Our verdict

LG G4 is a strong contender for being the best television of 2024. Thanks to the combination of OLED black and MLA technology, we will get an incredibly dynamic and vibrant image that will surely captivate us completely. LG G4 is also proof that televisions equipped with an OLED panel supported by MLA technology are indeed suitable for viewing in bright rooms. The operating system, while not as open as the competition, allows for many possibilities. Its greatest advantage is the well-known remote with a cursor, which makes controlling the unit (in our opinion) one of the most convenient on the market. Factory colour reproduction, although not at a high level, after undergoing calibration, can be considered almost reference-quality, providing a truly cinematic image. No wonder post-production studios choose televisions from this manufacturer. They uniquely offer such a deep capability to adjust the image, thanks to 3D LUT calibration. It seems that the biggest (and perhaps only) drawback of this television is the tonal transitions, which, while far from perfect, cannot be said to detract from the viewing experience. The remedy is provided by the manufacturer themselves, and enabling the "Smooth Gradation" function will remove the vast majority of any choppiness. LG G4 also performs exceptionally well when watching all kinds of sports or other dynamic scenes. The motion smoother is incredibly advanced and allows for adjustment of smoothness to suit individual needs. Thanks to HDMI 2.1 ports with full functionality and the manufacturer's attention, the tested television will find its place in the homes of many passionate gamers. Each of the essential features works flawlessly, and the low input lag in every mode is very pleasing. In summary, LG G4 is an incredibly versatile television, allowing for entertainment in excellent quality both at night and during the day.

The mid-range television segment is expanding rapidly, and TCL C75B demonstrates that it’s possible to get really solid equipment in this price category. This model is clearly designed with gamers in mind – the HDMI 2.1 port offers a lot of potential, providing VRR, ALLM, and impressive 144 Hz refresh rate in 4K (or 240 Hz in Full HD), which will certainly please both gaming and sports fans. The TV’s operation is pleasant and intuitive, mainly thanks to the Google TV system. While there may be minor stutters, the wealth of available apps and features more than compensates for this – practically everything we need is at our fingertips or even at the sound of our voice if we wish to talk to the remote in Polish. As for picture quality, TCL C75B also performs well. Thanks to the VA panel, it boasts quite good contrast, and the presence of Dolby Vision allows for enjoyable HDR effects, even if the brightness isn’t mind-blowing. Of course, it isn't without its flaws – despite the fast panel, there is some motion blur, and the lack of traditional features (like USB recording) may disappoint some users. Nevertheless, in its price category, the C75B is a very attractive option, especially for those looking for a screen designed for high-level gaming.

Halo effect and black detail visibility:

LG G4, with its OLED panels produced for over 10 years, delivers perfect contrast, black levels, and detail reproduction in the darkest scenes. It's worth noting that the panel itself is equipped with MLA (Micro Lens Array) technology, which LG showcased just a year ago with the launch of its predecessor. The use of an organic panel not only allows for achieving pitch-black blacks but also provides extraordinary immersion and a three-dimensional effect in the image, which is hard to find even in the best Mini LED TVs. Such image quality is closely linked to OLED panel technology, as each pixel is controlled by an electrical impulse rather than shading filters on the panel. Therefore, if we want to achieve black, the pixel is simply turned off. This is very evident in test images, where the spotlight provides high brightness while being perfectly separated from each other. The situation remains unchanged in the challenging scene from "Sicario 2," where no imperfections from zone dimming can be seen, which we might encounter in LCD TVs.

The TV we tested, TCL C75B in size X," is equipped with a VA panel, which naturally provides quite decent contrast results – and that’s what we observed during our tests. On each test pattern, the TV achieved a contrast level of around 5500:1. This is a result that can be considered very good in this price category. The black in this model performs really well, though of course, it’s far from perfect.

Due to the C75B belonging to the mid-range segment, we won’t find local dimming technology here. This is particularly noticeable in more demanding scenes, such as those from the film Sicario 2, where we noticed that the black takes on a navy hue instead of a pitch-black. This limitation of panels without local dimming can be particularly evident in evening viewings with the lights off, when dark elements of the image are more pronounced. It's worth keeping this in mind when choosing a TV in this category, especially if we care about the best quality of black while watching movies at night.

LG G4 guarantees an incredibly vibrant HDR effect, placing the television firmly at the top of the rankings. The highest model in the manufacturer's 2024 portfolio, equipped with the second generation of microlens technology (MLA), has achieved a maximum brightness level of 1474 nits in real scenes. The only area where the product of the Korean manufacturer may fall short compared to LCD televisions with Mini LED backlighting is during a full-screen scene featuring a lot of white. If we were to disregard the latter scene, the average result would be even higher. It's also worth mentioning scenes with very fine details, where each one shone at full intensity, which is not as evident in non-OLED televisions. The combination of such brightness and wide coverage of the DCI-P3 color space ensures that HDR materials are more engaging than ever before.

During our brightness test, the TCL C75B "spat out" around 380 nits of brightness. We recorded similar results while watching most of the films we tested. These can be considered average – the TV performs decently in this segment, but around 400 nits is definitely too low to fully experience the magic of HDR effects. Of course, such results are better than those of budget models, which can achieve nearly half the brightness values. However, for HDR enthusiasts seeking stronger lighting effects and greater realism, the C75B may prove insufficient. On the plus side, it's worth mentioning the coverage of the DCI-P3 colour gamut at 95%. This is a very good result that easily suffices to enjoy a wide range of colours in content available on popular streaming platforms. Vivid and rich colours are definitely a strong point of this model.

Factory color reproduction

After calibration

The best factory mode in terms of colour reproduction was "Filmmaker". This is the one we used during our tests. Let's check how its characteristics looked before the calibration process. Taking a closer look at the white balance first, we can notice a significant dominance of red and green colour. As a result, the image had a warm yellow tint. This is the kind of characteristic we usually observe in "Cinema", "Filmmaker", or similarly named modes. The effect of such a colour balance was clearly visible in both SDR and HDR content, which, after switching from "Standard" mode, was distinctly yellowed. Now let's move on to two graphs that are responsible for brightness characteristics, and consequently, image contrast. The first one (Gamma), representing materials with a standard colour palette, performed decently. For most of the time, the midtones and bright whites were represented very accurately, however, it noticeably lost the darkest details which blended into a black patch. On the other hand, HDR materials, represented by the EOTF curve graph, exhibited a significant drop in contrast due to a strong boost in brightness. There was also an issue with the colours themselves as seen on the "ColorChecker" graph since they were noticeably undersaturated.

TCL C75B offers various picture modes, but in our opinion, the best choice is the “Film” mode. Although its settings are quite decent, the TV struggles with certain colour reproduction issues. In tests, we noticed that the image had a noticeably pinkish hue compared to what could be considered correct. This effect was particularly evident in skin tones, which appeared unnaturally flushed. The main culprit of this phenomenon turned out to be the white balance, characterised by an excess of blue and red in both HD and 4K HDR materials.

An additional problem was the way brightness was reproduced. The gamma, which is responsible for the visibility of details in darker materials, was definitely boosted, causing details in the darkest parts of the screen to be invisible, disappearing into complete black (e.g., the bottom part of the screen in the comparison image - the area around the actress's ear). The situation was similar on the EOTF curve, which was below the correct value, suggesting that a similar issue may be encountered in 4K HDR content.

Thanks to our experience and the appropriate tools, we decided to take matters into our own hands and check how much could be extracted from this model after professional calibration. The details are described in the next section.

Color reproduction after calibration

9.5/10

8.2/10

The manufacturer has been implementing extensive support for the calibration process in their LG televisions for many years. Therefore, we used 2- and 20-point grey scale adjustments along with an advanced CMS (Color Management System) and got to work. As you can see, thanks to the procedure carried out, each of the parameters has significantly improved. The use of tools has resulted in extremely beneficial effects, which include: studio colour reproduction, recovery of details in dark areas of the image, appropriate brightness characteristics, and proper colour saturation. Thus, we have maximised our approach to the reference image, or the one that the film director saw on the preview monitor. It is worth noting that the LG G4 televisions are the only ones that allow for even deeper intervention in image quality due to the capability to calibrate with 3D LUT matrices. However, this solution is recommended only for post-production or graphic studios.

After calibration, TCL C75B has clearly improved when it comes to colour reproduction. Although the TV doesn't offer too many options for adjusting the white balance, we managed to improve its settings quite a bit. As a result, the image is no longer overly pink, and the colours now look much more natural and harmonious.

The gamma jump that was previously an issue hasn't completely disappeared, but we were able to significantly reduce it. This has made details in dark scenes more visible – both in HD and 4K HDR content.

Unfortunately, the lack of local dimming is still noticeable. The 'blooming black' effect remains, but that's a limitation of the display itself. Still, the colours post-calibration look significantly better, and the image is much more pleasant to watch.

Smoothness of tonal transitions

6.2/10

8.2/10

The tonal transitions presented on LG G4 are not among the top performers. Each scene played from a BluRay disc with 10-bit HDR exhibited noticeable choppiness in the colour transitions. This was particularly evident in the case of the film "The Green Knight," where issues related to posterisation were especially pronounced. This effect could also be observed in films with moderate to high brightness, such as "The Martian" or "Kingsman," which is rarely seen in televisions (especially of this class), which took us by surprise. Such results suggest that in scenes with low luminance and a lot of black, this issue will be troublesome, even for a layman.

When it comes to tonal transition fluidity, TCL C75B performs really well. It particularly excels in gradation of the darkest colours – here the television does not disappoint and presents a high-quality image.

Some imperfections can be noticed in the brightest areas of the screen, such as in a scene from the film Kingsman (sun in a blue sky). Nevertheless, the final effect should satisfy the vast majority of users.

The tested television did not perform well with content rich in tonal transitions, resulting in a strong posterisation effect. However, there is a partial remedy for this ailment. The manufacturer has equipped the LG G4 with a smoothing system called "Gentle Gradation," which we can apply at three levels: Low, Medium, and High. Each of these options guarantees quite high smoothing effectiveness on bright colours, though low on darker ones. We recommend primarily using the first one due to the fact that the other two interfere with directorial intentions, removing film grain.

When watching lower-quality content, the efficiency of the television during upscaling is extremely important. The image from the tested television is sharp and clear. However, attention should be paid to the jagged edges of fine details and minor issues around characters, such as the creation of a halo effect, which occurs due to the sharpening imposed by the LG G4 even when the slider is set to the lowest value, which is 0. It is worth noting that this is a change in relation to the LG G3, which did not impose such strong image sharpening, even when the appropriate slider was set to position 0.

TCL C75B has a feature for smoothing tonal transitions, but unfortunately, we cannot praise it. Regardless of the selected level – low or high – tonal transitions in older materials remained visible, as if the feature wasn’t working at all. It’s hard to say anything positive about it, as in practice it seems completely useless.

Image scaling is better. The TV handles it quite decently, although on thinner elements, like branches in the background, you can see slight jaggedness. However, this is not something that significantly hinders everyday viewing.

Unfortunately, a bigger problem turned out to be overscan, or cropping of the image edges. In our tests, it happened that news ticker or other elements close to the edge of the screen were cut off. This is definitely something to pay attention to, especially if we use the TV for watching news programs or content with text on the screen.

The maximum refresh rate that we can set on the LG G4 is 144 Hz. Naturally, this is only possible by connecting the LG G4 to a very powerful PC. Otherwise, we will be operating at a maximum refresh rate of 120 Hz, which is recommended if we primarily want to watch sports or content with high motion dynamics. For those who require high fluidity of 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 from 0 to 10, with each increment affecting the degree of smoothing, so everyone can find their sweet spot.

The LG OLED G4 panel features an average response time of 0.78 ms (which directly results from our measurements), allowing for an incredibly clear image, unattainable by LCD televisions, which have response times of even several milliseconds. This is clearly visible in the "UFO Test" images, showing the absence of any trailing blur behind the object. Furthermore, the LG OLED G4 test showed that the television offers the ability to precisely adjust motion smoothing functionality, allowing users to choose the ideal level of image interpolation. We particularly appreciated this during fast-paced action in video games, where the LG G4 performed exceptionally well, minimising any blurriness. Thanks to OLED technology, this model eliminates so-called ghosting, ensuring that the image remains sharp even in the most dynamic sports or movie scenes.

TCL C75B definitely has something to offer gamers. The television is equipped with a panel that can display images with a refresh rate of 144 Hz in 4K, and even 240 Hz in Full HD. These are really impressive results, especially for a model from the budget range.

On top of that, there are features for improving smoothness and reducing motion blur in films. The "Motion" option allows for precise adjustment of the effect on a 10-point scale, providing significant personalisation possibilities – everyone can set the smoothness to their liking.

The LG G4 television supports all features that make up the HDMI 2.1 standard. During testing, each feature activated without any issues, which allows us to consider the television as designed for gaming. Its performance will certainly be appreciated by both console users and those connecting the LG G4 to a computer. It’s also worth mentioning the proper implementation of the HGIG (HDR Gaming Interest Group) mode, which ensures that games mastered to brightness levels beyond the maximum luminance of the LG G4 will correctly map tones, keeping the game image true to the original.

A nice touch is the presence of a special GameBar that we can bring up at any moment to check game parameters, but most importantly, to change them quickly. More importantly, turning on VRR technology does not degrade contrast, which is often a problem in televisions with local dimming or Mini LED backlighting. Of course, this is thanks to the OLED panel itself, characterised by pixel self-emissiveness. As a journalistic note, we will only mention a slight grey flicker, which, however, is somewhat normal when VRR is enabled.

In summary, the LG G4, like practically all OLED televisions, is an ideal product for all kinds of gaming and online competitions. With full HDMI 2.1 ports with a complete bandwidth of 48 Gbit, features such as VRR, ALLM, G-Sync, FreeSync, or HDR Dolby Vision gameplay will bring a lot of joy.

TCL C75B is undoubtedly a television designed with gamers in mind. It has almost everything needed for even the most demanding console users. With the implementation of full bandwidth HDMI 2.1, the TV supports features like ALLM (automatic low latency mode) and VRR (variable refresh rate) – operating within the full capabilities of the TV, up to 240 Hz in Full HD resolution.

Additionally, the television supports advanced HDR technologies, including Dolby Vision and HGiG, which allows for even better detailing in HDR-optimised games. C75B is also equipped with a very convenient interface for gamers in the form of Game Bar, where you can check all key parameters such as refresh rate, input lag, or picture settings – all just a click away.

In one sentence: C75B is a great choice for gamers, offering a wide range of features that fully enable enjoyment of the capabilities of modern consoles and games.

The input lag of the LG G4 is impressively low in every scenario. Even the most dedicated gamers will surely appreciate the very low input lag at demanding 4K 120 Hz settings with HDR, which is just 5 ms. It's also worth noting that the lag at the same settings, but with Dolby Vision HDR enabled, remains unchanged, which is not as obvious with the competition. Therefore, it deserves the highest rating and recommendation.

The input lag on the TCL C75B is something that truly impresses. With a refresh rate of 144 Hz, the lag is just 9 ms, making the TV's response to our actions on the controller or keyboard practically instantaneous. For 60 Hz, the result is 19 ms – it's not a record low value, but it still falls within a range where the lag is practically unnoticeable during gaming. One could say that the difference is hardly felt, which makes this TV a good choice even for more demanding gamers.

LG G4 paired with a PC performs excellently, thanks to an incredibly low latency of just 5 ms, which is practically instantaneous response between the mouse, eye, and screen. A crucial aspect while working on the screen is the readability of text, which is very good in the case of the tested television.

The RWBG pixel arrangement has no significant impact on the display of fonts or letters, which is a considerable advantage over Samsung's QD-OLED matrices. Users of both Windows-based PCs and macOS will surely be pleased with the performance on the tested LG G4 television.

TCL C75B is quite a good choice for connecting to a computer. With high refresh rates, low input lag, and G-Sync support, the television performs exceptionally well in games – both fast-paced and more demanding ones. The image is smooth, and the response to our actions is quick, which gamers will undoubtedly appreciate.

For office work, the television also holds up well. Text is readable, although on a dark background some imperfections can be noticed – some fonts appear as if they are missing pieces of vertical lines. This may be distracting if we work a lot with documents or text editing. However, if the computer is mainly used for gaming or watching movies, TCL C75B will easily serve its purpose as a monitor. It’s a versatile device that can handle most applications.

The undisputed advantage of OLED screens equipped with MLA technology is their performance when viewing from various angles. To the naked eye, there are no noticeable changes, regardless of where we are watching from. This type of screen maintains consistent brightness, saturation, and white hue, unlike LCD matrices or OLEDs without micro-lens technology (MLA). The only matrices that can match them are those produced by Samsung Displays, using quantum dots, namely QD-OLED.

The viewing angles on the TCL C75B are, unfortunately, very poor. This is a typical compromise with VA panels – better blacks at the expense of off-angle visibility. The picture quickly loses quality when viewed from the side, which is the complete opposite of what IPS panel televisions offer. If we plan to watch the TV mainly head-on, this won't be a big problem. However, with a larger number of viewers sitting at different angles, the picture quality may disappoint.

The glossy coating of the display in LG G4, although it may sound like a downside, is actually quite the opposite. Thanks to it, the LG G4 television maintains very high efficiency and effectively suppresses all reflections, "holding" them only at their source. It's also worth mentioning the quality of black during the day, which in the case of WRGB displays produced by LG Displays is outstanding. OLED MLA displays, despite their many advantages, are somewhat inferior in this case, but still better in the context of competition from Samsung, whose QD-OLED displays fade under light. The combination of brightness at around 500 nits and the glossy coating allows for daytime viewing of the television, unless the user has a living room with large glazing.

TCL C75B performs okay during the day. The satin display somewhat limits reflections, but it's not an ideal solution. Brightness is also an issue – 350 cd/m² is simply not enough for comfortable viewing in a brightly sunlit room.

In less extreme conditions, for example, in a moderately lit room, the TV does alright. However, if the sun starts streaming directly onto the screen in summer, watching can become tiring. It's worth keeping this in mind when choosing this model.

LG uses the well-known proprietary system WebOS, which has been around for many years. The system offers virtually all the essential applications, and those that are missing can be counted on one hand, such as CDA or KODI.

WebOS also provides the highly valued 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 ability to connect headphones via Bluetooth. On a more practical note, WebOS allows us to use both headphones and the TV speaker LG G4 simultaneously, which will certainly be a significant advantage for those with hearing disabilities. 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, allowing for control of all smart devices connected to the home network. For example, the end of a laundry cycle will be signalled by a notification in the top right corner.

In summary, the WebOS system, although less known and with some limitations compared to Android TV, offers stable and fast operation and supports most features that users might need. It is a solid solution for those looking for a simple and effective operating system in a television.

TCL C75B is a television that primarily relies on the Google TV system. The platform offers access to most popular apps, such as Netflix, YouTube, and Prime Video, making it great for watching content from the internet. However, it's worth mentioning that the system can sometimes stutter slightly, which may be noticeable during everyday use.

In terms of smart features, the C75B performs well. Voice control with the help of the built-in assistant works smoothly, and thanks to AirPlay and Miracast, we can easily transfer content from our phone or laptop. Bluetooth allows for effortless connection of headphones, controllers, or other devices.

However, anyone expecting classic television features may be disappointed. There is no option to record programmes on a USB drive or a picture-in-picture (PiP) feature. TCL has been skipping such features for some time, which may not appeal to users who mainly rely on traditional television.

The default file player on the LG G4 performs quite well with most photos, although it's surprising to find a lack of several equally popular ones. It can successfully play videos recorded in virtually all the most popular formats, including Dolby Vision. The only codec that the G4 cannot play is H.266 VVC, although this is currently quite rarely used. However, it's important to note the supported photo formats, of which there are only two: JPEG and PNG. Users of Apple phones 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. Lastly, we should also mention the lack of support for TXT subtitles.

The built-in media player in TCL C75B works really well. It handles most popular image and audio formats with ease. Although there are some shortcomings in the support of certain formats, thanks to Google TV, you can easily install an alternative player that will solve this issue.

The assessment of sound quality is always subjective. However, we must give credit to LG G4 for maintaining a fairly good level of sound clarity. The biggest drawback of the built-in audio system in the television is the low bass range. However, it’s important to look at this from a different perspective — anyone opting for this television will likely have a home theatre system. The key in this case will be broad support for audio codecs, including DTS-HD Master Audio and Dolby Atmos.

The sound on the TCL C75B is really pleasant, especially at lower volume levels. The bass is noticeable and complements the sound well, but only up to about 40% volume. At higher settings, problems start to arise – the bass causes unpleasant vibrations, and the speakers begin to crackle. If we plan to use higher volume levels more frequently, it’s worth considering purchasing a soundbar, as the built-in speakers may not meet more demanding situations.
