Philips PUS8359 (IPS) vs Samsung Q6F (IPS)

The quality of 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 visible on the five tested images. Additionally, the television does not impress in terms of color gamut coverage – just 76% DCI-P3 is a result that can be considered weak, especially compared to other models in a similar price range.

Unfortunately, the Samsung Q6F is a very dark model. Its peak brightness in HDR does not exceed 250 nits, which is definitely too low to even speak of any "high dynamic range" effect, or HDR. In practice, it's better to stick to content in SDR format, which simply looks more predictable on this TV. Another problem is the global dimming technique – in scenes with a lot of black, the TV drastically dims the entire panel to artificially improve the black levels. This causes the image to become even darker, and brightness can drop below 100 nits. The only consolation is the QLED technology, but even here it's average. The applied quantum dot layer is not top-notch, as the coverage of the DCI-P3 color gamut does not exceed 90%. As a result, colors in HDR content may just seem under-saturated.

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

We tested the television in Filmmaker mode, which showed us two completely different faces of this model. Looking at SDR content, we were honestly shocked at how good this TV looks straight out of the box. It was really hard to nitpick anything here. Despite a slight “haze” in the white balance or somewhat brightened details in the blacks (which directly results from the IPS panel's design), color errors hovered around the “2” level. This is surprisingly good, even outstanding, considering the price of this device.

On the other hand, what the Q6F displayed in terms of colors after switching to HDR mode was a very unpleasant surprise. The errors in color reproduction and palette were so huge that our charts literally ran out of scale. Of course, since Samsung even in such an inexpensive model offers very advanced calibration possibilities, we decided to approach the subject professionally and check what could be done about it during calibration.

Philips, both in 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 simple as it might seem. We managed to adjust the white balance, improve the gamma, and tune the EOTF curve; however, despite these actions, the deltaE errors were still at a very high level. The main causes are limited coverage of the DCI-P3 color palette and low maximum brightness, which significantly affected the final result. Although the overall presentation looks much better, the design features of the TV did not allow us to achieve spectacular results.

After our calibration, the colors in SDR mode looked even better – the result is quite surprising, as color errors at level "1" are something usually seen in devices costing several thousand dollars. In this regard, the Q6F is really a great screen for everyday television, less demanding series, or movies. Unfortunately, our interference in HDR mode did not bring about a noticeable improvement. The television, due to its poor black levels and low coverage of a wide color gamut, still has significant problems with proper color saturation, especially red. This is an example of a device where HDR mainly exists as a label on the box – for everyday use, we definitely recommend watching content in SDR format.

In this paragraph, we will look at two functionalities. We will once again take a 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 the one called "Distortion Reduction." As we established, it quite effectively smooths out the choppiness. 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 the best image scaling. There is a noticeable overall blurriness of the image, but, worse, it blurs details. This is particularly visible on the branches and the hair of the model. A characteristic white halo around the character is also noticeable.

The Q6F handles upscaling lower resolution content to native 4K very well. The scaling is surprisingly good here, even for such a budget TV from the QLED series. The only downside is when we watch very low-resolution material, like 576p (typical for old DVD players) – then the image may be slightly cropped. This is because the TV does not allow for the Overscan feature to be turned off, which is a common issue with Samsung devices.

The situation is completely different when it comes to digital processing, which is the attempt to smooth the image from unwanted artifacts. Here, the TV completely fails. Although we find a function in the menu called "Noise Reduction", it yields no visible results regardless of the slider setting. The only thing it seems to do is introduce unwanted errors into the image. Despite its presence in the system, we definitely do not recommend using it.

Philips PUS8359 is not the best choice for watching sports. The lack of even basic motion enhancement features means that the picture in dynamic scenes is not suitably clear. Despite using an IPS panel (43 and 55'), which theoretically should offer better sharpness than VA panel variants, there is no noticeable improvement in terms of motion blur. In fast-moving images, it is clear that the UFO character is distinctly blurred, which indicates that the television does not cope well with maintaining sharpness in dynamic shots.

The 60 Hz panel in the Samsung Q6F is the standard in this price range, which makes it a rather average model for dynamic sports or gaming. However, in the case of movies, the TV performs quite well thanks to the smoothing feature. The "Motion Smoothing" option allows you to adjust the fluidity of motion to your own preferences – from maintaining a cinematic feel to full fluidity.

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

However, more demanding gamers may feel underwhelmed. The 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 capabilities in delivering smooth and detailed experiences during fast-paced, dynamic gameplay.

We won’t beat around the bush – the Q6F is not a television designed with gamers in mind. While it does have features like ALLM (Auto Low Latency Mode) and VRR frame synchronization for consoles, the list of benefits pretty much ends there. Besides these basics, the TV offers nothing more that might satisfy those who spend a lot of time in front of a console. It’s a real shame that such a useful tool as Game Bar is missing here, which in Samsung’s higher models allows for quick control of game parameters. In terms of gaming, this is an absolutely basic model and is only suitable for "casual" gamers.
