Some models of Yamaha keyboards offer support for connecting to an external display through the use of a USB Graphics Adapter such as the UGA-165 or USB-VGA-165. While Plugable only supports these adapters with computers, select models of Yamaha keyboards offer plug-and-play compatibility to allow an external display to show Lyrics/Text or for Mirroring the keyboard's built-in display. 

The specific steps needed to connect an external display using a USB Graphics Adapter may vary by keyboard model, and can be found within the keyboard's Owner's Manual from Yamaha for keyboards that offer this functionality.
