TCL C655 / C69B (55"-85") vs Hisense A6Q

Overall, the quality of the HDR effect in TCL C655 / C69B looks quite promising. The average value in the test patterns is around 450 nits, which already allows you to feel the light effects and better image dynamics. However, as mentioned earlier, this effect may be somewhat subdued by slight differences in bright and dark shades, resulting from the lack of local dimming technology. However, the DCI-P3 colour gamut coverage of 94% deserves high praise, and this is possible due to the use of a quantum dot (QLED) panel. This makes the colours vibrant and well-reproduced when watching HDR content.

Unfortunately, the Hisense A6Q is hard to recommend for watching HDR content. The main issue remains the low brightness and quite modest coverage of a wide colour gamut. A measured brightness of about 300 nits simply isn't enough for HDR materials to look impressive. In practice, the image often resembles standard SDR rather than true HDR with clear differences in brightness and dynamics. Additionally, colours in such content do not appear as they should. The TV does not utilise additional filters like QLED or PFS LED, and a DCI-P3 coverage of around 80% makes some colours look just too pale. As a result, some scenes in HDR materials lose intensity and spectacle, making it hard to talk about a proper HDR experience.

The TCL C655 / C69B television offers a film mode that has been tested for colour reproduction quality. Although this mode is called film mode, it unfortunately has quite a few errors that the director would certainly not want to see when filming their work. Starting with image analysis, it's worth looking at the white balance – both in HD content and 4K HDR, the white balance has significant issues. In both cases, the red colour dominates, resulting in colours that are too warm, with an overall pink or yellow tint. This can be seen in the image below from the film "Star Wars." The Colour Checker test confirms these errors – the colour samples stray into incorrect shades, affecting the overall colour fidelity. The brightness characteristics are a lesser issue. However, they are not without flaws either. 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 content also has significant fluctuations – it's evident how the television tries to maintain appropriate brightness, but it doesn't always succeed effectively.

We conducted the tests in the best available mode, which is Filmmaker, however – as is often the case – this does not mean the image is perfect straight out of the box. In the case of Hisense A6Q, this mode clearly “swallowed” too much blue in everyday SDR content. In practice, this led to an image with yellowed whites, particularly noticeable on large, bright surfaces. This does not result from poor assumptions of the Filmmaker mode itself or from the vision of filmmakers, but from factory settings that require adjustment.
Additionally, looking at the saturation characteristics and gamma curve in SDR, as well as EOTF in HDR content, there is a slight tendency to brighten most scenes. As a result, the image often appears brighter than it should, losing a bit of its naturalness. For this reason, we decided to perform a professional calibration to restore the proper colour balance and a more accurate brightness characteristic.

After calibrating the movie mode of the television TCL C655 / C69B , the white balance has been adjusted, and the colours look as they should – which is confirmed by only slight deviations in the Colour Checker test. The gamma is really good, which ensures that the television shouldn't have any issues with brightness in low-resolution material. Unfortunately, a similar EOTF characteristic is still noticeable, which is a natural occurrence in televisions that do not have local dimming – they simply struggle to "shine" brighter in a given part of the screen. Despite this design limitation, which cannot be bypassed, we recommend making adjustments in the settings, as the overall colour presentation looks really very good.

Colours after calibration on the Hisense A6Q need to be evaluated in two ways, as everything depends on the type of content. In the case of SDR materials, the effect is really quite good. In daily programs, series, and movies, it’s hard to find any serious issues with colours. The yellow tint has been effectively removed, and the television has also stopped washing out the entire image. As a result, the ColorChecker test showed errors below a Delta 2 value, which are already outstanding results, allowing for a discussion of very high picture quality in standard content. Unfortunately, the situation looks much worse for HDR materials. Yes, the white balance has been corrected and the EOTF curve has been improved, but the limitations of the panel itself remain insurmountable. The lack of support for a wide colour gamut means that the television still generates quite significant colour errors. Parts of the colours simply cannot be displayed by the screen, making them look less saturated than they should. It’s a pity because even a simple PFS or QLED filter would have resulted in a significantly better end effect. The conclusion is therefore simple – for SDR content, the A6Q after calibration works really very well, while viewing HDR content on it should still be approached with caution.

Television TCL C655 / C69B handles tonal transitions in low-quality materials fairly well. The "Gradual Smoothing" feature on low settings effectively smooths out tonal transitions, but it also blurs important details, such as the texture of objects. A positive aspect is that it does not negatively affect film grain, which helps to maintain the natural look of the image. In terms of digital processing, the television adds artificial sharpness, which some users who prefer a sharper image might appreciate. However, for those who prefer a softer look, this may be a drawback. Another downside is that the image has been significantly cropped due to the so-called overscan, which reduces the field of view and cuts off the edges of the image.

Upscaling on the Hisense A6Q works really well for a TV in this price range. Lower resolution materials are correctly “upscaled” to higher resolutions, and the image remains clear without any artificial edge sharpening or the typical "over-sharpening" found in cheap models. Unfortunately, the digital processing is significantly poorer. In practice, it’s hard to talk about any advanced artifact smoothing or masking of problematic tonal transitions. In heavily compressed films—especially those from YouTube—the TV struggles with reducing compression blocks and unwanted banding, making the material's imperfections clearly visible. The A6Q scales the image well, but when it comes to digital processing, it leaves the user alone with the source quality.

The television C655 / C69B is equipped with a 4K@60 Hz panel, which means it's best suited for watching movies and less dynamic content. It also features a "Flicker Reduction" function, allowing users to adjust the smoothness of the image – they can choose whether they prefer smoother motion or a more cinematic, frame-like effect. The television can also adapt to lower resolutions, such as Full HD and 2K at 120 Hz, which will surely please gamers by offering a smoother image at the cost of resolution. It’s worth noting that this feature is available in sizes starting from 55"+. Additionally, the largest variant, 98", is equipped with a 144Hz panel with full motion smoothing.

The fluidity of motion on the Hisense A6Q is... well, quite average. It's a TV with a native refresh rate of 60 Hz in 4K, which means the movement of objects on the screen doesn't always look perfectly smooth. In dynamic scenes in films or sports, it's evident that this is not the strongest point of this model. The situation looks much better with 1080p content when connecting a console or computer, as the A6Q can then operate at up to 120 Hz. That's a big plus, especially for gamers. However, the sharpness of motion still leaves a lot to be desired, with noticeable ghosting, and the response time of the panel shows that it isn't one of the TV's strong suits.

The TCL C655 / C69B TV offers an almost perfect set of features for gamers, supporting all the key technologies. It has an ALLM feature that automatically switches the TV to low latency mode, significantly improving responsiveness and minimising signal lag, which is especially important during dynamic gameplay. The VRR feature allows synchronisation of the screen refresh rate with the number of frames generated by the console, eliminating screen tearing and providing smoother gameplay.

The TV also supports Dolby Vision in gaming mode, ensuring better colour and contrast reproduction in games that support this format, and the Game Bar enables quick access to gameplay-related settings, such as response time, latency level, and other parameters. Unfortunately, the C655 / C69B does not support 4K resolution at 120 Hz (the 98" variant is the exception), which may be disappointing for more demanding gamers seeking the ultimate smoothness in high-resolution games. However, if we can forgo 4K, the TV offers support for Full HD and 2K at 120 Hz, providing a smoother image and serving as a great alternative for those who prefer higher refresh rates at the expense of resolution.

For such an inexpensive television, the Hisense A6Q really can surprise with what it offers gamers. It operates in 4K only at 60 Hz, but when the game switches to performance mode and drops to 1080p, the panel can work at even 120 Hz. In this price range, that's a big plus, as most titles on consoles don’t deliver a stable 4K at 120 frames. In practice, we are realistically gaming in 1080p, and here the A6Q provides a very enjoyable gaming experience. Additionally, it has a few features that are usually found in more expensive models: ALLM, VRR, and Dolby Vision Gaming for Xbox Series X/S. Everything is gathered in one place, in a simple and convenient Game Bar, so you don't need to dig through the entire menu. For such an affordable piece of equipment, it's really a solid setup for gamers — maybe not for the most demanding, but definitely spot on for occasional gaming.
