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

The LG G4 excels in delivering an incredibly vivid HDR experience, positioning it as one of the best models in its class. Equipped with second-generation Micro Lens Array (MLA) technology, it achieves a remarkable peak brightness of 1474 nits in real-world scenes. While it may not match Mini LED-backlit LCD TVs in full-screen white scenes, the overall performance is outstanding. The fine details in HDR content shine brightly, a distinct advantage of OLED technology over non-OLED displays. With this impressive brightness and wide DCI-P3 colour gamut coverage, HDR content is brought to life with unmatched engagement and immersion.

Samsung S95F in the 83-inch variant with Tandem OLED panel also enchants with 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 television easily achieves brightness values exceeding 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 designs.

The limitations of organic panels reveal themselves only in full-screen scenes completely filled with white. In the case of this model, for example, in the last shot from the movie The Meg, brightness drops to around 1000 nits – a bit lower than in the smaller QD-OLED variants, where the result remained around 1400 nits. Nevertheless, we are still talking about a remarkable result, unprecedented in OLED televisions of this size. Color reproduction is equally impressive. The new Tandem OLED panel essentially catches up with QD-OLED televisions, offering excellent coverage of a wide color gamut. The results are slightly weaker than those of QD-OLED, but in practice, they still provide an image whose intensity and naturalness of colors are hard to compare with any other television.

Before calibration, the "Filmmaker" mode on the TV had a noticeable red and green colour dominance, resulting in a warm-yellow hue across both SDR and HDR content. This warm tone, typical of modes like "Cinema" and "Filmmaker," led to a yellowish cast that was evident when switching from the "Standard" mode.

Looking at the brightness characteristics, the Gamma chart showed decent performance for mid-tones and bright whites, but it struggled with the darkest details, which tended to merge into a black blob. HDR content, as represented by the EOTF curve chart, displayed a drop in contrast due to excessive brightness, which overshadowed fine details and negatively affected the overall image quality. Additionally, the "ColourChecker" chart revealed that colours were under-saturated, contributing to a less accurate and vibrant visual experience.

This provided a good foundation to build on, but calibration was needed to bring out the full potential of the "Filmmaker" mode and address these issues.

The best picture mode straight out of the box is undoubtedly Filmmaker Mode. This mode has been present in Samsung TVs for several years, and its intention is to reproduce the image as faithfully as possible to the creators' vision. In SDR content, it works reasonably well, although not without flaws. The picture is slightly dimmed, and the white balance tends to shift towards red and blue, resulting in a slight pinkish hue on the screen. Average color errors hover around ΔE values of 3–4, which is on the edge of what most people can perceive with the naked eye.

The limitations are much more apparent with HDR content. Here, a slight excess of blue in the white balance is not as big of a problem – the real issue becomes how the TV manages brightness. In many scenes, the picture looked as if it had been overexposed, and details in the dark could completely disappear. The final effect did not represent what the equipment of this class is capable of and led to significant color errors. It’s hard to understand why such a factory characteristic was chosen, as the HDR reception in this version definitely was not what it should be.

The manufacturer has been offering extensive support for the calibration process in its LG televisions for many years. Therefore, we used 2- and 20-point grayscale adjustments along with an advanced CMS (Colour Management System) to optimise the display. As shown, the calibration procedure greatly improved each parameter. The results included studio-quality colour reproduction, enhanced detail in dark areas, corrected brightness characteristics, and accurate colour saturation. This led to a near-perfect match with the reference image—the one the film director saw on the preview monitor. It’s also worth mentioning that LG G4 televisions are unique in offering even deeper image adjustments through 3D LUT matrices, a feature primarily suited for post-production or graphics studios.

After calibration, the S95F shows what it is truly capable of. The white balance was corrected, and minor inaccuracies were adjusted, making the image in SDR content look almost exemplary. Color differences have dropped below the level that the human eye can detect – looking at the screen, one simply feels a full sense of naturalness and color coherence.

In HDR, the improvement is equally noticeable. The television handles brightness much better, eliminating the "blowing out" effect of the entire frame. Bright scenes are more controlled, and blacks retain more detail, although sometimes there may still be slight brightening of the image as a whole. Nevertheless, after calibration, the S95F delivers an image that can confidently be called one of the best on the market – regardless of whether we are watching films in SDR or spectacular productions in HDR.

The LG G4 does not perform well with materials rich in tonal transitions, leading to a pronounced posterization effect. However, the manufacturer has included a smoothing system called "Gentle Gradation," with three levels: Low, Medium, and High. These settings are effective at smoothing bright colours, though less so for darker tones. It is recommended to use the Low setting, as the higher levels can distort the director's intentions by removing film grain.

When it comes to upscaling lower-quality material, the television's performance is quite good, delivering a sharp and clear image. However, attention should be paid to the jagged edges of fine details and the occasional halo effect around figures. This occurs due to the sharpening imposed by the LG G4, even when the lowest setting is selected (0). This is a noticeable change from the LG G3, which did not apply such strong sharpening, even at setting 0.

The Samsung S95F model features a noise reduction function aimed at improving the fluidity of tonal transitions. Its performance is hard 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 because of it, reminiscent of a painted effect. The problem is that along with the noise, the natural film grain, which gives the image a cinematic quality, also disappears. Fortunately, the function does not blur essential details, so its use is more a matter of taste. 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 video looks quite good, although some 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 can be seen that those models can extract a bit more from the image. However, it's worth remembering one inconvenience: with older films and photos, there is an overscan issue that causes a slight cropping of the left edge of the image.

The LG G4 offers a maximum refresh rate of 144 Hz, achievable when connected to a powerful PC. For most users, however, the TV operates at a maximum of 120 Hz, ideal for watching sports or other content with fast motion. To improve image fluidity, the television includes the "TrueMotion" motion smoothing system, which features two separate sliders: De-Blur (for the sharpness of moving images) and De-Judder (for judder reduction). These sliders allow users to adjust the level of smoothing between 0 and 10, ensuring everyone can find the ideal setting.

With a response time of 0.78 ms, the LG G4 delivers exceptionally clear images, outperforming LCD televisions, which can have much slower response times. This results in no trailing blur behind moving objects, as shown in the "UFO Test." The TV also provides precise control over motion smoothing, which is especially beneficial during fast-paced video game sequences. Thanks to OLED technology, the G4 eliminates ghosting, ensuring a crisp and clear image even during the most dynamic sports or action scenes.

In the case of the 83-inch S95F with a Tandem OLED panel, the motion smoothness 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 sports look remarkable. Additionally, the manufacturer 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 TV supports all the features encompassed by the HDMI 2.1 standard, making it a gaming powerhouse. During testing, every feature activated seamlessly, ensuring a smooth experience for both console gamers and PC users. Notably, the HGIG mode (HDR Gaming Interest Group) is implemented correctly, allowing games mastered to brightness levels higher than the TV’s maximum luminance to map tones accurately, preserving the game’s original visual integrity.

A notable highlight is the dedicated GameBar, which can be accessed at any time to quickly check or adjust game settings. More importantly, enabling VRR (Variable Refresh Rate) does not compromise contrast—a common issue in TVs with local dimming or Mini LED backlighting. This is thanks to the OLED panel’s self-emissive pixels, which maintain consistent contrast. However, a slight grey flicker may appear when VRR is enabled, though this is standard across OLEDs.

In summary, the LG G4, like most OLED TVs, is ideal for gaming and online competitions. Its HDMI 2.1 ports offer a full 48 Gbps bandwidth, supporting features such as VRR, ALLM (Auto Low Latency Mode), G-Sync, FreeSync, and HDR Dolby Vision gameplay, ensuring an exceptional gaming experience.

The low trailing and phenomenal motion fluidity, which are the hallmarks of OLED technology, 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 limitations. On board is a complete set of gaming features: variable refresh rate (VRR), automatic low latency mode (ALLM), and a flawlessly implemented HGiG standard, which allows you to enjoy HDR exactly as the creators intended. All of this is complemented by Game Bar – an intuitive control center where you can check and adjust the most important settings in seconds.

Particular attention should also be paid to Game Motion Plus, Samsung's own smoothing technology. It can add extra fluidity to animations, which can be a lifesaver in games running at 60 frames, where stability doesn't always hold up. Indeed, support for Dolby Vision in games is missing, 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 favorites for the title of the best gaming TV on today's market.
