Philips PML9009 / 9019 / 9059 vs LG 55 B4

The Philips PML9009 struggles to deliver the highest HDR performance. Scenes with effects around 550 nits don’t provide particularly impressive lighting, though the effects remain stable, an improvement over SDR materials. A notable exception is in Gemini Man, where a flashlight as the sole light source stands out. This is likely due to the absence of large dark areas and the relatively small size of the light source compared to scenes with larger, brighter elements like the sun. While the brightness results in HDR content aren’t quite strong enough to recommend this TV for productions utilising a wide colour gamut, it’s worth mentioning that the model does achieve decent coverage, reaching 93% of the DCI-P3 spectrum.

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.

During testing, the Philips PML9009 performed best in the factory "Filmmaker" mode, which we evaluated across both SDR and HDR content. A key characteristic observed in this mode is the EOTF curve’s behaviour in HDR content and gamma settings in SDR, designed to enhance image accuracy. However, the PML9009 presented noticeable issues, particularly with white balance, as a pronounced red dominance created a yellow tint across the entire image. This affected skin tones and white areas, with faces and whites appearing unnaturally warm. The colour shift was confirmed through the "ColourChecker" palette, where colours leaned towards warmer shades.

In the gamma analysis, responsible for image contrast, we noticed considerable inaccuracies early on. Our measured values spiked above the reference, causing dark scenes to lose detail and merge visually up to about 10% screen brightness. Following this, the values dropped below the target line, further degrading contrast—an area already challenging for this model.

In HDR content, the white balance remained similarly flawed, and the EOTF curve also restricted brightness levels, resulting in a dim, muted image. Colour inaccuracies were even more pronounced here, with lower luminance levels causing large deviations from accurate colours, which were clearly visible on the error graph, often exceeding acceptable limits. While aiming for cinematic quality, this mode ultimately fell short in delivering balanced colour and contrast fidelity.

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.

Philips has long provided sophisticated calibration tools, including 2-point and 20-point grayscale adjustments as well as an advanced CMS (Colour Management System). These allow users to make significant improvements, and even those less attentive to image quality will likely notice a positive difference post-calibration. Both SDR and HDR content benefit from this process, notably eliminating the prominent yellow tint caused by an overemphasis on red in the white balance.

For SDR content, although gamma adjustments don’t entirely resolve the loss of detail in dark areas, the overall improvements bring most content to an impressive standard, with minimal, hardly perceptible errors. Colour accuracy is notably enhanced, achieving nearly reference quality with low deltaE errors.

HDR content, however, remains somewhat limited due to the display’s lower brightness capability. While the white balance has largely been corrected, a slight blue tint can occasionally appear. The EOTF curve aligns very well, providing accurate geometry, though colour errors persist due to the limited luminance. This calibration offers a substantial improvement but may still fall short for viewers who expect high brightness levels in HDR.

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.

Given the impressive handling of tonal transitions by the Philips PML9009, one might expect similar success in the image scaling test. However, the results were less than stellar. When upscaling lower-quality images, like those from certain TV programmes or older films, the Philips algorithm tended to blur fine details noticeably, especially in intricate elements like fine branches or a model's hair.

On the other hand, the tonal transition performance remains noteworthy, with the TV offering several levels of smoothing. Even at the lowest setting, it effectively addresses non-smooth transitions in most materials, and crucially, it preserves the film grain effect, maintaining fidelity to the director's vision. However, it’s worth noting that some fine details may still appear slightly softened.

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.

The Philips PML9009 has a 120 Hz native refresh rate, a baseline standard for watching sports and an ideal setting for gaming on consoles or PCs. Philips includes an effective motion-enhancement system for users who want to reduce the stutter of 24 fps content or need fluid motion for fast-paced scenes, like in football matches. The dedicated "Smoothness" slider effectively mitigates stuttering, while "Motion Blur Reduction" enhances the sharpness of dynamic content. Each setting produces a noticeable difference, so users can tailor the motion effects to their preferences. Our recommended setup achieves a moderate smoothing effect, avoiding the exaggerated “soap opera” appearance.

Regarding pixel response time, VA panels like this generally fall short compared to OLED or even IPS panels, which can lead to a slight "black halo" trailing behind fast-moving objects. Although not a frequent issue with this TV, the effect can be seen in certain scenes.

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.

The Philips PML9009, with HDMI 2.1 ports supporting full bandwidth, is thoroughly equipped with gamer-focused features. Core functions like Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM) are included, as well as the additional perks of G-Sync and FreeSync compatibility and low-lag HDR Dolby Vision support. All these gaming features activate seamlessly, proving this model’s suitability for gaming. The TV’s HGIG mode, particularly beneficial for gaming, adjusts HDR effects to the television’s capabilities to avoid image dimming and blooming, an advantage given the still limited number of games supporting Dolby Vision.

For added convenience, the PML9009 has a GameBar menu, allowing in-game setting adjustments without needing to exit. This menu includes features like a crosshair option and black level correction, which can enhance the visibility of shadowed areas—ideal for competitive play.

Overall, the Philips PML9009 offers a comprehensive setup for gamers, supporting VRR, ALLM, G-Sync, FreeSync, and HDR Dolby Vision to deliver immersive, high-quality gaming experiences across a wide range of titles.

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.
