LG OLED C5 vs Samsung The Frame 2025 (LS03F)

LG C5 finally does what we have been waiting for years in the C series – it exceeds 1000 nits of brightness! This is a significant change compared to previous models in the series and also very important – because this is exactly the level of luminance around which most HDR content is now created on streaming platforms. The image finally has the right “glow,” and details in bright areas look as they should even without the use of dynamic metadata. However, there are scenes where the C5, like most OLED televisions, has some issues. Especially when the screen needs to illuminate fully. In our test sequences, such as the bright scene from the movie The Meg, brightness clearly decreases. Don’t get us wrong, this result isn’t bad; it’s more of a reminder that OLED technology still has its limitations. They are getting smaller year by year, but still.

Now, what about the colors? They are very good. Although the C5 does not match the OLEDs with QD-OLED or Tandem RGB panels, the DCI-P3 coverage at 97% and 73% BT.2020 will satisfy even the most demanding viewers. The colors are saturated, natural, and very consistent in HDR materials.

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.

LG C5, like other TVs we tested, was checked in the best possible factory mode – which remains Filmmaker Mode. And here we have good news: in SDR materials, LG once again did a solid job. The white balance and color reproduction straight out of the box are at a very high level. Most errors – both in balance and in the color test (Colour Checker) – did not exceed a ΔE value of 3, which is the threshold above which differences become visible to the naked eye. Such factory settings are something we would like to see in many more TVs!

However, the situation is different for HDR content, which is really what the C series was created for. Here the C5 performs weaker. The excessive presence of blue in the white balance causes the image to appear noticeably cooled – which affects, for instance, unnaturally pale skin tones and somewhat shifted tonality of the entire scene. Fortunately, LG provides very precise calibration tools, and we – as always – took advantage of them.

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.

We must honestly admit – in the case of the LG C5, it took really very little to achieve an almost perfect picture. After calibration, we managed to achieve compliance with reference screens at a level that impresses even compared to much more expensive models. The picture after our adjustment looks exactly as filmmakers and series creators would want it – without color distortions, with natural depth and subtle texture. LG has done a great job this year regarding factory settings and calibration potential. Hats off!

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.

LG C5 handles lower-quality materials really well. One of the main issues older WOLEDs faced was posterization – unwanted "steps" in color transitions. The C5 uses a system feature to smooth these transitions, which works surprisingly effectively. The banding effect is almost completely eliminated, and the image gains consistency. Compared to last year's model, we feel that this feature works slightly weaker – but the good news is that it does not compromise the structure of the image. Film grain, textures, and details remain on the screen – nothing is smoothed out forcefully.

The C5 also does a great job of enhancing the quality of older recordings. Thanks to the α9 Gen6 processor (8th gen), "scaling to 4K" performs really solidly. The image is clear, the details are sharp, and the only minor drawback might be slightly visible jaggedness on some edges. However, there is no issue with overscan here – the image is not artificially cropped or shifted, which is a significant plus and still isn’t a given.

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 C5 is equipped with a 144 Hz panel, and this, combined with the practically zero response time of the OLED pixels, makes it one of the best screens for watching dynamic content. It doesn't matter whether it's sports, fast-paced games, or just action – the image is as sharp as a razor.

And what about movies in 24 frames? LG thought of that too. The built-in "TruMotion" smoother allows you to adjust the image to your own preferences. The "de-judder" slider increases the smoothness in movies, while "de-blur" gently reduces blurring – although to be fair, it is almost imperceptible here anyway.

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.

LG C5 is a television designed with gamers in mind – and there’s not a hint of exaggeration in that. It's hard to find anything to criticize here. We have 144 Hz refresh rate, full support for VRR, ALLM, and up to four HDMI 2.1 ports with full bandwidth of 48 Gb/s. For those who have an Xbox, PS5, Nintendo, and a gaming PC all in one room – there are no limits, everything can be connected without any hassle.

The HDR configuration for gaming is also problem-free. The television properly supports the HGiG mode, which allows for an image consistent with the creators' intentions. For those interested, there’s also Dolby Vision in Gaming mode, though we still recommend HGiG as the most predictable and “pure” version of HDR for games.

The Game Bar is also included, which serves as the “command center” for the gamer. Everything that’s most important, from VRR settings, to picture modes, to frame rate information – is at our fingertips. The interface is simple and readable. It may look like something out of a space simulator, but it serves its purpose and just works; exactly as it should.

C5 is truly a complete package for every gamer.

As we mentioned earlier – although The Frame is likely displaying images and artwork most of the time, Samsung recognized that a Van Gogh enthusiast could just as well be an avid gamer. And it must be admitted that The Frame 2025 has almost everything it needs to become a full-fledged gaming TV.

On board, 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 TV handles lower resolutions at higher refresh rates with ease and features an advanced Game Bar – already known from other Samsung models – which allows for a quick overview and change of the most important gaming-related settings. And for that, it earns extra points from us. The proprietary motion smoothing feature, Auto Motion Plus Game, also deserves a mention, which – and it’s worth emphasizing – works without boosting input lag. Samsung remains the only manufacturer that has managed to implement this feature in a practically unnoticeable way in terms of delays. The result? Much better fluidity in games, especially those that struggle to maintain a steady 60 frames. This solution can genuinely improve gameplay comfort in more demanding titles – especially on consoles that don’t always manage full fluidity, particularly in AAA games.

As for the downsides – the absence of Dolby Vision we already treat as a standard in Samsung TVs, so there’s not much to complain about here. The problem, however, 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 the console for proper HDR content display in games. It’s hard to understand why such a decision was made, but one thing is for sure – it should be fixed as soon as possible. We are talking about a brand that has set standards in gaming on TVs for years. If HGiG returns – and we hope that it will – The Frame LS03F can confidently aspire to the title of a true gaming TV. Not only as a wall decoration but as a device that really provides enjoyment in gaming.

[UPDATE] We have updated our tests of Samsung TVs from the 2025 lineup due to the release of software version 1131, which has restored the critical gaming feature HGiG.
