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, allowing for a very realistic image. Of course, none of them surpasses the magical thousand, yet the combination of such results and unlimited contrast and black effectively boosts the outcome optically. The last of the scenes, featuring a full-screen burst of sunlight, is actually less bright than the others, although it still represents a commendable level. It is also worth mentioning the excellent coverage of the DCI-P3 colour palette, which will allow for achieving extremely vivid colours.

Samsung QN95D handles HDR exceptionally well, achieving a peak brightness of around 2000 nits. In the tested movie scenes, where the screen is fully lit, the television provides intense and realistic representation of HDR content, significantly enhancing the visual experience. Nevertheless, similar to contrast, the dimming algorithm may sometimes show limitations. Despite the considerable number of Mini LED zones, the television does not surprise the user with incredible brightness. For instance, in scenes from the film "Life of Pi," where a bright moon appears against a dark background, and in excerpts from "Sicario 2," where a strong light effect occurs on a dark background, the television displays very poor results. At such moments, the television attempts to reduce the halo effect by darkening the image to a level reminiscent of SDR quality. As a result, blacks appear deep and uniform, but this comes at the cost of losing some detail in bright areas. It is a compromise aimed at maintaining the best possible quality of black, although it simultaneously causes the image to lose a bit of its dynamism. Despite certain flaws in the operation of the local dimming algorithm, this television 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". It was this mode that we used during all tests. This mode proved to be quite good in terms of colour reproduction; however, other shortcomings effectively detracted from the enjoyment of viewing. Starting with the most basic aspect, the white balance, it was easy to notice that it was marked by a dominance of red, which overall changed the characteristics of the image. We could thus see a strong yellowing of the whites and a shift of all colours towards warmer shades. The gamma, which is a curve just as important, if not more so, was quite significantly lowered, resulting in a considerable drop in contrast, except at the beginning of the graph, where the television insidiously lost details. That’s all regarding SDR materials. Taking a closer look at films with a wide dynamic range, we can observe exactly the same phenomenon of yellowing of the white balance as in films with a standard colour palette. The EOTF curve, which replaces our gamma curve, is practically perfect and cannot be faulted.

In the category of factory colour reproduction, the television Samsung QN95D was tested in Filmmaker mode, which offers the best settings from the manufacturer. Nevertheless, it is not entirely free from flaws. In the case of HD content, there is a noticeable colour deviation, particularly in white balance, where the red colour clearly dominates the graph. The situation improves with 4K HDR content; however, there are still significant drops in blue colour reproduction. These effects can be observed in a scene from the film "Star Wars," where the protagonist is depicted in overly warm tones.

As for contrast, we can observe an initial large jump on the gamma graph, indicating that the television effectively highlights the brighter parts of the image. However, at the end of the graph, we notice a distinct drop, which may mean that in darker tones, details can be lost. Such a shape of the gamma curve can affect the way users perceive dark scenes, where some details may become too blurred or too dark, causing the image to lose clarity. It is also worth noting the curve responsible for brightness (EOTF), which is quite correct, except for the initial drop.

Although Samsung QN95D boasts impressive parameters and advanced technologies to deserve the title of one of the best televisions on the market, it requires certain adjustments in colour reproduction and contrast to fully utilise its potential.

As we mentioned earlier, LG televisions are equipped with advanced tools for carrying out the calibration process. We therefore used them to model the image in the way that the director intended. And without modesty, we must admit that we achieved this phenomenally. Both SDR and HDR materials present a level that clearly indicates that this is how a film should look. It is worth looking at the colour errors on the "ColorChecker" palette here, where practically none of them exceeds "1", apart from two samples.

After calibration, the picture on the Samsung QN95D television achieves truly impressive results. The white balance is perfectly aligned, and error readings rarely exceed 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 hues excellently. The contrast has also improved significantly, and the gamma curve is more stable, resulting in better visibility of details in both 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, details in the blacks can still be lost in more extreme cases – this is due to an aggressive dimming algorithm.

Nevertheless, these minor imperfections do not detract from the overall picture quality. After calibration, the Samsung QN95D impresses with its visual quality, offering an exceptional experience that will certainly satisfy anyone looking for a top-tier television.

Once again, we will take a look at the function responsible for smooth gradation, but we will also address the one that aims to improve the quality of lower-quality materials. The default smoothing of tonal transitions, as we have seen, was not the worst, but it can still be improved. The function has a slider, which allows us to adjust its strength. We recommend using the first one, as it yields very good results and does not blur important details.

Image scaling in 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. Admittedly, there are jagged edges on the trees, but this is not a major issue compared to other manufacturers.

The Samsung QN95D television handles tonal transitions even in lower quality materials, thanks to the noise reduction feature employed, which functions like a gentle gradation. This feature is extremely effective, smoothing out the image and eliminating unwanted noise while significantly improving the quality of the displayed material. However, as is often the case, too much effectiveness can lead to unintended side effects. In some materials, this feature may also blur elements that should remain sharp, such as film grain.

Despite this, the television performs well in the context of image scaling, eliminating larger jagged edges. In a scene where branches are visible, they are not excessively artificially sharpened, allowing 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 (such as regular terrestrial television) is the fact that we have a slightly cropped image – this is caused by the so-called overscan, which cannot be turned off.

The maximum refresh rate that we can set on the LG G4 is 144 Hz. Naturally, this is only possible when connecting the television to a very powerful PC. In other cases, we will be operating at a maximum refresh rate of 120 Hz, which is recommended if we primarily want to watch sport or content with a lot of motion dynamics. For those requiring high fluidity of the image, the manufacturer has implemented a multi-step 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 within a range from 0 to 10, with each degree affecting the degree of smoothing, allowing everyone to find their golden mean.

The LG OLED C4 panel features an average response time of less than 1 ms (which directly results from our measurements), allowing for an incredibly clear image that is unattainable for LCD televisions, whose response times can be as high as several milliseconds. This is clearly visible in the pictures from the "UFO Test," showing no trailing blur behind the object.

The panel in Samsung QN95 performs very well in terms of motion blur and smoothness of movement. With a refresh rate of 120 Hz and features for reducing blur and judder, the picture settings can be customised to personal preferences, whether for watching films or for dynamic sports broadcasts. The user has the option to adjust the smoothness of the image on a 10-point scale – from a more frame-like appearance reminiscent of traditional film to a smooth, almost theatrical effect, which works particularly well for sports transmissions.

We can already say that LG C4, like practically every OLED television from the manufacturer, is exceptionally good in terms of compatibility with consoles and PCs. Thanks to the implementation of four full bandwidth HDMI 2.1 ports at 48 Gbps, the manufacturer has included all features that enhance the gaming experience, among which we find simultaneous support for FreeSync and G-Sync technology. With such a tandem, gamers with a graphics card from AMD or Nvidia can confidently opt for C4. However, what should delight the players requiring the highest possible quality the most is the simultaneous implementation of HDR Dolby Vision and HGIG mode. The first is particularly important as it works with extremely low input lag in all settings.

A standard in the Korean manufacturer's televisions is also the implementation of GameBar, allowing for quick adjustments of settings "on the fly" without the need to exit the game. It also enables image adjustments for visually impaired individuals, which is a very nice touch. Another important piece of information is that when VRR technology is enabled, we will not experience a drop in contrast. This is, of course, due to the panel's design and the absence of conventional backlighting. However, it is 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 of the manufacturer's OLEDs equipped with high refresh rate panels and HDMI 2.1 ports, creates a harmonious whole with consoles. In practice, it is a complete television, and if we expect the highest possible performance in gaming, C4 will be an ideal choice.

Samsung QN95D offers quite a few features that gamers will appreciate. First and foremost, the television supports variable refresh rate (VRR), which allows for smoother gameplay, eliminating issues with tearing, especially during dynamic scenes. We also find the auto low latency mode (ALLM) feature, which automatically switches the television to low latency mode when it detects a connected console or computer, ensuring more responsive controls.

Furthermore, the QN95D Samsung has a game 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 picture is exceptionally smooth, significantly enhancing the experience of fast-paced 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 adjustments of picture and parameters to suit user preferences without the need to interrupt gameplay.

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