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 comparable to levels typical for SDR, which means that HDR effects are not sufficiently vivid, and the picture may look 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 handle a wider colour gamut better. In practice, this can make the image less vibrant and dynamic, and HDR effects may not be as spectacular as one might expect. Additionally, UR781 LG has some issues with accurate colour representation in HDR mode, which makes content look less lively.

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

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

Colour reproduction in LG UR781 in Filmmaker Mode, which although it is the best mode available from factory settings, is not without its flaws. First and foremost, the issue is with white balance, where the graph shows dips in the blue colour level. This phenomenon results in a shift towards yellow hues, making the image warmer than it should be. Such deviation means that the colours on the screen are not reproduced naturally, which may be particularly noticeable in scenes with white or neutral backgrounds. This can be confirmed by the Color Checker Test, which showed that some colours "escape" into other shades, indicating that the LG UR781 TV does not display colours accurately. This distortion can affect visual experiences, making film scenes seem less realistic and details may be displayed in incorrect colours, negatively impacting overall picture quality.

In terms of contrast, analysis of the gamma graph revealed drops to a level of 2.0, while the optimal value should be 2.4. This means that the TV may display darker parts of the image brighter in some scenes, reducing their depth and dynamism. Additionally, on the EOTF curve, which is responsible for brightness reproduction, an unnatural spike was noticed at the beginning. This phenomenon may result in excessive brightness boosting in the brightest parts of the image, leading to a loss of details in very bright scenes.

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

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

However, the situation is less favourable for HDR content. The LG UR781 TV does not support a wide colour gamut, which limits the depth and richness of colours that HDR can provide. The EOTF curve deviates from the ideal, leading to excessive highlighting of details in the bright areas of the image. Unfortunately, this approach 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 HDR image quality, causing the effects of dynamic range to not be fully realised and colours to appear washed out.

Despite some shortcomings in HDR mode, the TV has significantly improved after calibration, especially in SDR content. The enhancement of white balance and gamma has notably increased image quality, providing a more natural and cohesive colour reproduction. Compared to its pre-calibration state, the difference is clear, and the LG UR781 TV now offers better performance in everyday use, particularly in standard dynamic range.

After calibration, the movie mode gained a completely new quality. The issue of the pink tint, which was previously clearly visible, especially in bright scenes, has been effectively eliminated. Colours started to look significantly more natural, and the white balance no longer dominated the rest of the image. It was no longer the same oversaturated "picture from a box" – everything took on coherence and a cinematic character. Additionally, the tendency of the TV to slightly brighten scenes, previously visible in the EOTF curve analysis, has been partially corrected. Of course, within the limits of what the design allows without local dimming – it's difficult to speak of perfect brightness management here. Nevertheless, the final effect was definitely closer to what one might expect from a mode named Filmmaker.

Let's now address the function of smoothing tonal transitions and its impact on overall picture quality. As illustrated by the photo on the left, this function performs exceptionally mediocre; we chose the "low" level, which does not enhance quality but also does not blur the film grain. There is a possibility to increase the strength of this function, which could soften this gradation, but one must consider that the image will be too softened in certain scenes.

On the other hand, regarding image scaling, the television does not perform outstandingly, which may be particularly noticeable with lower resolution content. The LG UR781 television applies a slight, artificial sharpening boost, making the image appear sharper; however, this mainly results from the application of artificial contours. For some users, this may be an advantage, as they prefer more vivid, pronounced details. However, this is a subjective matter—such an effect may not appeal to everyone, especially if they desire a more natural appearance of the image.

LS03F is equipped with an NQ4 processor, which is responsible for improving image quality – especially in lower-quality materials. In practice, it works surprisingly well, particularly when it comes to older content and recordings with lower resolution. Activating the "noise reduction" feature delivers noticeable results. The television 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 improvement – earlier, this feature often smoothed everything too much, including details that it shouldn't have removed. In this year’s model, the smoothing still occurs, but it happens in a much more acceptable way. Textures of materials, skin, or fabric details are not as heavily muted as before – the image retains more naturalness. However, this does not change the fact that film grain is still removed by the television, which may not appeal to everyone. On the other hand, it's no longer such an aggressive intervention as in previous models. It's also worth mentioning that the LS03F may struggle with very weak signals – for example, from VHS tapes or low-resolution video. In such cases, we noticed slight clipping of the image at the edges – the so-called overscan. This can lead to situations where a small part of the image (e.g., subtitles at the bottom edge) gets cut off.

The LG UR781 TV offers quite decent smoothness for movies, thanks to the "True Motion" option, which allows users to adjust the motion smoothing level on a scale from 0 to 10. Users can choose whether they want to maintain a more traditional, cinematic effect with a slight stutter (lower settings) or prefer a smoother image with a theatrical quality, which, although slightly deviating from the cinematic standard, may appeal to many.

In dynamic sports content and gaming, the LG UR781 TV performs worse. The TV has a 60Hz panel, which limits its interpolation capabilities to these values; therefore, smoothness can be improved in films, but motion blur cannot be reduced. Additionally, the lack of support for 120 Hz and BFI (Black Frame Insertion) technology means that fast-moving objects become blurred, and the panel's response time is too slow, negatively affecting clarity in fast scenes. As a result, the TV may not meet the expectations of gamers and sports fans who are counting on a smooth, clear image without motion blur.

The new feature in The Frame for 2025 is a 144 Hz refresh rate display. Yes – in a television primarily associated with displaying works of art, you can now not only watch Van Gogh, but also comfortably play on a console or follow fast-paced sporting events. This is a significant step towards greater versatility. In the case of Samsung movies, as usual in models with a 120 Hz display and above, it allows you to adjust motion fluidity according to your preferences. You can set a more cinematic reproduction that maintains frame rate or opt for complete image smoothing. The range of options is broad, allowing you to tailor the effect to your tastes – regardless of whether the screening is meant to look like classic cinema or a performance on a modern theatre panel.

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

When playing on a console, the LG UR781 TV offers several significant features that can affect the gaming experience, but it also has some limitations. On the plus side, it includes ALLM (Auto Low Latency Mode), which automatically optimises the picture settings by switching the LG UR781 TV to low latency mode, which is beneficial for gamers. The TV also supports correct implementation of HGiG, meaning HDR games look as intended by the creators.

Unfortunately, it lacks support for Variable Refresh Rate (VRR), which can result in worse gameplay smoothness, especially in more dynamic games. It also does not support Dolby Vision mode for gaming, which limits HDR picture quality in games using this format. The TV has a 60Hz panel, so it does not support higher frequencies at other resolutions, such as 1080p@120Hz, 1440p@120Hz, or 4K@120Hz, which is a significant downside for gamers expecting smoother gameplay at higher resolutions. There is also no support for G-Sync technology, which limits image synchronisation in games.

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

As we mentioned earlier – although The Frame likely displays images and artwork for most of the time, Samsung recognised that a Van Gogh fan could just as easily be an avid gamer. And it must be said that The Frame 2025 has almost everything to become a fully-fledged gaming TV.

Onboard, we find support for ALLM (Auto Low Latency Mode) and Variable Refresh Rate (VRR) thanks to the implementation of a single HDMI 2.1 port. The TV handles lower resolutions at higher refresh rates effortlessly and features an expanded Game Bar – already known from other Samsung models – which allows for quick preview and adjustment of key gaming-related settings. For this, it gets extra points from us. Noteworthy is also the proprietary motion smoother, Auto Motion Plus Game, which – and this is worth emphasising – works without increasing input lag. Samsung remains the only manufacturer that has managed to implement this feature in a practically unnoticeable way regarding delays. The result? Much better fluidity in games, especially those that struggle to maintain a stable 60 frames. This solution can genuinely improve gaming comfort in more demanding titles – particularly on consoles that don’t always manage full fluidity, especially in AAA games.

As for the downsides – the lack of Dolby Vision is already something we consider standard in Samsung TVs, so there’s not much to specifically nitpick here. However, the problem lies elsewhere. In the latest version of the Tizen system, the HGiG option has disappeared. Literally – it’s gone. This is a significant inconvenience when configuring the console for proper HDR content display in games. It's hard to understand why such a decision was made, but one thing is certain – this needs to be fixed as soon as possible. We’re talking about a brand that has set standards for gaming on TVs for years. If HGiG returns – and we hope it does – The Frame LS03F can confidently aspire to be a proper gaming TV. Not only as a decoration on the wall, but as equipment that truly enhances the gaming experience.
