System Description
APPLICATIONS
The DynamicX2 system is a professional TFT display with an elegant housing
and an electrical lift system for installation into a horizontal furniture surface.
On the starting position (retracted), the screen is placed inside the table leaving
the desk free of any obtrusive elements. When in this position, the power will
automatically be disconnected in order to save energy and preserve panel life.
By pressing the rear button located on the table cover plate, the TFT panel
raises up into the working position (raised and tilted). The TFT power is then
restored.
