Samsung QLED Q80D vs LG QNED93A / QNED90A

In the context of HDR, the Samsung Q80D television delivers impressive brightness performance in tested movie scenes, achieving levels between 600 to 900 nits when the frame is filled with light. This brightness enhances the vibrancy of the image and allows users to perceive the differences between HDR and SDR quality. However, challenges arise when small light effects appear against a dark background. For instance, in specific scenes, such as test slide 4 from Sicario 2, there is a noticeable drop in brightness due to the larger size of the dimming zones employed by the television. This limitation, coupled with the local dimming algorithm, affects the TV's ability to accurately display small bright elements on dark backgrounds, leading to a lack of brightness that can diminish the HDR effect, making it appear similar to SDR quality.

Although the number of local dimming zones in the LG QNED93A did not directly translate to a noticeably better contrast, one cannot deny that this model is brighter than its predecessor. In synthetic tests, we recorded values around 1400-1500 nits, and more importantly, these results are reflected in real movie scenes. In full-screen sequences flooded with white or bright lights, the screen was able to maintain high luminance, which produced a truly decent incredible HDR effect. Unfortunately, where the television could show its true class, namely in scenes that require precision, all the magic evaporates. The dimming algorithms we mentioned earlier are aggressive enough that small bright objects—such as distant lights, stars, or the moon—can almost completely disappear. Just look at the test scenes from the movie Pan or Sicario 2 (screens 2 and 4) to see how subtle details are dimmed to the brink of visibility. It's a shame, because a greater number of zones could theoretically lead to significantly better results. Fortunately, there are also stronger points. The QNED93A performs well in terms of color gamut coverage, achieving around 96% of the DCI-P3 standard. As a result, colors in movies look vivid and full, and the picture does not lose intensity even in more demanding scenes. So it can be said that the HDR in this model is solid, although the unfinished local dimming algorithms hinder its full potential.

In "Filmmaker" mode, which is considered the best out-of-the-box choice, the Samsung Q80D demonstrates solid colour reproduction. However, when viewing SDR content, there is a visible drop at the beginning of the gamma curve, suggesting that details in dark scenes may be less clear, which could detract from the overall viewing experience. While the white balance in SDR content is generally accurate, significant drops in blue at screen coverage above 70% can lead to less natural hues in both bright and dark scenes. Users might notice that some blue elements appear less intense, resulting in a warmer tint to the colour presentation.

For HDR content, the EOTF (Electro-Optical Transfer Function) curve being above the reference line most of the time indicates that the TV may struggle to accurately reproduce brightness and detail in the brighter areas of the image, which can be less than ideal for viewers. Additionally, there is a notable drop at the beginning of this graph, signifying the TV's difficulty in reproducing brightness in dark areas; this limitation is apparent in contrast and black tests, where several scenes fail to showcase the TV's full brightness potential.

Regarding white balance, the initial performance on the chart is promising, however, a sharp drop in red, coupled with a significant rise in blue, may lead to inaccuracies in reproducing certain skin tones and other key colours. This issue can be particularly noticeable in scenes where colour details are essential, potentially affecting the viewer's overall experience.

In movie mode (specifically Filmmaker), color reproduction on the QNED93A was relatively accurate, although it wasn't without critiques. In SDR content, white balance leaned towards warmer tones, resulting in a slight yellowing across the entire screen. Gamma, on the other hand, led to a slight brightening of the image, making it look a bit less natural, especially in scenes requiring precise shading (this is evident in the comparison picture). This isn't a problem that immediately stands out to every viewer, but more discerning individuals may feel that the picture deviates from the aesthetic intended by the filmmakers. In HDR materials, the situation looked somewhat different. The white balance presented itself quite well here, ensuring that whites didn't lean towards pink or unwanted shades of green. However, brightness management proved to be an issue. Analysis of the EOTF curve revealed that at certain moments the television can be noticeably too dark where it shouldn't be, losing some detail and reducing the realism of scenes. This detracted from the experience of HDR effects, which were theoretically supposed to be the most impressive. For this reason, we decided to carry out calibration.

After calibration, the Samsung Q80D’s Movie mode offers a noticeable improvement over the out-of-the-box settings. Samsung provides an advanced suite of calibration tools, including 2- and 20-point grayscale adjustments as well as a CMS (Colour Management System), allowing for precise control over both SDR and HDR content. The calibration greatly enhances white balance, although minor errors remain in HDR content toward the end of the graph. Contrast has also improved, and the gamma curve for SDR content now aligns well with expected levels.

In HDR, the EOTF curve initially appears to sit ideally, however, closer examination reveals all lines are slightly above the reference line, a phenomenon that may be seen as the TV "enhancing" brightness for added appeal. This effect, however, comes at a cost: while the screen may appear brighter overall, it sacrifices detail in darker areas, leading to a loss of subtle textures in shadowed scenes. As a result, scenes with deep shadows or dark elements may lose some finer visual details that would enhance the viewing experience.

After professional calibration, the Filmmaker mode on the QNED93A gained the most where it matters most in everyday use. It was possible to adjust the white balance and eliminate the yellowish tint in SDR content, which we watch most often – television, streaming services, or standard quality films. This makes colors look natural and pleasant, and the overall experience is much more comfortable. In HDR mode, we also made adjustments, but the biggest problem here turned out to be the EOTF curve. Although LG provides some leeway in the settings, the television still manages brightness on its own terms. It is evident that the local dimming algorithms are not entirely refined and can spoil the viewing experience by dimming parts of the image at inappropriate moments. Nonetheless, it is worth opting for calibration of this model, especially the mode intended for daily viewing.

Performing admirably with low-quality content, the Q80D’s noise reduction feature uses gentle gradation to smooth out unwanted image disturbances. However, this technique can also soften certain details, like film grain, that some viewers might prefer to retain. For those who appreciate a more polished and smoother image, particularly with lower-resolution material, this becomes a significant advantage.

In terms of image scaling, the Q80D stands out, enhancing both quality and detail for lower-resolution media. Advanced processing technology reduces artefacts and maintains clarity, as seen in the clean edges and absence of fraying in elements like branches during test scenes. This capability makes it an excellent option for viewers seeking an enhanced and comfortable viewing experience, even with less-than-ideal content quality.

LG QNED93A proves to be a very solid television for everyday use. Its image processor handles scaling excellently, ensuring that even older movies or terrestrial television gain sharpness and detail. During the screening of "The Godfather," it's clearly visible how upscaling pulls extra details from the image – the characters' faces and the texture of the 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 color banding and screen irregularities. It works best in the "Medium" setting – subtly smoothing tonal transitions without over-interfering with the image. This way, the natural film grain is preserved, and the screen doesn't appear unnaturally smoothed. Perhaps in some scenes, you can still notice slight color banding, but in practice, the effect is more favorable than with a stronger intervention from the algorithm.

Motion smoothness and blur reduction are standout features on the Samsung Q80D TV, thanks to its 120Hz panel and impressive response time. Users have two customisation options to enhance smoothness: "Motion Blur Reduction," adjustable on a 10-step scale for refined control, and "Blur Reduction," which works particularly well at higher refresh rates, enhancing clarity in fast-moving scenes. In the UFO test, the panel performs without trailing or forward-cloning effects, indicating a lack of overshoot and delivering clear, sharp visuals during rapid motion.

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 seen as a positive development. In everyday viewing, 120 Hz remains key, and in this regard, the QNED93A performs well. The manufacturer also provides the option to adjust the image through the TruMotion system – the De-Judder and De-Blur sliders allow you to choose between a cinematic motion character with visible frames and a fully smoothed theatrical motion.

The Samsung Q80D is a fantastic choice for gamers, offering a range of advanced gaming features that are rare in this price category. Equipped with four HDMI 2.1 ports, it enables key functionalities like ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and 120Hz support at 4K resolution, ensuring smooth and responsive visuals, essential for fast-paced gaming. The TV also supports HGIG (HDR Gaming Interest Group) for optimal HDR display in games and includes a Game Bar for quick access to gaming settings. Gamers with Nvidia graphics cards will appreciate the G-Sync support that eliminates screen stuttering and tearing.

Although it lacks Dolby Vision support, which may disappoint those seeking that HDR format, Samsung has partnered with Microsoft since 2022 to provide the Xbox Game Pass app, enabling cloud gaming access to a wide library of games without 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 at standard 2.1, so whether we connect a console, PC, or receiver, we can be sure of full compatibility. This is important because many manufacturers still limit themselves to two ports, and here nothing prevents all equipment from having maximum capabilities. There’s also an automatic game mode (ALLM), which switches the television to the appropriate settings when the console starts up, as well as variable refresh rate (VRR). This ensures that the image does not stutter or tear, 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, which makes a difference especially in e-sports. The manufacturer also considered HDR in games – the television supports the HGiG mode, which provides guidelines to ensure that the lighting effects are exactly as intended by the game developers. For dessert, we get Game Bar – a special informational strip invoked 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 verify what mode the television is operating in and whether everything is working as it should.
