Compare: TCL MQLED85 / C765 vs LG OLED C4

TCL MQLED85, or model C765, is a television that can truly surprise, especially in this price range. It is one of the cheapest models featuring mini-LED technology, which is immediately evident in the picture quality. The blacks are deep, and the brightness is sufficient even in a brightly lit room. Thanks to the large number of dimming zones, watching movies in the evening is a pleasure – the blacks are really deep, and the picture in dark scenes looks clear. However, it's not perfect – in some scenes, you may notice minor issues with small bright elements, but this is really a minor detail compared to what this model offers. Google TV performs excellently here – there are plenty of apps, and using the system is simply convenient. Voice control in Polish works flawlessly, which can be particularly useful if you don't want to type movie titles using the remote. Of course, there are minor shortcomings, such as the lack of recording capabilities, but these are not things that interfere with daily use. For gamers, it is also a fantastic option. Support for HDMI 2.1, VRR and low input lag means the television handles consoles well and competes effortlessly with more expensive models from Korean or Japanese manufacturers. At this price, it's hard to find something better when it comes to smooth and responsive gameplay. During testing, we encountered a few minor software issues, but it's hard to say whether that's a serious downside. We hope that TCL will release updates, so there’s a chance this issue will be resolved quickly. TCL MQLED85/C765 is an excellent choice if we are looking for a television with good picture quality and modern features at a reasonable price. It is a model that combines affordable mini-LED technology with a convenient Google TV system, and it’s also great for gaming. Minor software shortcomings are something you can live with, especially considering what this television offers in its class.

LG C4 is a television that will likely have no competition in its price range for many users. Thanks to the wide options for purchase, it will appeal to those looking for a TV strictly for movies and series, as well as for gaming. The advanced WebOS system and a remote that works like a mouse will certainly make everyday use much easier and ensure that we will likely stick with this brand for a much longer time. The OLED panel implemented by the manufacturer, resulting from over 10 years of history, shows that it has not yet said its last word. Brightness results in HDR material are very solid and can display an incredibly dynamic and deep image. Here, it’s worth mentioning the excellently implemented dynamic tone mapping feature, which makes HDR10 images look almost as good as Dolby Vision. And if we’re talking about fidelity to artistic vision, we can't forget about how calibratable LG TVs are, allowing for a great deal of freedom for the calibrator and classic calibration for home users, as well as 3D LUT for professionals. However, if we are looking for a gaming TV, then the LG C4, like most of the manufacturer’s OLED TVs, will be the ideal choice. With the implementation of HDMI 2.1 ports and the full use of their potential, we can enjoy extremely smooth gameplay with all the benefits, such as VRR, ALLM, FreeSync, or G-Sync. Of course, the panel, which has a maximum refresh rate of 144 Hz and an advanced smoothing technology, will also allow for very smooth and sharp images during broadcasts of various sporting events. It’s hard not to give a high rating to LG OLED C4, as it's difficult to find a TV in a similar price range with such advanced features among the competition.

TCL MQLED85/C765 stands out due to its use of a VA panel and Mini LED backlighting, which makes a huge difference compared to traditional backlighting systems. Mini LED, with its significantly smaller diodes, allows for more precise control of the screen's backlighting, resulting in much better contrast and deeper blacks. The model with a 55-inch diagonal that we are testing has an impressive number of over 700 local dimming zones, providing exceptional precision in image display. It's worth noting, however, that the number of backlighting zones may vary depending on the screen size – for larger diagonals, the number of zones naturally increases due to the larger screen area, allowing larger sizes to achieve better results in terms of contrast and black levels. Thanks to the enormous number of zones, the TCL MQLED85/C765 achieved results comparable to OLED screens on our first test pattern from the movie "Oblivion," offering nearly reference-level contrast. But what happens when we test this model in even more demanding conditions? How will the TV perform in tougher scenarios? Overall, the TCL MQLED85/C765 performs very well with black levels, but in some cases, the local dimming algorithm is not perfect. On dark backgrounds, smaller bright elements can lose clarity and brightness, as confirmed by our latest pattern from the Pioneer Kuro test disc. Despite some imperfections in the local dimming algorithm, and thus a slight occurrence of the HALO effect (which is a bright halo around bright objects on a dark background caused by deficiencies in the screen's local dimming), the results achieved by the TCL MQLED85/C765 are impressive, especially considering its price. This TV offers contrast and black depth that can compete with models that are even twice as expensive.

LG OLED C4, as the name suggests, uses an organic panel of its own production. This series definitely belongs to one of the most recognisable on the market. Over 10 years of experience in building self-emissive panels has allowed for the refinement of each subsequent design, with the models from the 2024 range being the quintessence of this process. Of course, the use of this type of screen enables the achievement of flawless contrast and blacks, allowing viewers to immerse themselves in the world created by the director. This is possible thanks to the OLED panel, characterised by the absence of conventional backlighting, which instead allows current to pass through organic pixels. This permits super-accurate image control, thereby eliminating issues such as dimming of delicate fine details or the halo/blooming effect. Looking at both of our test scenes, we can notice two things: perfect light separation and a plethora of details in the movie "Sicario 2".

The television TCL MQLED85/C765 performs well in handling HDR. In the tested movie scenes, where the screen is at 100% brightness, the model achieves impressive results around 1000 nits, providing intense and realistic rendering of HDR content. However, similar to contrast, the dimming algorithm may show some limitations. Despite a large number of Mini LED zones, the television does not always manage to "wow" the user with brightness in very challenging test scenes. For instance, in the scene from the film "Life of Pi," where a bright moon appears against a dark background, and in another scene from "Sicario 2," where a very bright light effect is visible against a dark background, the television did not reach maximum intensity. For users expecting a perfect HDR effect in such extreme cases, the TCL MQLED may come up a bit short. However, in terms of colours, the television stands out with a very high coverage of the DCI P3 colour gamut at 95%, which is an impressive result comparable to much more expensive models. TCL MQLED85 / C765 offers support for various HDR formats, including Dolby Vision and HDR10+, which is crucial for cinema image fans. Although this model achieves brightness over 1000 nits, the TCL MQLED85 may struggle to reflect details in very high-contrast scenes. For better HDR quality control, the C765 is equipped with dynamic tone mapping, making the image more realistic and natural depending on the content.

The results of HDR materials are definitely among the better ones. Practically every film significantly exceeds the 700 nits barrier, which allows for a very realistic image. Of course, none of them surpasses the magical thousand, however, the combination of such results along with unlimited contrast and black effectively boosts the visual outcome. The last of the scenes, featuring a fullscreen sun burst, is indeed less bright than the others, although it still represents a respectable level. It's also worth mentioning the excellent coverage of the DCI-P3 colour palette, which will enable the achievement of exceptionally vivid colours.

The television TCL MQLED85/C765 was tested in movie mode, which, while seeming to be the best setting from the manufacturer, is not without its flaws. The colour reproduction in HD/SDR mode MQLED85 shows certain shortcomings. In the analysis of white balance, there is a significant lack of blue colour, which can affect the overall image quality, particularly in bright scenes where blue shades are crucial for natural representation. The overall image may then appear too warm. As for gamma contrast, the graph shows that there is a large jump above the reference line of level 2.4 at the beginning, which may suggest significant dimming of brightness in darker areas, leading to loss of detail in blacks. Then for most of the time, the values are below this line, which can lead to loss of detail in the brighter parts of the image. Such a distribution may negatively impact the perceived image quality, especially when watching regular TV in HD quality.

In the case of the 4K HDR image quality of the TCL MQLED85/C765 television, there is a noticeable excess of red colour in the analysis of white balance. This excess can significantly impact the viewer's experience, leading to several notable effects. First and foremost, an excessive amount of red can make other colours, such as green or blue, appear muted or unnatural. This distortion of colour balance can result in an overall impression of "oversaturation," which detracts from the image's naturalness and authenticity. In terms of contrast, the EOTF (Electro-Optical Transfer Function) graph indicates that most values are above the reference line, suggesting an intense boost in brightness in the bright areas of the image. However, the exception is the start of the graph, where the EOTF line is below the reference, which may lead to excessive dimming of small light elements.

Users should be aware that despite using the best mode, which is movie mode, the television is not free from flaws in the context of image settings, so it is worth considering adjusting the settings to achieve better results.

The best factory mode implemented in the tested television was "Filmmaker". That was the one we used during all tests. This mode, in terms of colour reproduction, turned out to be quite decent, although other flaws effectively detracted from the enjoyment of the viewing experience. Starting with the most basic one, which is white balance, it was easy to notice that this was marked by a dominance of red, which completely altered the characteristics of the picture. We could see a strong yellowing of the whites and a shift of all colours to warmer tones. The gamma, which is a graph as equally important, if not more so, was quite severely reduced, resulting in a significant drop in contrast, except for the start of the graph, where the television insidiously lost details. That’s all regarding SDR materials. Looking closely at films with a wide dynamic range, we can observe exactly the same phenomenon of white balance yellowing as in films with a standard colour palette. The EOTF curve, which replaces the gamma chart for us, is practically perfect and cannot be faulted.

After professional calibration of the television TCL MQLED85/C765, its colour properties in film mode have significantly improved, resulting in much more satisfying visual experiences. Both in SDR and HDR modes, the white balance shows no serious errors, and the graph appears to be much better harmonised. Users can now enjoy natural colour reproduction, which is crucial for achieving an authentic experience while watching films. It is worth noting that in HDR content, there may be minor colour reproduction errors at the end of the graph, but these are significantly smaller than before calibration. As a result, characters and landscapes become more realistic, enhancing the depth of immersion in the story.

Regarding contrast, the gamma curve, responsible for HD quality, has been completely free of drops below the reference line, which means better visibility of details in dark scenes. However, there is still a slight boost at the beginning of the graph, which may affect the perception of bright elements. For HDR content, the EOTF curve also shows fewer errors, although some issues with reproducing mid-tones may still be noticeable. The EOTF curve measured on real film scenes still shows a significant brightness boost, so the image may appear more intense but artificially brightened. This is a typical problem for TCL brand televisions, which may appeal to untrained viewers but can frustrate those more familiar with an ideal image.

What benefits does professional calibration bring to film enthusiasts? Thanks to it, viewing becomes even more realistic and immersive, allowing every scene to be experienced fully, preserving details and natural colours.

As we mentioned earlier, LG televisions are equipped with advanced tools for carrying out the calibration process. We used them to model the picture in line with what the director envisioned. And without modesty, we must admit that we achieved this phenomenally. Both SDR and HDR materials present a level that clearly indicates this is how a film should look. It's worth taking a look at the colour errors on the "ColorChecker" palette, where practically none of them exceed "1", except for two samples.

The fluidity of tonal transitions in the TCL MQLED85/C765 television is decent, although noticeable issues arise in both bright and dark test scenes. Particularly evident are the colour joins in the scene from the film "The Green Knight", where the red colour of the water transitions to black. Despite these imperfections, the overall gradient quality is acceptable and does not overly detract from the visual experience. The television handles most scenes well, offering satisfactory tonal transitions, contributing to an overall satisfying visual experience that won't spoil our cinematic enjoyment.

The fluidity of tonal transitions in LG televisions has always been a rather sensitive issue, as the manufacturer, despite impeccable performance in other areas, has almost always struggled to get this right. The evaluation results for the fluidity of tonal transitions in the tested television were quite good, with issues mainly visible in darker scenes, such as the last two scenes. Interestingly, this is a significantly better result than the highest model from the manufacturer, namely the LG G4.

We will now take another look at the tonal transitions on the TCL MQLED85/C765 TV, but in the context of lower image quality. Despite the presence of the "Gradual Smoothing" option, when set to "low", the effects are practically invisible, disappointing users who expect an improvement in image quality. On the other hand, the "high" setting yields minimal results, and worse still, it can blur important details, negatively impacting the sharpness and clarity of the displayed image. However, in the context of image scaling, the TV successfully displayed the image without overscan, meaning we do not lose any part of the view. The image looks quite decent, and details such as tree branches or the outlines of models do not show significant jaggedness, which positively affects the visual quality.

Once again, we will take a look at the feature responsible for gentle gradation, but we will also address the one that aims to enhance the quality of lower-quality materials. The default smoothing of tonal transitions, as we could see, was not the worst, but it can be improved further. The function has a slider that allows us to adjust its intensity. We recommend using the former, as it produces very good results and does not blur important details.

Image scaling on LG C4 is quite good, however, it cannot be said to be without flaws. The image is slightly sharper by default, although not in a very noticeable way. While jagged edges of trees can be seen, it is not a major issue when compared to other manufacturers.

TCL MQLED85/C765 is equipped with a standard refresh rate panel of 120 Hz, with the possibility of increasing it to 144 Hz when connected to a powerful computer. The television also offers a multi-level motion smoother, which is mainly aimed at users wanting to improve the fluidity of motion in films. It allows for adjusting the intensity of the effect on a scale from 0 to 10, enabling precise tailoring of the image smoothness to individual preferences. The response time of the panel is decent, but not perfect. We can observe motion blur occurring behind both dark and medium objects.

The maximum refresh rate we can set on the LG G4 is 144 Hz. Naturally, this is only possible when connecting the TV to a very powerful PC. Otherwise, we will operate at a maximum refresh rate of 120 Hz, which is recommended if we primarily want to watch sports or content with a lot of motion dynamics. For those who require high fluidity of the image, the manufacturer has implemented a multi-level motion smoother called "TrueMotion". It has been divided into two separate sliders that adjust the sharpness of moving images (De-Blur) and judder (De-Judder). Both sliders can be set in the range of 0 to 10, with each degree affecting the level of smoothing, allowing everyone to find their sweet spot.

The panel of the LG OLED C4 features an average response time of less than 1 ms (which directly results from our measurements), enabling the achievement of an extremely clear image, unattainable for LCD TVs, which can have response times of up to several milliseconds. This is clearly evident in the images from the "UFO Test," which show no trailing blur behind the object.

TCL MQLED85/C765 has achieved an impressive rating in the gaming features category, making it an excellent choice for gaming enthusiasts. The television supports all the latest technologies that significantly enhance the gaming experience. Among the key gaming features is ALLM (Auto Low Latency Mode), allowing the TV to automatically switch to low latency mode, minimising response time and ensuring smooth gameplay. VRR (Variable Refresh Rate) supported from 48 to 144 Hz eliminates stuttering and screen tearing in dynamic game scenes. Additionally, the TV supports the Dolby Vision Game Mode, which provides better image quality in games with exceptional depth of colour and contrast. TCL MQLED85/C765 also features a decent but not the best implementation of HGiG (HDR Gaming Interest Group), optimising the display of HDR games, however, in the case of TCL, it causes bright details to wash out, resulting in some elements merging into a white blob - more on this can be read in the colour reproduction section. It supports various resolutions such as 1080p@120Hz, 1440p@120Hz, and 4K@120Hz, allowing gamers to enjoy higher image quality and better fluidity. The Game Bar feature allows for easy switching between game settings and quick control of parameters, which significantly simplifies adjusting the TV to individual needs. With support for G-Sync and FreeSync technologies, users of NVIDIA and AMD graphics cards will be pleased with the refresh rate synchronisation capabilities, eliminating tearing and stuttering issues, ensuring smoother and more immersive gameplay.

MQLED85/C765 is a television that combines advanced technologies and excellent support for gamers, making it the ideal choice for those looking to maximise their gaming experiences.

We can now say that LG C4, like practically every OLED television from the manufacturer, is exceptionally good in terms of cooperation with consoles and PCs. Thanks to the implementation of four full-bandwidth HDMI 2.1 ports at 48 Gbps, the manufacturer has embedded all the features that enhance gaming comfort, including simultaneous support for FreeSync and G-Sync technologies. With such a tandem, players with graphics cards from AMD or nVidia can safely choose C4. However, what should please gamers demanding the highest possible quality the most is the simultaneous implementation of HDR Dolby Vision and HGIG mode. The former is particularly important as it operates with extremely low input lag in all settings.

A standard feature in televisions from the Korean manufacturer is also the implementation of GameBar, allowing for quick adjustments of settings "on the fly," without the need to exit the game. It also allows for image adjustments for people with visual impairments, which is an incredibly nice touch. Another important piece of information is that when VRR technology is enabled, we won’t experience a drop in contrast. This is, of course, due to the design of the panel and the absence of conventional backlighting. It is, however, normal for shades of grey to flicker slightly, although this is a characteristic feature of this function regardless of the manufacturer and television.

In summary: LG C4, just like all the manufacturer's OLEDs equipped with high-refresh-rate panels and HDMI 2.1 connections, creates a harmonious whole with consoles. In practice, it is a complete television, and if we expect the highest possible efficiency in gaming, C4 will be an ideal choice.

Latency in the TCL MQLED85 television reaches impressively low levels under any conditions. Even the most demanding gamers will surely appreciate the minimal input lag of just 8 ms at 4K 120 Hz settings with HDR. Moreover, the latency remains at the same level even when Dolby Vision HDR is enabled, which is not the case with many competing models.

The latency time of LG C4 is remarkably low in every scenario. Even the most avid gamers will surely appreciate the very low input lag at demanding 4K 120 Hz settings with HDR, which is only 5 ms. It's also worth noting that the lag at these same settings, but with Dolby Vision HDR enabled, remains unchanged, which is not so obvious with the competition. Therefore, it deserves the highest rating and recommendation.

TCL MQLED85 works well as a computer monitor. Thanks to its support for chroma 4:4:4, the text on the screen is sharp and readable, which is essential for people working with text documents or spreadsheets. One of the biggest advantages of this model is its exceptionally low input lag in "PC" mode, which is just 8 ms. This is a reference-level result that ensures smoothness and responsiveness, crucial for both gamers and those involved in video editing. However, it's worth noting that there is a slight issue related to font display on dark backgrounds. Upon zooming in on the tested font picture, it can be seen that horizontal lines are darker compared to vertical ones. This means that the sub-pixels in the TV may not fully illuminate in such cases, which can affect the quality of displayed text. Nonetheless, the overall performance of TCL MQLED85 as a computer monitor is very good and will certainly meet the expectations of many users.

LG C4 combined with a PC works wonderfully, thanks to its very low latency of just 13.5 ms, which is practically instantaneous feedback between the mouse, eye, and screen. An extremely important aspect when working on a screen is the readability of text, which in the case of the tested TV is very good. However, it is worth noting that to achieve sharp fonts, you need to enable the passthrough option in the settings.

The RWBG pixel layout does not significantly affect the display of fonts or letters, which is a significant advantage over Samsung's QD-OLED panels. Users of both Windows-based PCs and macOS will surely be pleased with their experience on the tested TV screen.

The viewing angles on the TCL MQLED85 television are not its strong suit. The use of a VA panel causes the image to lose a significant amount of brightness when viewed at an angle. Changing the viewer's position, especially in a larger group setting, can make colours appear less saturated, and contrast may be less distinct. For this reason, it's recommended to sit directly in front of the screen to fully enjoy the picture quality. Although the television offers excellent colour reproduction from a direct view, the loss of brightness and detail at an angle can be problematic for those who plan to use the television in a larger room or from various locations.

The undisputed advantage of OLED panels is their efficiency in the context of group viewing, meaning from various angles. LG C4 maintains very good contrast, colour saturation, and fidelity. Although this isn't a result of organic TVs supported by MLA technology, it's fair to say that anyone who purchased the device was satisfied with the results obtained. However, it should be noted that at sharp angles a slight greenish tint can be observed. This is a characteristic feature of WRGB panels from LG, without the aforementioned micro-lens technology, and unfortunately, there's nothing that can be done about it.

MQLED85 performs reasonably well in daylight conditions, and it's worth noting the satin finish of the panel. While it doesn't excel at reducing reflections, it offers decent performance in various lighting conditions. An average brightness level above 600 nits is an impressive result, allowing for comfortable viewing even in well-lit rooms. As a result, the television performs well both during the day and during evening movie screenings, providing satisfactory picture quality.

The maximum brightness of the television in SDR materials is 367 nits. For an OLED television, this is a very good result and allows for quite comfortable viewing during the day. It's worth noting two things. Thanks to the glossy coating of the panel, the light reflections are well held in place and do not spill over the rest of the panel. The second issue is the brightness of the screen when fully filled with white, oscillating around 220 nits, which is a remarkable result, as until recently, OLED televisions in this category could only boast brightness half as much. As a result, the conditions for watching, for example, winter sports will be very good.

TCL MQLED85 TV offers many features that enhance user comfort, with the central point of its functionality being the Google TV system. This modern interface allows for easy content browsing, as well as access to apps available in the Google Play store. Users can take advantage of voice search in Polish, which greatly simplifies navigation and allows for quick finding of interesting shows, movies, or apps. It's also worth noting that Google TV is currently the only system on the market that does not restrict Polish users' access to apps, offering the greatest availability among all available platforms. However, in the context of traditional TV watching, this television has its limitations. It does not offer a recording function, which may be a significant downside for those who would like to save their favorite programs. Additionally, the lack of Picture-in-Picture (PIP) option limits the ability to simultaneously track multiple video sources. On the other hand, the TV features a "MultiVision" function, which allows for screen splitting between the TV and a mobile device. This way, users can use apps on their phone while still watching a TV program. This solution will certainly appeal to those who enjoy multitasking and want to watch TV while also engaging with social media or browsing the internet on their smartphone. Despite some limitations, the TCL MQLED85 TV presents itself as a solid option for users who value modernity and functionality.

LG uses the well-known proprietary WebOS system that has been around for many years. The system offers virtually all the major apps, and the few that are missing can be counted on one hand, such as CDA or KODI. It's also worth noting that the modern web browser and the remote with a built-in mouse allow for convenient access to streaming services in this way, if there isn't a built-in app.

WebOS also features a highly praised ability to perform operations using a cursor that appears when the remote is moved. The convenience of this function is invaluable when entering queries or passwords for portals. WebOS, like most systems, also supports features such as screen mirroring, AirPlay, voice searching in Polish, and the ability to connect headphones via Bluetooth. On a more practical note, WebOS allows simultaneous use of headphones and the television speaker, which will certainly be a significant help for those with hearing impairments. One of the more interesting features, particularly appreciated by sports fans, is the ability to turn on an alert for an upcoming match, ensuring that we never miss a broadcast. The home panel also deserves praise, allowing for control of all smart devices connected to the home network. For example, the end of a wash cycle will be signalled by a notification in the top right corner.

In summary, the WebOS system, although less known and with certain limitations compared to Android TV, offers stable and quick performance and supports most functions that users may need. It is a solid solution for those looking for a simple and effective operating system in their television.

Thanks to the built-in player, the television is able to play most file formats found on external storage, making it a versatile tool for consuming multimedia. However, there may be some limitations in supporting certain formats, which can be bothersome 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. This gives users the ability to choose applications that best meet their needs, significantly increasing the functionality of the television.

The default file player on LG C4 handles all photo resolutions exceptionally well. It successfully plays videos recorded in practically all the most popular formats, including Dolby Vision. The only codec that the C4 won't play is H.266 VVC, although this is currently rather uncommon. It's a pity that subtitles in .txt format are not supported. Attention should be paid to the supported photo formats, of which there are only three: JPEG, PNG, and, importantly for Apple phone users - HEIC. However, the tested television cannot be faulted for a lack of variety in audio files, which can be played without a compatibility warning.

The sound of the television TCL MQLED85 can be described as decent, making it sufficient for everyday watching of movies, TV shows, and gaming. The speakers branded with Onkyo offer surprisingly good audio quality, and the sound does not crackle or distort even at higher volume levels.

The audio system implemented in LG C4 is very well tuned, allowing us to experience strong bass as well as balanced mid and high tones. We can confidently say that in its price range, it's one of the better sounding televisions. However, we believe that those deciding to purchase the C4 will already have a dedicated audio set. The presence of DTS-HD Master Audio and Dolby Atmos codecs will also be significant.
