Hisense E8Q vs Philips OLED820

Since the E8Q is a twin of the U7Q, it’s no surprise that the quality of the HDR effect is almost identical. On paper, it looks promising – a peak brightness of 800 nits can impress in many scenes. Fragments like the flashes of light in “The Meg” or shots of the sun in “Life of Pi” can indeed evoke a “wow” effect. But the longer we watch, the more we notice the limitations. The problem arises when small, bright details are supposed to be displayed on a dark background. In such situations, the dimming algorithms try to preserve contrast but end up dimming what should shine the brightest. Instead of dazzling details, we get almost invisible points of light. This is typical for Mini-LED in this price segment and is not surprising – but it’s worth knowing that the HDR effect won't always be fully preserved. Fortunately, the color reproduction offers reasons to be satisfied. A coverage of the DCI-P3 color gamut at around 94% is a very good result, and the applied quantum dot layer (more specifically, PFS) does its job – colors are saturated and vibrant, especially with 4K content.

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.

Testing the Hisense E8Q in Filmmaker mode, we were hoping for a neutral image close to the director's vision. Unfortunately - although on paper it doesn't look bad (the color reproduction errors are not significant), in practice the image feels somewhat unnatural. The reason? Too strong an increase in blue and a lack of red in the white balance. The effect? The scenes look cool, and the white appears slightly bluish. Alongside the U7Q model, we also noticed a specific approach to brightness management here. The brightness reproduction curve for HDR content (EOTF) shows that the TV can significantly dim small, bright elements of the screen to maintain contrast - but sometimes it goes too far. On the other hand, it can excessively brighten larger, very bright parts, which disrupts tonal balance. This is a compromise that may not suit everyone – especially if you want an as faithful image as possible right out of the box.

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 calibration of the Movie mode brought really good results, especially regarding SDR content. The white balance was successfully adjusted, which gave the image a natural look – it appeared almost reference-level. The colors were well-saturated, and the overall perception of the content improved significantly. Unfortunately, when we moved to HDR materials, the well-known problems from the U7Q model returned. The TV still tends to “do things its own way,” which is evident from the analysis of the EOTF brightness characteristic – despite calibration, the E8Q still dimmed small details in the shadows, while the bright areas of the screen could sometimes be excessively boosted. In practice, this means that in darker scenes, some of the tiniest details could simply disappear. Although it must be admitted that the entire calibration process brought a lot of good, not everything can be circumvented – even with the use of professional tools. The E8Q can impress with its picture, but in HDR content, its design limitations become noticeable, and it is worth keeping this in mind.

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.

In the case of older materials with lower quality, a gentle smoothing of tonal transitions is often useful. The Hisense E8Q, like the U7Q, has the "Smooth and Gradient Picture" feature, but unfortunately, its effectiveness leaves much to be desired. The “Low” setting is almost imperceptible in operation, while higher settings simply blur details instead of improving transitions. The good news is that the feature does not compromise the film grain, which allows it to maintain the image structure. On the plus side, the scaling is commendable. The television can fairly sensibly transform older content to a higher resolution—without artificially emphasizing contours or excessive sharpening. Though it does not match the best models in this category, it performs quite well for its class.

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.

Like the U7Q, the E8Q model is a fast television designed for dynamic content. It supports 144 Hz refresh rates in 4K resolution, and if for some reason someone is still gaming in Full HD, it can achieve even 240 Hz. This is a significant advantage, especially for PC users looking for maximum fluidity. In everyday use, the television performs very well. The "Ultra Motion Smoothness" mode provides us with two sliders, allowing for personalized image settings – whether it’s more cinematic with preserved film frames or heavily smoothed, almost "series-like." It’s good that the manufacturer gives a choice here instead of imposing one style. On sports materials, live broadcasts, or in games – motion appears clean and stable. Sure, it’s not at the level of OLEDs, but for this price range, the E8Q performs really well.

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.

The Hisense E8Q does not hide its gaming pedigree. The specification alone reveals that we are dealing with a television that will work great as a gaming screen. Variable Refresh Rate (VRR)? Yes. Automatic low latency mode (ALLM)? It's there too. Additionally, there is impressive refreshment – 120 Hz in 4K or even 240 Hz in Full HD. Such a set is rare in this price segment. Everything works smoothly and without major surprises. The only missing element – like in the U7Q – remains support for HGiG. It's a pity, because this feature makes it easier to match the brightness curve to the capabilities of a particular television, improving visual consistency with the intentions of HDR game creators. Without it, one has to manually tweak the settings, which does not always yield a satisfying result.

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.
