Philips PML9009 / 9019 / 9059 vs LG OLED C4

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 performance of the LG OLED C4 is impressive, firmly placing it in the higher tier. Most films exceed 700 nits, delivering a highly realistic image. While none surpass the 1,000-nit mark, the combination of these results with the TV’s infinite contrast and perfect blacks significantly enhances the visual experience. The final scene, with a full-screen flash of sunlight, is slightly less bright than the others but still maintains a solid level of brightness. Another highlight is the excellent DCI-P3 colour gamut coverage, which ensures incredibly vibrant colours. The HDR technology in the LG OLED C4 delivers exceptional colour and detail reproduction. The dynamic tone mapping feature optimises brightness levels, ensuring ideal light reproduction in every scene, even in the most demanding high-dynamic films.

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 mode on the tested television was "Filmmaker," which served as the basis for all evaluations. In terms of colour reproduction, this mode performed reasonably well; however, certain flaws significantly detracted from the overall viewing experience. The most fundamental issue was the white balance, which exhibited a noticeable dominance of red, skewing the image characteristics. This resulted in a pronounced yellow tint to whites and a general shift of all colours towards warmer tones.

The gamma, an equally crucial—if not more important—aspect, was notably lowered, leading to a marked reduction in contrast. Additionally, the television frequently lost detail at the start of the gamma curve. These issues were most apparent in SDR content.

When examining HDR materials, the same yellowing effect in the white balance was observed, as seen with SDR content. However, the EOTF curve, which replaces the gamma curve for HDR, was near perfect and left little room for criticism.

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.

As mentioned, LG televisions come with advanced tools to facilitate an accurate calibration process. By utilising these tools, we meticulously adjusted the image to align with the director’s original vision. Without overstating, the results were outstanding. Both SDR and HDR content now achieve a level of visual fidelity that reflects how films are intended to be seen.

Examining the colour accuracy on the "ColourChecker" palette reveals impressive results, with almost all colour errors falling below a delta of "1," aside from two minor exceptions. Post-calibration, the LG OLED C4 demonstrated a marked improvement in colour reproduction, particularly in SDR and HDR modes. Testing the TV after calibration highlighted its capacity for delivering exceptionally accurate colours, underlining the high calibre of this model. The LG C41LA offers a stunningly precise colour palette, sure to satisfy even the most discerning viewers.

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.

Let us revisit the function responsible for smooth gradation and consider its role in improving lower-quality materials. The default smoothing of tonal transitions, while decent, can be further enhanced. The feature includes a slider for adjusting its strength, and we recommend selecting the first option. This setting strikes a balance, offering excellent results without compromising important details through unnecessary blurring.

The image scaling on the LG C4 is commendable, though not entirely without flaws. By default, the image appears slightly sharper, though not to an intrusive degree. While jagged edges on elements like trees are occasionally visible, this issue is relatively minor compared to similar offerings from other manufacturers.

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 LG G4 supports a maximum refresh rate of 144 Hz, achievable only when connected to a high-performance PC. Otherwise, the television operates at a maximum of 120 Hz, the recommended setting for viewing sports or content with fast-paced motion. For those prioritising smooth image quality, LG has included a versatile motion smoothing feature called "TrueMotion." This function is split into two adjustable sliders: De-Blur, which sharpens moving images, and De-Judder, which reduces jitter. Both sliders offer a range of settings from 0 to 10, enabling users to fine-tune the motion smoothness to their preference.

The LG OLED C4 boasts an impressive average response time of less than 1 millisecond, as confirmed by our measurements. This results in exceptional image clarity, far surpassing LCD televisions, which often have response times of several milliseconds. This clarity is evident in tests like the "UFO Test," 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 C4, like nearly all OLED televisions from the manufacturer, excels in its compatibility with consoles and PCs. With the inclusion of four full-bandwidth HDMI 2.1 ports supporting 48 Gbps, the TV incorporates a range of features to enhance the gaming experience. Notably, it offers simultaneous support for FreeSync and G-Sync, making it an ideal choice for gamers using AMD or Nvidia graphics cards. For those seeking the best possible gaming quality, the integration of HDR Dolby Vision and HGIG mode is particularly impressive. HDR Dolby Vision operates with remarkably low input lag across all settings, ensuring smooth and responsive gameplay.

A standout feature in LG's televisions is the GameBar, which allows users to adjust settings in real-time without leaving the game. This includes options for customising the image for viewers with visual impairments, a thoughtful addition. Additionally, enabling VRR (Variable Refresh Rate) does not result in a loss of contrast—a benefit of the OLED panel's self-emissive technology, eliminating the need for conventional backlighting. While some slight flickering of grey tones may occur, this is a characteristic of VRR technology across all manufacturers.

In summary: The LG C4, like the brand's other OLED models equipped with high-refresh-rate panels and HDMI 2.1, provides a seamless and immersive gaming experience. For gamers demanding top-tier performance, this TV is an outstanding choice.
