LG QNED93A / QNED90A vs Samsung OLED S95H (S99H) (QD-OLED)

Although the number of local dimming zones in the LG QNED93A has not directly translated to noticeably better contrast, it is hard to deny one thing about this model – it is brighter than its predecessor. In synthetic tests, we recorded values around 1400-1500 nits, and more importantly, these results are reflected in real film scenes. In full-screen sequences flooded with white or bright lights, the screen could maintain high luminance, which created a truly decent amazing HDR effect. Unfortunately, where the television could showcase true class, that is in scenes requiring precision, all the magic dissipates. The dimming algorithms, which we mentioned earlier, operate so aggressively that small bright objects – such as distant lights, stars, or the moon – can almost completely disappear. A glance at the test scenes from the film Pan or Sicario 2 (screens 2 and 4) shows how subtle details are dimmed to the limits of their visibility. It's a pity, as a greater number of zones could theoretically have led to significantly better results. Fortunately, there are also strengths. The QNED93A performs well in terms of colour gamut coverage, achieving around 96% of the DCI-P3 standard. As a result, colours in films appear vivid and full, and the picture does not lose intensity even in more demanding scenes. Therefore, one could say that the HDR in this model is solid, although the underdeveloped local dimming algorithms hinder its full potential.

When it comes to brightness alone, the S99H is an astronomically bright TV. Its peak brightness in film scenes can exceed 2800 nits. Whatever the scene, you can count on powerful HDR effects that are almost blinding, exactly what you expect from a top-tier screen. It is the nature of OLED panels that they cannot sustain the same extreme brightness in very bright, full‑screen frames as they can with small highlights, but the results are still excellent. In a bright scene from the film The Meg, the sun still exceeded 2200 nits. That means the S99H managed to sustain higher brightness than most Mini LED displays on the market. In terms of brightness, the S99H is currently the best OLED TV we have tested.

Colour gamut coverage

The S99H also handles colour extremely well, which is a direct result of the QD-OLED panel used here. Whether the test scenarios were synthetic test patterns or measurements taken with film material playing in the background, the results remained at a very high level. The S99H easily covers almost 100% of the DCI-P3 gamut, and for the more demanding BT.2020 colour space it reaches nearly 90%. That is absolute top-tier performance. These results match what we have seen in the new SQD-Mini-LED screens, and in real film scenes even outperform RGB Mini LED displays.

In filmmaker mode, the colour reproduction on the QNED93A was relatively accurate, although there were some reservations. In SDR content, the white balance was shifted towards warmer tones, which gave the screen a slight yellowish tint overall. The gamma, in turn, led to a slight brightness increase, making the image appear somewhat less natural, especially in scenes requiring precise shading (this is clearly visible in the comparison photo). This is not a problem that immediately stands out to every viewer, but more discerning individuals may feel that the image deviates from the aesthetics intended by the filmmakers. In HDR materials, the situation was somewhat different. The white balance, in this case, was quite good, ensuring that the whites neither leaned towards pink nor unwanted green hues. However, managing brightness turned out to be an issue. An analysis of the EOTF curve revealed that at certain moments, the television could be noticeably too dark where it shouldn't be, losing some detail and lowering the realism of the scenes. This spoiled the reception of HDR effects, which were theoretically supposed to make the biggest impression. For this reason, we decided to carry out calibration.

Samsung offers a whole host of picture modes and features, but as usual we recommend choosing Filmmaker Mode, especially if you want the most faithful rendering of the filmmakers' intent. Out of the box the TV is tuned very well, although it has minor shortcomings. These are mainly a slight drift in the white balance in SDR content and a slightly low gamma. As a result, in darker viewing conditions the picture can be a little too bright compared with the reference gamma of 2.4, which is the standard for watching films with the lights off. These are, of course, minor points, because overall colour reproduction remains at a very good level and the errors in the ColorChecker measurements are not large. However, we know that with a screen of the S99H's class you can, and arguably should, expect even more, which is why we carried out a professional calibration.

After professional calibration, the Filmmaker mode on the QNED93A has improved primarily in areas that matter most on a daily basis. We managed to correct the white balance and eliminate the yellowish tint in SDR content, which is what we watch most often – television, streaming services, or standard quality films. As a result, the colours look natural and pleasant, making the overall experience much more comfortable. We also made adjustments in HDR mode, but here the biggest issue turned out to be the EOTF curve. Although LG offers some flexibility in the settings, the television still manages brightness on its own terms. It is evident that the local dimming algorithms are not fully refined and can ruin the viewing experience by darkening parts of the image at inappropriate times. Nevertheless, it is worth opting for calibration of this model, especially the mode intended for everyday viewing.

After professional calibration, FILMMAKER mode looks practically perfect. Because Samsung offers a rich set of advanced calibration features, we were able to fine-tune the colours to an almost perfect level. Above all, we managed to even out the white balance and the gamma curve, which resulted in noticeably improved contrast and proper image modelling. In this tuned picture profile there really isn't a single thing to criticise or call a flaw. After calibration, the S99H can deliver an essentially reference-quality image.

The LG QNED93A proves to be a very solid television for everyday use. Its image processor handles scaling extremely well, which means even older films or terrestrial television benefit from increased sharpness and detail. During the screening of "The Godfather," it is clearly visible how upscaling retrieves additional details from the image – the faces of the characters and the texture of their clothing appear much clearer than in the original material.

The digital image processing also deserves praise. The television is equipped with a function for reducing unwanted colour banding and screen irregularities. It works best in the "Medium" setting – subtly smoothing tonal transitions without excessively interfering with the image. As a result, the natural film grain is preserved, and the screen does not appear artificially smooth. It is possible that in some scenes slight colour banding can still be observed, but in practice, the effect is more beneficial than with a stronger intervention from the algorithm.

The proprietary Samsung NQ4 Gen3 processor is responsible for upscaling and digital image processing. It handles upscaling lower-resolution material to 4K very well. The picture is clear without looking artificial or overly sharp. The only rather specific drawback appears with very old material recorded at 480p or below. In such cases the TV can slightly crop the edges of the picture.

The processor also copes quite well with artefacts visible in lower bit-rate material, for example heavily compressed YouTube videos. The noise reduction function effectively smooths the image and reduces posterisation, but it operates quite aggressively. It can remove not only unwanted artefacts but also some fine detail, and even natural film grain. Wanting to preserve the source material as faithfully as possible, we decided not to use it. However, if someone prefers a clean, as-smooth-as-possible picture over retaining every detail, it may prove useful.

The LG QNED93A is equipped with a 144 Hz panel. This is primarily a nod to gamers, but the fact that higher refresh rates are increasingly making their way into televisions can be viewed positively. In everyday viewing, 120 Hz remains key, and in this respect, the QNED93A performs well. The manufacturer also provides the option to adjust the picture using the TruMotion system – the De-Judder and De-Blur sliders allow you to choose between a cinematic motion character with visible frames and a complete smoothing with theatrical motion.

Another major advantage of organic OLED panels is their excellent motion handling. Thanks to the pixels' virtually instantaneous response time, the Samsung S99H exhibits virtually no motion blur. Fast-moving objects do not produce visible halos or trailing outlines, so the television performs very well for both watching sport and gaming. One characteristic of OLED screens compared with LCDs, however, is the way they render low-frame-rate material. With very slow camera movement the image can appear noticeably more 'choppy'. This can, however, be fairly effectively mitigated using a frame-interpolation system. Samsung lets you adjust judder reduction and blur reduction separately, so it's easy to find a compromise between smoother motion and preserving the cinematic character of the content.

LG QNED93A is a television that has undoubtedly been prepared with gamers in mind. Right from the outset, we get a complete set – all four HDMI ports operate in standard 2.1, so regardless of whether we connect a console, PC or amplifier, we can be assured of full compatibility. This is important, as many manufacturers still limit themselves to two ports, and here nothing hinders the entire equipment from having maximum capabilities. There is also an automatic game mode (ALLM), which automatically switches the television to the appropriate settings when the console is turned on, as well as variable refresh rate (VRR). This ensures the picture doesn't stutter or jerk, even when the frame rate drops – whether in dynamic shooters or during races.

The 144 Hz panel gives an additional advantage in computer games. While 120 Hz is sufficient for consoles, in the case of PCs, the QNED93A allows for even more – every movement, every glance to the side is refreshed faster, and this makes a difference, especially in e-sports. The manufacturer also considered HDR in gaming – the television supports the HGiG mode, which are guidelines to ensure that the lighting effects are exactly as the game developers intended. To top it off, we get Game Bar – a special information bar that appears on the screen, showing parameters in real-time. You can monitor the frame rate, active VRR functions, or the level of input lag. This solution is useful not only for settings enthusiasts but for anyone who wants to quickly check what mode the television is operating in and whether everything is working as it should.

The Samsung S99H is also a great TV for gamers. It offers almost every possible and useful feature... well, except for the obvious lack of Dolby Vision for the Xbox console. It's equipped with four full-bandwidth HDMI 2.1 ports that offer the full 48 Gbps. This lets you use VRR frame-rate synchronization and the automatic game mode (ALLM) without any problems. This year Samsung also has no issues properly supporting HGiG, so HDR setup on a console is quick and straightforward. Samsung's TVs are also known for interesting extras. In the Game Bar menu you'll find options to add an on-screen crosshair, enlarge the minimap or change the displayed image's aspect ratio (PC).

Particularly noteworthy is Samsung's Game Motion Plus feature. It's Samsung's proprietary motion-smoothing system that uses interpolation to increase smoothness in games. Input lag then rises to around 40 to 50 ms (depending on the strength of the setting), which is an excellent result compared with the competition. The system makes gameplay noticeably smoother. So if someone has their eye on a demanding game (e.g. GTA 6 😉) that runs on a console at only 30 frames per second, the S99H can display it much more smoothly than competing models.
