Things You'll Need:
- VGA adaptors (male to female)
-
Step 1
Install the KVM switch. Disconnect the monitor cable that is attached to your computer. Position the monitors and run the video cable from each monitor down to the switch. Since you are reversing the normal operation of a KVM switch (going from one computer to two monitors rather than from two computers to one monitor), install female-to-male adaptors on the ends of the cables running to the switch. Attach the monitor cables to either side of the KVM switch, making sure that they are solidly seated and secured. Run the video cable from the switch's single input to the back of your computer case.
-
Step 2
Turn on both monitors, then turn on your computer. Depending on which monitor is initially selected by the switch, you should see your desktop on one of the monitors.
-
Step 3
Route the signal to the second monitor. Most KVM switches have a button in the center to switch from A to B, but your switch may have a built-in keyboard shortcut. Consult your owner's manual.
-
Step 4
If you get video on both monitors, adjust the resolution. Use your operating system's display settings.
-
Step 5
Use the monitors, as needed. If you want to use both monitors at the same time, consider buying a dual-head video card.
