Philips OLED769 vs LG QNED91T6A

Philips OLED769 performs quite well, especially in movie scenes with small light points. The television surprises with its brightness, reaching around 800 nits, which is an impressive result. This means that small light sources, like street lamps at night or stars in the sky, are vivid and full of detail. However, the biggest challenge for this model is the scene with a full-screen sun glare. In such moments, the brightness drops to around 250 nits, which isn’t very impressive. This is a typical issue with cheaper OLED displays, which struggle to maintain high brightness across the entire screen.

As befits a MiniLED television, LG QNED91T easily exceeds the magical barrier of 1000 nits on the luminance chart. In scenes where light played a key role, the effect was truly commendable. For instance, 1000 nits in the first scene of "Life of Pi" is a really impressive value, and the achieved 600 nits in the third and fifth scenes allowed for a true sense of HDR magic. However, problems arise with very small light elements on the screen, such as the moon, street lamps, or lights. Values around 100 nits - to put it bluntly - are disappointing, as these elements are so dark they are barely visible. The television deserves praise for covering 96% of the DCI-P3 colour gamut and 75% of BT.2020. LG QNED91T leaves us with very mixed feelings, mainly due to the very aggressive dimming algorithms which, while effectively eliminating halo effect, do impact the brightness of smaller elements.

The "Film" mode turned out to be the best factory setting in terms of fidelity to the original material, and it was on this setting that we based our tests. However, like other factory modes, it was not without its flaws. Let’s take a closer look at what exactly went wrong in the SDR and HDR materials.

In both cases, the white balance was disturbed by excessive dominance of green and red colours. This phenomenon created a yellowish tint that spilled over 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 shades.

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 is below the optimal level of 2.4, resulting in the bright parts of the image being lightened. This means that bright elements may be somewhat overexposed, losing detail and depth. Meanwhile, the EOTF curve for 4K HDR content performs really well. The graph shows that the television effectively reproduces details in both the brightest and darkest parts of the image, translating to a realistic and dynamic representation of scenes.

All our tests are conducted in the best picture mode on each television. In this case, as usual, it’s the Filmmaker mode. The name of the mode suggests ideal colour reproduction; however, there were noticeable deviations from the correct image. Our unit, in terms of white balance, exhibited a significant drop in blue hues - both in SDR and 4K HDR materials - resulting in a noticeable yellowing of the image, evident in the comparison scenes from a movie with Tom Cruise. As we described earlier, QNED91T has a tendency to brighten the screen. This is confirmed by the gamma, which is quite significantly lower than the reference value of 2.4. Meanwhile, the EOTF curve, which is responsible for brightness in 4K content, showed some issues with the television’s ability to dim the image in the darkest areas, which we could observe in the paragraph describing the quality of the HDR effect. Although the Filmmaker mode is a pretty good "out of the box" mode, it still requires some adjustments.

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

When it comes to contrast, the situation is equally impressive. For 4K materials, there wasn't much to improve from the start, while the gamma graph has been significantly enhanced. As a result, dark and bright parts of the image are represented with greater accuracy, leading to realistic and dynamic scene reproduction.

The calibration has unlocked the full potential of this television, both in terms of colour and contrast. Philips OLED769 now offers vivid, natural images of high quality that will delight any user, whether they're watching movies or using other multimedia.

LG offers advanced calibration tools in its televisions such as 65QNED91T6A, which we took advantage of. When it comes to white balance, we managed to significantly correct it in SDR content. The picture mode in 4K HDR quality posed greater challenges, which, while still not perfect, looks significantly better than before calibration. The errors on the Color Checker palette and the colour palette are much smaller than in the factory settings. In terms of brightness characteristics, gamma for HD content is practically perfect, with a small exception at the end of the graph. However, the biggest issues the television faced were with brightness in 4K HDR content. Analyzing the EOTF characteristics in films, we noticed that the television manipulates brightness quite a bit, which we could observe in previous tests. Brightness is significantly boosted compared to the graph in the static test, and the television brightens certain scenes to the extent that some smaller details lose definition. Unfortunately, this is caused by an average backlight zone management algorithm in this model. Nevertheless, the calibration yields quite good results, especially regarding accurate colour reproduction.

When it comes to lower quality materials, the distortion reduction in the Philips OLED769 does well at smoothing tonal transitions, especially at the minimum setting. It's worth noting that at this setting, film grain isn't blurred, which is a pleasant surprise, as such negative phenomena often occur with other manufacturers. Overall, it's quite a decent solution. However, it should be noted that this setting doesn't 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 image quality in dynamic scenes.

As for digital processing, the Philips OLED769 performs well. The model in the picture isn’t overly jagged, and the branches in the background lack the characteristic artifacts. The television achieves this effect by avoiding artificial sharpening, which may be an advantage for some users. However, others may find this less appealing, as they prefer a more vivid, sharper image rather than a subtle effect. This effect can be mitigated by using a higher setting for the "Sharpness" parameter.

When it comes to tonal transitions in lower quality materials, the television offers a well-known feature from LG TVs - "Smooth Gradation". We can control it at three levels: low, medium, and high. We recommend using the medium option, as it handles tonal transitions well without causing noticeable issues with removing the structure of objects or other artifacts.

On the other hand, when it comes to image scaling (upscaling), LG's Alpha processor performs quite well here. The image appears very smooth, with slight jaggedness in some elements, but this does not significantly affect quality. It looks really good, and the overall effect is very satisfying.

Philips OLED769 features a multi-level motion smoother called "Motion Style," which will please users who value the ability to adjust motion fluidity in films. With this function, the image can be set to appear more stuttery or fluid, reminiscent of a theatrical effect. It's a great solution for those who want to tailor 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 ensures extraordinary fluidity and dynamic imagery. Unfortunately, Philips OLED769 does not have the BFI (Black Frame Insertion) feature, which could further enhance the smoothness and clarity of motion. 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 television has a refresh rate of 120 Hz, which should satisfy most users in terms of motion smoothness. Additionally, QNED91T is equipped with TruMotion technology, which allows for smoother image display in films. With this feature, we can adjust the "De-Judder" and "De-Blur" sliders. The "De-Judder" slider reduces stutter in films, which is particularly useful when playing content with a lower frame rate, while "De-Blur" helps to reduce motion blur in fast scenes, which is important for sports or dynamic shots.

Philips OLED769 has been designed 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 your heart desires. With HDMI 2.1 ports fully supporting ALLM (Auto Low Latency Mode) and VRR (Variable Refresh Rate), the TV ensures smooth and hassle-free gaming. ALLM automatically switches the television to low latency mode, and VRR eliminates stuttering and screen tearing, resulting in smoothness and stability in gameplay. The Dolby Vision feature for gamers is another advantage, although it only works at 60 Hz. Most casual gamers will probably not feel the lack of a higher refresh rate, however, more demanding users may have some reservations. It 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, leading to excellent image smoothness.

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

The LG 65QNED91T6A television is equipped with HDMI 2.1 ports with a full bandwidth of 48 Gb/s, providing full support for all the standards needed for gaming on modern consoles. We can count on variable refresh rate (VRR) support and automatic low latency mode (ALLM). This ensures smooth gameplay without delays.

Thanks to support for all popular HDR standards in gaming, such as HGiG and Dolby Vision, we can fully utilise the potential of the PS5 and XBOX One consoles. The television also easily handles lower resolutions than 4K, so even older consoles look good on it. The Game Bar makes it easier to access gaming-related settings, allowing us to quickly and intuitively adjust picture parameters and features for gamers. Additionally, the QNED91T offers NVIDIA GeForce Now functionality, allowing us to play in the cloud without needing a console. However, it's important to keep in mind that this solution is quite costly and somewhat falls behind the Xbox Game Pass, which is available only on Samsung televisions.

QNED91T LG is a great choice for both less experienced and more advanced gamers looking for a versatile television for gaming.
