To connect two monitors to the video interface on your
computer, follow the steps below. If you want to connect three
monitors to the video interface, you can follow these steps, but
first see “Connecting three monitors” on page 15.
1. Make sure your monitors, the computer, and all other
peripheral devices are turned off.
2. If one monitor is already connected to your computer,
unplug its power cord from the electrical outlet and the AC
power inlet. Then disconnect the video interface cable(s)
from the monitor and the computer.
3. Connect each of the five T connectors to the first monitor’s
five BNC connectors, as shown below. To do this, align the
cutouts in the T connector with the tabs on the monitor
connector and plug in the T connector. Then push it in
while turning it clockwise as far as possible until it fits in
place.
