LG OLED G4 vs Philips OLED769

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.

Philips OLED769 performs quite well, particularly in film scenes with small points of light. The television surprises with its brightness, reaching around 800 nits, which is an impressive result. As a result, fine sources of light, such as street lamps at night or stars in the sky, are sharp and full of detail. However, the biggest challenge for this model is the scene with a full-screen burst of sunlight. In such moments, the brightness drops to about 250 nits, which is not very impressive. This is a typical problem for cheaper OLED displays, which struggle to maintain high brightness across the entire screen surface.

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 "Film" mode proved to be the best factory setting in terms of fidelity to the source material, and it is on this that we based our tests. However, like other factory modes, it was not without flaws. Let us examine, therefore, what exactly went wrong in SDR and HDR materials.

In both cases, the white balance was disrupted by the excessive dominance of green and red hues. This phenomenon created a yellowish tint that spread across the entire image, leading to issues such as yellowed whites and unnatural skin tones. These problems were clearly highlighted on the "ColourChecker" palette, where each of the samples was shifted towards warmer tones.

As for contrast and brightness, in the Philips OLED769, we can look at two key graphs: Gamma for HD content and the EOTF curve for 4K HDR content. In the case of the first graph, the gamma value falls below the optimal level of 2.4, resulting in an increase in brightness of light areas of the image. This means that bright elements may be slightly overexposed, losing detail and depth. In contrast, the EOTF curve for 4K HDR content performs really well. The graph shows that the television effectively conveys details in both the brightest and darkest areas of the image, resulting in a realistic and dynamic representation of scenes.

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 professional calibration, Philips OLED769 truly shines in terms of colour accuracy. The television has been completely stripped of any yellow tint in both HD and 4K content. The Colour Checker test confirms that deltaE errors are minimal, occasionally exceeding a value of 2, which means we can speak of almost perfect director's representation.

When it comes to contrast, the situation is equally impressive. With 4K materials, there wasn't much to improve initially, while the gamma chart has been significantly enhanced. This allows dark and light areas of the image to be represented with greater accuracy, resulting in a realistic and dynamic portrayal of scenes.

The calibration has allowed the full potential of this television to be unleashed, both in terms of colours and contrast. Philips OLED769 now offers vivid, natural images of high quality that will delight any user, whether they are watching films or using other multimedia.

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.

When it comes to lower quality materials, the distortion reduction in the Philips OLED769 handles tonal transitions well, especially at the minimum setting. It is worth noting that at this setting, film grain is not blurred, which is a pleasant surprise, as such negative phenomena often occur with other manufacturers. Overall, it 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 television struggles with smoothing tonal transitions and may present more noticeable distortions and noise, reducing picture quality in dynamic scenes.

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

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.

Philips OLED769 features a multi-stage motion smoother called "Motion Style", which will satisfy users who appreciate the ability to customise the fluidity of motion in films. With this function, you can set the image to be more frame-like or smooth, resembling a theatrical effect. This is a great solution for those who want to adapt the displayed content to their visual preferences. Gamers will also not be disappointed, as the television, like most OLEDs, is equipped with a 120Hz panel. This provides exceptional fluidity and dynamism of the image. Unfortunately, Philips OLED769 does not have the BFI (Black Frame Insertion) feature, which could further improve motion fluidity and sharpness. Despite this limitation, the television still offers excellent visual experiences for both cinema lovers and gamers. This is definitely one of its strong points.

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.

Philips OLED769 has been designed with gamers in mind, offering full compatibility with consoles and the highest quality of gameplay. The television received the maximum rating in this category, providing everything that the heart desires. 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 television to low latency mode, while VRR eliminates stuttering and screen tearing, resulting in fluidity and stability in gaming. The Dolby Vision gaming feature is another advantage, although it only works at a frequency of 60 Hz. Most casual gamers will likely not feel the lack of a higher frequency; however, more demanding users may have some reservations. This allows for enjoyment of a dynamic range of tones and realistic images, enhancing the gaming experience. PC gamers will also not be disappointed, as Philips OLED769 offers full compatibility with Nvidia graphics cards, thanks to support for G-Sync. This technology synchronises the refresh rate of the television with the graphics card, eliminating tearing and stuttering, resulting in excellent image fluidity.

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