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.
Like every Philips television we tested, we primarily evaluated the MLED920 in Filmmaker mode – this is supposed to be the "most honest" mode, designed for films and to faithfully convey the creators' intentions. Indeed, in terms of colorimetry, it performs the best among all the modes available on the television, but it is not without its flaws. The first thing that stands out is the white balance. The image has a slight tendency to take on purple-pink tones, which gives it a somewhat unnatural character. However, an even bigger problem turned out to be what we mentioned earlier – image clipping. Just look at the gamma or EOTF graphs to see that the line deviates significantly beyond the norm, falling below the value of 1.8. In practice, this means "clipping" the brightest whites, where the image becomes almost milky. Fortunately, most of these issues can be corrected – the MLED920 responds to calibration, and with a few adjustments, the image quality can be significantly improved.
