TCL V6C vs LG NANO81A / NANO80A

When it comes to HDR, the TCK V6C clearly shows that this is not its strong suit. A peak brightness of around 200 nits makes it difficult to speak of true HDR effects – the image simply remains too dark to extract details in bright scenes or convey the appropriate dynamics. Although the television formally supports many HDR formats, in practice it is not equipped for such demanding content. The lack of additional coatings that enhance colours, such as QLED or PFS LED, further limits the attractiveness of the image – in more spectacular productions, colours can appear 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 cinematic experiences in high quality.

If you are counting on HDR in the NANO81A to bring tears to your eyes, I must disappoint you. This television is simply too dark to truly show what this format is all about. With a brightness of only 250 nits, HDR exists here mainly on paper. In practice, during viewing, it is very difficult to distinguish whether we are watching high dynamic range content or regular SDR – it simply lacks that ‘punch’ of light in the bright parts of the image. However, to give credit where it’s due, we do have a glimmer of hope here – and quite a clear one at that. It concerns the colour gamut coverage. Here, the NanoCell filter shows that it is not just marketing nonsense. Our measurements indicated that the coverage of the DCI-P3 space is around 88%. This is a really solid result that places this model significantly higher than typical budget options based on standard white LEDs without any filters. Of course, it still falls short of the level of quantum dot (QLED) TVs or advanced panels with PFS filters, but for this price point, the colours are surprisingly saturated and vibrant. It's just a shame that this low brightness prevents them from fully ‘spreading their wings’ with the Nano filter.

We started our 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 significantly alter the image and spoil its natural character. As you can see from the graphs, the factory calibration of the V6C is not ideal, although it's not a complete disaster either. The biggest issue turned out to be a deficiency in 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 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 television 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. Its aim is to display images as the director intended – without unnecessary "enhancements". Unfortunately, in the case of our test unit NANO81A, the factory settings left something to be desired. The main issue turned out to be the white balance. Measurements showed a distinct deficiency of blue colour, which in practice meant that many scenes had a slightly yellowish, even "yellowed" tint. The white was not perfectly pure, which detracted from the freshness of the image. Additionally, brightness management was also not ideal – the factory-set gamma was too low. The picture often appeared oversaturated, as if overly lifted from the shadows, which caused it to lose naturalness and depth. Fortunately, LG, even in this relatively low price category, does not block access to advanced settings. The calibration possibilities of this model are enormous, which is a big plus for those who enjoy "digging" in the menu. We decided to approach the topic in our own way and see how much we could squeeze out of this panel with professional calibration.

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 televisions we have encountered in the editorial office. The calibration attempts alone took us several man-hours and required considerable patience. We finally managed to slightly warm the skin tones, which made faces stop looking like they were pulled straight from a horror film, a complaint regarding the factory settings. Unfortunately, that's not the end of it – the television reacted to our white balance corrections in a completely unpredictable manner. Where we expected stabilisation of the image in a certain area, new errors appeared, and the Color Checker measurements showed deviations that could not be rationally explained. It is hard to determine whether the issue 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 pleasant and natural. However, it must be clearly stated that the design limitations remain. The television still flattens the image in HDR materials and has noticeable deficiencies in colour reproduction. This device is rather intended for everyday television watching or SDR materials than for cinematic viewing 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 a big plus. We managed to completely eliminate that annoying yellowing of whites and make the colours natural, vibrant, and simply "true". In SDR content (that is, regular television, YouTube, or older films), the picture now looks worlds better – it is clear, well-balanced, and no longer strains the eyes with strange hues. It is clear that this panel has significant potential, which is simply wasted by poor presets out of the box. However, we do have one serious reservation that calibration cannot fully overcome – it concerns brightness management in HDR mode. LG's algorithm in this model is constructed very conservatively. The television intentionally dims the HDR picture to avoid overexposing the already weak blacks of the IPS panel. The programmers faced a choice: either to provide more light and accept that the blacks would become light grey or to reduce the brightness to maintain any contrast. They chose the latter. Nevertheless, after our adjustments, watching anything on the NANO81 is significantly better.

When it comes to upscaling, the V6C does not bring anything groundbreaking to the table. Lower quality content is heavily sharpened, making the image look very unnatural, at times even artificial. This can be somewhat 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 does indeed appear smoother. Unfortunately, its operation is rather aggressive – it heavily interferes with the overall scene, causing the actors in the foreground to start looking like characters from super smooth soap operas. Therefore, we would rather not recommend using this option if a natural viewing experience is important to us.

It often happens that cheap 4K panels mercilessly bring to light all the "dirt" and imperfections of lower-resolution content. However, with the LG NANO81A, the situation is quite different. This is truly a solid performer when it comes to handling content that is 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 significant advantage is the gradation reduction feature that you will find in the settings. It is extraordinarily effective in combating colour banding, which is a lifesaver when watching materials with a low bitrate, for instance, from some streaming services or older files from the web. However, it is worth maintaining a certain level of caution. Since we are dealing with a less powerful chip than in LG's top models, setting this option too aggressively may sometimes result in minor artefacts or slight blurring of details. Despite this risk, I definitely encourage experimenting with this feature - in many cases, it can save the viewing experience and make low-quality material fully watchable.

Motion smoothing and fluidity are areas where the V6C quickly reveals its limitations. It's a 60 Hz television, so it was difficult to expect miracles here. During dynamic sports scenes, the image is rather average. This is most noticeable in darker scenes, where clear trails and blurred "glows" follow moving objects, which can be quite distracting. This is definitely a weaker point of this design. Fortunately, there is also a small plus. The V6C is equipped with a motion smoother that works while watching films. Thanks to it, productions recorded at 24 frames per second, which includes practically all cinematic titles and series, can look smoother than they were actually recorded. Importantly, the intensity of the effect can be adjusted to personal preferences – from a slight smoothing to a full "soap opera effect".

When it comes to motion fluidity, the NANO81A unfortunately has a hard time. The television is based on a panel with a refresh rate of 60 Hz. If you are looking for perfect sharpness in dynamic football matches or fast action games, you may feel a bit disappointed. With such a low native refresh rate, fast objects on the screen will always be a little blurred.

Although the V6C is not a television designed with avid gamers in mind, TCL has added a few features that might appeal to more casual users. It does not have a 120 Hz panel or HDMI 2.1 ports, but there is an ALLM mode that automatically switches the television to low-latency mode. Additionally, there is quite a practical Game Bar – a simple panel for previewing basic parameters, changing picture modes, or even activating a virtual crosshair on the screen. An interesting feature is the support for Dolby Vision Gaming, intended for Xbox Series S/X consoles – a nice addition, although in practice it does not offer as much as in more expensive models. However, the biggest issue remains the configuration of HDR. The HGiG function, responsible for adjusting the brightness and contrast of games to the capabilities of the panel, does not respond as we would expect – the image can be excessively dark or too flat. As a result, the better solution turns out to be simply playing in SDR mode, where the V6C performs stably and does not try to pretend to be a HDR television.

NANO81A is unfortunately not hardware designed for e-sports. The lack of support for a 120 Hz signal is a fact that users planning to purchase this model simply have to come to terms with. Nevertheless, LG's engineers have made an effort to maximise the potential of this 60 Hz panel, offering a set of features that genuinely enhance the gaming experience. Firstly, the television supports VRR technology (within the range of 48-60 Hz) and ALLM. As a result, 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, which allows for quick viewing of parameters without leaving the game. A very significant advantage is the support for the HGiG format. This solution is crucial for owners of modern consoles because it enables 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.
