LG OLED C4 vs Samsung The Frame 2025 (LS03F)

The results of HDR materials are definitely among the better ones. Practically every film significantly exceeds the 700 nits barrier, which allows for a very realistic image. Of course, none of them surpasses the magical thousand, however, the combination of such results along with unlimited contrast and black effectively boosts the visual outcome. The last of the scenes, featuring a fullscreen sun burst, is indeed less bright than the others, although it still represents a respectable level. It's also worth mentioning the excellent coverage of the DCI-P3 colour palette, which will enable the achievement of exceptionally vivid colours.

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.

The best factory mode implemented in the tested television was "Filmmaker". That was the one we used during all tests. This mode, in terms of colour reproduction, turned out to be quite decent, although other flaws effectively detracted from the enjoyment of the viewing experience. Starting with the most basic one, which is white balance, it was easy to notice that this was marked by a dominance of red, which completely altered the characteristics of the picture. We could see a strong yellowing of the whites and a shift of all colours to warmer tones. The gamma, which is a graph as equally important, if not more so, was quite severely reduced, resulting in a significant drop in contrast, except for the start of the graph, where the television insidiously lost details. That’s all regarding SDR materials. Looking closely at films with a wide dynamic range, we can observe exactly the same phenomenon of white balance yellowing as in films with a standard colour palette. The EOTF curve, which replaces the gamma chart for us, is practically perfect and cannot be faulted.

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.

As we mentioned earlier, LG televisions are equipped with advanced tools for carrying out the calibration process. We used them to model the picture in line with what the director envisioned. And without modesty, we must admit that we achieved this phenomenally. Both SDR and HDR materials present a level that clearly indicates this is how a film should look. It's worth taking a look at the colour errors on the "ColorChecker" palette, where practically none of them exceed "1", except for two samples.

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.

Once again, we will take a look at the feature responsible for gentle gradation, but we will also address the one that aims to enhance the quality of lower-quality materials. The default smoothing of tonal transitions, as we could see, was not the worst, but it can be improved further. The function has a slider that allows us to adjust its intensity. We recommend using the former, as it produces very good results and does not blur important details.

Image scaling on LG C4 is quite good, however, it cannot be said to be without flaws. The image is slightly sharper by default, although not in a very noticeable way. While jagged edges of trees can be seen, it is not a major issue when compared to other manufacturers.

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 maximum refresh rate we can set on the LG G4 is 144 Hz. Naturally, this is only possible when connecting the TV to a very powerful PC. Otherwise, we will operate at a maximum refresh rate of 120 Hz, which is recommended if we primarily want to watch sports or content with a lot of motion dynamics. For those who require high fluidity of the image, the manufacturer has implemented a multi-level motion smoother called "TrueMotion". It has been divided into two separate sliders that adjust the sharpness of moving images (De-Blur) and judder (De-Judder). Both sliders can be set in the range of 0 to 10, with each degree affecting the level of smoothing, allowing everyone to find their sweet spot.

The panel of the LG OLED C4 features an average response time of less than 1 ms (which directly results from our measurements), enabling the achievement of an extremely clear image, unattainable for LCD TVs, which can have response times of up to several milliseconds. This is clearly evident in the images from the "UFO Test," which show no trailing blur behind the object.

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.

We can now say that LG C4, like practically every OLED television from the manufacturer, is exceptionally good in terms of cooperation with consoles and PCs. Thanks to the implementation of four full-bandwidth HDMI 2.1 ports at 48 Gbps, the manufacturer has embedded all the features that enhance gaming comfort, including simultaneous support for FreeSync and G-Sync technologies. With such a tandem, players with graphics cards from AMD or nVidia can safely choose C4. However, what should please gamers demanding the highest possible quality the most is the simultaneous implementation of HDR Dolby Vision and HGIG mode. The former is particularly important as it operates with extremely low input lag in all settings.

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 allows for image adjustments for people with visual impairments, which is an incredibly nice touch. Another important piece of information is that when VRR technology is enabled, we won’t experience a drop in contrast. This is, of course, due to the design of the panel and the absence of conventional backlighting. It is, however, normal for shades of grey to flicker slightly, although this is a characteristic feature of this function regardless of the manufacturer and television.

In summary: LG C4, just like all the manufacturer's OLEDs equipped with high-refresh-rate panels and HDMI 2.1 connections, creates a harmonious whole with consoles. In practice, it is a complete television, and if we expect the highest possible efficiency in gaming, C4 will be an ideal choice.

As we mentioned earlier – while The Frame is likely to display images and works of art most of the time, Samsung realised that a Van Gogh enthusiast could equally well be an avid gamer. And it must be said that The Frame 2025 has almost everything it needs to become a full-fledged gaming TV.

Onboard, we find support for ALLM (Auto 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 with ease and has an extensive Game Bar – already known from other Samsung models – which allows for quick viewing and changing of the most important gaming-related settings. And for that, it scores extra points with us. The proprietary motion smoothing technology, Auto Motion Plus Game, also deserves special mention, which – it’s worth emphasising – works without increasing input lag. Samsung remains the only manufacturer that has managed to implement this feature in a virtually unnoticed way in terms of delays. The result? Much better smoothness in games, especially those that struggle to maintain stable 60 frames. This solution can significantly improve gameplay comfort in more demanding titles – particularly on consoles that don’t always maintain full fluidity, especially in AAA games.

As for the downsides – the lack of Dolby Vision is already regarded as standard in Samsung televisions, so there’s not much to critique here. However, the problem is something completely different. In the latest version of the Tizen system, the HGiG option has disappeared. Literally – it’s gone. This is a significant hindrance when configuring consoles for the correct 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 years when it comes to gaming on TVs. If HGiG returns – and we hope it will – The Frame LS03F can confidently aspire to the title of a true gaming television. Not just as a wall decoration but as equipment that truly provides joy in gaming.

[UPDATE] We have updated our tests of Samsung televisions from the 2025 model year due to the release of software version 1131, which restored the key gaming feature, HGiG.
