How Do I... Solution Where to Find Additional Information
Set up my computer to use two
monitors? If your computer has the required
graphics card to support dual-
monitor setup, then look in your
shipping box for a Y-cable. The
Y-cable has a single connector on one
end (plug this connector into the
back panel) and branches into two
connectors (plug these connectors
into the monitor cables). See "Setting Up Your Computer" on
page 9 for information on connecting
dual monitors to your computer.
