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

Generally speaking, the quality of the HDR effect on the TCL C655 / C69B looks quite promising. The average value in the test charts is around 450 nits, which already allows one to feel the light effects and better image dynamics. However, as previously mentioned, this effect may be partially subdued by slight differences in bright and dark colours, resulting from the lack of local dimming technology. However, the coverage of the DCI-P3 colour palette at 94% deserves high praise, and this is made possible by the use of a quantum dot (QLED) matrix. As a result, colours are vivid and accurately represented when watching HDR content.

The Hisense A6Q is unfortunately difficult to recommend for watching HDR content. The main issues are low brightness and rather modest coverage of a wide colour gamut. The measured brightness of around 300 nits simply isn't sufficient for HDR materials to look impressive. In practice, the picture often resembles standard SDR instead of true HDR with clear differences in brightness and dynamics. Additionally, the colours in such materials do not appear as they should. The television does not utilise additional filters such as QLED or PFS LED, and the coverage of the DCI-P3 colour space at around 80% means that some colours look rather washed out. Consequently, some scenes in HDR materials lose intensity and spectacle, making it difficult to speak of a full HDR experience.

The television TCL C655 / C69B offers a film mode that has been tested for colour reproduction quality. Although this mode is called film mode, it unfortunately has several errors that a director would surely not want to see when recording their work. Starting with image analysis, it is 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, causing the colours to be too warm, and the overall result takes on a 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 veer into incorrect shades, affecting the overall colour fidelity. A less significant issue is the brightness characteristic. However, this is also not without its flaws. The gamma graph shows a strong peak at the beginning, causing the image to be excessively brightened, and the EOTF curve responsible for brightness in 4K HDR material also has substantial fluctuations – it is noticeable how the television tries to maintain the appropriate brightness, but it does not always succeed effectively.

We conducted the tests in the best available mode, namely Filmmaker, however – as is often the case – this does not mean an ideal image 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 a yellowed white, particularly noticeable on large, bright surfaces. This is not due to poor assumptions of the Filmmaker mode itself or the vision of filmmakers, but rather the factory settings requiring adjustment.
Furthermore, looking at the saturation characteristics and the 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 television's film mode TCL C655 / C69B , the white balance has been adjusted, and the colours are presented as they should be – confirmed only by slight deviations in the Colour Checker test. The gamma is really quite accurate, which means the television should not 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 – they simply struggle to "shine" more in a given area of the screen. Despite this inherent limitation that cannot be bypassed, we recommend adjustment in the settings, as the overall colour presentation looks really very good.

The colours after calibration in the Hisense A6Q should be assessed in two ways, as everything depends on the type of content. In the case of SDR material, the effect is truly very good. In everyday programmes, series, and films, it is difficult to spot any serious problems with colours. The yellow tint has been effectively removed, and the television no longer brightens the entire image. As a result, the ColorChecker test showed errors below Delta 2 values, which are already outstanding results, allowing us to speak of very high image quality in standard content. Unfortunately, the situation looks significantly worse in the case of HDR material. 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 the television still generates quite significant colour errors. Certain colours simply cannot be displayed by the screen, making them appear less saturated than they should be. It's a shame because even a simple PFS or QLED filter would significantly improve the final effect. The conclusion is therefore simple – the A6Q is really very well suited for SDR content after calibration, while watching HDR content on it should still be approached with caution.

The television TCL C655 / C69B handles tonal transitions fairly well in low-quality materials. The "Gradual Smoothing" feature at a low setting effectively smooths out tonal transitions; however, it simultaneously blurs significant details, such as the texture of objects. On the plus side, it does not negatively impact the film grain, allowing the natural appearance of the image to be preserved. As for digital processing, the television adds artificial sharpness, which may appeal to some users who prefer a sharpened image. However, for those who prefer a softer look, this could be a disadvantage. A notable downside is that the image has been quite significantly cropped due to what is known as overscan, which reduces the field of view and trims the edges of the image.

Upscaling on the Hisense A6Q works quite decently for a television in this price range. Materials of lower resolution are correctly "upscaled" to a higher one, and the image remains clear without artificial edge enhancement or the typical "over-sharpening" found in cheap models. Unfortunately, the digital processing is significantly worse. In practice, it is difficult to speak of any advanced artifact smoothing or problematic tonal transition masking. In heavily compressed films – especially those from YouTube – the television practically struggles with reducing compression blocks and unwanted banding, making the imperfections in the material clearly visible. The A6Q scales the image well, but when it comes to digital processing, it leaves the user alone with the quality of the source.

The television C655 / C69B is equipped with a 4K@60 Hz panel, which means it works best for watching films and less dynamic content. It also features a "Flicker Reduction" function that allows for the adjustment of image smoothness – the user can choose whether they prefer smoother motion or a more cinematic, frame-by-frame 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 is worth noting that this feature is available in sizes from 55"+. Additionally, the largest variant, 98", is equipped with a 144Hz panel with full motion smoothing.

The motion fluidity of the Hisense A6Q is… well — quite mediocre. It’s a television with a native refresh rate of 60 Hz in 4K, which means that the motion of objects on the screen doesn’t always look perfectly smooth. In dynamic scenes in movies or sports, it’s clear that this isn’t the strongest feature of this model. The situation improves significantly with 1080p content when connecting a console or computer, as the A6Q can operate even at 120 Hz then. This is a big plus, especially for gamers. Nevertheless, the clarity of motion still leaves much to be desired; blurring is noticeable, and the response time of the panel indicates that it is not one of this television’s strong points.

The TCL C655 / C69B television offers nearly the perfect set of features for gamers, supporting all the most important 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 the screen refresh rate to synchronise with the frame rate generated by the console, eliminating screen tearing and providing smoother gameplay.

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

For such an inexpensive television, the Hisense A6Q can truly surprise with what it offers to gamers. It operates in 4K only at 60 Hz, but when a game switches to performance mode and drops to 1080p, the panel can work even at 120 Hz. This is a significant advantage in this price range, as most titles on consoles don't achieve stable 4K at 120 frames per second anyway. In practice, we are realistically playing at 1080p, and here the A6Q provides very enjoyable gaming experiences. On top of that, there are several features 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 there's no need to dig through the entire menu. For such an affordable piece of equipment, it's a really solid set for gamers — perhaps not for the most demanding, but certainly spot on for occasional gaming.
