TCL V6C vs LG NANO81A / NANO80A

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

If you're hoping that HDR on the NANO81A will bring tears to your eyes, I have to disappoint you. This TV is just too dark to show what this format is really about. With a brightness of only 250 nits, HDR really only exists on paper here. In practice, during viewing, it's very hard to tell whether we're watching material in high dynamic range or regular SDR – it simply lacks that “punch” of light in the bright parts of the image. But, to balance out the criticism, we do have one light at the end of the tunnel – and quite a distinct one at that. It's about colour gamut coverage. Here, the NanoCell filter shows that it's not just marketing nonsense. Our measurements indicated that the coverage of the DCI-P3 space is around 88%. That's a really solid result, placing this model significantly above typical budget models based on regular white LEDs without any filters. Of course, it still lags a bit behind QLED TVs or advanced panels with PFS filters, but for this price range, the colours are surprisingly saturated and vibrant. It’s just a shame that this low brightness doesn't allow them to fully “spread their wings” with the Nano filter.

We started colour reproduction tests with the Filmmaker mode, which in theory should be the best choice straight 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 graphs, the factory tuning of the V6C is not ideal, although it's not a disaster either. The biggest issue turned out to be a lack of red – the TV clearly "cools" the image, which is especially noticeable on human faces, giving a "zombie skin" effect. This particular issue was the most bothersome during everyday viewing. Looking at the colour palette in HDR content, the shortcomings in red are also noticeable, and their source is the relatively narrow coverage of the colour space. Of course, every TV can be calibrated, so we decided to check how the V6C would perform after such an adjustment.

For every film fan, the natural choice in LG televisions is the Filmmaker Mode. It is designed to show the image as the director intended – without unnecessary "enhancements". Unfortunately, in the case of our test unit NANO81A, the factory settings left a bit to be desired. The main issue turned out to be the white balance. Measurements revealed a distinct deficiency of blue, which in practice meant that many scenes had a slightly yellowish, even "yellowed" tint. The white wasn’t perfectly clean, which took away the freshness of the image. Additionally, the brightness management wasn't perfect either – the factory-set gamma was too low. The image often appeared oversaturated, as if it had been pulled too much from the shadows, which detracted from its naturalness and depth. Fortunately, LG, even in this relatively low price range, does not block access to advanced settings. The calibration options for this model are extensive, which is a significant plus for those who enjoy "fiddling" in the menu. We decided to approach the matter our way and see how much we could squeeze out of this panel with professional calibration.

My dear friends – we haven't faced 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 office. The calibration trials alone took us several hours of work and required a lot of patience. We finally managed to slightly warm up the skin tones, which made faces stop looking like they were pulled straight out of a horror film, a common issue with the factory settings. Unfortunately, that wasn't the end of it – the TV reacted to our adjustments in white balance in a completely unpredictable manner. Where we expected stability in the image in a certain area, new errors appeared, and Color Checker measurements showed deviations that couldn't be rationally explained. It's hard to say whether the fault lay with the software or the design itself, but one thing is certain – the V6C put up exceptionally strong resistance. Ultimately, the calibration brought improvement, especially in SDR content, where the image became more pleasing and natural. However, it must be clearly stated that the design limitations remain. The TV still flattens the image in HDR materials and has noticeable deficiencies in colour reproduction. This is equipment more suited for everyday TV watching or SDR content rather than for cinematic experiences in the highest quality.

After calibration, the NANO81A is a completely different television. What LG offers in terms of image enhancement tools, even in such an affordable model, deserves major credit. We were able to completely eliminate that annoying yellowing of whites and make the colours natural, vibrant, and simply "real". In SDR content (i.e., regular television, YouTube, or older films), the picture now looks miles better – it’s clean, well-balanced, and no longer strains the eyes with strange hues. It’s clear that this panel has significant potential, which is simply wasted out of the box due to poor presets. However, we have one serious reservation that calibration cannot fully overcome – it's about brightness management in HDR mode. The LG algorithm in this model is very conservative. The TV deliberately dims the HDR image to avoid clipping the already weak blacks of the IPS panel. The developers faced a choice: either provide more light and accept that black would become light grey, or dial down the brightness to maintain any contrast. They chose the latter. Despite this, after our adjustments, watching anything on the NANO81 is considerably better.

When it comes to upscaling, the V6C doesn't bring anything groundbreaking to the table. Lower quality content is heavily sharpened, making the image look quite unnatural, at times almost artificial. This can be somewhat alleviated by reducing the sharpness level in the settings, but the effect isn't spectacular. The image still falls short of perfection. The digital processing itself performs better. The function responsible for smoothing tonal transitions works quite effectively, especially at the medium setting, where the image truly appears smoother. Unfortunately, its operation is rather aggressive – it heavily interferes with the overall scene, causing actors in the foreground to start looking like characters from super smooth soap operas. Therefore, we would not recommend using this option if a natural viewing experience is important to us.

It often happens that cheap 4K panels ruthlessly expose all the "dirty laundry" and imperfections in lower resolution materials. However, with the LG NANO81A, the situation is completely different. It's a really solid performer when it comes to handling content that's far from ideal. The built-in processor does a great job with upscaling. Even older recordings look quite decent on this screen – the image is coherent, cleaned of digital noise, and simply pleasant to the eye. A big plus is the gradation reduction feature, which you can find in the settings. It is exceptionally effective in combating colour banding, which is a godsend when watching low bitrate materials, such as from some streaming services or older files from the web. However, it is worth maintaining a certain vigilance. Since we are dealing with a less powerful chip than in LG's top models, too aggressive a setting for this option can sometimes result in minor artifacts or slight blurring of details. Despite this risk, I definitely encourage experimentation with this feature – in many cases, it can save the viewing experience and make low-quality material fully watchable.

Smoothing and motion fluidity are areas where the V6C quickly reveals its limitations. It's a 60 Hz TV, so it was hard to expect miracles here. In dynamic sports scenes, the image performs rather mediocrely. This is most noticeable in darker scenes, where distinct trails and blurred "halos" follow 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 a motion smoother that works while watching movies. Thanks to it, productions filmed at 24 frames per second, which is practically all cinema titles and 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 the full "soap opera effect."

In terms of motion fluidity, the NANO81A unfortunately has a bit of a hurdle. The television is based on a panel with a refresh rate of 60Hz. If you're looking for perfect sharpness in dynamic football matches or fast-paced action games, you might feel somewhat dissatisfied. With such a low native refresh rate, fast objects on the screen will always be a bit blurry.

Even though the V6C is not a TV designed with avid gamers in mind, TCL has included a few features that may appeal to more casual users. You'll not find a 120 Hz panel or HDMI 2.1 ports here, but there is an ALLM mode that automatically switches the TV into low latency mode. There's also a quite practical Game Bar – a simple panel allowing the preview of basic parameters, changing the picture mode, or even enabling a virtual crosshair on the screen. Another interesting feature is the support for Dolby Vision Gaming, intended for Xbox Series S/X consoles – a nice addition, although in practice it doesn’t offer as much as in more expensive models. However, the biggest issue remains the HDR configuration. The HGiG function, responsible for adjusting the brightness and contrast of games to the capabilities of the panel, doesn't respond as we would expect – the picture can be overly dark or too flattened. As a result, a better solution turns out to be simply playing in SDR mode, where the V6C operates steadily and doesn’t try to pretend to be an HDR TV.

NANO81A is unfortunately not a device designed with esports in mind. The lack of 120 Hz signal support is a fact that users planning to purchase this model simply have to accept. Nevertheless, LG’s engineers have worked hard to squeeze the maximum potential from this 60 Hz panel, offering a set of features that genuinely improve gaming comfort. First and foremost, the television supports VRR technology (in the range of 48–60 Hz) and ALLM. This ensures that the image remains stable and does not "tear," and the device automatically switches to low latency mode as soon as it detects a signal from a console. Managing these settings is extremely simple thanks to a dedicated system overlay that allows for a quick preview of parameters without leaving the game. A very significant advantage is support for the HGiG format. This solution is crucial for owners of modern consoles, as it allows the television to correctly "understand" the intentions of game developers regarding HDR tone mapping. In practice, this helps avoid the effect of "blown-out" bright spots, such as clouds or light sources, which is unfortunately a common issue in budget LCD televisions.
