Samsung Neo QLED QN95D vs Philips OLED820

Samsung QN95D handles HDR exceptionally well, achieving peak brightness around 2000 nits. In tested movie scenes where the screen is fully illuminated, the TV delivers intense and realistic HDR content reproduction, significantly enhancing the quality of visual experiences. However, similar to the contrast, the dimming algorithm can sometimes exhibit limitations. Despite a significant number of Mini LED zones, the TV won’t amaze users with incredible lighting. For example, in scenes from "Life of Pi," where a bright moon appears against a dark background, and in segments of "Sicario 2," featuring intense lighting effects on a dark backdrop, the TV shows very poor performance. During such moments, the TV attempts to reduce the halo effect by dimming the image to a level reminiscent of SDR quality. This results in deep and uniform blacks, but at the cost of losing some details in bright areas. It’s a compromise aimed at maintaining the best possible black quality, although it does make the image lose some of its dynamism. Despite some flaws in the local dimming algorithm's performance, this TV deserves praise for its wide coverage of the DCI-P3 colour gamut. This is made possible by the use of a quantum dot coating, also known as QLED technology, which allows for vibrant and rich colours.

When it comes to HDR quality, the Philips OLED820 uses the same class of WOLED panel found in its biggest rivals – the LG C5 and the Samsung S90F. This means we can expect really solid results. This year, mid-range OLED panels can exceed the threshold of a thousand nits, and the tested model reaches around 1300 nits in some films. This is an outstanding result, allowing the director's vision to be conveyed with incredible precision, as this is the brightness range in which modern productions are mastered. Of course, there are situations where even the OLED820 has to compromise. Full-screen scenes flooded with white, like those in the film The Meg, can drop brightness to 400–500 nits, which clearly diminishes the effect. This is a characteristic of OLED technology that has not yet been fully eliminated. Despite this limitation, it's hard not to appreciate the HDR in this model – high luminance and a wide coverage of the DCI-P3 colour palette at 99% make the image look simply fantastic.

In the category of factory colour reproduction, the Samsung QN95D television has been tested in Filmmaker mode, which offers the best settings from the manufacturer. However, it is not entirely free of flaws. For HD content, there is a significant colour discrepancy, particularly in the white balance, where the red colour clearly dominates the graph. The situation improves with 4K HDR content, but there are still significant drops in blue colour reproduction. These effects can be observed in a scene from the film "Star Wars," where the main character is rendered in overly warm tones.

In terms of contrast, the gamma graph shows a large initial spike, indicating that the television effectively highlights the brighter parts of the image. However, at the end of the graph, we notice a significant drop, which may mean that details may be lost in darker tones. This shape of the gamma curve can affect how users perceive dark scenes, where some details may become too blurred or too dark, causing the image to lose clarity. It's also worth noting the curve corresponding to brightness (EOTF), which is quite correct, except for the initial drop.

Although the Samsung QN95D boasts impressive specifications and advanced technologies to earn the title of one of the best televisions on the market, it requires some improvements in colour reproduction and contrast to fully realise its potential.

The colour reproduction in the factory settings really surprised us, and in a positive way. The Philips OLED820, switched to Filmmaker mode, immediately showed that it was quite well tuned in terms of colour. The white balance was relatively accurate, although there was a slight deficiency in the blue hue, which sometimes gave the image a slightly yellowish tint. However, this is not a drawback that particularly interferes with everyday viewing. A bigger problem arose with the brightness characteristics. The gamma chart clearly deviated from the ideal, as the line was below the expected values, causing the image to be excessively brightened, and the colours looked as if they were covered with a light milky filter. This effect was also noticeable in tests using the Colour Checker pattern, where more pronounced errors appeared.

After calibration, the picture on the Samsung QN95D television achieves truly impressive results. The white balance is perfectly balanced, and error readings rarely exceed a value of 2, which means that colours are displayed very accurately. Most samples from the Color Checker test fall within an acceptable error range, confirming that the television reproduces colours excellently. The contrast has also improved significantly, and the gamma curve is more stable, leading to better visibility of details in dark and bright scenes. However, it is worth noting the EOTF (Electro-Optical Transfer Function) curve, which shows some discrepancies in film tests. Although the television performs well in most scenes, in more extreme cases, details in black can still be lost - this is due to an aggressive dimming algorithm.

Nevertheless, these minor imperfections do not diminish the overall picture quality. After calibration, the Samsung QN95D delights with its visual quality, offering an exceptional experience that will certainly please anyone looking for a top-of-the-line television.

After calibration, both the Filmmaker mode and the gaming mode improved quite a bit. A slight adjustment of the white balance and enhancement of the brightness characteristics yielded excellent results with SDR content – the image looked nearly perfect, natural, and very close to the reference. For HDR material, the situation was similar; the colours looked fantastic, and it was hard to find fault with anything. However, we did notice a certain characteristic, which we had already pointed out when comparing scenes from the film Billy Lynn. The analysis of the EOTF curve showed that the TV has a slight tendency to dim details in the blacks, meaning that the darkest parts are not always displayed exactly as the director intended. Nevertheless, the effect after calibration is superb, and the OLED820 is emerging as one of the more interesting screens in its class. A little bit of fine-tuning is all that’s needed, and there’s really nothing to worry about.

The Samsung QN95D television handles tonal transitions well, even in lower-quality materials, thanks to the noise reduction feature, which acts like a gentle gradient. This feature is incredibly effective, smoothly rendering the image and eliminating unwanted noise while significantly improving the quality of the displayed content. However, as is often the case, excessive effectiveness can lead to unintended side effects. In some materials, this feature can also blur elements that should remain sharp, such as film grain.

Despite this, the television performs well in terms of image scaling, eliminating larger jaggedness in the picture. In a scene where branches are visible, they are not overly artificially sharpened, which allows for a natural appearance, and the model does not have an artificial outline. Overall, this means that even in more challenging conditions, the film material presents itself satisfactorily on the Samsung QN95D. The only downside when watching HD/SD content (like regular terrestrial television) is that we have a slightly cropped image - this is caused by the so-called overscan, which cannot be turned off.

Fortunately, the earlier effects of the mentioned posterisation can be quite effectively mitigated. The "distortion reduction" feature set to medium handles unwanted colour banding well, improving the smoothness of tonal transitions. It does sometimes work a bit too aggressively and smooths out some details – such as the minor imperfections of the actors’ skin – but despite that, it can be considered worth using without major compromises. The upscaling in the OLED820 also performs well. The test image with the model is exceptionally soft, sometimes perhaps too much, although this can be remedied with a slight increase in sharpness in the picture menu – that's a matter of individual preference. The absence of overscan issues with very low-resolution content is also commendable, allowing us to not worry about the image being unnecessarily cropped.

The panel in Samsung QN95 performs very well in terms of motion blur and fluidity. With a refresh rate of 120 Hz and features that reduce blur and jitter, users can adjust the picture settings to their personal preferences, whether for watching films or dynamic sports broadcasts. Users have the ability to customise the motion smoothness on a 10-point scale – from a more frame-like appearance, reminiscent of traditional film, to a smooth, almost theatrical effect that works especially well in sports broadcasts.

Motion fluidity is an area where OLEDs always shine, and the Philips OLED820 confirms this rule. The panel itself offers a refresh rate of 144 Hz, which will mainly benefit PC gamers, but even with standard TV sources or consoles, where it operates at 120 Hz, motion is fast, sharp, and simultaneously smooth, without any signs of smearing. This is thanks to the remarkable response time between pixels, which ensures the image maintains clarity in every dynamic scene. The manufacturer has also added their own smoothness enhancer called "Motion Style." In the menu, we find two sliders – the first, responsible for smoothness, allows for the adjustment of the number of artificially added frames in films. This way, we can choose a raw, cinematic character with clearly visible film frames or a more theatrical image with smooth motion. The second slider is for motion blur reduction, particularly useful in sports broadcasts. Here, we definitely recommend setting it to the maximum value, as the effect is truly excellent.

Samsung QN95D offers a fair bit of features that gamers will appreciate. First and foremost, the television supports Variable Refresh Rate (VRR), which allows for smoother gameplay by eliminating screen tearing issues, especially during dynamic scenes. There's also the Auto Low Latency Mode (ALLM), which automatically switches the TV to low latency mode when it detects a connected console or computer, providing more responsive control.

Additionally, the QN95D Samsung has a gaming mode that reduces input lag to a very low level, which is crucial in games where reflexes play an important role. With a high refresh rate of 120 Hz, the image is exceptionally smooth, significantly impacting the experience of dynamic action games and sports productions. The television also supports G-Sync and FreeSync technologies, which further enhance gameplay smoothness and improve user comfort. An interesting addition is the 'Game Bar' – a special menu that provides quick access to all game-related settings, allowing easy adjustment of the image and parameters to the user's preferences without the need to pause the gameplay.

Although the Samsung QN95D does not support Dolby Vision – which is quite obvious for Samsung TVs – it does offer the HGiG feature, which ensures appropriate image quality in HDR games, in line with the creators' vision.

The Philips OLED820 is one of the most comprehensive TVs for gamers. Onboard, we find practically everything one could expect: two HDMI 2.1 ports with full bandwidth of 48 Gbps (shame there aren't four), Variable Refresh Rate (VRR), Auto Low Latency Mode (ALLM), support for Dolby Vision in games, and a good implementation of the HGiG mode. The TV also handles lower resolutions at 120 Hz without issue, so you can count on great flexibility when choosing different picture modes on your console. Philips also adds a Game Bar – a panel that allows you to change picture modes, add a crosshair, or preview parameters. Although it looks a bit clunky and is less refined than its competitors, it gets the job done. In practice, therefore, the OLED820, in addition to a full set of four HDMI 2.1 connections, offers almost everything a gamer could need.
