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.
