Philips PUS8359 (VA) vs LG OLED C4

Philips PUS8359 didn't impress us with its performance in HDR materials. This model is capable of generating a maximum brightness of 320 nits, and often even less. Such results, combined with the lack of support for HDR Dolby Vision, mean that the image will be significantly darker compared to the source material. Therefore, it would be more beneficial for this television to play SDR content. This is also suggested by the quite low coverage of the DCI-P3 colour gamut at 83%, resulting in significant colour deficiencies. The fact remains that the television supports an HDR format based on dynamic metadata; however, HDR10+ is such a niche format that it doesn't offer any major advantages.

The results of HDR materials are definitely among the better ones. Practically every film significantly exceeds the 700 nits barrier, which allows for a very realistic image. Of course, none of them surpasses the magical thousand, however, the combination of such results along with unlimited contrast and black effectively boosts the visual outcome. The last of the scenes, featuring a fullscreen sun burst, is indeed less bright than the others, although it still represents a respectable level. It's also worth mentioning the excellent coverage of the DCI-P3 colour palette, which will enable the achievement of exceptionally vivid colours.

The best factory mode in terms of fidelity to the source material was "Film". This is what we used during our tests. Just like every other factory mode in televisions, it had its drawbacks. So we'll check what exactly was wrong with both SDR and HDR materials. In both cases, the white balance exhibited an excessive dominance of the green and red colour combination. This created a yellow tint spreading across the entire image, causing issues such as yellowed whites and problems with skin tones. This state of affairs was perfectly illustrated on the "ColourChecker" palette, where each of the tested samples was pushed towards 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 both elevated and lowered gamma can be observed. The heavily elevated gamma caused visibility issues in black levels, whereas the lowered gamma resulted in a dramatic reduction in contrast. In this context, the EOTF curve performed significantly better, as it only slightly brightened the image.

The best factory mode implemented in the tested television was "Filmmaker". That was the one we used during all tests. This mode, in terms of colour reproduction, turned out to be quite decent, although other flaws effectively detracted from the enjoyment of the viewing experience. Starting with the most basic one, which is white balance, it was easy to notice that this was marked by a dominance of red, which completely altered the characteristics of the picture. We could see a strong yellowing of the whites and a shift of all colours to warmer tones. The gamma, which is a graph as equally important, if not more so, was quite severely reduced, resulting in a significant drop in contrast, except for the start of the graph, where the television insidiously lost details. That’s all regarding SDR materials. Looking closely at films with a wide dynamic range, we can observe exactly the same phenomenon of white balance yellowing as in films with a standard colour palette. The EOTF curve, which replaces the gamma chart for us, is practically perfect and cannot be faulted.

Philips provides a wide range of image calibration tools in both its higher-end and budget models. We utilised these tools and got to work, which wasn’t as easy as many of you might think. While we managed to model the white balance, significantly improve the gamma, and refine the EOTF curve in both cases, the deltaE errors remained exceptionally high. There are several reasons for this situation, which are directly related to the low coverage of the DCI-P3 colour gamut and the maximum brightness of the unit in HDR material.

As we mentioned earlier, LG televisions are equipped with advanced tools for carrying out the calibration process. We used them to model the picture in line with what the director envisioned. And without modesty, we must admit that we achieved this phenomenally. Both SDR and HDR materials present a level that clearly indicates this is how a film should look. It's worth taking a look at the colour errors on the "ColorChecker" palette, where practically none of them exceed "1", except for two samples.

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

The tested television does not boast the best image scaling. The overall blurriness of the image is quite noticeable, but what’s worse, it blurs details. This is particularly evident on the branches and hair of the model. There is also a characteristic white halo around the character.

Once again, we will take a look at the feature responsible for gentle gradation, but we will also address the one that aims to enhance the quality of lower-quality materials. The default smoothing of tonal transitions, as we could see, was not the worst, but it can be improved further. The function has a slider that allows us to adjust its intensity. We recommend using the former, as it produces very good results and does not blur important details.

Image scaling on LG C4 is quite good, however, it cannot be said to be without flaws. The image is slightly sharper by default, although not in a very noticeable way. While jagged edges of trees can be seen, it is not a major issue when compared to other manufacturers.

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 does not stand at the highest level by itself. This type of panel is mainly associated with high contrast, which comes with a rather slow response time, as we can clearly read from the matrix analysis results. As you can see, from the pictures captured in fast motion, the image is blurred typically for this type of panel. While it may not be the ideal option, it can conditionally be used for watching sports; however, one must keep in mind the less-than-sharp motion. It is worth mentioning that movies will be characterised by judder since the television does not possess any, not even the simplest, motion smoother.

The maximum refresh rate we can set on the LG G4 is 144 Hz. Naturally, this is only possible when connecting the TV to a very powerful PC. Otherwise, we will operate at a maximum refresh rate of 120 Hz, which is recommended if we primarily want to watch sports or content with a lot of motion dynamics. For those who require high fluidity of the image, the manufacturer has implemented a multi-level motion smoother called "TrueMotion". It has been divided into two separate sliders that adjust the sharpness of moving images (De-Blur) and judder (De-Judder). Both sliders can be set in the range of 0 to 10, with each degree affecting the level of smoothing, allowing everyone to find their sweet spot.

The panel of the LG OLED C4 features an average response time of less than 1 ms (which directly results from our measurements), enabling the achievement of an extremely clear image, unattainable for LCD TVs, which can have response times of up to several milliseconds. This is clearly evident in the images from the "UFO Test," which show no trailing blur behind the object.

It won’t be a surprise if we say that Philips PUS8359/12 only has the most basic support for consoles. Once we connect the console, we can expect features like VRR and ALLM. This is quite pleasing for the former, as life 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 changing settings on the "fly", so we won't have to exit the gameplay and become unnecessarily distracted. This feature also allows for adapting the gameplay to the needs of individuals with disabilities, which will certainly be extremely beneficial.

We can now say that LG C4, like practically every OLED television from the manufacturer, is exceptionally good in terms of cooperation with consoles and PCs. Thanks to the implementation of four full-bandwidth HDMI 2.1 ports at 48 Gbps, the manufacturer has embedded all the features that enhance gaming comfort, including simultaneous support for FreeSync and G-Sync technologies. With such a tandem, players with graphics cards from AMD or nVidia can safely choose C4. However, what should please gamers demanding the highest possible quality the most is the simultaneous implementation of HDR Dolby Vision and HGIG mode. The former is particularly important as it operates with extremely low input lag in all settings.

A standard feature in televisions from the Korean manufacturer is also the implementation of GameBar, allowing for quick adjustments of settings "on the fly," without the need to exit the game. It also allows for image adjustments for people with visual impairments, which is an incredibly nice touch. Another important piece of information is that when VRR technology is enabled, we won’t experience a drop in contrast. This is, of course, due to the design of the panel and the absence of conventional backlighting. It is, however, normal for shades of grey to flicker slightly, although this is a characteristic feature of this function regardless of the manufacturer and television.

In summary: LG C4, just like all the manufacturer's OLEDs equipped with high-refresh-rate panels and HDMI 2.1 connections, creates a harmonious whole with consoles. In practice, it is a complete television, and if we expect the highest possible efficiency in gaming, C4 will be an ideal choice.
