Hisense A6Q vs TCL C7L

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 TCL C7L is, without doubt, an extremely bright TV. In synthetic tests using static test patterns it can reach peak brightness of around 2800 nits. That's a truly phenomenal result, given the price bracket it occupies. Unfortunately, measurements with real film scenes are not as spectacular as the white-square tests. Brightness in real HDR footage on the C7L falls to around 1200 nits. That's still very good, because the vast majority of modern films are graded to that level. However, when small, pinpoint elements appear on screen, the brightness of those details drops dramatically, even to around 400 nits, which reduces the HDR impact. The TV does this deliberately to preserve black levels and avoid excessive blooming. This is somewhat understandable, but it also shows that Mini LED technology is not completely without compromises in this respect. As for the HDR effect itself, alongside brightness the key factor is, of course, colour. Thanks to the use of new 'super' quantum dots, the colours are simply superb and among the best on the market. The TV is able to achieve very wide coverage of the BT.2020 and DCI-P3 colour gamuts, matching the best RGB Mini-LED screens with ease. Best of all, the C7L can maintain such high colour saturation regardless of the scene being displayed, which is often problematic in competing RGB Mini-LED TVs.

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.

When it comes to out-of-the-box colours, what's new in TCL TVs, including the C7L model, is the addition of a picture mode called Filmmaker Mode. This is significant because such a mode was not previously available from this manufacturer. As the name suggests, this setting is meant to present the picture with the filmmaker's full intent. After our tests we can confirm that it is, without doubt, the best built-in mode on this TV if you want faithful colour reproduction straight out of the box. However, we certainly wouldn't say it's perfect. Like most devices on the market, this C7L also had some factory calibration errors. The white balance in Filmmaker mode drifted towards a slightly greenish-yellow tint, caused mainly by an excess of the green component and a noticeable shortfall in blue. Of course, this won't be a major drawback for the average viewer, but if you care about perfect whites, natural skin tones and getting the full potential out of the structure of those new "super" quantum dots, the TV really needs professional calibration.

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.

After professional calibration we managed to greatly improve the situation in the factory Filmmaker Mode. After our corrections, the errors in the ColorChecker test and across the wide colour gamut fell below the threshold of human perception, that is below a value of 3, which is a very good result. The TCL C7L definitely benefits from such a procedure in terms of colour fidelity, and it's hard to deny. Brightness management for HDR content looks a little worse after calibration, though. As I described earlier, even though we set this model up correctly, when you play real film scenes the TV can handle its brightness in a rather peculiar way. It often brightens some elements on screen contrary to the creator's intent, which is clearly visible in the EOTF traces measured from specific films. Despite this defect, or rather a specific characteristic of the television, one thing you can't fault is that after calibration the C7L was able to reproduce colours accurately.

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.

This can be seen as, to some extent, the Achilles' heel of the C7L. Unfortunately, this TV uses the older MediaTek Pentonic 700 chip, which has never been famed for outstanding digital image processing. You can clearly see that in the behaviour of the progressive smoothing function, the feature responsible for reducing jagged edges and removing digital noise. It simply performs very poorly. When set to low, its effectiveness is almost non-existent. The only small plus is that the algorithm does not further spoil the picture or blur details unnecessarily. Upscaling, that is scaling lower-resolution content to 4K, performs slightly better. It is simply adequate and does not stand out against the competition. There is no denying that the C7L would benefit greatly in this regard if the manufacturer opted for the newer Pentonic 800 processor, which is now appearing in an increasing number of rival models.

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 C7L uses a native 4K panel with a 144 Hz refresh rate, which at lower resolutions when connected to a PC can even reach up to 288 Hz. These are, of course, very high figures and impressive on paper, but bear in mind that almost all the dynamic content you’ll watch on this TV will still run at around a maximum of 120 Hz. To rein in that motion, the TV’s menu includes a motion-smoothing system called "Motion Clarity". It offers several preset modes, including a user mode that we strongly recommend you set manually using our tried-and-tested guides on our YouTube channel. There are two key sliders available. The first, "Blur Reduction", is responsible for cutting motion blur and improving sharpness in dynamic 60-fps material, such as sports broadcasts. The second slider, "Flicker Reduction", lets you add artificial frames to films and series shot in cinematic 24 or 30 frames per second. This, of course, can completely eliminate the irritating judder that appears during camera movement.

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.

When it comes to gaming, the TCL C7L is simply an outstanding TV for players. Thanks to two HDMI 2.1 ports with full 48 Gbps bandwidth, you get access to all the key features required by console owners and powerful PC rigs. There’s a well-working ALLM mode with very low input lag and VRR frame synchronisation that operates over an impressive range from 48 to 288 Hz. Importantly, unlike some rivals, TCL has properly implemented the console HDR10 HGIG profile and supports Dolby Vision in games. The package is completed by a very well designed gamer panel, the Game Bar, which even lets you edit its appearance and change the theme so it perfectly matches the style of your console.

The only thing you can, and even should, criticise is that the TV offers only two full-spec HDMI 2.1 ports, while the other two are older HDMI 2.0. That creates quite a logistical problem. Why? Because one of the fast ports also handles the return audio channel eARC. In practice this means that if you connect a soundbar or home cinema system to the TV, you’ll be left with just one free HDMI 2.1 socket. If you have two consoles at home, or a console and a powerful PC, unfortunately you’ll have to give something up or keep juggling cables at the back of the case while trying to maintain convenient control of the audio system.
