LG OLED G4 vs SAMSUNG S95F (TANDEM OLED 83")

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.

The Samsung S95F in the 83-inch variant with a Tandem OLED panel also enchants with its HDR effects. In test movie scenes, such as “Life of Pi” or “Sicario 2,” where smaller light points dominate – stars in the night sky, the glow of the moon, or headlights – the TV easily achieves brightness levels surpassing 2000 nits. This is a result that not long ago seemed unattainable for OLEDs and places this model in the same category as the best Mini-LED constructions.

The limitations of organic panels only emerge in full-screen scenes completely filled with white. In the case of this model, for example, in the final scene of the film The Meg, brightness drops to around 1000 nits – slightly lower than in the smaller QD-OLED variants, where the result hovered around 1400 nits. Nevertheless, we are still talking about an outstanding result, unprecedented in OLED TVs of this size. The colour reproduction is equally impressive. The new Tandem OLED panel nearly catches up to QD-OLED TVs, offering excellent coverage of a wide colour gamut. The results are slightly weaker than those of QD-OLED, but in practice, they still provide an image whose intensity and naturalness of colours are hard to compare with any other television.

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.

The best picture mode right out of the box is undoubtedly Filmmaker Mode. This mode has been present in Samsung televisions for several years and is intended to reproduce the image as faithfully as possible to the creators' vision. In SDR material, it performs reasonably well, though not without flaws. The image is slightly dimmed, and the white balance tends to shift towards red and blue, resulting in a slight pinkish tint on the screen. Average colour errors hover around values of ΔE 3–4, which is on the borderline of what most people can detect with the naked eye.

The limitations are much more apparent with HDR content. Here, a slight excess of blue in the white balance isn't such a big issue – the real obstacle is how the television manages brightness. In many scenes, the image looked as if it had been blown out, and details in the blacks could completely vanish. The final effect didn't do justice to what such a device is capable of, leading to significant colour inaccuracies. It's hard to understand why such a factory characteristic was chosen, as the perception of HDR in this rendition was definitely not what it should have been.

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 calibration, the S95F shows what it can really do. The white balance has been straightened out, and minor inaccuracies have been corrected, making the image in SDR content look nearly exemplary. Colour differences have fallen below the level that the human eye can detect – looking at the screen, one just gets the impression of complete naturalness and harmony of colours.

In HDR, the improvement is equally noticeable. The TV handles brightness much better, and there’s no longer the 'blowing out' of the entire frame. Bright scenes are more controlled, and blacks retain more detail, though sometimes a slight brightening of the overall image can still be noticed. However, this doesn’t change the fact that after calibration, the S95F delivers an image that can confidently be called one of the best on the market – regardless of whether we’re watching movies in SDR or spectacular productions in HDR.

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.

The Samsung S95F model features noise reduction, aimed at improving the fluidity of tonal transitions. Its effectiveness is difficult to call ineffective – on the contrary, it can excessively interfere with the image. Older films or materials of lower quality, such as those from YouTube, take on a soft, smoothed character reminiscent of a painting effect thanks to this feature. The problem is that along with the noise, the natural film grain, which gives the image a cinematic quality, also disappears. Fortunately, the feature does not blur significant details, so its use is more a matter of preference. If someone prefers a slightly polished and smooth image, it’s worth turning it on, but in our opinion, the most sensible setting is “Standard”.

Upscaling leaves a better impression. The S95F efficiently enhances the quality of lower resolution content – even 576p videos look quite good, although minor artifacts in the form of blockiness can be noticed. Overall, the effect is very solid, although when compared to the competition – such as the Sony Bravia 8 (II) or LG G5 – it is noticeable that those models can extract a bit more from the image. However, one inconvenience to remember is that in the case of older films and photos, there is a problem with overscan, which causes a slight trimming of the left edge of the image.

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.

In the case of the 83-inch S95F with a Tandem OLED panel, the fluidity of motion also makes a huge impression. The panel in native 4K resolution offers a refresh rate of 165 Hz, and this combined with organic technology makes games and sport look fantastic. Additionally, the manufacturer has added a motion smoother and a motion blur reduction system, allowing each viewer to customise the picture to their own preferences – whether a more 'choppy', cinematic effect or a smooth, almost theatrical spectacle.

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.

Low motion blur and phenomenal motion fluidity, hallmarks of the OLED panel, are just the warm-up. The Samsung S95F has been designed with gamers in mind – and this is evident at every turn. Four HDMI 2.1 ports with a bandwidth of 40 Gb/s may sound like a compromise on paper, but in practice, neither consoles nor PCs will feel the slightest limitation here. Onboard is a full set of gaming features: variable refresh rate VRR, automatic game mode ALLM, and an excellently implemented HGiG standard, which allows you to enjoy HDR exactly as the creators intended. All this is complemented by Game Bar – an intuitive command centre where you can check and adjust the most important settings in seconds.

Particularly noteworthy is Game Motion Plus, Samsung's proprietary motion smoother. It can add additional fluidity to animations, which can be a lifesaver in games running at 60 frames, where stability doesn't always hold up. Yes, there's no support for Dolby Vision in games, but it's hard to consider this a serious flaw – the manufacturer compensates for this gap with other solutions. The S95F is one of the absolute favourites for the title of the best gaming television on today's market.
