Sharp FQ8 vs Philips PML8709

The Sharp FQ8 achieves a maximum brightness of over 450 nits, which is commendable for its price range. While this level might not be groundbreaking, it places the television among the better-performing models in its class. At this brightness, the image appears vivid and detailed, and the HDR metadata functions effectively, offering a more immersive viewing experience compared to dimmer devices.

The television supports the advanced Dolby Vision HDR format, enhancing the depth and richness of the content. It also includes Dolby Vision IQ, which adjusts the image's brightness and colours based on ambient lighting. However, the implementation of this feature on the Sharp FQ8 is suboptimal, introducing artificial brightening and noticeable distortions. For this reason, it is advisable to disable Dolby Vision IQ for the most accurate picture quality.

With quantum dot technology, the television achieves a colour gamut coverage of approximately 94%, resulting in vibrant and realistic colours. This combination of features ensures the Sharp FQ8 delivers an engaging and detailed visual experience, even with some limitations.

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 difficult to explain. The average brightness we managed to achieve was just 350 nits, which is definitely too low to fully enjoy HDR effects. In practice, the TV barely stands out compared to an average SDR. The situation becomes even more surprising in test scenes, such as the second one from the movie Life of Pi or Sicario 2. Small light elements achieve just 120 nits there, making them practically imperceptible. Such a level of brightness is completely below modern HDR standards and significantly diminishes the experience of watching high-quality content. The only bright spot in this category is the very good coverage of wide color gamuts – DCI-P3 at 97% and BT.2020 at 83%. This ensures that colors are saturated and well-reproduced, which can somewhat improve the overall experience of watching HDR materials. However, the lack of adequate brightness means that even this cannot save the Philips PML8709 in this category.

The Sharp FQ8 was evaluated for colour reproduction in its movie mode, which provides the best default settings for achieving realistic visuals. While it performs adequately, certain issues impact the overall image quality. Tests on HD content revealed significant white balance problems, with a marked dominance of red. This is evident in the colour graph, where the red line noticeably rises above the others, and in practical tests, such as a movie scene featuring a child, where the image appears overly warm and unnaturally red. Similar issues persist with 4K HDR content, where an excessive red tint detracts from the accuracy of colour reproduction, an important consideration for viewers prioritising faithful visuals.

For SDR contrast, the gamma graph displayed an unusual anomaly at the start, highlighting reproduction issues. The remainder of the gamma curve lies below the reference line, indicating suboptimal brightness and contrast levels for standard content. In 4K HDR, the EOTF curve also deviates significantly, suggesting inconsistencies in brightness reproduction. These fluctuations can result in less enjoyable viewing experiences for HDR content, particularly in scenes requiring precise light and dark balance.

Though theoretically the Filmmaker mode in the Philips PML8709 should provide natural colour 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 causes the image to appear washed out and cold, which is particularly noticeable in the comparative image below.

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

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

After calibration, the Sharp FQ8 shows notable improvements in its performance for SDR content. The white balance has been significantly refined, with all lines approaching the reference line. While the lines are not perfectly straight, the results are impressive for a TV in this price range. This adjustment enhances the naturalness and accuracy of colours, contributing to a more enjoyable visual experience. However, the gamma chart still displays the peculiar jump at the start, though the remaining line now aligns much closer to the expected outcome.

For HDR content, the white balance also sees meaningful improvements compared to the pre-calibration state, although it doesn’t perform as well as in SDR mode. This refinement results in more consistent and visually appealing colours, despite some remaining imperfections. On the downside, the EOTF chart reveals limited progress in contrast due to the lack of control over dynamic tone mapping settings, which hampers uniform brightness representation in HDR.

Despite these limitations, the calibration significantly elevates the Sharp FQ8, particularly in SDR mode. The improved white balance and colour reproduction deliver a more natural and pleasant viewing experience. While HDR content still leaves room for improvement, the TV achieves a respectable level of performance, solidifying its position as a strong contender in its price range.

Philips offers advanced image calibration tools in its televisions, which we decided to fully utilise. The results? Although we managed to improve many aspects, it wasn't without difficulties. White balance was one of the biggest challenges – despite our efforts, it could be called fighting against windmills. We were able to significantly correct it, so the picture now looks much better than in the factory settings, but it is still far from perfect. Especially in some scenes, a subtle dominance of blue is visible, although not as intense as before. We achieved a significant improvement in brightness characteristics – gamma now appears much more stable. The EOTF curve looks correct at first glance, however, when analysing movie content, it is evident that the television has trouble maintaining the proper characteristics. The algorithms are "struggling", trying to adjust brightness, which may be due to the limited number of dimming zones that do not always handle more complex scenes well. Overall, the picture after calibration looks much more pleasing to the eye – colors are more natural, and colour reproduction errors have been minimised. Although it is still not perfect, the Philips PML8709 now presents itself much better than in the factory settings.

The Sharp FQ8 performs adequately with its 10-bit colour reproduction feature, providing smooth transitions between grey shades in the light bulb photo. For optimal results, setting it to medium is recommended, as it avoids issues like grain smoothing or blurring key elements. The "low" setting also yields good results without introducing unwanted visual artefacts.

In terms of upscaling, the Sharp FQ8 TV handles video without overscan, making full use of the screen. The jagged edges of branches are noticeable, but the edges of trousers appear without any clear jaggedness, contributing positively to the overall image quality. Additionally, the TV's AI Super Resolution feature enhances clarity by artificially sharpening jagged elements, further improving the viewing experience.

The distortion reduction feature 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 certain tonal transitions may still appear somewhat uneven. An additional drawback is that this feature also smooths other details, such as the textures of materials like shirts, which can affect image sharpness.

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

The Sharp FQ8 features a 120 Hz panel, able to support playback at 144 Hz when connected to a PC, which should theoretically provide smooth motion rendering. The TV includes features designed to enhance film fluidity and reduce motion blur, crucial for more dynamic content. However, in the absence of Black Frame Insertion (BFI) technology, the panel's average response time leads to less-than-ideal results. This results in slight motion blur, which may be particularly noticeable when watching sports or during intense gaming sessions.

Philips PML8709 is one of the few models with mini-LED technology on the market, offering a refresh rate of 60 Hz. While it’s not a panel for the most demanding gamers, it should satisfy those who mainly watch movies. The TV is equipped with a “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” look to a cinematic aesthetic with clearly visible frames.

The Sharp FQ8 offers several features that cater to gamers, enhancing the overall gaming experience. Firstly, the television is equipped with HDMI 2.1, which brings several advantages. ALLM (Auto Low Latency Mode) automatically switches the TV to a low-latency mode when a gaming device is detected. VRR (Variable Refresh Rate) helps reduce screen stuttering by adjusting the screen’s refresh rate to match the number of frames generated by the console or PC, providing smoother gameplay, especially in dynamic games. Additionally, the TV supports G-Sync, which synchronises the image with the graphics card, preventing stuttering and screen tearing.

Despite these advantages, the FQ8 has some limitations. The lack of support for HGiG (HDR Gaming Interest Group) means the TV does not optimise the dynamic range for HDR games. Furthermore, while Dolby Vision mode can improve picture quality in supported games, it suffers from very high input lag.

Philips PML8709 is a television aimed more at casual gamers, mainly due to the 60 Hz panel, which won’t meet the expectations of the most demanding users. However, for those who appreciate gaming at a more moderate 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 providing smoother image display without annoying stutters. Furthermore, in terms of HDR, we find the implementation of HGiG, which adjusts the HDR effect to the specifics of games, ensuring a more natural image in appropriately optimised titles. Unfortunately, there is no support for Dolby Vision mode, which may be noticeable in games that utilise this format.

A nice addition is the presence of a basic "Game Bar," which allows for quick previewing and modification of the most important settings related to gaming. It’s a simple but useful touch, especially for those who frequently change their configuration between different types of gameplay. Despite some limitations, the Philips PML8709 offers a solid set of features for less demanding gamers.
