LG OLED C4 vs Samsung Neo QLED QN95D

The results of HDR materials are definitely among the better ones. Practically every film significantly exceeds the 700 nits barrier, which allows for a very realistic image. Of course, none of them surpasses the magical thousand, however, the combination of such results along with unlimited contrast and black effectively boosts the visual outcome. The last of the scenes, featuring a fullscreen sun burst, is indeed less bright than the others, although it still represents a respectable level. It's also worth mentioning the excellent coverage of the DCI-P3 colour palette, which will enable the achievement of exceptionally vivid colours.

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.

The best factory mode implemented in the tested television was "Filmmaker". That was the one we used during all tests. This mode, in terms of colour reproduction, turned out to be quite decent, although other flaws effectively detracted from the enjoyment of the viewing experience. Starting with the most basic one, which is white balance, it was easy to notice that this was marked by a dominance of red, which completely altered the characteristics of the picture. We could see a strong yellowing of the whites and a shift of all colours to warmer tones. The gamma, which is a graph as equally important, if not more so, was quite severely reduced, resulting in a significant drop in contrast, except for the start of the graph, where the television insidiously lost details. That’s all regarding SDR materials. Looking closely at films with a wide dynamic range, we can observe exactly the same phenomenon of white balance yellowing as in films with a standard colour palette. The EOTF curve, which replaces the gamma chart for us, is practically perfect and cannot be faulted.

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.

As we mentioned earlier, LG televisions are equipped with advanced tools for carrying out the calibration process. We used them to model the picture in line with what the director envisioned. And without modesty, we must admit that we achieved this phenomenally. Both SDR and HDR materials present a level that clearly indicates this is how a film should look. It's worth taking a look at the colour errors on the "ColorChecker" palette, where practically none of them exceed "1", except for two samples.

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.

Once again, we will take a look at the feature responsible for gentle gradation, but we will also address the one that aims to enhance the quality of lower-quality materials. The default smoothing of tonal transitions, as we could see, was not the worst, but it can be improved further. The function has a slider that allows us to adjust its intensity. We recommend using the former, as it produces very good results and does not blur important details.

Image scaling on LG C4 is quite good, however, it cannot be said to be without flaws. The image is slightly sharper by default, although not in a very noticeable way. While jagged edges of trees can be seen, it is not a major issue when compared to other manufacturers.

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.

The maximum refresh rate we can set on the LG G4 is 144 Hz. Naturally, this is only possible when connecting the TV to a very powerful PC. Otherwise, we will operate at a maximum refresh rate of 120 Hz, which is recommended if we primarily want to watch sports or content with a lot of motion dynamics. For those who require high fluidity of the image, the manufacturer has implemented a multi-level motion smoother called "TrueMotion". It has been divided into two separate sliders that adjust the sharpness of moving images (De-Blur) and judder (De-Judder). Both sliders can be set in the range of 0 to 10, with each degree affecting the level of smoothing, allowing everyone to find their sweet spot.

The panel of the LG OLED C4 features an average response time of less than 1 ms (which directly results from our measurements), enabling the achievement of an extremely clear image, unattainable for LCD TVs, which can have response times of up to several milliseconds. This is clearly evident in the images from the "UFO Test," which show no trailing blur behind the object.

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.

We can now say that LG C4, like practically every OLED television from the manufacturer, is exceptionally good in terms of cooperation with consoles and PCs. Thanks to the implementation of four full-bandwidth HDMI 2.1 ports at 48 Gbps, the manufacturer has embedded all the features that enhance gaming comfort, including simultaneous support for FreeSync and G-Sync technologies. With such a tandem, players with graphics cards from AMD or nVidia can safely choose C4. However, what should please gamers demanding the highest possible quality the most is the simultaneous implementation of HDR Dolby Vision and HGIG mode. The former is particularly important as it operates with extremely low input lag in all settings.

A standard feature in televisions from the Korean manufacturer is also the implementation of GameBar, allowing for quick adjustments of settings "on the fly," without the need to exit the game. It also allows for image adjustments for people with visual impairments, which is an incredibly nice touch. Another important piece of information is that when VRR technology is enabled, we won’t experience a drop in contrast. This is, of course, due to the design of the panel and the absence of conventional backlighting. It is, however, normal for shades of grey to flicker slightly, although this is a characteristic feature of this function regardless of the manufacturer and television.

In summary: LG C4, just like all the manufacturer's OLEDs equipped with high-refresh-rate panels and HDMI 2.1 connections, creates a harmonious whole with consoles. In practice, it is a complete television, and if we expect the highest possible efficiency in gaming, C4 will be an ideal choice.

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.
