Compare: LG 55 B4 vs Samsung The Frame LS03D

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.

Samsung The Frame LS03D (2024) is not an ordinary television that you can place in the corner and forget after two days. Here, it is immediately evident that the manufacturer has focused on something more than just playing films. First, the “Art” mode captures attention – with just a few clicks, we can turn The Frame into a digital gallery, displaying works that, in combination with the matte screen, truly resemble a real framed painting. And speaking of the frame, we have the option to customise its colour to perfectly match our interior. Additionally, the package includes a wall mount, allowing the television to hang almost “flush”, which further enhances the impression of engaging with an image rather than a typical screen. The matte screen provides excellent protection against reflections, which together with high brightness (650 cd/m²) works well in bright sunlight. Furthermore, we have a VA panel with quite decent contrast and a refresh rate of 120 Hz, so when watching sports or playing dynamic titles, everything appears smooth and pleasant to the eye. If we also add a gaming features package – VRR, ALLM and HGiG – it’s clear that Samsung has also considered console and PC enthusiasts. As a result, Samsung The Frame can be both a picturesque decoration for the living room and a reasonably effective gaming monitor. The mentioned One Connect is another useful gadget – it allows us to hide all the cables in one place, with a thin wire connecting the television to this magical box. If we like order, this solution is made for us. Another advantage is the Tizen system – easy to use, fast, and full of applications. We may not find absolutely everything in it (e.g. the Tidal app), but it still provides a wide range for exploring various streaming platforms. Of course, there’s no rose without thorns. The lack of local dimming is noticeable in dark scenes, where blacks become less pronounced. We also need to remember that there is only one HDMI 2.1 port here, so if we want to connect more devices at 4K and 120 Hz, we may feel limited. Additionally, the viewing angles are rather average, so it’s better for the most important viewer (that is us) to sit directly in front of the television. For fans of Dolby Vision, this will also not be an ideal choice, as The Frame LS03D only supports HDR10 and HDR10+. Furthermore, the sound – as with most slim televisions – is mediocre, so it’s worth considering a soundbar if we care about clearer bass and a bit deeper sound. Despite these weaker points, The Frame still makes a great impression. It is striking, stylish, and versatile – perfect for watching the latest hits as well as displaying reproductions of paintings on the wall. If we value an unusual appearance, high brightness, and at the same time want to play with low input lag, this model will be a perfect choice. And although it is not a leader in terms of value for money nor a technological “monster” in terms of picture quality, it has something that simply makes it likable. It is a device that stands out with its unique character and can blend into any interior, attracting attention both in television mode and as a digital art gallery.

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.

Samsung The Frame uses a VA panel, which in itself provides quite high contrast. In our tests, the results oscillated around 4000–5000:1, which will be more than enough for most users. However, the lack of local dimming is noticeable, especially on more demanding test slides. In dark scenes, it can be observed that black has a subtle hint of navy blue. During the day or in a well-lit room, this will not be an issue, but during an evening viewing, more discerning viewers may feel a slight deficiency.

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.

Samsung The Frame LS03D performs really well with brightness. Results of 700 nits make bright elements on the screen look striking and detailed, whether they illuminate the entire screen or appear as small points of light against a dark background. In more demanding scenes, like the fourth sequence from the film Sicario 2, the black levels are average, but we have already discussed this in the section on contrast. As for brightness – the television definitely excels here. An additional advantage is the quantum dot coating, which is QLED technology. Thanks to this, the colour palette coverage has been improved, although The Frame does not stand out in this regard compared to the competition.

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.

Samsung offers several picture modes on its televisions, but undoubtedly the Filmmaker Mode is the one that should provide the most natural representation of content. Unfortunately, as is often the case with mass production, the differences between units can be considerable, and our tested model was not free from a few issues.

In the case of SDR content, the white balance leaned heavily towards red, with a slight boost in blue. This effect was particularly noticeable in comparison images – for example, in a photograph of a boy whose face was unnaturally flushed. The gamma, or brightness characteristic, also did not perform perfectly – the image was slightly brightened, which detracted from its depth.

In 4K HDR content, the white balance was again dominated by red, this time in combination with green. Meanwhile, blue clearly lost intensity, which was easy to notice on the Color Checker palette, where colours began to "drift" in the wrong direction. The EOTF curve, responsible for brightness in HDR content, showed that the television has a tendency to excessively brighten the image, especially in the darkest elements of scenes.

Overall, while it did not look terrible, it definitely required adjustment. Fortunately, Samsung offers extensive calibration options, which provides the chance for a significant improvement in image quality. Therefore, we proceeded with professional calibration to extract the full potential from this television.

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 professional calibration, the Filmmaker Mode shows its full potential. The white balance in HD content is exemplary – errors at the level of 0.5 indicate almost perfect colour reproduction accuracy. The image now looks natural, and the colours are precisely as they should be. In 4K HDR content, the effect is not quite as perfect, but it still maintains a really high level. The colours are vibrant, well-saturated, and the overall picture quality can be impressive.

So where does the problem arise, given our praise for colour reproduction? Unfortunately, the entire experience is marred by brightness characteristics. The gamma in HD content looks decent, but in 4K HDR it's not as good. The EOTF curve shows that the television excessively brightens certain parts of the image, which is a result of construction limitations. The lack of local dimming means that the television cannot accurately control the differences between the brightest and darkest areas of the screen. This is a barrier that simply cannot be overcome in this model.

Nonetheless, after calibration, Samsung The Frame LS03D offers excellent colour reproduction, particularly in HD content, and the overall appearance is considerably better than before the settings were corrected.

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.

This is one of the best televisions we have had the opportunity to test in terms of the smoothness of tonal transitions. Any potential imperfections are so minor that you really have to strain your eyes to notice them. They are subtle enough that we only deducted a symbolic fraction of points in this category. Without a doubt, this is one of the greatest advantages of this model. It is possible that such a good effect is partly due to the matte screen coating, which gently masks any irregularities in the colour gradation. The smoothness of tonal transitions in Samsung The Frame LS03D is at a level that will satisfy even exceptionally demanding users. Kudos to LS03D!

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.

It’s time to check how Samsung The Frame LS03D performs with older, lower-quality materials. We already know that the fluidity of tonal transitions is at a very high level here, so we were curious to see how the television would handle smoothing them out.

The noise reduction feature in the "Standard" setting does its job well – tonal transitions are noticeably smoothed out, and at the same time, the image does not lose too much detail. However, it is worth noting that this effect also smooths out film grain, so its use will be a matter of individual preference.

When it comes to image scaling, the television also performed really well. The test chart turned out solid – the model was reproduced correctly, with clear details. The branches in the background, though slightly frayed in places, generally appear natural and do not stand out as imperfections.

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.

Firstly, it is worth noting that the model we tested in the size of 55 inches, like the 65, 75 and 85-inch versions, is equipped with a 120 Hz panel. Unfortunately, the 43 and 50-inch variants of this series only offer 60 Hz panels, which is worth keeping in mind when making a purchase. As for improving motion fluidity, the television offers a feature called “Picture Clarity”. This is a classic motion smoother that gives users the ability to adjust it using two sliders:

Motion blur reduction – this controls the sharpening of the image in dynamic scenes. The higher the value, the less blur during quick camera movements or moving objects. However, overly aggressive settings may cause the image to become unnatural, appearing like a “soap opera”.

Judder reduction – this slider influences the smoothness of frame playback, particularly in materials with a lower frame rate, such as films (24 fps). Higher settings can smooth motion but may also lead to excessive “plasticity” of the image.

Both sliders operate on a scale from 0 to 10, allowing for precise adjustment of the effect to one’s own preferences. It is worth experimenting with the settings to find the perfect balance between fluidity and a natural appearance of the image. We recommend setting them as shown in the picture.

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 Frame LS03D in the 2024 version has been equipped with four HDMI ports, but only one of them supports the 2.1 standard with a bandwidth of 40 Gb/s. This is important information if we plan to connect more than one device that requires a 4K@120 Hz signal – for example, two consoles or a console and a gaming PC.

In terms of features for gamers, The Frame truly has a lot to boast about. Here we find ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and HGiG. It is worth highlighting that HGiG has been very well implemented here, which is particularly important as the television does not support Dolby Vision in games (which is only available on Xbox consoles). In this case, HGiG turns out to be a better standard for gaming.

Samsung has also not forgotten about features that enhance gaming comfort. Game Bar is an advanced panel for gamers that allows for quick adjustment of screen settings without the need to dig through the television's menu. We can even change the aspect ratio from 16:9 to a panoramic 21:9, which may be a significant advantage for some gamers.

However, Samsung's biggest ace up its sleeve is the Game Motion Plus feature. This is a special smoothness enhancer dedicated to games that adds additional frames of animation without significantly affecting input lag. The effect is truly noticeable – the image appears much smoother, which fans of dynamic titles will particularly appreciate.

In summary – Samsung The Frame LS03D is a television that offers a solid set of features for gamers. While the limitation to one HDMI 2.1 port may be a downside, the rest of the solutions makes gaming on this television a truly enjoyable experience.

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 latency, The Frame LS03D is truly impressive. 13 ms for 60 Hz content and 8 ms for 120 Hz are results that will satisfy even the most demanding gamers. Such low values mean that responses to controller movements are almost instantaneous. In dynamic games, such as shooters or racing games, every fraction of a second matters – this is where Samsung LS03D 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.

Using a computer on The Frame is truly a pleasant experience. The fonts are clear and well-rendered thanks to support for chroma 4:4:4. There is no blurring or fuzziness, which often occurs in cheaper televisions. Of course, if someone looks very closely at small text, they may notice minimal imperfections, but that's really a minor detail that doesn't interfere with everyday tasks. It is also suitable for PC gaming. The 120 Hz panel, support for G-Sync, and really low input lag ensure that games run smoothly and without delays.

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 of the Samsung The Frame LS03D are average, which is typical for a VA panel. Here lies a bit of a problem – this television is supposed to serve as a display for images and works of art, which are not always viewed head-on. When viewed at an angle, colours begin to lose their intensity, and blacks turn into shades of grey. This is not at a level that completely ruins the experience, but if the television is to be placed where it will often be viewed from the side, the effect may be noticeable. It's a shame, as better viewing angles would be a significant advantage for a television of this purpose.

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.

Samsung The Frame is equipped with a matte panel that excels at suppressing direct light reflections. This means that even in a brightly lit room, the image remains clear, and reflections do not interfere with viewing. Of course, as is often the case with matte finishes, there is a trade-off – colours lose some intensity, and black may appear more washed out during the day. Fortunately, the television compensates for this with a brightness level of 650 cd/m². This ensures that the image is bright, clear, and well visible even in a heavily sunlit room.

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.

Samsung The Frame LS03D is a television that stands out from other models and is difficult to describe in a traditional way. Of course, it includes all the standard Smart TV features thanks to the Tizen system. The system operates responsively, is comprehensive, and offers a wide selection of applications. The remote control supports voice commands in Polish, and additional devices can be connected via Bluetooth – just like in many other televisions. But that's not the essence of this model.

The greatest strength of Samsung The Frame is its design. The "Art" mode allows you to display thousands of high-resolution images, which, combined with a matte display, look truly exceptional. The effect is surprisingly realistic and hard to compare with any other television.

The bezels may not be the thinnest on the market, but you can customise them in terms of colour and style to perfectly blend with your interior. (Sold separately) And while the bezels themselves are not ultra-thin, the entire construction is sleek and elegant. The wall mount, which is included (its value is approximately £80), also deserves special attention. With it, the television can be mounted practically flat against the wall, with no gap, which further emphasises the "picture" effect.

And what about the cables? Samsung thought of that too. The Frame has been equipped with a One Connect module – an external box where all devices are connected. Only one nearly invisible cable runs to the television, which transmits both the signal and power. The box can be easily hidden in a cabinet or behind furniture, which means nothing disrupts the aesthetics of the interior.

Samsung The Frame LS03D is more than just an ordinary television – it is a thoughtfully designed decorative element that combines the modern functionality of Smart TV with exceptional design and practical solutions. Although it lacks typical features such as USB recording or PiP, it is not a model created with a classic approach to television in mind. LS03D the frame is a television that is easy to love for its innovation, originality, and how wonderfully it fits into any interior.

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 media player in Samsung The Frame handles most popular video and audio formats without major issues. Video files, even those with subtitles that we have added, play smoothly and without interruptions. The same goes for audio files – here too, there are no significant surprises. The situation is somewhat worse when it comes to handling photo formats. The built-in player has certain limitations and does not support all possible types of graphic files. However, nowadays, most people use wireless photo transfer, so for many users, this will not be a major problem.

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.

The sound on the Samsung The Frame is… well, quite average. The slim design of the television, while looking impressive, doesn’t allow much space for decent speakers. As a result, the sound is flat and lacks dynamism – exactly like most televisions in this category. Samsung is clearly aware of this, as it offers a special series S of soundbars, specifically created for its "lifestyle" televisions, which includes the The Frame.
