Philips OLED809/819 vs Hisense U7Q

Philips OLED 809 delivers a more than satisfactory HDR effect. The television is capable of generating luminance exceeding 900 nits in almost every scene, and sometimes even over 1000. This result allows for a full experience of materials with a wide tonal range. The only moment when Philips OLED 809 cannot generate higher brightness is in a scene from the film "The Meg," which features a large amount of bright white across much of the screen. However, it cannot be said that this is a weak result, as it represents a significant improvement over its predecessor. Overall, such values for OLED panels produced by LG Display, which do not have MLA technology, are very, very good. Combined with high coverage of the DCI-P3 colour gamut, they allow for an HDR experience in a remarkable dimension. Philips OLED 809 test indicated that this television supports popular HDR formats such as Dolby Vision and HDR10+.

Since the algorithms responsible for blacks are performing quite well, we expected a similarly good outcome when it comes to brightness and overall HDR quality. Unfortunately, we have to disappoint you a bit here.

The U7Q is quite a bright television – under the best conditions, it can reach around 800 nits, which indeed impresses in some scenes, especially in scenes like those from the movie The Meg. Bright segments can shine, and the HDR effect is noticeable. The problem arises when very small, bright elements appear on a dark background – for example, in Sicario 2 or in the second scene from Life of Pi. At such moments, the dimming algorithms operate too aggressively. Yes, the blacks look great at that point, but the brightest spots can almost completely disappear, causing the HDR effect to vanish and details to be barely visible. That’s just the charm of this technology in this price segment.

As a consolation, it is worth mentioning that the U7Q is marketed as a QLED (in practice, a PFS layer is used, which operates very similarly), and it can indeed display a wide colour gamut – a DCI-P3 coverage of around 94% is a very good result for this class.

The best factory mode in which we conducted all our tests was "Filmmaker", which is now quite standard in televisions from this manufacturer. However, let's take a look at its characteristics before we start the calibration process. The first aspect we will examine is white balance, as despite being inconspicuous, it determines whether the image will be free from any tints. The graph clearly shows that in both SDR and HDR content, two colours dominated: red and green, which caused a strong yellow tint that was pervasive throughout the image. This is perfectly visible on the "ColourChecker" palette, where all colours shifted towards their warmer counterparts. The second thing we will scrutinise are, in our opinion, the two most important graphs in the context of image quality assessment: gamma and the EOTF curve. Both are intended to maintain appropriate brightness and contrast. The first describes the level of brightness in SDR materials, while the second depicts the rate of luminance increase. Analysing the first one, we can see that it has been remarkably lowered compared to the reference value indicated by the orange line. This situation resulted primarily in a sharp increase in brightness and a significant decrease in contrast, reminiscent of what one would expect from OLED televisions. The EOTF curve showed greater "caution" and only slightly brightened the entire image to 50% of the maximum brightness.

We tested the U7Q in the best possible picture mode, which is Filmmaker Mode. This mode is supposed to provide the most "cinematic" experience that aligns with the creators' intentions – straight out of the box. Unfortunately… even this professionally sounding name doesn’t guarantee a perfect image.

In our unit, the problem lay in the poorly set white balance. In both HD and 4K content, the image had too much blue and red, resulting in a slightly pinkish hue on the screen. It didn’t look terrible, but it was noticeable – especially in bright scenes and on white backgrounds. That alone could have been forgiven, but the biggest issue is managing brightness in HDR content. The EOTF curve from the measurements confirms what we saw earlier during scene tests: the television can overly dim the smallest bright elements, causing them to nearly disappear, or conversely – excessively brighten the brightest parts, which affects the naturalness of the image.

Philips, like most leading manufacturers, has been providing advanced tools for the calibration process for years. Here, we find 2- and 20-point grey scale adjustments as well as an advanced CMS (Color Management System). As you can see, this has brought extremely beneficial results and fundamentally changed the perceived image. Practically every one of the elements mentioned above has undergone a transformation and has been returned to its natural state. This is particularly evident on the "ColourChecker" palette, where the measured samples are harmoniously in their places. It must be said that the white balance has turned out exceptionally well, allowing us to enjoy a clean image free from any tint in both SDR and HDR materials. The biggest issue with OLED809, which is gamma, has been properly modelled and only occasionally shows minor errors that won't affect the overall picture. The EOTF curve, on the other hand, has been stripped of that slight brightening and now presents itself almost referentially.

Thanks to specialist tools, we managed to correct the colour quality in SDR content to almost perfection. In materials with lower dynamics, delta E errors dropped below 0.5, which can be considered an almost reference result. The picture on television, YouTube, or classic Full HD looks really good after calibration. Well then – but where was it not so easy to improve the image? Primarily it concerns HDR quality content. Although we managed to somewhat "tame" the white balance and eliminate pink tints in most scenes, unfortunately, we did not have full control over brightness management. We set the local dimming settings according to the best observations – SDR: Medium, HDR: High – but the U7Q still did everything a bit its own way. There were still cases of overly strong dimming or brightening of details that calibration simply could not eliminate. And although the overall reception of content is much better, one must reckon that the U7Q will always have something to say at the end with "but".

Philips OLED 809 didn't perform too well in the test for the smoothness of tonal transitions. Moving on to the part of the test where we assess the behaviour of the TV's algorithms, we will again check the function responsible for removing posterisation. In fact, such a function exists in the menu and has several options available. As you can see in the photo on the left, although its presence has been confirmed by us, it is not useful. Only at the highest setting does it effectively remove disruptions, but it blurs the entire image in the process. Therefore, it is completely unusable.

Time and again, you and we find ourselves watching materials of lower quality. In this case, the quality of the image upscaling algorithms can have a salvaging effect. We must admit that those implemented in OLED 809 work quite efficiently and improve the image quality without visible artefacts. You can only notice slight edge blurring, but it is unlikely to be noticeable during normal viewing.

There are situations where we would like to smooth out tonal transitions a bit, especially in older materials – those with limited source quality. The U7Q has been equipped with a feature called “Smooth and Gradient Image,” but unfortunately… it works very poorly. In the “Low” option, the effects are practically unnoticeable, and other settings smooth out the details but don’t improve tonal transitions. The only positive thing is that the feature doesn’t interfere with the film grain, so it doesn’t ruin the natural structure of the image.

Fortunately, content scaling performs quite well. The image is not overly sharpened, there is no artificial clarity – and while it’s known that this isn’t the level of high-end TVs, the U7Q has no problem displaying really old content in a completely acceptable manner.

The maximum refresh rate we can set on the tested television is 144 Hz. This value can be achieved by connecting it to a really powerful PC. In the case of consoles or television, everything remains the same. For those who require high movement fluidity or dislike the characteristic judder of films recorded at 24 fps, the manufacturer has prepared a fairly advanced motion smoothing system. In the dedicated tab, we will find the “Smoothness” slider responsible for eliminating judder and “Blur Reduction”, which helps increase the sharpness of dynamic elements. The function works very well and granularly, meaning each of the settings has a real impact on the perception of motion. We also mention that it works at a refresh rate of 120 Hz, as it operates on the multiples of film or television materials. Thanks to such an extensive set, every user will find their happy medium. In the photo, we present our choice, which is slight smoothing without the soap opera effect.

Motion is influenced not only by the settings on the television but also by the response time of the panel itself. OLED televisions feature the best response time on the market, which in the case of 809 is about 0.1 ms. There are no IPS/ADS or even VA panels that significantly come close to the results of organic panels.

U7Q is a truly fast TV, much like its more powerful version “PRO”. At 4K resolution, it supports up to 144 Hz refresh rate, and if someone wants even more – in Full HD, you can achieve up to 240 Hz! This will mainly benefit PC gamers, but it’s worth appreciating – it’s a rare feature in this price segment. Right from the start, it’s clear that the U7Q has been designed with dynamic content in mind, such as games or sports. In films, we’re not left “out in the cold” either – the U7Q offers an “Ultra Motion Smoothness” feature, where with two sliders, you can adjust whether you want a smoother, theatrical picture, or something closer to cinematic style with a visible frame. It’s good that, like most manufacturers, we have a choice here and can customise it to our own preferences.

The Philips OLED 809 supports all the technologies included in the HDMI 2.1 standard, and during our tests, each one activated without any problems. Therefore, we must state that this television is perfect for all gamers, both those using a console and a computer. It's worth mentioning that the manufacturer has implemented the HGIG mode, which is a great alternative to Dolby Vision, which unfortunately on the OLED809 is unplayable due to the very high input lag.

A nod to gamers is also the inclusion of a dedicated GameBar, which allows monitoring of current gameplay parameters and quick adjustments of settings. There is also a function to activate a crosshair, which will be very useful when shooting from a sniper rifle, but from the so-called hip. Additionally, we can also find a shadow enhancement function for better visibility in shadows and a colour filter for gamers with visual impairments.

In summary, the OLED 809 is a very good and versatile device for gamers. Anyone who purchases this television for gaming does not need to worry about anything, as it is simply designed for gaming. Especially since features such as VRR, ALLM, G-Sync, FreeSync, and HDR Dolby Vision gameplay will allow for an even deeper immersion in their favourite title. Lastly, we should note that the only downside of the television in game mode is the artificial sharpening of the image, regardless of the settings, and it cannot be 'softened.'

The Hisense U7Q is a TV designed with gamers in mind – and you can see that straight away with its gaming capabilities. It has practically everything you could wish for: Variable Refresh Rate (VRR) – check, Auto Low Latency Mode (ALLM) – check, and high refresh rates of up to 240 Hz in Full HD, along with support for various resolutions, not just 4K. It’s truly an impressive set of features that makes the U7Q perform well with both fast-paced shooters on consoles and more demanding titles on PC. Of course – like most Hisense models – it lacks a proper implementation of the HGiG feature. It’s a shame because HGiG allows the console's brightness to be adjusted to the specific TV, which in practice makes it easier to display HDR games according to the creators' intentions. Without this, you just have to deal with some limitations in the final HDR image in games.
