A method of copying images displayed on a monitor onto a screen of a handheld electronic display unit includes electronically detecting the display unit when it is brought to the monitor, e.g., when the unit is connected to a port in the monitor's housing. After the user has received an indication that the display unit has been detected, the user selects an image displayed on the monitor's screen to be copied over to the handheld display unit. The selected image is displayed on the display unit's screen upon completion of the copying procedure. A preferred monitor for use with such a method has a housing that includes one or more data ports for receiving the handheld display unit. When a display unit is connected to a port in the monitor, both the screen of the electronic display unit and the monitor's screen are visible to a user positioned in front of the monitor.
