LG QNED80A6A (VA) vs Dreame S100

Let's talk now about how this TV shines. If you expect dazzling light effects, we need to cool your enthusiasm. The LG QNED80A is a moderately bright television. Our measurements in most movie scenes indicated values around 350-400 nits. That's not enough to speak of a full, cinematic HDR experience and the sense of that famous "high dynamic range" that flagship products offer. However, brightness is not everything. Although the QNED80A is not a "light monster," it makes up for it in another key category: colors. Here, the PFS technology comes into play, which LG marketers hide under the name QNED/NanoCell. Thanks to this process, the TV offers a significantly wider color palette than classic LCD designs. In our tests, the coverage of the cinematic DCI-P3 palette reached a solid 93-94%. What does this mean for you? That even at lower brightness, when watching movies in HDR, the colors will be vivid, deep, and properly saturated. The image is not washed out but lush, which is a significant advantage in this price range.

The Dreame S100 is a relatively bright television. In movie mode, the brightness we measured reached about 600 nits. This is a really good result, although not the highest, considering the capabilities of the competition in this price range. In fullscreen scenes, it is evident that the television can generate an image that strikes with brightness. Unfortunately, when more complex scenes appeared on the screen, the local dimming algorithm in this model tried above all to maintain the deepest blacks. However, this came at the expense of HDR effect – and in a drastic way. In such scenes, the brightness of bright elements dropped below 100 nits, which is a truly tragic result, far from any HDR effect. This aspect can be improved, though not without any "buts." It is enough to change the local dimming setting in the television's menu, but then the blacks in such scenes simply turn gray. It’s a pity that Dreame could not refine the local dimming algorithms better, and the S100 is another example that the mere number of local dimming zones does not always translate into better image quality. As a consolation, it is worth adding that the Dreame S100 is advertised as a "QLED" television, although in reality it utilizes a PFS LED filter. As a result, the colors are appropriately saturated, and the color gamut coverage we measured exceeded 94% of the DCI-P3 palette.

It might seem that since the QNED80A is one model, it should offer the same picture regardless of the version. However, practice shows something completely different. Analyzing the variant with a VA panel in the best factory setting – that is, in Filmmaker Mode – we noticed a specific characteristic. This TV “out of the box” serves us a picture with a clear dominance of red and a deficiency of blue. The overall image is very warm, almost hot. Many users might describe this as a “too cinematic” image, approaching sepia. Additionally, there's the issue of the gamma curve – the TV tends to slightly, artificially brighten scenes (the gamma is too low), causing the picture to lose some of its plasticity. The good news is that these are not flaws of the panel, but merely of the software. As always in our tests, we carried out a professional calibration, which completely eliminated these shortcomings, restoring the natural white balance and correct saturation.

We tested the Dreame S100 in "movie" mode and definitely recommend using this setting for watching all kinds of content. Interestingly, in the deeper settings of the TV, we also find a dedicated "Filmmaker" mode, which is available today from almost every manufacturer. However, in the case of the Dreame S100, we do not recommend using it – it blocks all image-related settings and does not allow any configuration in the menu - not even motion smoothing. So how do the factory colors perform on the S100? Not too bad, but also not great. The TV itself was quite heavily tinted with blue components, which is clearly visible in our white balance measurements. This caused the image to be artificially brightened, and the colors had a slight bluish tint. This is confirmed by the Color Checker palette, which showed how color samples leaned towards blue, generating quite significant color errors. The image in HDR mode looked definitely better, where color errors were not as prominently visible, though they still fell far from ideal. Here, the white balance was also too heavily skewed towards the blue color, which caused quite significant errors in color reproduction.

Was it worth spending time on calibration? Definitely yes. We managed to tame the initially too warm white balance and, most importantly, correct the gamma curve. The TV stopped artificially brightening scenes, which added depth to the image. The biggest improvement is visible in SDR content, meaning when watching regular television, YouTube, or in games without HDR. Here, the QNED80A shows its class – color reproduction errors (DeltaE) dropped below a value of 2. In technical terms, this means that the errors are practically unnoticeable to the human eye. The image in everyday use has simply become very attractive, natural, and correct. The difficulties begin with HDR content. Even though we managed to improve the white balance, the EOTF curve graph (responsible for brightness at various levels) shows that the TV still "interprets" the image in its own way. This is due to the nature of the edge-lit local dimming used and the fact that LG gives the calibrator a very limited range of control over this parameter. In short: the TV struggles to hide its hardware shortcomings, sometimes ignoring our commands. Nevertheless, the final image is much more accurate and pleasant to the eye than in factory settings, even if it still falls short of studio ideal.

The Dreame S100 turned out to be a device very susceptible to professional calibration. In its menu, we found a whole array of advanced options that allowed us to effectively correct factory errors. Thanks to advanced white balance correction – both in SDR and HDR content – we completely eliminated excess blue components. The image immediately became much more natural and pleasant to view. After fully tuning the colors, errors in the Color Checker test dropped below Delta E values of 2-3. For the average viewer, this means that any color distortions have become nearly impossible to notice with the naked eye. This is a really nice surprise, as often new brands in the television market have significant problems with proper implementation and functioning of sliders in the calibration menu. Here, everything worked as it should. The only thing we need to criticize is the way the television manages its brightness in HDR. Due to the specific nature of the local dimming algorithms, we observed anomalies in the EOTF curve we measured. In the areas where high highlights should appear, there is a slight uplift of the curve above the reference line. In practice, this results in unnatural brightening of some of the brightest elements in movies or games. Despite this minor flaw, professional calibration brings a huge, very positive change to this model.

In this category, the QNED80A proves to be a real "dark horse." It's a fantastic, affordable television for those who often watch lower quality materials – for example, from traditional cable TV. The processor used here handles upscaling exceptionally well, meaning it enhances low resolution to native 4K. The image after processing is natural, smooth, and most importantly – not overly jagged or artificially sharpened. In the menu, we also find a dedicated option for smoothing tonal transitions in low-quality material. This feature works really effectively, eliminating the annoying "banding" of colors in heavily compressed video. However, we must remain vigilant. Remember that we are not dealing with a top-tier processor known from flagship OLED models. In more challenging scenes, the system may struggle and introduce minor artifacts or distortions. Nevertheless, it's definitely worth giving this feature a chance, as in most cases, the improvement in quality is noticeable to the naked eye.

The scaling and digital processing in the Dreame S100 is handled by a technology that the manufacturer proudly calls Dreamind™ Pro AI. However, it is essential to clarify that this is not a proprietary processor but merely a marketing name for a chip from MediaTek – specifically, the model MT5889. Unfortunately, we are talking about quite an outdated unit, from the time when MediaTek lagged significantly behind the competition in terms of performance. This, unfortunately, has a direct impact on the image, as this chip is responsible for that as well. The upscaling in the S100 is rather mediocre, and the processor tends to strongly and artificially sharpen edges (fortunately, this can be somewhat tempered with the sharpness slider in the menu). In the options, we also find a "Contour Smoothing" function, which theoretically is supposed to improve tonal transitions. In practice, it brings almost no improvement – setting it to any level rarely eliminates visible color banding but can unnecessarily blur elements of the image that should remain sharp.

A separate problem is the phenomenon of overscan (clipping the edges of the frame), which is almost always visible here. Although there is an option to set the screen to display the full frame in low-resolution materials, it requires activating the aforementioned Filmmaker mode. And as you already know, this mode completely blocks any other adjustments in the image menu. In our test tables, we noted that the television offers the option to disable overscan, as technically such a feature exists in the system – however, in everyday use, with reasonable image settings, you will not be able to take advantage of it.

We move on to a matter that may be decisive for many. Unfortunately, here we must point out the biggest "Achilles' heel" of the QNED80A model. This TV is equipped with a panel that has a native refresh rate of 60Hz. There's no point in hiding it – at this price, we expected more because we know that Chinese manufacturers can offer 120Hz screens for similar money. Due to this parameter, dynamic scenes in sports or fast-paced games are not the strong suit of this screen. Fortunately, LG has equipped the TV with a proven smoothing system called TruMotion. It works quite well with film material (24 frames). We suggest playing around with the De-Judder slider – from our experience, setting it in the range of 2-4 provides the best compromise: motion becomes smoother while still looking natural, without the artificial "TV theater" effect.

When it comes to motion fluidity, the Dreame S100 performs really well. It features a panel with a 144 Hz refresh rate, although in reality, the vast majority of users using it in a traditional way will still be limited to 120 Hz (because today's equipment, apart from PCs, only allows for such values). Thanks to the high refresh rate, the image in motion remains really sharp, largely due to the well-functioning MEMC fluidity enhancer. In the menu, we find predefined modes that allow the TV to efficiently add artificial frames, which effectively improves the fluidity of dynamic sports shots, but also helps get rid of image stuttering in film and series materials recorded at 24 frames.

Since we have established that the QNED80A is a 60Hz panel television, we must say it directly: we will not be playing here at 120 frames per second in any resolution. Does this disqualify the device in the eyes of gamers? Not necessarily, especially for "casual" gamers. LG has decided to sweeten this technical limitation by packing in quite a few useful features. We have support for VRR (Variable Refresh Rate) ranging from 48-60Hz and an automatic game mode ALLM, which quickly reduces input lag upon detecting a console. We manage all of this through a very convenient, purple Game Optimizer menu (Player Panel), which has already become LG's trademark. The manufacturer deserves big credit for consistency regarding HDR. Although the television does not support Dolby Vision in games on Xbox consoles, LG adds a well-implemented HGiG standard. Thanks to this, even on a moderately bright screen, HDR gaming is clear, and details in shadows and highlights are accurately reproduced, rather than "cut off."

The Dreame S100 seems almost like the perfect screen for gamers. The TV is equipped with 2 HDMI 2.1 ports with a bandwidth of 40 Gbps, which means that features such as Auto Low Latency Mode (ALLM) and Variable Refresh Rate (VRR) synchronization in the range of 48-144 Hz work seamlessly on consoles. It also has a well-designed game panel (Game Bar) that allows you to continuously check the most important parameters – from active picture modes to the number of frames rendered by the console, and even the ability to add a crosshair in the center of the screen. All of this looks great on paper, but the biggest issue with the S100 is the implementation of HDR mode in games. The TV does not have a properly implemented HGiG format. As a result, an unsuspecting user may incorrectly configure the console during the initial setup of the display. A wrong configuration can lead to a picture that is too dark or too bright (as a guideline: we suggest setting the brightness in the Xbox console menu to about 600 nits, and in the PS5 to 12 clicks). The Dolby Vision format is also problematic; it often just would not activate at all when using the XBOX – Dreame S100 line. And when it was managed to be activated, gaming was impossible due to a very high input lag that often exceeded 100ms. If the manufacturer can improve the HDR issue in games through an update, the S100 will be truly excellent equipment for gamers. For now, however, one must reckon with compromises.
