This is a photo from behind the portrait wall showing the mount for one of the 50" plasma screens. This photo also shows the control wiring, power wiring and devices associated with making this work. These plasma monitors served a dual purpose. They not only displayed portraits for the user, but by utilizing a separate feed, these monitors could also display video from the museum auditorium. A simple input change from within the control room would switch the video feed to allow this to happen.
