Compare: LG 55 B4 vs TCL A300W NXTVision

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.

At first glance, it is clear that the TCL A300 NXTVision aims to be more than just an ordinary television. It offers an image display mode that – unlike its competitors from Korea, Samsung The Frame – is completely free. Additionally, just like its rivals, it comes with freebies. In the packaging, besides the television, we find extra frames mimicking light wood and a flat wall mount, allowing the television to actually resemble a gallery piece. In terms of everyday use, the standout feature is the Google TV system – extensive, quick, and offering access to a vast number of applications. And if we feel like stepping out of the digital museum and jumping straight into the world of gaming, the A300 can surprise us. Two HDMI 2.1 ports, 144 Hz, VRR, ALLM, and very low input lag ensure that even demanding gamers can feel at home here. Well... perhaps except for those who are sensitive to motion blur – as this remains one of the major issues with this model. There are also downsides. Although the image mode is free – and that is worth appreciating – the quality of the available graphics is clearly lacking compared to what Samsung offers in its paid ART Store. The displayed images resemble photos rather than realistic reproductions of artworks. Unfortunately, the A300 – like the rival Hisense S7NQ – performs poorly here and additionally has certain software issues. The brightness of the television itself also leaves much to be desired – it is the darkest television of the entire "frame trio," which translates to average experiences during the day and limited HDR effect. Nevertheless, the TCL A300 NXTVision is quite a reasonable alternative to Samsung The Frame or S7NQ – especially if we are looking for a cheaper solution without additional fees for access to the "gallery" mode and with an operating system that does not limit us in terms of the number of applications. However, it is essential to remember that this is a proposition with a significant amount of compromises. If we want to save a bit and do not expect top-notch picture quality, then the A300 could be a hit in the picture stakes. Otherwise, it is worth taking a look at its competition.

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 TCL A300, also known as NXTVision, uses a VA panel, so right from the start, one could expect decent contrast. On our test charts, the television indeed showed typical results for this type of panel – in the best case, the contrast reached around 5000:1, which is not a bad result for this segment.

However, it should be noted that the model is not equipped with any local dimming technology, which unfortunately is noticeable in practice. The black levels, though quite deep at times, often lean towards navy blue or grey – especially in darker scenes. In short: for a television without local dimming, it's not bad, but it cannot be compared to models that already have this feature on board.

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.

When it comes to brightness, the TCL A300W is definitely the darkest television among all frame-style models, such as Samsung The Frame or Hisense CanvasTV – and unfortunately, this is immediately noticeable. In our measurements, the peak luminance reached a mere 400 nits, and on test film patterns, this value dropped to 350 nits. This is definitely too little to experience the true “magic” of bright HDR effects. As a consolation – the television is equipped with a PFS LED coating (which is something like QLED), providing very good coverage of a wide colour gamut, both DCI-P3 and BT.2020. In addition, it has full support for all popular HDR formats – HDR10, HDR10+, HLG, and Dolby Vision – which somewhat compensates for the lack of brightness and helps improve the overall perception of content in this quality.

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.

TCL A300 offers several picture modes, but without a doubt, the best is the movie mode. Unfortunately, although it is the best option available, it is not free from errors. In both HD and HDR content, the image has a noticeably too warm hue - it leans slightly towards pink, which is particularly noticeable in scenes with snow. Instead of pure white, we get a pinkish tint that spoils the natural perception of colours.

The management of brightness is also not very good. In the case of older HD material, the image often seems too dark - which is confirmed by the inflated gamma value. Conversely, with HDR content, the effect is the opposite - the image is overly bright, which we observed in scenes from the film Pan. Such a lack of consistency also affects the accuracy of colour reproduction - a test with the ColorChecker showed that many samples clearly deviate from the reference values.

Fortunately, TCL allows for manual adjustment of settings, so we decided to check how the television would perform after our professional calibration. The effects of this adjustment are described below.

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.

After our professional calibration, the TCL A300 has literally received a new lease of life. The image has stopped being too warm, and the colours finally look as they should – which was confirmed by the ColorChecker test, where the colour samples finally started to hit their marks, at least to some reasonable extent. It was also possible to partially correct the brightness management – the image is now more balanced and less "wobbly" between different types of content. Of course, certain limitations cannot be overcome – a slightly noticeable blooming effect is still present, but that is a characteristic of the technology and not something that can be eliminated even after professional settings.

Generally speaking: after calibration, the A300 performs significantly better and gains a completely new quality.

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.

TCL A300 NXTVision is another frame-style television that handles transitions of tones really well. It's hard to find distinct bands or sharp transitions between shades of the same colour – the overall appearance is natural and smooth.

However, it must be admitted that among the three tested models (The Frame and S7NQ), TCL performs the worst in this category. In darker and lighter scenes, slight imperfections can be noticed. Nonetheless, looking at it as a whole, for a television in this price range – it presents itself really solidly. It may not be the best of the bunch, but it maintains a very good level.

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 A300 handles tonal transitions in high-quality films very well, but the question arises – how does it perform with weaker material? The television is equipped with a tonal transition smoothing function, but its effectiveness can be described in one word: "random." In one scene it could work and improve the gradation, but when turned off… the effect remains the same. There is a lack of consistency and predictability.

Image scaling is also not one of A300's strong points. On the test chart, the main character actually looked better than on the raw signal, but with thin lines – such as fonts or background details – there was noticeable jaggedness and aliasing. On the positive side, the television does not crop the image and has no problems with overscan, but the overall quality of scaling is rather average.

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.

The TCL A300 is equipped with a 144 Hz panel, which should immediately satisfy practically everyone – both gamers and sports fans. The motion is smooth and the image is clear even during fast-paced scenes. Additionally, the television offers motion enhancement functionality called "Motion," where we find two sliders on a 10-point scale. These allow you to adjust the effect to your own preferences – from a classic, cinematic look with visible frames to a very smooth (though somewhat unnatural) image reminiscent of soap opera effects. This way, everyone can find a setting that suits them.

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.

TCL A300 is a television designed not only to transport us to a digital art museum but also to a full-fledged gaming world. Here, we find practically everything one could expect from gaming equipment: two full-bandwidth HDMI 2.1 ports, 144 Hz refresh rate, VRR support, and ALLM.

The proper implementation of the HGIG mode also deserves praise – something that competitor Hisense sometimes struggles with. The television easily handles lower resolutions (e.g., Full HD) while maintaining high refresh rates, which older console or PC owners will appreciate.

In addition, there is an attractive and clear GameBar that facilitates quick access to settings for gamers. The A300 is really well-prepared for top-level gaming – it's just a shame that issues with smearing slightly tarnish its overall image as a gaming device.

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.

In terms of input lag, the TCL A300 performs really well. Values below 10 ms at a refresh rate of 120 Hz are something many gamers dream of – such low lag is practically unnoticeable, both during everyday gaming and in more demanding e-sports titles. One might criticise the result of 23 ms in Dolby Vision mode at 60 frames, but it is still a sufficiently low value that it's hard to have serious objections. In this category, the A300 really excels.

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.

If we plan to use the TCL A300 as a monitor for a computer, we may be pleasantly surprised. The television performs really well in this role. It is equipped with a 144 Hz panel, supports G-Sync, and, as we have already mentioned, offers very low input lag, so gaming on it with a connected PC is a pure pleasure.

Working with text is also possible, though with some limitations. The TCL A300 has slight issues displaying dark fonts and thin lines – this stems from the subpixel structure, which in everyday use can be somewhat bothersome, although it looks better in photos than in reality.

The television supports chroma 4:4:4, but only up to 120 Hz. Therefore, we have indicated that this feature is available, but with a limitation – if we care about perfectly readable fonts, it is advisable to stick to a refresh rate of 120 Hz. At 144 Hz, the sharpness of the text may suffer slightly.

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.

The viewing angles on the TCL A300 NXTVision are – let's be honest – mediocre. The television is equipped with a VA panel, which inherently has rather limited angles and unfortunately this is evident here. The video below speaks for itself – even a slight deviation from the axis results in a noticeable drop in contrast and colour saturation. It's a shame that this is yet another frame-style television that has done absolutely nothing about it. After all, we don't always have the opportunity to sit perfectly straight on – especially if the device is also intended to serve a decorative function in the living room.

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.

The TCL A300 NXTVision is equipped with a matte panel very similar to the one found in one of its Chinese competitors – the Hisense S7NQ model. Such a surface handles reflections fairly well, although it must be said that it performs worse than Samsung's The Frame, which offers a significantly higher level in this regard. As is often the case with matte displays, blacks lose their depth during the day and appear more gray than black – and this is no different here. Unfortunately, the fact that the A300 is the darkest television of the three tested does not help either. As a result, it has a real problem standing out in brightly lit rooms.

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.

The TCL A300 is a television styled to resemble a painting, which can successfully masquerade as a work of art during everyday use, hanging on the wall. It is equipped with a special image display mode, additional frames in a light wood tone, and a flat wall mount that allows the television to be hung like a true picture – flush against the wall.

A significant advantage of the image mode is that it is completely free. We have access to dozens of works from which we can choose the one to be displayed in standby mode – instead of a black screen, the picture we selected remains on the wall. The quality of the graphic reproductions is decent, but it must be admitted that it clearly falls short of that from the Samsung ART Store. Although access to images there is paid, the quality of the scans is significantly better – you can see the texture of the paint, the canvas, and the details. In the TCL A300, it resembles high-quality photographs more than realistic reproductions of artworks. Additionally, the implementation of the image mode in the system leaves much to be desired. For example – if we set the brightness in image mode to 10%, that same value automatically transfers to the normal viewing mode, where we could comfortably set the brightness to 50% or even 100%. This works in the opposite direction too – when we set the brightness to 100% in normal mode, switching to gallery mode displays the images with that same maximum brightness, shining too intensely and losing the entire effect of a “picture on the wall.” These are minor but annoying errors that can ruin the experience of what was intended to be visually subtle and elegant.

Moving on to more classic features – the A300 runs on the Google TV system, which currently offers by far the largest selection of applications (the full list available below). The well-functioning voice assistant with support for the Polish language is also a major plus. As standard – as in most TCL televisions – the USB recording function or picture-in-picture (PiP) mode is missing.

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 built-in player in the TCL A300 works as it should – most popular video and photo files play without any issues. There is a lack of support for the HEIC format from Apple (which is quite common in many televisions), but most users still use AirPlay, so this shouldn't be a major problem. If someone is not satisfied with the default player, the Google TV system offers considerable options – it's easy to install an alternative app that better suits our tastes. Nevertheless, it must be acknowledged that the factory solution is entirely sufficient for everyday use.

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.

When it comes to sound, the TCL A300W – like its competitors – plays quite... flat, after all, we are talking about a super flat television. For everyday watching of news or series, this level is entirely sufficient, but during film screenings, we may clearly miss depth and space. On the plus side, it is worth noting that the television supports both Dolby Atmos and the increasingly rare DTS:X – which offers more options when connecting an external audio system. It is also worth mentioning that the A300 PRO model has been equipped with a dedicated, flat soundbar. And not just any soundbar – it performs better than most of the televisions we have tested.
