Hisense E7Q PRO / E79Q PRO vs TCL C8L / QM8L

When it comes to HDR effect quality, the E7Q PRO unfortunately is not a television that impresses with brightness alone. In real film materials, we measured around 250–300 nits, which is simply not enough for HDR to look spectacular. There's a lack of that "spark" in bright details, flashes, and light effects, and in many HDR scenes, it can resemble more of a good SDR than true cinematic HDR. The silver lining in all this is the colours. We managed to confirm that the E7Q PRO is a PFS type television, which means it has an additional filter that improves colour gamut coverage. Because of this, even if the brightness doesn't deliver, the colours in HDR content can be properly saturated and pleasing to the eye, without the impression of a "washed-out" image.

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.

In terms of colour reproduction, we tested the Hisense E7Q Pro in Movie mode, which undoubtedly turned out to be the best built-in preset. It is this mode, unlike the Eco, Standard, or Dynamic settings, that offers the most natural colours straight out of the box. While no factory mode is completely free of flaws, the E7Q Pro deserves high praise for its colour rendition in standard SDR content. The colour palette has been very well tuned, and errors in the Color Checker tests often did not exceed a value of 3, which is an outstanding result rarely seen in such affordable TVs. The only drawback we noted in SDR is the tendency to darken certain elements of the image, as indicated by a slightly raised gamma curve. The TV performs slightly worse with colours in HDR mode. Here, colour errors become noticeable to the naked eye, mainly due to a deficiency of blue in the white balance. This causes the colours on screen to appear too warm, and for some viewers, they may seem almost "too cinematic." Of course, to improve these parameters, we proceeded with professional calibration.

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.

In the case of materials with standard dynamic range (SDR), our actions in Filmmaker mode turned out to be largely cosmetic 😉. We mainly focused on a subtle adjustment of the white balance and equalising the gamma curve, which allowed us to recover details in the darker areas of the image that previously tended to get lost. However, it's worth noting that the E7Q Pro unit we tested happened to be exceptionally well-made from the factory. We remind you that these parameters depend on the specific unit – with mass production, factory calibration can be random, so your unit may require slightly different adjustments. The biggest beneficiary of professional calibration was undoubtedly HDR mode. This is where we did the most work, which brought spectacular results. We successfully tamed the excessive warmth of the image, caused by a factory shortfall in blue colour. After calibration, colour errors were reduced to a significantly lower level, which will certainly please those watching a lot of streaming content in HDR format, expecting faithful reproduction.

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.

When it comes to upscaling and digital image processing, the E7Q PRO deserves praise. The scaling performs really well here and doesn't fall dramatically short of much more expensive, advanced TVs. Lower quality materials can look clear and reasonable, without the impression that the image is artificially "overdrawn." The smoothing function, however, presents a bit worse. Yes, it can be effective and improve tonal transitions in low-quality materials, but at the same time, it can introduce unwanted effects. Sometimes it removes film grain or adds unwanted artifacts, giving the image a more "digital" character. Therefore, we mainly recommend it to those who prefer a smoother, less cinematic image style.

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.

In the category of motion blur and fluidity, the E7Q PRO has one very strong argument. At this price, Hisense has added a 120 Hz panel, and in PC mode, it can even operate at 144 Hz. This immediately provides greater possibilities in motion settings, as more options for smoothing the image appear in the menu. Among other things, we have frame interpolation options, allowing us to adjust the fluidity for sports or movies, depending on whether we prefer a more cinematic character or a "theatrical" smoothness.

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.

E7Q PRO is a phenomenal screen for gamers. Besides the typical "issue" with Hisense, which is the lack of support for the HGiG format due to constantly active tone mapping, we get practically everything one could expect from a TV that is supposed to have a gaming tag. There are two HDMI 2.1 ports, along with a full set of key features. We have variable refresh rate, automatic switching to game mode, and support for 4K at 120 Hz. On top of that, all the important settings are at hand in the clear Game Bar. This tool not only looks modern, but it also has a typically "gaming" edge and actually makes life easier while 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.
