LG OLED G4 vs Samsung The Frame LS03D

LG G4 guarantees an incredibly vibrant HDR effect, placing the television firmly at the top of the rankings. The highest model in the manufacturer's 2024 portfolio, equipped with the second generation of microlens technology (MLA), has achieved a maximum brightness level of 1474 nits in real scenes. The only area where the product of the Korean manufacturer may fall short compared to LCD televisions with Mini LED backlighting is during a full-screen scene featuring a lot of white. If we were to disregard the latter scene, the average result would be even higher. It's also worth mentioning scenes with very fine details, where each one shone at full intensity, which is not as evident in non-OLED televisions. The combination of such brightness and wide coverage of the DCI-P3 color space ensures that HDR materials are more engaging than ever before.

Samsung The Frame LS03D really does well with brightness. Results at the level of 700 nits make bright elements on the screen look impressive and detailed, whether they illuminate the entire screen or appear as tiny points of light on a dark background. In more demanding scenes, like the fourth sequence from the film Sicario 2, the blacks perform moderately, but we have already discussed this in the section on contrast. However, when it comes to brightness – this television definitely holds its own. An additional advantage is the quantum dot coating, which is QLED technology. Thanks to this, the coverage of the colour palette has been improved, although The Frame does not stand out in this regard compared to the competition.

The best factory mode in terms of colour reproduction was "Filmmaker". This is the one we used during our tests. Let's check how its characteristics looked before the calibration process. Taking a closer look at the white balance first, we can notice a significant dominance of red and green colour. As a result, the image had a warm yellow tint. This is the kind of characteristic we usually observe in "Cinema", "Filmmaker", or similarly named modes. The effect of such a colour balance was clearly visible in both SDR and HDR content, which, after switching from "Standard" mode, was distinctly yellowed. Now let's move on to two graphs that are responsible for brightness characteristics, and consequently, image contrast. The first one (Gamma), representing materials with a standard colour palette, performed decently. For most of the time, the midtones and bright whites were represented very accurately, however, it noticeably lost the darkest details which blended into a black patch. On the other hand, HDR materials, represented by the EOTF curve graph, exhibited a significant drop in contrast due to a strong boost in brightness. There was also an issue with the colours themselves as seen on the "ColorChecker" graph since they were noticeably undersaturated.

Samsung offers several picture modes in its televisions, but without a doubt, Filmmaker Mode is the one that should provide the most natural representation of content. Unfortunately, as often happens with mass production, the differences between individual units can be quite significant, and our tested model did not escape a few issues.

In the case of SDR content, the white balance leaned heavily towards red, with a slight boost in blue. This effect was particularly noticeable in comparison photos – for example, in a photograph of a boy whose face was unnaturally flushed. The gamma, or brightness characteristic, also did not perform perfectly – the image was slightly brightened, which robbed it of depth.

In 4K HDR content, the white balance was once again dominated by red, this time combined with green. Meanwhile, blue clearly lost intensity, which could easily be seen on the Color Checker palette, where the colours began to "escape" in the wrong direction. The EOTF curve, responsible for brightness in HDR content, showed that the television tended to overly brighten the image, particularly in the darkest elements of scenes.

Overall, while it did not look terrible, it definitely required correction. Fortunately, Samsung offers extensive calibration options, which provides a chance for a significant improvement in picture quality. Therefore, we proceeded with professional calibration to unlock the full potential of this television.

The manufacturer has been implementing extensive support for the calibration process in their LG televisions for many years. Therefore, we used 2- and 20-point grey scale adjustments along with an advanced CMS (Color Management System) and got to work. As you can see, thanks to the procedure carried out, each of the parameters has significantly improved. The use of tools has resulted in extremely beneficial effects, which include: studio colour reproduction, recovery of details in dark areas of the image, appropriate brightness characteristics, and proper colour saturation. Thus, we have maximised our approach to the reference image, or the one that the film director saw on the preview monitor. It is worth noting that the LG G4 televisions are the only ones that allow for even deeper intervention in image quality due to the capability to calibrate with 3D LUT matrices. However, this solution is recommended only for post-production or graphic studios.

After professional calibration, the Filmmaker Mode showcases its full potential. The white balance in HD content is exemplary – errors at the level of 0.5 indicate almost perfect accuracy in colour reproduction. The image now appears natural, and the colours are exactly as they should be. In 4K HDR content, the effect is not quite as perfect, but it still maintains a really high standard. The colours are vibrant, well-saturated, and the overall image quality is impressive.

So where does the problem lie, given our praise for the colour reproduction? Unfortunately, the entire experience is disrupted by the brightness characteristics. The gamma in HD content looks decent, but in 4K HDR, it’s not as good. The EOTF curve shows that the television excessively brightens certain parts of the image, which is a result of design limitations. The lack of local dimming means that the television is unable to accurately control the differences between the brightest and darkest areas of the screen. This is a barrier that simply cannot be overcome in this model.

Nonetheless, after calibration, Samsung The Frame LS03D offers excellent colour reproduction, particularly in HD content, and the overall look is significantly better than before the settings were adjusted.

The tested television did not perform well with content rich in tonal transitions, resulting in a strong posterisation effect. However, there is a partial remedy for this ailment. The manufacturer has equipped the LG G4 with a smoothing system called "Gentle Gradation," which we can apply at three levels: Low, Medium, and High. Each of these options guarantees quite high smoothing effectiveness on bright colours, though low on darker ones. We recommend primarily using the first one due to the fact that the other two interfere with directorial intentions, removing film grain.

When watching lower-quality content, the efficiency of the television during upscaling is extremely important. The image from the tested television is sharp and clear. However, attention should be paid to the jagged edges of fine details and minor issues around characters, such as the creation of a halo effect, which occurs due to the sharpening imposed by the LG G4 even when the slider is set to the lowest value, which is 0. It is worth noting that this is a change in relation to the LG G3, which did not impose such strong image sharpening, even when the appropriate slider was set to position 0.

It's time to check how Samsung The Frame LS03D copes with older, lower-quality materials. We already know that the smoothness of tonal transitions is at a very high level, so we were curious to see how the TV would handle smoothing them out.

The noise reduction feature in the “Standard” setting does its job well – tonal transitions are noticeably smoothed out, and the image doesn’t lose too much detail. However, it’s worth noting that this effect also smooths out film grain, so its usage will be a matter of individual preference.

When it comes to image scaling, the TV performed really well too. The tested image came out solid – the model was accurately represented, with clear details. The branches in the background, although slightly frayed in places, generally look natural and do not stand out as a flaw.

The maximum refresh rate that we can set on the LG G4 is 144 Hz. Naturally, this is only possible by connecting the LG G4 to a very powerful PC. Otherwise, we will be operating at a maximum refresh rate of 120 Hz, which is recommended if we primarily want to watch sports or content with high motion dynamics. For those who require high fluidity of 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 from 0 to 10, with each increment affecting the degree of smoothing, so everyone can find their sweet spot.

The LG OLED G4 panel features an average response time of 0.78 ms (which directly results from our measurements), allowing for an incredibly clear image, unattainable by LCD televisions, which have response times of even several milliseconds. This is clearly visible in the "UFO Test" images, showing the absence of any trailing blur behind the object. Furthermore, the LG OLED G4 test showed that the television offers the ability to precisely adjust motion smoothing functionality, allowing users to choose the ideal level of image interpolation. We particularly appreciated this during fast-paced action in video games, where the LG G4 performed exceptionally well, minimising any blurriness. Thanks to OLED technology, this model eliminates so-called ghosting, ensuring that the image remains sharp even in the most dynamic sports or movie scenes.

To start off, it’s worth noting that the model we tested in the 55-inch size, along with the 65, 75, and 85-inch versions, is equipped with a 120 Hz panel. Unfortunately, the 43 and 50-inch variants of this series only offer 60 Hz panels, which is worth considering when making a purchase. In terms of improving motion fluidity, the TV offers a feature called “Image Clarity.” This is a classic motion smoother that gives users the ability to adjust using two sliders:

Blur Reduction – this controls image sharpening during dynamic scenes. The higher the value, the less blurring occurs during fast camera moves or moving objects. However, setting it too aggressively can make the image look unnatural and resemble a “soap opera.”

Judder Reduction – this slider affects the smoothness of frame playback, especially in materials with lower frame rates, such as movies (24 fps). Higher settings can smooth out motion but can also lead to excessive “plasticity” of the image.

Both sliders operate on a scale from 0 to 10, allowing for precise adjustment of the effect to personal preferences. It’s a good idea to experiment with the settings to find the perfect balance between fluidity and a natural look for the image. We recommend setting them as shown in the picture.

The LG G4 television supports all features that make up the HDMI 2.1 standard. During testing, each feature activated without any issues, which allows us to consider the television as designed for gaming. Its performance will certainly be appreciated by both console users and those connecting the LG G4 to a computer. It’s also worth mentioning the proper implementation of the HGIG (HDR Gaming Interest Group) mode, which ensures that games mastered to brightness levels beyond the maximum luminance of the LG G4 will correctly map tones, keeping the game image true to the original.

A nice touch is the presence of a special GameBar that we can bring up at any moment to check game parameters, but most importantly, to change them quickly. More importantly, turning on VRR technology does not degrade contrast, which is often a problem in televisions with local dimming or Mini LED backlighting. Of course, this is thanks to the OLED panel itself, characterised by pixel self-emissiveness. As a journalistic note, we will only mention a slight grey flicker, which, however, is somewhat normal when VRR is enabled.

In summary, the LG G4, like practically all OLED televisions, is an ideal product for all kinds of gaming and online competitions. With full HDMI 2.1 ports with a complete bandwidth of 48 Gbit, features such as VRR, ALLM, G-Sync, FreeSync, or HDR Dolby Vision gameplay will bring a lot of joy.

The Frame LS03D in the 2024 version is equipped with four HDMI ports, but only one supports the 2.1 standard with a bandwidth of 40 Gb/s. This is important information if we plan to connect more than one device that requires a 4K@120 Hz signal – for example, two consoles or a console and a gaming PC.

In terms of features for gamers, The Frame truly has a lot to boast about. We have ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate) and HGiG. It’s worth mentioning that HGiG has been very well implemented here, which is particularly important as the television does not support Dolby Vision in games (which is only available on Xbox consoles). In this case, HGiG turns out to be a better standard for gaming.

Samsung hasn't forgotten about features that enhance the gaming experience. Game Bar is an expanded panel for gamers that allows quick adjustment of screen settings without having to dig through the television menu. We can even change the aspect ratio from 16:9 to the panoramic 21:9, which can be a significant advantage for some gamers.

However, Samsung's biggest ace up its sleeve is the Game Motion Plus feature. This is a special smoother dedicated to games that adds additional frames of animation without significantly affecting input lag. The effect is really noticeable – the image seems much smoother, which will be particularly appreciated by fans of dynamic titles.

In summary – Samsung The Frame LS03D is a television that offers a solid set of features for gamers. Although the limitation to one HDMI 2.1 port may be a downside, the rest of the solutions make gaming on this television a truly enjoyable experience.
