the “Video in” port on the back of the DVI splitter.
3. Take the DVI male/female extension cables from the monitors and plug into the “DVI
out 1” and “DVI out 2” ports on the back of the splitter.
4. Connect the input power jack to the back of the DVI splitter and plug the power
adapter into the wall or power bar. Check to see if the power LED light is active on
the front of the DVI splitter.
5. Turn on the primary computer and all monitors.

adapter into the wall or power bar. Check to see if the power LED light is active on
the front of each DVI splitter.
3. Turn on the primary computer and all monitors.
