TCL V6C vs LG QNED80A6A (IPS)

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.

When it comes to image dynamics and brightness, the QNED80A firmly stands its ground. It is not a “bright beast” – during our measurements, peak luminance oscillated between 350-400 nits. To put it plainly: these values won't allow HDR formats to fully spread their wings. So, do not expect that the glare of the sun or car headlights in films will blind you. However, this television has a powerful ace up its sleeve that salvages the overall picture impression – and that is the colours. LG's engineers have employed an advanced filtration system (technically most likely based on PFS phosphor, marketed as QNED/NanoCell), which does a fantastic job. Thanks to this, despite average brightness, the screen is capable of generating exceptionally saturated and pure hues. Our instruments showed coverage of the wide DCI-P3 cinema colour palette at a level of 93-94%. This is a result that outclasses most standard LCD televisions. In practice, this means that when watching 4K HDR content, the picture – although not very bright – is very plastic, vivid, and delights the eye with its depth of colours.

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.

Here, regardless of whether you encounter the VA or IPS version, the situation is identical. LG engineers once again served us their vision of a "gaming look," which unfortunately has little to do with accuracy. When switched to console mode, the white balance automatically drifts towards very cold regions. The image is dominated by the colour blue, which makes it seem artificially sharpened, and the white is so aggressive that it appears burnt out. This creates an effect we associate with vibrant shop modes – everything is meant to shine and scream "I am digital." While some may appreciate this, we must say plainly: the image is not accurate. If you care about naturalness, we suggest you immediately check the settings and change the colour temperature to a warmer one.

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 professional calibration, the QNED80A in the IPS version has changed unrecognisably, especially with "ordinary" content (SDR). We managed to eliminate the greenish tint and calm down the overly bright gamma. In classic television or older games, colour errors (DeltaE) have dropped below the threshold of perception (value < 2). The picture is now coherent, natural, and truly pleasing to the eye. The situation is somewhat more complicated in HDR mode. Although the colours are now in place, the television has a problem with perfectly controlling the brightness (EOTF curve). Due to the limitations of edge lighting and the rather meagre adjustment options provided by LG in this respect, the television's software at times "does what it wants," just to mask the imperfections of black and contrast. However, this is not a cause for concern – despite these technical limitations, the picture after calibration is a class better than what you saw out of the box.

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 TVs mercilessly expose the flaws of low-resolution materials. Here, it is different. The QNED80A is great equipment for watching content that is not perfect. The processor does a good job of upscaling the image, making even older recordings look quite decent on a 4K screen – they are consistent and free of digital noise. Interestingly, there is a gradation reduction feature available in the settings. It is very effective in combating the so-called banding in low bitrate materials. Of course, it should be approached with some caution. Due to the lower processing power of the chip (compared to the premium series), turning on this option can sometimes result in unwanted artifacts or blurriness. Despite this risk, we encourage experimentation, as in many cases this feature can save a poor-quality viewing experience.

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".

In terms of motion reproduction, the QNED80A unfortunately has a tough time. The television is based on a display with a refresh rate of 60Hz, which is quite a disappointment for the QNED series in 2025. If you are looking for perfect sharpness during dynamic football matches, you may feel somewhat unsatisfied. A solution in this situation is the TruMotion system. It allows for artificial frame generation, which smooths out the image in films and series. In the menu, you will find a De-Judder slider – we recommend setting it to a value of 2, 3, or 4. This is the "golden mean" that improves fluidity without turning the film into a soap opera.

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.

In the gaming section, we won't be pulling the wool over your eyes – the QNED80A is not e-sports equipment. The lack of 120Hz signal support is a fact that must be accepted. However, LG's engineers have done everything possible to maximise the potential of this 60Hz panel, providing gamers with a set of desirable features. First and foremost, the television supports VRR (in the range of 48-60Hz) and ALLM. This means that the image is smooth, not choppy, and the television automatically switches to low-latency mode as soon as we pick up the controller. Accessing these options is incredibly simple thanks to the dedicated system overlay – Game Dashboard. It’s also worth appreciating the support for the HGiG format. This is a nod to owners of modern consoles. Although the screen does not support gaming Dolby Vision, HGiG ensures that the television 'understands' how to display games in HDR. As a result, we avoid the problem of blown-out clouds, which is unfortunately a plague on cheaper LCD televisions.
