Samsung S90D / S94D 48" (WRGB OLED) vs Philips OLED769

In the tested movie scenes, the Samsung S90D delivers impressive brightness levels, exceeding 800 nits in the first four shots—a very strong result. In the final shot, featuring a full-screen burst of sunlight, brightness drops to approximately 400 nits, which is still acceptable. Notably, larger versions of this model exceed 1,000 nits, offering even more impressive performance. Additionally, the colour space coverage of DCI-P3 at 97% ensures rich and realistic colour reproduction, greatly enhancing image quality. For those considering the size of the S90D, it is worth noting that larger variants with QD-OLED panels deliver even better HDR performance, making them an excellent choice for those seeking optimal visual fidelity.

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.

The Samsung S90D television has been tested in Filmmaker mode, which offers good colour reproduction, although with some imperfections that may be noticeable to more demanding users. This mode may seem too warm, and users who switched from Standard mode may experience a slight shock. It is worth noting that this state of affairs is caused by poor settings, for example, in the white balance, rather than the Filmmaker mode itself. In both SDR and HDR content, the device shows drops in blue colour, causing colours to become warmer than they should be. In practice, this means that some shades, such as sky blue or skin tones, may appear less natural and more tinged with pink or yellow. The Colour Checker test confirms these deviations, showing shifts towards warmer tones. In SDR content, the gamma graph indicates slight fluctuations, causing the image to be minimally darker, especially in shadows. This may affect less distinct details in darker scenes. Meanwhile, in 4K HDR materials, the EOTF curve is above the recommended line, which leads to some parts of the image being displayed too brightly, potentially causing clipping in the brightest areas. Overall, the Samsung S90D presents a solid picture straight out of the box, but for the best results, especially with more demanding content, additional calibration is recommended.

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.

After calibration, the S90D TV delivers an even more impressive performance in movie mode. The white balance for both HD and 4K HDR content is now nearly perfect. While there are still some minor imperfections, they are so subtle that they don't significantly impact the overall image quality. The colours are more balanced, offering a natural depiction of details, especially in scenes that require precise colour accuracy.

It's important to note that the 48-inch model features a WOLED panel, which differs from the larger sizes. This results in a smaller coverage of the wide colour gamut, meaning it doesn't offer the same rich colours as the 65-inch version, which is equipped with a QD-OLED panel.

Contrast has also seen a substantial improvement. The gamma curve after calibration is much closer to the ideal line, achieving a better balance between bright and dark areas of the image. The EOTF curve, which previously showed issues with overly bright scenes, now performs much better, retaining more detail in the bright sections of the image, especially in HDR content.

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 S90D TV excels in smoothing tonal transitions, offering natural and seamless colour shifts. Thanks to its advanced technology, it ensures a smoother visual experience overall. The noise reduction feature can further enhance tonal transitions, making it beneficial in certain situations. However, it’s important to note that enabling noise reduction may also smooth out the film grain, which can detract from the cinematic feel. For this reason, it's advisable to use the feature sparingly, preserving the natural grain that adds depth and authenticity to the content.

Samsung continues to impress with its scaling capabilities, with the S90D effectively processing lower-resolution content. The image is sharp and clear, maintaining proper outlines and presenting details accurately. For example, tree branches are rendered well, with no noticeable jagged edges that would compromise image quality. Thanks to the effective scaling, even lower-resolution materials are displayed attractively, making it a great choice for users who enjoy content from diverse sources, such as regular antenna or cable television.

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 S90D TV features a 120 Hz panel, which can be "overclocked" to 144 Hz with the appropriate PC setup, delivering exceptional motion fluidity.
