TCL C75B vs Hisense E7Q / E79Q

During our luminance test, the TCL C75B "spat out" about 380 nits of brightness. We recorded similar results while watching most of the films we tested. These can be considered average – the television does not perform badly in this segment, but around 400 nits is definitely too low to fully experience the magic of HDR effects. Of course, such results are better than those of budget models, which can achieve nearly half as low brightness values. However, for HDR enthusiasts seeking stronger light effects and greater realism, the C75B may prove insufficient. On the plus side, it's worth mentioning the 95% coverage of the DCI-P3 color palette. This is a very good result that easily suffices to enjoy a wide range of colors in content available on popular streaming platforms. Vivid and rich colors are definitely a strong point of this model.

Hisense E7Q / E79Q is a television with average brightness, whose peak luminance level is around 350-380 nits. This is an absolute minimum that allows for watching HDR content in a way that is close to the creators' intentions, although without a clear "wow" effect. The results of synthetic tests on white images have been confirmed in practice – in movie scenes, the bright parts of the image are stable and fairly uniform, but it is hard to speak of a true "lighting impact" here. In everyday use, for example, while watching Netflix or YouTube, the HDR effect is acceptable and is completely sufficient for most users. However, it must be stated clearly – this is not the level of top screens, and one should not expect that at this price point. Fortunately, the Hisense E7Q / E79Q has an advantage that allows it to gain quite a few points: it is a PFS LED QLED panel, utilizing an additional phosphor layer that improves color reproduction. The measured range of the DCI-P3 palette is around 92%, which means that the colors in most scenes are vibrant, well-saturated, and pleasing to the eye, especially for this price range.

TCL C75B offers many picture modes, but in our opinion, the best choice is the "Film" mode. Although its settings are quite good, the television struggles with certain color reproduction issues. In tests, we noticed that the image had a noticeably pinkish tint compared to what could be considered correct. This effect was particularly noticeable in skin tones, which appeared unnaturally warm. The main culprit of this phenomenon turned out to be the white balance, characterized by an excessive amount of blue and red in both HD and 4K HDR materials.

Another issue was the way brightness was reproduced. The gamma, which is responsible for the visibility of details in darker materials, was definitely boosted, causing details in the darkest parts of the screen to be invisible, lost in total blackness (e.g., the bottom part of the screen in the comparative photo - the area around the actress's ear). Similarly, the situation was reflected in the EOTF curve, which was below the correct value, suggesting that a similar problem may be encountered in 4K HDR content.

Thanks to our experience and the appropriate tools, we decided to take matters into our own hands and see how much could be extracted from this model after professional calibration. Details are described in the next section.

In Filmmaker mode, the Hisense E7Q / E79Q television was able to really surprise positively. Even after the first measurements, it turned out that the white balance is quite well calibrated, and the only minor deviation was a slight tendency toward a purple hue, which we mentioned earlier. However, this did not significantly affect the overall character of the image – it remained coherent and pleasant to perceive. A much larger problem turned out to be the brightness characteristics (gamma) in SDR content and the EOTF curve in HDR films. The television clearly brightened the image, flattening the contrast and taking away its depth. Gamma values could drop from the reference 2.4 down to about 1.9, making the image appear as if it were covered with a thin, milky layer. Fortunately, this is a problem that can be relatively easily corrected through calibration.

After calibrating the TCL C75B, it has clearly improved in terms of color reproduction. Although the TV does not offer many options for adjusting the white balance, we were able to refine its settings significantly. As a result, the image has stopped being overly pink, and the colors now look much more natural and harmonious.

The gamma jump, which was previously a problem, has not disappeared completely, but we managed to significantly reduce it. This has made the details in dark scenes more visible – both in HD and 4K HDR material.

Unfortunately, the lack of local dimming is still noticeable. The "glowing black" effect remains, but that's a limitation of the display itself. Despite this, the colors after calibration look vastly better, and the image is much more enjoyable to watch.

The biggest beneficiary of calibration for the Hisense E7Q / E79Q turned out to be the SDR mode without a doubt. It managed to achieve nearly perfect picture quality – most errors in the Color Checker test dropped below a value of 3, and often even below 2, which is a remarkable result for this class of equipment. The greatest improvement came from aligning the brightness characteristic (gamma), making the picture no longer look washed out and regaining its natural depth. In HDR content, colors were also improved, and the purple tint we mentioned earlier was eliminated, but errors in the Color Checker measurements were still noticeable. This is due to the fact that – as is often the case with Hisense televisions – the screen manipulates brightness quite strongly, oversaturating some colors. This was also indicated by the EOTF curve, which was slightly above the reference values, suggesting these minor problems with excessive brightening. Despite this flaw and the construction limitations that arise with HDR content, the Hisense E7Q / E79Q gained a lot after calibration. In everyday use, the television presents a cohesive, natural, and pleasant-to-the-eye picture, and the difference compared to factory settings is truly vast.

The TCL C75B has a tonal transition smoothing feature, but unfortunately, we can't praise it. Regardless of the selected level – low or high – tonal transitions in older materials remained visible, as if the feature didn't work at all. It's hard to say something positive about it because, in practice, it seems completely useless.

The image scaling is better. The TV performs quite decently, although on thinner elements, like branches in the background, you can notice slight halos. However, this is not something that significantly interferes with daily viewing.

Unfortunately, a bigger problem turned out to be overscan, which is the trimming of the image edges. In our tests, it happened that news tickers or other elements close to the edge of the screen were cut off. This is definitely something worth paying attention to, especially if we use the TV for watching news programs or content with text on the screen.

In the case of Hisense E7Q / E79Q, upscaling and digital image processing are not the strongest features of this television. It is clear that the manufacturer opted for simplicity rather than advanced image processing algorithms. The television does not offer any functions for smoothing tonal transitions or systems for improving image clarity, which means that lower resolution materials simply look very raw. On the screen, subtle compression edges can be noticed, which better processors in other models can effectively hide.

During tests of HD materials, we noticed that the E7Q tries to artificially enhance detail, which sometimes works and sometimes has the opposite effect – the image becomes soft, slightly smeared, at times even "watery." There is no aggressive sharpening that ruins naturalness, but there is also no finesse in detailing that better image processors offer.

TCL C75B definitely has something to offer gamers. The TV is equipped with a panel that can display images with a refresh rate of 144 Hz in 4K, and even 240 Hz in Full HD. These are really great results, especially for a model from the budget range.

Additionally, there are features for improving smoothness and reducing motion blur in films. The "Motion" option allows for precise adjustment of the effect on a 10-step scale, providing a lot of customization options – everyone can set the smoothness to their liking.

Hisense E7Q / E79Q is a television with a 60 Hz screen, so 4K sports fans may feel a slight disappointment – we simply won't see such smooth images here as in more expensive models with higher refresh rates. Fortunately, when it comes to movies, the situation is much better. Cinematic materials recorded at 24 frames per second can be displayed here using a motion smoothing feature, allowing the user to adjust the image to their preferences – more cinematic with a visible frame or smoother, in a theatrical style.

The TCL C75B is undoubtedly a television designed for gamers. It offers almost everything that the most demanding console users need. With the implementation of full-bandwidth HDMI 2.1, the television supports features such as ALLM (automatic low latency mode) and VRR (variable refresh rate) – operating across the full capabilities of the TV, up to 240 Hz in Full HD resolution.

Additionally, the television supports advanced HDR technologies, including Dolby Vision and HGiG, which allows for even better detail representation in HDR-optimized games. The C75B is also equipped with a very convenient interface for gamers in the form of a Game Bar, where you can check all key parameters, such as refresh rate, input lag, or picture settings – all within one click's reach.

In a nutshell: the C75B is an excellent choice for gamers, offering a wide range of features that allow for fully enjoying the capabilities of modern consoles and games.

Hisense E7Q / E79Q is truly a successful television for gamers, even though it doesn't support 4K signal at 120 Hz. However, the manufacturer has included a set of features that until recently could only be found in more expensive models. There is ALLM, or automatic switching to low-latency mode, which allows the television to activate game mode with very low input lag. We also have VRR, functioning up to 60 Hz – this may not seem impressive on paper, but in practice, it is fully sufficient, as most games on consoles do not exceed this limit. All these settings can be quickly found in the Game Bar panel, a convenient menu created specifically for gamers. From this level, you can change picture modes, turn on a frame rate counter, or even… a crosshair on the screen – in the Vidaa system humorously named "target point," which is a result of awkward translation by the Chinese manufacturer.

Particularly praiseworthy is the ability to play in 1080p at 120 Hz, which realistically improves the smoothness and responsiveness of the image. This way, if someone wants to play a few titles at a higher refresh rate, they can simply lower the resolution and enjoy significantly smoother motion. Despite the lack of 4K@120Hz, Hisense E7Q / E79Q really performs well as a television for gamers – especially those who are not looking for perfection, but a solid and fast screen for everyday gaming.
