Philips PML9009 / 9019 / 9059 vs LG OLED C4

Philips PML9009 does not really operate at the highest values in HDR content. Most effects with brightness at around 550 nits will not leave us thrilled with the lighting effects, although they are quite stable, which is a plus and will make a considerable difference compared to SDR content. It is worth noting that we can only achieve a good result in one scenario, namely in the film "Gemini", where the flashlight as the only light source can shine. Why in that scene specifically? The answer is quite simple. The scene itself does not contain a large amount of black, and the flashlight is not as large an object as the sun in the first and last scenes. Overall, the brightness measurement results in HDR content do not provide a basis for recommending this television for viewing productions that utilise a wide colour spectrum. Although it is worth noting that this model can cover it to a decent extent of 93% in the case of the DCI-P3 palette.

The results of HDR materials are definitely among the better ones. Practically every film significantly exceeds the 700 nits barrier, allowing for a very realistic image. Of course, none of them surpasses the magical thousand, yet the combination of such results and unlimited contrast and black effectively boosts the outcome optically. The last of the scenes, featuring a full-screen burst of sunlight, is actually less bright than the others, although it still represents a commendable level. It is also worth mentioning the excellent coverage of the DCI-P3 colour palette, which will allow for achieving extremely vivid colours.

The best factory mode used during our tests was "Filmmaker". Here, we will look at both SDR and HDR content. The element that distinguishes them is primarily the EOTF curve in materials with a wide colour gamut and the gamma in those recorded "the old way". Starting with SDR films and series and the most basic thing we can observe, which is white balance, we see a significant dominance of red colour. This led to a yellow tint across the entire image, causing unnaturally looking faces and yellowed whites. This flaw is also evident on the "ColourChecker" palette, where all colours have shifted towards their warmer counterparts. Looking at a more significant graph, that of the gamma responsible for image contrast, we see considerable errors starting from the very beginning. From the left, the value we measured, marked by a connected ellipsis, clearly spiked upwards, causing complete merging of details in the darkest scenes. This state of affairs remained until 10% screen brightness, after which it dipped below the reference orange line, leading to a deterioration in contrast, which, as we know, the Philips PML9009 already lacks. In HDR materials, the white balance issues were very similar to those in SDR content. The discrepancy arises when checking the EOTF curve, which controls the rate of brightness increase and severely limited it, causing the image to appear unnaturally dark. As for the colours themselves, there were more reasons for concern here, as the television's too low luminance caused a huge discrepancy between the actual state and the correct one, which is perfectly visible on the error graph, often exceeding the scale.

The best factory mode implemented in the tested television was "Filmmaker". It was this mode that we used during all tests. This mode proved to be quite good in terms of colour reproduction; however, other shortcomings effectively detracted from the enjoyment of viewing. Starting with the most basic aspect, the white balance, it was easy to notice that it was marked by a dominance of red, which overall changed the characteristics of the image. We could thus see a strong yellowing of the whites and a shift of all colours towards warmer shades. The gamma, which is a curve just as important, if not more so, was quite significantly lowered, resulting in a considerable drop in contrast, except at the beginning of the graph, where the television insidiously lost details. That’s all regarding SDR materials. Taking a closer look at films with a wide dynamic range, we can observe exactly the same phenomenon of yellowing of the white balance as in films with a standard colour palette. The EOTF curve, which replaces our gamma curve, is practically perfect and cannot be faulted.

Philips PML9009, like most leading manufacturers, has been offering advanced tools for the calibration process for years. Thus, we find 2- and 20-point greyscale adjustment as well as an advanced CMS (Colour Management System). The differences resulting from calibration are evident, and even someone not paying attention to picture quality (although there probably aren't many such here) will notice a positive difference. Both SDR and HDR materials have undergone a significant transformation. The former, as well as the latter, have primarily rid themselves of the unpleasant yellow tint resulting from a red colour dominance in white balance. As for the SDR materials and gamma, although it is not 'lined up' perfectly and still loses dark details, the rest of it is on a more than decent level, and minor errors will not be noticeable. The colours themselves look infinitely better, and thanks to low deltaE errors, they are nearly reference-quality. On the other hand, the HDR materials, due to the low luminance of the unit, were not blended as we would have liked. Although the white balance has been largely normalised, here and there one can notice a slight blue tint. Fortunately, the EOTF curve turned out to be much more accessible and allowed for practically ideal geometry. Unfortunately, due to the screen's insufficient brightness, colour errors are still quite high.

As we mentioned earlier, LG televisions are equipped with advanced tools for carrying out the calibration process. We therefore used them to model the image in the way that the director intended. And without modesty, we must admit that we achieved this phenomenally. Both SDR and HDR materials present a level that clearly indicates that this is how a film should look. It is worth looking at the colour errors on the "ColorChecker" palette here, where practically none of them exceeds "1", apart from two samples.

Judging by how PML9009 Philips handled tonal transitions, the image scaling test should perform equally well. This time we are examining the television's algorithms responsible for enhancing the quality of images that have been recorded in lower quality. Such images can be found in various television programmes or older films. In this regard, Philips PML9009 performs quite mediocrely and significantly blurs the image. This is particularly evident in fine branches or the model's hair.

We will take another look at the tonal transitions, which performed remarkably. Within the unit, we find several levels of smoothing. Even the lowest setting can effectively eliminate any non-fluid tonal transition and will work well with the vast majority of content. More importantly, none of the settings for this function softens the effect of film grain, which is extremely important in terms of alignment with the director's vision. However, we note that sometimes it may turn out that fine details will be blurred.

Once again, we will take a look at the function responsible for smooth gradation, but we will also address the one that aims to improve the quality of lower-quality materials. The default smoothing of tonal transitions, as we have seen, was not the worst, but it can still be improved. The function has a slider, which allows us to adjust its strength. We recommend using the first one, as it yields very good results and does not blur important details.

Image scaling in 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. Admittedly, there are jagged edges on the trees, but this is not a major issue compared to other manufacturers.

Philips PML9009 is equipped with a panel that has a native refresh rate of 120 Hz. This is the essential minimum for watching all kinds of sports and is recommended for comfortable gaming in favourite titles on consoles or PCs. The manufacturer has prepared an effective system for improving the sharpness of moving images for those who do not like the characteristic stuttering of footage recorded at 24 fps or require a high level of motion fluidity, for example, when watching football matches. In the dedicated tab, we find the "Fluidity" slider, which helps eliminate stuttering, and "Motion Blur Reduction," which aids in increasing the sharpness of dynamic elements. This function works very well and granularly, meaning each setting has a real impact on the perception of motion. With such a set, every user will find their sweet spot. In the picture, we present our choice, which is a slight fluidity enhancement without the soap opera effect.

A matter directly related to motion is the pixel response time of the panel itself. The best in this regard are, of course, OLED panels, followed by IPS and ADS-based units, and finally, VA. Despite the overall good quality of the systems responsible for smoothing the image, the use of a VA panel carries consequences in the form of a black halo behind fast-moving objects. While this will not occur frequently in the tested television, it will be visible here and there.

The maximum refresh rate that we can set on the LG G4 is 144 Hz. Naturally, this is only possible when connecting the television to a very powerful PC. In other cases, we will be operating at a maximum refresh rate of 120 Hz, which is recommended if we primarily want to watch sport or content with a lot of motion dynamics. For those requiring high fluidity of the image, the manufacturer has implemented a multi-step 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 within a range from 0 to 10, with each degree affecting the degree of smoothing, allowing everyone to find their golden mean.

The LG OLED C4 panel features an average response time of less than 1 ms (which directly results from our measurements), allowing for an incredibly clear image that is unattainable for LCD televisions, whose response times can be as high as several milliseconds. This is clearly visible in the pictures from the "UFO Test," showing no trailing blur behind the object.

Philips PML9009, equipped with HDMI 2.1 ports at full bandwidth, supports all features dedicated to gamers. The most basic ones, such as VRR and ALLM, are a given, but G-Sync, FreeSync, and gaming in HDR Dolby Vision with low input lag are not. These features activate without any issues and during the tests conducted, they did not present any problems. Such preparation of the television is certainly a strong point and one can say that it is a unit dedicated to gamers. For more advanced users, we also mention that the PML9009 is equipped with an HGIG mode, which will be particularly felt by gamers, as there are still relatively few games supporting Dolby Vision. This mode primarily allows for the adjustment of HDR effects to the capabilities of the television on a special board, in order to avoid dimming or burning out the image.

The television additionally features a special menu - GameBar. This allows for editing the unit's settings "on the fly", without the need to exit the game. We will also find features such as enabling a crosshair or adjusting black levels for better visibility of opponents in shadows.

In a brief summary of this paragraph, the Philips PML9009 is a unit that will certainly capture the attention of gamers. Thanks to its versatility, it will allow playing any title in the highest quality without compromises. Especially since features such as VRR, ALLM, G-Sync, FreeSync, or gameplay in HDR Dolby Vision will enhance the immersion in the favourite title.

We can already say that LG C4, like practically every OLED television from the manufacturer, is exceptionally good in terms of compatibility with consoles and PCs. Thanks to the implementation of four full bandwidth HDMI 2.1 ports at 48 Gbps, the manufacturer has included all features that enhance the gaming experience, among which we find simultaneous support for FreeSync and G-Sync technology. With such a tandem, gamers with a graphics card from AMD or Nvidia can confidently opt for C4. However, what should delight the players requiring the highest possible quality the most is the simultaneous implementation of HDR Dolby Vision and HGIG mode. The first is particularly important as it works with extremely low input lag in all settings.

A standard in the Korean manufacturer's televisions is also the implementation of GameBar, allowing for quick adjustments of settings "on the fly" without the need to exit the game. It also enables image adjustments for visually impaired individuals, which is a very nice touch. Another important piece of information is that when VRR technology is enabled, we will not experience a drop in contrast. This is, of course, due to the panel's design and the absence of conventional backlighting. However, it is 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 of the manufacturer's OLEDs equipped with high refresh rate panels and HDMI 2.1 ports, creates a harmonious whole with consoles. In practice, it is a complete television, and if we expect the highest possible performance in gaming, C4 will be an ideal choice.
