Compare: TCL MQLED85 / C765 vs LG 55 B4

TCL MQLED85, or model C765, is a television that can truly surprise, especially in this price range. It is one of the cheapest models with mini-LED technology, which is immediately evident from 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 films in the evening is a pure pleasure – the blacks are genuinely deep, and the image in dark scenes appears clear. However, it is not perfect – in some shots, you can notice minor issues with small bright elements, but this is really a trifle compared to what this model offers. Google TV works excellently here – there are plenty of applications, and using the system is simply convenient. Voice control in Polish operates flawlessly, which can be particularly useful if you don’t want to type film titles using the remote. Of course, there are minor shortcomings, like the lack of recording features, but these are not things that hinder everyday use. For gamers, it is also a great option. Support for HDMI 2.1, VRR, and low input lag make the television handle consoles well and compete effortlessly with more expensive models from Korean or Japanese manufacturers. It's hard to find something better in this price range concerning smooth and responsive gameplay. During testing, we encountered a few minor software issues, but it's difficult to say if this is a significant drawback. We hope that TCL will release updates, so there is a chance this issue will be resolved quickly. TCL MQLED85/C765 is an excellent choice if you’re looking for a television with good picture quality and modern features at a reasonable price. This model combines accessible mini-LED technology with a convenient Google TV system, while also performing exceptionally well in gaming. The minor software shortcomings are something you can live with, especially considering what this television offers in its class.

LG OLED B4 is an exceptionally versatile device in the semi-premium category. For how else could one describe an OLED television that is so well-priced, and whose price, as history shows, will quickly fall? Ideal blacks and contrast are two things that inevitably mesmerise, and we are certain that anyone who has owned a device with this panel will not be able to return to LCD units. The brightness results of the television in HDR content may seem rather low; however, in this case, thanks to this particular panel, they will appear optically much higher. It is worth noting their stability and uniformity in practically every scene. In this case, a minor downside is the brightness of a full-frame shot filled with a large amount of white. However, we do not believe this to be a serious problem, as there are not many such instances anyway. The factory colour reproduction also deserves praise, which in our specimen is very decent, but one cannot help but remember how beneficial calibration has been for the image, allowing the director's intentions to be conveyed fully. LG B4 will be an excellent choice for all kinds of gamers, as well as sports enthusiasts. The former will certainly appreciate the rich support in the form of all the conveniences stemming from the HDMI 2.1 standard. Meanwhile, the latter will benefit from the advanced motion smoothing with multi-step adjustments. And lastly, one cannot overlook the convenience provided by the remote control with a built-in gyroscope, allowing it to function like a mouse. The WebOS system, which we will navigate, is extremely smooth and responsive. It offers a multitude of applications, which will be more than sufficient for the vast majority of users. The heart of the LG B4 television is the advanced Alpha processor, responsible for the smoothness of the image and advanced signal analysis. In summary: who is the LG OLED B4 for? It is the perfect device for those expecting the highest possible image quality within a given budget, but not only that. The LG B4 stands out significantly above its competition at this price point, which cannot offer such high-quality images.

TCL MQLED85/C765 stands out due to its use of a VA panel and Mini LED backlighting, which makes a significant difference compared to traditional backlighting systems. Mini LED, with its considerably smaller diodes, allows for more precise control of the screen's backlighting, resulting in much better contrast and deeper blacks. The 55-inch model we are testing has an impressive number of over 700 local dimming zones, providing exceptional precision in image display. However, it is worth noting 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 displays to achieve better results in terms of contrast and black levels. Thanks to the vast number of zones, the TCL MQLED85/C765 achieved a performance comparable to OLED screens on our first test scene from the film "Oblivion," offering nearly reference-level contrast. But what happens when we test this model in even more demanding conditions? How will the television perform in more challenging scenarios? Overall, the TCL MQLED85/C765 performs very well in displaying blacks, 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 recent test scene from the Pioneer Kuro test disc. Despite some imperfections in the local dimming algorithm and the slight occurrence of the HALO effect (which is a bright halo around bright objects on a dark background caused by screen local dimming deficiencies), the results achieved by the TCL MQLED85/C765 are impressive, especially considering its price. This television offers contrast and black depth that can compete with models that are even half again as expensive.

LG B4 uses OLED panels produced by LG Displays. The use of this type of panel provides us with perfect contrast and black levels. With such conditions, the picture is incredibly vivid and one might even get the impression that it is three-dimensional. The series of the manufacturer with the letter "B" has always been an ideal solution for those seeking very good picture quality while not wanting to pay extra for features that are only available in higher series. Therefore, these models have become something of a dark horse in this price range, as their advantageous pricing primarily competes with Mini LED televisions. It is not difficult to say that these models have won these battles due to the absence of characteristic flaws associated with LCD receivers with multi-zone backlighting, such as blooming/halo effects or dimming of images containing fine bright details. And as we can see in the test scenes from the films "Oblivion" and "Sicario 2," the fidelity is at the highest level. Looking at the first one, we see a spectacular play of lights that, despite their brightness, are perfectly separated from one another. Even a more challenging scene with a helicopter poses no problem for LG B4, showcasing a wealth of details and a unique colour grading specific to this title.

The television TCL MQLED85/C765 handles HDR well. In the tested movie scenes where the screen is covered with 100% brightness, the model achieves impressive results of around 1000 nits, providing intense and realistic rendering of HDR content. However, similar to contrast, the dimming algorithm may exhibit certain 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 example, 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 on a dark background, the television did not reach maximum intensity. For users expecting perfect HDR performance in such extreme cases, the TCL MQLED may be slightly disappointing. However, in terms of colours, the television stands out with very high coverage of the DCI P3 colour palette 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 significant for cinema image enthusiasts. Although this model achieves brightness over 1000 nits, TCL MQLED85 may struggle to reflect details in very high-contrast scenes. For better HDR quality control, C765 is equipped with a dynamic tone mapping option, making the image more realistic and natural depending on the content.

The brightness results in HDR materials for LG B4 are very good. It is true that none of them exceed 1000 nits, although the stability of luminance is excellent and looks practically the same in every scenario. The only moment where the tested television performs worse is the last of the scenes, although this should not be surprising. Large frames filled with a lot of white have always been, and probably will continue to be, somewhat of a weakness for OLED televisions. However, the combination of perfect contrast, black levels, and brightness of LG B4 allows for a full experience of the HDR effect. Additionally, the incredibly high coverage of the DCI-P3 colour gamut deserves recognition, reaching 99%. This makes the colours look incredibly vivid and striking.

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

In the case of 4K HDR image quality of the TCL MQLED85/C765, there is a noticeable excess of red in the analysis of white balance. This excess can significantly affect the viewer's experience, leading to several significant effects. Firstly, 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 "over-saturation," which detracts from the naturalness and authenticity of the image. As for contrast, the EOTF (Electro-Optical Transfer Function) graph indicates that most values are above the reference line, suggesting an intense boost in brightness in bright areas of the image. However, there is an exception at the beginning of the graph, where the EOTF line is below the reference line, which can 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 terms of image settings, so it is worth considering adjusting the settings to achieve better results.

The best factory mode prepared by the manufacturer is "Filmmaker," which is exactly what we used throughout the entire testing procedure. We must admit that the unit we received out of the box had quite good colour reproduction. The biggest problem in both SDR and HDR content turned out to be white balance. In the former, a strong red hue was evident, causing the displayed image to have a pronounced yellow tint, particularly noticeable on skin tones and whites. In higher quality materials, this colour was also accentuated, but due to a lack of blue, there were also signs of green visible. Apart from these issues, we also encountered problems with grayscale and the colours themselves.

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

In terms of contrast, the gamma curve, responsible for HD quality, has been completely free of drops below the reference line, meaning better detail visibility in dark scenes. Nevertheless, 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 exhibits smaller errors, although certain issues with medium tone reproduction may still be noticeable. The EOTF curve measured on actual movie scenes still shows a significant brightness boost, making the image appear more intense but artificially brightened. This is a typical problem for TCL televisions, which may appeal to inexperienced viewers, but can be irritating for those more familiar with an ideal image.

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

LG B4 has been providing very advanced calibration tools in its televisions for years. We can even say that as the only manufacturer on the market, it allows for such deep intervention in image adjustment. It is thanks to these tools that we were able to calibrate the device so well. Evidence of this is the extremely low deltaE errors, which can be said to be at a reference level. Both SDR and HDR materials now look exactly as intended by the film director. It is no coincidence that televisions of this brand are most often used as preview screens for various graphic or post-production studios.

The fluidity of tonal transitions in the television TCL MQLED85/C765 is quite decent, although some issues are noticeable in both bright and dark test scenes. In particular, colour blending is evident in the scene from the film "The Green Knight", where the red colour of the water transitions to black. Despite these imperfections, the overall quality of gradation is acceptable and does not overly detract from the visual experience. The television handles most scenes well, offering satisfactory tonal transitions, which contributes to an overall pleasing visual experience that will not spoil our cinema enjoyment.

The fluidity of tonal transitions, often overlooked in various tests on competing portals, is an equally important aspect of image quality assessment. It is particularly important when watching material that features a wealth of colours and many intricate effects, where textures blend. This often leads to the so-called banding of colours, which is a lack of smooth gradation. The tested television handles tonal transition smoothing quite well. However, it is worth noting that it has its weaker moments, such as a bright coloured sky in the film "Kingsman" or "The Martian". Nevertheless, these are not aspects that detract from the viewing pleasure. Therefore, we positively assess the quality of tonal transitions in LG B4.

Let’s take another look at the tonal transitions in the TCL MQLED85/C765 television, but in the context of poorer image quality. Despite the presence of the "Gradual Smoothing" option, when set to "low," the effects are practically invisible, disappointing users expecting an improvement in image quality. On the other hand, the "high" setting produces minimal results, and worse still, it can blur significant details, negatively affecting the sharpness and clarity of the displayed image. However, in the context of image scaling, the television successfully displayed the image without overscan, meaning we do not lose any part of the view. The image looks rather decent, and details such as tree branches or the outlines of models do not exhibit significant jaggedness, which positively impacts the visual quality.

In this paragraph, we will take another look at the function for smoothing tonal transitions, but we will also check how the television handles lower quality material. As we have managed to verify, the setting responsible for smooth gradation works quite efficiently, although it has its weaker moments. Just as the function works correctly in SDR content, it becomes rather useless in HDR content. Even at the lowest of the options, it blurs essential details, which is why we advise against using it.

The image scaling on LG B4 is rated rather moderately positively. Although there is no edge doubling, the image itself is naturally "soft." We can change this by adjusting the sharpness slider.

TCL MQLED85/C765 is equipped with a panel featuring a standard refresh rate of 120 Hz, with the capability to increase to 144 Hz when connected to a powerful computer. The television also offers a multi-level motion smoother, primarily aimed at users wishing to enhance motion fluidity in films. It allows for the adjustment of effect intensity on a scale from 0 to 10, enabling precise tuning of image smoothness to individual preferences. The response time of the panel is decent, but not perfect. We can observe blurring occurring behind both dark and medium objects.

The maximum refresh rate that we can set on the LG B4 is 120 Hz. This is the absolute minimum for those requiring high image fluidity. The manufacturer has implemented a multi-step motion smoother called "TruMotion". It has been divided into two separate sliders adjusting the sharpness of moving images (De-Blur) and jitter (De-Judder). Both sliders can be set in the range from 0 to 10, with each degree affecting the level of fluidity, so everyone can find their golden mean.

The LG OLED B4 panel features an average response time of 0.1 ms (which directly results from our measurements), allowing for an incredibly clear image, unattainable for LCD televisions, whose response times can be as high as several milliseconds. This is clearly evident in the pictures from the "UFO Test", showing no trail following the object.

TCL MQLED85/C765 has received 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), which automatically switches the TV to low-latency mode, minimising response time and ensuring smooth gameplay. VRR (Variable Refresh Rate) functioning in the range of 48 to 144 Hz eliminates stuttering and screen tearing in dynamic game scenes. Additionally, the TV supports Dolby Vision Game Mode, which provides better image quality in games with exceptional colour depth and contrast. TCL MQLED85/C765 also features a decent if not the best implementation of HGiG (HDR Gaming Interest Group), optimising HDR game display; however, for TCL, it causes detail in whites to be brightened, resulting in some elements merging into a white blob - we can read more about this in the colour reproduction section. It supports various resolutions, such as 1080p@120Hz, 1440p@120Hz, and 4K@120Hz, allowing players to enjoy higher image quality and better fluidity. The Game Bar feature allows easy switching between game settings and quick parameter control, greatly simplifying the adjustment of the television 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, thereby providing a smoother and more immersive gaming experience.

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

The LG B4 television is equipped with four fully-fledged HDMI 2.1 ports with a full bandwidth of 48Gbps. All features that are identical to this standard were activated without any issues, and throughout the entire testing process, they did not cause any problems. The combination of such extensive functionality and low input lag suggests that the tested television is truly made for gaming. This is not surprising, considering that the manufacturer has always placed great emphasis on this. Therefore, we can enjoy both the properly implemented HGIG mode and gaming in Dolby Vision with low latency. This pairing will certainly attract the attention of all passionate gamers for whom quality is paramount.

An additional standard in televisions from this Korean manufacturer is the implementation of GameBar, allowing for quick adjustment of settings "on the fly," without the need to exit the game. It also enables image adjustments for individuals with visual impairments, which is a very nice touch. Another important piece of information is that when VRR technology is enabled, we will not experience a drop in contrast. This is thanks to the construction of the panel and the lack of conventional backlighting. However, it is normal for shades of grey to flicker slightly; nevertheless, this is a characteristic feature of this function regardless of the manufacturer or television.

In summary: the LG B4, like all of the manufacturer’s OLEDs equipped with 120Hz panels and HDMI 2.1 ports, creates a harmonious whole with the console. In practice, this is a comprehensive television, and if we expect the highest possible efficiency in gaming, B4 will be the ideal choice.

The latency time on the TCL MQLED85 television reaches impressively low levels in all 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 with Dolby Vision HDR turned on, which is not the case for many competing models.

Input lag for the LG B4 is at an incredibly low level in every scenario. Even the most dedicated gamers will certainly appreciate the very low input lag at demanding 4K 120 Hz settings with HDR, which is just 5 ms. It is also worth noting that the lag at these same settings, but with Dolby Vision HDR enabled, remains consistent, which is not as evident with the competition. Therefore, it deserves the highest rating and recommendation.

TCL MQLED85 will perform well as a computer monitor. With support for chroma 4:4:4, the text on the screen is sharp and legible, which is important for those working with word documents or spreadsheets. One of the greatest assets 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 fluidity and responsiveness, crucial for both gamers and those engaged in video editing. However, it is worth noting that there is a certain issue related to font display on dark backgrounds. When zooming in on the tested font image, one can see that the horizontal lines are darker compared to the vertical ones. This means that the sub-pixels in the television do not fully illuminate in this case, which can affect the quality of the displayed text. Nevertheless, the overall performance of TCL MQLED85 as a computer monitor is very good and will certainly meet the expectations of many users.

LG B4 combined with a PC performs excellently, thanks to a very low latency of just 13.5 ms, which is practically an instant response between the mouse, the eye, and the screen. An extremely important factor when working on a screen is primarily the readability of the text, which in the case of the tested television is very good. However, it is worth noting that to achieve sharp fonts, one must enable the passthrough option in the settings.

The RWBG pixel layout has no significant impact on the display of fonts or letters, which provides a considerable advantage over Samsung's QD-OLED matrices. Users of both Windows and macOS equipped computers are sure to be pleased with the performance on the screen of the tested television.

The viewing angles on the TCL MQLED85 television are not its strong suit. The use of a VA panel means that the picture loses a significant amount of brightness when viewed at an angle. Changing the viewer's position, especially when watching with a larger group, can cause colours to appear less saturated and the contrast to become less pronounced. For this reason, it is 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 planning to use the television in a larger room or from different locations.

The undisputed advantage of OLED panels is their performance in the context of group viewing, that is, from various angles. LG B4 maintains very good contrast, colour saturation, and fidelity. Although this is not the result of organic televisions supported by MLA technology, one cannot say that anyone who purchased the device was dissatisfied 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 LG's WRGB panels, without the aforementioned micro-lens technology, and unfortunately, there is nothing that can be done about it.

MQLED85 performs reasonably well in daytime conditions, and it is worth noting the satin finish of the panel. Although it doesn't handle reflections perfectly, it offers decent performance in various lighting conditions. An average brightness level of over 600 nits is an impressive achievement, allowing for comfortable viewing even in well-lit rooms. As a result, the television performs well both during the day and during evening movie sessions, providing satisfactory picture quality.

The maximum brightness of the television in SDR materials is 370 nits. For an OLED television, this is a very good result and allows for quite comfortable viewing during the day. It is worth paying attention to two things. The first is the rather mediocre handling of reflections caused by the satin finish of the panel, which means that direct light hitting the television will be quite obtrusive. The second issue is the brightness of the screen when filled 100% with white, oscillating around 260 nits, which is an excellent result, as until recently, OLED televisions in this price range could "boast" a brightness twice as low. Thanks to this, the conditions for watching, for example, winter sports will be very good.

TCL MQLED85 television offers many features that enhance user comfort, with the centrepiece of its functionality being the Google TV system. This modern interface allows for easy content searching as well as access to applications available in the Google Play store. Users can utilize voice search in Polish, which greatly facilitates navigation and allows for the quick discovery of interesting programmes, films, or applications. It is also worth noting that Google TV is currently the only system on the market that does not restrict Polish users in accessing applications, offering the greatest availability among all platforms. However, in the context of traditional television viewing, this television has its limitations. It does not offer recording functionality, which may be a significant drawback for those who would like to save their favourite programmes. Additionally, the absence of the Picture-in-Picture (PIP) option limits the ability to simultaneously follow several video sources. On the other hand, the television features the "MultiVision" function, which allows for screen division between the television and a mobile device. This enables users to use applications on their phone while simultaneously watching a television programme. This solution will certainly appeal to those who enjoy multitasking and want to watch television while using social media or browsing the internet on their smartphone. Despite certain limitations, the TCL MQLED85 presents itself as a solid option for users who value modernity and functionality.

LG B4 uses the well-known proprietary system WebOS. The system offers practically all the most important applications, and those that are lacking can be counted on one hand, such as CDA or KODI.

WebOS also boasts a highly appreciated ability to perform operations using a cursor that appears when the remote control is moved. The convenience of such a feature is invaluable when entering queries or passwords for portals. WebOS, like most systems, also supports functions such as screen mirroring, AirPlay, voice search in Polish, and the capability to connect headphones via Bluetooth. On a more practical note, WebOS allows us to use both headphones and the television speaker simultaneously, which will certainly be a great help for those with hearing impairments. Among the more interesting features, particularly appreciated by sports fans, is the option to enable an alert for upcoming matches, ensuring that we never miss a broadcast. The home panel also deserves praise for allowing control of all smart devices connected to the home network. For example, the end of a washing cycle will be signalled by a notification in the top right corner.

In summary, the WebOS system, despite being less known and having certain limitations compared to Android TV, offers stable and fast operation and supports most functions that users may need. It is a solid solution for those looking for a simple and effective operating system in a television.

Thanks to the built-in player, the television is capable of playing most file formats found on external storage devices, making it a versatile tool for consuming multimedia. However, there may be certain limitations in supporting some formats, which could be annoying for more demanding users. Fortunately, the Google TV system allows 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 enhancing the functionality of the television.

The default file player in LG B4 definitely handles most images well, although the absence of a few equally popular formats is surprising. We can successfully play videos recorded in virtually all the most popular formats, including Dolby Vision. The only codec that LG B4 will not play is H.266 VVC, although this is currently rather unused. However, it is worth noting the supported image formats, of which there are only two: JPEG and PNG. Users of Apple devices may feel disappointed by the lack of support for the HEIC format, which is the default format when taking photos. The remedy for this is to use the built-in AirPlay feature. We will also mention the lack of support for TXT subtitles.

The sound of the television TCL MQLED85 can be described as decent, making it sufficient for daily viewing of films, television programmes, and games. The speakers branded by Onkyo offer surprisingly good audio quality, and the sound does not screech or distort even at higher volumes.

The audio system built into the LG OLED B4 can be considered quite good. We can say that it performs well for its price range. The bass is quite noticeable, but does not overpower the other frequencies. It can be said that the sound is fairly well balanced. We believe that those opting for this class of display are, or will be, in possession of an appropriate audio system. Therefore, the presence of DTS-HD Master Audio and Dolby Atmos codecs is not insignificant.
