Hisense A6Q vs TCL C8L / QM8L

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.

When it comes to HDR, the TCL C8L turns out to be a hellishly bright television – and I mean that literally. On a synthetic test pattern of 5%, our measuring equipment indicated a result exceeding 4500 nits. That's an almost cosmic result, considering that reference director's monitors, which we often refer to in our materials, usually operate around 4000 nits. Does this mean the C8L breaks barriers and climbs to the technological peak of Mini-LED? Not quite. Dry synthetic tests are one thing, and real film images are another. In real, varied scenes, the C8L hits around 1600 nits at its peak. That's still a very good result, ensuring a very high level of HDR dynamics, but it's clearly lower than what the manufacturer boasts in the specifications. The trouble begins with very small bursts of light – then the brightness can drastically drop to around 600 nits. The algorithm does everything it can to maintain deep blacks and minimise halo effect, but it does so at the cost of HDR impact. This is ideal evidence that laboratory test patterns rarely correlate with what we ultimately see on the screen.

Huge applause is due for colour reproduction, all thanks to the new generation of SQD (Super Quantum Dot) quantum dots. The coverage of the DCI-P3 palette reaches 97%, but the jaw-dropping measurements come from the notoriously demanding BT.2020 space. The C8L achieves an impressive 90% in this area, placing it alongside today’s top screens that feature RGB backlighting. Importantly, unlike some screens with Micro/Mini RGB backlighting, this effect is stable regardless of the scene being displayed. Of course, it’s important to remember that content mastered for such a wide gamut in films or series is still a rarity. However, the very fact that the panel has such a "reserve of colours" deserves huge admiration.

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.

We tested the TCL C8L in the best factory mode available in the TV's menu for picture fidelity. I’m of course talking about Filmmaker Mode, which was introduced into this brand’s software relatively recently (a year ago in the K series). Thanks to it, the average user can get pretty good colour reproduction straight out of the box, although it’s certainly not perfectly tuned. Looking at the factory white balance of our unit, in both SDR and HDR content, there was a clear lack of the red component, which made the picture noticeably cooler and slightly shifted towards bluish‑green hues. The issue of brightness management is also ambiguous, as we mentioned earlier. While in SDR content the linearity of the gamma parameter is really good and consistently holds the reference value of 2.4, things are much worse in HDR. Tracking the EOTF curve clearly shows the TV’s brightness is considerably boosted across the range, which can make the final image overly bright and inconsistent with the creators’ intent, and that is in a mode that by definition should avoid this. Of course, like every unit in our lab, this one was also subjected to professional calibration, and you can find the results below.

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.

As you can see, the results of a professional calibration of the TCL C8L are genuinely promising, thanks to the extensive adjustment tools the manufacturer made available in the menu. Most importantly, we were able to fully correct the white balance, eliminating a lack of red so the image finally stopped drifting into unwanted, cool tones. After this step, errors in the ColorChecker test fell to near-reference values, regularly sitting below a Delta E threshold of 2, which is under the level noticeable to the human eye.

Since the test patterns look so perfect, you might ask: why then the lower final score in this category? The answer lies in the brightness management discussed earlier. Although the menu includes sliders that let you precisely straighten the EOTF curve on synthetic signals, when confronted with real film material (I recommend turning the EOTF filter on when watching films), it becomes clear that the TV in most scenarios still responds to HDR metadata in its own way. As a result, the image can be a touch too bright and not in line with the creators' intent, and it was precisely for this lack of repeatability with real-world films that we had to dock the C8L a few points.

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.

This year the C8 series and the higher-end models have probably received the biggest and most eagerly awaited upgrade in TCL's history, and it's to do with digital image processing. The C8L is the entry-level model in the manufacturer's line-up to be fitted with the latest flagship MediaTek Pentonic 800 chipset (shown in the menu as MT9655). It is thanks to its processing power that the feature called "Gradual Smoothing" finally works the way it should. The algorithm effectively removes unwanted posterization (ugly tonal transitions / colour banding) from the picture, doing so intelligently enough that it does not degrade the sharpness of other details.

The processor also handles upscaling lower-resolution content to 4K very well. Although judging this element can be purely academic, because the differences between today's TVs in this class are very subtle. The most important point is that TCL finally has nothing to be ashamed of compared with the competition.

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 C8L is equipped with a fast panel with a native 144 Hz refresh rate. That spec will be most appreciated by demanding PC gamers, while most users, relying on consoles or TV broadcasts, will use a steady 120 Hz. And it is at 120 Hz that the motion-processing algorithms take care of image processing for films, series and sports. In the TV's menu you'll find a "Motion Clarity" option that lets you customise the motion smoothing to your preferences. The algorithms handle both cinematic productions at 24 or 30 frames per second and fast-paced sports broadcasts at 50 or 60 frames per second, maintaining the right level of smoothness.

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.

For gamers – especially for owners of powerful PCs and multiple consoles simultaneously – the TCL C8L is a true beast. This is the first model in this manufacturer's lineup that is equipped with four full HDMI 2.1 ports with a maximum bandwidth of 48 Gbps. This is directly due to the use of the new Pentonic 800 processor, which we've mentioned before. Additionally, the TV seamlessly supports practically every gaming feature. It has an automatic game mode (ALLM) that reduces latency to minimal levels, as well as full variable refresh rate (VRR) operating in an impressive range of up to 288 Hz. It also supports standards such as G-Sync and FreeSync from Nvidia and AMD. When it comes to image display standards, there are no compromises either: the C8L offers complete support for HDR formats in gaming, including gaming Dolby Vision and the HGiG profile. We can conveniently manage all these features from a very readable gamer bar (Game Bar), which we can customise according to our own preferences. From a purely gaming perspective, the C8L really has no flaws – well, maybe apart from the previously mentioned slight ghosting. But other than that? It’s a no-nonsense machine for gamers.
