LG OLED G4 vs Philips OLED769

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.

The Philips OLED769 performs admirably in film scenes featuring small bright elements. With peak brightness reaching around 800 nits, the TV handles light sources like street lamps or stars with remarkable vividness and detail. However, its limitations become evident during scenes with full-screen brightness, such as sun glare, where brightness drops to approximately 250 nits. This is a common challenge for more affordable OLED models, which often struggle to sustain high brightness across the entire display.

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 "Film" mode on the Philips OLED769 proved to be the most faithful factory setting for preserving the source material, and it was the basis for our tests. However, like other factory presets, it has a few flaws. Let’s break down the key issues observed in SDR and HDR content.

In both formats, the white balance exhibited a noticeable dominance of green and red tones. This led to a yellowish tint across the image, resulting in yellowed whites and slightly unnatural skin tones. This was particularly evident in the "ColourChecker" palette, where colour samples leaned toward warmer shades.

In terms of contrast and brightness, two critical graphs tell the story: the Gamma curve for HD content and the EOTF curve for 4K HDR content. For SDR, the gamma value dips below the ideal 2.4 level, causing lighter parts of the image to appear overly bright. This overexposure reduces detail and depth in bright areas. In contrast, the EOTF curve for HDR content performed admirably, accurately maintaining details in both bright and dark regions. This ensures realistic, dynamic scene reproduction that enhances the overall viewing experience.

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 professional calibration, the Philips OLED769 truly excels in colour accuracy. Any yellow tint previously seen in HD and 4K content is now eliminated. The Colour Checker test shows minimal deltaE errors, occasionally exceeding a value of 2, which indicates a nearly perfect representation of the director's intent.

When it comes to contrast, the results are equally impressive. For 4K materials, there was little room for improvement initially, but the gamma curve has been significantly refined. This leads to a more accurate rendering of dark and bright areas, resulting in a dynamic and realistic viewing experience.

Thanks to the calibration, the full potential of the television has been unlocked. The Philips OLED769 now delivers vibrant, natural, and high-quality images, making it an excellent choice for movie lovers and multimedia users.

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.

When it comes to lower-quality materials, the distortion reduction in the Philips OLED769 does well in smoothing tonal transitions, especially at the minimum setting. It's worth noting that film grain is not blurred, which is a positive surprise, as such negative phenomena often occur with other manufacturers. Overall, this is quite a decent solution. However, it should be pointed out that this setting does not work in HDR mode, where gradation issues are much more pronounced. In HDR mode, the TV struggles with smoothing tonal transitions and may exhibit more noticeable distortions and noise, reducing image quality in dynamic scenes.

As for digital processing, the Philips OLED769 performs well. The model in the photo is not overly jagged, and the branches in the background lack characteristic jagged edges. The TV achieves this effect thanks to the absence of artificial sharpness, which may be an advantage for some users. However, others may find this less attractive as they prefer a more pronounced, sharper image instead of a subtle effect. This effect can be mitigated using a higher setting for the "Sharpness" parameter.

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.

The Philips OLED769 features a multi-stage motion smoother called "Motion Style," which will satisfy users who value the ability to customize motion fluidity in movies. Thanks to this function, the image can be set to be more frame-like or fluid, resembling a theatrical effect. This is a great solution for those who want to match the displayed content to their visual preferences. Gamers will also be pleased, as the TV, like most OLEDs, is equipped with a 120Hz panel. This provides extraordinary fluidity and image dynamics. Unfortunately, the Philips OLED769 lacks BFI (Black Frame Insertion) functionality, which could further improve motion fluidity and sharpness. Despite this limitation, it offers excellent visual experiences for cinema and gaming enthusiasts, one of its main strengths.

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 Philips OLED769 was created with gamers in mind, offering full compatibility with consoles and the highest-quality gameplay. The television received the maximum rating in this category, providing everything one could desire. With HDMI 2.1 ports fully supporting ALLM (Auto Low Latency Mode) and VRR (Variable Refresh Rate), the television ensures smooth and hassle-free gaming. ALLM automatically switches the TV to low latency mode, and VRR eliminates stuttering and screen tearing, resulting in fluidity and stability in gameplay. The Dolby Vision feature for gamers is another advantage, though it only works at 60 Hz. Most casual gamers are unlikely to feel the lack of a higher frequency, but more demanding users may have some reservations. This allows for enjoying a dynamic range of tones and realistic images, enhancing the gaming experience. PC gamers will also not be disappointed, as the Philips OLED769 offers full compatibility with Nvidia graphics cards, thanks to support for G-Sync. This technology synchronizes the TV's refresh rate with the graphics card, eliminating tearing and stuttering, translating to excellent image smoothness.

The Philips OLED769 is a television that perfectly meets the needs of gamers, offering a wide range of advanced features and technologies that significantly improve game quality and user comfort.
