LG UR781 vs Samsung The Frame LS03D

In HDR mode, LG UR781 unfortunately does not impress with its brightness. In tests on five screens, the television achieved only around 200 nits, which is quite a low value for HDR standards. This brightness is similar to levels typical for SDR, causing HDR effects to be insufficiently pronounced, and the image may appear less impressive, especially in dynamic, bright scenes. In HDR mode, it has certain limitations in colour reproduction. This means that colours may not be as intense and rich as in televisions that manage better with a wide colour gamut. In practice, this can make the image less vibrant and dynamic, and HDR effects will not be as spectacular as one might expect. Additionally, UR781 LG has some issues with accurately reproducing colours in HDR mode, resulting in content that may look less vivid.

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 colour reproduction in LG UR781 in Filmmaker Mode, which although is the best mode available from the factory settings, is not without its flaws. Firstly, the issue is white balance, where the graph shows dips in blue colour levels. This phenomenon results in a shift of hues towards yellow tones, causing the image to appear warmer than it should. Such deviation means that the colours on the screen are not naturally reproduced, which can be particularly noticeable in scenes with a white or neutral background. This can be confirmed by the Test Color Checker, which showed that some colours "shift" into other shades, meaning that the LG UR781 television does not display colours in accordance with reality. This distortion can affect the visual experience, making movie scenes seem less realistic, and details might be displayed in inappropriate colours, negatively impacting the overall image quality.

In terms of contrast, the analysis of the gamma graph revealed drops to a level of 2.0, whereas the optimal value should be 2.4. This means that the television may display darker parts of the image brighter in certain scenes, which reduces their depth and dynamics. Additionally, on the EOTF curve, which is responsible for brightness reproduction, an unnatural spike was observed at the beginning. This phenomenon can result in excessive brightness boost in the brightest parts of the image, leading to loss of detail in very bright scenes.

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.

After calibration, the colour representation in SDR content is quite good. The white balance has been effectively improved, resulting in natural, balanced hues across various scenes. The gamma has also been adjusted, providing more precise detail in the shadows and highlights of the image. As a result, the LG UR781 television performs well in everyday use, offering solid colour quality and clear, well-balanced images in SDR mode.

However, the situation is worse for HDR content. The LG UR781 television does not support a wide colour gamut, which limits the depth and richness of colours that HDR can offer. The EOTF curve deviates from the ideal, resulting in excessive highlighting of details in the bright parts of the image. Unfortunately, this results in significant colour reproduction errors, as confirmed by tests on the Colour Checker. Additionally, the low brightness level of the panel further negatively impacts the quality of HDR images, causing dynamic range effects to be not fully realised, and colours to appear washed out.

Despite some shortcomings in HDR mode, the television has improved significantly after calibration, especially in SDR content. The improvement in white balance and gamma has greatly enhanced image quality, providing a more natural and cohesive colour representation. Compared to its state before calibration, the difference is clear, and the LG UR781 television now offers better performance in everyday use, particularly in the standard dynamic range.

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.

Now let’s address the function of smoothing tonal transitions and its impact on overall image quality. As illustrated in the photo on the left, this function performs exceptionally mediocrely; we selected the "low" level, which does not improve quality but also does not blur the film grain. There is the option to increase the power of this function, which would soften the gradation; however, one must reckon with the fact that the image will be too softened in some scenes.

On the other hand, regarding image scaling, the television does not perform exceptionally, which can be particularly noticeable with lower resolution content. The LG UR781 television applies a slight, artificial sharpness boost, which makes the image appear sharper, but this primarily results from the overlay of artificial contours. For some users, this can be an advantage, as they prefer more vivid, accentuated details. However, this is a subjective matter—such an effect may not appeal to everyone, especially if they desire a more natural look to the image.

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 LG UR781 television offers quite decent smoothness for films, thanks to the "True Motion" option, which allows users to adjust the level of motion smoothing on a scale from 0 to 10. The user can choose whether they want to preserve a more traditional, cinematic effect with subtle judder (lower settings) or prefer a smoother, theatrical image that, although slightly deviating from the cinematic standard, may appeal to many.

In dynamic sports content and games, the LG UR781 television performs worse. The television has a 60Hz panel, which limits its interpolation capabilities to these values; therefore, it can improve fluidity in films but cannot reduce motion blur. Additionally, the lack of support for 120 Hz and BFI (Black Frame Insertion) technology means that quick movements of objects become blurred, and the response time of the panel is too long, negatively affecting clarity in fast scenes. As a result, the television may not meet the expectations of gamers and sports fans who are looking for a smooth, clear image without motion blur.

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.

While gaming on the console, the television LG UR781 offers several important features that can affect the gaming experience, but it also has some limitations. A positive aspect is the presence of ALLM (Auto Low Latency Mode), which automatically optimises picture settings by switching the television LG UR781 into low latency mode, which is beneficial for gamers. The television also supports proper implementation of HGiG, meaning HDR games look as intended by the developers.

Unfortunately, it lacks support for Variable Refresh Rate (VRR), which may result in poorer fluidity of gameplay, particularly in more dynamic games. It also does not support Dolby Vision mode for games, which limits the HDR picture quality in games using this format. The television has a panel with a frequency of 60hz, which means it does not support higher frequencies at other resolutions, such as 1080p@120Hz, 1440p@120Hz, or 4K@120Hz, which is a significant drawback for gamers expecting smoother gameplay at higher resolutions. It also lacks support for G-Sync technology, which limits image synchronisation in games.

However, a positive aspect is the presence of the Game Bar feature, which allows quick access to settings for gamers and makes it easier to adjust picture parameters during gameplay.

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.
