Whether you are using a laptop or a desktop computer, you can connect a second monitor. Newer computers have a DVI connection port for monitors. Older monitors may only have VGA ports, but you can still use the older monitor by obtaining a DVI to VGA adapter. When needing two monitors connected, you need a DVI to VGA splitter adapter.
Things You'll Need
- DVI to VGA splitter cable (desktop)
- VGA cable
Plug in the splitter cable into the DVI port of the computer if you are using a desktop. The splitter cable is "Y" shaped. You want the single end to connect to the port on the computer. The two other ends are for connecting the two different monitors. Because a laptop already has one screen built into the computer it only needs a single cable to connect the second monitor
Plug the VGA cable into the VGA ends of the splitter cable. If using a laptop, connect the single cable into the DVI port on the computer.
Connect the ends of the cables into the VGA port on the back of the monitors. If there are threading screws on the sides of the cables, tighten these clockwise. Doing so creates a secure connection between the cable and the monitors.
Power on the monitors and the computer and you can see the desktop displayed on the second monitor. If not, go to Start->Settings->Control Panel->Display->Settings tab (in Windows XP) to control how your displays are arranged and viewed.
