Connecting computers and other devices
NOTE
If you connect an audio output device to any of the display's USB Type-A receptacles, all the display's
audio output will be routed through this audio output device rather than through the display's internal
speakers or any external audio systems connected to the stereo 3.5 mm out connector or the S/PDIF out
connector.
Connecting an external display
You can connect an external display using
the HDMI 2.0 out connector on the
connector panel (pictured). The external
display will show the same image. This is
useful when you're using the display in an
auditorium or other large space where it
would be beneficial to have a second
display.
You can set the default resolution for the
HDMI 2.0 out connector in the settings
(see Display on page 64).
Connecting an external audio system
The display includes two 15 W speakers, which are designed to provide sound at the front of a room. You
might want to connect an external audio system if you're providing sound in a larger space.
You can connect an external audio system
to the display using the stereo 3.5 mm out
connector (pictured). Alternatively, you
can connect an external audio system
directly to a room computer.
