Panasonic W70A vs Hisense E7Q / E79Q

HDR on the Panasonic W70A unfortunately does not impress. Brightness at the level of 250–300 nits is simply too low to feel the true magic of cinematic effects in dynamic, bright scenes. Images that should "explode" with light appear rather flat, and fine details in bright areas often get lost in the average luminance of the panel. On the positive side, the HDR effect is at least stable. The TV does not suffer from excessive brightening nor does it lose details during sudden scene changes. Everything is predictable and calm, though unfortunately not very spectacular. Another issue is the color gamut coverage. The W70A is not equipped with an additional layer of quantum dots (often known as QLED), resulting in colors appearing rather mediocre. There is a lack of depth in reds, saturation in greens, and precision in rendering subtle shades.

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.

The Panasonic W70A was tested in movie mode, which theoretically should guarantee the most natural image reproduction. Unfortunately, as is often the case with budget televisions, the reality proved far from ideal.

In HD (SDR) content, the white balance was severely disrupted by an excess of red and a noticeable drop in blue tones. The result? The image had a distinctly warm, even yellowish tint, which is clearly visible in the comparison photo. In the case of 4K HDR materials, the situation reversed. Here, the image became excessively cold and bluish, causing scenes to lose their naturalness and depth. The differences are visible even to the naked eye, especially in the bright parts of the image. The Colour Checker palette test confirmed our observations. Most color samples did not hit their intended points, "running away" towards warmer shades in SDR and cooler ones in HDR. As for brightness characteristics, both gamma and the EOTF curve showed significant problems. The image tended to excessively brighten certain areas, disrupting the balance and leading to a loss of details in darker and brighter regions.

In summary – the factory color reproduction settings in the Panasonic W70A leave much to be desired. The image is far from neutral, and the errors in white balance and gamma mean that a solid calibration is needed to extract the full potential from this television.

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.

The Panasonic W70A, despite its limitations, gave us a lot of room to maneuver during calibration. Thanks to well-developed tools, we were able to achieve significantly better white balance in both HD (SDR) and 4K HDR content. The issues with excess red in SDR and overly cool images in HDR have disappeared. The gamma brightness characteristic has also improved, maintaining stability and avoiding excessive brightness or loss of detail in darker areas.

So where is the problem? Unfortunately, there are barriers that even professional calibration cannot overcome. Poor coverage of a wide color gamut means that the TV cannot fully reproduce colors in HDR materials. There is a lack of saturation, and subtle color transitions still appear somewhat "flattened." Another limitation is brightness management, which results from the use of an IPS panel. In the comparative photo featuring the actress's face in colorful clothing, it is clearly visible how some shades are noticeably muted, and colors lose their depth and brightness.

The calibration extracted everything it could from the W70A. The image is now much more natural, and the errors in the factory settings have been effectively corrected. Unfortunately, hardware limitations in the form of poor color gamut coverage and an average panel prevent us from achieving spectacular results, especially in HDR content.

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.

We checked how the Panasonic W70A performs in improving content of lower quality than 4K, and it must be admitted that the television does quite well in this regard. The "Zeroing Counter" function is responsible for smoothing tonal transitions. The optimal setting turned out to be the Average option, which effectively smooths out color gradation issues while not ruining the film grain. This is the setting we recommend for most users, as it provides a balance between improving the fluidity of transitions and maintaining the naturalness of the image.

As for image scaling, the Panasonic W70A performed really well. The test pattern with the model was positively evaluated – details on her clothing were well reproduced, and the contours of her face retained sharpness. In the background, we noticed slight "jaggies" on thin branches, but these are details that only a very observant eye will catch. However, it is worth noting a certain flaw of this model – the television has a tendency to overscan, which means slight cropping of the image edges. This is not a very intense phenomenon and for most users it will be practically unnoticeable, but if we care about perfect framing, it is worth keeping this in mind.

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.

The Panasonic W70A is equipped with a 60 Hz panel, which immediately suggests that the television will perform best when watching movies, series, or everyday TV content. In more dynamic scenes, such as sports broadcasts or games, the panel's limitations become more noticeable. On the positive side, it is worth noting the presence of a motion smoother called "Effect," which offers three levels of adjustment - low, medium, and high.

Each of the settings allows you to adjust motion fluidity to your own preferences, minimizing motion blur and improving clarity in dynamic shots. In practice, the Medium setting seems to be the most versatile - it offers better fluidity without excessive "soap opera effect," which can look artificial in feature films. The High setting may work well for sports broadcasts, but in films, it can disrupt the natural character of movement.

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 Panasonic W70A is a television that will be more suitable for occasional gamers than for avid players. The 60 Hz panel does not allow for full utilization of the potential of new generation consoles, especially in dynamic titles. The lack of HDMI 2.1 somewhat limits its capabilities, but fortunately, we find features such as ALLM, which is automatic switching to game mode, and VRR, which helps minimize screen tearing. It's also worth noting the support for Dolby Vision in games and HGiG, which makes HDR more predictable and looks solid. It's just a pity that the Game Bar is missing. This feature is already standard in many televisions and provides quick access to the most important settings for gamers. The W70A holds up when it comes to gaming, but it has its limitations. It works well with calmer titles, while more demanding players may feel unsatisfied.

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.
