Philips PML8709 is a model that stands out in the offering of the Chinese-Dutch manufacturer due to its unconventionality. Instead of the classic operating system from Philips - TitanOS, we find here the already known Google TV, which provides extensive customization options and access to a rich library of applications. This is a television that, on one hand, tempts with very good contrast, and on the other – surprises with several unusual design decisions. When it comes to image quality, the PML8709 offers very good contrast, which, combined with wide color gamut coverage, ensures excellent color reproduction – especially after calibration. Despite the 60 Hz panel, the television also performs well in occasional gaming thanks to support for features such as ALLM, VRR, and a low input lag of around 13 ms. On the other hand, Philips has stripped this model of one of the biggest advantages of its televisions – the Ambilight system. This is a surprising decision that may disappoint many fans of the brand. Another weak point is performance in HDR – despite promising contrast results, the television performs average in this category. Maximum brightness and issues with detail in brighter scenes give the impression that something has evidently gone wrong in the implementation of this feature. The Philips PML8709 is a television full of contrasts. On one hand, it offers solid black quality and interesting solutions for gamers, on the other – some limitations, such as the lack of Ambilight or average brightness, mean that it is not a model without flaws. It is a good choice for those who appreciate the versatility of Google TV and are looking for a television for everyday use.

The LG OLED C4, as the name implies, utilises an organic matrix developed in-house, making it one of the most recognisable series on the market. With over 10 years of experience producing self-emissive panels, LG has continually refined its designs, and the 2024 models are the pinnacle of this progress. An OLED screen ensures flawless contrast and black levels, immersing viewers in the director’s vision. OLED technology stands out for its lack of traditional backlighting, instead relying on current flowing through organic pixels. This design allows for precise image control, eliminating issues like dimming of fine details or halo/blooming effects.

In our test scenes, two standout features were immediately apparent: perfect light separation and an abundance of detail in "The Revenant." Crucially, the C4 displayed the distinct green tint some televisions attempt to correct, without issues. The LG OLED C4 excels in delivering exceptional contrast, resulting in incredible depth and richness. Test results confirm that the black levels are flawless, particularly in high-contrast scenes. Ultimately, the LG C4 offers an unmatched contrast ratio, delivering a visually stunning experience whether watching movies or gaming.

The model name 8709 "PML" refers to Philips mini-LED technology, but can we really call its backlighting that? In the 65-inch version, we counted only 96 local dimming zones. For mini-LED standards, this number seems too low, raising questions about whether we are actually dealing with a full-fledged mini-LED here. However, if we look at the quality of black, the TV performs quite well. On the first two test screens, as well as in less demanding scenes, the image is quite decent – blacks are deep and the contrast is satisfactory. Problems start to arise in more complicated scenes, such as the last three test screens, where small light elements appear on the screen. The local dimming algorithm seems to "get lost," unable to decide whether to brighten or darken a certain area. The result is visible errors – reduced black quality and unevenness of the image. An example of the local dimming zones in action can be seen in a scene from the movie Sicario 2. You can see how the dimming zones try to reproduce details, but at the same time it leads to slight lightening around the helicopter lights. Nevertheless, despite these shortcomings, the blacks in the Philips PML8709 perform quite well, especially considering its price class.

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.

Looking at the contrast results, we expected that the algorithms responsible for the zones in the Philips PML8709 would be at least decent. However, what we encountered during testing is hard to explain. The maximum brightness we were able to achieve was only 350 nits, which is definitely too low to fully enjoy HDR effects. In practice, the TV barely stands out against an average SDR. The situation becomes even more surprising in the case of test scenes, such as the second one from the movie Life of Pi or Sicario 2. Small light elements reach only 120 nits there, making them practically invisible. Such a level of brightness is completely inadequate to modern HDR standards and significantly diminishes the viewing experience of high-quality content. The only bright spot in this category is the very good coverage of wide color gamuts – 97% DCI-P3 and 83% BT.2020. This ensures that colors are saturated and well reproduced, which can improve the overall viewing experience of HDR materials, even if just a little. However, the lack of appropriate brightness means that even this cannot save the Philips PML8709 in this category.

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.

Although theoretically the Filmmaker mode on the Philips PML8709 should provide natural color reproduction, in reality it resembles a store mode more. In the white balance, both for HD and 4K content, there is a clear dominance of blue. This makes the image appear washed out and cold, which is particularly noticeable in the comparison picture below.

The brightness characteristics also leave much to be desired. Both the gamma and the EOTF curve show excessive screen brightness. As a result, there is a loss of detail in both the brighter and darker parts of the image, which further diminishes its credibility and naturalness. Bright elements appear unnaturally flat and little varied.

These significant problems in white balance and brightness characteristics lead to noticeable color reproduction errors, which can be easily seen in films as well as in the Colour Checker test. The colors are imprecise, affecting the overall image quality and visual experience. The factory settings require substantial improvement to fully enjoy the potential of this television.

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.

Philips offers advanced image calibration tools in its televisions, which we decided to fully utilize. The effects? While we managed to improve many aspects, it was not without difficulties. White balance was one of the biggest challenges – despite our efforts, it can be called a battle against windmills. We managed to correct it significantly, making the image look much better than in the factory settings, but it is still far from perfect. Particularly in some scenes, a subtle dominance of blue is noticeable, though not as intense as before. We achieved significant improvement in brightness characteristics – gamma now presents itself much more stably. The EOTF curve looks correct at first glance; however, when analyzing film content, it becomes evident that the television has difficulty maintaining the appropriate characteristics. The algorithms "struggle" to adjust brightness, which may result from the limited number of dimming zones that do not always cope with more complex scenes. Overall, the image after calibration looks much more pleasant to the eye – colors are more natural, and errors in color reproduction have been minimized. Although it's still not perfect, the Philips PML8709 now presents itself much better than in the factory settings.

The fluidity of tonal transitions in LG TVs has long been a delicate issue, as the manufacturer, despite excelling in many areas, has consistently faced challenges in this aspect. However, the tested TV performed notably well in this regard. Issues were primarily confined to darker scenes, particularly the final two, where imperfections were more apparent. Interestingly, this model delivered better results in tonal transitions than LG's flagship model, the G4, showcasing a commendable improvement in this area.

The smoothness of tonal transitions in the Philips PML8709 is at a very high level. Color gradation is extremely smooth, and transitions between shades look natural and detailed. Even in more demanding scenes, the television performs excellently. Minor issues may arise with bright elements, where the gradation can be slightly less precise. However, these are such subtle differences that only the most demanding purists will notice them. For most users, the effects will be fully satisfying, and the image will maintain its impressive quality.

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 distortion reduction function in the Philips PML8709 smooths tonal transitions, but its effectiveness leaves much to be desired. We recommend setting this option to "Medium" – at this level, the effect is noticeable but not excessive. Unfortunately, compared to other Philips models, the smoothing effect is less effective, meaning that some tonal transitions may still appear slightly uneven. An additional drawback is that this function also smooths other details, such as material textures like shirts, which can affect image sharpness.

As for image scaling, the television performs very well. The image appears plastic and free of noticeable "jaggies." This effect may appeal to many users, although some may prefer a more pronounced look. Fortunately, the television allows for adjusting the sharpness parameter, enabling us to tailor the image to individual preferences.

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.

Philips PML8709 is one of the few models with mini-LED technology on the market that offers a refresh rate of 60 Hz. Although it is not a panel for the most demanding gamers, it should satisfy those who mainly watch movies. The television is equipped with the "Motion Style" feature, which is a motion smoother that allows you to adjust the fluidity of motion according to your preferences – from a more "plastic" appearance to a cinematic aesthetic with clearly visible frames.

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.

Philips PML8709 is a television aimed more at occasional gamers, mainly due to its 60 Hz panel, which does not meet the expectations of the most demanding users. However, for those who appreciate gameplay at a more measured pace, this model may prove sufficient.

The television offers several gamer-friendly features, such as ALLM (automatic switching to game mode) and VRR (variable refresh rate), which help in displaying images more smoothly without annoying stutters. Moreover, in terms of HDR, we find here the implementation of HGiG, which adjusts the HDR effect to the specifics of games, providing a more natural image in appropriately optimized titles. Unfortunately, there is no support for Dolby Vision mode, which may be felt in games that utilize this format.

A nice addition is the presence of a basic "Game Bar," which allows for quick preview and modification of key settings related to gaming. It's a simple yet helpful feature, especially for those who often change their setup between different types of gameplay. Despite certain limitations, the Philips PML8709 offers a solid set of features for less demanding gamers.

The latency time of the LG C4 is exceptionally low across all scenarios, making it a standout choice for even the most dedicated gamers. At demanding settings of 4K 120 Hz with HDR, the input lag is an astonishingly low 5 ms, ensuring an incredibly responsive gaming experience. Notably, this low latency remains consistent even when Dolby Vision HDR is enabled—a feature that competitors often struggle to maintain without increasing delay.

This consistency and performance firmly position the LG C4 as a top-tier option for gamers seeking high-quality visuals and minimal lag. It undoubtedly earns the highest rating and strong recommendation for gaming enthusiasts.

The Philips PML8709 performs very well in terms of input lag. With supported resolutions, results of around 13 ms are more than sufficient to ensure comfortable gameplay. Such a response time means that even more dynamic games do not cause annoying delays. This allows players to enjoy smooth gameplay without unnecessary stress.

When paired with a PC, the LG C4 delivers excellent performance, largely due to its impressively low latency of 13.5 ms, ensuring a near-instantaneous response between the mouse, eye, and screen. This makes it an ideal choice for tasks requiring precision and speed.

One of the most crucial aspects of using a TV as a monitor is text readability, and in this regard, the LG C4 excels. The text appears sharp and clear, although enabling the passthrough option in the settings is necessary to optimise font sharpness.

The RWBG pixel layout is another advantage, as it does not significantly affect the clarity of fonts or letters—a notable improvement compared to Samsung's QD-OLED panels. Whether using Windows or macOS, the LG C4 ensures a smooth and satisfying user experience for work or general PC use.

Philips PML8709 offers a dedicated mode for PC, but its capabilities are highly limited. The TV does not support chroma 4:4:4, which significantly affects the readability of fonts – text appears blurred and is difficult to read, disqualifying this model for those planning to use it as a monitor for work or document browsing. Additionally, although the TV demonstrated compatibility in G-Sync tests, the image while using this feature is very unstable, with frequent stuttering. Such unpredictability eliminates the benefits that adaptive sync support should provide.

The only positive aspect regarding PC compatibility is the low input lag, which can be an advantage for those using the TV mainly for gaming. Nevertheless, the limitations in chroma support and issues with G-Sync mean that the PML8709 is not the best choice for PC users.

One of the undeniable strengths of OLED panels is their exceptional performance for group viewing, allowing for consistent image quality from a range of viewing angles. The LG C4 upholds excellent contrast, colour saturation, and fidelity, ensuring a satisfying experience for viewers in different seating positions.

While it lacks the enhancements provided by MLA (Micro-Lens Array) technology, the C4 still delivers impressive results that most owners are likely to find highly satisfactory. However, at sharper angles, a slight greenish tint can sometimes be observed. This is a known characteristic of LG’s WRGB panels without micro-lens technology and, unfortunately, is an inherent limitation that cannot be mitigated.

Philips PML8709, equipped with a VA matrix, offers average viewing angles typical of this type of panel. The picture loses quality when viewed from a larger angle – colors fade, and contrast significantly decreases. This is a characteristic feature of VA matrices and should be kept in mind, especially if we plan to watch the TV from different places in the room. For viewers sitting directly in front, however, the image remains clear and well reproduced.

The maximum brightness of the LG C4 in SDR content reaches 367 nits, which is an impressive result for an OLED television and ensures comfortable viewing, even during the day. Two notable aspects enhance the experience. First, the glossy coating on the panel effectively contains light reflections, preventing them from spreading across the screen and disrupting the image.

Secondly, the brightness of the screen at 100% white fill measures approximately 220 nits, a significant improvement over earlier OLED models, which often struggled to achieve even half this level. This enhancement provides an excellent viewing experience, particularly for bright and vibrant content such as winter sports broadcasts.

The Philips PML8709 is equipped with a satin matrix, which handles glare suppression moderately well. In moderately lit rooms, reflections will not be too bothersome, however, in very sunny conditions, the situation can become problematic. An additional challenge is the relatively low screen brightness, which is about 330 cd/m². This level may prove insufficient for comfortable viewing in bright rooms, where the image can appear too dark and unclear. The TV will perform better in controlled lighting conditions, but for those looking for a model that copes well during the day, this may be a significant limitation.

LG has used its well-established proprietary WebOS system, a staple in its televisions for many years. This system provides access to virtually all major applications, with only a few notable exceptions, such as CDA or KODI. Additionally, the modern web browser and the remote control with a built-in mouse make streaming services easily accessible, even when specific apps are unavailable. One of WebOS's standout features is its ability to operate using a cursor that appears when the remote control is moved, offering great convenience when entering queries or passwords.

WebOS also includes screen mirroring, AirPlay, and Bluetooth headphone connectivity. For users with hearing impairments, it’s worth noting that WebOS allows the simultaneous use of headphones and the TV speaker, providing added flexibility. For sports fans, the system has a handy alert feature that notifies users of an upcoming match, ensuring they never miss a game.

Another highlight is the home panel, which enables users to control all smart devices connected to their home network. For example, a completed washing cycle will trigger a notification in the upper right corner of the screen.

In conclusion, while WebOS may not be as widely known or feature-rich as Android TV, it offers stable, fast performance and supports the majority of functions that users need. It is a solid and reliable option for those seeking a simple, effective, and user-friendly operating system for their television.

The Philips PML8709 runs on the Google TV operating system. This is quite a surprising choice, considering it is not the flagship model of the brand. Fortunately, it has avoided the implementation of the less popular TitanOS, which can be seen as a plus. Google TV offers a well-known, clear interface and extensive capabilities for installing applications, making the television more versatile.

In terms of user functionality, the television performs solidly. Daily use of the device is enjoyable thanks to support for Polish voice search. The ability to connect peripheral devices, such as keyboards, mice, or headphones via Bluetooth, increases its functionality. Unfortunately, the PML8709 does not offer more advanced options such as USB recording or PiP (picture-in-picture) functionality, which may disappoint more demanding users.

An interesting fact, and also a significant surprise, is the lack of Ambilight technology, which Philips is widely known for. The decision to omit this technology in the PML8709 model seems incomprehensible, especially since Ambilight is often cited as one of the biggest advantages of televisions from this brand.

The default file player on the LG C4 handles various photo resolutions without issue, making it a reliable option for viewing images. It supports nearly all popular video formats, including Dolby Vision, ensuring compatibility with high-quality content. However, the television does not support H.266 VVC codec, which is relatively rare at this stage, so this limitation is not a significant drawback.

A notable omission is the lack of support for subtitles in the .txt format, which could be inconvenient for users who prefer using text-based subtitle files. In terms of photo formats, the C4 supports only three: JPEG, PNG, and HEIC (the latter being particularly useful for Apple phone users). While this is somewhat limited, it covers the most common formats for everyday use.

The TV excels in audio file compatibility, with no issues playing a wide range of audio formats, ensuring seamless music and sound playback without any compatibility warnings.

The Philips PML8709 handles multimedia file playback from USB well. The TV should have no problem supporting most popular video, audio, and photo formats, making it a versatile tool for home entertainment. Files are read smoothly, and the interface of the built-in player is simple and intuitive.

However, a significant downside is the lack of support for Polish characters in subtitles, due to the incomplete implementation of the UTF-8 standard. Subtitles with Polish characters are displayed incorrectly, which can be irritating for people watching movies in their native language. This shortcoming means that users seeking full compatibility with subtitles may have to turn to external media players.

The LG C4 audio system is well-tuned, providing strong bass and balanced mid and high tones. It stands out as one of the better-sounding televisions in its price range. However, most buyers will likely already have a dedicated audio setup. The presence of DTS-HD Master Audio and Dolby Atmos codecs enhances the overall experience, offering high-quality sound for those who rely on the TV's built-in speakers.

The sound quality in the Philips PML8709 is average and standard for a television equipped with 2 x 10 W speakers. The sound is sufficient for everyday viewing, but it's hard to expect deep bass or clear details in more demanding scenes. On the plus side, it does support Dolby Atmos and DTS.
