Philips OLED809/819 vs Hisense UR8S

Philips OLED 809 delivers a more than satisfying HDR effect. The television is capable of generating brightness exceeding 900 nits in almost every scene, and sometimes even over 1000. This result allows for a full experience of content with a wide tonal range. The only moment when Philips OLED 809 is unable to generate higher brightness is in a scene from the movie “The Meg,” which features a large amount of bright white across a significant portion of the screen. However, this cannot be regarded as a poor result, as it represents a considerable improvement over its predecessor. Generally speaking, such values for OLED panels produced by LG Display, which do not feature MLA technology, are very, very good. When combined with high coverage of the DCI-P3 colour gamut, they allow for an exceptional HDR experience. The Philips OLED 809 test showed that this television supports popular HDR formats such as Dolby Vision and HDR10+.

UR8S is a slightly higher-end Mini-LED, so you could expect a lot in terms of brightness. And indeed, on a synthetic test pattern peak brightness reached around 2200 nits. That’s a very good result, but as always what’s much more important is what the TV does in normal film scenes. Here the results are a bit more uneven. In bright scenes, where there’s a lot of light on screen, the UR8S can deliver really strong HDR. Brightness then reaches about 1500 nits, so the image is very intense and has plenty of punch. It’s worse with small bright elements on a dark background. The TV clearly dims them to keep good blacks and to prevent excessive bloom. As a result things like single stars or tiny reflections can be only around 200 nits. And here HDR is no longer as impressive. So you can see that the local dimming algorithm works effectively, but it also has its cost: sometimes it simply sacrifices the brightness of small details in favour of contrast.

Colours

With RGB Mini-LED TVs colours should be judged a little differently than usual. If we look solely at the panel’s native capabilities, the UR8S performs excellently. We measured around 94% coverage of BT.2020 and practically full DCI-P3. These are among the highest values currently found in LCD TVs and this is where the potential of the RGB backlight is most obvious. The problem is that this potential is not always realised in real scenes. When we ran the same measurements on test patterns with a film background applied, saturation of some colours began to fall noticeably. Individual zones are not always able to control the three RGB components so precisely when the scene becomes more complex. This is most visible with blue and magenta. On simple test patterns they can look very strong, but in more demanding scenes samples of those colours visibly shrink. So the UR8S’s capabilities are enormous, it’s just that the TV cannot fully make use of them in every scene.

The best factory mode in which we conducted all our tests was "Filmmaker", which has become rather standard in televisions from this manufacturer. However, let's check what its characteristics were before we began the calibration process. The first aspect we will examine is white balance, as despite appearing unassuming, it determines whether the image will be free from any kind of tint. The graph clearly shows that both in SDR and HDR materials, there was a dominant presence of two colours: red and green, which resulted in a strong yellow tint that was ubiquitous across the entire image. This is perfectly visible on the "ColourChecker" palette, where all hues shifted towards their warmer counterparts. The second thing we will scrutinise is, in our opinion, the two most important graphs regarding image quality assessment: gamma and the EOTF curve. Both aim to maintain adequate brightness and contrast. The first one serves to describe the brightness level in SDR materials, while the second shows the rate of luminance increase. Analyzing the first one, we can observe that it was extremely lowered compared to the reference value marked by the orange line. This situation resulted primarily in a sharp increase in brightness and a significant reduction in contrast, almost reminiscent of that in OLED televisions. The EOTF curve exhibited greater "moderation" and only slightly brightened the entire image to 50% of the maximum brightness.

For assessing the out-of-the-box colours we used Filmmaker mode, which is intended to show an image that is as close as possible to how the material was prepared. Looking at the white balance alone, the UR8S performs quite well. There is no strong tint that immediately jumps out, although as brightness increases a little too much blue and red start to appear, with a simultaneous shortfall of green. Colour errors therefore show up in measurements, but the image itself does not look bad. We have far greater reservations about how the UR8S manages picture brightness. In SDR the gamma sits around 1.9–2.0 for most of the range instead of the target 2.4. In practice this simply means the picture is too bright, especially in the midtones. Shadows are lifted too much, causing the image to lose some depth. A similar tendency is visible in HDR. The EOTF curve is above the reference value for a large part of its range, so the UR8S again brightens the image more than it should. This is not due to a lack of brightness — the TV has plenty — but to the way it manages that brightness. As a result, HDR content can look very striking, but not always precisely as it should.

Philips, like most leading manufacturers, has been providing advanced tools for calibration processes for years. Here we will find both 2- and 20-point grey scale adjustments, as well as an advanced CMS (Colour Management System). As you can observe, this has brought about extremely beneficial results and profoundly changed the perceived image. Practically every one of the elements mentioned above has undergone a transformation and has been brought back to its natural state. This is particularly evident on the "ColourChecker" palette, where the measured samples are harmoniously in place. 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 of OLED809, namely gamma, has been properly modelled and only shows minor errors here and there, which will not affect the overall picture. The EOTF curve, on the other hand, has been rid of that subtle brightening and now presents itself as reference-level.

Hisense provides plenty of calibration options and, in SDR, these can yield a very good result. After calibration, the white balance is practically even across the entire range, and colour errors fall to very low values. The UR8S can be adjusted very precisely here. HDR is somewhat different. The white balance itself can also be noticeably improved, although at the highest brightness levels larger deviations begin to appear. The most interesting aspect, however, is the behaviour of the EOTF curve. Even after it has been correctly set on test patterns, the UR8S still tends to interpret brightness in its own way when watching films. Depending on the scene, parts of the image are slightly brightened while others are dimmed relative to how they should appear. This shows that the algorithms controlling the local dimming have a significant influence on the final image. Calibration therefore allows colours to be improved very effectively, but we are not able to completely 'turn off' the way the UR8S manages brightness in HDR.

Philips OLED 809 did not perform particularly well in the test of tonal transition fluidity. Moving on to the part of the test where we assess the behaviour of the television's algorithms, we will once again check the function responsible for removing posterization. Indeed, such a function exists in the menu and has several available options. As you can see in the picture on the left, although its presence has been confirmed by us, it is not useful. Only at the highest setting does it effectively remove stuttering; however, it blurs the entire image in the process. Therefore, it is completely useless.

It happens more than once or twice that you and we watch lower quality materials. In this case, the quality of the image upscaling algorithms can have a beneficial effect. We must admit that those implemented in OLED 809 work quite efficiently and improve image quality without visible artifacts. You can only notice slight edge fringing; however, it is unlikely to be visible during normal viewing.

A big plus of the UR8S is the use of the MediaTek Pentonic 800 processor, and digital image processing is one of this model's stronger points. The TV handles smoothing tonal transitions very well, especially with lower-quality content. The feature responsible for this effect works effectively without overprocessing the picture. Even on the medium setting it can noticeably reduce visible banding and unevenness without heavily blurring details. Upscaling itself also performs very well. Lower-resolution content is displayed cleanly, edges look natural, and the image is not overly sharpened. The UR8S simply copes very well with a weaker signal, and in this respect it is one of its most notable strengths.

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 smoothness of motion or dislike the characteristic stuttering of films recorded at 24 fps, the manufacturer has prepared a fairly extensive motion smoothing system. In the dedicated tab, we will find a slider for “Smoothness” that is responsible for eliminating stutter, and “Motion Blur Reduction,” which helps increase the sharpness of dynamic elements. The function works very well and granularly, meaning that each setting 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 multiples of film or television materials. With such an extensive set of options, every user will find their golden mean. In the picture, we present our choice, which is slight smoothing without the soap opera effect.

Motion is influenced not only by 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 especially VA panels that come close to the results of organic panels.

The UR8S is equipped with a panel with a native 180 Hz refresh rate, so right from the start it offers excellent motion handling. The panel itself performs really well here, although some limitations typical of VA panels are still visible. Motion blur is relatively minor for this type of screen, but with faster motion (especially on darker backgrounds) it can still be noticed, particularly when compared with the same image on OLED TVs.

The Philips OLED 809 television supports all technologies included in the HDMI 2.1 standard, and during our testing, each one activated without any problems. Therefore, we must state that this television is perfectly suited for all gamers, whether they are using a console or a computer. It is worth mentioning that the manufacturer has opted to implement the HGIG mode, which provides a great alternative to Dolby Vision, which unfortunately in the OLED809 is unplayable due to very high input lag.

A nod to gamers is also the inclusion of a dedicated GameBar, which allows for monitoring current gameplay parameters and quick changes to settings. We will also find a function to enable a crosshair, which will be very useful when shooting with 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 made for gaming. Especially since features such as VRR, ALLM, G-Sync, FreeSync, or HDR Dolby Vision gameplay will allow for an even greater immersion in their favourite title. Lastly, we will add that the only downside of the television in game mode is the artificial image sharpening, regardless of the settings, and it cannot be 'softened'.

In terms of gamer features the UR8S performs really well. The TV supports practically everything you can expect from a modern console or PC display. It offers ALLM, VRR and 4K at 120 Hz. There is also Dolby Vision in Game Mode, so when using, for example, the Xbox Series X you do not have to give up that HDR format. PC gamers get even more options. The panel can run at 4K at 180 Hz, and dropping to Full HD can raise the refresh rate to as much as 330 Hz. There is also a Game Bar that lets you quickly check key information and change gaming-related settings. The only clear omission is a correct implementation of HGiG. With it enabled the TV still alters HDR brightness mapping, so we do not get the effect intended by that standard. Aside from that, the UR8S is very well prepared for both consoles and a powerful PC.
