Philips OLED909 vs Philips OLED820

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.

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 the 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 incredible precision, as this is the brightness range in which modern productions are mastered. Of course, there are situations where even the OLED820 has to compromise. Full-screen scenes flooded with white, like those in the film The Meg, can drop brightness to 400–500 nits, which clearly diminishes the effect. This is a characteristic of OLED technology that has not yet been fully eliminated. Despite this limitation, it's hard not to appreciate the HDR in this model – high luminance and a wide coverage of the DCI-P3 colour palette at 99% make the image look simply fantastic.

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.

The colour reproduction in the factory settings really surprised us, and in a positive way. 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, although there was a slight deficiency in the blue hue, which sometimes gave the image a slightly yellowish tint. However, this is not a drawback that particularly interferes with everyday viewing. A bigger problem arose with the brightness characteristics. The gamma chart clearly deviated from the ideal, as the line was 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.

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.

After calibration, both the Filmmaker mode and the gaming mode improved quite a bit. A slight adjustment of the white balance and enhancement of the brightness characteristics yielded excellent results with SDR content – the image looked nearly perfect, natural, and very close to the reference. For HDR material, the situation was similar; the colours looked fantastic, and it was hard to find fault with anything. However, we did notice a certain characteristic, which we had already pointed out when comparing scenes from the film Billy Lynn. The analysis of the EOTF curve showed that the TV has a slight tendency to dim details in the blacks, meaning that the darkest parts are not always displayed exactly as the director intended. Nevertheless, the effect after calibration is superb, and the OLED820 is emerging as one of the more interesting screens in its class. A little bit of fine-tuning is all that’s needed, and there’s really nothing to worry about.

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.

Fortunately, the earlier effects of the mentioned posterisation can be quite effectively mitigated. The "distortion reduction" feature set to medium handles unwanted colour banding well, improving the smoothness of tonal transitions. It does sometimes work a bit too aggressively and smooths out some details – such as the minor imperfections of the actors’ skin – but despite that, it can be considered worth using without major compromises. The upscaling in the OLED820 also performs well. The test image with the model is exceptionally soft, sometimes perhaps too much, although this can be remedied with a slight increase in sharpness in the picture menu – that's a matter of individual preference. The absence of overscan issues with very low-resolution content is also commendable, allowing us to not worry about the image being unnecessarily cropped.

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.

Motion fluidity 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 will mainly benefit PC gamers, but even with standard TV sources or consoles, where it operates at 120 Hz, motion is fast, sharp, and simultaneously smooth, without any signs of smearing. This is thanks to the remarkable response time between pixels, which ensures the image maintains clarity in every dynamic scene. The manufacturer has also added their own smoothness enhancer called "Motion Style." In the menu, we find two sliders – the first, responsible for smoothness, allows for the adjustment of the number of artificially added frames in films. This way, we can choose a raw, cinematic character with clearly visible film frames 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.

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.

The Philips OLED820 is one of the most comprehensive TVs for gamers. Onboard, we find practically everything one could expect: two HDMI 2.1 ports with full bandwidth of 48 Gbps (shame there aren't four), Variable Refresh Rate (VRR), Auto Low Latency Mode (ALLM), support for Dolby Vision in games, and a good implementation of the HGiG mode. The TV also handles lower resolutions at 120 Hz without issue, so you can count on great flexibility when choosing different picture modes on your console. Philips also adds a Game Bar – a panel that allows you to change picture modes, add a crosshair, or preview parameters. Although it looks a bit clunky and is less refined than its competitors, it gets the job done. In practice, therefore, the OLED820, in addition to a full set of four HDMI 2.1 connections, offers almost everything a gamer could need.
