LG 55 B4 vs PHILPS PUS9060

The HDR brightness performance of the LG B4 is impressive, even though it doesn't surpass 1000 nits. Its luminance stability is consistently strong across various scenarios, delivering a reliable viewing experience. The only instance where the TV shows slight weakness is in scenes with large areas of bright white, which has long been a challenge for OLED technology. However, perfect contrast, deep blacks, and excellent brightness ensure a fully immersive HDR experience. Furthermore, the TV’s remarkable 99% coverage of the DCI-P3 colour gamut enhances its colour vibrancy, making images appear rich and visually striking. This level of colour accuracy and brightness balance firmly places the LG B4 among the top choices for HDR content.

The One is bright enough to enjoy movies recorded in HDR format. The average brightness of this model is about 500 nits, so we can count on a pleasant viewing experience for movies from streaming platforms without any issues. Of course, it could always be better, because when it comes to brightness, there is never too much for this type of content. Unfortunately, a disappointing surprise may be the DCI-P3 color gamut coverage offered by the PUS9060. Although the manufacturer boasts about using a QLED filter here (it’s actually PFS LED), it's hard to talk about any positive effects of its operation. 85% DCI-P3 color gamut coverage is definitely not a level to brag about in 2025 – especially in a television advertised as QLED.

The best factory preset offered by LG B4 is the "Filmmaker" mode, which we used throughout our testing. Straight out of the box, the TV delivered fairly accurate colour reproduction. However, the most significant issue in both SDR and HDR content was the white balance. In SDR, there was a noticeable red dominance, giving the image a distinct yellow tint, particularly evident in skin tones and whites. In HDR, this red hue persisted, but the lack of blue also introduced a greenish tint in certain scenes. Additionally, we observed some inconsistencies in grayscale and colour accuracy. Despite these shortcomings, the overall picture quality was still solid for most viewing scenarios.

We tested the PUS9060 in the best factory mode it employs – of course, we’re talking about movie mode. Unfortunately, the best in this case doesn’t mean good. The picture in this mode was distinctly yellowed and leaned towards orange tones. The white balance on this TV was definitely too warm, resulting in an artificial, somewhat "sun-kissed" look for the entire scene. This directly translated to significant color errors, which in the worst cases exceeded a delta E value of 6 – thus, they were visible to the naked eye. The situation was the opposite in HDR mode, where the picture became too blue and too cold in appearance. Additionally, there was a slight increase in brightness – the gamma curve and EOTF suggested that the TV slightly brightens the image, which was also evident in the comparison photo below.

LG B4 has long been known for offering advanced calibration tools, and it remains one of the few manufacturers that allows such in-depth image adjustments. Thanks to these tools, we calibrated the device to an exceptional standard. The result was incredibly low deltaE errors, considered at a reference level. Both SDR and HDR content now display exactly as the filmmaker intended. This level of precision is one of the reasons LG TVs are frequently used as preview monitors in graphic design and post-production studios.

Thanks to calibration in movie mode, we managed to completely eliminate the yellow-orange hue, which significantly improved the reception of the entire scene. The image has become much more visually pleasant, although it still falls short of reference settings. It may now appear slightly bluish, but it is still a significant improvement compared to the factory settings.

Unfortunately, we could not significantly improve the brightness characteristics, but that is more about the construction of the TV itself – the lack of local dimming limits the possibilities for precise brightness management. The PUS9060 simply cannot dynamically adjust luminance like more advanced models do. Nonetheless, after calibration, the overall reception is much more enjoyable, especially in film materials.

In this section, we will revisit the smooth transition function while also examining how the TV handles lower-quality content. As we’ve found, the setting responsible for smooth gradation is generally effective, though it does have its drawbacks. While the function works well in SDR content, it becomes less useful in HDR content. Even at the lowest setting, it can blur important details, so we advise against using it in such cases.

The image scaling on the LG B4 is assessed moderately positively. While there is no noticeable edge doubling, the image tends to be somewhat "soft." This can be adjusted by tweaking the sharpness slider to improve the clarity.

In the PUS9060, we find the latest version of the image processor called P5 Perfect Picture, which is designed to improve the picture - especially the imperfect ones. The TV features a distortion reduction function, which smooths out tonal transitions, that is, those "color joins" mentioned earlier. And this function does so very effectively - there is no strong color gradation, but unfortunately, it works aggressively enough that it sometimes dims desired elements, such as material textures or film grain. So this can be considered a compromise. We would not recommend using this function for movies, but for more casual content - such as YouTube or regular television - absolutely.

The P5 processor also improves the quality of lower resolution images, and it does this quite effectively. The test image with the model is very soft - sometimes even too much - but this can be easily adjusted with the sharpness slider to match personal preferences. It is also pleasing that the TV does not cut off edges in SD content - which unfortunately still happens in some TV models.

The maximum refresh rate on the LG B4 is 120 Hz, the bare minimum for those requiring high image fluidity. The manufacturer has equipped the TV with a multi-stage motion smoother called "TruMotion." This feature is split into two sliders: one controls the sharpness of moving images (De-Blur) and the other adjusts judder (De-Judder). Both sliders can be set between 0 and 10, with each level affecting the smoothness, so users can easily find their preferred setting.

The LG OLED B4 panel boasts an impressive average response time of 0.1 ms (based on our measurements), delivering an exceptionally clear image that surpasses the capabilities of LCD TVs, which often have response times of several milliseconds. This is particularly noticeable in the "UFO Test" images, where no trailing blur is visible behind moving objects.

PHILIPS PUS9060 is equipped with a 4K display with a 144 Hz refresh rate, so we can confidently say that it is suitable for both watching sports and playing games. And indeed, it is. But what about movies that are most often recorded at 24 frames? Like most of the TVs we tested with a refresh rate of 120 Hz and higher, the PUS9060 offers two sliders in the motion smoothness options. The “Smoothness” slider allows you to adjust the effect in movies – you can set the image to be smoother, resembling a theatrical effect (higher settings), or more cinematic, with a slight “jump” in frame rate (lower settings). Additionally, there is a function called "Motion Blur Reduction," which reduces blurring – and this is a very useful feature, especially when watching sports.

The LG B4 has four full HDMI 2.1 ports, each providing 48Gbps bandwidth. This ensures smooth activation of all relevant features without issues, making the television highly suitable for gaming. With its low input lag and extensive functionality, including well-implemented HGIG mode and Dolby Vision gaming with low latency, the B4 is a strong contender for gamers who demand high quality.

A standout feature is GameBar, which allows for on-the-fly adjustments without interrupting gameplay, as well as image adaptations for those with visual impairments. Another key point is that when VRR technology is enabled, the television maintains its contrast, thanks to the OLED panel's structure, though slight flickering in grey shades is to be expected.

In conclusion, the LG B4 is an ideal choice for gamers, seamlessly combining high performance with excellent gaming features. Its 120Hz panel and HDMI 2.1 ports make it a standout option for those seeking top-tier gaming experiences.

The PHILIPS PUS9060 is a true gaming monster – it has practically everything you could expect from a modern gaming television. It features VRR, ALLM, and also includes HGiG implementation, which helps set up HDR in games as the developers intended. The TV supports every possible resolution at 120 Hz, including 1080p, 1440p, and full 4K – so regardless of whether you’re playing on Xbox, PS5, or a PC, everything works as it should. There is also a simple Game Bar, which is a special menu for gamers that allows you to quickly check if the ALLM mode is indeed functioning in the lowest latency setting.

And of course – Ambilight TV. Let's be honest – without LEDs on the back, it’s not a true gaming device. 😉 The multicolored backlighting can really enhance the atmosphere, especially in the evening. It may not be to everyone's taste, but younger gamers will be thrilled – because it simply looks impressive.
