LG OLED G4 vs Philips OLED909

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 OLED909 impresses with the quality of its HDR effect, achieving up to 1500 nits of peak brightness in tested scenes. This is an excellent result, placing this television among the best OLED models on the market. The MLA matrix, also used in models like the Panasonic Z95A and LG G4, plays a key role here, allowing for exceptionally bright and detailed reproduction of dynamic scenes. However, it's worth noting that in the most demanding scene from the movie The Meg, the brightness drops to around 700 nits. This is a typical phenomenon in OLED technology, where intensely bright full-screen images cause a limitation of luminance. Nevertheless, the HDR effect still looks very good, and the television performs better than most competitors under similar conditions. The wide color gamut coverage also deserves praise. The OLED909 offers 95% coverage of DCI-P3, ensuring the television can display vivid and realistic colors.

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.

Like other televisions, the Philips OLED909 has been tested for color reproduction in factory modes. The best mode turned out to be Filmmaker Mode, but despite its name, it is not free of flaws.

The biggest problem is the white balance. Both in HD and 4K HDR content, there is a noticeable dominance of green and red shades, which causes a distinct yellowing of the screen. This effect is particularly visible in test materials, for example in the scene with Tom Cruise in the foreground, where the difference compared to the calibrated image is very clear.

Regarding brightness characteristics, the gamma in HD materials was boosted too much - it was below the reference value of 2.4, which gave the image a "milky" filter and affected the overall clarity. In the case of 4K HDR content, we noticed the opposite phenomenon – there is a clear drop at the beginning of the EOTF curve, indicating problems with reproducing the smallest details in dark scenes. Although the Filmmaker mode offers acceptable quality, noticeable errors in white balance and brightness characteristics show that the television requires additional calibration to fully reveal its potential in color reproduction.

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.

Philips OLED909 offers tools for image calibration, which significantly improves its quality. After calibrating the Filmmaker Mode, the television presents a much more natural color reproduction. The white balance after calibration looks very good. Although we noticed slight deviations in the blue hue in HD content, the errors fall within acceptable limits, and the image looks much better than in factory settings. The brightness characteristics, including gamma and EOTF, have also been distinctly improved. The television no longer has issues with excessive brightening or darkening of the image. Both dark and light details are now rendered correctly, making the image look very good in every scene. After calibration, the Filmmaker mode in the Philips OLED909 offers excellent image quality that will meet the expectations of even the more demanding users. The calibration fully utilizes the potential of this model.

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.

Philips OLED909 offers a distortion reduction feature aimed at smoothing tonal transitions. Unfortunately, the effectiveness of this feature leaves much to be desired. Setting it to "Medium" yields some results, but it comes with the risk of blurring essential details in the image. For this reason, we do not recommend using this option unless you are focused on mitigating visible artifacts at the expense of detail.

When it comes to image scaling, the television presents a very pliable image, which may appeal to viewers who prefer a softer image. Those expecting sharper clarity will also find a solution, as image scaling can be adjusted according to individual preferences in the settings.

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 OLED909 with a 144 Hz panel offers excellent image fluidity, which should satisfy both movie lovers and gamers. Additionally, the television is equipped with a smoothing feature called "Motion Style," which allows precise adjustment of image fluidity to personal preferences. In the settings, we find two sliders: "Fluidity," which regulates the fluidity of motion in movies, and "Motion Blur Reduction," which helps eliminate minor artifacts and distortions in dynamic scenes. This feature works well, making even fast movements on the screen clear and readable.

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 OLED909 is a television that meets practically all the requirements of gamers. Equipped with ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and support for Dolby Vision, it guarantees excellent gaming experiences. Additionally, the television offers very low input lag, ensuring that the response to player movements is instantaneous, which will be especially appreciated by fans of dynamic games.

The television easily supports any resolution at 120 Hz, and even higher refresh rates. The HGiG feature, responsible for the correct display of HDR content in games, works as it should, making the image in game mode balanced and tailored to the guidelines of console manufacturers.

The OLED909 also includes a Game Bar feature that allows for quick previewing and changing of game-related settings. Although the interface of this solution may seem less visually appealing than that of competitors, it serves its purpose well by offering all the most important options in one place.
