Hisense E8Q vs Philips OLED811

Since the E8Q is a twin of the U7Q, it’s no surprise that the HDR effect quality is almost identical. On paper, it looks promising – a peak brightness of 800 nits can impress in many scenes. Moments like light flashes in “The Meg” or shots of the sun in “Life of Pi” can indeed create 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 protect the contrast, but in the process, they also dim 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 will not always be fully preserved. Fortunately, the colour reproduction provides reasons to be pleased. A coverage of the DCI-P3 palette of about 94% is a very good result, and the quantum dot layer used (more precisely, PFS) does its job – colours are saturated and vibrant, especially with 4K content.

Philips OLED811 uses the new generation WOLED EX panels, also found in models like the LG C6 and Samsung S90H. After calibration we measured about 1500 nits, which is a very good result for an OLED TV. You can see that clearly in films and series. Flashes of light have the right punch, especially when they appear on a dark background. In those scenes the OLED811 can deliver really impressive HDR. Of course this doesn't mean you'll see that level of brightness in every shot. When the screen is filled with a large area of white or a wide explosion, brightness falls to around 600 nits. That's still a good result, but such scenes don't have the same impact as small bright elements on a dark background. That's a known limitation of OLEDs and the OLED811 is no exception.

Colours

Aside from HDR brightness, colours also matter and here Philips also performs very well. It covers almost the entire DCI-P3 gamut, which contains most of the colours used in HDR films and series. So you get rich reds and lush greens, and while watching it's hard to fault it in that regard. It looks a bit worse with the much wider BT.2020 gamut — its most saturated shades are already beyond the reach of this panel. There's also the issue of the white subpixel that the WOLED panel uses to help boost brightness. With very bright colours you can see a certain "washout": the colour is bright but loses some of its intensity. It's in exactly these situations that Samsung Display's QD-OLED panels have the advantage. In most films and series, though, this won't be something that immediately jumps out at you.

Testing the Hisense E8Q in Filmmaker mode, we were hoping for a potentially neutral picture resembling the director's vision. Unfortunately – although it doesn't look too bad on paper (the colour reproduction errors aren't significant), in practice the image feels somewhat unnatural. The reason? The blue colour is boosted too strongly and there is a deficiency of red in the white balance. The effect? Scenes appear cool, and the white seems 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 on the screen to maintain contrast – but sometimes it goes too far. On the other hand, it can excessively brighten larger, very bright areas, which disrupts tonal balance. It's a compromise that may not suit everyone – especially if you want a potentially faithful picture straight out of the box.

The film mode on the Philips OLED811 is sensibly set up straight out of the box. Most colour errors remain minor in both SDR and HDR, so you can comfortably sit down to watch without adjusting the settings first. There are no large inaccuracies that would immediately distract from the film.

It’s not quite perfect, though. The white balance shows a slight lack of red relative to green, so whites and greys can have a faint greenish tint. It’s not a strong colour cast, but measurements clearly show it. There are also small luminance deviations in SDR: some parts of the image are slightly brightened, and the deepest tones aren’t always reproduced evenly. In HDR the TV stays much closer to the reference, although it occasionally lifts detail from the shadows. These are generally things that can be refined. The factory film mode provides a good starting point, and calibration will reveal how much more you can get out of it.

Calibration of the Movie mode yielded really good results, especially regarding SDR content. The white balance was successfully adjusted, giving the image a natural look – it appeared almost reference-level. The colours were well-saturated, and the overall experience of the content improved significantly. Unfortunately, when we switched to HDR materials, the familiar issues from the U7Q model returned. The TV still likes to "do its own thing," as seen from the analysis of the EOTF brightness characteristics – despite calibration, the E8Q still darkened small details in the shadows, while brighter parts of the screen were sometimes excessively boosted. In practice, this means that in darker scenes, some of the smallest details could simply disappear. Although it's worth noting that the entire calibration process brought a lot of good, not everything can be bypassed – even with the use of professional tools. The E8Q can impress with its picture, but in HDR content, its construction limitations become apparent, and it's worth keeping this in mind.

After calibration the Philips OLED811 delivers an image very close to the reference. We managed to even out the white balance and remove the slight colour cast visible in the factory settings. ColorChecker errors for SDR and HDR fell to around 1 to 2, with many samples even below 1. That's a level at which differences from the reference are hard to spot with the naked eye. We also improved the gamma, with only a slight lift remaining in the brightest whites. In HDR the EOTF curve also stays close to the reference, although the TV still tends to slightly boost the brightness of small details, such as stars or subtitles. That gives the picture a bit of extra brightness that shouldn't be there, but otherwise it's hard to find fault. It was already good out of the box, and calibration allowed us to iron out most of the remaining issues.

In the case of older materials of lower quality, gentle smoothing of tonal transitions often comes in handy. The Hisense E8Q, like the U7Q, has a "Smooth and Gradient Picture" feature, but unfortunately, its effectiveness leaves much to be desired. The "Low" setting is nearly invisible in operation, while higher settings blur details instead of improving transitions. The good news is that the feature does not compromise film grain, which means it does not degrade the structure of the image. On the positive side, scaling is commendable. The TV can reasonably convert older content to a higher resolution – without artificially accentuating contours or excessive sharpening. Although it doesn't match the best models in this category, it performs quite well for its class.

The OLED811 handles processing lower-quality material reasonably well, though it's far from perfect. The "Banding reduction" function helps smooth tonal transitions and on the low setting gives a pretty good effect. It doesn't remove banding between shades as effectively as similar solutions from some competitors, but at least it doesn't introduce new artefacts. It's a sensible setting for everyday viewing. Still, there's a bit of a letdown, because the MediaTek Pentonic 800 chipset used here can, in other manufacturers' hands, deal with the effects of heavy compression more effectively even at similarly low settings. A lot therefore depends on how a given manufacturer uses its capabilities.

We have a few more comments about the upscaling to 4K. There's plenty of detail, but overall the image looks rather soft. Edges are heavily smoothed, so the picture lacks some sharpness and clarity. You can partially correct this with the sharpness slider in the menu, though that will be extra edge enhancement rather than recovering detail. On the plus side, there's no overscan, and even with an SD signal the TV doesn't crop the edges of the picture.

Similar to the U7Q, the E8Q model is a fast television designed with dynamic content in mind. It supports a 144 Hz refresh rate 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 gives us two sliders, allowing you to set the picture to your preference – whether it's more cinematic with the film frame preserved or highly smoothed, almost “TV show-like.” It's good that the manufacturer provides a choice here, instead of imposing one style. On sports material, live broadcasts, or in games – motion looks clean and stable. Sure, it’s not at the OLED level, but for this price range, the E8Q does a really good job.

In terms of motion handling the OLED811 performs superbly. At 120 Hz, which is useful for console gaming and watching sport, the image remains clear and moving objects don't leave noticeable trails. The OLED's fast pixel response helps here. You can see it clearly in the UFO test, even on a dark background. There are also controls for motion smoothing. In movies you can adjust the strength of smoothing to your taste, from preserving a cinematic feel to much smoother motion. A separate blur-reduction control is useful for fast-paced content like live sports broadcasts.

Hisense E8Q does not hide its gaming pedigree. Just 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 Game Mode switching (ALLM)? That's there too. Additionally, there's impressive refreshment – 120 Hz in 4K or even 240 Hz in Full HD. Such a set is rare in this price segment. Everything runs smoothly and without major surprises. The only missing element – similar to the U7Q – remains support for HGiG. It's a shame because this feature facilitates adjusting the brightness curve to the capabilities of the specific television, enhancing visual fidelity with the intentions of HDR game developers. Without it, manual tweaking of the settings is necessary, which does not always yield a satisfying result.

The OLED811 has almost everything you’d expect from a TV for gaming. It supports 120 Hz at Full HD, 1440p and 4K, and when connected to a PC it can reach up to 165 Hz. It also offers VRR to help avoid screen tearing when frame rates fluctuate, and ALLM, which automatically switches to game mode. So you don’t have to go into the settings every time you start your console.

Another plus is the properly working HGiG, which ensures that once HDR is set on the console the TV doesn’t apply its own changes to image brightness. The Game Bar is also available, letting you check signal parameters and quickly change settings useful while gaming. The list even includes Dolby Vision for games, but there’s a significant catch here, which you’ll read about below.
