LG 55 B4 vs Samsung The Frame LS03D

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

Samsung The Frame LS03D really does well with brightness. Results at the level of 700 nits make bright elements on the screen look impressive and detailed, whether they illuminate the entire screen or appear as tiny points of light on a dark background. In more demanding scenes, like the fourth sequence from the film Sicario 2, the blacks perform moderately, but we have already discussed this in the section on contrast. However, when it comes to brightness – this television definitely holds its own. An additional advantage is the quantum dot coating, which is QLED technology. Thanks to this, the coverage of the colour palette 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," and we used it throughout the entire testing procedure. We must admit that the unit we received straight out of the box had quite decent colour reproduction. The biggest issue in both SDR and HDR content turned out to be white balance. In the former, there was a strong dominance of red, resulting in a noticeable yellow tint in the displayed image, particularly evident on skin tones and whites. In high-quality materials, this colour was also pronounced, but due to a lack of blue, there were also signs of green visible. Besides these shortcomings, we also encountered issues with greyscale and the colours themselves.

Samsung offers several picture modes in its televisions, but without a doubt, Filmmaker Mode is the one that should provide the most natural representation of content. Unfortunately, as often happens with mass production, the differences between individual units can be quite significant, and our tested model did not escape 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 photos – 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 robbed it of depth.

In 4K HDR content, the white balance was once again dominated by red, this time combined with green. Meanwhile, blue clearly lost intensity, which could easily be seen on the Color Checker palette, where the colours began to "escape" in the wrong direction. The EOTF curve, responsible for brightness in HDR content, showed that the television tended to overly brighten the image, particularly in the darkest elements of scenes.

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

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

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

So where does the problem lie, given our praise for the colour reproduction? Unfortunately, the entire experience is disrupted by the 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 design limitations. The lack of local dimming means that the television is unable to 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 look is significantly better than before the settings were adjusted.

In this paragraph, we will take another look at the tonal transition smoothing feature, but we will also check how the TV handles lower quality material. As we have managed to check, the setting responsible for smooth gradation works quite effectively, although it has its weaker moments. While the feature works well with SDR content, it becomes less useful with HDR content. Even at the lowest of options, it blurs essential details, so we advise against using it.

The image scaling on LG B4 is rated fairly moderately positively. Although there is no edge splitting, 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 copes with older, lower-quality materials. We already know that the smoothness of tonal transitions is at a very high level, so we were curious to see how the TV would handle smoothing them out.

The noise reduction feature in the “Standard” setting does its job well – tonal transitions are noticeably smoothed out, and the image doesn’t lose too much detail. However, it’s worth noting that this effect also smooths out film grain, so its usage will be a matter of individual preference.

When it comes to image scaling, the TV performed really well too. The tested image came out solid – the model was accurately represented, with clear details. The branches in the background, although slightly frayed in places, generally look natural and do not stand out as a flaw.

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

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 TVs, which have response times of even several milliseconds. This can be clearly seen in images from the "UFO Test", showing no trace of blur trailing behind the object.

To start off, it’s worth noting that the model we tested in the 55-inch size, along with 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 considering when making a purchase. In terms of improving motion fluidity, the TV offers a feature called “Image Clarity.” This is a classic motion smoother that gives users the ability to adjust using two sliders:

Blur Reduction – this controls image sharpening during dynamic scenes. The higher the value, the less blurring occurs during fast camera moves or moving objects. However, setting it too aggressively can make the image look unnatural and resemble a “soap opera.”

Judder Reduction – this slider affects the smoothness of frame playback, especially in materials with lower frame rates, such as movies (24 fps). Higher settings can smooth out motion but can 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 personal preferences. It’s a good idea to experiment with the settings to find the perfect balance between fluidity and a natural look for the image. We recommend setting them as shown in the picture.

The LG B4 television is equipped with four full-fledged HDMI 2.1 ports with a full bandwidth of 48Gbps. All functions corresponding to this standard activated without any issues, and throughout the entire testing procedure, they caused no problems. The combination of such extensive functionality and low input lags leads us to say that the tested television is truly designed for gaming. This is not surprising, considering that the manufacturer has always placed great emphasis on this. Therefore, we can enjoy both a properly implemented HGIG mode and gameplay in Dolby Vision with low latency. Such a tandem will surely attract the attention of all passionate gamers for whom quality is the most important.

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

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

The Frame LS03D in the 2024 version is equipped with four HDMI ports, but only one 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. We have ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate) and HGiG. It’s worth mentioning 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 hasn't forgotten about features that enhance the gaming experience. Game Bar is an expanded panel for gamers that allows quick adjustment of screen settings without having to dig through the television menu. We can even change the aspect ratio from 16:9 to the panoramic 21:9, which can 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 smoother dedicated to games that adds additional frames of animation without significantly affecting input lag. The effect is really noticeable – the image seems much smoother, which will be particularly appreciated by fans of dynamic titles.

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