Hisense S7NQ CanvasTV vs Philips OLED820

When it comes to the brightness of the television and how it handles bright elements while watching movies, it is just average—similar to contrast. The average brightness level of the Hisense S7NQ is around 500 nits. This is a value that allows you to feel the beginnings of true HDR, but it is definitely too little to speak of outstanding effects. However, the television deserves praise for color gamut coverage—movies look very colorful and vibrant. With the use of PFS LED (QLED) coating, the device can cover over 90% of the DCI-P3 color gamut and over 72% of the wider BT.2020 gamut. For a television in this class, these are truly very good results.

When it comes to HDR quality, the Philips OLED820 uses the same class of WOLED panel that we find in its biggest competitors – LG C5 or Samsung S90F. This means we can count on truly solid performance. This year, mid-range OLED panels are capable of exceeding the threshold of a thousand nits, and the model tested reaches around 1300 nits in some films. This is an outstanding result that allows for an extremely precise depiction of the director's vision, as contemporary productions are mastered in such brightness ranges. Of course, there are situations where even the OLED820 has to compromise. Full-screen scenes flooded with white, like those in the movie The Meg, can drop brightness to 400–500 nits, which clearly weakens the effect. This is a characteristic of OLED technology that has not yet been fully eliminated. Despite this limitation, it is hard not to appreciate the HDR in this model – high luminance and wide coverage of the DCI-P3 color gamut at 99% make the picture simply look great.

Let's now check how the Hisense S7NQ CanvasTV performs in color reproduction in the best factory mode, which is Filmmaker. Right from the start, it is evident that it is definitely better than in dynamic or standard mode, but there are still a few things to nitpick. In terms of image quality from the HD signal, the colors are slightly inaccurate – there is a dominance of cooler shades of blue and a lack of red. Because of this, the image appears somewhat too cool.

A similar effect occurs with 4K content, but it is more noticeable there. The excessive exposure of blue tones and the lack of red make the image seem distinctly cold. However, the biggest issue with this television is not the colors themselves but rather the way brightness is managed. The tested unit slightly boosted the brightness compared to the reference value. The result is indeed better visibility of details, but at the cost of significantly brightened black – which makes the entire image seem more "flat."

A similar phenomenon was noticed in the 4K signal – the slightly inflated curve at the beginning of the EOTF graph shows that the television has a tendency to excessively expose certain scenes. Fortunately, this effect can be improved with professional calibration, which we will discuss in the next point.

The color reproduction in the factory settings really surprised us, and positively so. The Philips OLED820, switched to Filmmaker mode, immediately showed that it was quite well tuned in terms of color. The white balance was relatively accurate, though with a slight lack in the blue hue, which sometimes gave the image a slightly yellowish tint. However, this is not a flaw that particularly interferes with everyday viewing. A larger problem arose with the brightness characteristic. The gamma chart clearly deviated from the ideal, with the line being below the expected values, causing the image to be overly brightened, and the colors looked as if they were covered with a light milky filter. This effect was also noticeable in tests using the Colour Checker pattern, where more pronounced errors appeared.

The results we achieved after calibrating the Hisense S7NQ are really very good. Thanks to the calibration, we were able to eliminate the excessive exposure of blue tones and the lack of red in the HD signal. A similar, although slightly weaker effect was also achieved with 4K HDR content. Brightness management in HD material has also improved – the television no longer has problems with overall image brightness issues.

However, there are things that cannot be overlooked. The characteristic of the EOTF curve has practically not changed, and the lack of local dimming means that the smallest elements on the screen will always be slightly overexposed. One simply has to accept this when choosing a television with a similar type of backlighting. Nonetheless, the final result is very good and should fully satisfy the vast majority of users.

After calibration, both the Filmmaker mode and the game mode gained quite a lot. A slight adjustment of the white balance and an improvement in brightness characteristics resulted in excellent outcomes for SDR content – the image looked almost perfect, natural and very close to the reference. In the case of HDR materials, the situation was similar; the colors looked stunning and it was hard to find anything to criticize. However, we noticed a certain feature that we had already pointed out when comparing scenes from the movie Billy Lynn. An analysis of the EOTF curve revealed that the television has a slight tendency to dim details in the blacks, which means that the darkest sections are not always displayed exactly as the director intended. Nevertheless, the effect after calibration is remarkable, and the OLED820 stands out as one of the more interesting screens in its class. It just needs a little bit of fine-tuning, and there's really nothing to be afraid of.

It is equally important how the television handles tonal transitions on a poorer signal – for example, in older movies, television, or on YouTube. Unfortunately, despite the presence of the "Smooth and Gradient Picture" feature, which was supposedly intended to improve this aspect, its performance is truly lacking. It is barely noticeable that it has any real impact on the visibility of color transitions.

Image scaling also performs poorly. Yes, one can observe that the television tries to "stretch" the quality, but the final effect is far from ideal. The image often appears slightly jagged, which is especially noticeable in the case of tree branches in the background. Additionally, the Hisense S7NQ has a clear tendency to crop the image at lower resolutions, which can cause us to miss captions in the news or finer details of the image.

Fortunately, the earlier effects of the aforementioned posterization can be quite effectively mitigated. The "distortion reduction" feature set to medium handles unwanted color banding, improving the smoothness of tonal transitions. It does happen, however, that it works a bit too aggressively and smooths out some details – such as minor skin imperfections of the actors – but despite this, it can be considered worth using without major compromises. The upscaling in the OLED820 also performs well. The test image with the model is exceptionally soft, sometimes even too much so, although this can be alleviated by slightly increasing the sharpness in the picture menu – it’s a matter of personal preference. The lack of overscan issues with very low-resolution content is also commendable, meaning we don't have to worry that the image will be unnecessarily cropped.

When it comes to motion fluidity, the television performs really well. Although the S7NQ was mainly designed for displaying static elements – such as images – the manufacturer has utilized a panel with a refresh rate of 144 Hz. As a result, sports or games look really good on it.

For materials that are not recorded at a high frame rate, the manufacturer provided two features that allow you to adjust the picture to your own preferences. "Motion blur reduction" and "motion smoothing" operate on a 10-level scale, allowing you to choose between a more cinematic image – with characteristic frame jumps – and a smooth effect reminiscent of a "soap opera." How to set this up? That's a personal matter – we leave the decision to you.

Motion fluidity is an area where OLEDs always shine, and the Philips OLED820 confirms this rule. The panel itself offers a refresh rate of 144 Hz, which will mainly benefit PC gamers, but even with standard television sources or consoles, where 120 Hz is used, the motion is fast, sharp, and simultaneously smooth, without traces of ghosting. This is thanks to the outstanding response time between pixels, which ensures the image retains clarity in every dynamic scene. The manufacturer has also added its own smoothing feature called "Motion Style." In the menu, we find two sliders – the first, responsible for fluidity, allows us to adjust the amount of artificially added frames in movies. This way, we can choose a raw, cinematic character with a clearly visible film frame or a more theatrical image with smooth motion. The second slider is for reducing blurring, especially useful in sports broadcasts. Here, we definitely recommend setting it to the maximum value, as the effect is truly excellent.

Even though the S7NQ is an "image" type TV, you can actually play games on it. Really. It has almost everything (except for HGiG mode) that a modern gaming TV needs. The 144 Hz panel and two full-fledged HDMI 2.1 ports allow for seamless connection of two consoles, such as PlayStation 5 or Xbox Series X/S.

The TV supports automatic game mode (ALLM) and frame synchronization (VRR) without any stuttering or issues. It also handles high frame rates at lower resolutions without a hitch. We must commend Hisense for the very attractive Game Bar – it displays all available picture options, and additionally, we have the ability to zoom in on the mini-map or enable a crosshair (because sometimes someone might actually want to "aim" 😉).

The only missing element – as we mentioned earlier – is the lack of a proper implementation of HGiG mode. It is responsible for automatically setting the picture in games as the creators intended. It's a shame because that’s the only thing separating the Hisense S7NQ from being a full-fledged gaming "monster."

Philips OLED820 is one of the most complete televisions for gamers. It practically has everything you could expect: two HDMI 2.1 ports with full bandwidth of 48 Gbps (too bad there aren't four), variable refresh rate VRR, automatic game mode ALLM, support for Dolby Vision in games, and a good implementation of the HGiG mode. The television also handles lower resolutions at 120 Hz without any issues, so you can count on great flexibility when choosing different picture modes on the console. Philips also adds Game Bar – a panel that allows you to change picture modes, add a crosshair, or view parameters. Although it looks quite clunky and is less polished than that of the competition, it serves its purpose. In practice, therefore, the OLED820, besides having a full set of four HDMI 2.1 ports, offers almost everything a gamer might need.
