Philips PUS8359 (VA) vs Samsung Q7F

The Philips PUS8359 has low brightness levels; however, dynamic tone mapping works surprisingly well, making it worth praising!

Unfortunately, the Samsung Q7F is not one of the bright televisions, and this directly affects the quality of HDR movies. The peak brightness of the panel is only about 250 nits, which is definitely too low to speak of true cinematic experiences. In practice, the image in HDR content does not differ significantly from classic SDR, making it hard to talk about any "wow effect" that usually accompanies us while watching such films. During testing movie scenes, the image simply looked dim, and brightness almost invariably hovered around the mentioned 250 nits. The worst performance was observed in shots with small, intensely glowing elements – the applied global dimming technique reacted very aggressively, dimming the entire screen to maintain the black effect. On the plus side, it is worth noting the presence of a QLED coating that expands the color palette. As a budget QLED model, the Q7F performs quite decently here: its DCI-P3 color coverage is about 93%, and BT.2020 reaches 70%. This means that colors, despite the low brightness, can look quite vivid and attractive.

The best factory mode for fidelity to the source material was the "Film" mode, which we used during our tests. As with all factory modes in televisions, it has flaws, and we’ll now examine what went wrong in both SDR and HDR materials. In both cases, the white balance showed an excessive dominance of green and red, resulting in a yellowish tint across the entire image. This caused issues such as yellowed whites and problems with skin tones. This was clearly illustrated on the "ColourChecker" palette, where each tested sample shifted towards warmer equivalents. The foundation of the image lies in contrast and black levels, represented by gamma charts and the EOTF curve. Looking at the gamma chart, we saw a real rollercoaster, with both elevated and lowered gamma. The 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, as it only mildly brightened the image.

The factory color reproduction in the Samsung Q7F definitely isn't one of its strong points. In Filmmaker mode, which theoretically should be closest to neutral, the white balance issue is immediately noticeable. There's too much red on the screen, while blue is noticeably lacking. The effects of this are very easy to see – white, instead of being neutral, takes on warm, almost slightly orange tones. Over time, this makes the entire image look somewhat unnatural, and bright areas of the scene can seem unrealistic. The problems become even more apparent in HDR content. The graphs show that the TV has significant errors in the Color Checker palette, which translates to visible inaccuracies in the real image. In practice, this means that colors are not presented as they should be. The Q7F also heavily manipulates brightness; darker elements are overly boosted, causing them to lose their cinematic feel, while bright parts can appear dimmed. As a result, the image seems flattened, and instead of helping to bring out details, contrast only highlights its own limitations. This is particularly frustrating in HDR materials, as every detail matters there. In scenes where a subtle play of light and shadow should be felt, the Q7F either overdoes the brightening or, conversely, suppresses elements that were meant to draw the eye. This causes the image to lose its depth, and instead of cinematic realism, we get more of a simplification effect.

Philips offers a wide range of image calibration tools in its higher-end and more affordable models. We used these tools, but the process was not as straightforward as many might expect. While we adjusted the white balance, significantly improved the gamma, and refined the EOTF curve in both SDR and HDR content, the deltaE errors remained extremely high. Several factors contribute to this situation, including the limited coverage of the DCI-P3 colour gamut and the unit's maximum brightness in HDR materials.

After professional calibration, we managed to bring the Q7F in order – at least in terms of SDR content. The picture in this mode looks really good: the white balance has been set correctly, the colors appear natural, and errors in the color palette have dropped to values that are practically invisible to the eye. The gamma behaves excellently, and the only minor drawback is a slight brightening of smaller elements, which results from the lack of local dimming. For everyday TV watching or standard quality films, the Q7F performs surprisingly well.

It was much more difficult to tame HDR content. Despite adjusting the white balance, the television continues to manipulate brightness significantly, causing scenes to sometimes look unnatural – what was meant to be subtly darker can end up being overly brightened, and bright parts of the image sometimes appear dull. The final effect is better than in the factory settings, but it is evident that the design limitations of the Q7F do not allow for fully utilizing the potential of HDR materials.

In this paragraph, we will take a look at two functionalities. We will once again look at the function 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 imperfections. However, we need to point out two things: we cannot enable it for HDR material and it blurs details in films.

The tested television cannot boast the best image scaling. There is a noticeable overall blurriness of the image, but what is worse, it blurs details. This is particularly visible on the branches and the model's hair. Additionally, a characteristic white halo can often be seen surrounding characters.

Upscaling and digital image processing in the Q7F is a bit of a sine wave. On one hand, we have really nice upscaling – weaker sources look better than one might expect. The image becomes clearer, sharper, and even older movies or terrestrial TV hold up well. Samsung has been strong in this area for years, and the Q7F confirms that. On the other hand… things start to get tricky. The TV has a problem with overscan – part of the image is simply cut off, and it looks rather unrefined. Additionally, we were let down by a feature called "noise reduction," which should improve the smoothness of tonal transitions in weaker materials. In other Samsungs, it works relatively well, but here it practically makes no difference – the banding in gradients remains. It's a bit disappointing because we could have expected more from a model that is aimed at users looking for a display for SDR content.

The Philips PUS8359 is not the best choice for watching sports. This is primarily due to the absence of even a basic motion smoothing feature, which given the price point, is not entirely surprising. Additionally, the television uses a VA panel, which, while offering high contrast, is not known for its sharpness or fast response times. As demonstrated in our analysis, fast-moving scenes often result in noticeable blurring, a common issue with this type of panel.

Although it is not an ideal option, the TV can be used for sports viewing with some compromises, particularly regarding motion sharpness. It's also worth noting that films are prone to stuttering since the TV lacks any form of motion smoothing, even the most basic functionality.

Motion blur and motion fluidity in the Q7F is probably the most budget-conscious element of this TV. The 60 Hz panel is noticeable, with blur being quite evident, especially in dynamic scenes, and it's rather difficult to consider this model as equipment designed for watching sports or playing fast-paced games. In tests with the little green man, there was a long tail, and the ball in a football match would leave trails behind it.

On the plus side, the presence of motion smoothing is commendable. It really makes a difference in movies - especially since most materials are recorded at 24 frames. Here we can decide for ourselves whether we prefer a more "cinematic" image, with the slight jerkiness characteristic of cinema, or a smoother, more "television-like" one. This actually works quite well and helps improve the viewing comfort for series or movies.

Unsurprisingly the Philips PUS8359/12 offers only the most basic support for consoles. When connecting a console, users can rely on features like VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode). VRR is particularly commendable, as even some higher-end models can struggle with this functionality.

A noteworthy addition is the implementation of a dedicated GameBar, which allows for on-the-fly adjustments without needing to exit the game, minimising unnecessary distractions. This feature also provides options to tailor gameplay for individuals with disabilities, making it a highly commendable inclusion.

Features for gamers in the Samsung Q7F is a topic that evokes quite a bit of mixed emotions. On one hand – no sensible person expected miracles here, after all, it's a 60 Hz television, and it was clear from the beginning that it wouldn't be a device to extract the maximum from a console or PC. On the other hand, since the manufacturer promised specific solutions in promotional materials, it's natural that we wanted to see them in practice. At the start, it's quite decent. The automatic game mode (ALLM) works, so there's no need to manually fiddle with the settings; the console switches the TV to low latency mode by itself. Additionally, we have the Game Bar, which looks impressive and allows you to check a few basic parameters without leaving the game. And this is where the good news ends.

The biggest problem with the Q7F is VRR, or rather its absence. Indeed, a relevant icon appears in the menu, and you can even see it in the Game Bar, but throughout the entire test, the function remained dead and could not be activated in any way. The issue with HGiG is even more painful; this option was actually available at the beginning, but after a software update, it disappeared completely, which is simply unprofessional. Therefore, the Q7F is only suitable for absolute basics. Sure, you can turn on the console, play more mellow titles, and enjoy low input lag, but if someone is counting on more advanced features that the manufacturer promised, they will be disappointed. This is not a television intended for gaming, and it's better to be aware of this before purchasing.
