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

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.

The Samsung S95F in the 83-inch variant with a Tandem OLED panel also manages to enchant with HDR effects. In test film 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 television effortlessly achieves brightness values exceeding 2000 nits. This is a result that not long ago seemed unattainable for OLEDs and positions this model alongside the best Mini-LED constructions.

The limitations of organic panels only reveal themselves in full-screen scenes filled entirely with white. In the case of this model, for instance in the final scene from the film The Meg, brightness drops to around 1000 nits – a bit lower than in the smaller QD-OLED variants, where the result hovered around 1400 nits. Nevertheless, we are still talking about a remarkable result, unprecedented in OLED televisions of this size. The colour reproduction is equally impressive. The new Tandem OLED panel virtually catches up with QD-OLED televisions, offering excellent coverage of a wide colour gamut. The results are slightly weaker than with 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 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.

The best picture mode straight out of the box is undoubtedly Filmmaker Mode. This is a mode that has been available 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, although not without faults. The image is slightly subdued, and the white balance tends to shift towards red and blue, resulting in a slight pinkish tint on the screen. The average colour errors hover around a value of ΔE 3–4, which is at the limit of what most people can discern with the naked eye.

Much more pronounced are the limitations when it comes to HDR content. Here, a slight excess of blue in the white balance is not such a big problem – the real obstacle is the way the television manages brightness. In many scenes, the image appeared as if it had been overexposed, and details in the blacks could completely disappear. The final effect did not reflect what the hardware of this class is capable of and led to significant colour errors. It's hard to understand why such a factory characteristic was chosen, as the HDR reception in this version was definitely not what it should have been.

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 calibration, the S95F shows what it is truly capable of. The white balance has been corrected and minor inaccuracies adjusted, resulting in an almost exemplary image for SDR content. The colour differences have dropped below the level that the human eye can perceive – looking at the screen gives a sense of complete naturalness and colour coherence.

In HDR, the improvement is equally noticeable. The TV performs much better with brightness, eliminating the issue of "blowing out" the entire frame. Bright scenes are more controlled, and blacks retain more detail, although there can still be a slight brightening of the image as a whole. However, this does not change the fact that after calibration, the S95F delivers an image that can comfortably be called one of the best on the market – regardless of whether we are watching movies in SDR or spectacular productions in HDR.

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.

In the Samsung S95F model, there is a noise reduction feature aimed at improving the smoothness of tonal transitions. Its operation can hardly be called ineffective – on the contrary, it can overly interfere with the image. Older films or materials of poorer quality, such as those from YouTube, acquire a soft, smoothed character thanks to it, reminiscent of a painting effect. The problem is that along with the noise, the natural film grain disappears, stripping the image of its cinematic character. Fortunately, the feature does not blur significant details, so its use is more a matter of taste. If someone prefers a slightly polished and smooth image, it is worth enabling, but in our opinion, the most sensible setting is “Standard”.

A better impression is left by the upscaling. The S95F efficiently enhances the quality of lower resolution content – even 576p video looks quite good, although minor artifacts in the form of blockiness can be noticed. Overall, the effect is very solid, although when compared to competitors – 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, it is worth remembering one inconvenience: with older films and photos, there is an overscan issue that causes a slight cutting off 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 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.

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

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.

Low smearing and phenomenal motion fluidity, which are the hallmarks of OLED displays, 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 experience the slightest limitation here. On board, there is a full set of gaming features: Variable Refresh Rate (VRR), Auto Low Latency Mode (ALLM), as well as a flawlessly implemented HGiG standard that allows you to enjoy HDR exactly as the creators intended. All of this is complemented by Game Bar – an intuitive command centre where you can check and adjust the most important settings in seconds.

Particular attention should also be paid to Game Motion Plus, Samsung's proprietary motion smoothing technology. It can add extra fluidity to animations, which can be a lifesaver in games running at 60 frames per second, where stability doesn't always hold up. Indeed, support for Dolby Vision in games is lacking, 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.
