Report 0x21 configures the cinematic mode settings, it can change the size and distance to the virtual 'cinema screen' and alter the brightness of the HDM screen. It also control the MIC's local 'sideband' volume in the headphones.
There are a number of other parameter, their function is unknown at this time.
