I initially thought that this TV lacked expert picture controls, to perform any advanced calibration, because I did not find any in the TV’s menu system. TCL informed me that the expert settings are actually available only through the Roku mobile app, so I grabbed my iPhone, opened the app, and located the “Expert Picture Settings” under the general Settings menu. Here you can choose from all the different picture modes, select from four gamma presets (1.8, 2.0, 2.2, and 2.4), enable noise reduction (off, low, medium, high), select from three color-temp presets (normal, warm, cool), access an 11-point white balance system, select a color space (native, auto, custom), and use the color management system to adjust all six color points. Basically, it’s everything you need to perform a more advanced calibration.”
