TCL C655 / C69B 98' vs LG QNED86A / QNED85A / QNED87A

The quality of the HDR effect on TCL C655 / C69B looks quite promising. The average value in the test charts is around 450 nits, which already allows one to feel the brilliance of light effects and better image dynamics. However, as previously mentioned, this effect can be somewhat dampened by slight differences in bright and dark shades due to the lack of local dimming technology. However, the coverage of the DCI-P3 colour gamut at 94% is commendable, and this is possible thanks to the use of a quantum dot (QLED) panel. As a result, the colours are vivid and well-reproduced when watching HDR content.

Against the backdrop of contrast and black, the brightness of the QNED86A and the overall HDR effect fare much better. It's a television that can achieve around 700 nits under the best conditions, so in terms of luminance alone, there’s nothing to be ashamed of. As a result, scenes with strong lights, explosions, flashes, or bright parts of the landscape – look clear and can make an impression. Interestingly, even in tougher moments with small, contrasting elements on the screen, the television does well with backlighting and details are quite visible. The problem arises when there are many dark tones. The lack of effective local dimming means that black virtually disappears, and instead, we get a grey glow spreading across the entire screen. This kills the depth effect and causes the image to appear flat, as if it lacks cinematic character. In bright animations or family films with vibrant colours, this won't be an issue, as the colours and bright light dominate. But in horror films or productions set in darkness, these limitations are strongly felt. As a consolation, it’s worth noting that the QNED86A is essentially a QLED television with an LED PFS filter, which gives it very good coverage of wide colour gamuts. Both the DCI-P3 palette and the wider BT.2020 perform solidly here. This means that colours in HDR films are saturated, juicy, and have the right depth – even if the black itself is disappointing, the colours can save the viewing experience and make the image look appealing.

The TCL C655 / C69B television offers a film mode that has been tested for colour reproduction quality. Although this mode is called film mode, unfortunately, it has quite a few issues that a director would definitely not want to see when filming their work. Starting with image analysis, it's worth examining the white balance – both in HD and 4K HDR content, the white balance has significant errors. In both cases, the red colour dominates, which makes the colours too warm, and the overall effect takes on a pink or yellow tint. The Colour Checker test confirms these errors – the colour samples veer into incorrect shades, which impacts the overall colour fidelity. A less significant issue is the brightness characteristic. However, it is also not free of flaws. The gamma chart shows a strong spike at the beginning, which can cause the image to be overly bright, and the EOTF curve responsible for brightness in 4K HDR materials also shows considerable fluctuations – it is evident that the television struggles to maintain the appropriate brightness, but it does not always succeed effectively.

We primarily tested the QNED86A in Filmmaker mode, which is designed to provide the most faithful picture. Unfortunately, right out of the box, there were quite a few shortcomings. The most glaring issue was the poorly calibrated white balance – there was a lack of blue, which caused the overall image to take on a slightly yellowish, and sometimes even an orange hue. An even bigger problem was the way the television manages brightness. Due to its technical limitations – that is, local dimming functioning only along the edges of the screen – the QNED86A has a tendency to oversaturate entire scenes. This is where the flattening of the image that we mentioned earlier comes from. Instead of clear depth and contrast, we get something akin to "boosted brightness," which, in the long run, can strain the eyes.

After calibrating the movie mode of the TCL C655 / C69B television, the white balance has been adjusted, and the colours look as they should – confirmed only by slight deviations in the Colour Checker test. The gamma is really accurate, which means the television shouldn’t have issues with brightness in low-resolution materials. Unfortunately, a similar EOTF characteristic is still visible, which is a natural phenomenon in televisions that do not have local dimming – it’s just difficult for them to "shine" brighter in a given part of the screen. Despite this construction limitation that cannot be bypassed, we recommend adjustments in the settings, as the overall colour presentation looks really very good.

What was saved in the QNED86A6A is undoubtedly the colours. After calibration, the white balance was set with great precision, ensuring that deviations on the Colour Checker palette mostly did not exceed the visibility threshold for the human eye. In other words – the colours finally looked natural, without strange yellow or orange tones that had previously marred the perception. Unfortunately, even the best calibration cannot overcome structural limitations. The already mentioned very modest number of local dimming zones and their unfortunate placement meant that the analysis of the EOTF curve in films still showed noticeable scene over-exposures. The image tended to flatten, lacking cinematic depth. Fortunately, this effect is not as visible in older productions or in SDR content. There, calibration really does its job and allows the QNED to be tamed so the image can be pleasing. However, the specifics of this construction – especially the contrast issues – cannot be completely bypassed.

The TCL C655 / C69B TV handles tonal transitions well in lower quality materials. The “Gradual Smoothing” function at its lowest setting effectively eliminates visible banding, but it also results in a loss of detail, for example, in the texture of objects. A plus is that it does not interfere with film grain, allowing the image to maintain a natural look.

In terms of digital processing, the TV adds a significant amount of artificial sharpness, which may appeal to those who prefer a vivid image. For those who prefer a more subtle rendering of details, this may be a drawback. Another downside is the quite aggressive overscan – the image is cropped, which leads to the loss of fragments at the edges and limits the field of view.

If someone is worried about potential "steps" when blending colours, the QNED86A has a simple solution for that. Just turn on the feature called Smooth Gradation and set it to the medium level. Then the TV really smooths out all those unwanted transitions – especially in older productions – and it does so in a way that the film grain doesn’t disappear, nor do any strange artefacts appear. In other words, you can use it without any worries.

The upscaling itself also turns out quite well. Of course, there are no miracles here – with poorer quality sources, you can notice characteristic jagged edges. Fortunately, there is a sharpness slider in the menu, and if someone prefers a more "soft" image, it can be quickly adjusted to their own taste.

Unlike the smaller versions, the 98” model stands out with significantly better motion fluidity. Instead of the standard 60 Hz, this colossal screen is equipped with a full 144 Hz panel, which opens up entirely new possibilities – for both gamers and movie lovers. With its full motion smoother, the television delivers incredible image fluidity, eliminating ghosting and improving the comfort of watching dynamic scenes. It's worth noting that this technology operates across the full refresh rate range, meaning there's no need to compromise between fluidity and quality. Additionally, the "Flicker Reduction" feature allows you to adjust the fluidity to your own preferences – you can choose a more cinematic effect with visible frame rate or a maximally smooth image.

QNED86A has been equipped with a 120 Hz refresh rate panel, so right from the start, it can be said to be suitable for both sports and gaming. And indeed it is – the picture looks smooth, and motion blur isn’t too much of an issue. IPS panels have always had a bit of a problem with this, and here too you can sometimes notice slight blurring, especially in very dynamic scenes, but it’s not something that ruins watching a match or a fast-paced game. For cinema and sports fans, LG has included the traditional TruMotion smoothing feature. In the menu, we have two sliders – one for movies (De-Judder), and the other for sports (De-Blur). The first adds missing frames and allows you to adjust the character of motion – from raw, cinematic to a more fluid, “theatrical” feel. The second improves sharpness during dynamic actions, so it’s worth turning it up a bit if you watch a lot of sports.

The 98-inch TCL C655 / C69B is excellently equipped for gamers. Full-featured HDMI 2.1 ports and a 144 Hz panel allow for gaming in 4K at 120 Hz, providing the smoothness and responsiveness that will impress even the most demanding.

The TV supports variable refresh rate (VRR), eliminating screen tearing, while the automatic low latency mode (ALLM) ensures that gaming starts instantly, without the need for manual adjustment of settings. There is also support for Dolby Vision and HGiG, ensuring that the image quality in games is even better – details are sharp, colours are natural, and contrast is perfectly balanced.

Additionally, the TV offers a dedicated gaming panel that allows for quick adjustment of picture settings without the need to exit the game. It’s a device that meets practically all the requirements of the modern gamer.

When it comes to gaming, the LG QNED86A6A is a complete tool. It features four HDMI 2.1 ports with a full bandwidth of 48 Gb/s, which means that whether you connect a PlayStation 5, an Xbox Series X, or a powerful PC – everything will work in full 4K at 120 Hz with support for all functions. This is a significant advantage, as some competitors still only feature two such ports, which can be troublesome when dealing with multiple devices. It also includes VRR, or variable refresh rate, which eliminates screen tearing, and ALLM, which automatically activates game mode when the console powers on. Dolby Vision Gaming is included as well, alongside proper implementation of the HGiG format, so titles that support these formats look livelier and more detailed. Additionally, there's the Game Optimizer – a kind of control centre for gamers. From this interface, you can view image parameters in real time, quickly switch modes, activate additional features, or adjust picture settings to your own preferences. The LG QNED86A6A has basically everything you would expect from a modern gaming television.
