Action
Use a DC 5.3V power adapter if

adapter, check that it matches the
system specifications (DC 5.3V),
and that it is plugged in and
functioning properly.
There are three DVI standards:
DVI-A; DVI-D; and DVI-I. Make
sure that the DVI specifications of
the source device, cable, and
monitor all match.
Note: Some monitors are able to
support multiple DVI signals.
DVI-D only supports resolutions
up to 1280 x 1024
Since Port 1 is the port that
supports DDC2B, there must be a
monitor that supports DDC2B on
Port 1.
The resolution of the monitor on
Port 1 must not exceed the
maximum resolution of any of the
other monitors.
The monitor on Port 1 must be set
to a resolution that the other
