Connecting the Monitor to the PC
To connect the monitor video input to the PC:
1. Place the monitor upright, as shown in the following
illustration.
2. Connect the VGA or DVI-D (select models only) video cable
from the monitor to the VGA or DVI video connector on the
back panel of the PC.
✎
You can connect the VGA cable, the DVI-D cable, or both. Only
one cable is connected for typical installations. The DVI-D
connector (select models only) on the monitor is for digital-to-digital
connection only. If you connect both analog and DVI-D cables, the
PC connects through the analog cable by default. To change to
your DVI-D cable, you must change it in your monitor settings. Your
PC must have a DVI-compatible graphics card installed for use with
this DVI-D video cable. Your DVI-compatible graphics card may not
support the optimal monitor resolution. Refer to the documentation
that came with your graphics card.
