Philips PUS8359 (VA) vs Samsung U8000F (VA)

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

While the U8000F with a VA panel can still be praised for decent blacks, there are no longer any reasons to be impressed regarding brightness – especially in HDR scenes. The television reaches a maximum of just under 250 nits, which is simply too little to talk about any impressive light effects. Bright elements come off as pale, and scenes that should shine look rather flat. An interesting situation was observed during the test of a scene from the movie Sicario 2 – the screen noticeably darkened, as if the television were trying to hide its limitations in displaying blacks. One might get the impression that the device artificially darkens the image to improve contrast, but in practice, the effect doesn't make much of a difference, other than that we see less on the screen. Additionally, there's the issue of colors – the U8000F does not support a wide color gamut, so don't expect vibrant, saturated shades known from better models. The HDR image here resembles slightly brightened SDR and… maybe that’s even a good thing. For this model, it's not worth setting expectations for cinematic experiences – it's better to treat HDR as a modest addition.

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 Samsung U8000F has been tested by us in the best picture mode available out of the box – namely, Filmmaker Mode. This profile is supposed to provide a neutral, cinematic image, free of unnecessary enhancements and artificial beautifications. In the case of SDR content – mainly in HD or SD resolution – the television performed surprisingly well right out of the box. The only noticeable imperfection was brightness management. The gamma chart showed some deviations – slight brightening or dimming of certain tones – but in practice, it did not significantly affect the viewing experience. For a television in this segment, it performs quite well.

However, the situation is considerably weaker in HDR mode. Although white balance was still acceptable, color errors were very pronounced. In the Color Checker test, almost every sample was outside the target point, and the image itself looked unnatural – colors were shifted, sometimes too cool, at other times simply dull and lifeless. The main problem lies in the hardware limitations – the U8000F does not support the wide color gamut of DCI-P3, so it is physically unable to reproduce the colors anticipated by the HDR standard. And unfortunately, this is evident in almost every more demanding scene.

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.

Right out of the box, the U8000F offered quite a decent picture in SDR for its price range. However, we managed to slightly enhance it – we reduced a subtle purple tint and improved the gamma characteristics, giving it a more natural curve. Despite these adjustments, the TV still tends to brighten the brightest details a bit too aggressively – the gamma graph shows a clear dip that cannot be fully corrected.

On the other hand, in HDR mode, it is noticeably weaker. It's hard to talk about any significant improvement here – despite attempts to tweak the settings, the picture still presents considerable color errors. A Delta E exceeding 7 means noticeable deviations that couldn't be effectively reduced. Unfortunately, this is a limitation of the design itself – the U8000F was simply not designed for serious HDR. In everyday SDR viewing, it performs quite well, but when it comes to HDR content... it's best not to have too high expectations.

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.

When it comes to how the Samsung U8000F handles lower quality materials, we must admit that Samsung has made progress compared to its predecessor from last year – the DU7192 model, which theoretically occupies the same position in the lineup. This year's model is equipped with a feature for improving the fluidity of tonal transitions, which has been implemented much better than last year. Yes, the TV still uses quite strong algorithms that can distort details or remove film grain, but despite that – it can be confidently said that it works effectively. However, not everything went perfectly. The U8000F has noticeable issues with slight image stuttering when watching very old content in very low resolution. If someone plans to play their old VHS tape, they should be prepared for the image to appear slightly "choppy."

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.

The Samsung U8000F is equipped with a 60 Hz panel, so right from the start, it's clear that we shouldn't expect miracles. This is simply standard in this class – sufficient for everyday viewing but without any frills. The TV offers one motion enhancement slider – a feature called "Motion Blur Reduction," which allows us to adjust the smoothness of the image in movies. Higher settings give a more "theatrical" and smoothed effect, while lower settings help maintain the original character of the film with a slight 24p effect. An interesting feature is "Clear Motion LED," which is a BFI mode – inserting black frames between image frames to improve motion sharpness. However, in practice, the screen flickers heavily when it's activated, and it should be treated more as an experiment than something that genuinely improves gaming comfort.

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.

Samsung U8000F offers a basic set of features for gamers, which nonetheless may be sufficient for less demanding users. It has an automatic game mode – when a game is launched on the console, the TV automatically switches to low latency mode, significantly improving response time. It also includes a VRR feature, or variable refresh rate, which operates in the range of 48 to 60 Hz. This means that both Xbox and PS5 will not produce a "tearing" effect on the screen – as long as we stay within this range.

And unfortunately, that's about it when it comes to advantages. Additions like Game Bar or higher refresh rates are reserved for higher models of Samsung from the 2025 line. In theory, the TV also supports the HGiG function, which should adjust the HDR image to the intentions of game developers. Unfortunately – even though this feature appears in brochures and marketing materials – its configuration on the Xbox console turned out to be... impossible in practice.
