TCL V6C vs Dreame S100

When it comes to HDR, the TCK V6C clearly shows that it is not its strong suit. Peak brightness around 200 nits makes it difficult to talk about true HDR effects – the image simply remains too dark to extract details in bright scenes or convey the appropriate dynamics. Although the TV formally supports many HDR formats, in practice it is not adapted for such demanding content. The lack of additional coatings that enhance colors, such as QLED or PFS LED, further limits the appeal of the image – in more spectacular productions, colors may seem washed out compared to more expensive models. Therefore, the V6C will primarily serve as a television for everyday TV, YouTube, or SDR materials, rather than as equipment for high-quality cinematic experiences.

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.

We started the color reproduction tests with the Filmmaker mode, which in theory should be the best choice right after taking the television out of the box. It certainly performs better than the Eco or Dynamic modes, which heavily interfere with the image and spoil its natural character. As you can see in the charts, the factory tuning of the V6C is not ideal, although it’s not a disaster either. The biggest problem turned out to be a lack of red – the television clearly "cools" the image, which is particularly noticeable on human faces, giving a "corpse skin" effect. This issue was the most bothersome in daily viewing. Looking at the color palette in HDR content, the deficiencies in red are also noticeable, and their source is the relatively narrow coverage of the color space. Of course, every television can be calibrated, so we decided to check how the V6C would perform after such an adjustment.

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.

My dear friends – we haven't had such a difficult "calibration battle" in years. The V6C turned out to be one of the most stubborn TVs we've dealt with in the editorial office. The calibration trials alone took us several working hours and required a lot of patience. We finally managed to slightly warm up the skin tones, which made the faces stop looking like they were straight out of a horror film, a flaw in the factory settings. Unfortunately, that's not the end of it – the TV reacted to our adjustments in white balance in a completely unpredictable way. Where we expected image stabilization in a given area, new errors appeared, and the Color Checker measurements showed deviations that couldn't be rationally explained. It's hard to say whether the software or the construction itself was to blame, but one thing is certain – the V6C offered exceptionally strong resistance. In the end, the calibration brought improvement, especially in SDR content, where the image became more pleasant and natural. However, it must be clearly stated that the design limitations remained. The TV still flattens the image in HDR material and has significant deficiencies in color reproduction. This is equipment rather intended for everyday TV watching or SDR materials than for cinematic screenings in the highest quality.

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.

When it comes to upscaling, the V6C does not bring anything groundbreaking. Lower quality content is heavily sharpened, making the image look very unnatural, sometimes even artificially. This can be partially mitigated by lowering the sharpness level in the settings, but the effect is not spectacular. The image still remains far from ideal. The digital processing itself performs better. The function responsible for smoothing tonal transitions works quite effectively, especially at the medium setting, where the image indeed appears smoother. Unfortunately, its operation is quite aggressive – it heavily interferes with the overall scene, causing the actors in the foreground to start looking like characters from super smooth telenovelas. Therefore, we would not recommend using this option if natural reception of the image is important to us.

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.

Motion smoothing and motion fluidity is an area where the V6C quickly reveals its limitations. It is a 60 Hz TV, so it was hard to expect miracles here. In dynamic sports scenes, the picture comes off rather average. This is most noticeable in darker scenes, where clear smears and blurry "halos" trail behind moving objects, which can be quite distracting. This is definitely a weaker point of this model. Fortunately, there is also a small plus. The V6C is equipped with motion interpolation, which works while watching movies. Thanks to it, productions recorded at 24 frames per second, meaning practically all cinematic titles as well as series, can look smoother than they were actually recorded. Importantly, the intensity of the effect can be adjusted to personal preferences – from slight smoothing to full "soap opera 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.

Although the V6C is not a television designed with avid gamers in mind, TCL has included a few features that may appeal to more casual users. There is no 120 Hz panel or HDMI 2.1 ports, but there is an ALLM mode that automatically switches the TV to low-latency mode. Additionally, there is a quite practical Game Bar – a simple panel that allows you to view basic parameters, change the picture mode, or even enable a virtual crosshair on the screen. An interesting feature is also the support for Dolby Vision Gaming, intended for Xbox Series S/X consoles – a nice addition, though in practice it doesn't offer as much as in more expensive models. However, the biggest problem remains HDR configuration. The HGiG feature, which adjusts the brightness and contrast of games to the panel's capabilities, does not respond as we would expect – the image can end up being overly dark or too flat. As a result, a better solution turns out to be simply playing in SDR mode, where the V6C performs stably and does not try to pretend to be an HDR TV.

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.
