The external display shows the same image as the display. This is useful when you’re using the display in
an auditorium or other large space where a second display would be beneficial.
Important
If the connected external display doesn’t support High-bandwidth Digital Content Protection (HDCP),
no image will appear on the external display. For full resolution output, connect a display that
supports HDCP.
Note
The display’s default output resolution is 4K (3840 × 2160). The output resolution can also be set to
1080p 60Hz in display settings. See
Input and output
on page76.
Connecting an external audio system
The display includes two 20 W speakers, which are designed to provide sound at the front of a room. You
might want to connect a third-party external audio system if you’re providing sound in a larger space.
