Nel caso specifico del c7, rtings dice di lasciare la luminosità a 50.
Per quanto riguarda la luminanza del pannelli oled, le impostazioni variano a seconda della luminosità della stanza.
"Luminance Settings
DARK ROOM
For calibration purposes, we adjusted 'OLED LIGHT' to 16 to reach our desired luminance of 100 cd/m² and this setting should be good for a dark home theater room or any viewing situation with a low light level. If this setting is still too bright for you, then you can still lower it further to better suit your need.

AVERAGE ROOM
For a room with an average lighting, adjusted 'OLED LIGHT' to 47 to reach a luminance of 200 cd/m². This setting should be good for any room with an average light situation, like an office. You can always adjust it to better suit your specific room.

BRIGHT ROOM
For our bright room setting, we adjuster the 'OLED LIGHT' to 100 (maximum) to get the maximum luminance available, and this setting should be good for any well-lit rooms with the direct sunlight of light from a very bright lamp. Again here it is good to note that this does not affect the colors, only the luminance of the display. "
