When a player's screen is in standby mode (the player is operational but the screen itself black) as the result of your Screen Control settings, are any other means, no Proof of Play impressions will be logged as there aren't any media assets playing on screen at such times.
Impressions will only log as a result of actual instances of media asset playback on screen.
How can I find out more?
