Philips The One (PUS8959 / PUS8919 / PUS8909 / PUS8949 vs LG 55 B4

The luminance graph for Philips PUS8959 shows that the television can achieve around 550 nits of brightness, which can be considered a satisfactory level. Such brightness allows you to feel the effects of HDR, which stand out particularly in more demanding scenes. In the tested patterns, the television performed quite well, even in challenging sequences like those from "Sicario 2". Due to the lack of local dimming, the television does not dim small bright elements, and they shine at the full "power" of the television but at the cost of silvery blacks, which we mentioned in the paragraph about black levels. It’s also worth praising Philips PUS8959 for its good coverage of the DCI-P3 colour palette, which is around 94.5%. This ensures that the colours are vivid and close to the creators' intentions, which further enhances the quality of HDR effects and the experience of watching high dynamic range content.

The brightness results in HDR materials LG B4 are very good. It is true that none of them exceed 1000 nits, although the luminance stability is excellent and looks practically the same in every scenario. The only moment where the tested television performs worse is the last scene, although this should not come as a surprise. Large frames filled with a lot of white have always been, and will likely continue to be, somewhat of a weakness for OLED televisions. However, the combination of perfect contrast, black levels, and brightness in the LG B4 allows for a full spectrum of the HDR effect. Additionally, the incredibly high coverage of the DCI-P3 colour gamut, which reached 99%, deserves recognition. As a result, colours look incredibly vibrant and stunning.

The television Philips PUS8959 has been tested in the best, theoretically most precise picture mode – Filmmaker. Although the name suggests film quality, it unfortunately falls short of perfection. The biggest issue in this mode is the white balance, both in HD and 4K content. It is characterised by a significant dominance of the red colour and drops in the green levels, resulting in unnatural colour reproduction. For example, white elements of the image have a noticeable pink hue, and the green is less intense, which diminishes the overall naturalness and colour balance. The ColorChecker test confirms these errors – it is clearly visible how the colour samples "deviate" from the proper values, which can best be observed on the sample squares that should precisely reproduce the colours. The lack of accuracy in this regard affects the realism and fidelity of the image, which is particularly undesirable in Filmmaker mode.

As for the brightness characteristics, the gamma graph resembles a roller coaster – with small elements displayed on the screen, the brightness is excessive, causing details to become overly exposed. Conversely, at higher gamma values, the image loses contrast and becomes too dark, making the whole appear lacking in dynamism. Similar problems can be observed in the EOTF characteristics – the television is unable to accurately reproduce the brightness levels, negatively impacting the overall picture quality.

The best factory mode prepared by the manufacturer is "Filmmaker," and we used it throughout the entire testing procedure. We must admit that the unit we received straight out of the box had quite decent colour reproduction. The biggest issue in both SDR and HDR content turned out to be white balance. In the former, there was a strong dominance of red, resulting in a noticeable yellow tint in the displayed image, particularly evident on skin tones and whites. In high-quality materials, this colour was also pronounced, but due to a lack of blue, there were also signs of green visible. Besides these shortcomings, we also encountered issues with greyscale and the colours themselves.

After calibration, the Philips PUS8959 shows a significant improvement in colour reproduction, especially in HD content. The white balance is exceptionally even, and the Delta E error values are below 1, which can be regarded as an outstanding result. Additionally, the gamma, which affects brightness in lower quality materials, performs very well, maintaining a stable level at 2.4, leading to an appropriate balance between bright and dark areas of the image.

When it comes to 4K HDR materials, there is also a noticeable improvement. The white balance, although not as perfect as in HD content, no longer suffers from excessive red exposure, making the image appear more natural and harmonious. Unfortunately, regarding the EOTF characteristic, it’s difficult to speak of any significant improvement, which stems from the structural limitations of the television that prevent substantial enhancement in this aspect.

Nevertheless, overall, it looks much better after calibration, making the Philips PUS8959 one of those televisions where it's truly worth investing time in precise calibration to achieve satisfactory image quality.

LG B4 has been providing very advanced calibration tools in its TVs for years. We can even say that as the only manufacturer on the market, it allows for such deep intervention in image adjustment. Thanks to these, we were able to calibrate the device so well. The evidence of this is the extremely low deltaE errors, which can be said to stand at a reference level. Both SDR and HDR materials now look exactly as the film director intended. It is no coincidence that TVs of this brand are most often used as preview screens for various graphic or post-production studios.

When it comes to smoothing tonal transitions, the "Distortion Reduction" function in the minimum position performs quite well, effectively smoothing tonal transitions without excessive impact on other elements of the image. In testing, I did not notice that the reduction negatively affected the structure of the image, such as film grain or details of objects – everything remains in its place, which is a big plus for users who value the natural look of film material.

As for digital processing, the image looks pretty good, although it features very softened contours, giving it an almost "leafy" character. This effect may evoke mixed feelings – some users will appreciate the fluidity and delicacy of this type of presentation, while others may find it too gentle, losing detail. It is a matter of individual preference, but it must be admitted that Philips PUS8959 provides quite subtle yet effective tools for improving tonal transitions without excessive interference with the natural character of the image.

In this paragraph, we will take another look at the tonal transition smoothing feature, but we will also check how the TV handles lower quality material. As we have managed to check, the setting responsible for smooth gradation works quite effectively, although it has its weaker moments. While the feature works well with SDR content, it becomes less useful with HDR content. Even at the lowest of options, it blurs essential details, so we advise against using it.

The image scaling on LG B4 is rated fairly moderately positively. Although there is no edge splitting, the image itself is naturally "soft". We can change this by adjusting the sharpness slider.

Philips PUS8959 TV is equipped with a 120 Hz panel, which should satisfy more demanding users, especially those who love watching dynamic sports broadcasts or playing games. Such a high refresh rate allows for significantly smoother images, being a key aspect during dynamic scenes and fast actions.

For those who prefer watching movies, the TV offers an additional motion smoother that allows adjustment of the frame rate according to personal preferences. The Philips PUS8959 features a 10-step adjustment for functions called "Smoothness" and "Motion Blur Reduction". The "Smoothness" function increases the number of frames through interpolation, making movement on the screen smoother, reminiscent of the so-called "soap opera effect". Meanwhile, "Motion Blur Reduction" focuses on minimising streaking and improving motion clarity, which is particularly noticeable in dynamic sequences such as action scenes or fast sports shots.

The maximum refresh rate we can set on the LG B4 is 120 Hz. This is the absolute minimum for those who require high image smoothness. The manufacturer has implemented a multi-level motion smoother called "TruMotion". It has been divided into two separate sliders that adjust the sharpness of moving images (De-Blur) and stuttering (De-Judder). Both sliders can be set in the range from 0 to 10, with each level affecting the degree of smoothness, so everyone can find their sweet spot.

The LG OLED B4 panel features an average response time of 0.1 ms (which directly results from our measurements), allowing for an incredibly clear image, unattainable for LCD TVs, which have response times of even several milliseconds. This can be clearly seen in images from the "UFO Test", showing no trace of blur trailing behind the object.

Philips PUS8959 is a television that will surely please gaming enthusiasts. It supports most modern technologies useful during gameplay, such as HGiG, allowing for better representation of HDR effects in games. As a result, the image is more aligned with what the game developers intended to achieve.

The television also supports displaying images at 120 Hz, ensuring smoothness and dynamism, particularly important during action games and sports broadcasts. The Game Bar feature provides quick access to game settings, making it easier to adjust the image according to user preferences without interrupting gameplay.

Unfortunately, the Dolby Vision mode does not offer low input lag, which may be noticeable during dynamic scenes. Nevertheless, thanks to the HGiG feature and high refresh rate, the Philips PUS8959 remains an attractive choice for gamers, offering good image quality and suitable smoothness during gameplay.

The LG B4 television is equipped with four full-fledged HDMI 2.1 ports with a full bandwidth of 48Gbps. All functions corresponding to this standard activated without any issues, and throughout the entire testing procedure, they caused no problems. The combination of such extensive functionality and low input lags leads us to say that the tested television is truly designed for gaming. This is not surprising, considering that the manufacturer has always placed great emphasis on this. Therefore, we can enjoy both a properly implemented HGIG mode and gameplay in Dolby Vision with low latency. Such a tandem will surely attract the attention of all passionate gamers for whom quality is the most important.

A standard feature in televisions from the Korean manufacturer is also the implementation of GameBar, allowing for quick adjustments of settings "on the fly," without the need to exit the game. It also enables image adjustments for individuals with visual impairments, which is an extremely nice touch. Another important piece of information is that when the VRR technology is turned on, we will not experience a drop in contrast. This is, of course, due to the construction of the panel and the lack of conventional backlighting. However, it is normal for shades of grey to flicker slightly, although this is a characteristic feature of this function regardless of the manufacturer and the television.

In summary: The LG B4, like all OLEDs from the manufacturer equipped with 120Hz panels and HDMI 2.1 ports, creates a harmonious whole with the console. In practice, it is a complete television, and if we expect the highest possible efficiency in gaming, the B4 will be the ideal choice.
