Video display adapter for controlling a window covering

摘要

A system in accordance with the invention includes a video display adapter, such as a USB or HDMI dongle, configured to generate a signal when a video display (e.g., a television, projector, etc.) is turned on or off. A controller receives the signal and automatically actuates a motorized window covering in response to the signal. In certain embodiments, the motorized window covering receives the signal directly from the video display adapter without requiring any intervening electronic devices. A corresponding method is also disclosed herein.
