Philips PUS8359 (VA) vs Hisense A6Q

Philips PUS8359 did not impress us with its results in HDR materials. This model is capable of generating a maximum brightness of 320 nits, and often even less. Such results, combined with a lack of support for HDR Dolby Vision, mean that the image will be significantly darker compared to the source material. Therefore, playing SDR materials will be more beneficial for this television. This is also suggested by the rather low coverage of the DCI-P3 colour gamut at 83%, which results in significant colour deficiencies. The fact remains that the television supports the HDR format based on dynamic metadata, although HDR10+ is such a niche format that it does not bring any significant advantages.

The Hisense A6Q is unfortunately difficult to recommend for watching HDR content. The main issues are low brightness and rather modest coverage of a wide colour gamut. The measured brightness of around 300 nits simply isn't sufficient for HDR materials to look impressive. In practice, the picture often resembles standard SDR instead of true HDR with clear differences in brightness and dynamics. Additionally, the colours in such materials do not appear as they should. The television does not utilise additional filters such as QLED or PFS LED, and the coverage of the DCI-P3 colour space at around 80% means that some colours look rather washed out. Consequently, some scenes in HDR materials lose intensity and spectacle, making it difficult to speak of a full HDR experience.

The best factory mode in terms of fidelity to the source material was "Film". This was the mode we used during our tests. Just like each of the factory modes in televisions, it had its shortcomings. We will check what exactly was wrong in both SDR and HDR materials. In both cases, the white balance showed excessive dominance of the green and red colour combination. This created a yellow tint that spread across the entire image, causing issues such as yellowed whites and problems with skin tones. This situation was perfectly illustrated on the "ColourChecker" palette, where each of the tested samples was pushed into 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 we can observe both an elevated and a lowered gamma. The heavily elevated gamma caused visibility issues in blacks, while the lowered gamma led to a dramatic drop in contrast. In this context, the EOTF curve performed significantly better, only slightly brightening the image.

We conducted the tests in the best available mode, namely Filmmaker, however – as is often the case – this does not mean an ideal image straight out of the box. In the case of Hisense A6Q, this mode clearly "swallowed" too much blue in everyday SDR content. In practice, this led to an image with a yellowed white, particularly noticeable on large, bright surfaces. This is not due to poor assumptions of the Filmmaker mode itself or the vision of filmmakers, but rather the factory settings requiring adjustment.
Furthermore, looking at the saturation characteristics and the gamma curve in SDR, as well as EOTF in HDR content, there is a slight tendency to brighten most scenes. As a result, the image often appears brighter than it should, losing a bit of its naturalness. For this reason, we decided to perform a professional calibration to restore the proper colour balance and a more accurate brightness characteristic.

Philips offers a wide range of image calibration tools in both its more expensive and cheaper models. We utilised these tools and got to work, which was not as easy as many of you might think. While we were able to model the white balance, significantly improve the gamma, and refine the EOTF curve in both cases, the deltaE errors remained extremely high. There are several reasons for this situation, which are directly related to the low coverage of the DCI-P3 palette and the maximum brightness of the unit in HDR materials.

The colours after calibration in the Hisense A6Q should be assessed in two ways, as everything depends on the type of content. In the case of SDR material, the effect is truly very good. In everyday programmes, series, and films, it is difficult to spot any serious problems with colours. The yellow tint has been effectively removed, and the television no longer brightens the entire image. As a result, the ColorChecker test showed errors below Delta 2 values, which are already outstanding results, allowing us to speak of very high image quality in standard content. Unfortunately, the situation looks significantly worse in the case of HDR material. Yes, the white balance has been corrected and the EOTF curve has been improved, but the limitations of the panel itself remain insurmountable. The lack of support for a wide colour gamut means the television still generates quite significant colour errors. Certain colours simply cannot be displayed by the screen, making them appear less saturated than they should be. It's a shame because even a simple PFS or QLED filter would significantly improve the final effect. The conclusion is therefore simple – the A6Q is really very well suited for SDR content after calibration, while watching HDR content on it should still be approached with caution.

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

The tested television cannot boast of the best image scaling. There is a noticeable overall blurriness of 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 character is also visible.

Upscaling on the Hisense A6Q works quite decently for a television in this price range. Materials of lower resolution are correctly "upscaled" to a higher one, and the image remains clear without artificial edge enhancement or the typical "over-sharpening" found in cheap models. Unfortunately, the digital processing is significantly worse. In practice, it is difficult to speak of any advanced artifact smoothing or problematic tonal transition masking. In heavily compressed films – especially those from YouTube – the television practically struggles with reducing compression blocks and unwanted banding, making the imperfections in the material clearly visible. The A6Q scales the image well, but when it comes to digital processing, it leaves the user alone with the quality of the source.

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 is not of the highest standard. This type of panel is mainly associated with high contrast, which goes hand in hand with quite a slow response time, as clearly indicated by the matrix analysis results. As you can see from the images captured in rapid motion, the picture is typically blurred for this type of panel. Although it may not be the ideal option, it can be used conditionally for watching sports; however, one must keep in mind the less than optimal sharpness in motion. It is worth mentioning that films will exhibit judder, as the television does not have any motion smoother, even the simplest one.

The motion fluidity of the Hisense A6Q is… well — quite mediocre. It’s a television with a native refresh rate of 60 Hz in 4K, which means that the motion of objects on the screen doesn’t always look perfectly smooth. In dynamic scenes in movies or sports, it’s clear that this isn’t the strongest feature of this model. The situation improves significantly with 1080p content when connecting a console or computer, as the A6Q can operate even at 120 Hz then. This is a big plus, especially for gamers. Nevertheless, the clarity of motion still leaves much to be desired; blurring is noticeable, and the response time of the panel indicates that it is not one of this television’s strong points.

It will not be a surprise if we write that Philips PUS8359/12 only offers the most basic support for consoles. Once the console is connected, we can count on features such as: VRR and ALLM. This is quite pleasing in the case of the former, as experience 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 for changing settings on the "fly," so we won't have to exit the game and unnecessarily distract ourselves. This feature also allows for adapting gameplay to the needs of people with disabilities, which will certainly be extremely useful.

For such an inexpensive television, the Hisense A6Q can truly surprise with what it offers to gamers. It operates in 4K only at 60 Hz, but when a game switches to performance mode and drops to 1080p, the panel can work even at 120 Hz. This is a significant advantage in this price range, as most titles on consoles don't achieve stable 4K at 120 frames per second anyway. In practice, we are realistically playing at 1080p, and here the A6Q provides very enjoyable gaming experiences. On top of that, there are several features usually found in more expensive models: ALLM, VRR, and Dolby Vision Gaming for Xbox Series X/S. Everything is gathered in one place, in a simple and convenient Game Bar, so there's no need to dig through the entire menu. For such an affordable piece of equipment, it's a really solid set for gamers — perhaps not for the most demanding, but certainly spot on for occasional gaming.
