Using DVI Connectors with SLI Technology

The computer models that include dual graphics cards come configured with Scalable Link Interface (SLI) enabled. Dual graphics cards with SLI technology work together to render 3D applications to create a better performance experience.

IMPORTANT: In SLI mode only one of the top two DVI connectors is active. This means you cannot use the other three DVI connectors. If you do not have SLI mode enabled, you can use up to four of the DVI connectors on the back of the computer.

If you are not sure if you have SLI Mode, you can find out by completing the following steps:

1Right-click anywhere on the desktop, and then click NVIDIA Control Panel.

2On the left-hand side of the window, under 3D Settings, click Set SLI configuration.

3From the menu bar, click 3D settings.

4Click the drop-down menu and select Show SLI Visual Indicators. This window helps you to determine if SLI technology is enabled and working.
