metal cover from this slot; then align your graphics card with
the PCI Express x16 slot, and press it in firmly until the card is
fully seated.
Step 2.
Replace the screw to fasten the card in place, and replace the
computer cover.
Makesurethatthegoldedgeconnectorofthegraphicscardissecurely
inserted.
Step 3.
Plug the display cable into your card; then turn on the computer
and monitor. To connect a D-Sub monitor to your graphics card,
use the D-Sub connector. To connect a flat panel display to your
graphics card, use the DVI-I connector. To connect an HDMI
monitor to your graphics card, use the HDMI connector.

You are now ready to proceed with the installation of the graphics card driver. Please refer to next
chapter for detailed instructions.
Step 4.
To connect an HDMI TV, follow the steps below to enable the S/PDIF in function for the graphics card.
1.
Connect the provided S/PDIF cable to the graphics
card.
2.
Connect the S/PDIF cable to the motherboard.
(the red wire connects to the S/PDIF out pin and
the black to the Ground pin)
How NVIDIA®SLITM (Scalable Link Interface) technology works:
In an SLI configuration, two SLI-ready graphics cards of the same model and the same manufacturers
are connected together via SLI bridge connector in a system that provides two x16 PCI Express slots
to scale graphics performance. The picture below shows that two graphics cards are linked in parallel
in an SLI configuration.
