SP-SW1900-HD Users Guide
If a user connects to the SW1900-HD, the SW1900-HD will automatically turn the display on.
When the last person disconnects, the SW1900-HD will wait 30 seconds of inactivity then turn
off the display. In many cases, this feature eliminates the need for television remotes, extends
display life, saves power, and simplifies classrooms, conference rooms, and huddle spaces,
making them more user friendly.
