Philips PML9009 / 9019 / 9059 vs TCL C9K

The Philips PML9009 struggles to deliver the highest HDR performance. Scenes with effects around 550 nits don’t provide particularly impressive lighting, though the effects remain stable, an improvement over SDR materials. A notable exception is in Gemini Man, where a flashlight as the sole light source stands out. This is likely due to the absence of large dark areas and the relatively small size of the light source compared to scenes with larger, brighter elements like the sun. While the brightness results in HDR content aren’t quite strong enough to recommend this TV for productions utilising a wide colour gamut, it’s worth mentioning that the model does achieve decent coverage, reaching 93% of the DCI-P3 spectrum.

As we mentioned with black and contrast – the C9K can make a huge impression in synthetic tests. Our measurements showed that on a screen 10% filled with white, the television is capable of squeezing out… 4000 nits of brightness! It sounds astronomical, but – and here, unfortunately, the pattern repeats – the numbers say one thing, and practice says another. In real movie scenes, the situation looks different. At best, when the light effects occupy a large part of the image and the local dimming algorithm does not have to think too hard about what to do with thousands of zones – the effect is really good. At that point, the C9K can reach around 1500 nits, which provides a pleasant, intense flash and can indeed make a positive impression.

The problem starts with smaller elements – such as stars in the sky, the moon, or single reflections. That’s when the proverbial cat comes out of the bag: the algorithms are not yet refined, and brightness drops to even 400–500 nits. That’s a huge difference compared to the potential 4000 nits we saw in laboratory tests. Why does this happen? Most likely, the television is trying to protect the blacks in this way and minimize the halo effect around bright objects. Unfortunately, this comes at the cost of details – some details simply vanish, and the scene loses its nature.

During testing, the Philips PML9009 performed best in the factory "Filmmaker" mode, which we evaluated across both SDR and HDR content. A key characteristic observed in this mode is the EOTF curve’s behaviour in HDR content and gamma settings in SDR, designed to enhance image accuracy. However, the PML9009 presented noticeable issues, particularly with white balance, as a pronounced red dominance created a yellow tint across the entire image. This affected skin tones and white areas, with faces and whites appearing unnaturally warm. The colour shift was confirmed through the "ColourChecker" palette, where colours leaned towards warmer shades.

In the gamma analysis, responsible for image contrast, we noticed considerable inaccuracies early on. Our measured values spiked above the reference, causing dark scenes to lose detail and merge visually up to about 10% screen brightness. Following this, the values dropped below the target line, further degrading contrast—an area already challenging for this model.

In HDR content, the white balance remained similarly flawed, and the EOTF curve also restricted brightness levels, resulting in a dim, muted image. Colour inaccuracies were even more pronounced here, with lower luminance levels causing large deviations from accurate colours, which were clearly visible on the error graph, often exceeding acceptable limits. While aiming for cinematic quality, this mode ultimately fell short in delivering balanced colour and contrast fidelity.

For color tests, as always, we reached for the Filmmaker mode – a new feature in TCL TVs for 2025. And while the direction itself is a step in the right direction, the execution leaves much to be desired. The white balance in SDR content turned out to be too warm – there was an excess of red. On the other hand, in HDR, it went in the opposite direction: the image became excessively blue. The Colour Checker test revealed quite a few color errors that were noticeable to the naked eye. An even bigger problem turned out to be what we mentioned above – brightness management. Regardless of whether we were watching SDR or HDR content, the image tended to blow out the entire scene, giving it an unnatural, even grotesque character. It's hard to call this a "director-created" mode – because the director has certainly never seen such an image.

Philips has long provided sophisticated calibration tools, including 2-point and 20-point grayscale adjustments as well as an advanced CMS (Colour Management System). These allow users to make significant improvements, and even those less attentive to image quality will likely notice a positive difference post-calibration. Both SDR and HDR content benefit from this process, notably eliminating the prominent yellow tint caused by an overemphasis on red in the white balance.

For SDR content, although gamma adjustments don’t entirely resolve the loss of detail in dark areas, the overall improvements bring most content to an impressive standard, with minimal, hardly perceptible errors. Colour accuracy is notably enhanced, achieving nearly reference quality with low deltaE errors.

HDR content, however, remains somewhat limited due to the display’s lower brightness capability. While the white balance has largely been corrected, a slight blue tint can occasionally appear. The EOTF curve aligns very well, providing accurate geometry, though colour errors persist due to the limited luminance. This calibration offers a substantial improvement but may still fall short for viewers who expect high brightness levels in HDR.

After calibration, we finally managed to tame the white balance – and it immediately translated into a more natural image. Colors finally started to look the way they should, and the overall presentation was incomparably better than in the factory settings. In other words – it’s worth taking a moment to improve this, as the gain is truly significant. The gamma responsible for managing brightness was also brought into order in SDR content, and the effect was more than satisfying. Unfortunately, when we turned on HDR materials, the situation quickly became complicated. No matter how we set the local dimming, the television had a tendency to do what it liked with the image – either it overexposed everything or dimmed the darkest parts too much. Exactly as we saw in the scene from the movie Billy Lynn. So, the color improvement after calibration makes a great impression, but brightness management in HDR remains the Achilles' heel of C9K and presents a certain technological limitation.

Given the impressive handling of tonal transitions by the Philips PML9009, one might expect similar success in the image scaling test. However, the results were less than stellar. When upscaling lower-quality images, like those from certain TV programmes or older films, the Philips algorithm tended to blur fine details noticeably, especially in intricate elements like fine branches or a model's hair.

On the other hand, the tonal transition performance remains noteworthy, with the TV offering several levels of smoothing. Even at the lowest setting, it effectively addresses non-smooth transitions in most materials, and crucially, it preserves the film grain effect, maintaining fidelity to the director's vision. However, it’s worth noting that some fine details may still appear slightly softened.

Digital image processing in TCL C9K is quite mediocre. The tonal smoothing feature seems to be present, but turning it on practically changes nothing – color bands are still visible, and it can unintentionally highlight elements we would prefer to hide, such as textures of objects. Fortunately, it doesn’t remove film grain, but that’s small comfort since the effects are still poor. Therefore, it's hard to recommend using this option.

On the other hand, image scaling performs much better. Lower quality materials look quite decent – characters and backgrounds are presented clearly, although, of course, with sources at 576p, physics cannot be fooled. Sometimes, characteristic aliasing on objects appears, but that’s the fault of the source itself, not the algorithm. A plus for not having issues with overscan – the image is not artificially cropped or enlarged.

The Philips PML9009 has a 120 Hz native refresh rate, a baseline standard for watching sports and an ideal setting for gaming on consoles or PCs. Philips includes an effective motion-enhancement system for users who want to reduce the stutter of 24 fps content or need fluid motion for fast-paced scenes, like in football matches. The dedicated "Smoothness" slider effectively mitigates stuttering, while "Motion Blur Reduction" enhances the sharpness of dynamic content. Each setting produces a noticeable difference, so users can tailor the motion effects to their preferences. Our recommended setup achieves a moderate smoothing effect, avoiding the exaggerated “soap opera” appearance.

Regarding pixel response time, VA panels like this generally fall short compared to OLED or even IPS panels, which can lead to a slight "black halo" trailing behind fast-moving objects. Although not a frequent issue with this TV, the effect can be seen in certain scenes.

Like the C8K, the C9K is also a really fast television – both figuratively and literally. It features a 4K panel with a refresh rate of 144 Hz, and at lower resolutions, the display can even ramp up to 288 Hz. This speed translates into practice – when watching sports or playing games, the image looks very smooth and clear. Additionally, in films, we get an extra motion smoother called Motion Clarity, which allows us to adjust the fluidity to our own preferences – from the cinematic "judder" frame to almost theatrical smoothness.

The Philips PML9009, with HDMI 2.1 ports supporting full bandwidth, is thoroughly equipped with gamer-focused features. Core functions like Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM) are included, as well as the additional perks of G-Sync and FreeSync compatibility and low-lag HDR Dolby Vision support. All these gaming features activate seamlessly, proving this model’s suitability for gaming. The TV’s HGIG mode, particularly beneficial for gaming, adjusts HDR effects to the television’s capabilities to avoid image dimming and blooming, an advantage given the still limited number of games supporting Dolby Vision.

For added convenience, the PML9009 has a GameBar menu, allowing in-game setting adjustments without needing to exit. This menu includes features like a crosshair option and black level correction, which can enhance the visibility of shadowed areas—ideal for competitive play.

Overall, the Philips PML9009 offers a comprehensive setup for gamers, supporting VRR, ALLM, G-Sync, FreeSync, and HDR Dolby Vision to deliver immersive, high-quality gaming experiences across a wide range of titles.

For gaming, the TCL C9K is a complete tool. Here we have two (out of four) HDMI 2.1 ports with full bandwidth of 48 Gbps, so all key technologies work: VRR (variable refresh rate) and ALLM (automatic low latency mode). Additionally, the manufacturer added a really intuitive Game Bar, which allows you to quickly preview the most important parameters and adjust settings without digging through the menu. Also, TCL's policy is a plus – the TV is not afraid of any HDR formats, even in game mode. Whether it's HGiG or Dolby Vision for the Xbox Series S/X console – everything works as it should, giving the player wide freedom.
