Samsung QLED Q80D vs LG QNED93A / QNED90A

In the context of HDR, the Samsung Q80D television, as expected, achieves very positive brightness results in the tested movie scenes, where the frame is filled with light, reaching values from 600 to 900 nits, allowing for a great juiciness of the image. Such results enable the user to feel the difference between HDR and SDR quality. Unfortunately, problems arise in situations where small light effects occur against a dark background. In such cases (e.g., the 4th test screen from the film Sicario 2), a noticeable drop in brightness is observed, which is caused by the large size of the dimming zones used here. This limitation, combined with the dimming algorithm, affects how the television handles small bright elements on a dark background. At that point, we may experience an undesired lack of brightness, and the HDR effect resembles that of SDR.

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.

In "Filmmaker" mode, which is the best choice right out of the box, the Samsung Q80D television shows solid colour reproduction. For SDR content, a noticeable drop at the start of the gamma curve suggests that details in dark scenes may be less clear, affecting the overall viewing experience. Regarding white balance in SDR content, while generally correct, significant drops in blue at screen coverage above 70% can result in less natural shades in both bright and dark scenes. Users may notice that some blue elements in the image may appear less vibrant, and the overall colour will have a warmer hue.

In HDR content, the EOTF curve being above the reference line for most of the time indicates that the television may struggle to accurately reproduce brightness and details in the brighter parts of the image, which can be detrimental for the viewer. It is also worth noting the significant drop at the start of this chart, indicating that the television has difficulty reproducing brightness in the darker parts of the image, as seen in the contrast and black test, where several scenes were unable to show the full capabilities of the television’s brightness. In terms of its white balance, the initially good performance on the graph is promising, but the steep decline in red, coupled with a significant increase in blue, can lead to inaccuracies in reproducing some skin tones and other key colours. This phenomenon may be noticeable to viewers in scenes where colour details are crucial.

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.

The movie mode after calibration looks significantly better than the one you see right out of the box. Samsung offers an advanced range of calibration tools in its televisions. Among them are 2- and 20-point greyscale adjustment and CMS (Color Management System). Both in HDR and SDR mode, white balance has improved significantly, although there are slight errors at the end of the graph for HDR content. Contrast has also been greatly improved, and the gamma curve responsible for SDR shows better results. However, when it comes to HDR, the EOTF curve on the television appears to be at an ideal level at first glance. However, when we dig a bit deeper and enable the EOTF graph while watching films, we may notice that all the lines of the curve are above the reference line. You could even say that the television is "cheating" when playing film material. Such a situation, where the EOTF curve is above the reference line, causes the screen – although it may appear brighter, which some users might find appealing – to lose detail in the darker parts of the image. In practice, this means that in scenes with a lot of shadows or dark elements, the television is unable to accurately render the details that should be visible.

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.

Samsung Q80D performs very well with low-quality materials. The noise reduction works on the principle of gentle gradation, making it very effective in smoothing out unwanted image disturbances. Unfortunately, this same effectiveness also causes it to blur elements that shouldn't be smoothed, such as film grain. For those who prioritise a plastic, smooth image, this can be seen as a significant advantage, especially with lower-quality content.

In terms of image scaling, Samsung Q80D stands out positively in this aspect, significantly enhancing the viewing comfort. The TV handles the conversion of lower-resolution materials, improving their quality and details. For example, in the attached image featuring a model, there are no visible artefacts or excessive fraying of branches, which demonstrates advanced image processing technology.

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.

The Samsung Q80D television stands out very positively in terms of motion fluidity and minimizing blur, mainly due to the 120Hz panel and above-average panel response time. Users have two options for adjusting fluidity: "Motion Smoothing," which allows for adjustments in a 10-step scale, and "Blur Reduction," particularly effective at higher refresh rates, improving the sharpness of fast-moving objects. In the UFO test, there is no blurring behind the moving object, and the image is not cloned forward, indicating the absence of an overshoot effect.

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.

The Samsung Q80D TV is a real gem for gamers. It is equipped with four HDMI 2.1 ports, which is a rarity, especially in this price range. This allows users to enjoy features such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and 120Hz at 4K resolution. These features ensure smoothness and responsiveness of the image, which is a key aspect during dynamic gameplay. The TV also supports HGIG (HDR Gaming Interest Group), enabling optimal HDR content display in games. Additionally, it comes with a Game Bar, providing quick access to gaming settings. Users with Nvidia graphics cards will also be pleased with the implementation of G-Sync. This feature eliminates stuttering and screen tearing. The only downside is the lack of support for Dolby Vision, which may be disappointing for users looking for that HDR format. It's also worth mentioning that since 2022, thanks to the collaboration with Microsoft, Samsung TVs offer the Xbox Game Pass app, allowing for cloud gaming. This is an added bonus for gamers who want to take advantage of a wide library of games without needing a console.

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.
