How shall the automatic power down function be implemented for these products?

Some displays include the capability of powering other devices, for example computer displays providing a USB Type-C or Thunderbolt connector for a laptop. 

Displays capable of powering other devices are not exempted from the automatic power down requirements in Annex II C even if the power delivery function remains active. However, the power demand limits for off mode, standby mode or networked standby mode are not applicable when the display is delivering power to an external product (e.g. providing charging functions). The display shall be tested for these limits without delivering power to an external product.
