LG NANO81A / NANO80A vs Samsung OLED S95H (S99H) (QD-OLED)

If you are counting on HDR in the NANO81A to bring tears to your eyes, I must disappoint you. This television is simply too dark to truly show what this format is all about. With a brightness of only 250 nits, HDR exists here mainly on paper. In practice, during viewing, it is very difficult to distinguish whether we are watching high dynamic range content or regular SDR – it simply lacks that ‘punch’ of light in the bright parts of the image. However, to give credit where it’s due, we do have a glimmer of hope here – and quite a clear one at that. It concerns the colour gamut coverage. Here, the NanoCell filter shows that it is not just marketing nonsense. Our measurements indicated that the coverage of the DCI-P3 space is around 88%. This is a really solid result that places this model significantly higher than typical budget options based on standard white LEDs without any filters. Of course, it still falls short of the level of quantum dot (QLED) TVs or advanced panels with PFS filters, but for this price point, the colours are surprisingly saturated and vibrant. It's just a shame that this low brightness prevents them from fully ‘spreading their wings’ with the Nano filter.

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.

For every film fan, the natural choice in LG televisions is the Filmmaker Mode. Its aim is to display images as the director intended – without unnecessary "enhancements". Unfortunately, in the case of our test unit NANO81A, the factory settings left something to be desired. The main issue turned out to be the white balance. Measurements showed a distinct deficiency of blue colour, which in practice meant that many scenes had a slightly yellowish, even "yellowed" tint. The white was not perfectly pure, which detracted from the freshness of the image. Additionally, brightness management was also not ideal – the factory-set gamma was too low. The picture often appeared oversaturated, as if overly lifted from the shadows, which caused it to lose naturalness and depth. Fortunately, LG, even in this relatively low price category, does not block access to advanced settings. The calibration possibilities of this model are enormous, which is a big plus for those who enjoy "digging" in the menu. We decided to approach the topic in our own way and see how much we could squeeze out of this panel with professional 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 calibration, the NANO81A is a completely different television. What LG offers in terms of image enhancement tools even in such an affordable model deserves a big plus. We managed to completely eliminate that annoying yellowing of whites and make the colours natural, vibrant, and simply "true". In SDR content (that is, regular television, YouTube, or older films), the picture now looks worlds better – it is clear, well-balanced, and no longer strains the eyes with strange hues. It is clear that this panel has significant potential, which is simply wasted by poor presets out of the box. However, we do have one serious reservation that calibration cannot fully overcome – it concerns brightness management in HDR mode. LG's algorithm in this model is constructed very conservatively. The television intentionally dims the HDR picture to avoid overexposing the already weak blacks of the IPS panel. The programmers faced a choice: either to provide more light and accept that the blacks would become light grey or to reduce the brightness to maintain any contrast. They chose the latter. Nevertheless, after our adjustments, watching anything on the NANO81 is significantly better.

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.

It often happens that cheap 4K panels mercilessly bring to light all the "dirt" and imperfections of lower-resolution content. However, with the LG NANO81A, the situation is quite different. This is truly a solid performer when it comes to handling content that is far from ideal. The built-in processor does a great job with upscaling. Even older recordings look quite decent on this screen – the image is coherent, cleaned of digital noise, and simply pleasant to the eye. A significant advantage is the gradation reduction feature that you will find in the settings. It is extraordinarily effective in combating colour banding, which is a lifesaver when watching materials with a low bitrate, for instance, from some streaming services or older files from the web. However, it is worth maintaining a certain level of caution. Since we are dealing with a less powerful chip than in LG's top models, setting this option too aggressively may sometimes result in minor artefacts or slight blurring of details. Despite this risk, I definitely encourage experimenting with this feature - in many cases, it can save the viewing experience and make low-quality material fully watchable.

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.

When it comes to motion fluidity, the NANO81A unfortunately has a hard time. The television is based on a panel with a refresh rate of 60 Hz. If you are looking for perfect sharpness in dynamic football matches or fast action games, you may feel a bit disappointed. With such a low native refresh rate, fast objects on the screen will always be a little blurred.

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.

NANO81A is unfortunately not hardware designed for e-sports. The lack of support for a 120 Hz signal is a fact that users planning to purchase this model simply have to come to terms with. Nevertheless, LG's engineers have made an effort to maximise the potential of this 60 Hz panel, offering a set of features that genuinely enhance the gaming experience. Firstly, the television supports VRR technology (within the range of 48-60 Hz) and ALLM. As a result, the image remains stable and does not "tear", and the device automatically switches to low-latency mode as soon as it detects a signal from a console. Managing these settings is extremely simple thanks to a dedicated system overlay, which allows for quick viewing of parameters without leaving the game. A very significant advantage is the support for the HGiG format. This solution is crucial for owners of modern consoles because it enables the television to correctly "understand" the intentions of game developers regarding HDR tone mapping. In practice, this helps avoid the effect of "blown-out" bright spots, such as clouds or light sources, which is unfortunately a common issue in budget LCD televisions.

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.
