive the lack of recording and picture-in-picture (PiP) features, which doesn’t pose a significant problem given the rich app offerings. If we are able to stretch that slight price difference, we definitely recommend the TCL C655 in the PRO version.

LG QNED91T is the only MiniLED-backlit TV from LG for 2024 that catches the eye with its innovative use of a VA panel. This is certainly a departure from the established standards of the Korean manufacturer with its top-tier LCD TVs, which typically used an IPS/ADS panel. But the result is positive – the panel combined with local dimming offers really good contrast. Blacks are deep and should satisfy most users. LG 65QNED91T6A is a very bright TV, so placing it in slightly challenging lighting conditions will not pose a challenge for it. In terms of motion fluidity, the QNED91T shows top class. The TruMotion feature works great, allowing for image adjustment according to personal preferences – from a classic, cinematic look to a more fluid effect. And the 120Hz panel makes it ideal 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 for features like VRR and ALLM (and more). This, combined with low input lag, makes this equipment an excellent choice for gaming on a console or PC. Daily use of QNED91T is pure pleasure, mainly thanks to the WebOS system. The interface is intuitive, there's no lack of applications, and the Magic Remote included in the package significantly simplifies navigation through the menu. Operation is fast, and using the TV is comfortable thanks to the voice assistant. Unfortunately, the TV also has its weaknesses. 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 very well. In HDR content, there are situations where the picture is either too bright or excessively dark, which is particularly problematic in scenes requiring precision. Additionally - in practice, the differences between standard HDR10 and Dolby Vision are nearly invisible. This is a significant disappointment, especially in this class of TV. Nonetheless, the LG QNED91T is an interesting choice for those who need a TV with high brightness, considerable gaming capabilities, and appreciate the convenience of the WebOS system. If the priority is picture quality in HDR content, such as Netflix, Prime Video, or Max, we recommend considering alternative models, such as OLED B4 from the 2024 line, which is available for a similar price.

The TCL 655 PRO TV, equipped with a VA panel, provides solid contrast; however, the key role in improving image quality here is played by local dimming technology. The tested 55-inch variant has 84 backlight zones, which significantly enhance the contrast compared to the model without the "PRO" suffix, and this effect is clearly visible in the first three tested scenes. It is worth noting that larger versions of this TV naturally have more zones, which translates to even better contrast. Of course, as with any LCD TV, certain shortcomings remain – particularly noticeable on tested screens 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 big impression and stands out well in the categories of black and contrast.

QNED91T is a television with MiniLED backlighting, and in the tested size of 65", we counted 160 local dimming zones. The unit we tested, with a "1" at the end, is equipped with a VA panel, which offers significantly better contrast than IPS panels, which - note - can be found in the model LG QNED90T. Therefore, it's wise to be cautious when choosing a version to avoid disappointment regarding contrast. The model QNED90T is rather hard 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 of the scenes from the movie "Oblivion," we observed perfect separation of lights - it looked impressive. However, not everything is so straightforward. In a scene from "Sicario 2," we noticed that the screen was noticeably darker, deviating significantly 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 considerable one at that. Despite these compromises, the contrast of LG 65QNED91T6A is genuinely solid. Of course, as is the case with MiniLED televisions, some limitations must be taken into account, but the overall impression is very positive.

In the HDR effect quality category, the television TCL 655 PRO shows decent capabilities, achieving 550 nits of peak brightness. This allows for enjoying HDR effects, which can be clearly seen in scenes such as the first one from the movie Life of Pi or the final shot from The Meg. However, 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 more. The dimming algorithm aims for deep blacks, but at the cost of brightness – which at those moments can cause a drop in brightness of even half. In these more challenging scenes with small elements, it's hard to find any praise, and the HDR effect resembles SDR. Nevertheless, the coverage of the colour palette deserves recognition, which, like in the version without the PRO suffix, is at a very good level.

As befits a MiniLED television, LG QNED91T easily exceeds the magical barrier of 1000 nits on the luminance chart. In scenes where light played a key role, the effect was truly commendable. For instance, 1000 nits in the first scene of "Life of Pi" is a really impressive value, and the achieved 600 nits in the third and fifth scenes allowed for a true sense of HDR magic. However, problems arise with very small light elements on the screen, such as the moon, street lamps, or lights. Values around 100 nits - to put it bluntly - are disappointing, as these elements are so dark they are 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 halo effect, do impact the brightness of smaller elements.

Each of our TV tests is conducted in movie mode, which usually offers the best colour reproduction. However, even this mode is not free from issues, as we noted in 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 overly emphasise the colour blue. As a result, the image can give a sense of artificial sharpness, which proves to be uncomfortable for the eyes over a longer period. The brightness characteristics also leave much to be desired. The Gamma chart indicates serious difficulties with excessive brightening, making the overall presentation appear washed out. Additionally, the EOTF curve reveals significant problems with reproducing very small elements – they are overly dimmed, as we have detailed in the paragraph regarding HDR effects.

All our tests are conducted in the best picture mode on each television. In this case, as usual, it’s the Filmmaker mode. The name of the mode suggests ideal colour reproduction; however, there were noticeable deviations from the correct image. Our unit, in terms of white balance, exhibited a significant drop in blue hues - both in SDR and 4K HDR materials - resulting in a noticeable yellowing of the image, evident in the comparison scenes from a movie with Tom Cruise. As we described earlier, QNED91T has a tendency to brighten the screen. This is confirmed by the gamma, which is quite significantly lower than the reference value of 2.4. Meanwhile, the EOTF curve, which is responsible for brightness in 4K content, showed some issues with the television’s ability to dim the image in the darkest areas, which we could observe in the paragraph describing the quality of the HDR effect. Although the Filmmaker mode is a pretty good "out of the box" mode, it still requires some adjustments.

After calibrating the TCL 655 PRO television, there is a noticeable improvement in white balance, where the tendency for the screen to be overly pink has been completely eliminated, which was previously noticeable in factory mode. The picture has taken on more natural tones, especially in white and bright elements, which positively affects the overall image perception. Regarding brightness characteristics, the Gamma chart has also improved – the screen is no longer excessively bright, which previously made the image appear washed out. Nevertheless, there are still some issues with the EOTF curve, which are difficult to eliminate due to the television's construction and its limited number of backlight zones. These limitations prevent achieving perfect results in this regard. However, despite this minor fault, 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 took advantage of. When it comes to white balance, we managed to significantly correct it in SDR content. The picture mode in 4K HDR quality posed greater challenges, which, while still not perfect, looks significantly better than before calibration. The errors on the Color Checker palette and the colour palette are much smaller than in the factory settings. In terms of brightness characteristics, gamma for HD content is practically perfect, with a small exception at the end of the graph. However, the biggest issues the television faced were with brightness in 4K HDR content. Analyzing the EOTF characteristics in films, we noticed that the television manipulates brightness quite a bit, which we could observe in previous tests. Brightness is significantly boosted compared to the graph in the static test, and the television brightens certain scenes to the extent that some smaller details lose definition. Unfortunately, this is caused by an average backlight zone management algorithm in this model. Nevertheless, the calibration yields quite good results, especially regarding accurate colour reproduction.

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 LG QNED91T looks very good. There are only slight cutoffs in the brightest scenes, but the television handles blacks very well, providing smooth tonal transitions. As a result, the image is natural and pleasant to the eye, with no visible issues.

The TCL 655 PRO television handles tonal transitions quite well in lower-quality material. The "Gradual Smoothing" feature at low settings effectively smooths tonal transitions, but this comes at the cost of losing some essential details, such as the texture of objects. On the plus side, it doesn't negatively affect film grain, which helps maintain a natural look to the image.

In the context of digital processing, the television adds artificial sharpness. This may appeal to users who prefer a bolder image. However, individuals who favour a softer, more subtle look may find this a drawback. Additionally, a downside is the image cropping due to overscan, which limits the field of view and cuts off 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 TVs - "Smooth Gradation". We can control it at three levels: low, medium, and high. We recommend using the medium option, as it handles tonal transitions well without causing noticeable issues with removing the structure of objects or other artifacts.

On the other hand, when it comes to image scaling (upscaling), LG's Alpha processor performs quite well here. The image appears very smooth, with slight jaggedness in some elements, but this does not significantly affect quality. It looks really good, and the overall effect is very satisfying.

The TCL C655 PRO television is equipped with a 4K display with a refresh rate of 60 Hz, making it ideal for watching movies. Additionally, the "Flicker Reduction" feature allows for adjusting the smoothness of the picture, giving the user the choice between smoother motion and a cinematic, frame-by-frame effect. Furthermore, the television performs well with lower resolution content, such as Full HD and 2K, offering a refresh rate of 120 Hz, which will surely appeal to gamers who can enjoy a smoother image, albeit at the cost 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 TruMotion technology, which allows for smoother image display in films. With this feature, we can adjust the "De-Judder" and "De-Blur" sliders. The "De-Judder" slider reduces stutter in films, which is particularly useful when playing content with a lower frame rate, while "De-Blur" helps to reduce motion blur in fast scenes, which is important for sports or dynamic shots.

The TCL C655 PRO TV offers an almost perfect set of features for gamers, supporting all key technologies that significantly enhance gameplay comfort. The ALLM feature automatically switches the TV to low-latency mode, improving responsiveness and minimising signal delay – particularly important in fast-paced titles. VRR synchronises the screen refresh rate with the frame rate generated by the console, eliminating screen tearing and ensuring smoother gameplay.

Support for Dolby Vision in game mode enables more detailed colour and contrast representation 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 offers exceptionally smooth visuals, making it an attractive alternative for high refresh rate enthusiasts.

The LG 65QNED91T6A television is equipped with HDMI 2.1 ports with a 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 gaming, such as HGiG and Dolby Vision, we can fully utilise the potential of the PS5 and XBOX One consoles. The television also easily handles lower resolutions than 4K, so even older consoles look good on it. The Game Bar makes it easier to access gaming-related settings, allowing us to quickly and intuitively adjust picture parameters and features for gamers. Additionally, the QNED91T offers NVIDIA GeForce Now functionality, allowing us to play in the cloud without needing a console. However, it's important to keep in mind that this solution is quite costly and somewhat falls behind the Xbox Game Pass, which is available only on Samsung televisions.

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

The TCL C655 PRO TV offers exceptional response times across all supported resolutions and refresh rates. Notably, it supports Dolby Vision with a response time of 13ms, which is rare among competitors. This allows gamers to enjoy excellent responsiveness even when using advanced HDR effects, significantly enhancing the gaming experience.

Input lag on QNED91T is really very low, even in Dolby Vision mode. This means we can expect a quick response time, which is very important in fast-paced 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 PC on the TCL C655 Pro TV works quite well, especially thanks to the support for chroma 4:4:4, which ensures good readability of fonts. This is an important advantage if the TV is to be used as a monitor for office work, where precision in displaying text is crucial. Additionally, the low input lag provides smooth performance, which will be appreciated by both gamers and users who need a quick response to mouse or keyboard movements.

One of the minor drawbacks that can be noticed is the fact that in vertical lines, there is occasionally a one-pixel blackout. This can make letters appear slightly broken, which in certain situations might lower work comfort a bit, although generally, this issue should not be very bothersome for less demanding users. The TV does not support 120Hz for its maximum resolution, hence the lower rating compared to higher models. However, TCL has ensured that you can enjoy smooth gameplay at 120Hz in lower resolutions such as 2K and FullHD.

When it comes to gaming on a computer, LG QNED91T synchronises effortlessly with NVIDIA graphics cards and supports G-Sync functionality. The very low input lag makes gaming with a personal computer a real joy. The TV supports chroma 4:4:4, which provides excellent text readability. While we did notice 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 with a VA panel, are quite limited. Compared to IPS panels, which maintain image quality better regardless of the viewing angle, the VA panel in this model quickly loses contrast and colour saturation with just a slight deviation from the axis. Watching at an angle causes blacks to appear more grey, and colours lose their depth and intensity. For this reason, the television 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 sitting 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, which is also evident in the case of QNED91T LG. The viewing angles here are not the best, and while the use of an angle-enhancing coating could significantly improve the situation, unfortunately, we don’t have that here. As a result, the picture loses quality when viewed from a greater angle, which can be problematic when more people are watching at the same time.

TCL C655 PRO offers quite decent brightness, reaching around 520 nits, which makes using the TV during the day comfortable. This brightness allows for good image visibility even in rooms with higher sunlight exposure. Although the TV performs well in such conditions, the satin finish of the panel has only average capabilities for reducing reflections. In very bright environments, reflections may occur that somewhat impair image visibility, especially in scenes with lower contrast.

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

The TCL C655 PRO television runs on the Google TV system, which is an extension of the popular Android TV. Google TV provides personalised content recommendations based on viewed materials and user preferences, granting easy access to movies, series, and applications. With a clear interface, navigation is simple, and access to popular streaming apps like Netflix, YouTube, Prime Video, and Disney+ allows enjoyment of a wide range of content. The system also supports integration with the Google ecosystem, enabling control of the television via voice commands using Google Assistant and synchronisation with other smart home devices.

The TCL C655 PRO offers additional features that enhance user comfort, such as support for Apple AirPlay, allowing quick streaming of content from Apple devices directly to the TV screen. Additionally, the ability to connect peripherals via Bluetooth – such as keyboards, mice, or headphones – makes usage even more convenient. Unfortunately, this model does not have a USB recording feature or a 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 television presents a modern look, with elegant and slim metal bezels that add solidity and aesthetic appeal to the device. The overall appearance is very good and will certainly fit into most interiors. Although the bezels are minimalist, the television itself is not among the thinnest on the market, especially compared to Korean competitors who often provide even sleeker designs.

The most important thing in today's televisions, apart from picture quality, is the operating system. The one available in LG models is really very good. Of course, we're talking about the WebOS system, which offers most of the popular apps available in Poland, much like 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 features, the television offers practically everything one could wish for. Here we find the ability to record programs 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 handy Magic Remote. Unfortunately, the PiP (Picture-in-Picture) feature is missing here, but it's such a specific function that only those who really 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 drives, making it a versatile tool for consuming multimedia. However, there may be some limitations in supporting certain formats, which can be annoying for more demanding users. Fortunately, the Google TV system allows for the installation of other media players from Google Play, which helps eliminate compatibility issues. As a result, users have the option to choose applications that best meet their needs, significantly increasing the functionality of the television.

The built-in player in QNED91T should satisfy most users. It handles Polish characters without issue and plays movies with subtitles from external drives. The player also manages most audio formats and photos, 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 fuller sound and deeper bass, which positively impacts the overall audio quality. However, one should not become overly enthusiastic – the television cannot replace a dedicated soundbar, especially for more demanding users expecting cinema-quality audio.

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