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 nearly identical. On paper, it looks promising – a peak brightness of 800 nits can impress in many scenes. Moments such as 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 need to be shown against a dark background. In such situations, the dimming algorithms try to preserve contrast but end up dimming what should shine the most. Instead of dazzling details, we get almost invisible points of light. This is typical for Mini-LEDs in this price segment and is not surprising – but it’s worth knowing that the HDR effect will not always be fully preserved. Fortunately, the colour performance offers reasons to be pleased. Coverage of the DCI-P3 colour gamut at around 94% is a very good result, and the applied layer of quantum dots (more precisely, PFS) does its job – the colours are saturated and vibrant, especially with 4K content.

When it comes to HDR quality, the Philips OLED820 uses the same class of WOLED panel found in its biggest rivals – the LG C5 and Samsung S90F. This means we can expect really solid results. This year, mid-range OLED panels can exceed the threshold of a thousand nits, and the tested model reaches around 1300 nits in some films. This is an outstanding result, allowing the director's vision to be conveyed with immense precision, as this is the brightness range in which contemporary productions are mastered. Of course, there are situations where even the OLED820 has to compromise. Full-screen scenes filled with white, like those in the film The Meg, can drop brightness to 400–500 nits, which clearly weakens the effect. This is a characteristic of OLED technology that has yet to be fully eliminated. Despite this limitation, it is hard not to appreciate the HDR in this model – high luminance and a wide DCI-P3 colour gamut coverage of 99% make the image simply look fantastic.

Testing the Hisense E8Q in Filmmaker mode, we were hoping for a possibly neutral image close to the director's vision. Unfortunately – although it doesn't look bad on paper (the colour reproduction errors are not significant), in practice the image appears not entirely natural. The reason? An overly strong boost in blue colour and a lack of red in the white balance. The effect? Scenes look cool, and the white seems slightly bluish. Alongside the U7Q model, we also noticed a specific approach to brightness management here. The brightness mapping curve for HDR content (EOTF) shows that the television can significantly dim small, bright elements on the screen to maintain contrast – but sometimes it goes too far in this. On the other hand, larger, very bright areas can be excessively brightened, 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 colour 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 colour. The white balance was relatively accurate, though there was a slight deficiency in the blue hue, which occasionally gave the image a slightly yellowish tint. However, this is not a flaw that particularly detracts from everyday viewing. A bigger issue arose with the brightness characteristics. The gamma curve clearly deviated from the ideal, with the line below the expected values, causing the image to be excessively brightened, and the colours 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 yielded really good results, especially when it comes to SDR content. We managed to balance the white levels, which made the image look more natural – it appeared almost reference-quality. The colours were well-saturated, and the overall perception of the content improved significantly. Unfortunately, when we switched to HDR materials, familiar issues from the U7Q model returned. The television still likes to "do its own thing," as evident from the analysis of the brightness characteristic EOTF – despite calibration, the E8Q still dimmed fine details in the shadows, while the bright areas of the screen could be excessively boosted. In practice, this means that in darker scenes, some of the smallest details could simply disappear. Although it must be acknowledged 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 apparent, and it is worth keeping this in mind.

After calibration, both the Filmmaker mode and the gaming mode gained a lot. A slight adjustment of the white balance and an improvement in brightness characteristics produced excellent results in SDR content – the image looked almost perfect, natural, and very close to reference. In the case of HDR materials, the situation was similar, the colours were presented wonderfully, and it was hard to find anything to criticise. However, we noticed a certain feature, which we already pointed out when comparing scenes from the film Billy Lynn. The analysis of the EOTF curve showed that the television has a slight tendency to dim details in the blacks, so the darkest parts are not always displayed exactly as intended by the director. Nevertheless, the effect after calibration is stunning, and the OLED820 is emerging as one of the more interesting screens in its class. It just needs a little pampering, and there really is nothing to worry about.

In the case of older materials with lower quality, a gentle smoothing of tonal transitions often comes in handy. The Hisense E8Q, like the U7Q, features an "Smoothing and Gradient Image" function, but unfortunately – its effectiveness leaves much to be desired. The "Low" mode is almost imperceptible in operation, and the higher settings do not improve transitions but simply blur the details. The good news is that the function does not compromise film grain, meaning it does not worsen the structure of the image. On the plus side, scaling is commendable. The television is able to sensibly upscale older content to a higher resolution – without artificially accentuating contours or excessive sharpening. Although it does not match the best models in this category, it performs quite well for its class.

Fortunately, the earlier effects of the mentioned posterisation can be quite effectively mitigated. The "distortion reduction" function set to a medium level deals with unwanted colour banding, improving the smoothness of tonal transitions. It does happen that it works a bit too aggressively and also smooths out some details – such as minor skin imperfections of the actors – but nevertheless, it can be considered worth using without substantial compromises. The upscaling in the OLED820 also performs quite well. The test image with the model is exceptionally soft, sometimes even too much so, although this can be rectified by slightly boosting the sharpness in the picture menu – this is really a matter of individual preference. The absence 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.

Similar to the U7Q, the E8Q model is a fast television designed for dynamic content. It supports a refresh rate of 144 Hz at 4K resolution, and if, for some reason, someone is still gaming in Full HD – it can even reach 240 Hz. This is a significant advantage, especially for PC users looking for maximum smoothness. In everyday use, the television performs very well. The "Ultra Motion Smoothness" mode offers two sliders that allow you to customise the picture to your preference – whether more cinematic with the film frame preserved or highly smoothed, almost "series-like". It's good that the manufacturer provides a choice here instead of imposing one style. On sports material, live broadcasts, or in games – movement looks clean and stable. Of course, it is not at the OLED level, but for this price range, the E8Q performs really well.

The fluidity of motion 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 primarily benefits PC gamers, but even with standard television sources or consoles, where it operates at 120 Hz, the motion is fast, sharp and simultaneously smooth, without signs of blurring. This is thanks to the remarkable response time between pixels, which maintains image clarity in every dynamic scene. The manufacturer has also added its own smoother called "Motion Style". In the menu, we find two sliders – the first, responsible for fluidity, allows adjustments to the number of artificially added frames in films. This way, we can choose a raw, cinematic character with a distinctly visible film frame or a more theatrical image with smooth motion. The second slider is for motion blur reduction, particularly useful in sports broadcasts. Here, we definitely recommend setting it to the maximum value, as the effect is truly excellent.

Hisense E8Q does not hide its gaming heritage. Even the specifications reveal that we are dealing with a television that will perform excellently as a gaming screen. Variable Refresh Rate (VRR)? It's there. Automatic switching to game mode (ALLM)? That's there too. Additionally, there is impressive refresh rate – 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 – similar to the U7Q – is support for HGiG. It’s a shame, as this feature facilitates adjusting the brightness curve to the capabilities of a specific television, improving visual compatibility with the intentions of HDR game creators. Without it, one has to manually fiddle with the settings, which does not always yield a satisfactory result.

The Philips OLED820 is one of the most complete televisions for gamers. On board, we find practically everything one could expect: two HDMI 2.1 ports with full bandwidth of 48 Gbps (it's a shame 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 handles lower resolutions at 120 Hz with ease, so one can count on considerable flexibility when choosing different picture modes on the console. Philips also includes a Game Bar – a panel that allows changing picture modes, adding a crosshair, or previewing parameters. Although it looks rather clunky and is less polished than that of the competition, it does its job. In practice, therefore, the OLED820, in addition to a full set of four HDMI 2.1 ports, offers nearly everything a gamer could need.
