Samsung QD-OLED S90D / S94D vs Samsung Neo QLED QN95D

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.

The Samsung QN95D excels in HDR performance, achieving an impressive peak brightness of approximately 2000 nits. In tested movie scenes with fully lit screens, the television delivers an intense and realistic representation of HDR content, significantly enhancing the viewing experience. However, as with its handling of contrast, the dimming algorithm occasionally reveals limitations.

Despite the large number of Mini LED zones, the television doesn’t consistently provide extraordinary brightness. For instance, in scenes from "Life of Pi," featuring a bright moon against a dark background, and excerpts from "Sicario 2," showcasing intense light effects on dark backdrops, the QN95D underperforms. In such instances, the television mitigates halo effects by dimming the image to a level closer to SDR quality. While this ensures deep and uniform blacks, it comes at the cost of losing some detail in bright areas. This compromise is intended to preserve black quality but can detract from the image’s dynamism.

Despite these occasional shortcomings in the local dimming algorithm, the QN95D deserves commendation for its wide coverage of the DCI-P3 colour gamut. Thanks to the quantum dot coating, also known as QLED technology, the television produces vibrant and richly saturated colours, adding to its appeal for HDR content.

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 Samsung QN95D was evaluated for factory colour reproduction in Filmmaker mode, which provides the manufacturer’s optimised settings. While this mode delivers good performance, it is not without shortcomings. For HD content, notable colour deviations were observed, particularly in white balance, where a red tint dominated the chart. Improvements were noted with 4K HDR content; however, significant deficiencies in blue colour reproduction persist. This is evident in scenes such as those from Star Wars, where the main character appears in tones that are warmer than intended.

Regarding contrast, the gamma chart reveals an initial steep rise, demonstrating the television’s capability to emphasise brighter image areas effectively. However, the chart also shows a clear dip at the lower end, suggesting a potential loss of detail in darker tones. This gamma curve shape could impact the clarity of dark scenes, where details may appear overly blurred or obscured. Additionally, the brightness curve (EOTF) was mostly accurate, aside from an initial drop.

Despite these minor issues, the QN95D boasts impressive features and cutting-edge technology that solidify its position as one of the top televisions on the market. However, refinements in colour accuracy and contrast are needed to maximise its potential fully.

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 calibration, the Samsung QN95D delivers truly impressive results. The white balance is perfectly aligned, with error readings rarely exceeding 2, indicating faithful colour reproduction. Most samples from the Colour Checker test fall well within an acceptable error range, confirming the television's excellent performance in accurately displaying colours. Contrast has also improved significantly, and the gamma curve has become more stable, ensuring better visibility of details in both dark and bright scenes.

However, the EOTF (Electro-Optical Transfer Function) curve still shows a slight divergence in film tests. While the television performs well in most scenarios, some details in black may still be lost in extreme cases due to the aggressive dimming algorithm.

Despite these minor imperfections, the overall image quality remains outstanding. After calibration, the Samsung QN95D impresses with its visual performance, offering an exceptional experience that will satisfy anyone seeking a top-tier television.

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.
