Samsung QD-OLED S90D / S94D vs Philips OLED769

In the HDR effect category, the Samsung S90D delivers remarkable performance. On the luminance graph for up to 10% of the window, the television surpasses the 1000 nits mark, which is a notable achievement. However, in the film scenes we tested, these values were slightly lower. In scenes with fullscreen sun glare the brightness drops to about 500 nits, but this is still considered a very good result. It is also worth noting that this model stands out due to its very high colour gamut coverage, thanks to the QD-OLED panel, giving it an edge over televisions with WOLED panels, which cannot achieve such a wide spectrum of colours.

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 Samsung 65" S90D with a QD-OLED panel has been tested in Filmmaker Mode, which the manufacturer has used for years to deliver optimal picture settings. In this mode, the TV offers a very good image, but there are some shortcomings worth noting.

In terms of white balance, viewers may notice a red dominance in HD content, which can make skin tones appear unnatural and create a warm overall scene, potentially affecting immersion. This issue becomes more apparent in scenes where subtle colour differences are important. The same effect can be observed in 4K HDR content, though the red shift is less pronounced. This shift can prevent certain details and colours from being fully realised, diminishing the naturalness of the image.

As for contrast, the gamma performance is decent but still has some issues. The gamma values fall short of the reference level of 2.4, resulting in bright areas of the image appearing washed out and dark areas lacking detail. This limitation can make certain scenes feel less dynamic and impact the depth and richness of the picture. However, the EOTF curve for contrast in 4K HDR content performs well, showing the TV's ability to handle differences in brightness. That said, these values still fall slightly below the ideal range, indicating room for further optimisation.

Overall, the Samsung S90D in Filmmaker Mode offers solid colour reproduction, but some adjustments are needed to fully unlock its potential, particularly with different types of content.

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 quality improves more than anticipated after calibrating the S90D television in movie mode. The white balance for HD and 4K HDR content has been fine-tuned to near perfection. While minor imperfections are still noticeable, they are subtle enough not to significantly impact the overall picture quality. Colours have become more cohesive, promoting a natural reproduction of details, particularly in scenes where precise colour representation is essential. It’s important to note that this particular model, in this size, uses a QD-OLED panel, which offers a broader colour gamut compared to other versions of this model equipped with a WOLED panel.

The contrast has also seen a marked improvement. After calibration, the gamma chart is much closer to the expected curve, resulting in a better balance between the bright and dark areas of the image. The EOTF curve, which previously indicated issues with overexposed scenes, now shows significantly better results. This improvement allows for greater preservation of details in the brighter parts of the image, particularly in HDR content.

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 television excels at smoothing tonal transitions, allowing colours to blend seamlessly, resulting in a natural and fluid image. The built-in noise reduction feature can further enhance these transitions, useful in certain situations. However, it is important to note that activating this option may overly smooth out the desired film grain structure, potentially compromising the authenticity and atmosphere of the image. Therefore, caution is advised when using this feature, to maintain the character and depth of the content.

The S90D model handles lower-resolution materials effectively, as demonstrated in the displayed image. The model's silhouette remains sharp and naturally reproduced, with fine details preserved. Additionally, the branches of the trees are well-defined, free from any visible jagged edges that might otherwise degrade the image quality. Thanks to efficient scaling, even lower-resolution content appears attractive on the screen, which is sure to please users who rely on a variety of content sources, such as standard cable or antenna television.

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 S90D TV, featuring a 120 Hz refresh rate matrix and up to 144 Hz in the appropriate PC configuration, delivers excellent motion fluidity. Samsung highlights a range of sharpness settings on a ten-point scale, allowing users to fine-tune the display to their preferences. In UFO tests, the OLED matrix showcases its strengths by eliminating any blurring. The ultra-fast pixel response ensures dynamic movements are faithfully reproduced.

Similar results can be seen in other sizes of this model with a WOLED matrix, which also offer outstanding image fluidity. Organic technology, in this case, is considered among the best on the market. The S90D image, regardless of the matrix type, is exceptionally sharp and detailed, making this television perfect for dynamic scenes, whether for gaming or sports broadcasts. Additionally, its refresh rate and sharpness capabilities guarantee that every movement is smooth and natural, satisfying even the most discerning users.

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.
