You should position the monitor and angle the screen to
minimize unwanted reflections from other light sources.
2. Connect the PC video cable.
Do not use both DVI-D cable and D-Sub cable on the same
PC. The only case in which both cables can be used is if they
are connected to two different PCs with appropriate video
systems.
To Connect the D-Sub Cable
Connect the plug of the D-Sub cable (at the end
without the ferrite filter) to the monitor video socket.
Connect the other end of the cable (at the end with the
ferrite filter) to the computer video socket.
Tighten all finger screws to prevent the plugs from
accidently falling out during use.
To Connect the DVI-D Cable
Connect the plug of the DVI-D cable (at the end
without the ferrite filter) to the monitor video socket.
Connect the other end of the cable (at the end with the
ferrite filter) to the computer video socket.
Tighten all finger screws to prevent the plugs from
accidently falling out during use.
The video cables included in your package and the socket
illustrations on the right may vary depending on the product
supplied for your region.
3. Connect the power cable to the monitor.
Plug one end of the power cord into the socket labelled
"POWER IN" on the rear of the monitor. Do not
connect the other end to a power outlet just yet.
