Philips PML9009 / 9019 / 9059 vs TCL C6KS / C69KS / Q6CS

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.

And what about HDR? Here, the C6KS performs quite well and – as has become a recurring theme of this review – identically to the C6K model. The maximum brightness generated by this television is around 600 nits. In bright scenes, this translates to a really solid, cinematic effect, and generally, the video materials look good here. However, one must keep in mind the specifics of the dimming algorithm in this model. When very small, bright points (e.g., stars) appear against a dark background, the television can dim them quite significantly. The goal is simple: to eliminate blooming and maintain the best possible blacks. This is quite a reasonable compromise. Most viewers will definitely appreciate deep, "true black" more than additional micro-details, the display of which could cause the screen to appear greyed out. This is the nature of local dimming technology in this price range, and one must be aware of it. It is also worth noting that the TCL C69KS (C6KS) has an additional PFS coating, which is marketed under the slogan of QLED technology. Thanks to this, the colours are saturated and vibrant – our measurements showed that the coverage of a wide colour gamut reaches as much as 92% here.

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.

Unlike the more expensive C6K model, the tested C6KS does not have an option in the menu labelled as Filmmaker Mode. Is this a reason to cry? Absolutely not. Our tests have shown that in practice, in terms of colour reproduction, the lack of this specific label makes virtually no difference. The best available Film/Cinema mode here offers an almost identical picture characteristic to the aforementioned Filmmaker in the more expensive model. So we get a very similar image, just under a different name. Therefore, if you were wondering whether paying extra for the C6K gives you better colours – the answer is no, in both cases the base is the same and requires slight adjustments.

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.

Thanks to the white balance adjustment, the C69KS's tendency to distort colours has been effectively limited, resulting in a very good final effect. After calibration, we will no longer see excessive warming of scenes in SDR or overly cool tones in HDR. However, it is worth noting the brightness characteristics. In SDR content, it is hard to have any objections – the image looks very good, especially in older films, television programmes, or materials from YouTube. It is significantly more challenging to evaluate the television's performance in HDR. Analysis of the EOTF curve suggests correct behaviour, but its practical variant reveals certain limitations. The C69KS can overly brighten the smallest elements of the frame, while at other times, it can dim the entire scene. Thus, calibration brought clear benefits in terms of colour quality, but certain limitations resulting from the local dimming operation and the way it is controlled by the C69KS cannot be overlooked, as we also saw in the C6K test.

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.

The C69KS handles upscaling quite well. The tested 576p material looks surprisingly decent – a considerable amount of detail is retained, and the algorithm adds a slight "rounding" effect to sharp edges, making the image appear more cohesive. The performance in smoothing tonal transitions is less impressive. The television practically cannot improve them, leaving the image in a rather raw state. With older material, this can be quite tiring, as the lack of additional processing highlights any imperfections.

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.

C69KS offers a simplified motion enhancement panel in films, allowing the adjustment of effect intensity with a slider. This makes it easy to match fluidity to personal preferences. The ability to use higher refresh rates is also a plus – although the panel operates natively at 4K at 60 Hz, lowering the resolution to 1440p enables 120 and 144 Hz modes, both on consoles and PC. This sounds like great news, however, in practice, the image at these settings exhibits significant motion blur. The effect is so pronounced that the overall presentation appears merely average and loses its appeal for everyday use.

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.

If we overlook the smudging and lack of native 4K at 120 Hz, the C69KS impresses with how well it performs during gaming. We get everything one can expect from a gaming television: variable refresh rate (VRR), automatic switching to game mode (ALLM), Dolby Vision Gaming mode, and a well-functioning HGiG. The television can also operate at 120 and even 144 Hz at lower resolutions, allowing for smoother gameplay on a console or PC. Additionally, there is a clear Game Bar that lets you quickly glance at key settings while gaming. As a result — despite a few limitations — the C69KS can be a really successful screen for gamers.
