Philips PML9009 / 9019 / 9059 vs TCL C655 / C69B (55"-85")

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.

Generally speaking, the quality of the HDR effect on the TCL C655 / C69B looks quite promising. The average value in the test charts is around 450 nits, which already allows one to feel the light effects and better image dynamics. However, as previously mentioned, this effect may be partially subdued by slight differences in bright and dark colours, resulting from the lack of local dimming technology. However, the coverage of the DCI-P3 colour palette at 94% deserves high praise, and this is made possible by the use of a quantum dot (QLED) matrix. As a result, colours are vivid and accurately represented when watching HDR content.

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 television TCL C655 / C69B offers a film mode that has been tested for colour reproduction quality. Although this mode is called film mode, it unfortunately has several errors that a director would surely not want to see when recording their work. Starting with image analysis, it is worth examining the white balance – both in HD and 4K HDR content, the white balance has significant errors. In both cases, the red colour dominates, causing the colours to be too warm, and the overall result takes on a pink or yellow tint. This can be seen in the image below from the film "Star Wars". The Colour Checker test confirms these errors – the colour samples veer into incorrect shades, affecting the overall colour fidelity. A less significant issue is the brightness characteristic. However, this is also not without its flaws. The gamma graph shows a strong peak at the beginning, causing the image to be excessively brightened, and the EOTF curve responsible for brightness in 4K HDR material also has substantial fluctuations – it is noticeable how the television tries to maintain the appropriate brightness, but it does not always succeed effectively.

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.

After calibrating the television's film mode TCL C655 / C69B , the white balance has been adjusted, and the colours are presented as they should be – confirmed only by slight deviations in the Colour Checker test. The gamma is really quite accurate, which means the television should not have issues with brightness in low-resolution materials. Unfortunately, a similar EOTF characteristic is still visible, which is a natural phenomenon in televisions that do not have local dimming – they simply struggle to "shine" more in a given area of the screen. Despite this inherent limitation that cannot be bypassed, we recommend adjustment in the settings, as the overall colour presentation looks really very good.

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 television TCL C655 / C69B handles tonal transitions fairly well in low-quality materials. The "Gradual Smoothing" feature at a low setting effectively smooths out tonal transitions; however, it simultaneously blurs significant details, such as the texture of objects. On the plus side, it does not negatively impact the film grain, allowing the natural appearance of the image to be preserved. As for digital processing, the television adds artificial sharpness, which may appeal to some users who prefer a sharpened image. However, for those who prefer a softer look, this could be a disadvantage. A notable downside is that the image has been quite significantly cropped due to what is known as overscan, which reduces the field of view and trims the edges of the image.

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 television C655 / C69B is equipped with a 4K@60 Hz panel, which means it works best for watching films and less dynamic content. It also features a "Flicker Reduction" function that allows for the adjustment of image smoothness – the user can choose whether they prefer smoother motion or a more cinematic, frame-by-frame effect. The television can also adapt to lower resolutions, such as Full HD and 2K at 120 Hz, which will surely please gamers by offering a smoother image at the cost of resolution. It is worth noting that this feature is available in sizes from 55"+. Additionally, the largest variant, 98", is equipped with a 144Hz panel with full motion smoothing.

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.

The TCL C655 / C69B television offers nearly the perfect set of features for gamers, supporting all the most important technologies. It has an ALLM feature that automatically switches the TV to low latency mode, significantly improving responsiveness and minimising signal lag, which is especially important during dynamic gameplay. The VRR feature allows the screen refresh rate to synchronise with the frame rate generated by the console, eliminating screen tearing and providing smoother gameplay.

The television also supports Dolby Vision in game mode, which ensures better colour and contrast rendering in games that support this format, and the Game Bar provides quick access to settings related to gameplay, such as response time, latency level, and other parameters. Unfortunately, the C655 / C69B does not support 4K resolution at 120 Hz (the exception here is the 98" variant), which may be disappointing for more demanding gamers who expect the highest fluidity of image in high-resolution games. However, if we can forgo 4K, the television offers support for Full HD and 2K at 120 Hz, providing a smoother image and is a great alternative for those who prefer a higher refresh rate at the expense of resolution.
