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.
TCL A300 offers several picture modes, but without a doubt, the movie mode performs the best. Unfortunately, although it is the best choice among the available options, it is not free from errors. Both in HD and HDR content, the image has a noticeably too warm tint – leaning slightly towards pink, which is particularly noticeable in snowy scenes. Instead of pure white, we get a pinkish hue that spoils the natural perception of colors.
The brightness management doesn't perform well either. For older HD materials, the image often seems too dark – as confirmed by the inflated gamma value. Conversely, with HDR content, the effect is reversed – the image is overly brightened, which we observed in scenes from the movie Pan. This lack of consistency also affects color reproduction accuracy – a test with the ColorChecker showed that many samples deviate significantly from the reference values.
Fortunately, TCL allows manual adjustment of the settings, so we decided to check how the television would perform after our professional calibration. The effects of this correction are described below.
