To enable multi-display cloning
Make sure at least two DisplayPort monitors are connected through the same DisplayPort connector of the Quadro card, using certified cables and branching devices as needed.
From the NVIDIA Control Panel Select a Task pane, under Workstation, click View system topology.
Locate the Quadro product that has the DisplayPort connection that supports multi-display cloning, then click the corresponding board [+] icon to expand the branch.
Make sure that the EDID state is not set to (Forced). (See EDID Management)
At the DisplayPort status property, click Multi-Display Cloning (Disabled).
The Multi-Display Cloning page opens.
Click to select the Clone displays using check box, then click the list arrow and select one of the options for determining which displays will be included in the Clone Group:
Common native mode - Connected displays having the same native timing will be included in the Clone Group. The native timing with the largest number of supported displays is used. If multiple native timings are supported by the same largest number of displays, the higher timing will be used.
Highest common mode - Display timings supported by the largest number of connected displays will be used to determine which displays to include in the Clone Group. If multiple timings are supported by the same largest number of displays, the higher timing will be used.
Custom settings - This option is available only if other settings in the dialog box have been customized.
Your selection determines not only which displays are included in the Clone Group, but it also determines the specific mode parameters listed in the dialog box - resolution, refresh rate, pixel clock, color format, and color depth.
You can select different values for each mode parameter, which will in turn affect which displays are included in the clone group.
The available options for each parameter depend on the selection of other parameters as follows:
The resolution selected determines which refresh rates are available.
The refresh rate selected determines which pixel clocks (timing standards) are available.
The pixel clock selected determines which color formats are available.
The color format selected determines which color depths are available.
Click OK when done.
