TCL C655 / C69B (43" - 50") vs Hisense E7Q / E79Q

The quality of the HDR effect in the TCL C69B / C655 television is quite average. With a brightness level of 350 nits, although not the worst, it still doesn't allow for a full enjoyment of HDR effects, which require higher luminance to showcase their power. Additionally, despite the application of a quantum dot coating (QLED), the television offers an average coverage of the wide DCI-P3 colour gamut at 91%, which may limit its richness of colours in HDR content.

The Hisense E7Q / E79Q is a television with average brightness, with a peak luminance level of around 350-380 nits. This is an absolute minimum that allows for HDR content to be viewed in a way that is close to the creators' intentions, although without a distinct "wow" effect. Synthetic test results on white screens have been confirmed in practice – in film scenes, the bright parts of the image are stable and quite uniform, but it's hard to speak of a true "light punch." In everyday use, for example, when watching Netflix or YouTube, the HDR effect is acceptable and is perfectly sufficient for most users. However, it must be stated clearly – this is not the level of top-end screens, and one should not expect that in this price range. Fortunately, the Hisense E7Q / E79Q has an advantage that allows it to gain quite a few points: it features a PFS LED QLED panel, utilising an additional phosphor layer that improves colour reproduction. The measured range of the DCI-P3 colour gamut is about 92%, which means that colours in most scenes are vibrant, well-saturated, and pleasant to the eye, particularly for this price bracket.

The television TCL C69B / C655, tested in movie mode, unfortunately does not meet expectations in terms of colour accuracy. Although movie mode suggests better representation, it has almost nothing in common with film. There are many errors evident, particularly in white balance – for both HD and 4K HDR content – where the dominance of the blue colour is very noticeable. For the viewer, this means that the image becomes unnaturally cool, affecting the overall perception of colours and the visual impression. The colour checker confirms these errors, showing that colours shift towards cooler shades.

As for brightness characteristics and the related contrast, gamma is very unstable for the material, which can make the image slightly darker. The EOTF curve for the 4K material shows some errors, with significant deviations towards the end of the graph, which negatively impacts the reception of darker parts of the image.

In Filmmaker mode, the Hisense E7Q / E79Q television was truly impressive. After the first measurements, it became clear that the white balance was quite well tuned, with the only minor deviation being a slight tendency towards a purple tone, which we mentioned earlier. However, this did not significantly impact the overall character of the image – it remained coherent and pleasant to view. A much larger issue turned out to be the brightness characteristics (gamma) in SDR content and the EOTF curve in HDR films. The television noticeably brightened the image, flattening the contrast and diminishing its depth. Gamma values could drop from the reference 2.4 to around 1.9, making the image look as if it were covered with a thin, milky layer. Fortunately, this is a problem that can be relatively easily corrected through calibration.

After calibration, the movie mode on the TCL C69B / C655 television improves in quality. The greatest improvement can be seen in tonal quality, and the white balance presents itself much better – with no major errors. We will no longer see an excessive dominance of cool tones. Gamma has also been improved, leading to a more stable representation of brightness and contrast. However, due to limitations in the form of the television's average colour palette, Colour Checker tests for 4K materials did not achieve remarkable results. Despite these technological limitations, the image has become more authentic, positively affecting the reception of film content.

The biggest beneficiary of calibration in the case of the Hisense E7Q / E79Q was undoubtedly the SDR mode. It managed to achieve an almost perfect image – most errors in the Color Checker test dropped below a value of 3, and often even 2, which is an outstanding result for this class of equipment. The greatest improvement came from equalising the brightness characteristic (gamma), which meant the image no longer appeared washed out and regained its natural depth. In HDR content, it was also possible to improve colours and eliminate the purple tint mentioned earlier, 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 heavily, overemphasising some colours. This was also indicated by the EOTF curve, which was slightly above the reference values, suggesting these minor issues with excessive brightness. Despite this drawback and the design limitations that emerge with HDR content, the Hisense E7Q / E79Q gained quite a lot after calibration. In everyday use, the television presents a consistent, natural, and pleasant image, and the difference compared to the factory settings is enormous.

The "Gradual Smoothing" function works very well on the TCL C69B television and, surprisingly, does not remove desirable effects such as film grain – unlike some solutions from other manufacturers. When it comes to image scaling, unfortunately, it looks poor. The television artificially sharpens the image, causing the edges of objects to be quite jagged. This state of affairs may appeal to some users who prefer a more "hard" look to the image, but it is not an ideal solution for those who value naturalness and fluidity of details.

In the case of the Hisense E7Q / E79Q, upscaling and digital image processing are not the strongest aspects of this television. It is evident that the manufacturer has opted more for simplicity rather than advanced image processing algorithms. The television does not offer any features to smooth tonal transitions or systems to improve image clarity, resulting in lower resolution materials looking simply very raw. On the screen, you can notice subtle compression edges that better processors in other models can effectively hide.

During the HD material tests, we noticed that the E7Q tries to artificially enhance detail, which sometimes works, and at other times has the opposite effect – the image becomes soft, slightly blurred, at times even “watery.” There is no aggressive sharpening that ruins naturalness, but there is also no finesse in the detail integration that better image converters offer.

The TCL C69B / C655 television in its smallest variants offers decent, though not perfect, results in terms of motion smoothness. For films, the television features a "Flicker Reduction" function that allows adjustment of motion smoothness on a scale from 1 to 10. With this option, we can tailor the appearance of the image to our cinematic or more theatrical preferences (with either lower or higher speed).

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

The TCL C69B / C655 television in its smallest variants offers a range of features dedicated to gamers, such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), Dolby Vision for gamers, and Game Bar. ALLM automatically switches the television to low latency mode, improving responsiveness and minimising delays in control. VRR allows the screen refresh rate to synchronise with the number of frames generated by the console, eliminating screen tearing and providing smoother gameplay. Dolby Vision for gamers ensures better colour and contrast reproduction in games that support this format, resulting in enhanced picture quality. Meanwhile, Game Bar provides quick access to game settings and monitors key parameters such as input lag.

However, the television has certain limitations that may affect gaming comfort. The 60 Hz panel does not allow for displaying signals with higher refresh rates, which may impact the smoothness of the image in fast-paced games. The lack of support for G-Sync technology for PCs may also be noticeable when gaming on a computer, especially in demanding, fast-paced titles.

Hisense E7Q / E79Q is truly a successful television for gamers, even though it does not support 4K signal at 120 Hz. The manufacturer, however, has ensured a set of features that until recently could only be found in more expensive models. There is ALLM, meaning automatic switching to low latency mode, allowing the television to activate game mode with very low input lag by itself. We also have VRR, functioning up to 60 Hz – while this may not look impressive on paper, 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 interface, one can change picture modes, enable a frame counter, or even... an on-screen reticle – humorously named "target point" in the Vidaa system, which is a result of awkward translation from the Chinese manufacturer.

Special praise should be given to the ability to play in 1080p at 120 Hz, which significantly improves the fluidity and responsiveness of the image. Therefore, if someone wants to play a few titles at a higher refresh rate, they can simply lower the resolution and enjoy much smoother motion. Despite the lack of 4K@120Hz, the Hisense E7Q / E79Q performs really well as a gaming television – especially for those who are not looking for perfection but rather a solid and fast screen for everyday gaming.
