Sony X90L vs LG QNED93A / QNED90A

HDR on the Sony X90L television looks promising. The luminance chart indicated that the TV has a solid power reserve, achieving a maximum of 1000 nits in synthetic tests. But how does this perform in real-world scenarios? In scenes such as the opening of Life of Pi or the final sequence from The Meg, the TV is capable of delivering that power on HDR content, reaching around 800 nits. Unfortunately, displaying small light elements on a black background, like in the scene from Sicario 2, presents greater challenges for the X90L – here the results reach around 600 nits. Nevertheless, when looking at competitive models with mini-LED technology, the effect looks very good and can shine enough to impress us. The colour gamut coverage is also noteworthy, with a result of 96% for DCI-P3 and 76% for BT.2020, which indicates good colour reproduction in HDR content.

Although the number of local dimming zones in the LG QNED93A hasn’t directly translated to noticeably better contrast, it’s hard to deny this model one thing – it’s 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 whites or bright lights, the screen was able to maintain high luminance, providing a truly decent amazing HDR effect. Unfortunately, where the TV could show true class, that is in scenes requiring precision, all the magic dissipates. The dimming algorithms we mentioned earlier operate aggressively enough that small, bright objects – like distant lights, stars, or the moon – can almost completely disappear. Just look at the test scenes from the film Pan or Sicario 2 (screens 2 and 4) to see how subtle details are dimmed to the limits of their visibility. It’s a pity because a greater number of zones could theoretically translate to significantly better performance. Fortunately, there are also strong points. The QNED93A performs well in terms of colour gamut coverage, achieving around 96% of the DCI-P3 standard. As a result, colours in films look rich and full, and the image doesn’t lose intensity even in more demanding scenes. So, it can be said that the HDR in this model is solid, although the underdeveloped local dimming algorithms hinder its full potential.

The best mode on Sony televisions is the IMAX Enhanced mode. Although IMAX is mainly associated with the cinema experience, the colour reproduction out of the box is average here. In the case of lower quality materials, such as HD – regular television or YouTube – it's worth paying attention to the white balance. It suffers from a shortfall in red and excessive dominance of blue, which gives the image a pinkish hue. The brightness characteristic, or gamma, for HD content is quite acceptable, but a slight boost can cause the image to appear washed out and look as if it’s behind a light fog.

For 4K HDR content, the situation is somewhat different. The white balance shows a significant boost in blue, which makes the image unnaturally sharp and gives it an artificial feel. Such an exaggeration in colour reproduction may not appeal to everyone, especially if one prefers more realistic tones. Additionally, the EOTF curve in Sony X90L looks quite acceptable at first glance. However, at the end of the graph, there are certain fluctuations that suggest the television is trying to maintain the correct brightness to avoid overexposing larger elements.

In film mode (more specifically Filmmaker), the colour reproduction in the QNED93A was relatively accurate, although there were some reservations. In SDR content, the white balance leaned towards warmer tones, resulting in a slight yellowing across the entire screen. Gamma, on the other hand, led to a slight lightening of the image, making it look a bit less natural, especially in scenes that required precise shading (this is evident in the comparison photo). This isn't a problem that immediately stands out to every viewer, but more discerning individuals may feel that the image deviates from the intended aesthetic of the filmmakers. In HDR materials, the situation looked a bit different. The white balance here was quite good, ensuring that whites did not take on pink or unwanted green hues. However, the brightness management turned out to be an issue. An analysis of the EOTF curve revealed that at certain moments, the television could be distinctly too dark where it shouldn't be, losing some details and lowering the realism of scenes. This detracted from the HDR effects, which were theoretically meant to be the most impressive. For this reason, we decided to conduct a calibration.

Sony offers many tools for improving picture quality, including two extra picture modes that we decided to use during testing and apply calibration to. This solution greatly simplifies the calibration process and is very effective, provided you have the right tools. In the case of HD content, white balance was almost perfectly aligned – only one shade of grey exceeds an error value of "1", which is a great result. The same can be said for the brightness characteristic (gamma), which presents almost perfectly, with microscopic deviations of around 0.01.

For 4K HDR content, the situation is not as ideal. Although white balance has been significantly improved, it was not possible to completely eliminate the dominance of blue. Nevertheless, errors in the Colour Checker test only occasionally exceed the value of "2", which means that picture distortions are practically unnoticeable. When it comes to the EOTF curve, it's worth activating the filter in the top right corner "EOTF in Films" – the graph looks correct, but the TV struggles with illuminating very small elements, which is due to the limited number of backlight zones. Despite these minor errors, it's thanks to the calibration that the IMAX Enhanced mode in the Sony X90L makes watching movies feel like a true cinema experience.

After professional calibration, the Filmmaker mode in the QNED93A has improved primarily where it matters most in everyday use. We managed to straighten the white balance and eliminate the yellowish tint in SDR content, which is what we watch most often – television, streaming services, or standard quality movies. As a result, the colours look natural and pleasant, making the overall viewing experience significantly more comfortable. In HDR mode, we also made corrections, but here the biggest issue turned out to be the EOTF curve. Although LG provides some leeway in the settings, the television still controls brightness on its own terms. It's clear that the local dimming algorithms are not fully refined and can ruin the viewing experience by dimming parts of the picture at inappropriate moments. Nevertheless, it’s worth opting for calibration of this model, especially the mode intended for everyday viewing.

The Sony X90L television features a smooth tonal transition function known as Gentle Gradation, which is incredibly effective. Even at the "low" setting, the effects are satisfactory, but at the "medium" setting, it works like a dream – we recommend using this option for the best results. The image scaling on the Sony X90L is simply excellent. The image is not overly sharpened, which gives a natural effect and makes everything look cohesive. It's clear that the engineers have really put effort into this aspect, creating a solution that impresses and performs well in everyday use. This means that even when watching content like regular television or YouTube, where the image is by nature not stunning, you can enjoy a smooth, coherent, and visually pleasing experience.

The LG QNED93A turns out to be a very solid television for everyday use. Its image processor performs excellently with upscaling, making even older films or free-to-air television sharper and more detailed. During the screening of 'The Godfather,' it’s clearly visible how upscaling brings out additional details from the image – the characters’ faces and the texture of their clothing look significantly clearer than in the original material.

The digital image processing also deserves praise. The television is equipped with a function that reduces unwanted colour banding and screen irregularities. It works best in the 'Medium' setting – subtly smoothing tonal transitions without overly interfering with the image. This way, the natural film grain is preserved, and the screen does not appear artificially smooth. Perhaps in some scenes, slight colour banding can still be noticed, but in practice, the effect is more advantageous than with a stronger intervention from the algorithm.

Sony X90L with a 120 Hz display is an excellent choice for both gamers and film enthusiasts. The television is equipped with the Motion Flow smoothing feature, which allows for adjusting motion smoothness using two sliders: "smoothness" and "clarity". The "smoothness" slider controls the level of motion fluidity, which affects the reduction of image stuttering, while "clarity" is used to reduce blurriness and enhance motion sharpness, which is especially useful in dynamic scenes.

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

Sony X90L is a TV that performs well in terms of compatibility with consoles and features for gamers. Its 120 Hz panel and two HDMI 2.1 ports with a bandwidth of 48 Gb/s allow for smooth playback of high-resolution games at high frame rates. Gamers can also take advantage of the ALLM feature, which automatically switches the TV to low latency mode, and VRR, which ensures smooth gameplay without frame tearing. The Game Bar is an added bonus – an intuitive tool that provides quick access to essential settings and gaming features, making it easier to control the gameplay.

Unfortunately, when it comes to HDR in games, the Sony X90L has its limitations. It lacks support for HGiG, a standard that many gamers consider crucial for accurate HDR representation in games. While the TV supports Dolby Vision, which theoretically could enhance image quality in games, the practical implementation of this feature is problematic. Dolby Vision in game mode comes with very high input lag, making gameplay less comfortable and precise movements more difficult. Additionally, Dolby Vision cannot be enabled alongside VRR. This means that despite numerous advantages, gamers seeking the perfect HDR in games may feel unsatisfied.

LG QNED93A is a television that has undoubtedly been designed with gamers in mind. Right from the start, we get a complete package – all four HDMI ports operate in 2.1 standard, so whether we connect a console, a PC, or a receiver, we have full compatibility. This is important because many manufacturers still limit themselves to two ports, and here nothing stands in the way of having maximum capabilities for all the equipment. There’s 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 means the image doesn’t stutter or glitch, 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 enough for consoles, the QNED93A allows PCs to push even more – every movement, every glance to the side is refreshed faster, which makes a difference especially in e-sports. The manufacturer also considered HDR in games – the television supports HGiG mode, which are guidelines intended 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 called up on the screen that shows parameters in real time. You can check the frame rate, active VRR functions, or input lag levels. 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.
