Sharp FQ8 vs Philips PUS8359 (VA)

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.

Philips PUS8359 didn't impress us with its performance in HDR materials. This model is capable of generating a maximum brightness of 320 nits, and often even less. Such results, combined with the lack of support for HDR Dolby Vision, mean that the image will be significantly darker compared to the source material. Therefore, it would be more beneficial for this television to play SDR content. This is also suggested by the quite low coverage of the DCI-P3 colour gamut at 83%, resulting in significant colour deficiencies. The fact remains that the television supports an HDR format based on dynamic metadata; however, HDR10+ is such a niche format that it doesn't offer any major advantages.

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.

The best factory mode in terms of fidelity to the source material was "Film". This is what we used during our tests. Just like every other factory mode in televisions, it had its drawbacks. So we'll check what exactly was wrong with both SDR and HDR materials. In both cases, the white balance exhibited an excessive dominance of the green and red colour combination. This created a yellow tint spreading across the entire image, causing issues such as yellowed whites and problems with skin tones. This state of affairs was perfectly illustrated on the "ColourChecker" palette, where each of the tested samples was pushed towards its warmer counterparts. The foundation of the image is primarily contrast and black. These are represented by gamma charts and the EOTF curve. Looking at the first one, we can see a true rollercoaster, as both elevated and lowered gamma can be observed. The heavily elevated gamma caused visibility issues in black levels, whereas the lowered gamma resulted in a dramatic reduction in contrast. In this context, the EOTF curve performed significantly better, as it only slightly brightened the image.

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 provides a wide range of image calibration tools in both its higher-end and budget models. We utilised these tools and got to work, which wasn’t as easy as many of you might think. While we managed to model the white balance, significantly improve the gamma, and refine the EOTF curve in both cases, the deltaE errors remained exceptionally high. There are several reasons for this situation, which are directly related to the low coverage of the DCI-P3 colour gamut and the maximum brightness of the unit in HDR material.

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.

In this paragraph, we will look at two functionalities. We will once again take a look at the feature responsible for tonal transitions, but we will also check how the television handles image scaling. The option responsible for smooth gradation is called "Distortion Reduction." As we have established, it quite effectively smooths out inconsistencies. However, we must point out two things: we cannot enable it for HDR material, and it blurs details in films.

The tested television does not boast the best image scaling. The overall blurriness of the image is quite noticeable, but what’s worse, it blurs details. This is particularly evident on the branches and hair of the model. There is also a characteristic white halo around the character.

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 PUS8359 will not be the best television for sports. The reason for this is the lack of implementation of even the basic motion smoothing feature, which was to be expected given the price of the device. We also note that we are dealing with a VA panel, whose sharpness does not stand at the highest level by itself. This type of panel is mainly associated with high contrast, which comes with a rather slow response time, as we can clearly read from the matrix analysis results. As you can see, from the pictures captured in fast motion, the image is blurred typically for this type of panel. While it may not be the ideal option, it can conditionally be used for watching sports; however, one must keep in mind the less-than-sharp motion. It is worth mentioning that movies will be characterised by judder since the television does not possess any, not even the simplest, motion smoother.

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.

It won’t be a surprise if we say that Philips PUS8359/12 only has the most basic support for consoles. Once we connect the console, we can expect features like VRR and ALLM. This is quite pleasing for the former, as life has shown that even in more expensive units, there can be issues with this. A nice touch is the implementation of a special GameBar that allows changing settings on the "fly", so we won't have to exit the gameplay and become unnecessarily distracted. This feature also allows for adapting the gameplay to the needs of individuals with disabilities, which will certainly be extremely beneficial.
