Philips OLED909 vs Philips OLED820

The Philips OLED909 impresses with the quality of its HDR effect, 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 matrix, also used in models like the Panasonic Z95A and LG G4, plays a key role here, allowing for exceptionally bright and detailed reproduction of dynamic scenes. However, it's worth noting that in the most demanding scene from the movie The Meg, the brightness drops to around 700 nits. This is a typical phenomenon in OLED technology, where intensely bright full-screen images cause a limitation of luminance. Nevertheless, the HDR effect still looks very good, and the television performs better than most competitors under similar conditions. The wide color gamut coverage also deserves praise. The OLED909 offers 95% coverage of DCI-P3, ensuring the television can display vivid and realistic colors.

When it comes to HDR quality, the Philips OLED820 uses the same class of WOLED panel that we find in its biggest competitors – LG C5 or Samsung S90F. This means we can count on truly solid performance. This year, mid-range OLED panels are capable of exceeding the threshold of a thousand nits, and the model tested reaches around 1300 nits in some films. This is an outstanding result that allows for an extremely precise depiction of the director's vision, as contemporary productions are mastered in such brightness ranges. Of course, there are situations where even the OLED820 has to compromise. Full-screen scenes flooded with white, like those in the movie The Meg, can drop brightness to 400–500 nits, which clearly weakens the effect. This is a characteristic of OLED technology that has not yet been fully eliminated. Despite this limitation, it is hard not to appreciate the HDR in this model – high luminance and wide coverage of the DCI-P3 color gamut at 99% make the picture simply look great.

Like other televisions, the Philips OLED909 has been tested for color reproduction in factory modes. The best mode turned out to be Filmmaker Mode, but despite its name, it is not free of flaws.

The biggest problem is the white balance. Both in HD and 4K HDR content, there is a noticeable dominance of green and red shades, which causes a distinct yellowing of the screen. This effect is particularly visible in test materials, for example in the scene with Tom Cruise in the foreground, where the difference compared to the calibrated image is very clear.

Regarding brightness characteristics, the gamma in HD materials was boosted too much - it was below the reference value of 2.4, which gave the image a "milky" filter and affected the overall clarity. In the case of 4K HDR content, we noticed the opposite phenomenon – there is a clear drop at the beginning of the EOTF curve, indicating problems with reproducing the smallest details in dark scenes. Although the Filmmaker mode offers acceptable quality, noticeable errors in white balance and brightness characteristics show that the television requires additional calibration to fully reveal its potential in color reproduction.

The color reproduction in the factory settings really surprised us, and positively so. The Philips OLED820, switched to Filmmaker mode, immediately showed that it was quite well tuned in terms of color. The white balance was relatively accurate, though with a slight lack in the blue hue, which sometimes gave the image a slightly yellowish tint. However, this is not a flaw that particularly interferes with everyday viewing. A larger problem arose with the brightness characteristic. The gamma chart clearly deviated from the ideal, with the line being below the expected values, causing the image to be overly brightened, and the colors 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, which significantly improves its quality. After calibrating the Filmmaker Mode, the television presents a much more natural color reproduction. The white balance after calibration looks very good. Although we noticed slight deviations in the blue hue in HD content, the errors fall within acceptable limits, and the image looks much better than in factory settings. The brightness characteristics, including gamma and EOTF, have also been distinctly improved. The television no longer has issues with excessive brightening or darkening of the image. Both dark and light details are now rendered correctly, making the image look very good in every scene. After calibration, the Filmmaker mode in the Philips OLED909 offers excellent image quality that will meet the expectations of even the more demanding users. The calibration fully utilizes the potential of this model.

After calibration, both the Filmmaker mode and the game mode gained quite a lot. A slight adjustment of the white balance and an improvement in brightness characteristics resulted in excellent outcomes for SDR content – the image looked almost perfect, natural and very close to the reference. In the case of HDR materials, the situation was similar; the colors looked stunning and it was hard to find anything to criticize. However, we noticed a certain feature that we had already pointed out when comparing scenes from the movie Billy Lynn. An analysis of the EOTF curve revealed that the television has a slight tendency to dim details in the blacks, which means that the darkest sections are not always displayed exactly as the director intended. Nevertheless, the effect after calibration is remarkable, and the OLED820 stands out as one of the more interesting screens in its class. It just needs a little bit of fine-tuning, and there's really nothing to be afraid of.

Philips OLED909 offers a distortion reduction feature aimed at smoothing tonal transitions. Unfortunately, the effectiveness of this feature leaves much to be desired. Setting it to "Medium" yields some results, but it comes with the risk of blurring essential details in the image. For this reason, we do not recommend using this option unless you are focused on mitigating visible artifacts at the expense of detail.

When it comes to image scaling, the television presents a very pliable image, which may appeal to viewers who prefer a softer image. Those expecting sharper clarity will also find a solution, as image scaling can be adjusted according to individual preferences in the settings.

Fortunately, the earlier effects of the aforementioned posterization can be quite effectively mitigated. The "distortion reduction" feature set to medium handles unwanted color banding, improving the smoothness of tonal transitions. It does happen, however, that it works a bit too aggressively and smooths out some details – such as minor skin imperfections of the actors – but despite this, 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 even too much so, although this can be alleviated by slightly increasing the sharpness in the picture menu – it’s a matter of personal preference. The lack of overscan issues with very low-resolution content is also commendable, meaning we don't have to worry that the image will be unnecessarily cropped.

The Philips OLED909 with a 144 Hz panel offers excellent image fluidity, which should satisfy both movie lovers and gamers. Additionally, the television is equipped with a smoothing feature called "Motion Style," which allows precise adjustment of image fluidity to personal preferences. In the settings, we find two sliders: "Fluidity," which regulates the fluidity of motion in movies, and "Motion Blur Reduction," which helps eliminate minor artifacts and distortions in dynamic scenes. This feature works well, making even fast movements on the screen 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 television sources or consoles, where 120 Hz is used, the motion is fast, sharp, and simultaneously smooth, without traces of ghosting. This is thanks to the outstanding response time between pixels, which ensures the image retains clarity in every dynamic scene. The manufacturer has also added its own smoothing feature called "Motion Style." In the menu, we find two sliders – the first, responsible for fluidity, allows us to adjust the amount of artificially added frames in movies. This way, we can choose a raw, cinematic character with a clearly visible film frame or a more theatrical image with smooth motion. The second slider is for reducing blurring, especially useful in sports broadcasts. Here, we definitely recommend setting it to the maximum value, as the effect is truly excellent.

The Philips OLED909 is a television that meets practically all the requirements of gamers. Equipped with ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and support for Dolby Vision, it guarantees excellent gaming experiences. Additionally, the television offers very low input lag, ensuring that the response to player movements is instantaneous, which will be especially appreciated by fans of dynamic games.

The television easily supports any resolution at 120 Hz, and even higher refresh rates. The HGiG feature, responsible for the correct display of HDR content in games, works as it should, making the image in game mode balanced and tailored to the guidelines of console manufacturers.

The OLED909 also includes a Game Bar feature that allows for quick previewing and changing of game-related settings. Although the interface of this solution may seem less visually appealing than that of competitors, it serves its purpose well by offering all the most important options in one place.

Philips OLED820 is one of the most complete televisions for gamers. It practically has everything you could expect: two HDMI 2.1 ports with full bandwidth of 48 Gbps (too bad there aren't four), variable refresh rate VRR, automatic game mode ALLM, support for Dolby Vision in games, and a good implementation of the HGiG mode. The television also handles lower resolutions at 120 Hz without any issues, so you can count on great flexibility when choosing different picture modes on the console. Philips also adds Game Bar – a panel that allows you to change picture modes, add a crosshair, or view parameters. Although it looks quite clunky and is less polished than that of the competition, it serves its purpose. In practice, therefore, the OLED820, besides having a full set of four HDMI 2.1 ports, offers almost everything a gamer might need.
