A splitter will only clone your displays. You wont get two separate displays so a copy of the first.
What video card do you. Most will let you hook up more than one display
Thanks for the fast reply and for the info! I didn't realize that splitters only duplicated the display. But anyway, I realized I have a VGA port and a DVI port so I could just grab a DVI to VGA adapter and use both the VGA and DVI ports to run dual monitors.
