LG UR781 vs Samsung The Frame 2025 (LS03F)

In HDR mode, the LG UR781 falls short of the brightness expected for high-quality HDR experiences. Tests across multiple panels revealed a brightness of around 200 nits, which aligns more closely with SDR standards. As a result, HDR effects lack the desired impact, with bright and dynamic scenes appearing less striking than they should.

The television also exhibits limitations in colour reproduction under HDR settings. The colours may not appear as intense or rich as those on models that handle wide colour gamuts more effectively, leading to a less vibrant and dynamic image overall. Additionally, the LG UR781 struggles with accurate colour representation in HDR mode, which can result in muted content, particularly during daylight viewing when the image can lose its intensity.

Although the dynamic tone mapping feature helps optimise the image, it does not overcome these shortcomings. For users seeking a truly immersive HDR experience with vivid colours and bright highlights, the LG UR781 may not meet expectations.

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 movie scenes tell a completely different story. When watching HDR content in natural conditions, The Frame 2025 maintains very good results. In most film scenes, peak brightness remained at levels of 550–650 nits. This is enough to feel the difference between standard image quality and that of HDR – bright highlights, reflections on water, and moonlight appear clear and impressive.

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

In Filmmaker Mode, the LG UR781 demonstrates the best factory-calibrated performance but exhibits notable flaws. The primary issue lies in white balance, where the graph indicates a drop in blue levels, resulting in a warmer image with a shift towards yellow tones. This deviation impacts the naturalness of colour reproduction, particularly in scenes with white or neutral backgrounds. The Test Colour Checker confirms that some colours deviate into incorrect shades, leading to a lack of true-to-life representation. This can diminish the realism of film scenes, with certain details appearing in inaccurate colours.

In terms of contrast, the gamma graph reveals a drop to a level of 2.0, below the optimal value of 2.4. This results in darker parts of the image appearing brighter than they should, reducing depth and dynamic range. Additionally, the EOTF curve shows an unnatural spike at the beginning, leading to over-brightness in the brightest areas of the image. This can cause a loss of detail in high-luminance scenes, further impacting the overall image quality.

When it comes to image quality right out of the box, even in Filmmaker mode, which is supposed to be the closest to reference, there were issues. In both HD and 4K HDR content, we noticed noticeable deviations in white balance. The image was heavily skewed towards red and blue, giving the screen a characteristic rosy tint. This effect was most visible in bright scenes – for example, in shots with a lot of white, where neutral light should naturally dominate. In such moments, the screen clearly leaned towards pink tones, which can also be seen in the attached comparison photo. As for brightness characteristics – it wasn't as bad as one might expect given such color inaccuracies. Analysis of the gamma curve and EOTF showed a slight brightening of the image compared to the reference, but not enough to drastically affect the perception of the material.

After calibration, the LG UR781 demonstrates commendable colour reproduction for SDR content. The calibration effectively improves white balance, yielding natural and balanced tones across various scenes. Gamma adjustments contribute to precise detail representation in shadows and highlights, enhancing overall image clarity. This results in a well-rounded performance for everyday use, with solid colour accuracy and well-balanced imagery in SDR mode.

HDR content, however, reveals the TV's limitations. The lack of support for a wide colour gamut restricts the depth and vibrancy that HDR is capable of. The EOTF curve deviates from the ideal, overemphasising details in bright areas, which introduces inaccuracies in colour representation. Tests using the Colour Checker confirm significant errors in colour reproduction. Additionally, the panel's relatively low brightness exacerbates these issues, diminishing the impact of dynamic range effects and causing colours to appear washed out.

While HDR mode highlights the TV's shortcomings, the improvements after calibration, particularly in SDR performance, are significant. Enhanced white balance and gamma adjustments greatly improve the viewing experience, providing more natural and consistent colour reproduction. Compared to its pre-calibration state, the LG UR781 now offers a much better performance for everyday use, especially in standard dynamic range scenarios.

After calibration, the movie mode gained a completely new quality. The issue of pink tint, which had previously been clearly visible, especially in bright scenes, was effectively eliminated. Colors began to look much more natural, and the white balance no longer dominated the rest of the image. It was no longer the same exaggerated “box picture” – everything gained coherence and a cinematic character. Additionally, the tendency of the television to slightly brighten scenes, previously visible in the EOTF curve analysis, was partially corrected. Of course, this was within the limits of what the design allows without local dimming – it’s hard to speak of perfect brightness management here. Nevertheless, the final effect was definitely closer to what one would expect from a mode called Filmmaker.

The tonality smoothing function on the LG UR781 yields mixed results. At the "low" level, it neither enhances image quality nor effectively diminishes film grain, making its impact relatively negligible. Increasing the strength of this function can soften gradations and reduce visible banding, but it risks over-softening the image in certain scenes, which may compromise the overall sharpness and detail.

As for image scaling, the LG UR781 struggles to deliver exceptional performance, particularly with lower-resolution content. The TV employs an artificial sharpness enhancement technique that introduces defined contours to create the illusion of sharper images. While this may appeal to users who prefer pronounced, vivid details, others seeking a more natural and authentic look may find this effect distracting or unrealistic. Ultimately, the perception of these enhancements will depend on personal preferences, with some users valuing the added sharpness and others prioritising natural image quality.

The LS03F is equipped with the NQ4 processor, which is responsible for improving image quality—especially in lower-quality materials. In practice, it works surprisingly well, particularly with older content and recordings with lower resolution. Activating the "noise reduction" feature yields noticeable effects. 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—previously, 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 is done in a much more acceptable manner. Textures of materials, skin, or fabric details are no longer so 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 be to everyone's liking. 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—such as recordings from VHS tapes or video in low resolution. In such cases, we noticed slight clipping of the image at the edges—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 television provides decent motion fluidity for movies, primarily due to its "True Motion" feature. This option lets users fine-tune motion smoothing on a scale from 0 to 10, catering to different viewing preferences. Lower settings preserve a traditional cinematic effect with some judder, while higher settings create a smoother, more theatrical image. Although the latter deviates from the cinematic standard, it may appeal to viewers who prioritise seamless visuals.

However, performance declines when handling dynamic sports content and fast-paced games. Its 60Hz panel limits interpolation capabilities, meaning motion smoothness in movies can be improved, but motion blur cannot be effectively reduced. The absence of support for 120Hz and BFI (Black Frame Insertion) technology exacerbates this, causing fast-moving objects to blur. Moreover, the panel's slower response time further reduces sharpness in rapid scenes, which can be a drawback for gamers and sports enthusiasts seeking clear, fluid visuals in high-speed scenarios.

A novelty in The Frame for 2025 is the panel with a refresh rate of 144 Hz. Yes – in a television primarily associated with displaying artwork, you can now not only watch Van Gogh but also comfortably play on a console or follow dynamic sports action. This is a definite step towards greater versatility. In the case of Samsung films, as usual in models with a 120 Hz panel and above, it allows you to adjust motion smoothness according to your own preferences. You can set a more cinematic representation while maintaining frame rate or opt for full motion smoothing. The range of options is wide, allowing you to tailor the effect to your taste – whether the viewing experience is meant to resemble classic cinema or a presentation on a modern theater panel.

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

The LG UR781 provides several features designed to enhance console gaming experiences but comes with notable limitations. On the positive side, it includes the ALLM (Auto Low Latency Mode) feature, which automatically switches the TV to a low-latency mode, optimising response times for gaming and benefiting fast-paced titles. The television also supports HGiG, ensuring HDR games are displayed enhancing the overall gaming experience. Additionally, the Game Bar feature allows gamers to quickly access and adjust settings during gameplay, offering added convenience. However, there are significant drawbacks. The TV lacks VRR (Variable Refresh Rate), which may result in screen tearing or stuttering, particularly during dynamic scenes. It also does not support Dolby Vision for gaming, limiting HDR picture quality in titles that use this format. The 60Hz panel restricts gameplay to 60Hz, excluding smoother experiences available at higher refresh rates like 1080p@120Hz, 1440p@120Hz, or 4K@120Hz. The absence of G-Sync or FreeSync technology reduces compatibility with systems designed to synchronise the frame rate between the console and TV, potentially affecting gameplay fluidity. The LG UR781 is a functional choice for casual gamers who value affordability and features like ALLM and HGiG. However, it falls short for those seeking advanced gaming features such as high refresh rates, VRR, or Dolby Vision gaming.

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

On board, we find support for ALLM (automatic game 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 without any issues and features an expanded Game Bar – already known from other Samsung models – which allows for quick previewing and changing of the most important gaming-related settings. For this, it earns additional points from us. The proprietary motion smoother Auto Motion Plus Game also deserves special mention, which – and it's worth emphasizing – works without increasing input lag. Samsung remains the only manufacturer that has managed to implement this feature in a practically noticeable way in terms of delays. The result? Much better fluidity in games, especially those that struggle to maintain stable 60 frames. This solution can realistically improve the gaming experience in more demanding titles – especially on consoles that don’t 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's nothing to particularly complain about here. However, the problem is something entirely different. In the latest version of the Tizen system, the HGiG option has disappeared. Literally – it's not there. This is a significant setback when configuring a 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 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 comes back – and we hope that it will – The Frame LS03F can confidently aspire to be a true gaming television. Not just as a decoration on the wall, but as equipment that really provides joy in gaming.
