Philips OLED909 vs Hisense U7S Pro

Philips OLED909 impresses with its HDR effect quality, achieving up to 1500 nits of peak brightness in tested scenes. This is an excellent result, placing this television among the best OLED models on the market. The MLA panel, also used in models like the Panasonic Z95A and LG G4, plays a crucial role here, allowing for exceptionally bright and detailed reproduction of dynamic scenes. However, it is worth noting that in the most demanding scene from the film The Meg, brightness drops to around 700 nits. This is a typical phenomenon in OLED technology, where intensely bright full-screen images cause a reduction in luminance. Nevertheless, the HDR effect still looks very good, and the television performs better than most competitors under similar conditions. The wide colour gamut coverage also deserves praise. The OLED909 offers 95% coverage of DCI-P3, ensuring that the television guarantees the ability to display vibrant and realistic colours.

Let's start with the fact that the U7S Pro is an impressively bright TV. In calibrated mode our test equipment recorded a staggering 2200 nits of peak brightness. That's an excellent result, especially given that this model is positioned more as a mid-range set.

As we know, peak brightness on test patterns is one thing, and real film scenes are another. Unfortunately, in real-world footage the backlight output drops noticeably. In the most demanding moments the TV can still exceed 1000 nits, which is still a great result and sits well within the HDR mastering standards for most films, but the real challenge comes from aggressively tuned local dimming algorithms. Because of them, small bright details, like stars or the moon in a night sky, are noticeably dimmed. The TV seems determined to preserve deep blacks, which is understandable, but sadly this comes at the expense of dynamic range and the overall HDR punch.

Colour reproduction is worth praising. The new U7S Pro is a QLED design that provides very wide colour gamut coverage. Unlike last year's model (U7Q Pro), this year's variant is a genuine QLED rather than a solution based on a PFS filter. As a result, colour saturation has clearly increased, and coverage of the demanding BT.2020 colour space has exceeded 81%.

Like other TVs, the Philips OLED909 has been tested for colour reproduction in factory modes. The best mode was found to be Filmmaker Mode; however, despite its name, it is not without faults.

The biggest problem is the white balance. In both HD and 4K HDR content, there is a noticeable dominance of green and red hues, resulting in a clear yellow tint on the screen. This effect is particularly visible in test materials, for example, in a scene with Tom Cruise in the foreground, where the difference compared to a calibrated image is very clear.

As for the brightness characteristic, in HD materials, the gamma was excessively boosted - it was below the reference value of 2.4, giving the image a “milky” filter and impacting overall clarity. For 4K HDR content, we observed the opposite phenomenon – at the beginning of the EOTF curve, there is a noticeable drop, indicating issues with reproducing the smallest details in dark scenes. Although Filmmaker mode offers acceptable quality, noticeable errors in white balance and brightness characteristics show that the TV requires additional calibration to fully realise its potential in colour reproduction.

We tested the U7S Pro, as we always do, in the best factory-tuned picture mode, Filmmaker Mode. The displayed colours can be judged in two ways. The most disappointing was the profile intended for SDR viewing, i.e. classic TV, YouTube and other less demanding content. The image there had a distinct yellow cast, which proved to be a direct result of an incorrectly set white balance. As our charts show, this involved a huge deficiency of the blue component, which drastically affected the overall colour temperature. You can see this clearly on the ColorChecker charts and on the colour palette graphs themselves, where most samples drifted towards yellow. Fortunately, the factory HDR mode performed much better; there the colour errors hovered around a Delta E of 3, which is a really solid result.

Philips OLED909 offers tools for image calibration, significantly improving its quality. After calibrating the Filmmaker Mode, the television displays a much more natural colour reproduction. The white balance after calibration looks very good. Although we noticed slight blue tint deviations in HD content, the errors fall within acceptable limits, and the picture is significantly better than in factory settings. The brightness characteristics, including gamma and EOTF, have also been clearly improved. The television no longer has issues with excessive brightening or dimming of the image. Both dark and light details are now rendered correctly, making the picture look very good in every scene. After calibration, Filmmaker Mode on the Philips OLED909 offers excellent picture quality that will meet the expectations of even the more demanding users. The calibration fully utilises the potential of this model.

We do know, however, that the company Hisense is capable of much more – as previous generations have proven – which is why we simply couldn’t leave the factory flaws of the U7S Pro model unaddressed in everyday content. As always in such cases, we had the television undergo professional calibration. The conclusions? This process brought about a colossal change. After manually adjusting the white balance and compensating for deficiencies in the blue component, the annoying yellow tint disappeared as if by magic. White became naturally clean, and skin tones gained the proper, healthy hue. Importantly, the calibration not only tamed the capricious SDR mode but also maximised the potential of the panel, reducing average colour reproduction errors to values nearly imperceptible to the human eye. The only thing we need to criticise after the whole process is the very nature of the Mini-LED backlighting and its specific interaction with the HDR signal. The aggressively tuned local dimming algorithms significantly interfere with the EOTF brightness curve. As a result, the backlighting doesn’t always work perfectly with the creator’s intent – depending on the scene being watched, the curve can noticeably run either above or below the reference, occasionally disrupting the ideal dynamic of HDR images.

Philips OLED909 offers a distortion reduction feature designed to smooth tonal transitions. Unfortunately, the effectiveness of this feature leaves much to be desired. Setting it to "Medium" achieves some effects, but it comes with the risk of blurring important details in the image. For this reason, we do not recommend using this option unless you are looking to soften visible artifacts at the expense of detail.

As for image scaling, the TV presents a very pliable image, which may appeal to viewers who prefer a softer picture. Those expecting sharper clarity will also find a solution, as image scaling can be adjusted to individual preferences in the settings.

The digital processing of lower-quality signals is at a very high level here, and that's all thanks to the MediaTek Pentonic 800 processor used in the U7S Pro. The upscaling itself also performs well, meaning the TV's ability to upscale lower-resolution signals to 4K is impressive. We didn't notice any unnatural, overly sharp contours on the screen, and our test image of the model simply looked attractive.

The Philips OLED909 with a 144 Hz panel offers excellent image fluidity, which should satisfy both movie lovers and gamers. Additionally, the TV is equipped with a motion smoothing feature called "Motion Style," which allows for precise adjustment of image fluidity according to personal preferences. In the settings, we find two sliders: "Fluidity," which adjusts the smoothness of motion in films, and "Motion Blur Reduction," which helps eliminate minor artifacts and distortions in dynamic scenes. This feature works well, ensuring that even quick movements on the screen are clear and readable.

The Hisense U7S Pro uses a panel with a maximum refresh rate of 165 Hz at 4K, and in gaming mode it can even hit 330 Hz at Full HD. However, it's worth remembering that these top figures don't mean much in everyday use, because most content still runs at a maximum of 120 Hz (for example when playing on a console). Even so, the TV handles motion quite well and performs respectably for an LCD design.

There isn't much to fault when it comes to smoothness. In the menu you'll find a motion smoothing feature called "Motion Enhancement", which hides two sliders: blur reduction and judder reduction. They let you manually tune the smoothing, which works well for both films and sport, effectively improving the raw TV signal.

Philips OLED909 is a TV that meets practically all the requirements of gamers. Equipped with ALLM (automatic low latency mode), VRR (variable refresh rate), and support for Dolby Vision, it guarantees an excellent gaming experience. Additionally, the TV offers very low input lag, ensuring that the response to player movements is instantaneous, which fans of dynamic games will particularly appreciate.

The TV effortlessly supports any resolution at 120 Hz, and even higher refresh rates. The HGiG function, responsible for correctly displaying HDR content in games, works as it should, making the picture in game mode balanced and aligned with console manufacturers' guidelines.

The OLED909 is also equipped with a Game Bar feature, which allows for quick preview and adjustment of gaming settings. Although the interface of this solution seems less visually appealing than that of competitors, it serves its purpose by offering all the essential options in one place.

If you're planning to connect a console or PC to the U7S Pro, you'll be more than pleased – this TV is great gear for gamers. Hisense hasn't held back, featuring 4 HDMI 2.1 ports with full bandwidth of 48 Gbps. So you don't have to juggle cables, as each port will handle the full suite of features. We have an automatic game mode (ALLM) and VRR, which operates over a wide range from 48 Hz to a whopping 330 Hz. Of course, that 330 Hz is currently just a gimmick for owners of powerful PCs, as consoles will cap at 120 Hz, but it's good to have that headroom for the future. The Game Bar also works really well when gaming. It's a handy menu bar for gamers, where you can quickly change the picture mode, turn on a crosshair in the middle of the screen, and even switch the display aspect ratio to ultra-wide, which PC simulation fans will appreciate. The only downside worth noting is the incorrect implementation of the HGiG format in games. The issue is that the TV ignores instructions from the console regarding the image generated in HDR10 and constantly butts in, trying to "enhance" the image in its own way. This makes proper HDR configuration in the console menu (where brightness is set on the logo/checkerboard) a bit more challenging.
