LG UR781 vs Samsung The Frame 2025 (LS03F)

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.

The Frame LS03F is a television that can surprise with its brightness. The maximum luminance reaches around 650 nits, which already looks impressive on paper. But as we know, laboratory tests are one thing, and real film scenes are quite another. When watching HDR materials in natural conditions, The Frame 2025 maintains very good results. In most film scenes, the peak brightness remained at around 550–650 nits. This is a sufficient value to feel the difference between standard picture quality and that of HDR – bright highlights, reflections on water, or moonlight are presented clearly and spectacularly.

It is also worth remembering that the LS03F is a QLED television, which translates into solid colour saturation. The coverage of the DCI-P3 colour space reaches about 92%, allowing for vibrant, intense colours in HDR content. This is not the level of top premium models, but for a lifestyle screen, the result truly deserves recognition.

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.

When it comes to image quality straight out of the box, even in Filmmaker mode, which is supposed to be the closest to reference, there were issues. We noticed clear deviations in white balance in both HD and 4K HDR content. The image was heavily skewed towards red and blue, giving the screen a characteristic pinkish tint. This effect was most noticeable in bright scenes – for example, in shots with a lot of white, where neutral light should naturally dominate. At such moments, the screen clearly took on pink tones, which is also visible in the attached comparison photo. As for the brightness characteristics – it wasn’t as bad as one might expect with such colour inaccuracies. The analysis of the gamma curve and EOTF showed a slight brightening of the image compared to the reference, but not enough to drastically ruin the viewing experience.

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 calibration, the movie mode has gained a completely new quality. The issue of the pink tint, which had been clearly visible before, especially in bright scenes, has been effectively eliminated. Colours now look much more natural, and the white balance no longer dominates the rest of the image. It is no longer the same exaggerated "box picture" – everything now has coherence and a cinematic character. Additionally, the tendency of the television to slightly brighten scenes, previously visible in the EOTF curve analysis, has been partially corrected. Of course, this is within the limits of what the design allows without local dimming – one cannot speak of perfect brightness management here. Nevertheless, the final effect was definitely closer to what one might expect from a mode called Filmmaker.

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.

LS03F has been equipped with the NQ4 processor, which is responsible for improving image quality – particularly in lower quality materials. In practice, this works surprisingly well, especially when it comes to older content and recordings with lower resolution. Activating the "noise reduction" function yields noticeable effects. The TV effectively smooths tonal transitions and removes digital noise that can appear in darker areas of the image. Compared to previous generations, there is a clear advancement – previously, this function often smoothed everything too much, including details that it shouldn't remove. In this year's model, smoothing still occurs, but in a much more acceptable manner. Textures of materials, skin, and fabric details are no longer subdued as strongly as before – the image retains more naturalness. However, this does not change the fact that film grain is still removed by the TV, which may not appeal to everyone. On the other hand, it is no longer as aggressive an intervention as in previous models. It is also worth mentioning that the LS03F may struggle with very weak signals – for example, from VHS tape recordings or low-resolution video. In such cases, we noticed slight clipping of the image at the edges – so-called overscan. This can lead to a situation where a small part of the image (e.g., subtitles at the bottom edge) gets cut off.

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.

The new feature in The Frame for 2025 is a display with a refresh rate of 144 Hz. Yes – in a television that is mainly associated with displaying works of art, you can now not only watch Van Gogh but also comfortably play on a console or follow dynamic sports events. This is a definite step towards greater versatility. In the case of Samsung films, as usual in models with a display rate of 120 Hz and above, it allows you to adjust motion smoothness according to your preferences. You can set a more cinematic reproduction while maintaining frame rate or opt for full motion smoothing. The range of options is broad, allowing you to tailor the effect to your own taste – whether the viewing experience is meant to resemble classic cinema or a show on a modern theatre screen.

*this part of the test refers to the LS03FAU model in sizes 55 and 65 inches, which is equipped with a 144Hz panel, while sizes 43 and 50 inches have 60Hz displays, and thus perform much worse in terms of motion smoothness.

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.

As we mentioned earlier – although The Frame is likely to display images and works of art most of the time, Samsung recognised that a Van Gogh enthusiast could just as easily be an avid gamer. And it must be admitted that The Frame 2025 has almost everything needed to become a full-fledged gaming television.

On board, we find support for ALLM (Automatic Low Latency Mode) and Variable Refresh Rate (VRR) thanks to the implementation of one HDMI 2.1 port. The television handles lower resolutions at higher refresh rates effortlessly and features an advanced Game Bar – already known from other Samsung models – which allows for a quick preview and change of the most important gaming-related settings. For this, it earns extra points from us. The proprietary motion smoother Auto Motion Plus Game is also worth mentioning, which – it is worth emphasising – operates without increasing input lag. Samsung remains the only manufacturer that has managed to implement this feature in a practically invisible manner in terms of delays. The effect? Much better fluidity in games, especially those that struggle to maintain a stable 60 frames per second. This solution can realistically improve the gaming experience in more demanding titles – particularly on consoles, which do not always manage full fluidity, especially in AAA games.

As for the downsides – the lack of Dolby Vision is already considered standard in Samsung televisions, so there is not much to particularly criticise here. However, there is a different issue entirely. In the latest version of the Tizen system, the HGiG option has disappeared. Literally – it is not there. This is a significant hindrance when configuring the console for proper HDR content display in games. It is hard to understand why such a decision was made, but one thing is certain – this should be fixed as soon as possible. We are talking about a brand that has set standards for gaming on televisions for years. If HGiG returns – and we hope it will – The Frame LS03F can confidently aspire to be called a genuine gaming television. Not just as a decoration on the wall, but as equipment that truly provides joy in gaming.
