Philips PUS8359 (IPS) vs LG QNED87T6B

The quality of the HDR effect on the Philips PUS8359/12 television is also not impressive. A brightness level of 280 nits is too low, resembling standard SDR more than true HDR, which is clearly evident on the five tested test cards. Additionally, the television does not impress in terms of colour gamut coverage – just 76% DCI-P3 is a result that can be considered poor, especially compared to other models in a similar price range.

LG QNED87T6B delivers truly decent visual experiences when it comes to HDR. During our tests on test patterns, the television achieved brightness close to 500 nits, which is a satisfactory result and allows for good visibility of details in high dynamic range scenes. Support for basic HDR formats such as HDR10 and HLG ensures proper image quality. Unfortunately, the television does not support more advanced standards such as Dolby Vision or HDR10+, which are particularly important at this screen brightness. The lack of support for dynamic metadata means that in certain scenes, the television may struggle to fully reproduce details, especially in very bright areas – this is precisely when dynamic metadata could significantly improve image quality. Nevertheless, it is worth noting the excellent coverage of the wide DCI-P3 colour gamut, reaching as much as 96.4%. As a result, the colours displayed by the QNED87T6B model are more vivid and natural, enhancing the quality of 4K content viewed with a wide colour palette.

The most faithful factory mode in terms of compliance with the source material turned out to be "Film," which was used in our tests. However, like other factory modes, it also had its drawbacks. Both in SDR and HDR materials, we noticed issues with white balance, where the dominance of green and red resulted in a yellowish hue. This effect was particularly evident in the form of yellowed whites and unnatural skin tones. The "ColourChecker" palette test showed that each colour was shifted towards warmer tones, which affected the accuracy of colour reproduction. A key aspect of the image is also contrast and brightness, which can be assessed by analysing the gamma charts and the EOTF curve. In the gamma chart, we observed significant deviations – both excessively high values that caused loss of detail in the shadows and excessively low values, which led to a drastic drop in contrast. Compared to gamma, the EOTF curve performed better, only slightly brightening the image, which had a less negative impact on overall quality.

The colour accuracy in the LG QNED, even in Filmmaker Mode, which is the best factory setting, is not without its flaws. The main issue is white balance – we noticed that the level of blue on the graph tends to drop. This results in a shift in colours towards yellow, making the image have a warmer tone than it should. This deviation affects the naturalness of colour reproduction, especially in scenes with a white or neutral background. The Color Checker test confirmed that some colours are distorted and deviate from reality. Such distortion can make film scenes appear less realistic, and details are presented in incorrect colours, negatively impacting the overall image quality.

Regarding contrast, the gamma graph analysis showed significant drops, while the optimal value should be 2.4. This means that the television may display darker parts of the image brighter in some scenes, which reduces their depth and dynamics. Additionally, on the EOTF curve, which is responsible for brightness reproduction, an unnatural drop was noted at the beginning. This phenomenon can result in less accuracy in reproducing dark scenes, which in turn affects the overall image quality. The television may not convey full black depth, causing more demanding scenes to lose realism and detail. As a result, viewers may notice that details in the darker parts of the image become less distinct.

Philips, in both its cheaper and more expensive models, offers a wide range of tools for image calibration. We used them to improve the quality of the displayed image, although it was not as straightforward as it might seem. We managed to adjust the white balance, improve the gamma, and fine-tune the EOTF curve; however, despite these efforts, the deltaE errors remained at a very high level. The main causes were limited coverage of the DCI-P3 palette and low maximum brightness, which significantly affected the final outcome. While the overall presentation is much improved, the design features of the television did not allow us to achieve spectacular results.

After calibration, the colours in SDR content look very good. The improved white balance translates to natural and harmonious shades in various scenes. Thanks to precise gamma tuning, details in shadows and bright areas of the image are accurately reproduced. The television performs excellently in everyday use, offering vibrant, well-balanced images and solid colour quality in HD. The biggest beneficiary here is also contrast. The gamma graph has been stripped of significant errors, giving the television a new dimension.

As for the white balance in 4K HDR, it has also been significantly improved. However, some errors still appear at the end of the graph. This may be due to the television's overly aggressive local dimming, which in some scenes affects the inaccurate reproduction of colours. It's difficult to talk about an improvement in brightness represented by the EOTF curve. The television, due to its construction limitations, has some drawbacks, and we can't overlook them. The Color Checker test confirms the issue with colour saturation – even though the television offers a wide colour palette, it fails to fully convey the director's intent.

Despite these shortcomings, the overall picture quality after calibration is significantly better than before. Adjustments in white balance and gamma tuning make the images more vivid and the colours closer to reality.

In this paragraph, we'll take a look at two functionalities. We'll once again examine the function responsible for tonal transitions, but we'll also check how the television handles image scaling. The option responsible for smooth gradation is called "Distortion Reduction". As we've established, it does a pretty good job of smoothing out inconsistencies. However, we must point out two things: we are unable to enable it for HDR content, and it blurs details in films.

The television being tested cannot boast the best image scaling. There is a noticeable overall blurriness in the image, but worse still, it blurs details. This is particularly evident on the branches and the model's hair. A characteristic white halo around the figures is also visible.

When it comes to lower quality materials, the gradation looks really good. The feature called "Smooth Gradation" effectively smooths out the most problematic parts of the image, while not negatively affecting the film grain. For the best effect, it’s worth setting it to a low level. This solution significantly improves the quality of the displayed content, making the viewing of lower resolution materials more enjoyable and smoother.

In terms of digital processing, the image is displayed without cropping, known as overscan. Although slight fraying of the branches can be noticed against the model's background, everything looks very good. Users should be satisfied with the image quality when watching low-quality materials like standard television. The TV handles this task exceptionally well, providing a satisfying visual experience, even with lower quality content.

Philips PUS8359 is not the best choice for watching sports. The lack of even basic motion smoothing features means that the picture in dynamic scenes isn't sharp enough. Despite using an IPS panel (43 and 55'), which theoretically should provide better clarity than VA panel variants, there’s no noticeable improvement in terms of motion blur. In photos of fast movement, it’s clear that the figure of the little green man is distinctly blurry, indicating that the TV struggles to maintain sharpness in dynamic shots.

The television provides decent smoothness when watching movies, thanks to the “Tru Motion” feature, which allows adjustment of motion smoothing from 0 to 10. De-Judder regulates motion smoothness, while De-Blur adjusts motion sharpness. Users have the option to choose between a traditional cinematic effect with subtle juddering motion (lower settings) and a smoother, theatrical image. Although the latter deviates slightly from the cinematic standard, it may be appealing to many viewers.

As for gamers and sports fans, the LG QNED87 television with a 120Hz panel will surely not disappoint. And with the use of an IPS panel, the response time is typically better than that of VA panels available at a similar price. This ensures smoother gameplay and dynamic experiences when watching sports events.

In terms of console compatibility, Philips PUS8359 is mainly suitable for casual gamers. Although the TV is equipped with an HDMI 2.0 port, it offers features such as Automatic Low Latency Mode (ALLM), Variable Refresh Rate (VRR), and Game Bar. ALLM automatically switches the TV to low-latency mode, making quicker reactions during gaming easier, while VRR smoothly adjusts the refresh rate, eliminating screen tearing issues. The Game Bar provides quick access to game settings and ongoing parameter monitoring; however, in our opinion, it performs worse compared to competitors' solutions.

However, more demanding gamers may feel disappointed. Philips PUS8359 does not support advanced HDR formats in games or higher refresh rates, which is due to the use of a 60 Hz panel. These shortcomings limit the TV’s ability to deliver smooth and detailed experiences during fast-paced, dynamic gameplay.

LG QNED offers a range of features that make it an excellent choice for gamers looking for a high-performance television. The TV is equipped with four HDMI 2.1 ports, allowing connection to the latest consoles like PlayStation 5 and Xbox Series X, utilising full functionality including Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM). Thanks to the Game Bar feature, gamers can quickly and easily manage all game settings without needing to navigate complex menus. Parameters such as VRR, ALLM, Multi View, and frame rate monitoring can be adjusted. The TV also supports G-Sync and FreeSync technologies, which is particularly important for owners of Nvidia and AMD graphics cards. G-Sync and FreeSync synchronise the TV's refresh rate with the graphics card. The 120Hz panel guarantees incredible motion smoothness and image clarity. Combined with the Black Frame Insertion (BFI) feature, which is available at 60Hz and 120Hz, gamers can enjoy an even sharper and smoother picture. LG QNED87 is a television that meets the expectations of even the most demanding gamers, offering modern technologies and features that significantly enhance comfort and satisfaction during gaming.
