The Samsung QN900D stands out as the pinnacle of the 2024 lineup, featuring a VA panel with an impressive number of dimming zones—1344 in the 65-inch version alone. Larger sizes include even more zones, enhancing the TV’s excellent contrast performance. This level of precision allows for deep blacks and bright highlights, enabling the QN900D to hold its own against OLED displays in terms of contrast, an achievement that places it among the best LED TVs on the market.
Testing the TV with film scenes, such as those from Oblivion, reveals its outstanding contrast capabilities, with values approaching infinity, giving visuals incredible depth and vividness. This helps deliver a cinematic experience with rich shadow detail and high brightness where needed. However, the QN900D is not immune to the inherent limitations of LCD technology. Notably, in scenes with very fine details, such as star-filled skies or candle-lit rooms (e.g., scenes from The Revenant), some haloing or blooming may appear around bright objects against dark backgrounds. Additionally, intense local dimming can lead to noticeable screen darkening, especially in high-contrast scenes like those from Gravity.

Under synthetic testing conditions, the television showcased its impressive light output, achieving 1400 nits, which is undeniably remarkable. This capability was also evident in the opening scene of Life of Pi, featuring a vibrant sunrise. However, due to certain dimming algorithm issues, some drawbacks are noticeable. For instance, in test scenes from Sicario 2 and the second scene of Life of Pi, the brightness levels dropped to an average of 500-600 nits. While this performance isn't poor by Mini LED standards, expectations were higher given the premium price of the TV. Nonetheless, the set should be commended for covering a wide colour gamut of DCI-P3 at around 96%. Although some technologies offer higher coverage, this is still a commendable result.
Scene from the movie “Pan” (about 2800 nits)
Scene from the movie “Billy Lynn” (about 1100 nits)
In tests featuring demanding films mastered at very high brightness levels (around 2800 nits), the Samsung QN900D showcased its excellent adaptability to extreme lighting conditions. In the film Pan, the TV managed light separation superbly, ensuring the sun did not merge into the rest of the image, while the play of shadows appeared subtle and natural, resulting in an impressive visual display. In Billy Lynn's Long Halftime Walk, the QN900D excelled at presenting bright scenes, capturing the characters in the foreground accurately and without visible distortions. The background effects, such as fireworks, conveyed various shades of fire. However, a contrast issue was noticeable, highlighting the previously mentioned challenge with the dimming algorithm. Despite this, the QN900D performed admirably, adapting well to challenging film scenes even with the dynamic tone mapping feature disabled, which we suggest keeping off as it artificially enhances the image.
HDR luminance chart:
We tested the television's performance with the same scene across various HDR formats to assess how it handles different metadata types. Using static HDR10, the results were underwhelming – in lower models of Samsung's 4K series, such as the QN95 or QN92, the effect was decent, but here it felt average. The image sometimes appeared merged, lacking distinct details in areas like the snowy clearing, which diminished the scene’s depth and realism. Dynamic HDR10+, however, significantly elevated picture quality, showcasing detailed visuals. The distant forest stood out clearly against the rest of the scenery, and the snow gained texture, lending the image a more lifelike and engaging appearance. The Samsung QN900D excelled in dynamic scenes, providing impressive lighting effects and well-defined details where HDR10 struggled. However, the lack of support for Dolby Vision, which is more widely used and popular, particularly on services such as Netflix, is a notable drawback.

Dynamic: HDR10+
Factory color reproduction
6.6/10
The television includes a Filmmaker mode, intended to present films in the most authentic way possible, but it does come with some issues. For HD content, the white balance shows a dominance of red and blue, giving the image a pinkish hue. Conversely, for 4K HDR content, the levels of blue and red drop, resulting in a warming effect that shifts colours towards yellow tones. Colour Checker tests confirm this tendency, with colour samples visibly drifting in this direction.
In terms of brightness and contrast, the gamma is notably disrupted. The main issue is a marked spike at the start of the graph, indicating that dark details are excessively brightened, which reduces depth in the darkest parts of the image due to zone dimming. For 4K HDR content, the EOTF curve performs reasonably well but falls below the reference level, affecting the overall image dynamics.
Color reproduction after calibration
8/10
After calibration, the Filmmaker mode truly lives up to its name. The white balance for both HD and 4K HDR content has been significantly improved, resulting in more natural and consistent colours. The pink hues in HD content and the yellow tint in 4K HDR have been effectively eliminated, enhancing the realism of the image. As a result, the television now offers much better colour reproduction, positively impacting the overall viewing experience.
However, when it comes to brightness, the gamma curve now reveals a noticeable drop at the beginning, making the darkest details more difficult to discern. The EOTF curve for 4K HDR content remains largely unchanged and still falls short of the reference level, meaning the television continues to struggle with maintaining appropriate brightness. This issue is tied to the aggressive dimming algorithm, which affects overall brightness and black levels.
Despite the limitations associated with local dimming, the television has seen an improvement in colour reproduction quality. The Color Checker test results confirm that the colour samples are now much closer to the standards, resulting in a more natural and visually pleasing image.
Smoothness of tonal transitions
8/10
The Samsung QN900D television handles tonal transitions smoothly, earning a score of 8/10. Colour gradation is generally good, though not flawless – in darker scenes, some imperfections may be noticeable to more discerning viewers. Despite these minor flaws, the overall effect should satisfy most users, providing natural and fluid transitions.
Image scaling and smoothness of tonal transitions
7/10
Smooth transition function
Image without overscan on the SD signal
The smoothness of tonal transitions in lower-quality materials looks great – the Noise Reduction function effectively smooths tonal transitions while eliminating film grain. Although removing grain is not always desired, the final effect looks very aesthetic, especially for those who prefer a cleaner image.
As for upscaling, the Samsung QN900D demonstrates the enormous capabilities of the new AI technology processor. Photos and materials in lower resolution are upscaled while retaining many details – for example, a photo with a model looks great, devoid of unnecessary jagged edges, and the branches in the background are not overly aliased.

Blur (native resolution, maximum refresh rate):
Smużenie (2160p 240Hz):
With blur, the Samsung QN900D performs at an acceptable level, though not exceptional. Despite such a fast panel, a slight glow can sometimes be noticed behind objects, particularly on darker backgrounds, as seen in our UFO test. This is due to the panel's average response time. The rating could be considerably higher were it not for this limitation. In this regard, OLED TVs still hold the advantage, offering near-instantaneous pixel response times. That said, motion smoothness on the QN900D is still very good, and the blur should not significantly impact the overall viewing experience. As for the BFI (Black Frame Insertion) feature it remains a bit of a curiosity, as it only supports 60Hz, and the flickering effect it introduces may cause discomfort for some users.
