LG OLED G4 vs Samsung The Frame LS03D

LG G4 guarantees an incredibly vivid HDR effect, placing the television among the very best. The equipment of the highest model in the producer's 2024 portfolio with the second generation of micro-lens technology (MLA) has achieved a maximum brightness level of 1474 nits in real scenes. The only area where the product from the Korean manufacturer may lag behind LCD televisions with Mini LED backlighting is during the full-screen scenes featuring a lot of white. If we disregard the latter type of scene, the average result would be even higher. It is also worth mentioning scenes with very fine details, where each one shines at full intensity, which is not as evident in non-OLED televisions. The combination of such brightness and wide coverage of the DCI-P3 palette makes HDR materials more engaging than ever before.

Samsung The Frame LS03D performs really well with brightness. Results of 700 nits make bright elements on the screen look striking and detailed, whether they illuminate the entire screen or appear as small points of light against a dark background. In more demanding scenes, like the fourth sequence from the film Sicario 2, the black levels are average, but we have already discussed this in the section on contrast. As for brightness – the television definitely excels here. An additional advantage is the quantum dot coating, which is QLED technology. Thanks to this, the colour palette coverage 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 was the one we used during our tests. Let's check how its characteristics looked before the calibration process. Looking closely at the white balance first, we can notice a significant dominance of red and green. As a result, the image had a warm yellowish hue. Such characteristics are typically observed in "Cinema", "Filmmaker" or similarly named modes. The effect of this colour balance was clearly visible in both SDR and HDR content, which after switching from "Standard" mode appeared distinctly yellow. Now, let's move on to two graphs that are responsible for the brightness characteristics and consequently the contrast of the image. The first one (Gamma), representing materials with a standard colour palette, performed decently. For most of the time, midtones and bright whites were reproduced very accurately; however, it noticeably lost the darkest details, which merged into a black blob. Conversely, HDR materials, represented by the EOTF curve graph, exhibited a significant drop in contrast due to a strong boost in brightness. The colours themselves also posed a problem, as can be seen on the "ColorChecker" graph, since they were noticeably under-saturated.

Samsung offers several picture modes on its televisions, but undoubtedly the Filmmaker Mode is the one that should provide the most natural representation of content. Unfortunately, as is often the case with mass production, the differences between units can be considerable, and our tested model was not free from 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 images – 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 detracted from its depth.

In 4K HDR content, the white balance was again dominated by red, this time in combination with green. Meanwhile, blue clearly lost intensity, which was easy to notice on the Color Checker palette, where colours began to "drift" in the wrong direction. The EOTF curve, responsible for brightness in HDR content, showed that the television has a tendency to excessively brighten the image, especially in the darkest elements of scenes.

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

The manufacturer has implemented extensive support for the calibration process in its LG televisions for many years. We therefore used 2- and 20-point greyscale adjustments, as well as an advanced CMS (Colour Management System), and got to work. As you can see, thanks to the procedure carried out, each parameter has significantly improved. The use of tools allowed for the achievement of extremely beneficial effects, which include: studio colour reproduction, recovery of details in dark areas of the image, appropriate brightness characteristics, and suitable colour saturation. This brings us as close as possible to the reference image, which is what the film director saw on the preview monitor. It is worth noting that the LG G4 televisions alone allow for even deeper intervention in image quality thanks to the ability to calibrate with 3D LUTs. However, this is a solution recommended only for post-production or graphic studios.

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

So where does the problem arise, given our praise for colour reproduction? Unfortunately, the entire experience is marred by 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 construction limitations. The lack of local dimming means that the television cannot 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 appearance is considerably better than before the settings were corrected.

The tested television did not perform particularly well with materials rich in tonal transitions, as a result of which we could observe a strong posterisation effect. However, there is a partial remedy for this issue. 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 a high effectiveness of smoothing on light colours, although it is low on darker ones. We recommend primarily using the first one, as the other two interfere with the director's intentions by removing film grain.

When watching lower-quality materials, the efficiency of the television during upscaling is extremely important. The image from the tested television is sharp and clear. However, one should pay attention to the jagged edges of fine details and minor issues around characters, such as the creation of halo effects, which occurs due to the sharpening imposed by LG G4 even when the lowest value on the slider, that is 0, is set. It is worth noting that this represents a certain change compared 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 performs with older, lower-quality materials. We already know that the fluidity of tonal transitions is at a very high level here, so we were curious to see how the television would handle smoothing them out.

The noise reduction feature in the "Standard" setting does its job well – tonal transitions are noticeably smoothed out, and at the same time, the image does not lose too much detail. However, it is worth noting that this effect also smooths out film grain, so its use will be a matter of individual preference.

When it comes to image scaling, the television also performed really well. The test chart turned out solid – the model was reproduced correctly, with clear details. The branches in the background, though slightly frayed in places, generally appear natural and do not stand out as imperfections.

The maximum refresh rate that we can set on the LG G4 is 144 Hz. Naturally, this is only possible when the LG G4 is connected 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 high motion dynamics. For those requiring high image fluidity, the manufacturer has implemented a multi-level motion smoother called "TrueMotion". This 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 level affecting the degree of smoothness, allowing everyone to find their golden mean.

The LG OLED G4 panel features an average response time of 0.78 ms (as directly derived from our measurements), enabling an incredibly clear image, unattainable by LCD televisions, which can have response times of several milliseconds. This is perfectly illustrated by the images from the "UFO Test", which show no trailing blur behind the object. Moreover, the LG OLED G4 test revealed that the television offers the ability to precisely adjust the motion smoothing function, allowing users to select the ideal level of image interpolation. We particularly appreciated this during fast-paced actions in video games, where the LG G4 performed exceptionally well, minimising any blurring. Thanks to OLED technology, this model eliminates so-called ghosting, ensuring that the image remains sharp even in the most dynamic sporting or cinematic scenes.

Firstly, it is worth noting that the model we tested in the size of 55 inches, like 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 keeping in mind when making a purchase. As for improving motion fluidity, the television offers a feature called “Picture Clarity”. This is a classic motion smoother that gives users the ability to adjust it using two sliders:

Motion blur reduction – this controls the sharpening of the image in dynamic scenes. The higher the value, the less blur during quick camera movements or moving objects. However, overly aggressive settings may cause the image to become unnatural, appearing like a “soap opera”.

Judder reduction – this slider influences the smoothness of frame playback, particularly in materials with a lower frame rate, such as films (24 fps). Higher settings can smooth motion but may 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 one’s own preferences. It is worth experimenting with the settings to find the perfect balance between fluidity and a natural appearance of the image. We recommend setting them as shown in the picture.

The LG G4 television supports all the features that make up the HDMI 2.1 standard. During testing, each of them activated without the slightest problem, which allows us to consider the television as designed for gaming. Their functionality will surely be appreciated by both console users and those connecting the LG G4 to a computer. It is also worth mentioning the correct implementation of the HGIG (HDR Gaming Interest Group) mode, which ensures that games mastered to brightness levels exceeding the maximum luminance of the LG G4 will correctly map tones, and the game's visuals will remain true to the original.

A nice touch is the existence of a special GameBar, which we can call up at any moment to check game parameters, but most importantly, to change them quickly. More importantly, enabling VRR technology does not degrade contrast, which is very common in televisions that feature local dimming or Mini LED backlighting. Of course, this is thanks to the OLED panel itself, characterised by pixel self-emission. As a matter of editorial obligation, we will only mention a slight grey flicker, which is somewhat normal after enabling VRR.

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

The Frame LS03D in the 2024 version has been equipped with four HDMI ports, but only one of them 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. Here we find ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and HGiG. It is worth highlighting 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 has also not forgotten about features that enhance gaming comfort. Game Bar is an advanced panel for gamers that allows for quick adjustment of screen settings without the need to dig through the television's menu. We can even change the aspect ratio from 16:9 to a panoramic 21:9, which may 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 smoothness enhancer dedicated to games that adds additional frames of animation without significantly affecting input lag. The effect is truly noticeable – the image appears much smoother, which fans of dynamic titles will particularly appreciate.

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