LG QNED80A6A (VA) vs Dreame S100

Let's now talk about how this television shines. If you are expecting dazzling light effects, we need to temper your enthusiasm. The LG QNED80A is a moderately bright television. Our measurements in most movie scenes indicated values around 350-400 nits. This is not enough to speak of a full, cinematic HDR experience and the sense of that famous "high dynamism" offered by flagship products. However, brightness is not everything. Although the QNED80A is not a "light monster," it makes up for it in another crucial category: colours. This is where PFS technology comes into play, which LG marketers disguise under the name QNED/NanoCell. Thanks to this approach, the television offers a much wider colour palette than classic LCD designs. In our tests, coverage of the cinematic DCI-P3 palette reached a solid 93-94%. What does this mean for you? That even with lower brightness, when watching movies in HDR, colours will be vivid, deep, and appropriately saturated. The image is not washed out but rather juicy, 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 around 600 nits. This is a really good result, although not the highest when considering the competition at this price point. In fullscreen scenes, it is evident that the television can produce an image that impresses with its brightness. Unfortunately, when more complex scenes appeared on the screen, the local dimming algorithm in this model primarily focused on maintaining the deepest blacks. However, this came at the expense of HDR performance – and in a drastic manner. In such scenes, the brightness of bright elements dropped below 100 nits, which is a frankly tragic result, far from any HDR effect. One can improve this aspect, but not without a "however." It is simply necessary to change the local dimming setting in the television's menu, but then the blacks in such scenes simply become grey. It's a pity that Dreame couldn't better refine the local dimming algorithms, and the S100 is another example that the sheer number of local dimming zones does not always translate to a better image. As a consolation, it is worth adding that the Dreame S100 is advertised as a "QLED" type television, although in reality it uses a PFS LED filter. As a result, the colours are appropriately saturated, and the colour gamut coverage of DCI-P3 we measured exceeded 94%.

It might seem that since the QNED80A is one model, regardless of the version, it should offer the same picture. 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 television, “out of the box,” serves us a picture with a clear dominance of red and a deficiency of blue. Overall, it is very warm, even hot. Many users may describe this as a picture that is “too cinematic,” leaning towards sepia. Additionally, there is the issue of the gamma curve – the television has a tendency to slightly artificially brighten scenes (gamma is too low), causing the picture to lose some depth. The good news is that these are not panel errors, but merely software issues. As always in our tests, we conducted professional calibration, which completely eliminated these shortcomings, restoring the natural white balance and correct saturation.

We tested the Dreame S100 in 'movie' mode and we definitely recommend using this setting for watching all types of content. Interestingly, within the deeper settings of the television, we also find a dedicated 'Filmmaker' mode, which is now available from almost every manufacturer. However, in the case of the Dreame S100, we do not recommend using it – it blocks all settings related to the picture and does not allow for any configuration in the menu - even motion smoothing. So, how do the factory colours of the S100 fare? Not too badly, but also not the best. The television itself was quite heavily tinted with blue components, which is clearly visible in our white balance measurements. This made the picture artificially brightened, and the colours had a slight bluish tint. This is confirmed by the Color Checker palette, which showed how the colour samples tend to drift towards blue, generating quite significant colour errors. The picture in HDR mode looked definitely better, where the colour errors were not as prominent, although they still fell far from perfection. Here, the white balance was also shifted too much towards blue, causing considerable errors in colour reproduction.

Was it worth spending time on calibration? Definitely yes. We managed to tame the initial, too warm white balance and, most importantly, correct the gamma curve. The television stopped artificially brightening scenes, which gave the image depth. The greatest improvement is noticeable in SDR content, that is, while watching regular television, YouTube, or playing games without HDR. Here the QNED80A shows its class – colour reproduction errors (DeltaE) have dropped below a value of 2. In technical terms, this means that the errors are virtually unnoticeable to the human eye. The image in everyday use has simply become very attractive, natural, and correct. The difficulties begin with HDR content. Although we managed to improve the white balance, the EOTF curve graph (responsible for brightness at various levels) shows that the television still "interprets" the image in its own way. This stems from the nature of the edge-lit backlight with local dimming and the fact that LG gives the calibrator very little control over this parameter. In short: the television struggles to hide its hardware shortcomings, sometimes ignoring our commands. Nevertheless, the final image is significantly more accurate and pleasant to behold than with factory settings, even if it falls a bit short of studio perfection.

The Dreame S100 has proven to be a device very amenable to professional calibration. In its menu, we found a plethora 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 the excess blue components. The image immediately became much more natural and pleasant to the eye. After fully tuning the colours, the errors in the Color Checker test dropped below Delta E values of 2-3. For the average viewer, this means that any colour distortions have become nearly impossible to perceive with the naked eye. This is truly a pleasant surprise, as new brands in the television market often encounter significant issues with the correct implementation and functioning of sliders in the calibration menu. Here, everything worked as it should. The only thing we must criticise is the way the television manages its brightness in HDR. Due to the specific nature of the local dimming algorithms, anomalies can be seen on the EOTF curve we measured. Where high highlights should appear, there is a slight boosting of the curve above the reference line. In practice, this causes an unnatural brightening of some of the brightest elements in films or games. Despite this minor flaw, professional calibration brings about a huge, very positive change in this model.

In this category, the QNED80A proves to be a true "dark horse." It is an excellent, affordable television for those who frequently watch lower-quality content – for example, traditional cable TV. The processor used here handles upscaling, that is, enhancing low resolution to native 4K, exceptionally well. 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 content. This feature works really effectively, eliminating annoying "banding" of colours under heavy video compression. 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 artefacts or distortions. Nonetheless, it is definitely worth giving this feature a chance, as in most cases the quality improvement is visibly apparent.

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

A separate issue is the phenomenon of overscan (cropping the edges of the frame), which is noticeable here practically all the time. Although there is an option to set the screen to display the full frame in low-resolution materials, this requires activating the previously mentioned Filmmaker mode. And as you know, this mode completely blocks the adjustment of any other sliders in the picture menu. In our test tables, we marked that the television offers an option to disable overscan, as technically such a function exists in the system – however, in everyday use, when maintaining sensible 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 television is equipped with a panel featuring a native refresh rate of 60Hz. There is no denying it – at this price, we expected more as we know that Chinese manufacturers can offer 120Hz screens for a similar price. Due to this parameter, dynamic scenes in sports or fast-paced games are not the strongest aspect of this display. Fortunately, LG has equipped the television with a proven motion smoothing system called TruMotion. It works quite effectively 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: the motion becomes smoother, yet still looks natural, without the artificial "television theatre" effect.

When it comes to motion fluidity, the Dreame S100 performs really well. It features a panel with a refresh rate of 144 Hz, although in reality, the vast majority of people using it in a traditional way will still be limited to 120 Hz (as this is the maximum supported by today's equipment apart from PCs). Thanks to the high refresh rate, the image in motion remains really sharp, largely thanks to the well-functioning MEMC smoother. In the menu, we find predefined modes that allow the television to efficiently generate artificial frames, which effectively improves the fluidity of dynamic sports scenes, but also eliminates image stuttering in film and series materials recorded at 24 frames.

Now that we have established that the QNED80A is a television with a 60Hz panel, we must say it plainly: we will not be playing here at 120 frames per second at any resolution. Does this disqualify the equipment in the eyes of gamers? Not necessarily, especially those "casual" ones. LG has decided to sweeten this technical limitation by packing quite a few useful functions inside. We have support for VRR (variable refresh rate) in the range of 48-60Hz and automatic game mode ALLM, which instantly reduces input lag upon detection of a console. All of this is managed from a very convenient, purple Game Optimizer menu, which has already become LG's hallmark. A big plus goes to the manufacturer 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, playing in HDR is clear, and the details in shadows and highlights are accurately reproduced, rather than "cut off".

The Dreame S100 seems almost like the perfect screen for a gamer. The television is equipped with 2 HDMI 2.1 ports with a bandwidth of 40 Gbps, which means that functions like automatic game mode (ALLM) and variable refresh rate (VRR) ranging from 48 to 144 Hz work seamlessly on consoles. It also features a well-designed gaming panel (Game Bar), allowing users to continuously monitor important parameters—from active picture modes to the number of frames rendered by the console, and even the option to add a crosshair in the middle of the screen. All of this looks great on paper; however, the biggest problem with the S100 is the implementation of HDR mode in games. The television does not have the HGiG format implemented correctly. As a result, an unsuspecting user may incorrectly configure the console when first using the screen. Poor configuration can lead to an image that is too dark or too washed out (as a guideline: we suggest setting the brightness in the Xbox console menu to around 600 nits, and in the PS5 to 12 clicks). The Dolby Vision format also proves problematic, as it often would not activate at all between the XBOX and Dreame S100. And when it was finally managed to be activated, playing was not possible due to a very high input lag often exceeding 100ms. If the manufacturer can improve the HDR issue in games via an update, the S100 will be truly excellent hardware for gamers. For now, however, compromises need to be accepted.
