Sony X75WL vs LG NANO81A / NANO80A

The luminosity chart for the X75WL Sony television showed a maximum value of 350 nits, which is unfortunately not an impressive result. The television does not surprise with its brightness, and all the HDR scenes we tested lacked depth and the appropriate light effect that should accompany HDR content. Additionally, the poor coverage of the DCI-P3 colour gamut makes it difficult for the television to reproduce rich colours, which significantly affects the overall viewing experience of HDR content. The lack of adequate brightness and weak colour coverage mean that HDR effects are very limited in this model.

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.

Colour reproduction tests for the model Sony X75WL are carried out in movie mode, which offers the best image settings, but it also has its flaws. The biggest problem with the X75WL Sony is the white balance – for both HD and 4K HDR content – which is characterised by a dominance of blue. As a result, the entire image feels too cold. The colour checker confirms these errors, showing that the colours lean towards cooler tones. In terms of brightness characteristics, the contrast gamma is at a fairly decent level, however, the same cannot be said for the EOTF curve. There are significant issues with maintaining appropriate brightness – the image is either overly bright or too dim, which impacts the visual perception of content.

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.

X75WL Sony is one of those cases where image calibration may not be highly spectacular, but it offers a very good improvement in the perception of colours. The white balance, for both HD and 4K materials, has been significantly improved – there is no longer a strong dominance of cooler shades. The gamma curve also appears more stable, which translates into better image quality. However, the biggest issue remains the EOTF curve, which is responsible for brightness in 4K materials. Due to the technological limitations of the television (IPS panel and lack of local dimming technology), it is hard to speak of a significant improvement, as we cannot extract more from this model. Despite these limitations, the tonal quality of the image has been significantly enhanced.

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.

In the case of low-quality tonal transitions, the television Sony X75WL performs poorly. The lack of any feature to improve tonal transitions results in noticeable imperfections in colour gradation. However, one can credit the quite good digital processing – the image is displayed without overscan, and overall it looks relatively good thanks to the added slight sharpness, which some users may appreciate.

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 X75WL Sony television is equipped with a 60 Hz panel, making it more suitable for watching films than for dynamic gaming. This model features a motion smoothing function called Motionflow, which allows the user to adjust the picture on a 10-point scale. Smoothness is responsible for adding intermediate frames, thereby increasing the fluidity of motion, while the image becomes more theatrical, minimising the cutting effect. Clarity reduces motion blur, which is particularly useful in fast scenes such as sports or dynamic actions in films. With this feature, users can adjust the fluidity and sharpness of motion to their own preferences.

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.

X75WL is not the best television for gamers. It only has the ALLM (Auto Low Latency Mode) feature and a basic Game Bar, which are not enough to satisfy more demanding users. In this price range, one could expect support for features like VRR or 120 Hz refresh rates - although in FULLHD, which are already standard - unfortunately, they are lacking here. This is a major downside for Sony, as the competition offers much more for gamers in a similar budget.

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.
